Climate myths: Many leading scientists question climate change

It depends what you mean by "many" and "leading" - the fact is that the vast majority of scientists agree that human activity is causing warming

In fact, a recent poll found that 97.4% of active climatologists agree that human activity is warming the planet.

Climate change sceptics sometimes claim that many leading scientists question climate change. Well, it all depends on what you mean by 鈥渕any鈥 and 鈥渓eading鈥. For instance, in April 2006, signed a letter urging Canada鈥檚 new prime minister to .

This appears to be the biggest recent list of sceptics. Yet many, if not most, of the 60 signatories are not actively engaged in studying climate change: some are not scientists at all and at least 15 are retired.

Compare that with the dozens of statements on climate change from various scientific organisations around the world representing , the consensus position represented by the IPCC reports and the 11,000 condemning the Bush administration鈥檚 stance on climate science.

The fact is that there is an in the scientific community about global warming and its causes. There are some exceptions, but the number of sceptics is getting smaller rather than growing.

In January 2009, found that 82% answered yes to the question: 鈥淒o you think human activity is a significant contributing factor in changing mean global temperatures?鈥. Of the 77 climatologists actively engaged in research, 75 answered yes (97.4%).

The scientists were petroleum geologists and meteorologists.

Of course, just because most scientists think something is true does not necessarily mean they are right. But the reason they think the way they do is because of the vast and growing body of evidence. A looked at the abstracts of nearly 1000 scientific papers containing the term 鈥済lobal climate change鈥 published in the previous decade. Not one rejected the consensus position. One critic promptly claimed this study was wrong 鈥 but later .
