Can oceans turn the tide on the climate crisis?

8.10.2019 14:37  

As we pump more greenhouse gases into the atmosphere, the world is warming at an alarming rate, with devastating consequences. While our vast oceans are helping to take the heat out of climate change, new research shows that they are absorbing a lot more atmospheric carbon dioxide than previously thought – but these positives may be outweighed by the downsides.

16.9.2019 14:50  

Researchers all over the world have a wealth of satellite data at their fingertips to understand global change, but turning a multitude of different data into actual information can pose a challenge.

Tracing the environmental impacts of supply chains

11.9.2019 15:15  

Globalisation and international trade allow us to consume produce from all over the world. But this comes at a cost to the environment – but, for the first time, satellite data combined with artificial intelligence is being usedtoprovide information to assess the impact of global supply chains.

Using machine learning for rewilding

10.9.2019 18:25

CryoSat conquers ice on Arctic lakes

5.8.2019 11:40  

The rapidly changing climate in the Arctic is not only linked to melting glaciers and declining sea ice, but also to thinning ice on lakes. The presence of lake ice can be easily monitored by imaging sensors and standard satellite observations, but now adding to its list of achievements, CryoSat can be used to measure the thickness of lake ice – another indicator of climate change.

Washed up: Sargassum blankets beaches

Second laser boosts Aeolus power

23.7.2019 14:40  

ESA’s Aeolus satellite, which carries the world’s first space Doppler wind lidar, has been delivering high-quality global measurements of Earth’s wind since it was launched almost a year ago. However, part of the instrument, the laser transmitter, has been slowly losing energy. As a result, ESA decided to switch over to the instrument’s second laser – and the mission is now back on top form.

3D Earth in the making

15.5.2019 15:00  

A thorough understanding of the ‘solid Earth’ system is essential for deciphering the links between processes occurring deep inside Earth and those occurring nearer the surface that lead to seismic activity such as earthquakes and volcanic eruptions, the rise of mountains and the location of underground natural resources. Thanks to gravity and magnetic data from satellites along with seismology, scientists are on the way to modelling inner Earth in 3D.

Water cycle wrapped

15.5.2019 12:00  

As our climate changes, the availability of freshwater is a growing issue for many people around the world. Understanding the water cycle and how the climate and human usage is causing shifts in natural cycling processes is vital to safeguarding supplies. While numerous satellites measure individual components of the water cycle, it has never been described as a whole over a particular region – until now.

Tug-of-war drives magnetic north sprint

15.5.2019 9:55  

As far as we know, Earth’s magnetic north has always wandered, but it has recently gained new momentum and is making a dash towards Siberia at a pace not seen before. While this has some practical implications, scientists believe that this sprint is being caused by tussling magnetic blobs deep below our feet.

Mapping salty waters

14.5.2019 15:45  

The length and precision with which climate scientists can track the salinity, or saltiness, of the oceans is set to improve dramatically according to researchers working as part of ESA’s Climate Change Initiative.
