Even as temperatures rise on Earth’s surface and in the lower atmosphere, the planet’s upper atmosphere has cooled dramatically.
Satellite Launch Pollution Rapidly Accumulating in the Upper Atmosphere
The potent pollution from so-called “megaconstellation” satellite systems launched en masse into space since 2019 will account for nearly half (42%) of the total climate impact of space sector pollution by the end of the decade, finds a new study led by UCL researchers.
Short Exposures to Common Air Pollutants Shown to Have Distinct Impacts on Lung Function and Brain Activity
New research by a collaboration of UK‑based scientists has revealed that common indoor and outdoor air pollutants can alter both brain and respiratory function within just four hours of exposure, offering key insights into how air pollution impacts brain health and may contribute to dementia risk.
Sea Level Rise is Swallowing Mid-Atlantic Farmland Faster Than Expected, Study Finds
Ghost forests, the cemetery-like groupings of dead trees killed by saltwater intrusion, have become haunting symbols of sea level rise overtaking land along the Mid-Atlantic coast.
Study Finds Wetter Storms Mean Drier Conditions Over Time
A Dartmouth study shows that annual rainfall in much of the world has consolidated over the past four decades into heavier storms with longer dry periods in between.
Protected Area Managers Across Europe are Adapting to Climate Change
New research shows how climate change is reshaping protected area management, though more funding and scientific knowledge are needed to facilitate the process.
Combined Short-Term Effects of Air Pollutants Linked to 146,500 Premature Deaths per Year in Europe
Fine particles (PM₂.₅) were associated with around 79,000 preventable deaths, followed by nitrogen dioxide (NO₂), ozone (O₃) and coarser particles (PM₂.₅-₁₀, particles with a diameter between 2.5 and 10 micrometres).
UC Irvine Team Identifies Where Renewable Hydrogen Delivers the Greatest Social Benefit
Renewable electrolytic hydrogen produced by using electricity drawn from wind and solar sources delivers its greatest societal value when applied to steelmaking, transoceanic shipping and long-haul heavy-duty trucking, according to University of California, Irvine researchers.
For Most US Drivers, EVs Offer Emissions Benefits and Cost Savings
Despite regional variability in climate, electricity sources, congestion, and the wide variation in individual driving patterns, electric vehicles generate less greenhouse gas emissions and do not cost more than comparable gas-powered vehicles for drivers and vehicle fleet owners in most parts of the United States, according to a new study...
Climate Change: How Oxygen Deficiency Changes Metabolic Processes in the Ocean
A new study reveals how sulfur compounds are metabolized under oxygen-deficient conditions – and which microorganisms are responsible.
