Slow flow for glaciers thinning in Asia

10 December 2018

Providing water for drinking, irrigation and power, glaciers in the world's highest mountains are a lifeline for more than a billion people. As climate change takes a grip and glaciers lose mass, one might think that, lubricated by more meltwater, they flow more quickly. However, satellite images from over the last 30 years show that it isn't as simple as that.

Another El Nino on the horizon?

07 December 2018

The jury is still out as to whether climate change will lead to stronger El Niño events, but while representatives from around 200 countries at the COP24 conference are working to breathe life into the 2105 Paris Agreement, there is a 75–80% chance that a fully-fledged event could be with us in the next couple of months.

Greenhouse Gas ‘Detergent’ Recycles Itself in Atmosphere: NASA Study

30 November 2018

A simple molecule in the atmosphere that acts as a "detergent" to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new NASA research. Understanding its role in the atmosphere is critical for determining the lifetime of methane, a powerful contributor to climate change.

Tackling drought issues for food security

29 November 2018

This summer's drought is a harsh reminder of how unusual weather can cause havoc for farmers – even in a rich part of the world like Western Europe. While there is a wealth of satellite data available to help predict the risk of drought, it can be daunting for a non-expert to handle. ESA's Food Security Thematic Exploitation Platform makes this task much easier.

International Team, NASA Make Unexpected Discovery Under Greenland Ice

14 November 2018

An international team of researchers, including a NASA glaciologist, has discovered a large meteorite impact crater hiding beneath more than a half-mile of ice in northwest Greenland. The crater — the first of any size found under the Greenland ice sheet — is one of the 25 largest impact craters on Earth, measuring roughly 1,000 feet deep and more than 19 miles in diameter, an area slightly larger than that inside Washington's Capital Beltway.

Ozone hole could've been a big one this year – but it wasn’t

02 November 2018

The ozone hole that forms over the Antarctic each September is primarily driven by two factors: the amount of ozone-destroying chlorine in the polar stratosphere and the availability of ice crystals in stratospheric clouds for the chlorine to bind to.
