Climate change report is devastating, but skeptics see a conspiracy

By George Monbiot  /  The Guardian, LONDON

Already, a thousand blogs and columns insist the Intergovernmental Panel on Climate Change’s (IPCC) new report is a rabid concoction of scare stories whose purpose is to destroy the global economy. However, it is, in reality, highly conservative.

Reaching agreement among hundreds of authors and reviewers ensures that only the statements which are hardest to dispute are allowed to pass. Even when the scientists have agreed, the report must be tempered in another forge, as politicians question anything they find disagreeable: The new report received 1,855 comments from 32 governments, and the arguments raged through the night before launch.

In other words, it is perhaps the biggest and most rigorous process of peer review conducted in any scientific field, at any point in human history.

There are no radical departures in this report from the previous assessment, published in 2007; just more evidence demonstrating the extent of global temperature rises, the melting of ice sheets and sea ice, the retreat of the glaciers, the rising and acidification of the oceans and the changes in weather patterns.

The message is familiar and shattering: “It’s as bad as we thought it was.”

What the report describes, in its dry, meticulous language, is the collapse of the benign climate in which humans evolved and have prospered, and the loss of the conditions upon which many other lifeforms depend. Climate change and global warming are inadequate terms for what it reveals. The story it tells is of climate breakdown.

This is a catastrophe we are capable of foreseeing, but incapable of imagining. It is a catastrophe we are singularly ill-equipped to prevent.

The IPCC’s reports attract denial in all its forms: From a quiet turning away — the response of most people — to shrill disavowal.

Despite — or perhaps because of — their rigors, the IPCC’s reports attract a magnificent collection of conspiracy theories: The panel is trying to tax us back to the stone age or establish a Nazi or communist dictatorship in which we are herded into camps and forced to crochet our own bicycles. (And they call the scientists scaremongers.)

In the Mail, the Telegraph and the dusty basements of the Internet, the report issued on Friday last week (or a draft leaked a few weeks ago) has been trawled for any uncertainties that could be used to discredit. The panel reports that on every continent except Antarctica, man-made warming is likely to have made a substantial contribution to the surface temperature. So those who feel threatened by the evidence ignore the other continents and concentrate on Antarctica, as proof that climate change caused by fossil fuels cannot be happening.

They make great play of the IPCC’s acknowledgment that there has been a “reduction in surface warming trend over the period from 1998 to last year,” but somehow ignore the fact that the past decade is still the warmest in the instrumental record.

They manage to overlook the panel’s conclusion that this slowing of the trend is likely to have been caused by volcanic eruptions, fluctuations in solar radiation and natural variability in the planetary cycle. Were it not for man-made global warming, these factors could have made the world significantly cooler over this period. That there has been a slight increase in temperature shows the power of the human contribution.
