Lets Admit that the little ice age was very unfavorable period for sustaining a billion plus humans and in fact the human population didn't grow above 1 billion until 1803 or near the end of this hellish period. Since then our ability to grow food has increased enough to feed up to near 7 billion humans and we're all much more happier for it. Life was also better before the little ice age within the Climate optimum and Med evil warm periods. These periods of great advancement from the first farming to the city and nation state...So There is a to cold and Maybe to hot too...I'm not saying the warmers are wrong to worry and in fact our good luck with a warming planet could run out sooner or later...As there is always to cold and to hot. So hopefully the warmers will agree that todays world is much more able to feed our population than the little ice age of 1300-1850, but to our skeptic friends there is of course a limit when some of the land we currently use could become too hot to grow food too. Which could limit us. So it is a balance. 2c of warming if we where to warm that much within the next 100-150 years would likely move our growing area's some...At least you would think. So warmers would you admit that the warmer world up to this point is better then what we had to deal with two centuries ago? And skeptics would you admit that there is a limit to how warm it could get before things could change in bad ways.
