Another thing has been learned the hard way in the Amazon Valley. I think there might be a similar problem in northern forests.<quoted text>
A couple of problems....warming changes weather patterns, which may leave previously fertile areas colder or in drought status while opening up other areas which weren't open to agriculture. This could be an even trade, but will disrupt societies and politics.
Second, and much more significant, it WILL leave world sea levels higher, possibly MUCH higher depending on how warm it gets. Several feet would flood all low-lying coastal areas leading, again, to massive social and political disruptions.
And there's the distant possibility that RUNAWAY warming could make the Earth uninhabitable, the 'Venus effect.'
Not sure this is something we want to gamble with...
You can't just clear cut jungle and convert it to pasture or farm fields overnight. IT'S JUNGLE SOIL! It has been a part of a single ecosystem for millennia. To convert it would require converting the existing soil into another kind of soil, as well as adding megatons of fertilizer.
"Adapting deniers" are simpletons who think any part of the world can bend to human will with no problems.
The environment is unbelievably complicated, and not nearly as simple as an unmitigated idiot mistakenly thinks it is.
