Azara’s owl monkeys, a small primate species found in South America, are heavier today than those that lived a quarter-century ago, and evidence suggests that rising temperatures might have driven the weight gain, according to a Yale-led study of a wild population.

Alaska’s Cook Inlet was home to nearly 1,300 beluga whales in the late 1970s, but today the population hovers around 300.

As climate change intensifies extreme weather and environmental conditions across the country, about 65% of U.S. adults are concerned that climate change will negatively affect their personal health, according to a new study published in Health Affairs Scholar.

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.

Even as temperatures rise on Earth’s surface and in the lower atmosphere, the planet’s upper atmosphere has cooled dramatically.

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.

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.

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.

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).

New research shows how climate change is reshaping protected area management, though more funding and scientific knowledge are needed to facilitate the process.
