Last fall, circling the summit of an active volcano, a small aircraft moved us toward a future where remote but hazardous volcanoes are consistentl…
Collectively home to more than 1 million people, the Pacific island nations of Fiji and Tonga are frequently threatened by the impacts of climate change and natural hazards. In the aftermath of a disaster, these islands work hard to assess, identify and quantify risks and begin the recovery process.
Fiji and Tonga have taken many efforts to gather info…
This paper examines the powerful role that satellite-derived Earth observations (EOs) can play in understanding and preparing for intensified heat extremes. Heat extremes like in the boreal summer of 2021 triggered mass death in ecological systems, pushed engineered systems to the breaking point, and threatened health and well-being of people acros…
Evapotranspiration – the transfer of water from the ground into the air through a combination of evaporation and transpiration – increased globally by 10% between 2003 and 2019, according to new research.

The study, published in Nature, finds that the change is mainly driven by the world’s land surface heating up. This confi…
NOAA today announced that Raytheon Intelligence and Space has been chosen to design and develop the Earth Prediction Innovation Center (EPIC), an extramural center that will unite academia, industry and government to help create the most user-friendly and user-accessible comprehensive Earth modeling system.

Researchers have developed a global earthquake monitoring system that uses the Global Navigational Satellite System (GNSS) to measure crustal deformation.
The monitoring system within seconds can rapidly assess earthquake magnitude and fault slip distribution for earthquakes of magnitude 7.0 and larger, making it a potentially valuable tool in earthqua…
The United Nations Office for Outer Space Affairs (UNOOSA) and the Centre for Space Science and Technology Education for Asia and the Pacific (Affiliated to the United Nations) are launching a Massive Open Online Course (MOOC) on “Geospatial Applications for Disaster Risk Management”. This MOOC is a free and flexible online training programme available…

While state and federal officials are looking ahead and worrying about the coming fire season and how to more quickly get in front of fast-moving blazes, a University of California, Berkeley, professor argues that the tools for rapid detection are already here.
A weather satellite, GOES 17 (GOES West), sits above California taking ph…
Technologies to reflect some of the sun's rays away from Earth, as a way to cool future runaway climate change, are moving closer to becoming a reality

Technologies to reflect some of the sun's rays away from Earth, as a way to cool future runaway climate change, are moving closer to becoming a reality, and rules are needed now to go…
Scientists at Skolkovo Institute of Science and Technology (Skoltech), together with colleagues from the Karl-Franzens University of Graz & the Kanzelhöhe Observatory (Austria), Jet Propulsion Laboratory of California Institute of Technology (USA), Helioresearch (USA) and Space Research Institute of the Russian Academy of Sciences (Russia) developed…

As 2020 began, Australia was stunned by the worst bushfires on record. Six months later we are weathering the coronavirus pandemic sweeping the globe.
This year, perhaps more than ever before, decision-makers, emergency services, health providers and threatened communities have needed fast, reliable information to unde…
WMO has issued its annual Airborne Dust Bulletin on the incidence and hazards of sand and dust storms, which have been highlighted by a massive Saharan plume which has blanketed many parts of the Caribbean.
This dust plume arrived from North Africa in the Eastern Caribbean on June 17. It has since affected a wide spatial extent of the greater Caribbean…

Earthquakes, volcanic eruptions, tsunamis, explosions, and other events on Earth’s surface generate waves that travel upwards through the atmosphere. A recent article in Reviews of Geophysics explores how these events are detected by different instruments and the prospects of using these to monitor natural h…

MANILA — For the Philippines, the COVID-19 pandemic wasn’t the only disaster to hit the country in 2020. The year started out with a volcanic eruption and closed with two magnitude 6 earthquakes, one of them striking on Christmas morning. In between came Typhoon Goni, a late-season superstorm that was the strongest in the world last…
