What global warming? Haven't a seen a summer this bad for a long time....
What we're experiencing is the effects of that, planet warms up, ice melts in the polar caps, salinity of the seawater drops, messes with the gulf stream bringing warmer waters to us, which affects the jetstreams that supply us with warm air, so they end up blowing the wrong way, and hey presto, storms, floods, little sunshine, not the idea that people have of gloriously sunny days with Texas temperatures for most of the year with sunburn all round... ;)
That said, there are a few exaggerations when it comes to global warming though, the planet goes through cycles of hot & cold periods where the caps melt and disrupt the rest of the planet, followed by a big freeze which ends up with us under a lot of ice, so it's going to happen whether we like it or not...
But, it's still a good idea to save energy use, as it'll come in handy when the planet freezes over again...
