Now how did that happen without global warming?
Good point. Now, how can we cause another ice age and regain all that land mass that has been lost to Global Warming? We are going to need to make the planet cold enough for ice sheets a couple miles thick to cover North America down to about I-70. Then we'll be able to walk to Cuba and Russia and Hawaii will have another half dozen islands. Think of the real estate potential. It will make everybody RICH!
(Do I need a cynical tag on this or is it obvious enough?)
I know you are being sarcastic, but there are really a number of factors that will cause sea levels to rise.
Most specifically, some believe that earth was hit by a comet in the Canadian ice fields some 12,600 years ago. The heat and subsequent fires melted glaciers in a week. Which was followed by a brief return to an ice age.
The universe balances itself out.
What difference, at this point, does it make?
duh... wooly mammoths had a highly developed industrial manufacturing base which depended on fossil fuels. didn't you learn that in gubmint school?!
