Yes. But a warmer Earth will not spell doom for the environment
Some species may be doomed by the warming, but they are all species that are already on the brink. If this doesn't get them then something else will.
My argument is that a warmer Earth is a good thing. Evolution will take its course, and I will be on the golf course enjoying the warm Iowa weather in January.
Hopefully it will start getting warmer fast. I'm scheduled to retire in about 20 years or so.
