From what I can gather from your post, your view is that Global Warming is a myth and it's just the media blowing everything out of proportion like they always do.
Global warming is very real, and is a very real problem. It may mildly affect us in our lifetime, but the future is rather important to a fair few people. You cannot deny that global warming is happening right now, and if you're saying "there's no irrefutable evidence" that we're wasting so much energy that we're risking killing off our own race, then you've been living in a cave for the past 20 years.
It's easy to play the sceptic, and say things like "that flood would have happened anyway", but the fact of the matter is, there's more proof to show that global warming is causing an increase in extreme weather and temperature rises than there is to prove that it's normal. You use the word fluctuation when it appears you don't know what it actually means. Our weather patterns aren't fluctuating, they're showing a very easy-to-follow trend. The planet is getting hotter year upon year, this is a fact. This plays havoc with our planet, also a fact. Carbon dioxide produced today will stay in our atmosphere for 100 years, and this is the cause.
Obviously we will have hot and cold years. This is weather variability, and is true for most statistics. However, when you take the overall weather patterns for our planet over a longer period of time, you can clearly see that our climate is changing at an unprecedented rate, and global warming is the reason why. We consume a horrendous amount of energy, and our CO2 emissions are at an all-time high, and climbing. Do you think this is having no effect on our planet at all?
I suggest you watch a few programs on global warming, take off your "I hate Al Gore and the media" hat and educate yourself on what is fact and what is fiction. The media over-emphasize and exaggerate everything, but the underlying problem still remains. The only thing really up for debate is the time periods we're working with, and how much we need to cut down by. That, and the fact that the media make it out like we're killing our planet. We're not - we're killing off the human race. When our world becomes inhabitable, the earth will remain, and after a long enough time, it will return to it's normal climate; without humans.
