Washington (CNN)Ben Carson says there's no convincing research to prove that man plays a role in climate change.
So California Gov. Jerry Brown has sent the retired neurosurgeon a U.N. report so he can brush up on the subject.
In a letter Brown sent to Carson on Thursday, he cited comments the Republican presidential contender made to the San Francisco Chronicle this week in which he said, "There is no overwhelming science that the things that are going on are man-caused and not naturally caused. Gimme a break."
But Brown, a Democrat, cited this summer's lengthy drought in California as one example of what he said was humanity's role in climate change, and even included a flash drive containing a report from the United Nations Intergovernmental Panel on Climate Change.
The letter ends with Brown writing, "Please use your considerable intelligence to review this material. Climate change is much bigger than partisan politics."
When asked to comment on Saturday, Carson's campaign communications director Doug Watts said the candidate had not yet received the letter. But Watts maintained that Carson is not a "climate denier" but what he called a "climate questioner."
"He has a different standard of persuasion and proof. Nothing more," Watts said. "He questions (climate change) and cares about the environment."
Watts said Carson would read the report with an open mind when it arrives.

The unfortunate truth is that it is indeed very difficult to prove conclusively that any specific weather event is directly caused by climate change. It is much easier to show that trends or an aggregate series of events are consistent with climate change models.
And here we actually have two real problems with science education: on the one side, clearly a lot of people don't really understand science or the scientific method. But on the other side, we have scientists who are taught through and through not to make claims that they can't support with data, which is great when you're talking to another scientist but results in a world crisis like climate change when you're trying to inform science policy. (I know, the other solution would be to get politicians to stop being lying liars who lie, but that seems a lot less likely to come to pass than either of the first 2 options.)
