Blog - How Likely Is a Runaway Greenhouse Effect on Earth?
The results of the latest analysis are not entirely reassuring. Sometime in the last few billion years, disaster struck one of Earth's nearest neighbours. Planetary geologists think there is good evidence that Venus was the victim of a runaway greenhouse effect which turned the planet into the boiling hell we see today.

Early Ice Ages
New research led by scientists from Oxford University and Exeter University has shown that the invasion of the land by plants in the Ordovician Period (488-443 million years ago) cooled the climate and may have triggered a series of ice ages. During this period sea levels are very high and at the end of the period there was a mass extinction event. At the beginning of the period, around 480 ...
