   The earthworms in North America are invaders. There used to be native earthworms, but they were wiped out by glaciers around 10,000 years ago and all the current worms arrived accidentally (via humans) from Europe and Asia in the past few centuries.

   And now global warming is causing “global worming”, as worms spread northwards into a warmer Arctic:

   The consequences aren’t clear yet. But it’s a lot of change.
