"Anybody who starts a discussion with a heading such as:
"It's global warming, stupid!"
is immediately, and unconditionally, refusing to accept that any contra arguments may have any merit. As such, to attempt to put any reasonable arguments (unless they support the original posting) is pointless."

First of all, the statement comes from New York's Mayor Bloomberg. Second, there are no reasonable contra arguments that have any merit whatsoever. This is a crucial issue and supposed "contra arguments' are given mainly by Global Warming deniers who work for energy companies. It's a clear cut issue and is obscured by those who have a corporate agenda, usually paid "science shills" to obstruct information on this issue.
