A runaway greenhouse Armageddon in which the oceans boil dry could theoretically happen on Earth, researchers claim.
The good news is that human activity on its own will probably not be enough to trigger such an end-of-the-world scenario in the near future.
Previously it was thought more energy from the sun would be needed for global warming on Earth truly to spin out of control.
But new calculations from Canadian and US scientists show that catastrophic warming can occur more easily than had been assumed.
For a planet receiving the same amount of solar radiation as the Earth, a runaway greenhouse effect is a realistic possibility.
The team, led by Colin Goldblatt from the University of Victoria in Canada, wrote in the journal Nature Geoscience: “The runaway greenhouse may be much easier to initiate than previously thought.
