The US would look like it did when Al Gore's farm was overrun with mastodons and people were living in caves in Tennesse.
You mean Al moved out of the cave? ;)
The numbers I saw for the year 2007 were:
(remember, this number is an average of ocean temps, land station temps, etc. Thus, not very reliable as an indicator of CLIMATE)...........
Avg 2007:
-0.6 C
A worldwide drop of 3-5 degrees centigrade would be sufficient to trigger another ice age.
After the Toba eruption 75K years ago, worldwide temps fell by 10 degrees F.
The Earth was plunged into an ice age that lasted more than 1,000 years.
Does the Ag Dept still pay Al a subsidy for not raising mastodons any more?
