The Paris agreement, even if it were implemented faithfully, was still woefully inadequate. Not only that, but the longer we wait, the more severe cuts will be necessary.

Because of these considerations and our previous track record, I just really don't see the world cooperating on this issue well enough to meaningfully cut emissions. Eventually, renewables will become much cheaper than fossil fuels. At that point, emissions will hugely drop just due to market forces. We'll already be locked into some pretty bad outcomes by then though.
