Is it ok to make fun of Global Warming?

I dont know it seems like no one is taking Global Warming seriously... I know its real and am trying to do everything I can to contribute to fixing the problem.

But have a look at this commercial from Australia... it's pretty out there... (for those of you Aussies - it has Emma from Big Brother 2007 )

Don't you think this makes the whole problem seem so trivial... ? Someone tell me I'm wrong!
