The climate change debate has been shunted into a whole variety of tangents, but one of the most pointless is the debate over whether or not the debate is over – is there a consensus or not?
The IPCC process, while not perfect, was the one of broadest and most thorough reviews in the history of science. The Royal Society and the US Academy of Sciences have conducted their own reviews and agree. Science Magazine conducted a survey of published papers, and out of 928 peer-reviewed papers on climate change between 1993 and 2003 there wasn’t a single one that disagreed with the IPCC’s opinion.
And that’s what it comes down to: where exactly are we looking for the consensus? Obviously there are dissenters and people with alternative theories. Ultimately though, what matters is a consensus among the people most likely to know and understand the science. You can forget the bloggers, question the journalists and take the politicians’ opinions with a pinch of salt, but what do the scientists say? More specifically, what do the earth scientists say? And within that group, what to those who study the climate think?
Here are the results of a survey of earth scientists that the University of Illinois in Chicago released this week. Climate change scientists are almost totally in agreement that human activity is producing global warming. Meterologists are less sure, but there is still a majority opinion. There isn’t a consensus among petroleum geologists, but considering their jobs are at risk if climate change is happening and questioning it is in their interests, 47% is pretty high. Across all earth scientists, 90% agreed there had been a temperature rise, and 82% agreed that human activity was a ‘significant factor’.
Given this, why on earth isn’t there a consensus among the public? Why do we think we know better than the scientists?

I agree that some of the news media can give far too much attention to the very small minority that disgree with hard scientific evidence.
In the past this was a useful way to keep the topic in the spotlight, but now with so many media organisations putting global warming at the forefront of programming, it is time we started to show up these “alternative” views for what they are…..normally paid interests.
Its time we spoke us one, the silent majority, needs a voice !
I think you’ve misunderstood. There is no hard evidence! All the climate change so called experts have a vested interest in being right. All the evidence they have is circumstantial and not hard evidence. There is no proof that human activity is heading the planet into destruction, this is scaremongering and aids the government into ripping off the public in the name of saving the planet. Not one scientist can actually prove that anything we are doing is causing climate change. If you go back in history you will see that it has happened many times before and we are on the way up to another peak before temperatures start to fall again. Scientists tried to tell us that the ice cap has never melted before and that it is a catastrophe that we are causing it to melt, then that claim was debunked by the finding of an ancient village under the ice proving that the ice was not always there. Please do not mistake a collusion and agreement among scientists mean it is factual or supported by any kind of real evidence.
all that said, I am a supporter of genuine moves to make the planet a cleaner place to live, just not in forcing the public to pay through the nose for it and line the pockets of big corporations and governments.
Because, over all, the public is eager to swallow any explanation that leaves us all blameless. We can proceed with our gluttony guilt free.
Thank you for the very interesting information on the more educated consensus.
Visitors might be interested to read the exchange I had with Jeremy here: http://makewealthhistory.org/2012/07/21/what-we-learned-this-week-133/#comment-19016. And then to decide whether or not the above graph (indicating that 97% of climate scientists agree that human activity is causing climate change) is an accurate representation of the University of Illinois research.
Yes, please do. I have nothing to hide.
