Syl, even if you take all the cars off the road and stop all emissions, it's unlikely you can stop the release of methane, and that's about 85% of the contribution to global warming.
Warming is like a stone rolling downhill, and methane release is almost unstopable once it gets going. It's a logarithmic change, not a linear one.
The earth has had many cycles of warming and cooling stages according to various studies. We've had North America and Europe covered in glaciers, and we've had a tropical climate in the Arctic.
If there's anything history has taught us its that there is no "normal" for the earth. The earth is a volatile planet with a history of huge swings in climate over alarmingly short periods of time.
I'm not saying I don't care. I'm just saying the whole debate about carbon emissions focuses on one small element of a very complex equation that may take 100-years to play out.
On the other hand, we have severe potable water shortages in much of the world, and global grain supplies are at their lowest since the early 70's. Fresh water and food are a more pressing issue in sustaining our planet's population, IMO.
The planet's not going to die because it's getting warmer. People will have to adjust. Farmers will have to adjust their crops to changing climate. People will have to stop building so close to the coastlines, in flood plains, or below sea level. People will have to move out of deserts and into less arid areas. We may have to think about a world without Venice, Italy. However, we've survived the sinking of the great library at Alexandria, Egypt a couple thousand years ago, and I think we'll adjust to whatever happens.
Canada's going to be the promised land if warming continues.
Don't think I don't care, but I refuse to get emotional about an issue that is being treated by "scientists" like Al Gore as a completely human problem.
