Scientists have predicted future glacial periods by matching Earth's past ice ages to its orbit around the sun. One thing their model doesn’t account for: How human ...

First, what is an ice age? It’s when the Earth has cold temperatures for a long time – millions to tens of millions of years – that lead to ice sheets and glaciers covering large areas of its surface.

Earth has long alternated between ice ages and warmer interglacial periods The Earth's next ice age is expected to begin in about 11,000 years -- unless human-caused global warming disrupts natural ...

A new study suggests that Earth’s next ice age should begin within the next 11,000 years - except our impact on the planet may delay it, potentially by thousands of years. Scientists have long known ...

Most people know the theory that an asteroid wiped out the dinosaurs 66 million years ago. But Earth has faced at least five mass extinctions, and not all were caused by space rocks. Scientists now ...
