Anyone who knows anything about history knows that which crops are grown where changes over time. It has never been static.

Snyone who knows antthing about history knows that cities burn every now and then. Its natural, therefore good for you

Canada, Russia and China seem to be the big winners of climate change. It will be interesting how that changes geopolitical dynamics.

There will be no winners of climate change.

Oh, there are already winners for the past 50 years when you look at all big oil companies.

This year German farmers grew watermelon for the first time (outside of a greenhouse)

We are growing watermelons for years in our garden in Germany. And how does this fit to the fact that Germany has the coldest year for a long time? edit: wtf are you downvoting? Dumb af, look up the figures.

It isn't cold. The weather just is miserable. But the average temperatures are still pretty high and way higher than in a bad summer in the 80ies. While I didn't especially appreciate the weather here this year, my plants have been growing like hell, they like the wet and not too cold.

just because it's possible does not imply that it's viable at a commercial scale. i guess the point was, that this has changed.

likewise the average temperature over the year does not neccesarily depict climate in the vegetation period.

Yes. People have laughed but my vineyard in Sitka, Alaska will soon be producing world-class Cabs.

> People have laughed but my vineyard in Sitka, Alaska will soon be producing world-class Cabs I had this discussion with a previous CEO at a company I worked for here in Sweden a few years ago: he (being a type-A personality, and also loving fast sports cars) was very upbeat about global warming, and saw it as an opportunity to take over the Mediterranean role of growing grapes, olives and other foods that needed a…

One reason climates won't simply shift is that the length of daytime and the changes in that during the year will stay the same.

Sweden will still be very dark during winter and those Mediterranean plants won't necessarily be able to deal with that.

It's already happening but to get a new crop cultivar to market, like a new wheat or a new apple, takes >20 years. Several aspects re climate change will neccessitate making plants grow better (nutritious, pest resistant etc) despite the high CO2 - CO2 was only beneficial to humans when it was below 300ppm.

The article admitted that there has been a worldwide greening effect from increased co2 levels. The vast majority of plants grow bigger and faster when co2 is between 600 and 1500 ppm.

Above 600 increasingly toxic to us us, and above 300 mineral and protein falls off for most plants. Some plants also become > flammable. Have peer papers if interested.

China? They are having the worst floods and rains in a 1.000 year. I think the jury is still out there if they are going to be one of the worst affected by climate change.

It IS cold compared to the last 20 years AND to other regions in Europe. Can you please stop spreading lies with "it is not cold". Get your facts straight before you post anecdotes that your plants are growing "like hell".

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.
