But due to human carbon emissions, the lethal 'big freeze' could be put off.
Levels of CO2 in the atmosphere could actually insulate against a catastrophic ice age which would see glaciers advance over Europe and north America.
The scientists admit that we would be 'better off' in a warmer world - but caution that this is 'missing the point'.
In a paper published in Nature Geoscience, Cambridge University paleoclimatologist Luke Skinner says that even if carbon emissions stopped today, levels would remain elevated for at least 1,000 years, and stored heat could prevent the next Ice Age from happening.
Instead, things would cool down, but not quite so severely.
