A new study out in Nature finds that human-emitted aerosols may be largely to blame for the Atlantic Multidecadal Oscillation–and therefore that this apparently cyclical climate phenomenon may be neither multidecadal nor an oscillation. Read a perspective on this article here.
Senators Maria Cantwell (WA) and Mark Begich (AK) spoke last week at the Seattle Aquarium about the importance of being prepared to deal with tsunami debris that may land on the west coast. Oceanography Professor Parker MacCready attended the event, and his lab’s oceanographic models are helping inform what may become of some of the debris. Read more here.
The Premier of British Columbia and the governors of Oregon, Washington and California have announced that they will collaborate to manage potential marine debris from the March 2011 earthquake and tsunami in Japan that may wash up along the West Coast.

According to recently published research, air pollution from Asian countries increase the ozone levels in US cities, sometimes past EPA-specified limits for safety. UW’s Dan Jaffe is quoted. Read more here.
A new project led by researchers in the UW School of Public Health will assess key health issues affecting people who use the Duwamish River or live nearby. Findings from the assessment will be provided to the U.S. Environmental Protection Agency to help inform their selection of a cleanup plan for the Lower Duwamish Waterway, which was designated a Superfund site in 2001.

According to a report by the Environmental Protection Agency, facilities in the three northwest states released 105 million pounds of toxic chemicals into the air, land, and water in 2010. This contributed to the reversal over the past year in the national trend: there was an increase in such releases after two years of decreases. Read more here.
New research from UW-Bothell shows that the upper atmosphere is working as a chemical reactor that transforms elemental mercury into oxidized mercury, which makes it more able to be deposited in aquatic ecosystems and, eventually, to enter the food chain. Read more here.
