What does the latest science say about the climate crisis?

Planet Earth truly is in uncharted territory, says Johan Rockström, director of the Potsdam Institute for Climate Impact Research. The world is the hottest it has been for at least 100,000 years - and not only is the rate of warming higher than at any time in recorded history, that rate is also accelerating. Appearing on the World Economic Forum podcast Radio Davos, Rockström gives the latest take on what the climate science is saying: how a drop in the planet’s resilience is drawing us ever closer to irreversible tipping points, from the mass collapse of coral reefs to permafrost melt, and how breaching a 1.5°C rise in global temperature is now ‘unavoidable’ - at least temporarily.
