If you've seen any of the "Ice Age" animated Disney movies, we have some bad news: You don't know the real ice age. For the first time since 1972, NASA is putting science experiments on the moon in ...

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 ...

The Earth’s climate is a dynamic entity, continuously evolving over billions of years with alternating periods of extreme heat and cold. Recent scientific studies indicate that the Earth is subtly ...

Scientists have determined exactly how Earth's orbit and tilt affect glaciation and deglaciation, based on the length of these parameters' cycles and clues hidden at the bottom of the ocean. When you ...
