A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect — in both shape and in rotation. Earth is not a perfect sphere.

Earth’s spin is not as steady as it looks. As ice melts and groundwater is pumped from deep aquifers to the surface, the planet’s mass is shifting, and with it the position of the rotational axis that ...

Climate change is altering the Earth to its literal core, new research suggests. As polar and glacial ice melts because of global warming, water that was once concentrated at the top and the bottom of ...

Climate change is causing the ice masses in Greenland and Antarctica to melt. Water from the polar regions is flowing into the world’s oceans –and especially into the equatorial region. “This means ...

Aren’t the summer days supposed to be longer and the winter days shorter? Since when have things gone in reverse for the summertime? Since now, maybe? Starting today? Okay, here’s what’s going on.

Glacial melting due to global warming is likely the cause of a shift in the movement of the poles that occurred in the 1990s. The locations of the North and South poles aren’t static, unchanging spots ...

Hold onto your sense of balance. Scientists have found fresh proof that Earth doesn't just drift through space — sometimes, it actually tips over. You already know that continents slowly move due to ...

Earth wobbles on its axis like a spinning top, a motion called precession. This wobble takes about 26,000 years to complete one full circle. Different stars have served as the North Star throughout ...
