Study says skeptics are not well-informed on the topic

Stanford University recently conducted a study that shows a minimal number of scientists who do not accept that human beings have contributed to the Earth's climate change have "far less expertise and prominence in climate research" than scientists who do believe climate change has been affected by humans. 

The university came to these conclusions by analyzing the number of research papers published "by more than 900 climate researchers" and the number of times these researchers' works were cited by other scientists. The expertise was evaluated by citing the number of research papers written by scientists (with the minimum number for inclusion being 20).

Prominence was analyzed by finding the four most popular climate change and non-climate change papers published by scientists, and "tallying" the number of times these papers were cited. According to the results, approximately 64 percent of papers by climate researchers convinced of human contribution were cited more often than those who are unconvinced. 

"These are standard academic metrics used when universities are making hiring or tenure decisions," said William Anderegg, lead author of a paper published in Proceedings of the National Academy of Sciences.

The scientists who participated in the study were also involved in creating the 2007 report of the Intergovernmental Panel on Climate Change (IPCC), which compiled and "assessed the evidence for and against human involvement in climate change, as well as any climate researchers who signed a major public statement disagreeing with the findings of the panel's report."

In addition, the university's team of scientists decided on who the top 100 climate researchers are by determining the "total number of climate-related publications each had." According to Anderegg, 97 percent of those in the top 100 agree with and/or endorse the IPCC's assessment. He also says that this result has been "borne out" by other studies that use different methodology.  

"We really wanted to bring the expertise dimension into this whole discussion," said Anderegg. "We hope to put to rest the notion that keeps being repeated in the media and by some members of the public that 'the scientists disagree' about whether human activity is contributing to climate change."

The scientists at Stanford have mentioned that they are ready to take some heat from doubters of anthropogenic, or human-affected, climate change who "object to their data." But according to Stephen Schneider, a professor of biology and a coauthor of the paper in Proceedings of the National Academy of Sciences, the team "took pains to avoid any sort of prejudice or skewed data in their analysis." When selecting researchers for the study who either disagreed with statements of the IPCC or signed the petitions, the Stanford team was sure to stay completely neutral in the study by omitting "those who had no published papers in the climate literature."

Schneider says that despite the careful analysis of this study, skeptics of human-affected climate change will "claim foul" anyway, and will say that climate researchers who are onboard with the idea of anthropogenic climate change are "just trying to deny publication of the doubters' opinion," but he challenges them to "go out and do a study to prove it -- it is of course not true."

"I think the most typical criticism of a paper like this -- not necessarily in academic discourse, but in the broader context -- is going to be that we haven't addressed these sorts of differences could be due to some clique or, at the extreme, a conspiracy of the researchers who are convinced of climate change," Anderegg said. 

"When you stop to consider whether some sort of 'group think' really drives these patterns and it could really exist in science in general, the idea is really pretty laughable," he said. "All of the incentives in science are exactly the opposite."

This Stanford study is the first of its kind to address the issue of scientists' opinions of human-affected climate change, and what their level of expertise and prominence in the field is.

Also their models are based on the supposition that co2 is what's causing the warming. That was confessed on a PBS special by someone who worked to develop the model back in 82 I think it was. It worked for a while as long as the amount of co2 produced increased and the average temperature increased... but the temps have gone down in the past decade while co2 production has increased!

We just had the coldest summer on record a couple of years ago but you dont see that in the media because it doesnt fit the headline that the prophet Algore was right and we are killing mother earth. We are being lied to by the 60's and 70's hippies who are now grown up and put on a suit and ran for congress. As someone else said earlier the reason they are pushing for the cap and trade is power.

When you have a global government dictating how much co2 you can produce what's to stop them from limiting you to 1 hybrid car per household? Why stop there why not just say only x number of cars can be sold in each country? Then we have cap and trade for car purchases and the global government can claim that "this will go a long way to curbing global warming" when in reality all it will do is price the poor people out of the car market and jack up prices of everything all over the world.

Central planning is one of the tenants of a totalitarian regime and if the central planners can rally around a "moral issue" such as global warming then anyone who opposes their controls and caps is the enemy or immoral.

This is the basis behind the non-scientific political agenda that is entangled with the debate on global warming. There are scientist on both sides that have valid arguments, but the side that gives the politicians power is the one that will be promoted the most in public. And even if you don't believe in the more sinister prospect of governments wanting total control of the people, there is the more benign fact that government leaders feel threatened when faced with something that is beyond their control. It makes them look weak to their citizens.

If mankind is the driving force behind global warming, then governments have some control over it. If it is a totally natural occurrence then governments really have no control over global warming and they become powerless to stop it and thus look weak. If you want a good example of this just look at the oil spill in the Gulf of Mexico. The government can blame BP and make a show of doing something by punishing them for it. Had it been a natural blowout in the sea floor and they were as powerless to control it as they have been so far, they would be ridiculed as totally incompetent and impotent as the government was after Katrina. Even in Katrina the governments did not want to start out saying "OK we have work to do" they just wanted to be able to blame someone for what was an act of nature beyond anyone's control.
