Some 70 scientists, developers and emergency managers from across Europe came together at ECMWF from 15 to 17 March to drive forward a project that aims to provide forecasts of weather impacts, such as damage from wind storms, floods and heat waves.
In the U.S., efforts to curb acid rain in the 1990s had the unintended effect of increasing ammonia in the atmosphere.

Some climate models are suggesting that El Niño may return later this year, but for now, the Pacific Ocean lingers in a neutral "La Nada" state, according to climatologist Bill Patzert of NASA's Jet Propulsion Laboratory, Pasadena, California.
Volcanoes erupt, they spew ash, their scarred flanks sometimes run with both lava and landslides. But only occasionally. A less dramatic but important process is continuous gas emissions from volcanoes; in other words, as they exhale. A number of volcanoes around the world continuously exhale water vapor laced with heavy metals, carbon dioxide, hydrogen sulfide and sulfur dioxide, among many other gases. Of these, sulfur dioxide is the easiest to detect from space.

The Arctic has been losing sea ice over the past several decades as Earth warms. However, each year, as the sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates.

A novel airborne experiment over the flat agricultural landscape of the Netherlands recently simulated, for the first time, images that could be taken by radar satellites orbiting in tandem.

Atmospheric river storms are hailed as drought-busters when they bring needed rain and snow, but they have a well-known dark side: damaging floods. A new NASA study documents a second destructive force in these storms: high winds.

Following the appearance of a large crack in the ice shelf close to the Halley VI research station in Antarctica, information from the Copernicus Sentinel-1 and Sentinel-2 satellites helped to decide to close the base temporarily.

"We're seeing the loss of forests in many places," said Matthew Hansen, a professor at the University of Maryland. "Dynamics include increasing tropical deforestation, more frequent and severe boreal forest fires, disease in temperate forests and the commoditization of subtropical forests."

Kilauea Volcano on the island of Hawaii is one of Earth's most active volcanoes, drawing scientists and tourists alike from all over the world to study and witness its spectacular displays of nature. This month, a NASA-led science team is exploring Kilauea and the adjacent volcano Mauna Loa from the air, ground and space. Their goal: to better understand volcanic processes and hazards.

A novel way of using ESA's CryoSat mission has revealed how lakes beneath Thwaites Glacier drained into the Amundsen Sea - potentially the largest such outflow ever reported in this region of West Antarctica.

A Special Issue of the MDPI journal has been created and is open to the submission of both review and original research articles, related to the exploitation of spaceborne Earth observation (EO) and in-situ sensors for risk assessment from natural threats.

Climate change-driven glacial melt is causing landslides in alpine regions. Data from the Sentinel-1 satellite mission are being inserted into a new cloud computing system to monitor such hazards globally.

The microscopic size of phytoplankton, the plant-like organisms that live in the sunlit upper ocean, belies their importance in the global environment. They provide the food source for the zooplankton that ultimately feed larger animals ranging from small fish to whales. And like plants on land, phytoplankton use carbon dioxide from the atmosphere to grow and thrive through photosynthesis, which ultimately releases oxygen into the ocean and atmosphere.
Expansive forest fires have raged through Chile for some weeks now due to a long dry spell. On 25 January 2017, the Chilean National Office for Emergency (Oficina Nacional de Emergencia del Ministerio del Interior; ONEMI) activated the International Charter Space and Major Disasters to obtain up-to-date situation images of the disaster area to assist emergency services.

Approximately 345,000 or fewer chimpanzees remain in the wild, according to the International Union for the Conservation of Nature, a substantial decline from the more than two million that existed a hundred years ago. Humans' closest genetic cousins, chimpanzees are an endangered species, and scientists and conservationists are turning to the NASA-U.S. Geological Survey Landsat satellites to help bolster their efforts to preserve their forest homes.
