Why is my weather app sometimes wrong? Well it has a lot to do with wind. Jet Streams, air cells, the shape and movement of the Earth... there are a lot of things that make weather a little unpredictable. In this episode of Crash Course...

As the whales swim south, the water gets colder and more dangerous, with predators like sharks and killer whales nearby. Baby humpbacks stay quiet, using soft sounds to talk to their moms and avoid being found. Ocean currents like the...

This video delves into the significant impact of oceans on global climate. It explains how oceans, covering 70% of the Earth's surface, absorb and redistribute solar energy, influencing weather patterns and climate zones. The process...

In this video Paul Andersen describes both weather and climate. Weather is the day-to-day conditions on the Earth's surface, including temperature, wind, humidity, air pressure, and precipitation. Climate are the long term conditions...

You'd think that the Northern and Southern Hemispheres would be basically symmetrical -- that since our planet is a ball, the climate, temperature, and weather patterns would be the same on top as on the bottom. But there are some...

Warming ocean water is weakening a major current system called the Atlantic Meridional Overturning Circulation (AMOC), which helps regulate global weather. Melting ice in Greenland and freshwater from rivers are making the ocean less...

The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet...

This is the science of what, where, and how of rip currents. Most lifeguard rescues on ocean beaches in the United States are for rip currents. See how to avoid rip currents and learn safety from these killer currents on beaches. They...

This video highlights the collaborative efforts between NASA and the Office of Naval Research to study ocean waves and their impact on our atmosphere. Through field studies and laboratory research, scientists are gaining a better...

This video explores the international effort between NASA and the Office of Naval Research to study ocean waves off the coast of Virginia. By using aircraft, ships, and buoys, they aim to better understand how waves develop and...

Water on Earth focuses on water as most kids would think about it. We start with water in obvious locations such as oceans, lakes, and rivers. We quickly learn that water can change phase to remain a solid in glaciers. Many kids may be...

Ocean waters are constantly on the move, traveling far distances in complex currents that regulate Earth's climate and weather patterns. How might climate change impact this critical system? Oceanographer Susan Lozier dives into the...

On Sept. 9th, 2011, Arctic sea ice most likely hit its minimum extent for the year. On Sept. 20th, NASA's Cryosphere Program Manager, Tom Wagner, shared his perspectives on the ice with television audiences across the...

After traveling thousands of miles, the young humpback whale reaches Antarctica, where the cold waters are full of food like Antarctic krill. Whales use a smart hunting method called bubble netting—blowing bubbles to trap krill so they...

Bayes Theorem and some of the mysteries it has solved

Climate change is one of the most important issues facing our planet, and NASA has lots of space missions and programs in the works to monitor and understand its drivers and effects. Kate Calvin, NASA’s new chief scientist, is also the...

The legendary El Niño effect causes dramatic shifts of weather, resulting in droughts and floods across the globe. It can all be traced to winds dying down over the Pacific ocean. Earth Science - Weather - Learning Points. El Niño is a...

National Geographic explorer and University of Tokyo behavioral ecologist Katsufumi Sato outfits oceangoing birds with weather data recorders, a technique that could improve the accuracy of forecasts. ➡
