A failure to clean and maintain its nets led to the net pen collapse at Cooke Aquaculture’s Cypress Island facility this summer and the escape of 100,000 more Atlantic salmon than originally reported. That’s the conclusion of an investigation by three state agencies into the August incident.

Many people are familiar with Google Street View, the online map that allows you to take a virtual walk or ride through a neighborhood. Now there’s a similar tool that lets you float down local rivers and waterways.

Many medium-sized businesses that consume large amounts of electricity may want to shrink their reliance on fossil fuels by committing to using solar or wind power. But their needs are often beyond what their local utility can provide from fully renewable sources. A Seattle startup has launched a new online marketplace to address these issues and support the growth of clean energy developments, by matching smaller investors with projects that meet their needs.

Washington state has some of the most beautiful mountains in the world for winter sports – and also the most deadly. Last year, more people died in avalanche accidents here than in any other state in the nation.

Feeling out of place takes on whole new dimension when you’re in a foreign country. Perhaps no one understands this more than new immigrants and refugees.

A public hearing on Gov. Jay Inslee’s proposal to tax fossil fuel emissions takes place Tuesday in Olympia. A coalition of environmental groups is urging people to go and organizing carpools to ensure a strong turnout.

As the state legislative session begins Monday, climate activists are out in full force in Olympia. They’re urging lawmakers to take bold steps to slow global warming.

One of the biggest mysteries among people working on salmon recovery in Puget Sound and the Salish Sea is what happens to juvenile fish once they head for the ocean. Survival rates of Chinook, Coho and Steelhead have all declined since the 1980s, but resource managers don’t know why. A new grant from Microsoft is using artificial intelligence to greatly improve the computer models used to tackle the question.
