Stephen Jay Gould (1941-2002)

Stephen Jay Gould is among the best known and widely read scientists of our present generation. A paleontologist by strict profession, Gould is perhaps better recognized for his contributions to evolutionary theory and the philosophy and history of science. He currently holds the position of Alexander Agassiz Professor of Zoology, and Professor of Geology at Harvard University, and is also curator for Invertebrate Paleontology at Harvard’s Museum of Comparative Zoology.

The author of 300 consecutive essays for his monthly column “This View of Life” in Natural History magazine, Gould has also penned over 20 best-selling books, and has written nearly a thousand scientific papers. In addition, he has received numerous awards including the MacArthur Foundation Prize Fellowship, the prestigious Medal of Edinburgh, and the Silver National Medalm of the Zoology Society of London.

Climate Change: Vital Signs of the Planet: Big coastal cities sink faster than seas rise

While the threat of rising seas is well established, a phenomenon that is, in a sense, its opposite receives far fewer headlines: large coastal cities sinking faster than oceans can rise.

That is the conclusion of a review article published by a team of scientists who recently assembled in New Orleans, La., and in Venice, Italy, to examine the problem. Extraction of groundwater or fossil fuels, and sometimes simply generations of farming, are causing large metropolitan areas in coastal zones around the world to subside surprisingly quickly—making the relative rise of adjacent seas an even greater potential hazard.

“Sea level rise is a problem, and subsidence is a huge problem, too,” said Cathleen Jones, a researcher at NASA’s Jet Propulsion Laboratory in Pasadena who specializes in such hazards and is a member of the New Orleans team.

“There are areas where it is happening more rapidly than sea level rise,” she said. “I think it is not fully appreciated how much greater subsidence is in some of these areas, and how much it contributes to the loss of wetlands.”

Rapid subsidence makes many of these areas more vulnerable to the effects of climate change, especially those at elevations less than 10 meters (33 feet) above sea level. Several of these qualify as “megacities,” with populations greater than 10 million.

The most threatened: large river deltas, home to an estimated 500 million people. The fastest subsidence rate, 250 millimeters or nearly 10 inches per year, was seen in China’s Huanghe Delta. Southeast Asia saw 30 to 60 millimeters (1.2 to 2.4 inches) per year, while Katrina-ravaged portions of New Orleans saw rates as high as 35 millimeters (1.4 inches) per year.

Climate Change: Vital Signs of the Planet: Short-lived greenhouse gases cause centuries of sea-level rise

Researchers report that warming from short-lived compounds — greenhouse gases such as methane and chlorofluorocarbons, that linger in the atmosphere for just a year to a few decades — can cause sea levels to rise for hundreds of years after the pollutants have been cleared from the atmosphere.

Even if there comes a day when the world completely stops emitting greenhouse gases into the atmosphere, coastal regions and island nations will continue to experience rising sea levels for centuries afterward, according to a new study by researchers at MIT and Simon Fraser University.

In a paper published this week in the Proceedings of the National Academy of Sciences, the researchers report that warming from short-lived compounds — greenhouse gases such as methane, chlorofluorocarbons, or hydrofluorocarbons, that linger in the atmosphere for just a year to a few decades — can cause sea levels to rise for hundreds of years after the pollutants have been cleared from the atmosphere.

“If you think of countries like Tuvalu, which are barely above sea level, the question that is looming is how much we can emit before they are doomed. Are they already slated to go under, even if we stopped emitting everything tomorrow?” says co-author Susan Solomon, the Ellen Swallow Richards Professor of Atmospheric Chemistry and Climate Science at MIT. “It’s all the more reason why it’s important to understand how long climate changes will last, and how much more sea-level rise is already locked in.”
