1. NOT the whole world is heating up. It varies and some places are cooling, but no, generalise. 2. Areas like Russia and upper Asia will provide more arable land, these countries will experience a boon 3. The problem isn't the world, the problem is the sky high population growth in Africa/Middle East. Google "Population of ANY AFRICAN/MIDDLE EASTERN COUNTRY"

I think everyone wishes you could be correct but the situation where tundra/permafrost areas warm to a point that it is possible farm would cause a catastrophic release of Carbon on par with direct human activity.

Incorrect, The whole world is heating up except <0.1% habitable area, definitely not enough to make the statement above incorrect

But the problem is, as you go further from the equator, you get less square miles per degree of latitude. So if we lose arable land around the equator, and gain it in Siberia, that's still a net loss of arable land.
