A battle for the jet stream is raging above our heads

When prolonged periods of severe weather strike, two things often get the blame these days: climate change and the jet stream. Many have expressed concerns that the rapidly melting Arctic is now disturbing the jet stream, ...

How frigid polar vortex blasts are connected to global warming

A record-breaking cold wave is sending literal shivers down the spines of millions of Americans. Temperatures across the upper Midwest are forecast to fall an astonishing 50 degrees Fahrenheit (28 degrees Celsius) below normal ...

Finding the pulse of the polar vortex

If you can predict the path of the jet stream, the upper atmosphere's undulating river of wind, then you can predict weather – not just for a week or two, but for an entire season. A new Stanford study moves toward that ...

World sees rapid upsurge in extreme weather: report

A world addled by climate change has seen a four-fold increase in major flooding events since 1980, and a doubling of significant storms, droughts and heat waves, Europe's national science academies jointly reported Wednesday.

NASA satellite sees a warm winter in the Western US

While people in the eastern two-thirds of the U.S have been dealing with Arctic Air, the bulge in the Jet Stream over the eastern Pacific Ocean has been keeping the western third of the U.S. in warmer than normal temperatures ...

NASA image: Saturn's vortex and rings

The Cassini spacecraft captures three magnificent sights at once: Saturn's north polar vortex and hexagon along with its expansive rings.
