Slow flow for glaciers thinning in Asia

Mon, 10/12/2018 - 16:15

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.

Learning from lunar lights

Fri, 07/12/2018 - 13:31

Every few hours observing the Moon, ESA’s ‘NELIOTA’ project discovers a brilliant flash of light across its surface – the result of an object hurtling through space and striking our unprotected rocky neighbour at vast speed. Based at the Kryoneri telescope of the National Observatory of Athens, this important project is now being extended to January 2021.

Another El Niño on the horizon?

Fri, 07/12/2018 - 10:00

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.
