By August 25, three-quarters of the territory was in at least moderate drought, with extreme drought covering 44 percent and some areas receiving less than 20 percent of their usual rainfall. Water shortages have forced rationing, while farmers are losing crops and ranchers are running low on hay. The situation has become serious enough to trigger both local and federal disaster declarations.

Scientists also found a deep basin beneath Tillamook that could trap seismic waves and intensify the shaking even further. Sun, 30 Aug 2026 00:12:10 EDT https://www.sciencedaily.com/releases/2026/08/260828082350.htm https://www.sciencedaily.com/releases/2026/08/260827010459.htm Beneath the rocky slopes of Mount Timpanogos lies far more ice than anyone walking across the surface might suspect. Researchers used gravity measurements to map the buried glacier in 3D and found it is about 83% ice, with enough frozen water to fill 600 Olympic swimming pools. Their findings suggest rock glaciers form as falling debris buries persistent snow and preserves it for thousands of years. Similar formations around the world may collectively store tens of gigatons of hidden water.

Scientists expect two more huge sections could soon detach, potentially removing about 22 percent of the remaining ice tongue. Wed, 26 Aug 2026 08:39:11 EDT https://www.sciencedaily.com/releases/2026/08/260826055503.htm https://www.sciencedaily.com/releases/2026/08/260823094154.htm Scientists may have solved the mystery of why Antarctica froze millions of years before the Arctic. Slow-moving waves deep inside Earth gradually lifted East Antarctica, building mountains and a high plateau where snow and ice could survive even in a much warmer world. Once glaciers took hold, their bright surfaces reflected sunlight and helped cool the region further. Tue, 25 Aug 2026 13:12:46 EDT https://www.sciencedaily.com/releases/2026/08/260823094154.htm https://www.sciencedaily.com/releases/2026/08/260823094145.htm A huge section of Greenland’s Petermann Glacier has snapped off, forming an ice island about the size of Manhattan. Satellites watched cracks spread rapidly before the 76-square-kilometer slab finally broke free on August 4. It is the glacier’s biggest calving event since 2012, and scientists say two even larger pieces could eventually follow. The rare Arctic iceberg will now be tracked as it drifts, breaks apart, and potentially affects shipping routes.

The ancient landscape could also help explain why enormous sections of North America’s geological record appear to be missing. Thu, 20 Aug 2026 23:43:10 EDT https://www.sciencedaily.com/releases/2026/08/260820202828.htm https://www.sciencedaily.com/releases/2026/08/260820002454.htm The “Asian Water Tower” is losing roughly 24.2 billion tonnes of groundwater every year, with some of the worst declines hitting densely populated farming regions. Glacier melt may temporarily soften the crisis around the 2060s, but without changes in water use, researchers expect depletion to accelerate afterward. Thu, 20 Aug 2026 05:21:01 EDT https://www.sciencedaily.com/releases/2026/08/260820002454.htm https://www.sciencedaily.com/releases/2026/08/260816044839.htm A newly discovered Arctic process can dramatically boost the number of particles that help form clouds. Near melting sea ice, sunlight reacts with chemicals released by the ocean, algae, and ice, causing cloud-seeding particles to multiply by as much as 50 times in a day. Because the active ice-edge region is growing as sea ice retreats, the effect could become increasingly important. Scientists now want to add the process to climate models to see how much it could reshape Arctic warming.

Using advanced long-read DNA sequencing, researchers uncovered more than 19,000 large genetic differences in brown tree snakes, many concentrated in genes tied to immunity and smell. This overlooked diversity may have helped a population founded by only a few snakes survive inbreeding, adapt to a new environment, and multiply to extraordinary densities.

New evidence shows that an asteroid about 160 meters wide struck the seabed roughly 43 to 46 million years ago. The impact triggered a tsunami more than 100 meters high and left behind a crater that geologists debated for years.

Research found that several popular sport fish, including trout, bass, perch, and whitefish, tend to decline in darker waters. Meanwhile, walleye and northern pike often become more abundant because they are better adapted to low-visibility conditions. The shift could change both lake ecosystems and the fishing experience for millions of anglers.

In Japan’s wetland farming landscapes, shelterbelts benefited some birds but sharply reduced grassland and wetland species that need open space. Researchers found grassland bird abundance dropped by more than 70% near shelterbelts.

Unlike bees that nest underground, they have few ways to escape dangerous heat. Researchers also discovered that tropical bees are particularly vulnerable, even when they are already adapted to hot environments. The findings suggest bee behavior could be a key factor in determining which species survive a warming world.
