Grow the crops somewhere else? The earth's climate has always changed - the sea was 100m lower 20k years ago and much of Europe covered by ice. But it doesn't change so much over one human lifetime.

20k years ago, humans hadn't invented agriculture. Our whole civilization has existed in one particular geological time, an exceptional one. There is absolutely no indication that it's flexible enough to be transposed in another, and particularly not at that speed of transition, which is, in geological time, exceptionally fast.

We've gotten this far because we've had a rather stable climate for the past few thousand years. The current rate of the change is the problem. You must have missed it: https://xkcd.com/1732/ https://xkcd.com/1732/

  It's still ~1C over a human lifetime which gives you a fair bit of time to adapt. I mean I may fly to Bali next month due to climate but that's just London being crap in winter as usual.

    This is like saying fish can survive around 21C so the lower temperature of 19.8C that is keeping it in a -4C freezer for 3.5 hours before searing it for 30 minutes at 200C is fine. A 1C rise means hotter hots, colder colds, stronger storms and longer or more frequent droughts as well as the general climate of a region possibly changing. Yes you can find crops that will grow in specific conditions, but you need to know those conditions and if you have a day that kills a crop that can mean you need to wait for the next season. That 1C rise corresponds with a lot more of these crop damaging events as well as changing the efficiency and possibly infrastructure needed in an area. I'll also note that the last 1C rise is over a generation not a lifetime i.e. 25 years not 80.

      Brandolini's law at its finest. Don't waste your time, you're answering to a troll.
