HUMAN-INDUCED climate change is driving the world to the brink of five “disastrous” tipping points, warns a major study published today.

Some of the critical thresholds that, when crossed, lead to large and often irreversible changes in the climate system, may have already been passed due to 1.1°C of global heating since the Industrial Revolution, researchers said.

These could include the collapse of Greenland’s ice cap and a key current in the north Atlantic, the disruption of rain patterns upon which billions of people depend for food and an abrupt melting of carbon-rich permafrost.
