Danger from the catastrophic Fort McMurray, Alberta, wildfire won't end when the flames stop. Research from California fires that have burned through communities suggests such blazes leave a dangerous legacy of caustic ash and toxic metals. The USGS found ash left after California's wildfires in 2007 and 2008 was far more alkaline than ash from wood fires. Mixed with water, the ash was almost as caustic as oven cleaner.


Judge rejects feds' Columbia River salmon plan

A federal judge has ruled for the fourth time that the U.S. government's plan to recover salmon and steelhead in the Columbia River basin fails to address the federal hydropower dams' effect on fish. U.S. District Court Judge Michael Simon criticized the current plan for underestimating the effects of climate change on fish survival and gave NOAA two years to write a new plan.

Crater Lake is famous for its stunning blue and crystal-clear water, but that feature could be a thing of the past someday. Warming air temperature could threaten the water in Oregon's most-popular National Park, according to a new report by the USGS, the result of sustained climate change in the Pacific Northwest.
