Is global warming hiding underwater?

07 February 2014

Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of the climate system and, in particular, how the ocean stores heat.

New pan-European flood hazard map

06 February 2014

Several parts of Europe, notably Italy, France, Ireland and Great Britain, are currently facing floods following the heavy rains that started in December. In order to improve the management of such events, mapping is needed of where floods can occur under certain circumstances.

NASA study points to infrared-herring in apparent Amazon green-up

06 February 2014

For the past eight years, scientists have been working to make sense of why some satellite data seemed to show the Amazon rain forest "greening-up" during the region's dry season each year from June to October. The green-up indicated productive, thriving vegetation in spite of limited rainfall.

Arctic lakes show climate on thin ice

03 February 2014

Ice in northern Alaska's lakes during winter months is on the decline. Twenty years of satellite radar imagery show how changes in our climate are affecting high-latitude environments.

El Nino's impact on continental evaporation

22 January 2014

As global temperatures gradually increase, more water is expected to evaporate into the atmosphere. But using satellite data, scientists have discovered that El Nino-induced droughts have caused global declines in evapotranspiration despite rising temperatures.

NASA finds 2013 sustained long-term climate warming trend

21 January 2014

NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures.

Taking Earth's temperature

13 January 2014

Like thermometers in the sky, satellite instruments can measure the temperatures of Earth's surfaces. ESA's new GlobTemperature project is merging these data from a variety of spaceborne sensors to provide scientists with a one-stop shop for land, lake and ice temperature data.

DLR satellite data helps in the rescue of the Akademik Shokalskiy

09 January 2014

For ten days, 74 scientists and tourists were trapped in the Antarctic on board the Russian Akademik Shokalskiy research vessel. Strong winds had driven ice floes into a bay, blocking the ship's advancement. High-resolution satellite data provided by the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) helped to assess the ice conditions at the location.

What lies beneath?

09 January 2014

A field campaign dedicated to SMOS and GOCE has revealed unexpected similarities in the missions' very different types of measurements. This surprising discovery could lead to a better understanding of what is happening deep under the Antarctic ice sheet.

Enormous aquifer discovered under Greenland ice sheet

23 December 2013

A team of glaciologists serendipitously found the aquifer while drilling in southeast Greenland in 2011 to study snow accumulation. Two of their ice cores were dripping water when the scientists lifted them to the surface, despite air temperatures of minus 4 F (minus 20 C).

Scientists solve a decades-old mystery in the Earth's upper atmosphere

18 December 2013

New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe.

Long-term warming and environmental change trends persist in the Arctic in 2013

12 December 2013

According to a new report released today by NOAA and its partners, cooler temperatures in the summer of 2013 across the central Arctic Ocean, Greenland and northern Canada moderated the record sea ice loss and extensive melting that the surface of the Greenland ice sheet experienced last year. Yet there continued to be regional extremes, including record low May snow cover in Eurasia and record high summer temperatures in Alaska.

HALO flies to the Caribbean - Cloud research for better climate models

10 December 2013

Clouds can both warm and cool Earth's atmosphere. In current climate models, detailed conditions for cloud cover as a climatic factor are still not clearly understood. There is a shortage of precise measurements on how the water, humidity, ice particles and aerosols that form water droplets are distributed in towering cumulus clouds.

Antarctica's ice loss on the rise

09 December 2013

Three years of observations by ESA's CryoSat satellite show that the West Antarctic Ice Sheet is losing over 150 cubic kilometres of ice each year - considerably more than when last surveyed.
