Today I learned that Forests migrate

Forests migrate way slower than climate changes... every past ice age and warm period we lost hundreds of species that could not move along fast enough with their climate niche,....

With the accelerated climate change in the Anthropocene we risk loosing almost all of our species unless we migrate them ourselves (animals are usually less susceptible but they need their ecological umbrella ecosystem to move to a new area first, in order to keep them when rushing a move in skips we will have to move them ourselves too)...

Trust me, the still outstanding climate change is scary and makes CoViD19 look like a fire drill for toddlers.

Plus side: If we manage to wing climate change we will have gotten some first hands on experience in terraforming.
Minus side: If we mess it up we could effectivley pass the sceptre of "most intelligent life form on the planet" to the ants or bees or whatever state building insects will survive the ecological shipwreck.

Interesting side note concerning species adaptation and geography. Some of the worst mass extinctions have occurred when the continents were not aligned North-South. There was no way for animals to migrate to upper or lower latitudes as the climate changed. (Mind you, this hasn't been a factor in all extinction events, just in some.)

With the current configuration of North-South aligning continents, species could march up and down in tandem with rising or falling temperatures. But within the last few hundred years, humans have effectively chopped up the continents with roads, damns, and cities. We're impeding the migration of species, at the same time that we've spurred rapid climate change, so we're making it doubly hard for plants and animals to adapt.

Humans. The horror story never ends.

This is a well known and well studied phenomena. The article was a nice overview of this student's work, but the student's advisor (or the authors) was a bit remiss in not putting some context on the work. It is a bit ironic given the publisher's UK origins. The foundation of forest movement was formalized by Clement Reid who noted the difference in the rates that oak forests spread as glaciers receded from the British Islands and the theoretical rates of spread during the Pleistocene period. That difference would later be called Reid's Paradox.

The oak, to gain its present most northerly position in North Britain after being driven out by the cold probably had to travel fully six hundred miles, and this without external aid would take something like a million years. (Reid 1899)
Later studies would confirm that oak forests were moving at a rate of up to hundreds of meters per year. Reid concluded that birds, most likely jays, were the primary seed dispersal mechanism. Up till then it was assumed rodents were the main dispersal agent. His work was repeated in other areas, and this continues to be an active area of research for mathematical ecologists.
