Even as temperatures rise on Earth’s surface and in the lower atmosphere, the planet’s upper atmosphere has cooled dramatically.
A New Study Explains How Carbon Dioxide Cools the Upper Atmosphere—and Warms Earth Below

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.
Extreme Weather Events Accelerating Tidal Wetland Loss
Tidal wetlands are critical, yet vulnerable ecosystems. Tidal marshes, mangrove forests, and tidal flats support biodiversity, protect against flooding and storm surges, sequester carbon, and improve water quality.
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.
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).
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.
