The Last Time the Globe Warmed
Cool,
Do you think ferns and other tropical plants could extend as far north this time?
The last time saw the most prolific period of life on earth.
Embrace change and stop fighting it.
God, you are one silly idiot. That change took place over a period of 200,000 years. It took 20,000 years for the warmup. We are putting enough GHGs in the air that we can hit the amount of CO2 that was in the air in that period in about 300 years. A change that quick won't result in a tropical forest in the Arctic in that period, but it will result in the desertification of many areas that are presently cropland. People like you flap your ignorant yaps constantly without the slightest research into what you are yapping about.
