Earth has experienced several climate cycles throughout its long history, including several ice ages that caused the planet to freeze over. The last ice age occurred approximately 11,700 years ago, ...

Climate change deniers inaccurately claim that Earth's rapidly rising temperatures are the mere product of natural cycles. Scientific experts have long explained that, although Earth does experience ...

Scientists say they have found geochemical traces of Earth’s ancient self hidden far below our feet, suggesting that parts of the planet that existed before the Moon-forming collision 4.5 billion ...

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests ...

This doesn’t mean Mars causes ice ages on its own. Orbital cycles are only part of the picture. Earth’s oceans, atmosphere, ...

Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

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.

"Such a transition to a glacial state in 10,000 years' time is very unlikely to happen, because human emissions of carbon dioxide into the atmosphere have already diverted the climate from its natural ...
