A MAJOR reason we need to accelerate action to halt greenhouse gas emissions is that we're nearing planetary tipping points like the ones described in this piece. Ice sheet and permafrost loss will translate into much larger climate change too.

3 massive changes you'll see as the climate careens toward tipping points
Scientists are increasingly concerned that the planet is headed for massive, irreversible changes due to global warming. In some cases, those changes have already begun.
