- 1New Engine Could Let Satellites Refuel Using Earth's Atmosphere●New Satellite Engine Could Use Earth's Atmosphere to Stay in Orbit Indefinitely
Researchers have developed a satellite propulsion engine designed to scoop in molecules of air from the upper atmosphere and use them as propellant, allowing satellites in very low orbit to maintain their altitude indefinitely without carrying limited fuel. The approach could enable longer-lived Earth-observation missions and cheaper operations at low altitudes, where atmospheric drag normally forces satellites to burn fuel or deorbit.
- 2EU climate service warns wildfire smoke and pollution cross borders●The EU’s Copernicus Atmosphere Monitoring Service: “CAMS Atmosphere Watch shows air pollution knows no borders. Wildfire
The EU's Copernicus Atmosphere Monitoring Service says its CAMS Atmosphere Watch programme shows that air pollution ignores national borders, with wildfire smoke, ozone and dust capable of travelling thousands of kilometres to affect communities far from their sources. The service highlights cross-border monitoring as essential for tracking long-range pollution threats across Europe and beyond.
- 3Environment defenders risking their lives for climate and food●# environment defenders are putting their lives on the line in order to protect our atmosphere and # food . # globalWarm
Environmental defenders are being highlighted for risking their lives to protect the atmosphere and food systems, with calls for greater respect and protection framed as a human rights issue. The message ties their work to global warming and climate change, arguing those who defend land and ecosystems deserve safety and support amid rising threats to activists worldwide.
- 4New analysis tracks global air quality and pollution flows in 2026▼Atmosphere Watch: new analysis tracks global air quality and transboundary pollution in 2026
The Copernicus Atmosphere Monitoring Service has released a new analysis monitoring global air quality and the cross-border movement of pollution for 2026. The report tracks how pollutants travel between countries, offering updated data on particulate matter and other airborne contaminants. The findings matter for policymakers dealing with air quality standards, since pollution increasingly crosses national boundaries and requires international coordination to address.

Antarctic winter sea ice has fallen to a record low at its annual peak, marking roughly the third consecutive year of unprecedented lows. Scientists including Will Hobbs of the University of Tasmania say the big question is how sensitive the global climate system is to this ongoing loss of sea ice, and warn researchers are still working to understand the consequences.
- 6El Niño's atmospheric feedback loops explained anew●Every few years, a disturbance in the Pacific Ocean is amplified by feedback mechanisms in the atmosphere, unleashing he
Scientists at New Scientist are explaining how a periodic disturbance in the Pacific Ocean is amplified by atmospheric feedback mechanisms, releasing heat and driving extreme weather across the globe. The description matches El Niño, the climate pattern that recurs every few years and alters rainfall, storms and temperatures worldwide.
- 7Prince George's Sphere project wins major local business commitments●Braveboy: Prince George's Sphere project secures major local business commitments
Prince George's County executive Aisha Braveboy announced that the proposed Sphere entertainment venue project has secured major commitments from local businesses. The announcement signals growing local commercial backing for the large-scale development, though details of which businesses are involved and what they have pledged have not been made clear.

- 9Current El Niño could be strongest in 1,000 years●The current El Niño is likely to be the strongest in at least 1,000 years and will pile extra heat into an atmosphere in
Climate commentators warn the current El Niño is likely to be the strongest in at least 1,000 years, adding further heat to an atmosphere already warming rapidly from human-caused climate change. On that basis, 2027 is expected to "blow apart" previous global temperature records. The warning is drawing attention as extreme weather and record heat continue worldwide.

Antarctic sea ice has again reached a record low for its winter peak, continuing a trend seen over the past three years. Scientists, including Will Hobbs of the University of Tasmania, warn that the planet's climate system may be more sensitive to the loss of sea ice than previously understood, and researchers are still working to quantify the wider consequences of the continued decline.
- 11From Greenland to the Falklands: Where Do Europe's Strategic Interests End?▼From Greenland to the Falklands: Where Do Europe’s Strategic Interests End?
A new analysis asks how far Europe's strategic interests actually stretch, drawing a line from Greenland in the Arctic to the Falkland Islands in the South Atlantic. The piece examines the boundaries of European security commitments and overseas territories at a time when geopolitical competition is testing traditional alliances and spheres of influence.
