NOAA: Ocean Acidification Rises, Shells Shrink

NOAA: Ocean Acidification Rises, Shells Shrink | Garry Rogers | Scoop.it

"The oceans act as a “carbon sink,” absorbing vast amounts of carbon dioxide. Acidification occurs when amounts of carbon dioxide are dissolved into seawater, where it forms carbolic acid.

Scientists say the oceans are now 30 percent more acidic than they were at the beginning of the industrial revolution about 250 years ago.

Among the sea species most vulnerable to acidification are shellfish, because a build-up of acid in waters prevents species developing their calcium shells. Alaska’s salmon stocks are also at risk as one of the main ingredients of a salmon diet are pteropods, small shell creatures."

Garry Rogers's insight:

Greenhouse gas (mainly CO2) buildup in the atmosphere has a spreading web of consequences. The tentacles of the web are spreading quickly, too quickly for species to adapt.  The human impact is more like a massive meteorite strike than the ice-age climate changes or the slower continental drift changes.
