well, it's true that the end of the physical earth is supposed to occur because the sun, like all stars, gets hotter and larger as it ages, in fact right before it dies (supernova) it will be at its largest and hottest. However this can't really account for the sudden increase of temperature we're experiencing globally here since time for change in the sun is on a much more epic scale. Right now we are experiencing the hockey stick effect with temperature and greenhouse gase emissions (google hockey stick effect climate) and while fluctuations do occur naturally, people don't seem to want to respect some of the most fundamental examples of how the heat of the sun is secondary to our atomsphere. Look at mercury and venus. Who's closer to the sun? mercury. But venus is hotter because it has an atomsphere, something that mercury lacks. The reasoning is that heat radiation becomes trapped in the atomsphere longer. It accumulates. Earth's atomsphere is nowhere near as congested as venus' but the more shit that flies up into the atomsphere, the more heat from the sun is going to be trapped in. Today we combust crude oil which releases greenhouse gas (we've practically depleted a natural resource) and we cut down the trees which used to breathe in CO2 and breathe out oxygen.

its called ac its not that difficult by the way al gore mad cause he is not president in which case he'd be telling us oil companies are r freinds. what bull
I caused global warming.
Yeah, lets all believe that. We feel better, we dont need to do anything and we all melt happy (or something).
GGGGAAAAAAAAHHHHHHHHHH!!! Were all gonna die!!! X_X
Ive always felt strongly about this topic.
I often laugh at groups such as 'freinds of the earth' etc think they understand sceince? when in reality all they wanna do is be anti establismental and dance and beat drums.
Wade sir, i salute you
There have been many ice ages throughout the history of the earth. Many before man even existed. My question is; "who caused the last rounds of global warming, resulting in the end of each of these ice ages?" Did the dinosaurs release too much CO2 with their cars and factories? I know it wasn't the Flinstones; they used clean, efficient, foot power, or dinosaurs for automation and locomotion. The earth's temperature definitely seems to be linked to CO2 levels, but CO2 levels seem to be on a 100 thousand year cycle. Guess what, we're in the hot spike now.

Damn it... Graph is on the right.

We can still stop from making it hotter faster.
When people say ''We can stop it getting hotter faster though!'' It really pisses me off, sorry.
Because my theory is, if we are to look at global warming as a car going 200 mph/kmph towards a man, and our efforts slow it down by 10-15 mph we are not making much of a difference. I think our efforts are ok, not making much difference. Wasting time doing something that won't help much, if at all.
wish i could make myself say that...

wow its all very interesting
