climate change

The Coast Guard icebreaker HEALY has returned to Seattle. The summer ice has gotten easier to navigate, which made it possible for the HEALY to travel alone.

An American icebreaker has returned home to Seattle after a historic mission to the North Pole.

The U.S. Coast Guard cutter Healy broke its first ice floe in August, just north of Alaska.

Much of the forestland above the Illinois River in Southwest Oregon is a tangled mess of manzanita, shrubby hardwoods and ceanothus. Bushwhacking through it is a branch-to-the-face, boot-snagging, poison-oaky horror.

And this is one of the easy spots, says Portland State University Ph.D. student Charles Maxwell.

“Yeah, this one is a pretty accessible site relatively. Some are quite a bit further in,” he says.

Scientists believe that Kivalina, population 457, will be the first casualty of climate change in the U.S., and that it will be inundated by sea water by 2025.

Ross Reynolds talks to journalist Elizabeth Arnold about how rural Alaskan communities are dealing with fast rising tides and severe storms caused by climate change.

On Thursday morning, Patricia was a relatively small Category 1 hurricane. By Friday afternoon, it was the most powerful storm ever recorded in the Western Hemisphere.

Is climate change to blame for this record-breaking storm's ferocious rise?

The answer is complex, and shows why it's so hard to tie a single weather event to global warming.

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.

Protesters buzz along the West Seattle shore as the Polar Pioneer is hauled toward the Port of Seattle's Terminal 5 on Thursday, March 14, 2015.

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.

David Hyde speaks with Vox.com writer David Roberts who says student activists at the UW and elsewhere are changing the debate about climate change by making it a moral issue.
