Calling global warming denial is "mental disorder" is probably a bit much, but it is pretty bizarre that some people would rather listen to a small minority of Republican leaders than the overwhelming scientific evidence.
If you deny it exists then you can justify avoiding making hard choices.
Lets face it, the global warming crowd is merely the pretext to support their desire for bad choices.
They want more, and more government regulations, and less and less freedom.
Not suprised Lunar is part of that crowd.
