For the past several years, Penn State geoscientist Sarah Ivory and her students have been among a team of scientists scaling the East African Rwenzori Mountains, collecting sediment core samples from lakes formed at the end of the last ice age as glaciers began receding in the region some 12,000 years ago.

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