What do you like about this subject?
It is so interconnected with every other subject--it is mostly science, but it also involves a bit of economics, politics, history, humanities--everything. I also believe that becoming well educated about the future of climate change is critical to humanity's progress.
Something interesting about this subject that others may not know:
It really doesn't have much to do with nature. So many believe "the environment" is something separate from humanity. That global warming is just about polar bears. It isn't--I couldn't care less about polar bears. By far the biggest danger about GW is its effect on the economy.
Something controversial or provocative about this subject
Is there any other topic out there that is *more* controversial than GW?

Ah, sorry I understand now. There are two ways you can talk about this: either the weight of CO2, or the weight of carbon. Both of them are indeed based on the molecular weights. As you can imagine

Hi Laura, The specific techniques of measuring CO2 are not my expertise, but hopefully my limited knowledge will be of some use. There are of course estimates out there of the amount of fossil
2009-09-01 CO2-induced global warming:
Hi, I'm not quite sure what you mean by "full cool year". But just because CO2 is the primary driver of the recent global warming, this is not to say that CO2 is the only factor in determining Earth's

Hi James, You have fallen under a very common misconception about the ozone layer, and that is that the ozone layer is some kind of big, solid bubble above us in our atmosphere. The truth is, if you

Hi David, Take heart, you're not as confused as you think. The main danger from running your car in the garage is indeed other gasses and not CO2, the most important being carbon monoxide (CO).
