The birds stopped singing, the air grew heavy, and an unusual silence settled over their village in Minas Gerais, a southeastern Brazilian state where forested hills give way to the winding Doce River.  A mining dam owned by Samarco — a joint venture between Brazilian company Vale and Anglo-Australian giant BHP Billiton — burst upstream near the town of Mariana, unleashing a to

Japan deployed troops Wednesday to help contain a surge of bear attacks that have terrorized residents in a mountainous region in the northern prefecture of Akita.  Reports of sometimes deadly encounters with brown bears and Asiatic black bears are being reported almost daily ahead of hibernation season as the bears forage for food.  Since April, more than 100 people have been injured and at least 12 killed in bear attacks across Japan, according to Environment Ministry statistics at the end of

NASA releases new photos of interstellar comet 3I/ATLAS

NASA unveiled close-up pictures on Wednesday of the interstellar comet that’s making a quick one-and-done tour of the solar system.  Discovered over the summer, the comet known as 3I/Atlas is only the third confirmed object to visit our corner of the cosmos from another star.  Three NASA spacecraft on and near the red planet zoomed in on the comet as it passed just 18 million miles (29 million kilometers) away, revealing a fuzzy white blob.

The world's climate leaders are conceding that Earth's warming will shoot past a hard limit they set a decade ago in hopes of keeping the planet out of a danger zone.  United Nations officials, scientists, and analysts are pinning their hopes on eventually forcing global temperatures back below the red line they set in the 2015 Paris Agreement, which sought to limit warming to 1.5 degrees Celsius (2.7 Fahrenheit) since preindustrial times.  In the way climate science uses the term, it doesn't me
