I heard that CO2 level have been dropping for a very, very long time and look to continue to decline as carbon is sequestered at the bottom of the ocean. I ask because this is not my area of expertise, and I was hoping that someone who is more of an authority might be able to comment. The researcher whose perspective I am parroting here used Hawaii as an example, pointing out how the massive rainfall and runoff causes carbon to be washed deep into the ocean. It was enough to cause one to wonder about the future of plants! LOL! This might all be more junk science, but I thought that it was ironic. Ah well, let's have some pie.

Isn't water vapor a stronger greenhouse "gas" than carbon dioxide?

Is anyone asking the Fuel Cell people about this?
