NAIROBI, Kenya — Leopards often produce a unique, deep, guttural roar commonly described as “sawing” due to its resemblance to the sound of a person sawing wood by hand. Researchers…
NAIROBI — Cheetahs are known to be selective in their feeding habits — “clean eaters” that only go after the prime parts of their kill, such as the liver. But…
In October 2020, the hoofbeats of American bison thumped across the prairie of the Rosebud Reservation for the first time in more than a century. Years in the works, the…
Next-generation geothermal technologies are gaining steam as a source of clean, renewable energy and an alternative to fossil fuels. With demonstration projects across the globe now showing strong potential, enhanced…
A new study has concluded that the decline in Grauer’s gorillas in a sector of their main stronghold in the Democratic Republic of Congo was the result of the impacts…
For many years, the North Atlantic Ocean warmed more slowly than other parts of the world. In 2023, that changed — dramatically. Over the last year and a half, North…
It sounds like a simple solution: Spread some crushed silicate rock atop the world’s vast agricultural lands to absorb atmospheric carbon and thereby tackle climate change at a large scale.…
Earth’s climate system continues to rapidly deteriorate, with global temperatures on track to far overshoot 2° Celsius (3.6° Fahrenheit) of warming by the end of the century — a mere…
A controversial experiment to field-test a way to quickly sequester more carbon in the world’s oceans has been pushed back until 2025, according to the Woods Hole Oceanographic Institution (WHOI).…
For sea ice scientists, September is the time for polar highs and lows. Around mid-month, the Antarctic winter sea ice approaches its highest extent, while the Arctic summer thaw melts…
WET’SUWET’EN, Canada — The pilot flew over squares of clear-cuts and tree plantations, then rolled the helicopter around Hudson Bay Mountain in north-central British Columbia. We were following directions from…
When Manuel Lopes-Lima set out to survey aquatic biodiversity on the Corubal River in 2022, he’d set his expectations very low. The river that straddles the West African nations of…
In the 2020 science-fiction novel The Ministry for the Future, author Kim Stanley Robinson imagines a near-future climate catastrophe in which a deadly heat dome stalls over India, killing millions…
July is the peak of melt season in the Arctic. The sun is high and shines for almost 24 hours a day. Air and water temperatures rise above freezing. Rapid…
Regional deployment of marine cloud brightening off the U.S. West Coast would be far less effective in the warmer world of 2050, and if implemented, could unleash higher temperatures in…
As climate change rapidly advances, with 2023 and 2024 vying for the hottest year on record, solar radiation modification (SRM) geoengineering strategies are gaining momentum as short-term climate fixes. These…
This is Part Two of a two-part story. Find Part One here. In April, researchers from the University of Washington sprayed sea salt particles into the air off the California…
This is Part One of a two-part story. Find Part Two here. A 2023 study published in JGR Atmospheres found that implementing a global solar geoengineering project could slow the…
When José Rodrigues do Santos first saw the enormous canyons in Gilbués, in Brazil’s Piauí state, he didn’t imagine that he would spend the rest of his life there. He…
Monitoring and keeping track of snakes is a cumbersome task. Jeff Lemm knows the inefficiencies all too well. The herpetologist has been studying red diamond rattlesnakes (Crotalus ruber) for years.…
Inhabited termite mounds along the Buffels River in Namaqualand, South Africa, are an astounding 34,000 years old, according to a new study. Termites are a diverse group of insects that…
What do lakes tell us about life on the land surrounding it? When environmental DNA scientist Kristy Deiner and her team started thinking about this question, the answer seemed evident:…
KATHMANDU — When researcher Kumar Paudel from the NGO Greenhood Nepal received permission to carry out a genetic study to determine the distribution of the two species of pangolins in…
“We (humans) are trying to get under the skin of other species, trying to understand them on their terms. And the more we succeed, the more we discover a natural…
Beneath the Yucatán Peninsula, in southeastern region of Mexico, lies a vast network of flooded tunnels and caves. These intricate and shadowy labyrinths serve as subterranean rivers, constituting the sole…
A new study finds the terrestrial part of the Arctic has shifted from being a greenhouse gas sink to being a source. Another finds that El Niño undermines Antarctic ice shelves by intensifying melt from below, putting onshore glaciers at risk.
Scientists called for project ideas and scored them from reasonable to wild. While all agree cutting emissions needs action now, some of these methods of last resort could be tested, and one day be applied to save the polar region.
JAKARTA — Civil society organizations in Indonesia staged protests in late April to raise awareness of a planned nuclear plant near Pontianak, capital of West Kalimantan province on the island…
With the rapid expansion of digital and AI tools, climate disinformation has become a major challenge for journalists and media organizations across the world. However, climate disinformation researchers say that…
Biological solutions offer hope for tackling human-caused pollution — but only if government and industry significantly support getting those solutions out of the lab and into the real world.
JAKARTA — In wildlife conservation management, the best species to focus on to maximize protection of a region’s biodiversity aren’t necessarily the most charismatic ones, a new study from Indonesia’s…
The Negros fruit dove was described from a single specimen collected in the Philippines in 1953 — then never seen again by scientists. Now, thanks to advances in DNA sequencing,…
