Scientists have determined exactly how Earth's orbit and tilt affect glaciation and deglaciation, based on the length of ...

Scientists say small changes in the way the Earth orbits the sun hold the key in major global changes in climate, like ice ...

Earth emerged from the last ice age around 11,700 years ago. A new analysis suggests the next one could be expected in 10,000 ...

Changes to the seasons will also have big impacts on the environment—altering the growing seasons for plants and changing ...

Earth’s climate follows a natural cycle of ice ages and warm periods. A new study shows that small orbital changes drive ...

Coauthor of the study, Professor Lorraine Lisiecki of the University of California, Santa Barbara, added: “This is important ...

Giant glaciers scraped parts of the Earth's crust, releasing key minerals into the ocean millions of years ago, a study ...

It has been assumed that changes in the Earth's orbit around the sun are responsible for the ice age cycles. It is now clear ...

The Earth's next ice age is expected to begin in about 11,000 years -- unless human-caused global warming disrupts natural ...

Climate change has likely contributed to the unprecedented ... The sun may be the key to all life on Earth, but it is not the reason global temperatures have been rapidly rising in the last ...

As Earth approaches warmer levels experienced earlier in its geologic history, it may be bad news for human survival.

Birds adjust survival strategies based on climate. Some breed quickly, while others live long and delay reproduction.
