Years of Living Dangerously - Season 1

Climate change is one of today's most hotly debated topics, not only in America but around the world. This series features firsthand accounts from people who have been affected by the occurrence, with a team of correspondents from the entertainment and news industries traveling around the world to report on effects of global warming and what people are doing to find solutions for it. Among the stories told are Oscar-winner Matt Damon's reporting on the health impact of heat waves around the globe, Golden Globe-winner Michael C.

OMG - Oceans Melting Greenland mission by NASA

From NASA OMG Mission website -- Global sea level rise will be one of the major environmental challenges of the 21st Century. Oceans Melting Greenland (OMG) will pave the way for improved estimates of sea level rise by addressing the question: To what extent are the oceans melting Greenland’s ice from below? Over a five-year campaign, OMG will observe changing water temperatures on the continental shelf surrounding Greenland, and how marine glaciers react to the presence of warm, salty Atlantic Water.

NASA - Why Do Raindrop Sizes Matter In Storms?

Not all raindrops are created equal. The size of falling raindrops depends on several factors, including where the cloud producing the drops is located on the globe and where the drops originate in the cloud. For the first time, scientists have three-dimensional snapshots of raindrops and snowflakes around the world from space, thanks to the joint NASA and Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) mission.

NASA's Earth Minute series on global climate change

Did you know NASA has studied Earth more than any other planet in our solar system? It's one of NASA's most important missions and its unique capabilities in space give us a global view of our changing planet. Subscribe in YouTube to this bi-weekly animated series as NASA looks at earth science topics and explains why climate change is a big deal in 90 seconds or less.

Dwindling of Arctic's oldest ice since 1990

From NOAA Climate  --  Time lapse of the age of sea ice in the Arctic from week to week since 1990, updated through the March 2016 winter maximum. The oldest ice (9 or more years old) is white. Seasonal ice is darkest blue. Old ice drifts out of the Arctic through the Fram Strait (east of Greenland), but in recent years, it has also been melting as it drifts into the southernmost waters of the Beaufort Sea (north of western Canada and Alaska).

NASA | A Week in the Life of Rain

Rain, snow, hail, ice, and every slushy mix in between make up the precipitation that touches everyone on our planet. But not all places rain equally. Precipitation falls differently in different parts of the world, as you see in NASA's new video that captures every shower, every snow storm and every hurricane from August 4 to August 14, 2014. The GPM Core Observatory, co-led by NASA and the Japan Aerospace Exploration Agency (JAXA), was launched on Feb 27, 2014, and provides advanced instruments that can see rain and falling snow all the way through the atmosphere.

El Niño and La Niña Explained

This video is from the NOAA Ocean Today collection. The video explains and shows the interaction between the trade winds, surface ocean movement, jet stream, and the climatic impacts. What this video shows that is not found in other videos is a map view and cross sectional view of the Pacific Ocean basin, demonstrating the trade winds blowing the warm water to the western Pacific at the same time the upwelling of the colder water is occurring in the eastern Pacific.
