97% of climatologists believe in man-made global warming

[dilloduck]

jreeves, there is no theory involved, only fact.

Atmospheric CO2 causes the earth to retain heat. We have increased atmospheric CO2 by 40% in the last 200 years. Therefore, we have caused the earth to warm.

None of the above statements is a theory.

who cares and why ?

“I am a skeptic…Global warming has become a new religion.” - Nobel Prize Winner for Physics, Ivar Giaever.

“Since I am no longer affiliated with any organization nor receiving any funding, I can speak quite frankly….As a scientist I remain skeptical. “The main basis of the claim that man’s release of greenhouse gases is the cause of the warming is based almost entirely upon climate models. We all know the frailty of models concerning the air-surface system” - Atmospheric Scientist Dr. Joanne Simpson, the first woman in the world to receive a PhD in meteorology, and formerly of NASA, who has authored more than 190 studies and has been called “among the most preeminent scientists of the last 100 years.”

Warming fears are the “worst scientific scandal in the history…When people come to know what the truth is, they will feel deceived by science and scientists.” - UN IPCC Japanese Scientist Dr. Kiminori Itoh, an award-winning PhD environmental physical chemist
“The IPCC has actually become a closed circuit; it doesn’t listen to others. It doesn’t have open minds… I am really amazed that the Nobel Peace Prize has been given on scientifically incorrect conclusions by people who are not geologists,” - Indian geologist Dr. Arun D. Ahluwalia at Punjab University and a board member of the UN-supported International Year of the Planet

You bush supporters keep clinging to this "list of 600 scientists". Its been debunked over and over. And why are you linking to a rightwing Senator's website anyway, instead of to a nationally recognized scientific organization with expertise in climate science?

Some of the people on Senator Inhofe's list have asked to be taken off. Some are quoted out of context.

And many simply aren't experts in the field of climate science. Why is this the one area in your life, where you would value the opinion of non-experts, rather than the research and conclusion of actual experts in the subject area?

Do you go to a dentist when you have a respiratory infection? No, you don't. You go to an internal medical specialist.


I looked up the first three guys on your list.

The first guy did research decades ago on super conductors and electrical physics. . Not a shred of expertise in modern climate science.

The second guy is an industrial chemist who's never done research in climate science and doesn't have a single peer reviewed published paper in climatology.

Dr. Kiminori Itoh declares himself as a "physical chemist familiar with evironmental sciences, and not particularly specialized in climate science." According to Google Scholar and Yokohama National University, Dr. Itoh has not published any work in the area of climate change in peer-reviewed science journals

The third guy is a geologist. I might ask him about rocks. But, I would never seek out his "opinion" on climate science.

I suspect the basic picture of results are correct but I hate it when media put out a description of a survey without providing some access to details about the methods. The minimal description provided suggests that it was not a "scientific" survey and I wish there was an easy way to find out if that impression is correct or not. I did a Google search to try to find more details, including going to a Science News article then going to a website for the publication it was in and no luck.

Otherwise, I'm among people who believe there's been a warming trend and that human activity has been a factor. What I don't believe is that unvalidated models can allow us to say that if we do or don't do X then Y or Z will happen within reasonable bounds of certainty that are of practical value. I also don't believe we know it's going to be some massive disaster for the planet if the Earth, which has been both much warmer and much colder than it is now or than it's predicted by the unvalidated models to be 100 years from now during the tenure of life on it, if we don't take draconian action.

And I'm of the opinion that there is a pervasive bias in the scientific community as well as western civilization at large towards being inclined to believe that anything different about the planet that is the result of human activity is "bad." There seems to be this preservationist mentality holding that the imagined state of the planet as it would be without humankind at this instant...with the certain set of species in place and all...is the best it's ever been or will be and that some different set of species and/or conditions is catastrophe.

The planet has been in a constant state of change since it started. There is no fixed, "balanced" ecosystem. Things have changed more slowly at times. Things have changed more quickly at times. I just don't agree with the hysteria over it.

I've been asking all weekend for a link from denialists and flat earthers, to a recognized and established national or international scientific organization with expertise in climate science which supports their denialist position.

I give up. All I've been linked to is

-A rightwing website called "heartland.org"

-A list of "600 scientists" from a rightwing senators website. Who's going to trust a list in which some scientists have asked to be taken off, and most of the scientists aren't experts in climate science, don't have backgrounds in it, or even do there own researh on the topic?

-Some guy named "Dr. Bob Carter" from some place called "James Cook University"

-An "Institute", which is nothing more than a crack pot think tank located on a farm in Oregon, and promotes homeschooling and how to survive nuclear war.

-A wikipedia link to a list of "skeptics" in the science community, even though the wiki page itself explicitly states that the scientists on the list don't neccessarily deny that humans are affecting climate or that it will be harmful. They're most just debating around the edges about quantification parameters and methodology.


Look, when you wait for 48 hours to get a credible link to an expert organization which is highly qualified in the field, and rightwingers are still unable to provide one, then the debate is over. They've got nothing. They're shooting blanks. They just have a partisan belief system about it that isn't backed up by anything substantial or expert.

I Was On the Global Warming Gravy Train - David Evans - Mises Institute

I devoted six years to carbon accounting, building models for the Australian government to estimate carbon emissions from land use change and forestry. When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty conclusive, but since then new evidence has weakened that case. I am now skeptical.

In the late 1990s, this was the evidence suggesting that carbon emissions caused global warming:

1. Carbon dioxide is a greenhouse gas, proved in a laboratory a century ago.

2. Global warming has been occurring for a century and concentrations of atmospheric carbon have been rising for a century. Correlation is not causation, but in a rough sense it looked like a fit.

3. Ice core data, starting with the first cores from Vostok in 1985, allowed us to measure temperature and atmospheric carbon going back hundreds of thousands of years, through several dramatic global warming and cooling events. To the temporal resolution then available (data points more than a thousand years apart), atmospheric carbon and temperature moved in lockstep: they rose and fell together. Talk about a smoking gun!

4. There were no other credible causes of global warming.

This evidence was not conclusive, but why wait until we are absolutely certain when we apparently need to act now? So the idea that carbon emissions were causing global warming passed from the scientific community into the political realm. Research increased, bureaucracies were formed, international committees met, and eventually the Kyoto protocol was signed in 1997 to curb carbon emissions.
"Correlation is not causation, but in a rough sense it looked like a fit."

The political realm in turn fed money back into the scientific community. By the late 1990s, lots of jobs depended on the idea that carbon emissions caused global warming. Many of them were bureaucratic, but there were a lot of science jobs created too.

I was on that gravy train, making a high wage in a science job that would not have existed if we didn't believe carbon emissions caused global warming. And so were lots of people around me; there were international conferences full of such people. We had political support, the ear of government, big budgets. We felt fairly important and useful (I did anyway). It was great. We were working to save the planet!

But starting in about 2000, the last three of the four pieces of evidence above fell away. Using the same point numbers as above:

2. Better data shows that from 1940 to 1975 the earth cooled while atmospheric carbon increased. That 35 year non-correlation might eventually be explained by global dimming, only discovered in about 2003.
3. The temporal resolution of the ice core data improved. By 2004 we knew that in past warming events, the temperature increases generally started about 800 years before the rises in atmospheric carbon. Causality does not run in the direction I had assumed in 1999 — it runs the opposite way!

It took several hundred years of warming for the oceans to give off more of their carbon. This proves that there is a cause of global warming other than atmospheric carbon. And while it is possible that rising atmospheric carbon in these past warmings then went on to cause more warming ("amplification" of the initial warming), the ice core data neither proves nor disproves this hypothesis.

4. There is now a credible alternative suspect. In October 2006 Henrik Svensmark showed experimentally that cosmic rays cause cloud formation. Clouds have a net cooling effect, but for the last three decades there have been fewer clouds than normal because the sun's magnetic field, which shields us from cosmic rays, has been stronger than usual. So the earth heated up. It's too early to judge what fraction of global warming is caused by cosmic rays.

There is now no observational evidence that global warming is caused by carbon emissions. You would think that in over 20 years of intense investigation we would have found something. For example, greenhouse warming due to carbon emissions should warm the upper atmosphere faster than the lower atmosphere — but until 2006 the data showed the opposite, and thus that the greenhouse effect was not occurring! In 2006 better data allowed that the effect might be occurring, except in the tropics.

The only current "evidence" for blaming carbon emissions are scientific models (and the fact that there are few contradictory observations). Historically, science has not progressed by calculations and models, but by repeatable observations. Some theories held by science authorities have turned out to be spectacularly wrong: heavier-than-air flight is impossible, the sun orbits the earth, etc. For excellent reasons, we have much more confidence in observations by several independent parties than in models produced by a small set of related parties!

Let's return to the interaction between science and politics. By 2000 the political system had responded to the strong scientific case that carbon emissions caused global warming by creating thousands of bureaucratic and science jobs aimed at more research and at curbing carbon emissions.
"Science has not progressed by calculations and models, but by repeatable observations."

But after 2000 the case against carbon emissions gradually got weaker. Future evidence might strengthen or further weaken it. At what stage of the weakening should the science community alert the political system that carbon emissions might not be the main cause of global warming?

None of the new evidence actually says that carbon emissions are definitely not the cause of global warming, there are lots of good science jobs potentially at stake, and if the scientific message wavers then it might be difficult to later recapture the attention of the political system. What has happened is that most research efforts since 1990 have assumed that carbon emissions were the cause, and the alternatives get much less research or political attention.

Unfortunately politics and science have become even more entangled. Climate change has become a partisan political issue, so positions become more entrenched. Politicians and the public prefer simple and less-nuanced messages. At the moment the political climate strongly blames carbon emissions, to the point of silencing critics.

The integrity of the scientific community will win out in the end, following the evidence wherever it leads. But in the meantime, the effect of the political climate is that most people are overestimating the evidence that carbon emissions are the main cause of global warming.

I recently bet $6,000 that the rate of global warming would slow in the next two decades. Carbon emissions might be the dominant cause of global warming, but I reckon that probability to be 20% rather than the 90% the IPCC estimates.

I worry that politics could seriously distort the science. Suppose that carbon taxes are widely enacted, but that the rate of global warming increase starts to decline by 2015.

Imagine the following scenario. Carbon emissions cause some warming, maybe 0.05C/decade. But the current warming rate of 0.20C/decade is mainly due to some natural cause, which in 15 years has run its course and reverses. So by 2025 global temperatures start dropping. In the meantime, on the basis of models from a small group of climate scientists but with no observational evidence (because the small warming due to carbon emissions is masked by the larger natural warming), the world has dutifully paid an enormous cost to curb carbon emissions.

Politicians, expressing the anger and apparent futility of all the unnecessary poverty and effort, lead the lynching of the high priests with their opaque models. Ironically, because carbon emissions are raising the temperature baseline around which natural variability occurs, carbon emissions might need curbing after all. Maybe. The current situation is characterized by a lack of observational evidence, so no one knows yet.

Some people take strong rhetorical positions on global warming. But the cause of global warming is not just another political issue, subject to endless debate and distortions. The cause of global warming is an issue that falls into the realm of science, because it is falsifiable. No amount of human posturing will affect what the cause is. It just physically is there, and after sufficient research and time we will know what it is.

Unleashed: The ETS: Completely unnecessary

Rudd has failed to see through the vested interests that promote anthropogenic global warming (AGW), the theory that human emissions of carbon cause global warming. Though masquerading as "science based", the promoters of AGW have a medieval outlook and are in fact anti-science. Meanwhile carbon is innocent, and the political class is plunging ahead with making us poorer because they do not understand what science really is or what the real science is.

The Renaissance began when the absolute authority of the church and ancient texts was overthrown. Science then evolved as our most reliable method for acquiring knowledge, free of superstition and political authority. Suppose you wanted to know whether big cannonballs or small cannonballs fell faster. In medieval times you argued theoretically with what could be gleaned from the Bible, the works of Aristotle, or maybe a Papal announcement. In the Renaissance you ignored the authorities and simply dropped cannon balls from a tower and observed what happened - this was science, where empirical evidence trumps theory.

From 1975 to 2001 the global temperature trended up. How do you empirically determine the cause of this global warming? It turns out we can learn a lot simply by observing where the warming occurred: each possible cause of global warming heats the atmosphere differently, heating some parts before others. The pattern of warming is the cause's "signature".

The signature of an increased greenhouse effect consists of two features: a hotspot about 10 km up in the atmosphere over the tropics, and a combination of broad stratospheric cooling and broad tropospheric warming. The signature of ozone depletion consists just of the second feature. These signatures are theoretically derived by the Intergovernmental Panel on Climate Change (IPCC), and are integral to our understanding of how the atmosphere works. [1]

We have been observing temperatures in the atmosphere for decades using radiosondes - weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. The radiosonde measurements for 1979-1999 show broad stratospheric cooling and broad tropospheric warming, but they show no tropical hotspot. Not even a small one. [2]

Empirically, we therefore know that an increased greenhouse effect was not a significant cause of the recent global warming. (Either that or the signatures from the IPCC are wrong, so its climate models and predictions are rubbish anyway.)

Human carbon emissions were occurring at the time but the greenhouse effect did not increase. Therefore human carbon emissions did not increase the greenhouse effect, and did not cause global warming. So AGW is wrong, and carbon is innocent. Suspect exonerated - wrong signature.

Alarmist scientists (supporters of AGW) objected that the radiosonde thermometers were not accurate and maybe the hotspot was there but went undetected. But there were hundreds of radiosondes, so statistically this is unlikely. They have also suggested we ignore the radiosonde thermometers, and use the radiosonde wind measurements instead. When combined with a theory about wind shear they estimated the temperatures on their computers - and say that the results show that we cannot rule out the presence of a hotspot. But thermometers are designed to measure temperature, so it's a bit of a stretch to claim that wind gauges are accidentally better at it. Serious alarmist scientists do not claim that the hotspot was found, only that we might have missed it. The obvious conclusion is that the hotspot was too weak to be easily detected. We cannot collect any more data from the past warming, and there is no sign of the hotspot in the data that was collected - so the occasional claims that appear on the Internet that the hotspot has been found are simply wrong. [3]

So can we tell from the observed warming pattern what did cause the global warming? Unfortunately we have little idea of the signatures of some of the suspects, such as cosmic rays or the Pacific Decadal Oscillation, so we cannot say except to note that ozone depletion was one of the causes.

Is there any observational evidence in favor of AGW? As of 2003, none at all.

The only supporting evidence for AGW was the old ice core data. The old ice core data, gathered from 1985, showed that in the past half million years, through several global warmings and coolings, the earth's temperature and atmospheric carbon levels rose and fell in lockstep. AGW was coming into vogue in the 1980s, so it was widely assumed that it was the carbon changes causing the temperature changes.

By the late 1990s ice core techniques had improved. In the old ice cores the data points were a few thousand years apart, but in the new ice core data they were only a few hundred years apart. In the early 1990s, New Scientist magazine anticipated that the higher-resolution data would seal the case for AGW.

But the opposite occurred. By 2003 it had been established to everyone's satisfaction that temperature changes preceded corresponding carbon changes by an average of 800 years: so temperature changes caused carbon changes - a warmer ocean supports more carbon in the atmosphere, after delays due to mixing. [4] So the ice core data no longer supported AGW. The alarmists failed to effectively notify the public.

After several prominent public claims by skeptics in 2008 that there is no evidence left for AGW, alarmist scientists offered only two points.

First, laboratory tests prove that carbon dioxide is a greenhouse gas. But that observation tells us nothing about how much the global temperature changes if extra carbon enters the real, complicated atmosphere. Every emitted carbon atom raises the global temperature, but the missing hotspot shows that the effect is negligible.

Second, computer models. Computer models are just huge concatenations of calculations that, individually, could have been performed on a handheld calculator. They are theory, not evidence.

Governments have spent over $50 billion on climate research since 1990, and we have not found any actual evidence for AGW. [5]

So if there is no evidence to support AGW, and the missing hotspot shows that AGW is wrong, why does most of the world still believe in AGW?

Part of the answer is that science changed direction after a large constituency of vested interests had invested in AGW. The old ice core data provided support from 1985, the IPCC was established by the UN in 1988 to look into human changes to climate, and the Kyoto Protocol was negotiated in 1997 to limit carbon emissions. By 1999 the western political class were doing something, the western media were rallying behind "saving the planet", and scientists were being paid by governments to research the effects of human-caused global warming.

But then the evidence took science off in a different direction: the new ice core data in 2003, the missing hotspot in 2007, and the global temperature has stopped trending up since 2001 [6]. Governments, the media, and many scientists did not notice.

The remainder of the answer for the current belief in AGW is darker and more political. An offbeat theory in the 1970s, AGW was adopted by a group of about 45 atmospheric modelers and physicists. That group dominated climate science journals, peer reviewed each others papers, and hindered competing ideas by underhand methods [7]. AGW gained political support from proponents of nuclear power, and vice-president Gore appointed AGW supporters to science positions in the USA.

AGW grabbed control of climate funding in key western countries. Lack of diversity in science funding has been a major problem since government took over funding science in WWII. Science is like a courtroom - protagonists put forward their best cases, and out of the argument some truth emerges. But if only one side is funded and heard, then truth tends not to emerge. This happened in climate science, which is almost completely government funded and has been dominated by AGW for two decades. Skeptics are mainly scientists who are retired or who have moved on to other areas - their funding no longer depends on allegiance to AGW. The alarmists are full time, well funded, and hog the megaphone.

AGW was always promoted as being supported by nearly all scientists (though polls and history do not support this). Counting numbers of supporters and creating a bandwagon effect by announcing you are in the majority is a political tactic.

AGW always advanced principally by political means; as a scientific theory it was always weak, and now the evidence contradicts it. It's like a return to medieval times, where authority rules and evidence is ignored. Notice how the proponents of AGW don't want to talk about evidence of the causes? Anything but evidence of cause - attack people's motives, someone else "has the evidence", theoretical models, evidence that global warming is occurring, how important they are, what credentials they have, how worthy they are, the dog ate my evidence, "the science is settled", polar bears, anything. Talking about the evidence of the cause of global warming does not advance their cause. Politics says AGW is correct; science says it is wrong.

Science demands evidence. Evidence trumps theory, no matter what the political authority of those promoting the theory, even if they dress up in lab coats and have job titles that say "scientist". The hotspot is missing and there is no evidence for AGW. The alarmists cannot ignore this and continue to play political games forever. They are entitled to argue the case for AGW, but they should also acknowledge the evidence and inform the political class that AGW appears to be wrong - even if it means risking their status and their jobs (and yes, we scientists are also people who have kids and mortgages).

There are two central lies in the political promotion of AGW.

The first appears in Gore's movie. He gave the old ice core data as the sole reason for believing AGW (the rest of the movie presents evidence that global warming occurred, a separate issue). He said that increases in carbon caused increases in temperature in the past warming events. But Gore made his movie in 2005, two years after the new ice core data had established the opposite! Gore's weasel words when he introduced that segment show he knew what he was about to say was false. Who would have believed his pitch if he added "and each temperature rise occurred 800 years before the corresponding rise in carbon that caused it"? [8]

The second lie is the hockey stick graph, which presented the last thousand years of global temperature as the flat handle of a hockey stick and the next hundred as the sharply rising blade [9]. The hockey stick graph was heavily promoted by the IPCC in 2001, and the IPCC even adopted it as its logo before it got discredited. It is significant because most non-scientist AGW supporters seem to believe some version of the hockey stick. When the IPCC "scientists" who produced the graph were asked to show their data for past temperatures, they refused (true scientists share data). But one of those scientists was a British academic and subject to the British Freedom of Information Act, and after two years of stonewalling all was revealed. It showed they had grossly skewed the data (even omitting inconvenient data to a folder labeled "Censored"), and that the computer program used to process the data had the hockey stick shape built into it - you could feed it stock market data instead of tree ring data and you would still get a hockey stick! In reality it was warmer in the Middle Ages than today, and there was a mini ice age around 1700 from which we have since been warming ever since. [10] Finally, the sharply rising blade of the hockey stick is contradicted so far by actual temperatures, which from 2001 to 2008 have been flat - something all of the climate models got wrong.

Among non-scientists, AGW appeals strongly to two groups. Those who support big government love the idea of carbon regulations - if you control carbon emissions then you control most human activity. And those who like to feel morally superior to the bulk of their fellow citizens by virtue of a belief (the "warm inner glow" and moral vanity of the politically correct) are firmly attached to AGW. These groups are politically adept, are planning to spend your money and tell you how to eat, travel and how to live, and they are strenuously avoiding the evidence.

The media has avoided presenting information that undermines AGW, until recently. Instead they promoted alarmism, and discredited skeptics as being in the pay of big oil - while giving a free pass to Gore, who made a movie based on an obvious lie then made millions selling carbon offsets. The media is very keen to present evidence that global warming is occurring, but have you noticed how quiet it is on evidence that carbon emissions caused it?

In 2007 almost no one in the west knew that the hotspot was missing, that there was no evidence for AGW, that temperatures had been flat for six years, that the hockey stick was a fraud, or that Al Gore lied when he gave the old ice core data as a reason for blaming carbon. But due to the Internet the public is gradually finding out anyway, which risks further discrediting many media outlets. Why buy a newspaper if it's not going to tell you the actual news?

And as the public become generally aware, what politician is going to risk being so ideologically stupid as to unnecessarily wreck the economy by slashing carbon emissions? Hmmm, Kevin Rudd?

But I'm sure this guy is not at all qualified to have an opinion either.

Science will win out but right now politics and government money are tainting the process.

they need to move then

Maybe they could stay with you?

And many simply aren't experts in the field of climate science. Why is this the one area in your life, where you would value the opinion of non-experts, rather than the research and conclusion of actual experts in the subject area?

I'm new here but as you come to know me you'll see that I do not automatically accept something as known truth because it's what a majority or even an overwhelming majority of experts in a particular field say. I believe there are certain principles that transcend any particular scientific discipline. In this case, for instance, people who are familiar with the general principles of modeling are qualified to make judgements about such things as whether or not climate models have been validated to an extent necessary to consider them to be reliable predictive tools. They don't have to be climate scientists to do it.

I'll give you an example of a principle that transcends disciplines: In order to estimate a mean of a population from a sample, you have to have a probability sample. When climate scientists estimate the mean global temperature from temperatures observed at different points, they are not using probability samples. Certainly, when they look at temperatures from the 1800s, they're not looking at probability samples. When they go back before thermometers were invented and look at proxy indicators, they're not looking at probability samples plus they don't have any way to validate the conceptual models they're using. Such things raise questions and issues, especially when dealing with a situation in which an error of 1 or 2 degrees C in the estimate of the mean temperature would be viewed as a big deal. Or ice core data. That certainly can't be viewed as a probability sample of CO2 levels in past planetary atmospheres. Such issues can't simply be dismissed through saying, "they're the climate experts," and one doesn't need to be a climatologist to look into them and make judgements about whether or not the conclusions of climate experts might be off.

Don't get me wrong. I personally believe there has been a warming trend for various reasons beyond temperatures measured at different points. I also believe that it was way hotter than it is now during most of the history of life on this planet. But I think it's a mistake to automatically dismiss criticisms of client science from people who aren't climate scientists.

I find this all amusing.

Global warming is not a theory.

Atmospheric CO2 causes the earth to retain heat. We have increased atmospheric CO2 by 40% in the last 200 years. Therefore, we have caused the earth to warm. Soon we will have doubled the level of CO2 in the atmosphere, so we will have warmed the earth even more. The only thing that is saving us right now is that the land ice on Antarctica has remained cool because our CFCs have created a hole in the ozone over the South Pole.

Well just think--places that have shitty climates now will have a lot to look foreward to, chicken little.

If you were sick, and 11 out of 12 doctors who were experts in the field of oncology told you you had cancer, what would you do?

Take immediate action to take care of your health?

Or tell the doctors, that there was one dissenting voice and you should wait and do more research?


We all know which option you would choose.

No one ever said to always blindly believe the overwhelming majority of experts.

I don't know how old you are or what your life experiences are. But life is about risk management. Public policy is also about risk management.

You take actions based on the best expert advice. If the vast majority of doctors told you that tests indicated you had cancer, you wouldn't wait a single second to take steps to mitigate that risk. Life is always about making choices based on the best available information, and the level of action you take is always comensurate with the level of risk.

I'm old and taking the path that was a little more risky has proved to be quite benficial on numerous occasions. And the number of times that science has blown it is phenomenal.

 

[jreeves]

jreeves, there is no theory involved, only fact.

Atmospheric CO2 causes the earth to retain heat. We have increased atmospheric CO2 by 40% in the last 200 years. Therefore, we have caused the earth to warm.

None of the above statements is a theory.

BS it is a theory that man is causing the earth to warm through CO2 emmissions.
