Earth Minute Videos

This fun-filled, yet sobering, whiteboard animation series explains Earth science to the science-curious. Earth is a complex, dynamic system we do not fully understand. To learn more about it, NASA, as the agency with access to space, was tasked with launching the first weather satellite back in 1960. Today, NASA uses satellites, aircraft and even an occasional boat to study our planet's air, land and water. It's called "Earth system science" and we are trying to answer some big questions: How is the global Earth system changing?

Aerosols are minute solid and liquid particles suspended in the atmosphere. Clouds are complicated when it comes to climate science, as they both warm and cool Earth. Located in the Arctic near the North Pole, the island of Greenland is covered by a massive ice sheet three times the size of Texas and a mile deep on average.

Will Photo of Drowned Syrian Boy Be a Turning Point?

"I happen to be a photographer multiple levels after just being a human," says Stanmeyer, a National Geographic contributor who has been covering the Syrian refugee crisis and who has covered humanitarian disasters for decades. "I see myself there. I see my own children there. " But Stanmeyer says the world needs to see images of the refugee crisis, which shows no sign of abating. An estimated 13.9 million people were displaced last year due to conflict such as the war in Syria, persecution and poverty, according to the United Nations.

10 Resources for Teaching and Learning About Weather

I'm sure the rain put a damper on a few picnics today. It certainly caused a change in my plans for the day. But at least the rain inspired me to look back at some of the many resources for teaching and learning about weather that I have reviewed over the years. Here are ten resources for teaching and learning about weather. Road-Eating, Slow-Motion Landslide Caught on Video. Like watching a slow-motion disaster, a video that's going viral this week shows a dramatic landslide in eastern Russia gradually swallowing up a road and railway, knocking down trees and power lines, and dragging heavy equipment.

No one was hurt in the creeping landslide, or earthflow, coal industry representative Larissa Beresneva told local Russian media. The disaster happened on April 1 near Novokuznetsk, east of the Ural Mountains. (Learn more about the impacts of coal.) The region is an active coal mining area and the massive slide seems to have occurred as a result of a collapse of the waste material, or overburden, from the Taldinskoye coal mine, Beresneva said. Overpopulation, overconsumption – in pictures.

Sää kampittaa meteorologit. Aral-järvi. Once the fourth largest lake in the world, Central Asia's shrinking Aral Sea has reached a new low, thanks to decades-old water diversions for irrigation and a more recent drought.


Satellite imagery released this week by NASA shows that the eastern basin of the freshwater body is now completely dry. "It is likely the first time it has completely dried in 600 years, since medieval desiccation associated with diversion of Amu Darya [river] to the Caspian Sea," Philip Micklin, an Aral Sea expert and a geographer emeritus from Western Michigan University, in Kalamazoo, told NASA about the sea's eastern basin.

(See "Photos: Dried Up Aral Sea Aftermath. ") An image made by NASA's Terra satellite in August and released on Tuesday shows the sea without its eastern lobe, a noticeable difference from an image made on August 25, 2000. Actually a freshwater lake, the Aral Sea once had a surface area of 26,000 square miles (67,300 square kilometers). Tectonic Settings and Volcanic Activity.
