Climate change: ‘Hothouse Earth’ risks even if CO2 emissions slashed

It may sound like the title of a low budget sci-fi movie, but for planetary scientists, “Hothouse Earth” is a deadly serious concept.

A study published in Proceedings of the National Academy of Sciences shows that there is a risk of Earth entering “Hothouse Earth” conditions where the climate in the long term will stabilize at a global average of 4-5°C higher than pre-industrial temperatures and sea level 10-60 m higher than today.

Researchers believe we could soon cross a threshold leading to boiling hot temperatures and towering seas in the centuries to come.

Even if countries succeed in meeting their CO2 targets, we could still lurch on to this “irreversible pathway”.
