Science Seat: Meet a climate change scientist

By Zaina Adamu, CNN

Editor's note: The Science Seat is a feature in which CNN Light Years sits down with movers and shakers from many different areas of scientific exploration. This is the third installment.

Thousands of families were left devastated when Superstorm Sandy destroyed their homes in October. When it comes to these extreme climate events, according to Chris Field, founding director of the Carnegie Institution's Department of Global Ecology, the worst is yet to come.

Field is also a professor of biology and environmental earth system science at Stanford University and a member of the Intergovernmental Panel of Climate Change delegation that won the 2007 Nobel Peace Prize. He holds a doctorate from Stanford University.

CNN Light Years spoke with Field before he headed to Boston for the recent American Association for the Advancement of Science conference. Here is a transcript, edited for brevity and clarity:

CNN: When you were a kid, did you see yourself getting into biology? If not, what did you see yourself doing?

Field: I’ve always been interested in the outdoors, and I’ve always been interested in nature. When I was about to graduate, I didn’t know if the best way to be involved with nature was from an artistic, social science or a bacheloral science perspective. But what I discovered is that the approach that I was best at and comfortable with was in the natural science perspective.

CNN: Where did your passion for climate change come from?

Field: Well, I think that - and this could be the case for most scientists studying nature over the last few decades - the importance of climate change has emerged gradually from our observations, but I think almost everyone has really seen the world changing around them. And the more I learn, the more I got an appreciation about how important the topic was and how scientific information was a critical part of the portfolio that would allow us to take action.

CNNBack in 1984 when you began at Carnegie’s Institution for Science, climate change was not as popular a topic as it is now. Why is that?

Climate change is something that we have been able to put the pieces together to relatively slowly.

One thing that is fascinating is that if we look back at the historical roots of our understanding of the way climate works and the way humans might change it, those roots go back very deeply. And some of the key insights trace back to the late 19th century. So that’s a long time from when we realized how pervasive the human actions and the human impacts of climate were. And it really wasn’t until the late 1980s and the early 1990s that we began to assemble a comprehensive scientific picture of the importance of climate change.

CNN: There are some who suggest that global warming is a myth. What do you say to people who think that?

Field: I think that there are important things that people need to understand. The scientific roots of understanding climate change goes back more than 100 years.

There was a brilliant Swedish chemist named (Svante) Arrhenius who published a paper in 1896 based on his measurements of how much energy carbon dioxide absorbed. Simply based on his observations on the absorptions of energy by carbon dioxide, he was able to come up with a relatively accurate estimate of how much the climate might change by the doubling of CO2.

Part of the reason why it is important to look back to Arrhenius is because we can really understand in great agonizing detail how the physics of heat absorption by carbon dioxide works and we can understand how that translates to our warmer planet. The understanding of the physics that was well-established more than 100 years ago is, of course, the core foundation on which the modern understanding of climate has been built.

The other thing that people need to understand is that much of our understanding of climate change and much of the foundations for our protection of the world in the future is not based on climate models, it is based on observation.

CNN: What is some of the research you’ve done and what are you working on now?

Field: For many years, my interest has been in the study of how climate change impacts ecosystems, particularly, for two reasons. One of the reasons is that humans rely on nature for a lot of important reasons.  Nature provides climate regulations, water purification. Climate has a real responsibility to try and protect the natural world.

The other reason why I have been interested in studying nature is that there is critical feedback where naturally, systems could either amplify or suppress the human actions that cause climate change. A good example of that is for every ton of carbon dioxide that we release into the atmosphere, only about a half a ton stays there. And the other half is stored (at least temporarily) into the oceans, into ecosystems, forestry and other plants. I’ve been really interested in the long run where we will continue to see a giant subsidy from nature in the future.

My studies have been experimental ones where we take ecosystems and we artificially increase the temperature, change the composition of the atmosphere and just see how the plants, animals and microbes operate under these simulated conditions. I’ve also done studies based of the analysis of satellite data, trying to infer what is happening on a global scale.

CNN: Do you believe that human beings contribute to climate change or do you believe that climate change is a natural part of the way the world works?

Field: It is extremely important for people to understand that as a scientist, I believe at looking at the evidence and try to understand what the evidence is telling me. And the evidence that humans are contributing to climate change is almost beyond dispute at this point. The evidence is overwhelming with the climate system changing. The fact that humans are the drivers by far makes it the most attractive explanation based on the evidence — not based on what I believe — but based on what the evidence says.

CNN: If we (humans) continue down the same path we are on regarding our contribution to global warming, what changes do you foresee happening to the Earth?

Field: I think what we are seeing now is that there are already impacts of climate change already occurring. We have already seen extremely hot conditions, heat waves, we’ve seen flooding. We’ve seen a clear increase in the number of events like high sea levels that caused Sandy.

The evidence of linkage that cause these things are pretty clear. It is also clear that as we move forward, much of what we will see will be a change in the frequency, the intensity and the duration of these types of extreme events. Climate change is not going to be about a perception about how the average [temperature] has changed. The most important impact that I believe [will happen] when it comes to climate is more extreme conditions.

  2. Arno Arrak

    I quote:

    "...scientific roots of understanding climate change goes back more than 100 years.... There was a brilliant Swedish chemist named (Svante) Arrhenius who published a paper in 1896 based on his measurements of how much energy carbon dioxide absorbed. Simply based on his observations on the absorptions of energy by carbon dioxide, he was able to come up with a relatively accurate estimate of how much the climate might change by the doubling of CO2."

    This is only a half-truth. They want us to think that they are using Arrhenius theory when in fact Arrhenius theory will only give a CO2 doubling temperature of 1.1 degrees Celsius. This is not enough to scare anyone. IPCC needs some angle to jack it up so that they can claim "dangerous" greenhouse warming ahead. For that reason they bring in water vapor, another greenhouse gas, and claim that it will raise the Arrhenius warming up to more dangerous levels. It works like this. First, carbon dioxide warms the atmosphere. Warm air can hold more water vapor than cool air does and the greenhouse effect of this additional water vapor gets added to the original warming from carbon dioxide. This way the total warming becomes a factor of three or more higher than simple Arrhenius warming will give. And this is how predictions of dangerous warming ahead are cooked up. Positive water vapor feedback is what they call it. But one of its predictiobs is an increase of atmospheric water vapor with time. And satellites cannot see that. But that is not the worst problem they have. Ferenc Miskolczi measured atmospheric absorption of infrared radiation over time by using NOAA's weather balloon database. It has data going back to 1948. He found that atmospheric absorption of infrared radiation was constant for 61 years while carbon di0xide at the same time increased by 21.6 percent. According to IPCC the added carbon dioxide should have shown absorption but it did not. So what happened? It is impossible to stop absorption because that would violate the laws of physics. It turns out that when several greenhouse gases, say carbon dioxide and water vapor, simultaneously absorb radiation an optimum atmospheric window for absorption is established. If one gas, say carbon dioxide, increases and causes extra absorption, the other gas must decrease to make up for that. What happened with Miskolczi's measurements is that as carbon dioxide increased over time the amount of water vapor diminished to make up for this. As a result, total absorption by the atmosphere as a whole did not change. This, in effect, is negative water vapor feedback, the exact opposite of positive water vapor feedback that IPCC uses. As a result, all their predictions are far off the mark. For example, in 2007 they predicted that twentieth century warming shall be at the rate of 0.2 degrees Celsius per decade. We are now in the second decade of this century and there is no sign whatsoever of this predicted warming. There has actually been no warming for the last 17 years as Pachauri of the IPCC himself admits. Their greenhouse theory that predicted this warming is simply wrong and belongs in the trash heap of history. Phlogiston, the other wrong theory of warming, is waiting for it there.

    I love the way so many people who claim to have done so much research and are convinced that we are destroying this planet fail to mention that Mars is warming too. Or is that happening because of the big oil companies?

      Again, please name your source. Also note that the environmentalist movement predicted these same climate reactions due to fossil fuel burning, 30 years ago. I know because I am an environmentalist and have been since then. But the deniers are now coming up with these sidebars like Mars is heating too. Please explain how we get that information since we have not been tracking the temperatures on Mars since probably quite recently.

      Haven't we been through this before. Population growth is not the most urgent matter. The places with low population growth use the lion's share of the resources and emit most of the poisons and emissions. The worse offenders are probably people like you though this is based on my assumption that you are not aware of your carbon and water footprint.

    I ain't buying the hype. A single large volcanic eruption launches more greenhouse gases into the atmosphere than the amount generated by all of humanity during it's entire history. And we have way more than just a single volcanic eruption worldwide each year.

    February 25, 2013 at 10:28 am |
    • DMW

      Name your source that we get as much in a single volcanic eruption please.

      February 25, 2013 at 12:30 pm |
    • Naaaaaa

      Opposite, WE put out more air pollution EVERYDAY than a volcano. THAT means 365 "volcano's" a year, EVERY YEAR.
      NOW do you understand why this IS important?

      February 25, 2013 at 2:37 pm |
      • eromdettimo

        Like your response to person and his volcano assertion that volcanos put more pollution in the atmosphere than climate change factors. It is a rather odd statement he makes, of course, esp. w/o citation. I've been watching climate change happening since before the term was heard–I was amongst a group of Friends, who, in 1974 protested in Philadelphia that the area's air inversion was caused by cars. We were arrested for stopping cars with our sit-down in the street. It was climate change. All I knew was that cars were damaging the air we breathe. Assertions that the layman can't see it without scientific protocols is wrong-headed. When I see my perennials bloom a month early, it's happening. Thanks.

    • CTed

      USGS begs to differ. We put out more carbon every year than a Mt St Helens like event. We put out more each year than all the volcanic activity combined. If we had a massive eruption every year on top of the normal eruptions (like the constant eruption of Kilauea) it might get closer but we put an order of magnitude more carbon into the air than volcanoes do.

    Well, the problem here is we have not got anything that can replace the oil we use to power our modern world. So unless about 6 billion of us die off, nothing will change or can change, it's just the way it is. Enjoy it while it lasts.

      This is bunk. We've got more than enough clean, renewable energy and if we conserved the waste that we do, we'd be rolling in energy. We have tried nothing; we haven't improved our public transit which would leave cities freer of the noise and pollution of cars; we haven't adjusted the traffic light changes which must waste tons upon tons of energy for nothing for sitting there idling (has anyone else noticed this?); the wasted energy from droughts and open doors and windows while heating or cooling is on; street lights on during the day and waste in dwellings and commercial buildings. We waste water for fracking and nuclear but water is the scarcest resource not energy. Energy is abundant. We have energy from the sun, wind, biofuels including algae, tides, rivers, and many technologies that have been buried by the fossil fuel industry. But if we changed direction and steered towards renewable energy, that would light a huge outbreak of new technologies and discoveries. Don't be a chump and believe the scam of the fossil fuel industry. They are into everything now, even the schools and colleges and they virtually pull the strings of the media.

    This is a real phenomena and it is very serious. As the glaciers melt into the ocean, they will disrupt the ocean currents. This is what causes severe weather, and is what is believed to have caused the last ice age. Currently, there is a piece of glacier cracking in Greenland and when it breaks off into the ocean, as it melts, it threatens to send the northeastern part of America into an ice age. So, for all of you out there who are so against global climate change, I suggest you do some research and get your facts straight. Also, when you find an article contradicting global climate change, look and see who funded it, because I can almost guarantee you it is an oil company.

    I'm a believer in global warming. So my question is what can I do as a person to make things better. I live on five acres and have been thinking of planting it in trees. I recycle. I drive a hybrid car. What are some other things that we can do as individuals, because I believe there are a lot of people like me out there that would like to make a difference for our children.

    February 24, 2013 at 4:57 pm |
    • DMW

      Wow Cam, I am always talking about climate change and I never hear someone ask this question. So I tip my hat to you. You are doing a lot more than others simply by using the hybrid. If the economy was based on a footprint "ration" that people bargained with you would get points for using that hybrid. Of course we have to change our economy – that is the big picture. It seems impossible but it's not. We can do amazing things if we all decided we were going to lick this thing. Since you live on a decent piece of land, you could grow organic food. Organic food is synergistic for the soil as well as for human consumption. Organic fertilizers keep the soil packed with mitochondria which nourish the plants and get all the bacteria flowing right keeping the soil in a condition that absorbs moisture for efficient uptake of nutrients for the plant. If you make enough you could sell herbs, vegetables and even flowers at the local farmer's market. Same with fruit trees. Just so you know (it's so wonderful to have someone who actually wants to do something about this! Believe me it's rare) we're not going to fix this mess without the help of the cannabis plant. Industrial hemp can replace cutting down trees, it can replace cotton (cotton uses 50% of the world's pesticides) and we can even make car bodies out of it like Henry Ford did: Hemp is an extraordinary plant its seeds are also one of the most nutritious foods on the planet. So every chance we get, we have to inform people about this plant and get it off the Controlled Substance list – it is criminal that it remains there. Houses made from hemp/crete are 75% more fuel efficient and are fireproof, rodent-proof and termite-proof. We have to get this growing everywhere. It also absorbs mercury, pesticides and heavy metals from the soil. So many things about it are excellent. It was wonderful to see your commitment. If only we all were like that.

      Im just like you cam:) im one of those small individual people that try to help the environment to make it a better place for ourselves and for our future generations. Its the little things: recycle, i make sure my water tap isnt dripping, turn off the lights i dont need, or all of them when im gone, and above all, i try to avoid using my car as much as possible. Like i said, its the little things that make a big difference:)

    Seems many memories are short or out grown, the 1938 hurricane was horrible and topped any of the recent ones. Even this last north East snow storm was not any worse than 1947,1978 and 1993 all of which matched or beat this recent one. The media pumps these events for sensationalism, do a search on the glaciers in the Himalayas they are growing. These changes are just natural events, our earth has and will go through many changes many will not be good for man kind.

      I suggest you stop listening to the media and put your head in a book and fill it with some facts. You may not have experienced anything worse but you are not the only one. Everywhere in the world climactic events are happening with more frequency and happening just the way the climate scientists predicted in the 1970's. We are on a collision course with our own extinction and people like you are taking us down because of your willful ignorance.

      I grew up in Alaska through the 70’s to the 2000’s. During that time alone glaciers that used to be literally a stone’s throw away have receded so far back that you have to not hop on a boat and take a 20 minute ride just to see what remains of the face (Portage Glacier). Others have gone entirely.

      Our winters have gotten warmer, our permafrost has begun to melt and the Arctic Ice has shrunk, forcing large polar bears to migrate south to land to feed for the first time in known history.

      Creeks where I used to live are long since gone. Lakes have shrunk. Herds have thinned.

      Don’t try to tell me nothing has changed just because you haven’t seen it when the rest of the world has – and I have personally. You know the saying – when you seem to have a problem with everybody, it’s usually your problem, not theirs.

    It doesn't matter what we do, since Brazil is going to keep chopping down the Amazon, and China, India and all the other 3rd world nations are going to continue to increase their CO2 emissions. As for all the deniers, just wait until the methane hydrates let loose from the Arctic. That is the wild card that will rapidly increase warming, and there are signs that it will happen a lot sooner than expected. I think when the East Coast is under 6 feet of water, they'll get the drift....well,at least the wet ones. Those deniers are a tough sell, kinda' like Ross Perot, but without the brains. As for the argument that climate change is natural, it is. However, what is not natural is the rate of CO2 increase in the 20th century and beyond. That is the driver for the current warming, and it's hard not to blame the deforestation, along with the burning of huge amounts of fossil fuels. Unlike a volcano, which can emit a huge amount of CO2, and dust (which has a cooling effect), in a short burst of time, we are constantly emitting kilotons of CO2 all day, every day, and removing the trees and swamps that remove the CO2 and generate oxygen. We're brilliantly shortsighted. Bummer for our kids.

    Our history of weather and temperature in the U.S. only goes back to the late 1800s. We shouldn't trust the words of our politicians. Scientists are darn well unreliable, omitting the information that doesn't agree with the story they want to tell as well as simply making gross mistakes (remember that hockey stick temp forecast). If you want the truth look for examples of weather from the 1930s to the end of the 1990s. You'll see we get hot, we get cold, we get dry and we get wet.. Its the ultimate example of hubris when we think we have any significant effect on climate.

    February 23, 2013 at 9:53 pm |

      The Hockey Stick was not a 'temperature forcast' it was a reconstruction o fpast temperatures to the present day.
      There are now around 11 or 12 hockey sticks, each one has been constructed from different proxies and by different teams of scientists from different countries at different times.
      And guess what ?
      They all show exactly the same thing.
      There is NO 'debate' about human caused climate change among the scientific community and there hasn't been for decades. We know beyond any doubt that there is no 'natural cycle' that can explain the loss of 80% of Arctic ice volume in 25 years.
      There are vurtualy no climate scientists on Earth who are not in agreement about what the evidence shows.
      Human beings have been effecting the climate on Earth for thousands of years to a minor degree – these days we have increased the level of a pwoerfull greenhouse gas by 40% in around a century. OF COURSE this is affecting the climate. How can it possibly NOT effect the climate?
      The climate has ALWAYS changed.
      In the past every time CO2 levels have risen the climate has changed.
      The laws of physics don't give a damn where that CO2 comes from. It doesn't matter if it is from the hundreds of billions of tons of CO2 outgassing from some prehistoric ocean or from the hundreds of billions of tons of CO2 being pumped out by humans burning carbon.
      The laws of physics dont care at all – they just do their thing.
      CO2 rises = global temperature rises.
      Every single time.
      Always has – always will.
      How can it not?

        But you are not telling people here the ACTUAL TRUTH. There are slews and slews of extremely reputable scientists who have not jumped on the bandwagon of the line that "climate change is primarily due to human activity." Do a little further research and you will come to articles that will shake your faith in the fable that "there is no question" about the total role of human activity in this phenomenon. In point of fact, many phenomena do not conform to the picture you are trying to ram down the throats of people if there were NO other sensible theories. Your readers should ALSO know that there is HUGE, HUGE money for Companies who have embraced your line and have proposed hugely expensive projects to "store or bury carbon." In addition, there are reputable Universities who have not looked kindly on certain faculty members WHO DO NOT SHOW THE KNEE JERK mantra of human activity being the ONLY story to be told. In fact, some of these Universities have even dismissed certain faculty members who were not the "true believers" from receiving TENURE!! How is that for your "rational view" of the "science" behind the global warming game????????
        Other scientists have proposed that much of what has been attributed to human activity may be more easily explained by variations in solar activity and you can find papers on this quite easily. I am not talking about "quacks" but researchers in the field of climate change who have been published in the most notable relevant journals. The story is an unfolding one, it is not written in stone...and there are still a great number of people in science who have the wisdom to see the holes that remain in the current "closed case on Climate Change" that you have swallowed. What you suggest is FAITH....and the Party Line...but wiser minds, and plenty of them, are shaking their heads and NOT AT ALL CERTAIN. And they have no other agenda but to look at the OVERALL data.

      • ChuckW

        You are missing a serious point here. The vast majority of scientists who have spent years studying climate and weather have concluded that man is greatly contributing to climate change and the overall temperature of the earth's surface is warming at a much faster rate than can be explained by any other phenomena that is currently taking place. Let's assume, for a moment, they are all wrong. If that's the case, then reducing carbon emissions would have little effect globally, but would greatly improve local situations (less smog, pollution, etc.) Strikes me as an overall plus. If, on the other hand, their research proves to be true, doing nothing to change what we are doing now will rapidly lead to a tipping point that will cause massive dislocations to civilization in the next couple of centuries. We have been ignoring the alarms for years. So the real question here is; should we do nothing and take a significant risk that there will be massive dislocation for our children and grandchildren, or should we do something and possibly mitigate against that, but certainly leave them a planet as clean (or better, cleaner) than the one we inherited? I always learned it is cheaper and easier to clean up your mess as you make it, rather than wait until you are done and then try to clean up the large mess you leave behind.

        I would love to think scientists are wrong, but I am not willing to bet the future of mankind on it.

      Hurricane Sandy was the second most powerfull storm in US history,
      It was second only to Hurricane Isobell in 2003.
      Scientists measure Hurricanes on the IKE scale. The 'Catorgory' system referes only to the sustained wind speed at the storms core. Sandy was only a 'Cat 1' when it made landfall but on the IKE scale (Intergrated Kinetic Energy) that measured ALL of the storm from the core to the edge some 500 miles accross it wighed in at an incredible 140 terajoules – that's about 20 terajoules more than Katrina which as a 'Cat 5'.
      It's probably not a good idea to post about hurricane strength on a public forum when you have no idea what you are talking about.
      Same goes for all the "The climate's changed before'"arm-chair 'experts' – most of whom clearly don't even understand basic schoolboy physics let alone climate systems.
      The climate has always changed – Well DUH!
      Yes. In the past the climate has changed every time CO2 levels have risen.
      Every time.
      Perhaps some of these 'experts' woul dlike to show their scientific evidence as to why the climate won't change THIS time?

      Capster, your comment is beyond words, either you were drunk off your ass the entire lengh of the storm, or you were visiting another country:/ i watched every moment of that Hurricane destroy the coast for over 2 hours with devastating effectivness. "hurricane Sandy was not even that bad of a hurricane"..what are you high?? no, your just stupid.

    What is more extreme today about extreme weather than our Great Grandparents and Granparent experienced in the drought stricken dustbowl days of the 30s. For every extreme weather event we've had in the last 10 years, you can do a quick internet search and find an even more extreme event in 30 years ago, or 60 years ago , or 100, or 150 years ago before Global Warming...oops Climate Change was even a thought. The greatest death tolls from drought, famine, hurricanes, floods, and even tornadoes hasn't happened in the last 10 or 15 years, but much futher back in history. Extreme weather? Superstorm Sandy? Sandy came ashore as a cat 1 hurricane, not some killer cat 4 or 5. And it wasn't the hurricane that cause so much flooding it was the fact that the storm surge as it came ashore happened during a full moon and high tide. Bad timing, not extreme climate made Sandy so damaging. And of course the fact that many more people than in all of history have built their homes right on the beach.

      The ecosystem is similar to a terrarium. It's like a closed loop. The decayed matter is trapped deep into the earth having little effect on the current system. It takes millenia to form fossil fuel. It is formed by decayed matter over and over many atmospheres. While it was forming, the earth had a balance – plants take in CO2 and sent out oxygen which provided animals with oxygen and they breathed out CO2. It's a complex system but basically Nature provides a balance. Now industrialization comes along and digs up that extra carbon, burns it into the atmosphere so it injects tons upon tons of CO2 per day and they cut down the "lungs of the earth" the trees. The oceans absorb much of the carbon. It makes the oceans warm. The ice at the poles melt. The reduced white surface of the ice sheets causes more heat to be absorbed by the oceans due to the darker surface area. The ice melts ever faster. And this is the loop we now are in. We have damaged the balanced loop of Nature and have created a new loop. Now with the economy you can see that if you spend more than you earn, you're going to have a problem. But somehow that logic doesn't follow in matters that are based on self-interest. We can have free energy but the fossil fuel companies spend billions to keep us stupid. And it works. If you think you need to be a scientist before you can see that we're destroying our own life source, then you're dumber than dirt.

    Nobody has ever argued that the climate doesn't change on its own. What is being argued is that it normally takes tens of thousands, if not, hundreds of thousands of years, not 100 or 200 years. That time differential has a HUGE impact on the ability of living things to adapt–evolve–to their environment. What nobody knows is what that impact will be: severe storms; microbial infestations; sea level rises; will the oxygen content change? It is a truly undefined matrix.

    • Eve Stevens

      You may want to look up the Younger Dryass period in which tmeperatures went up and back down 10 C in less than a decade. That was climate change, entirely natural. You all want to do something or have your government do something. The only thing you can do is to shut off your electricity or wait until your government does it for you.

      • hypostasis

        That is called a spike, not a change.

        February 24, 2013 at 9:26 pm |
      • hypostasis

        Also, it's Younger Dryas, one 's', and it occurred during the Holocene period, 400,000 years ago, and one of the major causes that has been argued is major volcanic eruption. Just like how Mount Pinatubo dropped the earth's temperature for a few years.

        February 24, 2013 at 9:51 pm |
      • Eve Stevens

        Then you can't read because the Younger Dryas occured at the end of the last galaciation, not in the Holocene. It was not one spike but repeated up and down's that lasted for 1300 years. So far, I have learned that you can't read, have no knowledge of climate history, but you believe your use of fossil fuels is destroying the planet yet you continue to drive and use electricity. Go ahead, keep screaming about climate change when we are living in the most stable part of the Holocene. Ask your government to do something and they will. They will make energy so expensive that you will die of cold. at some point you will stop posting.

        We're dealing with bullies. The fossil fuel industry ripped out all the once prolific railroads. Then they made sure there was no other alternatives. By being on oil we are connected at the hip to the fossil fuel, the substance that is poisoning the world we live in. But the fossil fuel industry has to be made to step back, they are not going to go down willingly. Because go down is what they will have to do. We had to learn how to retool, now it's their turn.

        February 24, 2013 at 11:54 pm |
      • hypostasis

        Firstly, Eve, I never stated or implied anything about the usage of fossil fuels; that is from your lack of reading and wishful projecting. Secondly, I will admit to a typographic error of 400,000 instead of 40,000 years. As for the rest, a spike is still a spike, even if it’s repeated 1000 times. And something else we’re going to disagree on: We are currently living in the Anthropogene epoch. Also, you should learn how to spell: occured is occurred and galaciation is glaciation. When your spelling is that atrocious it diminishes any point you try to make. Furthermore, sentences begin with a capital letter: "At some point you’ll stop posting."

        February 26, 2013 at 3:21 am |
      • hypostasis

        Eve, I will use smaller words and less complex sentences so you can understand what I am saying. If you had read my first post and understood it: “Nobody has ever argued that the climate doesn't change on its own. What is being argued is that it normally takes tens of thousands, if not, hundreds of thousands of years, not 100 or 200 years. That time differential has a HUGE impact on the ability of living things to adapt–evolve–to their environment,” you would have known that the Younger Dryas was not only the exception that proved the rule–it normally takes tens of thousands, if not, hundreds of thousands of years for the climate to change–but also a sterling example of the impact of a sudden change in climate: It took one asteroid, which became a meteorite when it impacted the earth, to wipe out the dinosaurs; and from Richard Firestone’s peer reviewed paper: The Case for the Younger Dryas Extraterrestrial Impact Event: Mammoth, Megafauna and Clovis, “Approximately 12.9 ka ago the Northern Hemisphere suddenly experienced a return to glacial conditions lasting >1000 years called the Younger Dryas (YD) that reversed the warming of the preceding interstadial deglaciation… At the same time mammoths, many other megafauna, smaller mammals, and birds suddenly became extinct in North America. At least 35 mammal genera disappeared (Grayson and Meltzer, 2003) and all evidence of Clovis culture in North America abruptly ended (Waters and Stafford, 2007). C. Vance Haynes (2008) has identified a black, organic-rich layer or “black mat” at 70 Clovis-age sites that started forming 12.9 ka ago (Taylor et al. 1996). As Haynes described it, the "mat covers the Clovis-age landscape on which the last remnants of the terminal Pleistocene megafauna are recorded." No skeletal remains of horse, camel, mammoth, mastodon, dire wolf, American lion, short-faced bear, sloth, tapir, etc., or Clovis artifacts have ever been found in situ within or stratigraphically above the YD-age black mat. Haynes (2006) concluded that the "extinction of the Rancholabrean megafauna was geologically instantaneous, essentially catastrophic." This is inconsistent with other theories proposed to explain their disappearance including human overkill (Mosimann and Martin, 1975). Human predation fails to explain either the absence of kill sites for 33 extinct mammals or the rapidity with which they disappeared. Abrupt Younger Dryas cooling has also been implicated in the demise of these megafauna and mammals (Guthrie,2006). However, similar episodes have often occurred during the past 80 ka, and none were associated with major extinctions. Additionally, no evidence exists for suspected pandemic disease (MacPhee and Marx, 1997) in the Pleistocene record, and the elimination of so many varied species by disease seems unlikely. Simultaneous sudden extinctions and rapid onset of Younger Dryas cooling, followed by the appearance of the black mat, clearly indicate that a catastrophic event such as major volcanism or an extraterrestrial impact event occurred 12.9 ka ago. However, analysis of sulfate in Greenland ice (Zielinski et al. 1996) indicates that there was no major North American volcanic episode sufficient to have caused a catastrophe of this magnitude at that time. Consistent with an extraterrestrial impact event, Firestone et al. (2007) reported the discovery of a thin sediment layer at the base of the black mat at 10 Clovis-age sites across North America and a site in Belgium containing numerous markers indicative of impact. Extensive stratigraphic and chemical analysis of sediments from these sites shows that this impact was capable of causing the Laurentide Ice Sheet to fail and the catastrophic conditions leading to the megafaunal extinctions. The black mat then would have formed from the ashes of the impact and the decay of plant and animal debris.”

        Do you understand now? Sudden change…sudden death.

      Do you apply that same logic to the fossil fuel companies? They spend billions to confuse the public over the facts on this issue. Why do you suppose that is? I've been an environmentalist since the 1970's and the prognosis has always been the same. With better technology over the years it has become more accurate. But way back then we were told there would be droughts and floods with greater frequency occurring. Have you not noticed that the deniers are not saying that the warming is due to sun flares anymore? Of course these proponents never projected what sun flares would do to the climate. Unlike the people warning of climate catastrophe who have predicted with high accuracy more than thirty years ago. This scientist is a nice guy and all but too wimpy to give an accurate illustration. Already the permafrost is exploding into the atmosphere in the Arctic. I always thought that's bye bye planet but if we move quickly, we may have a small window where we can grow industrial hemp for paper, clothing, biofuels, bioplastics etc instead of cut down trees and dig up carbon to burn into our own atmosphere. What idiots humans are!

    The climate has been hotter and cooler than it is right now. How did that happen without man-made green house gases? Factors other than man-made green house gases caused that change. This is not disputable. Proving the climate is changing does not prove that man caused that change. Correlation does not prove causality and the correlation is weak and even negative at times.

I would not say we might not speed it up some, but I do not think we will be doing anything that the planet does not do to itself anyway. We are simply entering the next Ice age, plain and simple and we will need to deal with it or die out as countless spiecies have before us. However to assume that 100,000 years of tree rings is enough data on the worlds climate to issue a statement of certainty is mistaken. Good solid evidence years, do not get me wrong or think that i am attempting to downplay it, but i would not use it as a complete justification by any means either.

Miniscule changes over a long period of time will eventually make a difference and it isn't wise to wait till the last second to do something about it.

Wake up MORON before your family is killed in a weather related event. The good news is that most global warming skeptics are in the states that will be the most affected from Texas to Florida.

    You are welcome to deny climate change all you want. It is not just about rising sea levels or longer summers or less snow. It is about places on earth that are now used to grow the food we depend on becoming deserts and the wetlands that used to protect us from catastrophic flooding dying off or being drowned. Climate change is real. Can anyone say with 100% certainty how much of it is man caused? No, of course not. What most realistic scientists have been saying for some time now is that the evidence shows mankind has had quite an effect on the climate, and the activities of man are, at best, speeding up climate change. When the oceans were higher, thousands of years ago, mankinind was nomadic and could move easily rto where the food was. Today, we cover much of the inhabitable zones of the planet, and the ultimate result of climate change will be major famine, not just in the places where famine always seems to exist, but throughout the developed world, too. If you wish to be blind to the evidence, or say it hasn't been proven, what you are truly saying is "I really don't care about man in the future, as long as things remain OK in my lifetime." If you did, you would do what you could to help the situation and back a global attempt to mitigate future damage. Climate change is not some liberal plot to destroy civilization. This is a conservative plot to protect it for as long as is possible.

    Yes, use the terms extreme weather and climate change. It is not simply global warming. The book "The Coming Global Superstorm" by Bell and Strieber is a good description of this.

    Ask any geologist about global climate change- it's huge and the record is written in the rocks. The problem for human beings is not climate change, that is unavoidable. The problem is the rate of climate change, do we have centuries or years to adapt? When the climate changes fast the costs to human civilization are high. It is undeniable that the golbe has been erratically warming for the last 12,000 years and that we in a period of more rapid warming. Wheteher we are causing much or all of this rapid warming probably won't be scientifically proven in our lifetimes, but if we are, we will have made a Big Mistake. We need to hedge our bets and start reducing CO2 emissions. A CO2 tax lets the market figure out the best way, we could even make it revenue neutral by offsetting reductions in other taxes.

        Well sort of true about last ten years: If you look at the last few years in the larger context in this chart it could be a short term levelling off before more rising as has been seen in the past at times. But given that it hasn't made a notable drop it's reasonable that the curve will continue as it has rising, leveling or slightly falling then rising again.

    The "fact" of Global Warming is based on trend estimation – predicting future temperatures based on past data. Building simulation models around trend estimation is what scientists do when they don't understand what's going on.
    Let me say it delicately: only a fool would call "incontrovertible evidence" results based on empirical curbe fitting.

    February 22, 2013 at 5:11 pm |
    • alan

      No, the fact of Global Warming is based on the study of PAST climate data. The concern that scientists feel is based on extrapolation. If they are right, and the vast majority of evidence says they are, we are in trouble. The world won't end, but there will be significant disruption to what we believe is the normal situation: weather, food production, disease, etc. will all be different. Even the US military sees this as a threat.

        I think this is true. But it will be a good thing for the population to go down, as more people will die in these extreme weather evenst and droughts where there is not enough food. The planet is just righting itself.

      I think most of us who have read on this subject and have considered the evidence as presented to us by folks such as the highly reputable scientist interviewed for this article, know who the fools are.

      Be careful what you write in these comment sections. Future historians will be mining this data when they search for the small-minded, self-centered people who refused to do anything about global climate change even when the evidence they confronted was quite clear.

    Simple solution – move away from the coast. Buy land in Houston – one day it might be beach front property. Point being, significant climate change (if true) won't cause the world to end. We'll adapt and overcome as we always have. A few people might die, but that's the risk of life. I for one am looking forward to my extended summer vacations. 🙂

    Believers, Deniers, Former Believers,
    What sick satisfaction do we get by wanting to believe in a cataclysmic climate crisis for our own children? If we were living in a real civilized society we would have legal consequences for issuing these CO2 death threats to billions of helpless children.
    But this fear mongering we do feels like the right thing to do doesn't it because it’s about “our planet and “our children" and what is wrong with loving the planet and being concerned about it? Right? You would have to hate the planet to not believe in climate change? I just feels good to do the right thing?Why would science lie we ask ourselves; they say it's real and who is going to argue with what the world of science says and if a headline says so; it must be true? Yes our planet is doomed to a climate crisis because of Human CO2 because we must be doing something to our planet. Just look at the crap we throw at poor Mother Nature Does that feel good.
    To jump at the chance to condemn our own children to the greenhouse gas ovens is not what good loving and honest people do. REAL planet lovers don’t want this misery to be real and real planet lovers love the planet with love, not fear. Science gave us pesticides and science only agrees; “it is real and happening” but only “could” be a crisis. NEVER has the world of science said any crisis was imminent. Never.
    If you still believe in the CO2 mistake and tragic exaggeration, just remember that history will catch up with you and label those responsible this needless CO2 panic as “end of the world freaks” in another circus of Reefer Madness.

    • StevenR

      No. Global Warming is a fact. Is is happening. Theory (models) and observations confirm is it happening. It will be a crisis – it really already is if you are living is a drought or flood (or both) plagued area. You denials are an indication of extreme ignorance.

      I suggest you test another THEORY of science – the THEORY of gravity. It is as untested and questionable as the THEORY of GLOBAL WARMING. Go ahead. Jump off a tall building. Gravity is only a theory. Go ahead, jump.

      You won't be missed.

      • mixed_signal

        What do you mean 27 years of wrong IPCC predictions. The central predictions have been and continue to be increased average temperature, more heat leading to more moisture in the atmosphere leading to more water and energy in storms, including more snow (overall more precipitation and more violent storms), and more variation in weather patterns. The temperature predictions have always had large, clearly spelled out error bands and probabilities. There's nothing inconsistent with these IPCC statements and summaries. Can you point out specifically what is?

    I'll be long gone to the great beyond when the worst of this is here. Nevertheless, right noticed a tremendous change in planting times, plant behavior and weather in the last 40 years. Is it due to man or just a natural cycle. I don't know, but I don't much like it. Just a fact to think about. Do you thing 7 billion human beings, or 7 billion of any other species, has an effect on their environment or not? I think 7 billion anything is going to have an effect, I just don't know if it is good, bad or just another natural cycle.

      The Earth will survive us. We know that at many points in Earth's history co2 levels have been much higher and the level of biodiversity much greater. If we're all worried about having our coastal cities inundated with rising sea levels then that isn't new. Cities that were once on the coast are now miles inland and those that were miles inland are now on the coast. Just look at Hissarlik, or Troy. The toll mankind takes on the ecosystem, in terms of biodiversity, or ocean acidification will be what really has a lasting effect. Up here in Canada we have seen a temperature increase of almost 1 degree, this was due to the massive tree die off in B.C caused by the Pine beetle, not co2 levels, but this doesn't make the threat any less dire.

        Because we no longer cut down the dead and dying trees. Native Indians used to burn back the forests and so did we until big government decided it was better not to. Now we have a lot of dying trees, pine beetles and dead trees. Perfect for a great forest fire.

    *Canada killed Y2Kyoto with a freely elected climate change denying prime minister and nobody cared, especially the millions of scientists warning us of unstoppable warming (a comet hit).
    *Until now Obama had not mentioned the crisis in the last two previous State of the Unions addresses.
    26 years of the all the scientists only saying it “could” be a crisis, never saying it “will” be a crisis means it won’t be a crisis, because “maybe” isn’t a lie. Help my house could be at the point of no return possibly from being on fire maybe? This Reefer Madness of climate blame is our legacy and real planet lovers are glad a crisis was an exaggeration.

    If this really is a climate "crisis" then find us one single IPCC warning that says it "will" happen not just might and could and likely happen and if it were really a "crisis" they would say so and not qualify every warning with a "maybe". Help my house could be on fire maybe? How close to unstoppable warming will the lab coats take us before they say a crisis is "imminent"? Comet hits are "imminent" but climate change crisis isn't?
    27 years of research only saying it might happen proves it won’t happen. Deny that!

      All science except pure mathematical proofs involves statistical probabilities over the outcome. IF a building inspector told you it was "very likely", a 95% probability, that your house's poor wiring will cause it to catch fire, would you then say "Oh, it's not going to happen because he didn't say it was imminent"? Why are you unable to wrap your head around this fact?

    The comments about the oceans rising is true – they have been rising since the last ice age. The oceans rise and fall by 600-700 feet between ice ages. As the ice age forms the ocean waters are converted to snow and ice lowering the ocean levels, as the ice melts the oceans rise.
    The fact that oceans are rising is expected. Is the oceans rising faster than normal I don't know if anyone knows. We do know that the Pacific Island going under water shows that the ocean was 60-70 feet lower 3,000 years ago because the caves where people lived are 70-80 feet below the present water line.

      ...and the rate of increase is increasing. We should be going into another ICE AGE and the temperature is CLIMBING. That ain't right. WE ARE KILLING OURSELVES. The scientists mention on the likely scenarios. You want one that is UNLUIKELY but TOTALLY POSSIBLE? You want the WORST TAKE on what CAN HAPPEN?

      How about the phytoplankton in the ocean die off and the oxygen concentration drops by about 40%. ALL HUMAN LIFE ON EARTH ENDS.

      Now that is not LIKELY but it is POSSIBLE. No REAL CONSERVATIVE would let even the SLIGHTEST POSSIBILITY of that happening exist. ALL MEASURES would be used to make it IMPOSSIBLE.

      But an IGNORANT REACTIONARY like a member of the GOP would probably let that SLIDE to make an extra BUCK.
