Humans are changing the climate in profound ways, triggering rapid changes and increasing extreme events around the world, a much anticipated climate report released this morning warns. Some of these changes, particularly involving the oceans and polar regions, will be irreversible for millennia.
The climate assessments released by the Intergovernmental Panel on Climate Change are a big deal. They’re the guidebooks many governments use as they plan their climate policies. The new report lays out climate changes so far and what’s ahead if greenhouse gas emissions continue at a high rate. Robert Kopp, a lead author of the chapter on ice and oceans, explains the findings and what they say about tipping points, sea level rise and the future.
