Weather stations can be used to calibrate and validate albedo measurements from satellites, but they fail to account for variability across landscapes, overestimating how reflective our planet is.

For the first time in India, a state government is using satellites to assess lost crops so that farmers can benefit from speedy insurance payouts.

Satellite data is being harnessed by researchers at the University of Illinois for a more complete picture of cropland and to estimate crop yield in the U.S. Corn Belt.

A new study with NASA participation finds that land ecosystems took progressively longer to recover from droughts in the 20th century, and incomplete drought recovery may become the new normal in some areas, possibly leading to tree death and increased emissions of greenhouse gases.

It is "extremely unlikely" 2014, 2015 and 2016 would have been the warmest consecutive years on record without the influence of human-caused climate change, according to the authors of a new study.

A new technique that merges data gathered by multiple satellites can be used to monitor agricultural water use and improve water quality assessments around the globe.

During the 20th century, the average temperature of the continental United States rose by almost 1 degree Fahrenheit (0.5 degree Celsius) -- everywhere, that is, except in the Southeast. There, until the 1980s, the temperature actually decreased slightly. Climate scientists dubbed this peculiar phenomenon the "warming hole," and it was the cause of much speculation. But beginning in the 1990s, temperatures in the Southeast began to warm again, and in the early years of the 21st century this warming has accelerated.
Weather-related disasters could affect around two-thirds of the European population annually by the end of this century. This could result in a 50-fold increase in fatalities compared to today if no measures are taken, according to a new study by the Joint Research Centre – the science and knowledge service of the European Commission.
Scientists are trying a new, interactive way to understand ocean current data with the help of high-resolution global ocean simulations.

Thanks to the satellite era, we recently witnessed the birth of one of the biggest icebergs on record. While the break-up of Antarctica's Larsen C ice shelf hit the headlines around the world, this dramatic event also presents scientists with a unique opportunity to learn more about ice-sheet stability.

Humans started to cultivate land around 10,000 years ago, so we must be pretty good at it by now. However, environmental concerns, sustainability, quotas, subsidies and paperwork make farming more challenging than ever. Satellites offer a solution to many of these problems, but how does the ordinary farmer tap into their potential?

Helheim Glacier is the fastest flowing glacier along the eastern edge of Greenland Ice Sheet and one of the island's largest ocean-terminating rivers of ice. Named after the Vikings' world of the dead, Helheim has kept scientists on their toes for the past two decades. Between 2000 and 2005, Helheim quickly increased the rate at which it dumped ice to the sea, while also rapidly retreating inland- a behavior also seen in other glaciers around Greenland. Since then, the ice loss has slowed down and the glacier's front has partially recovered, readvancing by about 2 miles of the more than 4 miles it had initially retreated.
A study published in Nature Scientific Reports by scientists from the Joint Research Centre (JRC), the UK's Centre for Ecology and Hydrology (CEH) and the University of Melbourne provides a first roadmap for country-specific accounting of soil resources.

A new NASA study shows that updrafts are more important than previously understood in determining what makes clouds produce drizzle instead of full-sized raindrops, overturning a common assumption.

Scientists are "very worried" that the melting of the Greenland ice sheet could accelerate and raise sea levels more than expected.
Currently the Greenland ice sheet is adding up to 1mm a year to the rise in the global average level of the oceans.

UNOSAT recently undertook the analysis of the largest area in its IDPs mapping histoy. This endeavor started in November 2016 in response to requests from partners such as the UN High Commissioner for Refugees (UNHCR) to support critical humanitarian response, and led to the scrutiny of some 11,500 square kilometers of Syrian lands.

In early July 2017, a massive section of ice split off from Antarctica's Larsen C ice shelf. This was captured by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the NOAA/NASA Suomi National Polar-orbiting Partnership (NPP) satellite.

Geoscience Australia is today releasing the sea floor mapping data collected during the first phase of the search for missing Malaysia Airlines flight MH370.
A new study gives the first observational evidence that the southern Amazon rainforest triggers its own rainy season using water vapour from plant leaves. The finding helps explain why deforestation in this region is linked with reduced rainfall.
