Earth observations show Europe’s natural wealth in steep decline

05 May 2018

In March 2018, French scientists reported a steep decline in the country's bird populations, primarily as a result of agricultural activity. Causes include the increase in monoculture, detrimental land-use policies and, perhaps most importantly, the growth in the use of powerful pesticides such as neonicotinoids, which, by killing off insects, reduces the bird population by reducing the food available to them.

Sentinels bring new outlook to Tibet glaciers

26 April 2018

On 17 July and 21 September 2016, two unprecedented giant ice avalanches of 70 or 80 million m3, respectively, rushed down from two adjacent glaciers in Tibet with speeds of up to 300 km/h, over slopes as low as a few degrees.

Before the Flood Arrives

24 April 2018

New NASA Study may improve future river-observing satellites.

River floods are one of the most common and devastating of Earth's natural disasters. In the past decade, deluges from rivers have killed thousands of people every year around the world and caused losses on the order of tens of billions of U.S. dollars annually. Climate change, which is projected to increase precipitation in certain areas of the planet, might make river floods in these places more frequent and severe in the coming decades.

Satellite imagery sheds light on agricultural water use

21 April 2018

Earth may be the "Blue Planet", with more than 70 percent of its surface covered in water, but it is still a thirsty planet, with freshwater in heavy demand. The most significant draw on the water supply is crop irrigation, accounting by some measures for nearly two-thirds of U.S. surface-freshwater withdrawals.

European State of the Climate report 2017

20 April 2018

The information provided by the Copernicus Climate Change Service (C3S) and the Copernicus Atmosphere Monitoring Service (CAMS) was used to develop the European State of the Climate 2017 report, an important step forward towards a better understanding and assessment of the state and the indicators of our changing climate.

NASA mapping hurricane damage to Everglades, Puerto Rico forests

13 April 2018

Last spring, NASA researchers flew over the Everglades and Puerto Rico to measure how mangroves and rainforests grow and evolve over time. Five months later, hurricanes Irma and Maria tore through those study areas – creating a unique opportunity to investigate the devastating effects of massive storms on these ecosystems, as well as their gradual recovery.

NRL meteorologist presents new wildfire climate research to global scientists

12 April 2018

Last year was a record year for wildfires across the globe, and their impact on the atmosphere remains highly uncertain. Thanks to new research from expert scientists at the U.S. Naval Research Laboratory, the world is gaining more insight into what drives these massive and escalating events.

Antarctica loses grip

03 April 2018

ESA's CryoSat mission has revealed that, over the last seven years, Antarctica has lost an area of underwater ice the size of Greater London. This is because warm ocean water beneath the continent's floating margins is eating away at the ice attached to the seabed.

Arctic wintertime sea ice extent is among lowest on record

23 March 2018

Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.

Sentinels helping to map minerals

20 March 2018

The traditional way of mapping Earth's geology and mineral resources is a costly and time-consuming undertaking. While satellites cannot entirely replace the expert in the field, they can certainly help – as a recent effort in Africa shows.
