It sounds a lot to me like NASA is just re-visiting old news.

Global dimming has been known about for quite awhile, and our “clean air policies” are actually causing more sun to hit the earth then in the 70’s. So we are heating up even faster.

C02 is still the gas that keeps our earth’s heat from radiating back out into space.

But for NASA to say that the ice caps aren’t melting because of C02 but because of an increasing amount of sun hitting the planet seems really stupid. Heat, not just sun melts ice.

500 year ago, before particulate matter in the atmosphere was a big deal, our planet got the same amount of sun per day, as it does now…why weren’t the ice caps melting then??

Us humans are a weird bunch, way back in the Cretaceous period, nearly everything died because either an asteroid impact or heightened volcanic activity. The Earth’s global temperature rose to a much higher temperature then we are at now, the ocean’s were about 17 degrees (C) warmer.

Almost everything on the planet died, all of those critters and plants trapped the C02 (after millions of years) into the ground in the form of coal, oil, natural gas etc.

So the earth “recovered” (over millions and millions of years) and it stored all of these C2 sinks all over the world, and what do we do? Over a period of 150 years we manage to dig up and burn up over half of these “sinks”. Re-releasing all of that C02 back into the air, we all need to give our heads a shake and look at what we are doing.

I feel back for the “kids” who have to clean up this mess, hopefully I will be off the planet before all of the fish in the ocean are dead :\.

I just don’t get why some people can’t seem to admit that C02 is
a problem we cannot ignore, it seems NASA wants to ignore it as well…/boggle
