I'm not a denier that the earth is getting warmer. But sometimes I wonder if humans could do anything about it at all? We are still in an ice-age, and the earth goes through cycles of ice age and non-ice age.
Could this global warming be the tail end of our current ice-age? There have been ages in earth's past with no ice at all long before humans existed. I'm not saying we shouldn't be environmentally responsible, (i.e.: don't dump your oil into the sewer when you change your oil), but how much can humans realistically do when the earth decides to change ages?
