Study: When will a warming Earth copy the greenhouse effect of Venus?

This article discusses looking at what happened to Venus as a result of the Greenhouse effect. Modelling finds the precious equilibrium between temperature and radiation breaks down beyond a certain point, spelling big trouble.

Climate models show a warming Earth radiates more heat into space, but when pushed too far, and this release valve shuts down, temperatures skyrocket to potentially Venusian levels.

Anyone familiar with a cooker knows that the hotter it gets the more heat it radiates. So too with the Earth. Remarkably for such a complex system, however, the heat radiating from the planet is in linear relation with the temperature increase of its surface – a mysteriously simple arrangement known to scientists since the 1950s.

Now, climate models published in the journal Proceedings of the National Academy of Science, calculated by researchers at the Massachusetts Institute of Technology’s Department of Earth, Atmospheric and Planetary Sciences (EAPS), have revealed why this linear relation holds – and when it may break down to the detriment of all life.
