OK, the differance between continental glaciers and interglacials is 100 ppm of CO2. There have been a number of swings in CO2 in the last 2 million years. When it was about 180 ppm, we have continental glaciers. When it was about 280 ppm, we had interglacials. Now it is at 400 ppm, and we are seeing rapid changes. Changes in the cryosphere, changes in the oceans. The last time the CO2 was this high, there were no polar caps.
Now we really don't know how this will play out. Thus far, the models we have used have been far too conservative. The glaciers and caps are losing ice far faster than predicted, and the ocean rise is also faster. Just denying these facts will hardly change reality, only paint those that do as fools.
Is it the Sulfur Dioxide that our cars and corporate smokestacks are putting up?
The deniers are saying that it isn't us that's doing it. They say that volcano's put up more than we do. Please explain to them how/why/where they are wrong.
I watch the shows on PBS and it seems the science is in. It is very clear we are causing the problem. But when one party and half the country and the corporations and their media conglomerates are hiding/denying the truth....
