SACRAMENTO, Calif. (AP) — With the smell of California wildfires in the air, President Donald Trump on Monday ignored the scientific consensus that climate change is playing a central role in historic West Coast infernos and renewed his unfounded claim that failure to rake forest floors and clear...

In this image proved by the European Space Agency, ESA, showing the glacier section that broke off the fjord called Nioghalvfjerdsfjorden, bottom, which is roughly 80 kilometers (50 miles) long and 20 kilometers (12 miles) wide, the National Geological Survey of Denmark and Greenland said Monday Sept. 14, 2020. The glacier is at the end of the Northeast Greenland Ice Stream, where it flows off land and into the ocean. Scientists with National Geological Survey see it as evidence of rapid climate change leading to the disintegration of the Arctic's largest remaining ice shelf. (European Space Agency via AP)

COPENHAGEN, Denmark (AP) — An enormous chunk of Greenland’s ice cap has broken off in the far northeastern Arctic, a development that scientists say is evidence of rapid climate change. The glacier section that broke off is 110 square kilometers (42.3 square miles). It came off of the fjord called...

Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus: hints there may be bizarre microbes living in the sulfuric acid-laden clouds of the hothouse planet. Two telescopes in Hawaii and Chile spotted in the thick Venusian clouds the chemical signature of...

A record amount of California is burning, spurred by a nearly 20-year mega-drought. To the north, parts of Oregon that don’t usually catch fire are in flames. Meanwhile, the Atlantic’s 16th and 17th named tropical storms are swirling, a record number for this time of year. Powerful Typhoon Haishen...

The world is getting closer to passing a temperature limit set by global leaders five years ago and may exceed it in the next decade or so, according to a new United Nations report. In the next five years, the world has nearly a 1-in-4 chance of experiencing a year that’s hot enough to put the...

Here we go again. America and the world are getting more frequent and bigger multibillion dollar tropical catastrophes like Hurricane Laura, which is menacing the U.S. Gulf Coast, because of a combination of increased coastal development, natural climate cycles, reductions in air pollution and man-...

FLAGSTAFF, Ariz. (AP) — It's something like a modern-day chuckwalla, strolling in sand dunes on an island in what now is the Grand Canyon region. That's how Steve Rowland, professor emeritus of geology at the University of Nevada, Las Vegas, and his fellow researchers interpret fossil footprints...

If you want to build a fire, you need three things: Ignition, fuel and oxygen. But wildfire in California is a much more complex people-stoked witch’s brew. The state burns regularly because of fierce autumn winds, invasive grasses that act as kindling, fire-happy native shrubs and trees, frequent...

Greenland lost a record amount of ice during an extra warm 2019, with the melt massive enough to cover California in more than four feet (1.25 meters) of water, a new study said. After two years when summer ice melt had been minimal, last summer shattered all records with 586 billion tons (532...
