Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

Nunalleq, a village in what’s today southwest Alaska, seemed to have thrived during the Little Ice Age. How did this village manage to survive and prosper during this time period? And what caused this period of climate change in the...

The climate of the Sahara was completely different thousands of years ago. And we’re not talking about just a few years of extra rain. We’re talking about a climate that was so wet for so long that animals and humans alike made...

Africa’s Sahara desert is a prime location, some say, to build arrays of solar panels and wind turbines. But scientists are aware that building these structures can potentially have large-scale effects on the surrounding environment that...

In this science project, you will explore Urban Heat Islands with ArcGIS Online and analyze surface type & air temperature relationships in your city.

Climate is the average type of weather that a region has. It is defined by temperature and moisture. Proximity to oceans and large mountain ranges defines climate too, depending upon the prevailing wind. While climates change over...

Hot super-Earths are fiery rocky planets orbiting so close to their suns that their surface is heated to lava oceans. <br/>

NASA Goddard Space Flight Center scientist Andrew Sayer talks about how emissions from volcanoes can affect clouds. This video provides an overview of research published in the Journal of Atmospheric Chemistry and Physics. Research:...

Arctic sea ice likely reached its 2019 minimum extent of 1.60 million square miles (4.15 million square kilometers) on Sept. 18, tied for second lowest summertime extent in the satellite...

A look at how the historic DaisyWorld model illustrates earth science concepts, such as albedo and feedback loops. This webshort was produced as an educational tie-in with the Science on a Sphere feature LOOP.

A number of people who've seen NASA's annual lunar phase and libration videos have asked what the other side of the Moon looks like, the side that can't be seen from the Earth. This video answers that question. The imagery was created...

This 4K visualization shows the Moon's phase and libration at hourly intervals throughout 2021, as viewed from the Southern Hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon's orbit...
