Reduce tundra around what used to be the arctic, increase desert around
the equator. Not a large net change in amount of arable land. As usual
you are asserting that all change is bad without actually dealing with
the fact that change happens anyways. A shift in the location or arable
land is only bad to the folks near the edges of the growing deserts.
It's a good thing for folks at the northern edge who see their climates
improve.

This is the nonsense part. We still haven't reached the warmth of when
the Norse colonized cattle ranches on Greenland but it's irreversible.
And humans have caused increased volcanic activity. That would be a no.
Global warming as absolutely happened. There is some percentage of
human input. There is also a lot of nonsense by both the insisters and
the deniers.

So they are moving. Correct. You still aren't getting the point. What
is lost to deserts near the equator is gaining from the tundra near the
poles. A large change in location that is not a large change in the
total.

Folks still aren't addressing why change is automatically bad. So far
the reactions I've gotten are that yes change is in fact bad. I've read
enough history to know otherwise. Climate change brings large changes
in civilization which across time have been improvements. We live in
interesting times. Shrug, so it has always been.
