Washington leading on ocean acidificationNovember 29th, 2012 by cdunagan
Ocean acidification is hitting Washington’s shellfish industry even before we begin to experience the full effects of climate change, and Gov. Chris Gregoire placed this state in the forefront of action Tuesday when she signed an executive order on the issue.
The order supports the findings of the governor’s Blue Ribbon Panel on Ocean Acidification. Check out the story I wrote for yesterday’s Kitsap Sun.
The panel released the report during an hour-long presentation of the findings. If you have time, I recommend watching the informative presentation, provided by TVW in the player at right.
The executive summary of the report, as well as the full report, its appendices and the governor’s order, can be downloaded from panel’s webpage on the Washington Department of Ecology website.
Gregoire’s order is considered the first state-level action on ocean acidification — and that has attracted attention from across the country. For example, stories were written by environmental reporter Juliet Eilperin of the Washington Post and by Virginia Gewin of Nature magazine.
Ocean acidification has been called the “evil twin” of global warming, because the effects can be more swift and more severe than gradual warming of the Earth. That’s not to discount other serious effects of climate change, including increased frequency of severe storms, sea level rise with increasing flooding, and heat waves with crippling effects on agriculture. But acidification affects organisms at the base of the entire food web.
The effects of ocean acidification will not be reversed for a long, long time, even if greenhouse gas emissions are brought under control. The upwelling of old water along the coast brings this problem right to our doorstep now and for the foreseeable future.
The shift from coal to natural gas, along with the downturn in the economy, has significantly reduced emissions of carbon dioxide in this country the past couple years, but the levels of atmospheric greenhouse gases continue to go up.
“Climate change is taking place before our eyes and will continue to do so as a result of the concentrations of greenhouse gases in the atmosphere, which have risen constantly and again reached new records,” said Michel Jarraud, secretary-general for the World Meteorological Association, in a press release issued yesterday.
The WMA reported that the years 2001–2011 were all among the warmest on record, and it appears that 2012 will continue the trend, despite a cooling influence from La Niña early this year.
“Naturally occurring climate variability due to phenomena such as El Niño and La Niña impact on temperatures and precipitation on a seasonal to annual scale,” Jarraud said. “But they do not alter the underlying long-term trend of rising temperatures due to climate change as a result of human activities.
“The extent of Arctic sea ice reached a new record low. The alarming rate of its melt this year highlighted the far-reaching changes taking place on Earth’s oceans and biosphere,” he added.
Environmental correspondent Alister Doyle reported today for Reuters that the United Nations Panel on Climate Change now believes that it is more certain than ever that humans are the primary cause of global warming.
In its 2007 report, the panel pegged the certainty at more than 90 percent. Now, it appears likely that the scientists will increase that certainty in the next report in 2013, said Rajendra Pachauri, head of the panel who spoke with Doyle at a climate conference in Qatar.
“We certainly have a substantial amount of information available by which I hope we can narrow the gaps, increase the level of certainty of our findings,” he said, adding that analyses also will increase the predicted rate of sea-level rise.
Meanwhile, the “Draft National Ocean Policy and Implementation Plan” is still undergoing review by the National Ocean Council. The report contains a chapter called “Resiliency and Adaptation to Climate Change and Ocean Acidification” (PDF 732 kb). That chapter contains some of the same recommendations offered by Washington state’s Blue Ribbon Panel, but the state plan is more specific and comes with a recommended $3.3 million budget to begin work on the problem.
U.S. Rep. Doc Hastings of Washington, chairman of the House Natural Resources Committee, is attempting to derail the plan, saying it creates an unnecessary bureaucracy and asserts federal controls not approved by Congress. Read the news release about House action against the plan.
I have not talked to anyone on the council lately, but it appears that President Obama’s election campaign over the past year effectively derailed any movement on this issue. In his first press conference after the election, he pledged to jump-start the climate-change effort, but no mention was made of the ocean policy. Review the video below at 42:20.
