Wind holds key to climate change turnaround

Antarctica has a current that circles the landmass as part of the Southern Ocean. This current is called the Antarctic Circumpolar Current. When the westerly winds strengthen during the Southern Hemisphere's summer, waters ...

Stronger west winds blow ill wind for climate change

Stronger westerly winds in the Southern Ocean could be the cause of a sudden rise in atmospheric CO2 and temperatures in a period of less than 100 years about 16,000 years ago, according to a study published in Nature Communications.

Leaky atmosphere linked to lightweight planet

The Red Planet's low gravity and lack of magnetic field makes its outermost atmosphere an easy target to be swept away by the solar wind, but new evidence from ESA's Mars Express spacecraft shows that the Sun's radiation ...

The moving Martian bow shock

As the energetic particles of the solar wind speed across interplanetary space, their motion is modified by objects in their path. A study, based on data from ESA's Mars Express orbiter, has thrown new light on a surprising ...

MAVEN's top 10 discoveries at Mars

On June 17, NASA's MAVEN (Mars Atmosphere and Volatile Evolution Mission) will celebrate 1,000 Earth days in orbit around the Red Planet. Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN ...

Understanding changes in extreme precipitation

Most climate scientists agree that heavy rainfall will become even more extreme and frequent in a warmer climate. This is because warm air can hold more moisture than cold air, resulting in heavier rainfall.
