Since when is zoologist Matt Ridley  an expert on climate change science?
Yes, I get it. The state of science versus opinion is at an all-time low in human history, with perhaps the Dark Ages the only exception.
There is currently a “debate” being led by Matt Ridley (you can read all about Ridley's complete lack of credentials in the field of climate science here ) brewing in the right wing press about a possible “subtle drop”  in the low end prediction of how fast global warming is occurring. Ridley's quibbling comes, not coincidentally, less than two weeks before the release of the latest report from the Intergovernmental Panel on Climate Change (IPCC) , a favorite whipping post of the climate denier echo chamber.
Ridley and his pals at the Global Warming Policy Foundation  have taken to the airwaves and the right-wing tabloids ahead of the official IPCC release date to try and pre-emptively discredit the IPCC's conclusions. It is a classic political move to get out first and fast before your opponents have a chance to tell their side of the story.
What they want to do (again) is create the appearance of controversy and debate to generate headlines and the perception that climate change science is not as solid as scientists say it is. Doubt is their product .
Hopefully the mainstream media will look past the thin veneer of credibility of Matt Ridley and the Global Warming Policy Foundation, and instead speak to actual climate scientists instead of an expert on animals. The issue of climate change and the state of the science is too important to leave to rookies.
As for what is actually contained in the IPCC report, as one real live and trained climate scientist, Dr. Andrew Weaver, told the National Post :
“What we’ve learned since 2007 is not a lot of new stuff. It’s basically underscoring with greater certainty what we’ve already said. To capture it in a sound bite, it’s essentially more of the same, with a little more certainty…. Scientists have done their job. Now it’s time for policymakers and politicians to do theirs if we as a society want to deal with this problem. Here we are, in 2013, with another massive report. It’s just saying the same thing.”
In other words, the news is just as bad as it was the last time the IPCC issued a report, no matter how many amateur experts want us to think differently.
