A peer-reviewed study published in Nature Geoscience has found that during Earth’s most extreme ancient warming periods, ...

Key climate tipping points may be closer than expected, raising the risk of accelerating warming, sea-level rise, and ...

The planet has always changed. Ice ages came and went, oceans rose and fell, climates shifted over geological timescales. That's the story we've told ourselves for comfort, and it's technically true.

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial tilt. These variations, known as Milankovitch cycles, ...

At half the size of Earth and one-tenth its mass, Mars is a featherweight as far as planets go. And yet, new research reveals the extent to which Mars is quietly tugging on Earth’s orbit and shaping ...

Even when Earth was locked in a global deep freeze, its climate may have kept moving. Ancient rocks reveal seasonal and decade scale cycles beneath the ice during Snowball Earth.

For 42 years, NASA satellites have tracked how sunlight powers Earth’s climate. The long record is revealing subtle shifts that could reshape climate predictions. These findings are adding new layers ...
