Acidification of Oceans Caused by Climate Change to Last Tens of Thousands of Years

Friday, May 10, 2013

Scientists working in the Arctic warn that the increase of carbon dioxide (CO2) in the atmosphere is not only warming the planet—it is also impacting the acidity of the ocean.


Members of the Arctic Monitoring and Assessment Programme say climate change has already raised ocean acidification, which would take tens of thousands of years for nature to reverse even if CO2 levels could be stemmed immediately.


As it stands, the average acidity of surface ocean waters is now about 30% higher than before the Industrial Revolution, experts estimate.


The increase in acidity could affect many ocean species, including commercially important fish, scientists say. They also predict major changes in the marine ecosystem in the years ahead, with some species being harmed, while others thrive.


Absorption of CO2 by the ocean is particularly acute in the freezing waters of the Arctic, where the summer melting of surface ice has exposed more of the sea to atmospheric CO2.

Climate blame copy and paste reporting has done to journalism what naughty priests did for religion. You fear mongered us through 28 years of needless panic to billions of helpless children. Former Climate Blame Believers are Better Planet Lovers Science can say asteroid hits are real but won't say their CO2 climate crisis is as real as an asteroid hit is. It's been 28 years of a "maybe" crisis and science has never said any crisis "WILL" happen. Not one IPCC warning isn't smothered in "maybes". 28 years of "maybe" a crisis proves it "won't be" a crisis. Occupywallstreet now does not even mention CO2 in its list of demands because of the bank-funded and corporate run carbon trading stock markets ruled by politicians and the CO2 exaggeration is doomed to be Liberalism's Iraq War, another war without an real enemy. Who's the fear mongering neocon now?
