coral reefs

Corals, lobsters, and many other ocean creatures are unlikely to withstand the increasing acidity of the oceans brought on by global warming, according to a new report from Oceana.

Our new report, "Acid Test," examines the far-reaching consequences of the accumulation of heat-trapping gases, particularly carbon dioxide, in the world's oceans.

High levels of carbon dioxide (CO2) in seawater deplete the carbonate that marine animals need for their shells and skeletons. Creatures that are at risk if trends continue include corals, commercial fish, including shrimp and lobster; and pteropods, or swimming sea snails, which are an important part of the base of polar and sub-polar food chains.

We are calling for a reduction of CO2 emissions in industrialized countries by 25 to 40 percent below 1990 levels by 2020.

The key findings of the report include:

Until recently, models analyzing the effects of global warming on coral bleaching have been strictly based upon thermal stress projections, but a new study highlights the added impact of ocean acidification, yielding startling results.

Through experimental research, Dr. Ken Anthony led a team of scientists who found that the productivity and calcification rates of corals and important coral reef builders, crustose coralline algae, significantly decline under higher temperatures coupled with increased CO2 and high light exposure, suggesting that high CO2 levels may exacerbate coral bleaching events in warmer waters.

The answer, according to our new report, is an overwhelming yes.

As you may have heard on NPR's Marketplace this morning, our report, Sea the Value: Quantifying the Value of Marine Life to Divers, asked scuba divers whether they would be willing to pay to help protect populations of ocean wildlife -- and a majority of divers surveyed said they would.

Before I review the good news this week, I have to review the not-so-good. Today the Washington Post reports:

"The Bush administration has decided not to take any new steps to regulate greenhouse gas emissions before the president leaves office, despite pressure from the Supreme Court and broad accord among senior federal officials that new regulation is appropriate now."

To continue the coral reef theme of my earlier post, the AP published a story yesterday about a NOAA report docum
