I'm hoping someone that knows a thing or two about these issues comes along to the forum. I'm just curious if anyone has done any studies to determine just how long man could survive on the planet if the temperature rose say 10 degrees. What's the point where man just no longer can sustain life? I figure most the creatures on the planet would suffer first as man can adapt pretty well. Would the animals be smart enough to migrate to a cooler climate as the worlds heat zones shifted ?
