Warthog keep your conspiracy theories to yourself. Yes, global warming is a bit of an inappropriate phrase - as some environmentalists are now calling it "global weirding" is a more appropriate phrase. It doesn't mean that it doesn't exist. It just means that the old phrase was not a very good one, and now we have a better phrase to describe it.
Global warming / weirding does not mean that everywhere temperatures are rising, but that in some places they are dramatically rising, and in some places they are dramatically decreasing. Same goes for rainfall patterns, tornadoes, tsunamis and other weather / climactic patterns.
One problem is that rising temperatures in the ice caps is leading to a depletion of the ice caps and a consequent rise in the sea levels world-wide (which means more tsunamis and more land coming under water).
Anyone who claims that the climate / weather is not changing dramatically has completely lost it. I remember that when I was a kid (not that far back - about 15 years ago or so) - monsoons in Delhi meant monsoons, i.e. 4-5 days of non-stop rainfall. Now monsoon here means rain for 2-3 hours a day for 3-4 days within a week. That's a huge difference. Not to mention it's getting hot as balls here than ever before (part of it can be explained by our rising dependency and habituation to air conditioners etc. but there is undeniably a change).
