From the San Diego Union-Tribune:

“New research by a scientist in San Diego shows that some of Southern California's most abundant marine fish are spawning earlier than they did 60 years ago, possibly signaling a shift in ocean health.

Researchers are unsure why, but they suspect it's because the water is getting warmer. Ocean temperatures off the Southern California coast have risen 1.3 degrees Celsius between 1949 and 2000, Asch said. Two degrees C over the baseline level is considered by experts to be the tipping point of concern for certain ecosystems. The effects are more significant in warmer ecosystems than colder ones. … “

The implications for marine ecosystems are not yet clear, but on the terrestrial side researchers think these sorts of changes are contributing to the unraveling of natural communities.
