How melting Arctic ice could cause uncontrollable climate change

Arctic scientists have warned that the increasingly rapid melting of the ice cap risks triggering 19 "tipping points" in the region that could have catastrophic consequences around the globe.

The Arctic Resilience Report found that the effects of Arctic warming could be felt as far away as the Indian Ocean, in a stark warning that changes in the region could cause uncontrollable climate change at a global level.

Temperatures in the Arctic are currently about 20C above what would be expected for the time of year, which scientists describe as "off the charts". Sea ice is at the lowest extent ever recorded for the time of year.

"The warning signals are getting louder," said Marcus Carson of the Stockholm Environment Institute and one of the lead authors of the report. "These developments also make the potential for triggering tipping points and feedback loops much larger."
