REDDING, Calif. (AP) — A rare fire tornado that raged during this summer's deadly Carr Fire in Northern California was created by a combination of scorching weather, erratic winds and an ice-topped cloud that towered miles into the atmosphere, according to a study announced Wednesday. The churning...

Climate Change is more than rising thermometers, wildfires, droughts and storms; it even has a hand in altering whale songs, flowering plants and civil war. Near Antarctica, whales are singing in deeper tones to cut through the noise of melting icebergs. (Jean-Yves Royer/CNRS-UBO-IUEM Geosciences Ocean via AP)

WASHINGTON (AP) — Near Antarctica, whales are singing in deeper tones to cut through the noise of melting icebergs. In California, a big college football rivalry game was postponed until Saturday because of smoky air from wildfires. And Alaskan shellfish were struck by an outbreak of warm water...

BERLIN (AP) — The European Union's executive branch proposed Wednesday that the bloc should cut its emissions of greenhouse gases to net zero by 2050, a measure that scientists say needs to be adopted worldwide in order to avoid catastrophic global warming. The European Commission is the first...

GENEVA (AP) — A top U.N. scientist on Thursday shrugged off an online quip from U.S. President Donald Trump that questioned global warming, saying a U.S. government report will show the "fundamental impacts of climate change on the U.S. continent." Officials at the World Meteorological Organization...

A study of polar bears in the Chukchi Sea between Alaska and Russia finds that the population is thriving for now despite a loss of sea ice due to climate change. Lead author Eric Regehr of the University of Washington says the Chukchi may be buffered from some effects of ice loss. Regehr says polar bears can build fat reserves and the Chukchi's abundant seal population may allow bears to compensate for a loss of hunting time on ice. (AP Photo Eric Regehr via AP)

ANCHORAGE, Alaska (AP) — The first formal count of polar bears in waters between the United States and Russia indicates they're doing better than some of their cousins elsewhere. Polar bears are listed as a threatened species because of diminished sea ice due to climate change. But university and...

A study released on Wednesday, Nov. 14, 2018 says that between being tripped up by downtown and the bigger effect of massive paving and building up of the metro area to reduce drainage, development in Houston on average increased the extreme flooding risk by 21 times.

WASHINGTON (AP) — Humans helped make recent devastating U.S. hurricanes wetter but in different ways, two new studies find. Hurricane Harvey snagged on the skyscrapers of Houston, causing it to slow and dump more rain than it normally would, one study found. The city's massive amounts of paving had...

WASHINGTON (AP) — Both nature and humans share blame for California's devastating wildfires, but forest management did not play a major role, despite President Donald Trump's claims, fire scientists say. Nature provides the dangerous winds that have whipped the fires, and human-caused climate...

LA PAZ, Bolivia (AP) — The snow appears to be pristine on the Andean peaks that loom above Bolivia's capital, but even here ash and smog reach up to a remote plateau that is home to the world's highest atmospheric observatory. It's an ideal site for a team of international scientists who collect...

This illustration provided by Carbon Engineering in October 2018 shows one of the designs of the company's air contactor assemblies to remove carbon dioxide from the atmosphere. Carbon Engineering acting chief scientist David Keith, a Harvard University professor, said “in the long-term, carbon removal will make sense to reduce atmospheric carbon burden, but only once emissions have been brought near zero. The idea that humanity might continue huge fossil emissions while simultaneously balancing them with removal is nutty _ you plug the leaks before bailing the boat.” (Carbon Engineering via AP)

WASHINGTON (AP) — The nation needs to ramp up efforts to suck heat-trapping gases out of the air to fight climate change, a new U.S. report said. The report Wednesday from the National Academy of Sciences says technology to do so has gotten better, and climate change is worsening. By mid-century,...
