Caption by Holli Riebeek and Adam Voiland9 November 2010 Of all the pollution that fills our lungs on any given day, the most dangerous is the small stuff.

From 1950 to 2008, most land areas have warmed up by 1–3°C, with the largest warming over northern Asia and northern North America. During the same period, precipitation decreased over most of Africa, southern Europe, South and East Asia, eastern Australia, Central America, central Pacific coasts of North America, and some parts of South America.

Those job […]
Between 1979 and 2008, first-year sea ice in the summer has been declining at a rate of 8.7% per decade, whereas the thick multi-year sea ice in the summer is being lost at an average rate of 6.4% per decade and over 20% per decade in some areas of the Canadian Arctic Archipelago. This decreasing […]
(A) Annual releases of juvenile hatchery chum salmon, pink salmon, and sockeye salmon into the North Pacific Ocean and (B) the proportion of total hatchery releases originating from North American hatcheries, 1950–2005. Values exclude spawning-channel sockeye salmon. Values are updated from Mahnken, et al. (1998). Ruggerone, et al, 2010 Gregory T. Ruggerone, Randall M. Peterman, […]
The number of salmon in the Pacific Ocean is twice what it was 50 years ago. But there is a downside to this bounty, as growing numbers of hatchery-produced salmon are flooding the Pacific and making it hard for threatened wild salmon species to find enough food to survive.
