ANCHORAGE, Alaska (AP) — Alaska has been America's canary in the coal mine for climate warming, and the yellow bird is swooning. July was Alaska's warmest month ever, according to the National Oceanic and Atmospheric Administration. Sea ice melted. Bering Sea fish swam in above-normal temperatures...

ABOARD A NASA RESEARCH PLANE OVER GREENLAND (AP) — The fields of rippling ice 500 feet below the NASA plane give way to the blue-green of water dotted with irregular chunks of bleached-white ice, some the size of battleships, some as tall as 15-story buildings. Like nearly every other glacier on...

This March 26, 2019 photo shows the water level of the Colorado River, as seen from the Hoover Dam, Ariz. For the seven states that rely on the Colorado River that carries snowmelt from the Rocky Mountains to the Gulf of California, that means a future with increasingly less water for farms and cities although climate scientists say it's hard to predict how much less. The U.S. Bureau of Reclamation on Thursday, Aug. 15, 2019, will release its projections for next year's supply from Lake Mead, which feeds Nevada, Arizona and California. (AP Photo/Richard Vogel)

FLAGSTAFF, Ariz. (AP) — Snow swamped mountains across the U.S. West last winter, leaving enough to thrill skiers into the summer, swelling rivers and streams when it melted, and largely making wildfire restrictions unnecessary. But the wet weather can be misleading. Climate change means the region...

BERLIN (AP) — July was the hottest month measured on Earth since records began in 1880, the latest in a long line of peaks that scientists say backs up predictions for man-made climate change. The U.S. National Oceanic and Atmospheric Administration said Thursday that July was 0.95 degrees Celsius...

FILE - In this Sept. 9, 2011 file photo visitors view the dramatic bend in the Colorado River at the popular Horseshoe Bend in Glen Canyon National Recreation Area, in Page, Ariz. Some 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming draw from the Colorado River and its tributaries. Much of that originates as snow. A wet winter likely will fend off mandated water shortages for states in the U.S. West that rely on the river but won't erase the impact of climate change. Climate change means the region is still getting drier and hotter. (AP Photo/Ross D. Franklin, File)

Extreme swings in weather are expected as part of a changing climate, something Brad Udall, a water and climate research scientist at Colorado State University, has called "weather whiplash." The drought-stricken Southwest got a reprieve this year with average and above-average snowfall following a year that sent many states into extreme drought. Nearly empty reservoirs quickly rose, including Lake Mead and Lake Powell, the largest man-made reservoirs in the country that hold back Colorado River water. (AP Photo/John Locher, File)

Scientists of the institute say they proved plastic in the snow of the Alps and the Arctic. (Juerg Trachsel/WSL-Institut für Schnee- und Lawinenforschung SLF via AP)

BERLIN (AP) — Scientists say they've found an abundance of tiny plastic particles in Arctic snow, indicating that so-called microplastics are being sucked into the atmosphere and carried long distances to some of the remotest corners of the planet. The researchers examined snow collected from sites...
