James Hansen

I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear.

And you know, I said yesterday, you know, you know, if they're not going to - if the feds aren't going to do their job, well, then, I'm up to suing the feds to make them do their job! I mean, they sued Arizona, you know, we can sue them back! I mean, they're not - they're not enforcing the laws!
