I think the beginning of the end was about 5 million years ago.
OK, well not forgetting that, even though this particular period is proceeding rapidly, global warming and cooling is a cycle on a scale too huge for mere humans....
Holy crap.......good thing we're 1080 feet above sea level and 125 miles from the nearest Great Lake......better move some furniture to the second floor, just in case. Now if only we could get palm trees to grow around here..
Holy crap Beerman! I'll need you help getting the piano up the stairs...
Palm trees?? There's a chance we won't have to move south????
(I like palm trees...)
It was the beginning of the end when those fools ate the apple
True, the earth's temperature is cyclical, but humans are not as "mere" as we may think(yes, improper adjective usage). We do have the power to interupt the earths natural cycle, and the worst is yet to come. I remember hearing that it takes roughly 50 years for CFCs to reach the atmosphere, so we havn't even seen the full effect of what we have done, considering that automobile's havn't been used full force till around 50 yrs ago.
And now Prez. Bush doesn't even want to partake in our(mankinds) feeble attempt to curb the impending problems(Kyoto agreement). Even if the Kyoto agreement would be costly, and maybe wouldn't even accomplish much, we(America) should still back the first international recognition of this problem. Recognizing the problem's seriousness is the first step in a long road to reform.
It is very true that the flux of global temperatures are over such as time scale hard for us to imagine, and even harder for us to imagine us having an impact. But I think that comes down to a basic way-of-thinking that permeates our society - Us & now. People think about the future as far as they are concerned, and even then to a small extent.
Carbon dioxide levels are now 27 percent higher than at any point in the last 650,000 years, according to research into Antarctic ice cores published on Thursday in Science. -- Cited from mongabay.com
But let's say that we are taking ourselves too seriuosly, and that we really have no effect at all on the global environment, would that then exuse our apathy?
