Is it ethical to go whale watching? Boats sometimes interfere with whales’ ability to hunt and eat. But whale watching can also connect people with conservation.

And that could help the group of orcas that are resident in Puget Sound. The recent arrival of another baby orca in that so-called southern resident group (see photos in the slideshow above) has tickled whale watchers in the San Juan Islands.

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.

In California's blazing hot San Joaquin Valley, millions of pistachio trees are now buried in clusters of small pinkish-green fruits — what would seem like a bumper crop.

But for many growers of the popular nut, the season is shaping into a disaster. Jeff Schmiederer, who farms 700 acres of family-owned pistachio trees on the western side of the San Joaquin Valley, says about 90 percent of the nuts he has sampled from his trees are hollow — what growers call "blanks."

A southwest Washington man has pleaded guilty to poaching bigleaf maple trees from U.S. Forest Service land. Ryan Anthony Justice entered his plea Thursday in federal court in Tacoma.

This wildfire season has hit northwest tribal lands particularly hard. Firefighters’ first priority is “life and property.” But some tribal members wonder why protecting some kinds of property—like farms and even second homes— comes before tribal forest land.

Scientists know a little more about how big earthquakes happen, from research published Thursday in the journal Science.

The study from the U.S. Geological Survey looked at a number of subduction zones, but not the Cascadia Subduction Zone, off the Northwest coast. The research doesn't change predictions that there's a one-in-three chance of a big quake in the Northwest in the next 50 years.

Jeannie Yandel talks to former Seattle Mayor Mike McGinn about why he is calling on the Gates Foundation to divest from fossil fuel companies.

Jeannie Yandel talks with Seattle Times science reporter Sandi Doughton about her story on the alarming melting of Northwest glaciers due to hot weather and low snowpack. Scientists say glaciers across the North Cascades could shrink by as much as 10 percent this year.

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.

U.S. Secretary of Agriculture Tom Vilsack announced a key step Friday in completing a 1,200 mile trail from Glacier National Park to the Pacific Ocean.

Hikers already use what's called the "Pacific Northwest Trail," but it has gaps, and isn't fully built out.

Vilsack has named 23 advisers to help finalize the trail corridor, including Jon Knechtel with the Pacific Northwest Trail Association.

Todd Mundt speaks with Richard Harvey, a volunteer firefighter working on the Okanogan complex fires. After the "hot, dirty work" on the fire line that gets all the attention, he says,“Mop up is the dirty part that they don’t show on the television.”

Mount McKinley is reverting to its native Alaskan name, Denali. So how about renaming Mount Rainier? Plus, Seattle teachers, who might strike next week, are in a union – should Uber drivers be, too? And which words are too offensive for the college classroom?

Bill Radke discusses the week’s news with Eli Sanders, Knute Berger and Erica C. Barnett.

Waterside Energy announced Wednesday plans to expand its proposed energy project in the Columbia River town of Longview, Washington.

In addition to a crude oil refinery, the company now wants to build a $450 million transload facility for liquid propane and butane gas, also known as LPG for liquified petroleum gas.

One unit train – about 115 tank cars long – would arrive from Canada at the facility every day, Waterside Energy CEO Lou Soumas said.

“Then loading it on gas carrier to go to the Asian markets,” he said. “The customer base is export.”

Fishing Restrictions Temporarily Lifted In NE Oregon

Sep 3, 2015

Fishing restrictions on 10 bodies of water in Northeast Oregon have been temporarily lifted effective immediately, according to the Oregon Department of Fish and Wildlife. The ODFW announced the relaxed rules, which will impact lakes and ponds in Baker, Union, Umatilla and Wallowa counties, Wednesday.
