To be clear, I think we should reduce emissions. But even if they drop to zero today, we still have a problem. Trees and Algae don't use more carbon than the used to. The carbon cycle is fairly neutral in terms of the net change year over year, absent us.

My point in commenting was to say that climate change is not irrelevant, and emphasize that using less is helpful, but won't solve the problem on its own.
