climate change

A tall rectangular building juts out of a mountainside on a Norwegian island just 800 miles from the North Pole. Narrow and sharply edged, the facility cuts an intimidating figure against the barren Arctic background. But the gray building holds the key to the earth's biodiversity.

Scientists today laid out a truly worst-case scenario for global warming — what would happen if we burned the Earth's entire supply of fossil fuels.

Virtually all of Antarctica's ice would melt, leading to a 160- to 200-foot sea level rise.

"If we burn it all, we're going to melt it all," says Ken Caldeira, a climate scientist at the Carnegie Institution for Science.

Melting glaciers and dry lakebeds may seem to be a purely negative result of global climate change, but they’ve had a positive impact for one group of people: archaeologists.

As previously inaccessible areas become exposed, thousands of new artifacts are being uncovered, leaving archaeologists scrambling to keep up and preserve what they can.

President Barack Obama becomes the first sitting president to set foot on U.S. soil north of the Arctic Circle on Wednesday. Marcie Sillman talks to Nadine Fabbi, managing director of the Canadian Studies Center at the University of Washington, about why the Arctic is increasingly important to U.S. foreign policy.

President Barack Obama is coming to Alaska later this month.

The White House released a video Thursday morning to explain why he will be the first sitting president to visit Alaska’s Arctic. 

The folksy video (it starts with the president saying, “Hi, everybody”) features dripping glaciers, raging wildfires and Alaska Natives hanging salmon to dry.

Mt. Hood’s Timberline Resort is the only place offering a full summer ski season in North America. But not this year. The resort closed to the public on August 2 -- five weeks earlier than normal. And that’s after a dismal winter ski season.

Pope Francis today issued a sweeping 184-page papal letter, writing that climate change is a global problem with far reaching environmental and social consequences — especially for the poor. He blamed apathy and greed and called on developing countries to limit the use of nonrenewable energy and to assist poorer nations.

Protesters of Arctic drilling have run afoul of the ocean environment in their own small way.

In addition to assembling a flotilla of kayaks on Seattle's Elliott Bay last weekend, the activists brought in a construction barge. It's a solar-powered platform for protests against Shell Oil's plans to drill in the Arctic Ocean. But the protesters anchored their solar barge over one of Seattle's most popular sites for scuba diving.

Seattle planning officials say the Arctic drill rig at the Port of Seattle has to leave or get a new permit by June 4. 

The city issued a notice of violation to the Port of Seattle, Shell Oil and Foss Maritime on Monday afternoon.

The notice says the port's permit is only good for cargo ships, not oil rigs like the Polar Pioneer.

Shell Oil pulls into Elliott Bay, the University of Washington pulls out of coal and President Obama is pulled in two directions. KUOW's Bill Radke debates carbon and its alternatives with environmentalist Bill McKibben, Alaska North Slope Port Authority executive director Paul Fuhs and panelists Eli Sanders, Chris Vance and Joni Balter.

Plus: Should we ban smoking in Seattle parks? Do Washington legislators deserve a pay raise? And do Seattle "brogrammers" deserve blame for a changing Seattle?

Student activists Angela Feng, Sarra Tekola and Alex Lenferna of Divest UW appear before the UW Board of Regents on March 12, 2015 to urge the university to get rid of its coal investments.

Ross Reynolds speaks with economics reporter Jon Talton about climate change's affect the economy of the Pacific Northwest.

A snowpack that is less than 20 percent of the normal amount has farmers and ranchers in southern Oregon worried, but the region’s rafting guides say in spite of the limited snowfall they expect to have plenty of water to float on this summer.

Pete Wallstrom, a guide and owner of Momentum River Expeditions, says he’s getting lots of calls from clients wondering if they should cancel their trips on Oregon’s iconic Rogue River due to drought.

The Antarctic is far away, freezing and buried under a patchwork of ice sheets and glaciers. But a warming climate is altering that mosaic in unpredictable ways — research published Thursday shows that the pace of change in parts of the Antarctic is accelerating.

China's top weather scientist has made a rare official acknowledgement: climate change, he says, could have a "huge impact" on the country's crop yields and infrastructure.

Zheng Guogang, the head of China's meteorological administration, tells Xinhua news agency that China is already experiencing temperature increases that outpace those in other parts of the world.

As a result, China — the world's biggest emitter of greenhouse gases — faces a possible "ecological degradation," he says.
