How climate change effects ocean life
Warming ocean
temperatures could eliminate much, if
not all, marine habitat for Pacific sockeye salmon, and probably other salmon
as well. Sockeyes are extremely temperature-sensitive: their metabolism
increases in warmer water, requiring larger amounts of food.
Coral reefs, the most
biologically diverse and beautiful marine ecosystems, are also at extreme risk.
The upper heat tolerance for many reef
corals is just a few degrees above normal temperatures. Any warmer, the reefs
begin to bleach and die. Large numbers of corals are turning completely white
and dying, with over 90 percent mortality in parts of the Indian Ocean.
Polar
Regions suffer worse biological impacts than lower latitudes. Sea ice is
diminishing in both the Arctic and Antarctic, depriving wildlife of hunting and
breeding grounds.
