Is climate change responsible for record cold in U.S.?

January 7th, 2014
03:04 PM ET

By Mick Krever, CNN

Are the record-low temperatures in the United States and Canada – not to mention the extreme flooding in the UK and a record heat wave in Australia – the result of climate change?

Maybe not, but that says nothing about the validity of climate change, Climatologist Richard Alley told CNN’s Hala Gorani, sitting in for Christiane Amanpour, on Tuesday.

“Maybe a little bit of climate change, but this is mostly weather – big, exciting weather,” he said. “We’ve only warmed it one degree, and this is a 20-degree cold snap. So mostly, this is weather.”

In other words, higher sea levels from greenhouse gases may have contributed to recent flooding in the UK, but the temperatures are mostly the result of a fluke event, the shifting south of frigid polar winds, known as the polar vortex.

But it’s not nearly as simple as just saying the cold snap is not a result of climate change.

“We know the globe is warm,” he said. “If you look today, the average temperature of the whole world is above its long-term average.”

Climate skeptics are using the record cold spell as an argument in support of their contention that the phenomenon is not real.

“We scientists don’t like to say ‘undeniable’ – we like to say very high confidence,” Alley said. But, he went on, if he drops his pen he can also say with high confidence that it’s going to fall down, not float upwards.

“Now if I drop my pen at the moment you turn on your giant electromagnet it might float up, but you know the answer.”

The science, he said, is undeniable.

“The knowledge that CO2 is a greenhouse gas and it has a warming influence we’ve had for more than a century,” he said. “And the real physics of it were refined by the Air Force after World War II when they were working on sensors for heat-seeking missiles.”

“In some bizarre sense, to deny global warming is to question the ability of the Air Force to put the right sensor on the heat-seeking missile.”

“Knowing that CO2 is a greenhouse gas doesn’t tell you who to vote for; it doesn’t tell you what taxes to support. It gives you knowledge that you can use.”

Responding to climate change, he said, is a matter of either reducing the amount of CO2 people put into the air, or putting some of that CO2 back into the earth.

“The first degree of warming doesn’t cost that much. We’ve had that one. The next degree costs more than the first one. The next degree costs more than that one.”

“As we raise the temperature going through decades and beyond, you start to get to the point where it’s hard to work outside in the tropics; you get to the point where our crops have trouble growing because they’re just too hot; you get to the point where you really worry about melting big chunks of ice that are sitting in Greenland and Antarctica and raising sea level a lot.”

“I am very worried that if we don’t respond, that we end up worse off,” he said. “Eventually the losers are our grandchildren and their grandchildren.”

    A delicate balance built up over a long time is being disturbed. We may not have all the science in place to link cause with effect, but a lot of records are being broken. We have a duty to the planet and to the generations to come.

      No, it isn't. The fact is that we have had extreme weather events like this for HUNDREDS of years in America.... the issue is that back in the day, people did not whine about the weather issues and prepared better for them.

        We've had weather on this planet for 4.5 billion years. Hot, cold, sea levels rising and falling by several hundred feet. Species arise, go extinct. No big deal. But it's a problem for HUMANS because we've delineated countries and property and farmland and we have a lot of very expensive infrastructure, in Galveston or Manhattan. If 20% of the cropland or real estate in the world becomes unusable, it will be a problem for you, personally.

    It's always absurd to me that we keep debating this. It's approaching ad nauseam.

    Let me make this extremely simple.

    I trust Scientist more then politicians to explain the mathematical relationships in the world and how they change over time.

    I look to Science to explain what is happen if anything, and I look to politicians to explain what are we going to do about it if anything.

    The short answer is this, regardless of the cause natural or unnatural things are changing. We can make preparations for the changes, or we can ignore them and continue to pay the price.

    Why are we not building more Sea Walls? Why are we not creating better flood control management? Why are we not making preparations for the changes that are coming regardless of why they are going to happen?

      The problem is that scientists are sometimes wrong. Maybe they don't properly interpret the data, maybe they omit some relevant data, maybe they just make wrong assumptions. Scientist used to think the world was flat and the sun revolved around the earth. Last year, we were told that 2013 would have a large number of hurricanes and those storms would be larger than in the past. However, 2013 was EXTREMELY quiet. If we can't predict seasonal storms with much repeatability, then how can we pretend to understand the complete global climate picture with such certainty. We should continue to gather data, make common sense changes, but not freak out over something we may have little control over. If we don't understand the true causes, then we are just doing a bunch of actions that may not address the problem at all. Meanwhile, I am paying several times more for light bulbs and have seen several increases in my power costs due to regulations that may or may not be valid.

        Crashman – you need to check on the validity of the 97% of scientists you mentioned. You'll find it's a lie – in fact if you have a serious look, you'll be horrified when you learn how the figure was derived, and how we are being misled.

    Of course records are broken every day. We have less than 200 years of temperature data, and it is questionable how accurate even that data Is. Could thermometers in 1814 accurately record to the 100th of a degree? How does anyone know if the models climatologists use to "adjust" for metro areas are 100% accurate. The earth is billions of years old, 200 years of data can, in no way, be considered statistically valid. The idea that CO2 is a greenhouse gas and therefore the temperature must be rising is akin to saying "I see you are eating a candy bar, candy causes obesity, therefore you are statistically certain to be obese".

      No Thermometers in 1814 could not be as accurate as today, but you know what there are ways to account for that in statistical modeling.

      Also with a big enough sample size, the central limit theory takes hold and gives you meaningful data. This is how BF was able to produce his farmers almanac with such good results in the 1700 hundreds. Repeated observation and data collection even if the data was not ideal.

The 97% scientist...BS has been debunked 100's of times, yet that is the Go to on the left.

      The claim that in the 70's that scientists were all talking about a coming ice age or global cooling is a complete myth. It is true there was some articles in Time magazine about a coming ice age, in 30,000 years. Which based on *normal* earth cycles, is still true. But, the fact that CO2 causes warming was known by scientists long before the 60's even if Time magazine did not.

        Not quite true. The hypothesis that increased CO2 could cause warming existed long ago, and many scientists still support it. However, the effect of CO2 is logarithmic. It's like painting a window black, and no light gets through. Give it another coat of paint, and it makes little difference. So, the effect of increased CO2 is very much in doubt.

        Now we come the the real question – the assumption is that increased temperature due to increased CO2 will result in positive feedback (eg more water vapour – the strongest greenhouse gas, causing more warming), which will dominate negative feedback (eg cloud cover – cooling). To date there is no evidence to support this hypothesis.

    Actually, the magnetic field of the sun has reversed recently, and this low gravitational pull holds back sun spots and solar flares, affecting the ionization of the upper atmosphere, leading to more cloud cover and cooling the earth. The current solar maximum 24 is the weakest in decades. Water vapor trapped in the stratosphere could not have any influence on the normal creation of clouds and precipitation/drought. It has always been the sun, and its solar output that warms and cools our planet, and always will.

    What we want now is politicians who pass laws raising energy prices, taxing "carbon" (emissions) these electric power plants give off, and raise money for cherished government programs. If the inactive sun continues the next four years, and we have colder winters, then that would offset any warmer summers, including the Arctic sea ice increasing, as it did this past year, and Antarctica having colder temperatures.

    Lost in the debate on climate change is the influential role of our sun, and is always man's "activities". Why is this?

      Let us not forget about the Pacific decadle oscillation. The deep sea currents help change weather patterns as well. As for CO2, it is a plant food. Other man made emissions are certainly harmful and should be reduced, but not at an extreme economical castrating rate. The sun is the primary source of heat for the earth, if CO2 traps heat in, must not it reflect heat from the sun back into space before it touches the ground? It is not a one way mirror and we must also not forget that the earth is round, so therefore infared has a higher chance of being reflected back into space due to the curvature of the earth.The most heat trapping component in the atmosphere is water vapor. That is the simple truth. It makes up 97% of the thermal cycle(From IPCC). Just look at a desert temperature swing from night and day and you will see what I mean. New studies into the solar cycle and the link to the cloud formation process have actually made a better link to climate change then any of the models that are currently used. We know the cosmic radiation helps in the creation of clouds and when the sun is very active with solar flares, it pushes more of the cosmic radiation away, thus less cloud coverage, more sun light reaching the ground, and high humidity stays due to lack of precipitation in the cloud cycle. That is warming the earth morer then us and yes I believe humans have contributed to the warming, but are we so egotistical to think we are responsible for it all? Waste your guilt on something better like overpopulation or world hunger. Those things we can quicker than this climate change conundrum.

    It is a cold wave. In January. In the middle of Winter.

    It neither proves nor disproves Climate Change theory. But, according to the IPCC, Winters are supposed to get shorter and milder, with less snowfall – i.e. many areas accustomed to getting snow would see milder winters with rain and less snow.(IPCC Group 2, 2001), So a cold snap breaking 20 year records would appear to buck that, but one harsh Winter means little (as does one mild winter). It's how the trend develops over decades that counts.

    Personally, I don't think enough is understood regarding all the complexities of climate to really know what it will do over time, other than change – because that's all it's ever done over millennia, change.

    Here we go, climate change (f/k/a/ global warming) is causing us to be colder and get more rain. This coming from the same "scientists" and weather forecasters that can't accurately tell us what the weather is going to be next week! Truth is, there have ALWAYS been cold snaps, floods, heat waves, earthquakes, hurricanes, rain, sunshine, and all the other natural phenomenon that gets attributed to climate change. The only difference now is that but for the past couple of decades news traveled very slowly, and we didn't hear about many things. Today, we know in a nanosecond what is happening on the other side of the globe. And this is magnified by the 24-hr news/entertainment channels looking for something to sensationalize so we'll watch it. Yes, the climate changes. I imagine it has always changed and always will change no matter what. Let's get over it and stop wasting money and government time on it!

    Of course its climate change due to global warming, its a fact that the global ocean conveyor current in the atlantic that brings warmer waters up from the equator has been slowing down and moving further south due to the waters in the arctic being desalinated by melting ice due to warning, temperatures in the arctic have gone up over 6 degrees on average higher than anywhere else. without this warm water the jet stream falls further south and bringing along with it the arctic air which is exactly what is happening, this is going to continue to get worse till one day temps will drop to 100 below zero and will last for weeks then months making life in the north eastern u.s. unliveable, this was all covered in the film "the Day After Tomorrow" go watch it again to see the future.

    Check NOAA’s info regarding the record high temps for this year and last:

    What I find curious is that there are many people who act as arm-chair climatologists in determining whether climate change is real, let alone who caused it. I do not know about you, but as an architect and not a structural engineer so I trust them to tell me the correct way to support roofs, floors, walls; A non-meteorologist/climatologist person should trust the scientists/climatologists/meteorologists who have all the data and can interpret it better. Overwhelming they believe in climate change and that humans are the cause.

    One final note, while we know the advantages (motives) of many of large (money) supporters against climate change, what do climatologists get out of warning us when they know the outcome is people yelling at them that they are wrong, having to pay more money (ex. carbon offsets and taxes) to help fight what they see are impending disaster for our collective humanity, and feeling like they are talking to a brick wall many times. This New Year should bring about new thoughts on how we as a collective world should work together for the best of all instead of our own selfish individual desires

    I don't know the science behind the conclusion for climate change nor do I want to get in to a debate about it. I do know that I believe in using scientific and technological advancement to better things. If you look and corporations, many of them in the US are installing newer more energy efficient systems and design. Why? Because it saves them money. Why do they recycle their waste? Because people will pay for those recyclables and it reduces the waste disposal costs by lessening the number of dumpster pulls they have to pay for. The finance departments in these companies know that if you invest the right capital it saves you money in the long run. These results are definite and measurable.

    Remember when you bought an 8 pack of glass soda bottles? Why don't we use glass anymore? because it's heavy. It costs a lot of energy and money to move something that's heavy. That's why we went to plastic bottles. We also prevented waste when we had to pay deposits on those bottles. Companies found out it's better to use less plastic in their packaging because they can tout that they use less, but it also costs less. It's always about the money.

    The next great wave of money savings will be when we start to design and retrofit residential living to more energy efficient systems and design. Pres Obama was well intentioned when he spent all that money after the recession started, but he did it all wrong. When we can show people the numbers to saving money by improving their living envelope then things will start to move.

    If you invested more money in the price of your house by installing more efficient systems, your mortgage payment would be a little higher, but you could deduct more of that mortgage interest on your taxes. On the flip side, you would be saving much more cash every month from lower utility costs to apply towards that mortgage.

    Finally, for me as a Christian, I believe that if God originally entrusted man to take care of his world, then if I have better options to take care of it, such as composting, recycling, and using clean energy to take care of it then I should absolutely do so. I would like all of the southern and country Republicans that love to showcase their Christianity to put up or shut up.

      Climate change is not some left-wing plot to tax people more or take away their freedom or kill capitalism. In fact, the new green energy revolution will revitalize our economy if we don't wait until it's too late. Powered by the meshing of renewable energy with Internet technology, it will give individuals more autonomy and free them from the monopoly of the big fossil fuel corporations and the crony capitalism that is robbing us of our democracy. This is something both liberals and conservatives can support.

      Solar and wind will allow individuals to produce their own green energy in their homes, offices and factories. This is not a pipe dream. It's already starting. Read the new book, The Third Industrial Revolution by Jeremy Rifkin, who is a senior lecturer at the University of Pennsylvania's prestigious Wharton School's Advanced Management Program. It will be real free-market capitalism.

Why would anyone completely trust scientists? Isn't this the group of people that once swore the world was flat any the universe revolved around the Earth?

    Back in the sixities, wasn't the fear about the coming ice age?

    Do we really have enough information to make a conclussion? Are we being intellectually honest with ourselves?

    Anyone that doesn't realize that the vast human species isn't influencing global climate change, is living in a fantasy... Since the Industrial Age humans have been spewing mass amounts of greenhouse gases that DO affect the climate. Most people are too obtuse to understand that it's not global warming, but rather an overall change in weather patterns – thus exacerbating the natural global weather cycle. Smoke a cigarette in a garbage bag and let me know how you feel afterwards… After reading some of these posts, it validates my opinion on our crummy educational system.

    My biggest problem with climate change (AGW) is there have been monumental swings in Earth's climate for millions of years. 15 thousand years ago during the last glacial maximum you had a mile of ice sheet over half of North America. 65 million years ago till roughly 35 million years ago the climate of what is now Maine was like what it's going to be today in Central Brazil. Now a large group of published and respected climatologists say that we have never warmed so quickly. That is absolutely unverifiable,dont get isnt!! The fact that they scream that it is should tip you off. There is actually strong evidence you had at least a 6-8 degree increase in world wide temps in just a few hundred years when the Laurentide ice sheet collapsed which was the end of the last glacial maximum.

    What the vast majority of people don't realize is we are in an ice age right now. We are in an interglacial cycle in between maximums.This current cycle of glacial maximums and minimums started roughly 1.3 million years ago. For large swaths of the Earth's climate history there was zero permanent ice cap at either pole. 65 million years ago the CO2 concentrations were over 800ppm,today they are 380-400ppm up from 320ppm 150 years ago. The Antarctic ice cap didn't start forming till roughly 35 million years ago when CO2 fell below 600ppm. In short my point is,until we can explain what caused the monumental climate swings when we couldn't help with any sort of climate forcing,it's wise to be a skeptic that the one degree of warming we have had since 1900 is our fault. Just be partial,do some research on your own,from reputable sources and studies. The information is out there,form your own opinion.

    "Record Low"? Using what sample size?

    Is it possible at all that these cyclic phenomena may have taken place multiple times in ancient eras well before records have been kept? No? Why not?

    Today is a year since the opening of the 12-12-12 portal and indeed many, many things have occurred behind the scenes which are still in fact hidden from your view. We want to give you a metaphor of what is occurring right now in the higher dimensions for you. Picture a beautiful field of flowers and trees all around, with grassy areas of sunlight and shade and the sun shining upon all. There are tables being set for a grand feast, decorations being put up, and many, many party planning activities are in process. Flowers are being planted in a most beautiful arrangement, fresh food and drink are being laid out, and there is a grand scene of preparation for a beautiful celebration for our earthen humans that will be commencing shortly. This beautiful celebration will be honoring the christed light within each one of you, as well as the principles of sharing, love, unity, harmony, abundance, peace, a merging with the higher dimensions, assistance from the galactic star nations who will also be attending the celebration, and many and all of the higher dimensional principles from which we operate in the angelic and higher dimensional realms. All of these principles will be celebrated during this joyous occasion. All beings on earth are invited to this feast and reunion of our galactic families with beings from your higher consciousness earthen communities, including you. We are showing the channel a vision of these beautiful celebration festivities which are being planned for you. Please take a moment to pause and tune in.

    We have never had cycles of CO2 in the atmosphere, at the levels it is at presently. Never. Ice core data, among other methods, confirms this.

    Familiarize yourself with what 99% of the world's climate scientists are saying, and stop exclusively listening to the 1% that are telling you what you want to hear – or even worse, completely scientifically unqualified tools with vested economic or political interests in telling you everything is just fine, or that the "science is still out".

    As the climate scientist in this article points out – the reality of climate change has absolutely nothing to do with personal politics. Or it didn't, until political operatives decided to treat it as yet another front in the "culture war". These are the same charlatans that try to convince everyone there's a "war on Christmas" ever year.

      In regards to your "99 percent of scientists" claim: First, it's 97%. Second: One of the main scientific proponents of man-made climate change conducted an analysis of all peer-reviewed research on the subject. He only found that 34% of climatologists came to a conclusion on the subject. Of that 34%, 97% endorsed that idea of anthropogenic (man-made) global warming. So everyone reports this as though 97% of scientists agree, while in reality only 34% of scientists researching the subject have reached a firm conclusion on AGW. Link to the actual paper here:

        I'll take your correction on the 97%.

        However, that abstract says the 66.4% of papers didn't express a position on AGW – not that there was insufficient evidence to. There are thousands of papers on climate change, that have nothing to do with deducing root cause, and thus announcing a position is unnecessary. You're conflating that with the climate scientists involved with those papers not personally reaching a conclusion on the question altogether. As the abstract notes, they just did a broad search for any articles on global climate change – not specifically ones addressing whether AGW is real.

        Of the ones that do address that question, as you say, there is a 97% consensus. And the conclusion of the abstract you link to: "Our analysis indicates that the number of papers rejecting the consensus on AGW is a vanishingly small proportion of the published research."

    First, a bit on the credibility of "the science is undeniable." Remember how "97% of scientists support global warming"? One of the main scientific proponents of man-made climate change conducted an analysis of all peer-reviewed research on the subject. He only found that 34% of climatologists came to a conclusion on the subject. Of that 34%, 97% endorsed that idea of anthropogenic (man-made) global warming.

    Second, while everyone agrees that CO2 is a greenhouse gas, there is a big difference is showing that it can trap heat in a test tube vs. impacting the atmosphere when the increase is about 2 parts per million since the industrial age. For the author to claim that anyone who doubts the impact of this increase somehow doesn't believe that CO2 is a greenhouse gas is nothing more than misdirection, similar to the 97% claim.

        My point is that the media narrative over and over is that "97% of scientists support the premise of man made global warming." The author of this paper himself, while providing the clarification in his own paper, leaves it out when doing media interviews. Then people commenting here repeat without understanding that the whole scientific community does not have a firm conclusion on AGW. While you're correct that a very small portion take a firm position on discounting AGW, that's whole point. Most of the community does not feel the data is conclusive enough to form a firm opinion. The climatologists going out on a limb to make it a firm certainty (34%), in my opinion, are the ones that wish to push this as a political issue.

        To your point, many of the 66% of the papers did not feel a need to cite a cause for climate change. But the author of this is paper is very pro-AGW and this was the best he could come up with. Your own initial comment throws around that 97% stat when you don't really know what percentage of the other 2 thirds really support your theory or not.

    I would like to see the climate change discussion placed into a broader context. There have been numerous periods of temperatures rising and falling over Earths's geologic record. This discussion should be framed into Earth's historic past to see if we are repeating the past are diverting from it. There have been five known ice ages in the Earth's history. Within each of the 5 recorded ice ages there are periods of more severe glacial conditions and more temperate referred to as glacial periods (cooling) and interglacial periods (warming). So, are we experiencing a typical interglacial period event or not? Please recall, our far distant predecessors did not generate high volumes of green house gases (unless they built too many fires).

      This interglacial, the Holocene, is a bit on the cool side, and thus far, of average length. The previous, the Emian (sp?) was slightly warmer, with hippos swimming in the Thames. This cycle of warmth within the Holocene is slightly cooler than the last warm period, the Medieval Warm Period, and perhaps about the same as the Roman Warm Period. Thus far, it is significantly shorter than the last warm periods, which ran for ~400 years each.

      It depends on the size of the volcanic eruptions. For example, the 1991 Mount Pinatubo eruption is believed to have reduced global temperatures buy 0.5 °C (0.9 °F) for approximately 2 to 3 years. The 1883 Krakatoa explosion is believed to have cooled the earth for 3 to 4 years. It's the amount(volume) of airborne ash and it's distribution that can significantly cool the earth.

The fact is the phenomenon is fact the messaging flawed, the motivations of all involved are conflicted with the message delivery for such an important issue we must take pause and analyze the ramifications of everything involved, the Earth has a finite atmosphere measured in cubic meters of those cubic meters there is point when contaminants out number the beneficial qualities namely when people can breathe comfortably. The global warming issue concerns when the objective of breathing comfortably is no longer met to which I attest that time has arrived!!! We can no longer pretend that our filth entering the air we breathe is tolerable, in fact during the last 12 hours I can attest that it is not. At 430 this morning my smoke detectors activated in my home, totally electric, no sources of flame nor contaminants in fact I have 20 high capacity air purifiers running full speed 24/7 but to no avail, the inversion over road all my safeguards to which I have no remedies nor defenses!!!! The only solution for myself and all of our nation is to stop the pollution before its too late because Wall Street cares nothing about people only profits!!! We must act soon or we will never act again!!!

      This is not about some foolish nonsense like a "message" - it is about the fact that many rich and powerful people do not like what the real science says - so they have worked hard to make as many as possible confused.

      The truth is that Weather Science has always been difficult and uncertain. We know a tremendous amount compared to, say, twenty years ago, but no matter how you slice it weather is a Dynamical System - it cannot be easily predicted with great accuracy. That uncertainty bothers some people, who would rather trust in absolutes - even absolutes that are wrong.

    So let me get this straight. If we were having record high temps right now, the scientists would say its a clear sign of global warming, but when we have record cold temps, they call it an anomaly and say it is not related to global warming. That kind of sounds like ..if the weather helps our argument, use it...if it doesnt, then ignore it

    • Edwin

      Sonny, the reason it doesn't make sense to you is because you don't want to believe it. Here are some facts:

      1) the average world temperature has risen over the last century. This is not a simple linear trend - it has jumps and setbacks, like all REAL data does. But the trend is unmistakable, and the pattern is steeper than linear.

      2) even as bitterly cold as this last week has been in the United States, there were very few record colds set here. There have been, actually, very few record colds set in the last ten years. Lots of record highs, very few record lows. If temperatures were NOT increasing, that would not be happening.

      3) pushing the earth's temperature higher upsets the overall weather system. Imagine a large pendulum. Push the arm higher (with warming) and what happens? The hots are hotter, and then the pendulum swings back again, causing dramatic cold spells. Earth weather is what mathematicians call a "dynamical system" - a part of Chaos Theory. For centuries we were in a relatively stable period, but we have pushed ourselves out of that period. You only have to look at the other planets in this solar system to see how TRULY crazy weather patterns can be... we can look forward to that in the future.

      4) to reiterate, the extreme cold temperatures we have had recently are unusual but actually NOT records, except for a tiny few number of places. On the other hand, Australia DID have many record highs. Remember: GLOBAL warming is about the average temperature over the ENTIRE GLOBE, not just the United States. Americans may think of ourselves as special, but we *are* only *part* of the globe.

    In looking at some of the comments here, it would seem that some of you would have us blindly accept Anthropogenic Climate Change theory without question, or without considering the arguments of the Climatologists who happen to be skeptical of the link to human C02 emissions, as well as ignore the fact that the climate has warmed at a much lesser degree than all the models based on Anthropogenic Climate Change had predicted.
    That's not to say that there's no human influence behind the warming that has been observed over the past several decades, but there are some valid questions regarding what the models have led us to believe vs. what is actually being observed.

    In a paper just published online a few days ago in the most highly-respected peer-reviewed science journal in the world, Nature, new data showed that climate change is occurring faster than projected and by 2020 the tropics are expected to be "unlivable" and we'll be next, about 2045, assuming we are stupid enough to keep burning fossil fuels. By 2100 global temps are predicted to be 4C higher than today, which means most species, including humans, would not be able to survive.

    The global climate is rising, this can't be disputed. But don't think that scientific information from just the last 150 years is the end all be all. In fact, it's really only a drop of rain from a hurricane. The earth is something like 4.5 billion years old. Remember, at one time, there were no cars, factories or millions of cows and yet the earth was so hot it supported the lives of millions of giant lizards. Was it that 200-500 million years ago there was so much giant dinosaur poop that the CO2 levels were off the chart and everywhere you turned it was a jungle? Thankfully that comet hit us and brought the world back into balance.

    If we have a heat wave...evidence of global warming. If we have a cold snap....evidence of global warming.

    Sorry, but the way science works isn't independence (although that is what they like to think), it is following the herd. If you step out of that mold, you don't get funding. Thus if the big labs and research centers said the sky is green, you better come up with research questions that will investigate why the sky is green (even though your evidence may not back that up).

    E.g. Over the eons there are cyclical changes in weather patterns, but because it is "cool" to jump on the bandwagon, we will say it is created by humans in this case. Even though the trend does follow cyclical patterns before humans were around to fart enough to change the environment.
    Evidence has shown over the past 14 years 6 of them have been hotter than usual, but then again 5 of them have been colder than normal and the rest just normal. It all averages out in the end.
    Ice sheets in both the Arctic and Antarctic are expanding (e.g. Arctic expanded by 1 million square miles). Then you get the holly wood types that get stuck in the ice that wasn't supposed to be there, but I guess that is global warming.

    people like to talk about CO2 and its contribution. THis is an issue I have in many of the physiology classes I teach. When I ask "what percentage of the atmosphere is made up of CO2" I usually get responses in whole %. Fact is CO2 is a trace gas. In total it is about 0.038%. The rise everyone talks about is from 0,035%, which in the grand scheme of things is insignificant. The shocking graph that is always shown in the media is skewed. Look at the y axis and see its #s. it doesn't start off at 0. THe reasons is purely for shock effect. Then you get the people that say it is a toxic or unnecessary gas. Believe it or not, but your body's ability to breath depends on CO2, same thing for plant's survival. It is these liberal types that will go around crying the sky is falling that really need to learn the science and how science research works (I am a prof btw), before blowing their lids on how the end is nigh.

    The funny thing in all of this, is that most people who support anthropogenic or carbon dioxide induced climate change can not answer the following very important questions (the correct answers will enlighten as to why these questions are important).
    1. Please list the top 3 greenhouse gasses in order of decreasing effect (could be considered a two part question because the order is also significant).
    2. By what physical process/method does heat leave the earth? Remember, the earth and its atmosphere is in the vacuum of space, or effectively a thermos bottle.
    3. How does carbon dioxide act as a greenhouse gas (describe actual physical process). Gore's acts like a blanket gives you an instant F – because it is incorrect, quite misleading and means that the answer is not your own.
    4. Which greenhouse gas is not currently correctly/completely modeled in the simulations and why?
    5. Why do cosmic rays have a potential effect on climate and climate modeling? How does the solar wind and Van-Allan belts play into this. What is recently starting to happen to the earth and has occurred in the past and how does this play into the Van Allan Belts?
    6. Which two 'odd' behaviors of water effect the climate?
    7. Approximately what percentage of the atmosphere is carbon dioxide presently? What percentage is oxygen?

    - got more, but this enough for some thinking.

    Yes it is climate change related. We've been told an Orwellian lie about carbon dioxide and methane; they both cause global cooling, and the so call radiative forcing they are deem responsible for is minus a few facts as well. The heat is forced into water vapor; it is the only non diabatic gas capable of holding heat that effects the atmosphere.

    The oil and gas industry is experimenting with methane hydrate harvesting in the Arctic and have been doing so since 2003. The experiments have failed to capture much gas and have released a tremendous amount of heat and methane to the atmosphere. The ice in the Arctic only started melting after the 2003 experiments. Methane hydrate is capable of removing and or releasing up to 400 degree F all at once. Methane oxidizes to CO2. Excess CO2 is putting water vapor higher in the atmosphere where it does not belong and methane is right next to it, forming its hydrate in the sky .That is why hail is getting bigger. Carbon dioxide goes into the water. Carbon saturated water causes global cooling. It does not freeze until it reaches about 22. F The Antarctic is cold enough to get it there. Once there, it is 60 times stronger than regular ice. Winds in the east Antarctic are katabatic and blow from the top of the land mass down to the sea. away from land. January is the warmest month of the year. December is the early summer. NASA recorded the lowest temperature on Earth in December, in the summer, not the winter. A vortex is created by heat wrapping around cold. All the moisture going over the east coast is going to the Arctic and creating incredible blizzards in Nunavut. When a scientist tells you that they are stuck and the ice is growing in the middle of the summer, you need to verify that. Call NASA and NOAA and get the proof as to where the ice is was blown from. Go to the library and input all the scientists names on the ships to see what they have written about before and who they wrote it for.
    Finally global warming is being brought to you from the deep earth. We are being steamed from below by radiant heat from dissociating hydrates, for a good part in our seas. Methane is pouring into our seas.

    There are 7 billion humans, every single one seeking a better life. There are not a one politician in any democratic system that will survive the Next election by woving to restrict possibilities for a better life. Hence global warming is unstoppable until such time that the effect has diminished the population to sustainable Levels. Rather bleak, but probably quite a fundamental observation. The climate change debates are all acting like a smoke screen over this observation, whereas the real question is how to reduce populations to sustanable Levels and at the same time maintain the possibilities for a better life.

Why don't we colonize the deserts (Sahara) or the poles (water problem solved straight away) where animal and vegetation impact derived from such action would be minimal, and then we can have all the Earth's forests full of animal and plant species.

    I'm deff no expert but it has bothered me that it is being said we have caused this with the use of cars etc but did the glaciers not start retreating long before these things which to me leads me to believe this is just a natural cycle of our planet

    We've heard a whole lot about how this polar vortex is affecting people – and with good reason.

    But hasn't anybody considered what happened to the polar regions themselves when their normal polar vortex decided to take a walk south? Has the air over the poles remained as cold as normal? Doubtful. So it probably warmed up, and that ought to be of great concern, since our polar ice, at both poles, seems to be shrinking alarmingly.

    Anybody know the scoop about the polar weather these last few days? I think that is of some importance.

    Sometimes I think people like you are beyond help. I have no kids so for me this is all a game anyway, I'll never see the worst outcome. CO2 levels have risen to almost 400 parts per million and are continuing to increase at a rate that is not seen in nature. Last time we had that much CO2 in the atmosphere was 15 million years ago and sea levels were 75-120 feet above where they are now. It really doesn't matter what BS conspiracy theory you want to believe, the die is cast and your ancestors will live in a very very different world. Laugh as much as you like. No decent scientist has a significantly dissenting view, unless the Koch brothers are paying for it. What do people get out of lying about facts? Short term financial gain I guess. But I wonder what their long term plans are. I bet they have a house well above sea level.

    Climate change is not some left-wing plot to tax people more or take away their freedom or kill capitalism. In fact, the new green energy revolution will revitalize our economy if we don't wait until it's too late. Powered by the meshing of renewable energy with Internet technology, it will give individuals more autonomy and free them from the monopoly of the big fossil fuel corporations and the crony capitalism that is robbing us of our democracy. This is something both liberals and conservatives can support.

    Solar and wind will allow individuals to produce their own green energy in their homes, offices and factories. This is not a pipe dream. It's already starting. Read the new book, The Third Industrial Revolution by Jeremy Rifkin, who is a senior lecturer at the University of Pennsylvania's prestigious Wharton School's Advanced Management Program. It will be real free-market capitalism.

    The global temperature can be calculated to within a few hundredths of a degree. It isn't rocket science. You can also calculate the annual variation. Not rocket science. You then look at 2013 temp, and 1950s temperatures and you get something called a p value. That value is the likelihood that is is just coincidence. In the case of global warming, the p is really really small. That is how you prove an effect is real.

    You're right that the vernacular shifted from "global warming" to "climate change," but you're mistaken as to why. The shift was to try and help people like you, who could not think your way out of a paper bag if your life depended on it. See, neanderthals, like yourself, have a tendency to hear "global warming," wait for a cold day, and then say "hey, look! It's cold out. Global warming must be a myth!"

    I'll try to explain so that your tiny brain can process the information, but I'd advise you to read slowly. The "warming" part of global warming refers to the melting of the polar ice caps, which causes climate change that results in more extreme weather (of both the hot and cold variety).

    I don't actually expect you to understand any of this, because it honestly isn't that complicated and, if you were capable, you would have figured it out already.

    Actually, Helmut, "global warming" was always something of a misnomer, and it is too bad that it caught on the way it did. "Climate change" – particularly anthropogenic climate change (ACC); i.e., climate change that is AFFECTED BY (not "caused by") human activity – is about temperature and weather EXTREMES – in both directions. "Global warming" is the TREND; i.e., DESPITE some periods of colder temps, OVERALL temperatures are going up. And the science on THAT is as slid as the science on evolution or gravity – claims of the science-denying "right" notwithstanding.

    The gold standard for what Earth's average temperature is doing are glaciers. Anybody who takes about five minutes to Google some photographs and satellite imagery of glaciers will be able to plainly see that glaciers worldwide have steadily been reduced in size from year to year and significantly reduced in size since the earliest photographs taken during the 1800's. It isn't rocket science. Steady global temperatures result in glacial stability. Colder average global temperatures produce glacial expansion. Warmer average global temperatures reduce glaciers.

    'They also have no answer is to why carbon levels were twice as high a thousands of years ago and cant draw any conclusions to climate change.'
    Why do you think they have no answer to past varying levels? You need to do more research on that, especially if you think levels were twice as high thousands of years ago.

    'They say the ice in the artic is melting, yet fail to mention the record ice levels at the south pole'
    No they arent record levels, they are record levels of GROWTH but are still below the norm. Plus one is ice surrounded by water, the other is ice surrounded by land. You get variations to that.

    A bit on the credibility of "the science is undeniable." Remember how "97% of scientists support global warming"? One of the main scientific proponents of man-made climate change conducted an analysis of all peer-reviewed research on the subject. He only found that 34% of climatologists came to a conclusion on the subject. Of that 34%, 97% endorsed that idea of anthropogenic (man-made) global warming. So everyone reports this as though 97% of scientists agree, while in reality only 34% of scientists researching the subject have reached a firm conclusion on AGW. Link to the actual paper here:

    Do you believe it when 'scientists' tell you that volcanic activity caused climate change in the past? Regardless, go find the numbers yourself, so you believe those numbers, regarding the amount (tons) of guk spewed into the atmosphere by volcanos, the big ones, that supposedly caused climate change. Then go find the numbers (tons) of guk spewed into the air by human activity every year. What you find is that by burning all those fossil fuels as rapidly as we are, we are putting just as much (actually more) guk in the air as those climate-changing-volcanoes did. 1+1=2. Go get the numbers for yourself – that's what the internet search engines are for, and, check multiple sources. BTW, our far distance ancesters numbered in the millions, or less, we are 7.4 billion, and, they didn't burn fossil fules like we do, so , uh, holy kripes, find a brain.

    The first article of this nature, I went down the comment board provided by 'disqus', and it was horrid to see all the varying levels of stupid...

    To agree with you folks – yes, these people on here denying climate change and saying 'it's just a natural process' – you are partly right and partly wrong, and to those people that are saying the definitive facts about climate change – at least you are not altogether wrong, but then again, we shouldn't blast those who 'don't have a brain, i.e. the mental capacity to figure it out'...

    Climate change, i.e. global warming has served as a warning 'red flag' from scientists for several decades now. Still, big money, big media, big politics, and other influences have decived the rest of you into thinking this is somehow a 'myth'. If that includes you, I can also guess that you are likely to 'believe in the free market', 'believe in creationinsm' – which started out ok saying that there might have been a god originally, in the first universe, but then derails at 'humans lived with dinosaurs 6,000 years ago and that is the age of the earth'. You are also likely to not believe or accept scientific facts – mostly because you cannot descern the difference between a fact and an opinion (an opinion is supposed to be a conclusion derived from facts and observations – now, that is the exact reason scientists say 'mostly certain' instead of 'exact', because we are only deriving the most accurate predictions from the observations we have made, with of course the smallest degree of error and the widest degree of acceptance...)

    That said, yes, climate change is a valid conclusion derived from the facts behind it.

    Those of you that deny it, consider that in the past we had this happen before. In recorded history (ice sheet studies of CO2 levels), we can see that at one point CO2 reached a pretty high level, and it resulted in the last ice-age. Now, ice-ages didn't always use to be the case. During the time of the dinosaurs, there were no such ice-ages, even though the earth likely started out its existence, before being habitable by life, as a big snow ball. Getting back to the point, the events leading up to one such ice-age resulted in a complete elimination of the fossil record. That was a bigger planetary die-off than the demise of the dinosaurs, I am afraid...

    Now we are at a point where we are at a CO2 level larger than any in history that we have been able to record. Always in the past, a certain level of CO2 resulted in an ice age. We are hoping that happens again, but alas! These ice-ages took thousands of years to develop. We are already past the highest recorded CO2 level. This means the following: Who the heck knows what will be the result of this? We are making a correct assumption on more severe weather extremes and strange weather patterns, more planetary disruption and natural disaster.

    The reason this is so important for the rest of you to understand is simple: We are exacerbating the 'natural climate change' into 'rapid climate chaos', basically. If you can follow me here, what it means is that the only thing we can now hope to do is somehow artificially reduce harmful greenhouse gases or accept the consequences of inaction – a planetary reset (in this please google 'permian-triassic extinction wikipedia' and you'll see how similar this event is to climate change today), meaning if you think you can just leave something behind, it won't be there 10mln years from now.

    Ignoring climate change will be the end of the earth (at least as humans know it), and will be the demise of most life on earth, and provided we have arrived well beyond any recorded Co2 levels, we may actually destroy life on the surface of the earth for good this time, unless we do, indeed, die off as humans, giving at least species found in deep oceans a chance to survive (I don't know if anything will survive this – in the past it just wasn't 'severe enough', and was largely due to 'natural means'. The difference today is 'artificial means' and 'well beyond anything the earth has ever been through' – I hope your ignorance doesn't result in a dead, radiation-pounded rock much like mars..)

    I would suggest to those of you who are aware of our 'situation', it is insane (as defined by Einstein), to continue to propose we simply stop polluting – that has been a failure of a proposal ever since global warming was discovered. Instead, I would suggest we move towards artificially lowering the greenhouse gas levels in the atmosphere – because quite frankly, you all should know by now if we do nothing still, we're pretty screwed....

    It was 97% and that survey has been debunked 100 times, so please don't use that as a source: Based on our abstract ratings, we found that just over 4,000 papers took a position on the cause of global warming, 97.1% of which endorsed human-caused global warming. In the scientist self-ratings, nearly 1,400 papers were rated as taking a position, 97.2% of which endorsed human-caused global warming. Many papers captured in our literature search simply investigated an issue related to climate change without taking a position on its cause.

    So they took 4000 papers written on Global Warning, which they have since changed the name, and 97% leaned toward humans having something to do with it. Here is what you don't get. You can not prove a negatvie, so you would have to write papers disproving everything else

    The 97% figure you cite is used in reference to the consensus that climate change is occurring, not that it is caused by humans. You can't conflate the two, although there is growing consensus on the latter.

    citing wikipedia, at least somewhat more credible than your article:

    "The scientific opinion on climate change is that the Earth's climate system is unequivocally warming, and it is extremely likely (at least 95% probability) that humans are causing most of it through activities that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning fossil fuels. In addition, it is likely that some potential further greenhouse gas warming has been offset by increased aerosols.[1][2][3][4] This scientific consensus is expressed in synthesis reports, by scientific bodies of national or international standing, and by surveys of opinion among climate scientists. Individual scientists, universities, and laboratories contribute to the overall scientific opinion via their peer-reviewed publications, and the areas of collective agreement and relative certainty are summarised in these high level reports and surveys.

    National and international science academies and scientific societies have assessed current scientific opinion on climate change. These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change (IPCC), summarized below:

    Warming of the climate system is unequivocal, as evidenced by increases in global average air and ocean temperatures, the widespread melting of snow and ice, and rising global average sea level.[5]
    Most of the global warming since the mid-20th century is very likely due to human activities.[6]
    "Benefits and costs of climate change for [human] society will vary widely by location and scale.[7] Some of the effects in temperate and polar regions will be positive and others elsewhere will be negative.[7] Overall, net effects are more likely to be strongly negative with larger or more rapid warming."[7]
    "[...] the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time"[8]
    "The resilience of many ecosystems is likely to be exceeded this century by an unprecedented combination of climate change, associated disturbances (e.g. flooding, drought, wildfire, insects, ocean acidification) and other global change drivers (e.g. land-use change, pollution, fragmentation of natural systems, over-exploitation of resources)"[9]

    No scientific body of national or international standing maintains a formal opinion dissenting from any of these main points; the last was the American Association of Petroleum Geologists,[10] which in 2007[11] updated its 1999 statement rejecting the likelihood of human influence on recent climate with its current non-committal position.[12] Some other organizations, primarily those focusing on geology, also hold non-committal positions."

    Strike that - ice levels in Antarctica are high, as predicted in many climate models. It's the Arctic ice that poses the problem because it rests on rock and adds to the volume of water in the oceans as it melts. It also dilutes the salinity of the oceans, thereby changing the density and depth of warmer and cooler water, and thus the circulation of the currents. This is what affects climate patterns.

    Venice is not being inundated by rising sea levels – Venice is actually sinking – check it out. This shows the hypocrisy of the Global Warming alarmists when they use photos of the flooded St Mark's Plaza in their propaganda.

    I have no time for anyone who feels the need to toss around ad hominems.

    Early scientists were routinely burned at the stake by the church. Galileo would have been too if he hadn't agreed to renounce all his evidence. He got by with life imprisonment. His colleague Bruno, was burned.
