The air we breathe

16 May 2019

Air pollution is a global environmental health problem, especially for those living in urban areas. Not only does it negatively impact our ecosystems, it considerably affects our health. According to the World Health Organization (WHO), around 8 million premature deaths per year are linked to air pollution, more than double of previous estimates.

World Space Alliance kicks off

16 May 2019

While scientists and data users continue to discuss the latest findings about our changing world and the space technologies that are needed to learn more, this week's Living Planet Symposium has also been the forum to forge and strengthen alliances. And, today sees the start of a two-year pilot for the ESA–SAP World Space Alliance.

New Zealand’s South Island imaged by Proba-V

15 May 2019

The snow-capped peaks of the Southern Alps stretch more than 500 km northeast to southwest across New Zealand's South Island, imaged here in the southern hemisphere's autumn by ESA's Proba-V minisatellite – now into its seventh year in orbit.

Ice coverage - the global thaw

15 May 2019

One of the causalities of climate change is the diminishing ice cover, affecting our planet in a number of ways. ESA's satellites observe the planet's cryosphere and provide key information to understand and respond to global thawing.

3D Earth in the making

15 May 2019

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 May 2019

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.

Tug-of-war drives magnetic north sprint

15 May 2019

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.
