Smolt-To-Adult returns. SARs. The BENCHMARK of Columbia/Snake River basin salmon and steelhead recovery. And in recent years the SARs benchmark – tagged, tracked fish-- is screaming bad news for Snake River salmon and steelhead. Bringing these fish back from the brink as the regional climate warms requires urgency.
The global abundance of salmon in the Pacific Ocean in 2020 based on commercial catch was the lowest since 1982 and in North America the catch was the lowest since 1977, despite a record number of hatchery releases the year before, according to a report released in May 2021 by the North Pacific Anadromous Fish Commission of Vancouver B.C.
The Canadian government last week announced a $647 million strategy to save Pacific salmon, aiming to stop the declines now while helping rebuild populations over the longer term.
Earth's climate is determined by a delicate balance between how much of the Sun's radiative energy is absorbed in the atmosphere and at the surface and how much thermal infrared radiation Earth emits to space. A positive energy imbalance means the Earth system is gaining energy, causing the planet to heat up. Now, NOAA and NASA researchers have found that Earth’s energy imbalance approximately doubled during the 14-year period from 2005 to 2019.
Scientists and local restoration communities are now seeking new ways to implement habitat restoration so that Northern California rivers and streams can support healthy salmon and steelhead populations again. Hence, SHaRP, Salmonid Habitat Restoration Priorities.
Is the availability of water to meet all instream (flows for fish) and out-of-stream demands vulnerable to expected changes in climate and population growth in eastern Washington?
After being put on hold during the four years of the Trump Administration, the Environmental Protection Agency is relaunching its Climate Change Indicators in the United States website for the public.
From the Pacific Northwest to the Rocky Mountains, summers in the West are marked by wildfires and smoke. New research from the University of Utah ties the worsening trend of extreme poor air quality events in Western regions to wildfire activity, with growing trends of smoke impacting air quality clear into September.
NOAA will soon release a much-anticipated update of U.S. climate data for placing recent weather conditions—such as heat waves and flooding rain—into historical context.
