A new study shows that during the last two deglaciations, i.e., the transition from an ice age to the warm interglacial periods, meltwater from the Antarctic ice sheet intensified stratification in ...

Using satellite data and the physics of ice flow, researchers have mapped Antarctica’s hidden subglacial bedrock landscape – one of the Solar System’s least mapped planetary surfaces – in ...

Earth’s path around the Sun is not a fixed racetrack but a slowly shifting orbit, and those subtle changes have a long history of reshaping the planet’s climate. As astronomers refine how these ...

Today’s maps lie — because for most of human history, the world looked nothing like this. During the last Ice Age, ice sheets buried continents, oceans shrank, and land bridges formed where seas now ...
