How well can humans adapt when the climate changes (coastal areas underwater, rivers flood, fertile land does not get rain)?
Just fine thank you very much.
Humans are the masters of adapting and surviving. I have no doubt that even if the very worst predictions of the global warming alarmists comes true the human race will survive. And prosper. Oh there will be a thinning of the herd, possibly myself included in that number. But do we really need or want 7,8,9 billion or more humans? By environmentalists own words we are the problem.. well then we are also the solution, a self correcting one. Like bacteria that bloom in a petri dish when food is added, then most (but not all) die off when the food supply is exhausted.
Besides evolution and Darwinism requires some to fail, if there were no failures there would be no evolution.. Dinosaurs would still roam the earth. Stop trying to prevent change. Change is good in the big picture, even if bad in the small.
If you are so worried about it, move to Greenland where you will benefit from the coming changes.
