Even though the debate on the causes of man-made global warming is not over, Harvard geoscientists have an idea on how to slow it down.
The researchers want to suck out naturally-occurring acid from the oceans by putting treatment plants near coastlines. They say the less acidic the oceans are, the more they can absorb carbon, which some climate researchers say is partially responsible for global warming. This technique may have some negative side effects since the scientists say 100 facilities similar to large sewage treatment plants would be necessary to complete the project.
