What do forests have to do with growing food?

I don't know. I was thinking maybe you were suggesting something along the lines of boreal forests becoming suitable land for food growth with warmer temperature.

Humans regulary cut down forests for agricultural use.

And the slash-and-burn agricultural paradigm in the Amazon may be turning off our planetary oxygen generator. It's certainly releasing carbon that has been stored in the forests. Instead of trees a hundred feet high and associated jungle growth we get 1-2 seasons of grain products. Then the soil is exhausted and incapable of renewing itself because the ecology is wrecked by humans.

BTW, "pulp farms" are very unlike "old growth forests".

All forests are oxygen neutral.

Modern technologies can replenish nutrients in soil

So cut down forests and turn them into arable lands and this effectively combats climate change is what you're saying?

Yes, other than relocating some people from islands in Pacific Ocean there is no real economic harm.

So two problems you're not noting here:

Not all countries contain boreal (or other cold enough) regions that you naively believe can be made arable with warmer temperature. And even in countries that do, that may be a small percentage. IOW, how is Canada going to be of much help to countries, say, along the Equator?

To be arable, there needs to also be adequate supply of water. IOW, not so dry as to not be able to promote food growth.

I know there are a lot of other factors involved that you're missing/overlooking, but I'll let the more knowledgeable people expound on those.

Canada can export food to those countries.

Shouldn't air become more humid because of higher temperatures?

No ... The effects of climate change include a drier climate.

From the link I posted earlier:

Quote:The rate of the changing climate is leading to drier conditions in the boreal forest, which leads to a whole host of subsequent issues.

ETA:

I should rather say that it's not necessarily going to be more rain. Depends on various factors at hand and where in the world, the effect could be something like increased droughts or heavier rainfalls.
