Maybe trace amounts of atmospheric CO2 don't kill salmon?

The Coaster: News | Salmon returns up in 2008

What a difference a year can make.

While salmon rivers everywhere in the world saw all time lows in salmon returns in 2007, the opposite is true in 2008, as rivers are seeing increased salmon returns. "Salmon returns are really up in 2008 and they're up on all the Department of Fisheries and Oceans (DFO) monitored rivers in Newfoundland and Labrador with some rivers showing an amazing increase in the number of returning salmon," said Don Ivany, the regional director for Newfoundland and Labrador for the Atlantic Salmon Federation (ASF). "Up to Aug. 10, 2008, for example, the Exploits River, which is on pace for a record year, had a return of 33,591 salmon. The average return on this river from 2003 to 2007 was 26,229 salmon. The average return on the river from 1984 to 1991 was 9,552 fish."
