After Ben Carson this week dismissed those who believe in climate change and claimed that there is not significant evidence to back it up, California Gov. Jerry Brown (D) took it upon himself to provide Carson with some reading material on the science behind climate change.

Carson made the remarks on Tuesday in response to July comments made by Brown, in which the governor called climate change skeptics “troglodytes.”

“I know there are a lot of people who say ‘overwhelming science,’ but then when you ask them to show the overwhelming science, they never can show it,” Carson told the San Francisco Chronicle on Tuesday. “There is no overwhelming science that the things that are going on are man-caused and not naturally caused.”

“Gimme a break,” the presidential candidate added.

And so on Thursday, Brown took it upon himself to show Carson the “overwhelming science” behind climate change.

The governor sent Carson a flash drive with the UN Intergovernmental Panel on Climate Change’s report on the science along with a letter urging Carson to read it, according to the San Francisco Chronicle.

Brown notes in the letter that the UN report “assessed over 30,000 scientific papers and was written by more than 800 scientists” and concluded that human beings contribute to climate change.

“Please use your considerable intelligence to review this material,” Brown concluded in the letter. “Climate change is much bigger than partisan politics.”

Brown’s office confirmed to ThinkProgress that the governor sent Carson the flash drive as well as a link to the report via email.
