What "climate change" will do in the future is speculation.

Remember the scientists telling us the BP oil spill would damage the ecosystem for generations?
What happened? The oil was consumed by microorganisms which in turn fed other things which in turn fed the fish which are more plentiful now then before.
Again we don't know enough to presume we know how this will all play out.
Don't get me wrong. I recycle and try to do my part, but unless you wipe out mankind from the earth. You yourself won't do diddly squat to change anything. China opens on average 35 new coal fires power plants every day!
