Ocean Acidification and San Diego
This week the New Yorker’s Elizabeth Kolbert continues her groundbreaking analysis of global climate change with a look at how human related carbon emissions are turning the ocean acidic in “The Darkening Sea: What Carbon emissions are doing to the ocean.” Kolbert’s original work in The New Yorker is spelled out in her book, Field Notes from a Catastrophe. The article is an excellent summary of the reams of scientific research that has been published widely. Kolbert’s article should be required reading for anyone who believes that San Diego’s coast will be or has been immune from the impacts of climate change and that a small population of harbor seals represents a significant threat to our coastline.
Some of Kolbert’s observations include the following:
- “The concentration of carbon dioxide in the aid today—three hundred and eight parts per million—is higher than it has been at any point inn the past six hundred and fifty thousand years, and probably much longer.
- “At the current rate of emissions growth, carbon dioxide concentration will top five hundred parts per million—roughly double pre-industrial levels—by the middle of this century.”
- Increases in carbon dioxide levels “will produce an eventual global temperature rise of between three and half and seven degrees Fahrenheit, and that this in turn, will prompt a string of disasters, including fiercer hurricanes…and the inundation of many of the world’s major coastal cities.”
- “Already, humans have pumped enough carbon into the oceans—some hundred and twenty billion tons—to produce a .1 decline in surface pH…a .1 drop represents a rise in acidity of about thirty percent.”
- “Because of the slow pace of deep-ocean circulation and the long life of carbon dioxide in the atmosphere, it is impossible to reverse the acidification that has taken place.”
Kolbert, as did Ken Weiss did in his brilliant Alerted Oceans series in the Los Angeles Times, argues that this drop in pH levels will give way to an increase in ocean slime and jellyfish that will occupy ecological niches now filled by, well, fish and the rest of the ocean food chain.
The irony here, is that while Jerry Sanders, Scott Peters and the Stepford Wife public servants at the City’s Recreation Department squander public monies on dredging projects for Children’s Pool, continue to defend the bizarre rope barrier at La Jolla Shores, and oversee San Diego’s wasteful kelp eradication program, Mother Ocean will soon be taking its revenge on San Diego. The years of defending the dumping millions of gallons of sewage into the ocean, failure to clean up Mission Bay, criminal contempt for warnings about the antiquated sewage treatment system, spending millions on sand replenishment projects, and ignoring the corruption of the Bajagua project’s blocking efforts to reduce border pollution, are now coming home to roost.
If a small population of harbor seals freaks out the anti-seal brigade in La Jolla, imagine the response to beaches filled with slime and jelly fish. It is rumored that Jerry Sanders, like President Bush believes that global climate change is a hoax. Sorry, Jerry. Let’s see you finally, for once, take some leadership on the issue that will matter most to the future of San Diego.
I respect your work,it is the most nice one i ever see
