Skeptics’ Last, BEST Hope?


On Thursday, University of California-Berkeley physicist Richard Muller put out his much-anticipated Berkeley Earth Surface Temperature project (BEST). Muller had been a skeptic of human-caused global warming, was highly critical of climate scientists, and was beloved by climate deniers who thought he would finally prove them right.

Unfortunately for them (and the Koch brothers, who spent $150,000 on the project), Muller’s alternative analysis of global climate data found the same rise in temperatures. It became clear a few months ago that Muller’s report was probably going to be a let down for deniers—he previewed Thursday’s results in testimony before the House Committee on Science and Technology in March. “Global warming in my evaluation is real and much of it, if not most of it, is caused by humans,” Muller said in a recent speech. Here’s what his team’s analysis of 1.6 billion temperature reports from 15 data archives looks like:

More Mother Jones reporting on Climate Desk

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
