Less "big winner" and more "least losers". Very much a "I'd rather be a king in hell than a beggar in heaven" kind of things.
Climate change will alter what latitudes crops can be grown in, but between the more erratic climate patterns (which make it harder to grow crops at all) and the absence of any built-up quality soil high up, it will mostly lead agricultural output to drop precipitously.
Heavy subsidence from melting permafrost and cratering from methane explosion won't help either.
And then, obviously, modern industrial agriculture is not just a bloke going out on a field and throwing a few seeds they found in their pantry or in a rock crack, there's an entire chain of supplies and knowledge undergirding it.
> China seem to be the big winners of climate change.
Have you ever looked what altitude China's major population and agriculture centers are? The north china plain is barely 50m above sea level at its highest point.
Now that doesn't mean it can't be leveraged e.g. the CCP may well be planning to use this in order to, say, declare emergencies, draft everyone and prosecute massive expansion wars, but I wouldn't say "China" in the sense of its people would be a big winner of that.
"Winners of climate change" is pure propaganda talk and if you read basic literature about what 2 or 4 degrees more even means you will have a better understanding for that and it will enable you to dismantle that fabricated idea.
The region I grew up in, in eastern Ontario, is an area with fairly thin soil. Fortunately, summer rains were generally frequent and mild- light rain all day a few days per week, and sunny and warm otherwise. This balanced out the thin soil, and made it work well for certain crops, corn especially.
The last 15 years have seen a huge shift to dry weather interspersed with dramatically heavy rain. Heavy rain sounds good, but it's too fast- the water doesn't seep deeply into the soil, doesn't let the crops really get a good drink. It runs off, often taking nutrients with it straight into rivers.
My parents are saying their farmer friends, staunch conservatives who used to believe climate change was a political stance, are suddenly getting more and more worried.
This whole ordeal is a lesson in fucking yourself over… Making up your own "thruth" may work for some things, but does not for most.
