The Peer-Reviewed Science of Climate Change

From the always-good Bad Astronomy:

To me, one of the most fascinating aspects of climate change denial is how deniers essentially never publish in legitimate journals, but instead rely on talk shows, grossly error-laden op-eds, and hugely out-of-date claims (that were never right to start with).

In 2012, National Science Board member James Lawrence Powell investigated peer-reviewed literature published about climate change and found that out of 13,950 articles, 13,926 supported the reality of global warming. Despite a lot of sound and fury from the denial machine, deniers have not really been able to come up with a coherent argument against a consensus. The same is true for a somewhat different study that showed a 97 percent consensus among climate scientists supporting both the reality of global warming and the fact that human emissions are behind it.
Powell recently finished another such investigation, this time looking at peer-reviewed articles published between November 2012 and December 2013. Out of 2,258 articles (with 9,136 authors), how many do you think explicitly rejected human-driven global warming? Go on, guess!
One. Yes, one. Here’s what that looks like as a pie chart:
Huh. Here’s the thing: If you listen to Fox News, or right-wing radio, or read the denier blogs, you’d have to think climate scientists were complete idiots to miss how fake global warming is. Yet despite this incredibly obvious hoax, no one ever publishes evidence exposing it. Mind you, scientists are a contrary lot. If there were solid evidence that global warming didn’t exist, or that CO2 emissions weren’t the culprit, there would be papers in the journals about it. Lots of them.
It's called science, people.  Not decided in the court of public opinion or popularity, but in the peer-reviewed research of scientists.
