This has been on my mind this past week(and is only lightly tangential)...but would we be able to observe adaptations being made by plants/animals/ecosystems on a timescale of years or decades...to the changing climate?

Humans will be playing mental gymnastics and politics for quite a while before any true changes to move the needle are made...but all other biological things can just make the adaptations...given enough cycles to recognize that something is different(the last 3 seasons were much wetter or colder or hotter, etc...).

I imagine these adaptations could be earlier/later migrations, reproduction habits, hibernation patterns, food gathering. Not necessarily changes in DNA.
