New Guinea, the world’s second-largest island, harbors an extraordinary variety of plant life across more than a dozen distinct ecoregions, including seasonally dry savannas, tropical rainforests, and lowland swamp forests.

Humans are exerting increasing influence over how water moves through lakes, rivers, soil, and the subsurface, and a new NASA study shows where those effects are greatest. Using more than two decades of satellite measurements of subtle changes in Earth’s gravity, the researchers sharpened the picture of how—and why—terrestrial water storage has changed. This map
As the air grows cooler and days shorter, brown bears prowl the Carpathian Mountains of southern Poland with the goal of fattening up ahead of winter hibernation. In a more conspicuous sign of autumn, beech and other deciduous trees blanketing the hillsides start to sport reds and golds. The seasonal transformation was underway in southeast
Unlike a tornado or thunderstorm that can deliver destruction in minutes, El Niño exerts its influence over many months. This year, a drought accompanying El Niño has left the Amazon rainforest primed to burn, and scientists say the region has entered the early stages of what they think will be a long and severe fire
Hurricane Simon, the latest in a long progression of tropical cyclones in the Eastern Pacific this season, passed close to the Mexican coast as a category 4 storm on October 11, 2026.
