Today in GOP Climate Denial …

Denying climate change is de rigueur among members of the House Republican caucus. Rarely, though, do you see elected officials engaging in public debates on the science with a scientific organization. But that was exactly what has transpired as Rep. Dana Rohrabacher (R-Calif.) has taken on the Union of Concerned Scientists in a Twitter war over climate change.

Not that it’s particularly surprising. This is a guy who has argued in a congressional hearing that global warming might have been caused by dinosaur farts.

Here’s the full exchange:

.@danarohrabacher calls #climate change “natural.” There are multiple lines of evidence human activity drives it http://goo.gl/WZsdq #hcsst

@UCSUSA Guess ancient climate cycles, like current one on Mars,which mirrors changes on earth, not product of sun but of human activity

.@danarohrabacher Human warming=fact http://goo.gl/TEAhMMars warming=myth http://goo.gl/jvBD3 Sun outputs don’t=warminghttp://goo.gl/LC0TY

@UCSUSA your answer deceptive: talks Mars warming. Issue is Earth and Mars icecaps shrinking at same time. Coincidence or Solar impact?

@danarohrabacher That’s a red herring about the Red Planethttp://goo.gl/GSq6g Burying your head in the Martian sands puts us all at risk

@UCSUSA U ignore issue: incredible coincidence or solar? Whose head in sand? Read e-mails, U trust your source. Warming has become change

@danarohrabacher You don’t want to understand. Denier talking points aren’t science. Skepticalscience.com covers all this.

@danarohrabacher CA-46 is preparing for climate change. Long Beach sees water supply impact.http://goo.gl/rQQE1 Denial doesn’t help.

Here’s a quick run down of why his arguments—that global warming is caused by the sun, the climate’s changed before, and that Mars is also warming—are all bunk.

THE BIG PICTURE

You expect the big picture, and it's our job at Mother Jones to give it to you. And right now, so many of the troubles we face are the making not of a virus, but of the quest for profit, political or economic (and not just from the man in the White House who could have offered leadership and comfort but instead gave us bleach).

In "News Is Just Like Waste Management," we unpack what the coronavirus crisis has meant for journalism, including Mother Jones’, and how we can rise to the challenge. If you're able to, this is a critical moment to support our nonprofit journalism with a donation: We've scoured our budget and made the cuts we can without impairing our mission, and we hope to raise $400,000 from our community of online readers to help keep our big reporting projects going because this extraordinary pandemic-plus-election year is no time to pull back.
