Ocean Acidification: What is It, and Which Communities are at Risk?

January 28, 2014 by NRDC Switchboard

Ocean Acidification and Risk

Chad Coffin, president of the Maine Clammers Association, worries about Maine’s mudflats. That’s because in some areas these low-lying coastal wetlands have become acidic enough to kill young clams before they reach maturity.[read more]

Beyond Shellfish, Ocean Acidification is Bad for People

December 7, 2013 by NRDC Switchboard

There's a predictable arc to many environmental debates. Step 1: Scientists observe a change in the natural world due to human activity. Step 2: A discussion ensues about what this change might mean for the natural world. Step 3: What does this observed change mean for people?[read more]

Acidification: The Ocean's Changing Climate

October 17, 2013 by Jessica Kennedy

A chemical change is taking place in our oceans, and it is making waters more and more acidic. Ocean acidification occurs due to several effects of CO2 in the atmosphere. Excess amounts of CO2 are entering our oceans and creating a high concentration of carbonic acid.[read more]

Kelp Forests Thrive in California's Underwater Parks

Kelp and Acidification

We need to continue to build resiliency in our ocean environments so we can better withstand the changes that are already taking place. California has protected a full 16 percent of its coastal waters, putting the state in the vanguard of global ocean protection.[read more]

IPCC Report Underscores Need to Address Ocean Acidification

October 6, 2013 by NRDC Switchboard

Ocean Acidification and the IPCC Report

The recent IPCC report addressed an impact of rising atmospheric CO2 emissions: ocean acidification. While national and international media outlets largely skipped the report’s findings on acidification, my eyes went straight to what we call climate change’s “evil twin.”[read more]

Ocean Acidification May Amplify Global Warming Up To 0.9°F

August 28, 2013 by Joseph Romm

Ocean Acidification

Ocean acidification may speed up total warming this century as much as 0.9°F, a new study finds. This amplifying feedback is not to be found in the IPCC climate report — one more reason it provides an instantly out of date lowball estimate of future warming.[read more]

Climate Change: Arctic Ocean Rapidly Acidifying

May 23, 2013 by Tom Schueneman

Arctic Ocean acidification

After three years of ongoing research by an international team of scientists, a study commissioned for a first-ever comprehensive assessment of Arctic Ocean acidification was presented last week.[read more]

Is the 2 degree target likely to save most coral reefs?

September 21, 2012 by Simon Donner

The new paper in Nature Climate Change by Katja Frieler, a number of other colleagues and I warns that limiting global warming to 2 deg C Celsius, the threshold long-discussed at the policy level and now enshrined in the Cancun Accord, is unlikely to be enough to spare most coral reefs from climate change. The paper might look like the...[read more]

Ocean acidification and the EPA

March 12, 2010 by Lou Grinzo

Ocean acidification has been getting more attention in the last few months, but far less than is appropriate, in m opinion. After all, we’re messing with the chemistry of the waters that provide an enormous amount of food for human beings around the world, and we’re doing it by indirectly pumping tens of billions of tons of CO2 into it...[read more]

A Sea Change: Imagine a World without Fish — ocean acidification film — premiers tonight on Planet Green

September 26, 2009 by Joseph Romm

Global warming is “capable of wrecking the marine ecosystem and depriving future generations of the harvest of the seas” (see Ocean dead zones to expand, “remain for thousands of years”). A new documentary on ocean acidification is airing tonight (Saturday) on Planet Green at 8 pm.  (You can find your Planet Green channel on their...[read more]

Jane Lubchenco interview on NPR: “Ocean acidity has increased by 30%” thanks to human emissions

June 10, 2009 by Joseph Romm

Global warming is a major threat to life in the oceans — and humans who depend on that life (see Ocean dead zones to expand, “remain for thousands of years”).  As one recent study found: Global warming may create “dead zones” in the ocean that would be devoid of fish and seafood and endure for up to two millennia…. Its authors say...[read more]

Ocean Acidification Warning

October 17, 2007 by Joseph Romm

Ocean acidification from human emissions of carbon dioxide is a very serious problem, as I have noted. Now Australia’s ARC Centre of Excellence for Coral Reef Studies has issued a new warning:The world’s oceans are becoming more acid, with potentially devastating consequences for corals and the marine organisms that build reefs and...[read more]
