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.

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 ...

Until now, the slow weathering of silicate rocks has been considered as the main factor in climate regulation. In this system, rain takes up carbon dioxide (CO 2) from the atmosphere, falls on exposed ...

The planet that appears so steady beneath our feet is, in reality, subtly reorienting itself in space. As ice melts, oceans ...

They don't cause ice ages, but they do control the volume of things like glaciation and the factors that can trigger ice ages. Kane's simulations show that without Mars the frequent and intense ...

Compared with Earth, Mars is tiny, yet it seems to have an outsized effect on our planet’s climate cycles. Similar small planets could affect the climates of worlds beyond our solar system, which we ...

Computer simulation of Earth's climate evolving over one million years in response to a sudden release of carbon dioxide to the atmosphere. UC Riverside researchers have discovered a piece that was ...
