La Nina Fizzles, Pacific Hot Blob Returns, Record Global Heat Likely to Remain


A change of three degrees [Celsius] is an “extraordinary deviation — something you would expect to happen once in a millennium.” — Richard Dewey,, on ocean warming in the northeastern Pacific


Four degrees Celsius. That’s the current deviation from the 1981 to 2010 average for sea-surface temperatures over a broad region of the northeastern Pacific, a deviation you typically wouldn’t see once in a thousand years.

During 2013 to 2015 a similar warm-up over this same region of water occurred. Such extreme heat at the ocean surface generated mass loss of sea life. Numerous species from plankton to krill to copepods to starfish and many more on up the food chain were impacted. This great ocean warming also sparked losses of ocean oxygen off Oregon and Washington, pushing waters there into low-oxygen and anoxic states. These states, though they do not support advanced ocean life, tend to…
