With all the problems facing the US, I believe that global warming would be the least of our worries.
If it turns out to be true, ya know, like virtually everyone with a brain says it will, it will quickly become the number one issue worldwide. Of course, by then it will likely be too late, as it may already be.
If it turns out to be true,
IF not not a certainty. You can't make truth out of falsied documents.
What we do know for certian is that the warmmers want to control everybody's life by using a scare tatic.
