"The world's already overtaxed fisheries are being stressed to their limits by climate change, putting at risk a critical component of the world's diet. As temperatures rise, fish populations are projected to plummet and disappear in some regions, especially in the tropics."

"The salmon farms in the far south of Australia, where icy winds roar in from Antarctica, seem an unlikely casualty of global warming."

"Climate change is already causing staggering impacts on the oceans and ice-filled regions that encompass 80 percent of the Earth, and future damage from rising seas and melting glaciers is now all but certain, according to a sobering new report from the United Nations."

"Americans eat an average of 16 pounds of fish each year, and that number is growing. But how to meet our demand for fish is a controversial question, one that is entering a new chapter as the Environmental Protection Agency seeks to approve the nation's only aquaculture pen in federal waters."

"Warming waters and a series of dams are making the grueling migration of the Chinook salmon even more deadly — and threatening dozens of other species."

"This past summer, high water temperatures contributed to the deaths of more than 100,000 salmon."

"A massive marine heat wave that caused record warming of ocean waters off the West Coast five years ago, sending salmon numbers crashing and malnourished sea lions washing up on beaches across California and other Pacific states, is back, scientists said Thursday."
