The Competitive Enterprise Institute will be bestowing the Julian Simon Award on Steve McIntyre and Ross McKitrick for their efforts in debunking Mann's hockey stick at CEI's 2010 Dinner, June 17 at Hyatt Regency Capitol Hill 400 New Jersey Ave. NW Washington, DC 20001.
Wouldn’t earth 4 billion years ago have been quite a bit warmer on the inside? Like a pie fresh out of the oven? That would have made the crust warmer as well.
Gortex.
An additional greenhouse effect would not have been enough to keep the Earth from turning into a complete iceball.
There had to be lower Albedo (reflectance of sunlight) by clouds / atmospheric gases as well.

Thanks neverdem.Dial back the clock nearly 4 billion years, to a time called the Archean, and the sun would appear about 30% dimmer than it is now. That's a problem: It couldn't have warmed Earth enough to keep the seas from becoming permanent ice sheets. Yet overwhelming geological evidence indicates that liquid water has existed on our planet since the seas formed more than 4 billion years ago, even during the deepest ice ages.To all -- please ping me to other topics which are appropriate for the GGG list. |

I see no mention in this article of the other greenhouse gases; namely methane, ammonia or water vapor.
The solar models also have a lot of variability. They predict the sun was anywhere from 30% to 75% less bright. Maybe they’re wrong.
CO2 is one of the weakest greenhouse “gasses” out there... its a joke that folks are worried about it. ARGON is worse, and the worst culprit of all responsible for 90% of all greenhouse effect? Water Vapor!
The whole CO2 thing is just laughable.
Why are they only looking at the atmosphere for the answer, it could just as well be changes in sunspot activity or intensity of the sun....
Another scientist pointed out that the theoretical relationship between greenhouse gas concentration and surface warming (given a constant sun) is logarithmic, not linear. Doubling the concentration of greenhouse gas does not double the warming effect. That’s why they’d need so vastly much more CO2 than we have today to make up for a mere 30% weaker sun.
