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.

This seems to be a common strategy of those who believe that 'Global Warming' has been proved to be caused by human actions.

Such people will always trot out comments about scientists with opposed views being funded by the fossil fuels industry etc., but will ignore the suggestion that anyone who claims to be a 'Climate Scientist' will only continue to find paid employment while there is a belief that there is something wrong with the climate.

I agree that we seem to be seeing some more severe weather systems.
Ice coverage of some parts of the globe seem to be decreasing (compared to some previous measures)
Climate may be changing (although I was taught in school that 'Climate' is a consideration of general conditions over a 30 year period)
If there is climate change, some of it may be due to our actions.

Due to the viewpoint (noted above) of the original poster it seems pointless to get into a debate about these matters.
