NASA scientists have uncovered significant changes in the global water cycle over the past two decades, largely driven by ...

First of all the rotation axis changes relative to the Earth’s surface which is referred to as polar motion. The main component of polar motion is the so-called Chandler wobble. Although it was ...

The wobble isn't new – it was first reported in 1728. But how this movement affects the moon's gravitational pull, the main ...

As climate change worsens and extreme weather events become the norm of the day, a new study led by American space agency, Nasa, confirms that Earth's water cycle is shifting in unprecedented ways.

"If we want to predict the effects of climate change on Earth's water resources, we need data showing how the hydrologic cycle will respond at a small scale where we can define mechanisms ...

Paleoclimate and archaeological evidence tells us that, 11,000-5,000 years ago, the Earth's slow orbital 'wobble' transformed today's Sahara desert to a land covered with vegetation and lakes.
