RECOMMENDED IMAGE(S): Dust over Eastern Australia

A large dust storm engulfed eastern Australia on Wednesday, September 23rd. The massive storm “clogged the skies over Sydney . . . diverting international flights, disrupting ferries and prompting a spike in emergency calls from people suffering breathing difficulties.” More amazing images can be found at The Big Picture. From the Christian Science Monitor:

According to Reuters, the storm carried an estimated 5 million tons of dust from the continent’s interior to the east coast. A fair bit of that is priceless farm topsoil, according to the report. At one point, the storm was dumping an estimated 75,000 tons an hour into the Pacific off Sydney.

The country’s eastern portion, particularly the farmland watered (at least at one time) by the Murray and Darling Rivers, is in its 12th year of severe drought. And forecasters say that it is likely to continue as El Nino strengthens through the rest of the year.

As for the virtually inevitable global-warming question: Researchers and forecasters are loathe to attribute any single storm to climate change. But the storm does represent one kind of weather phenomenon that is expected to become more frequent as the climate warms.

Once it’s kicked up, the dust itself has effects on regional and local climate. The particles reflect sunlight back into space, cooling temperatures underneath it somewhat. Scientists at NASA’s Goddard Space Flight Center in Greenbelt, Md., published a study two years ago suggesting that dust-triggered cooling over the North Africa and the eastern Atlantic can affect sea-level air pressure and temperatures thousands of miles away. Others have noted that North African dust storms can retard hurricane formation in the Atlantic because its parasol effect keeps the ocean surface cooler than it might otherwise be.

EVOLUTION: Kirk Cameron irrationally links Charles Darwin to Hitler in altered version of Charles Darwin’s Origin of Species

In addition to ignorance, Kirk Cameron is clearly guilty of misrepresentation. As an evangelical “Christian,” I guess that makes him a hypocrite.

And he’s called out for distorting or spinning the facts:

***

There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

CLIMATE CHANGE: Second Circuit Court of Appeals decision in Connecticut v. American Electric Power Company “game-changing”

The Second Circuit announced an important decision today that allowed several states and land trusts to continue their nuisance claim against various U.S. utilities over their release of carbon dioxide emissions, which contribute to climate change. From Reuters:

A U.S. Appeals Court reinstated on Monday a 2004 lawsuit by eight states and the city of New York against five of the largest U.S. utilities over their carbon dioxide emissions.

The lawsuit was dismissed in October 2005 by U.S. District Court Judge Loretta Preska, who said the issue was a political question for Congress or the President, not the judiciary.

Monday’s ruling by the U.S. Court of Appeals for the 2nd Circuit in New York said the judge “erred in dismissing two complaints on the ground that they presented non-justiciable political questions.”

The lawsuit against American Electric Power Co Inc, Southern Co, Xcel Energy Inc, Cinergy Corp and the Tennessee Valley Authority public power system, argued that greenhouse gas emissions from their plants were a public nuisance and would cause irreparable harm to property.

The utilities are five of the largest carbon dioxide emitters in the United States. Around 40 percent of U.S. carbon dioxide emissions come from fossil-fueled power plants.

The plaintiffs aren’t seeking money damages but injunctive relief. More on the plaintiff’s claims from Courthouse News Service:

Carbon dioxide acts as a greenhouse gas that traps heat in the earth’s atmosphere, causing the earth’s temperature to rise, the plaintiffs claimed. They asked the court to force the power companies to cap and then decrease emissions, warning that the earth’s temperature “will accelerate over the coming decades unless action is taken to reduce emissions of carbon dioxide.”

They filed suit under federal nuisance law or, alternatively, state nuisance law. The district court dismissed their actions as barred by the political question doctrine, explaining that the issue of global warming is best left to the political branches of government to resolve.

The plaintiffs launched a multipronged appeal, claiming that their cases aren’t barred by the political question doctrine; they have standing to sue; their federal nuisance claim was properly pleaded; and the Clean Air Act doesn’t displace that claim.

The power companies argued the opposite on each of these points and urged the Manhattan-based appeals court to back the lower court’s decision.

In a 139-page opinion, the court found that all of the plaintiffs have standing to challenge the alleged contributions to global warming, which the court characterized as “interference with a public right in protecting natural resources.”

And although the Clean Air Act addresses pollution and global climate change, the court ruled, the Environmental Protection Agency “does not currently regulate carbon dioxide under the (Act) – at least not in the sense that EPA requires control of such emissions at this time.” In other words, the EPA has only proposed regulation; it hasn’t imposed it.

Without specific regulation, the Clean Air Act and other federal laws “touching on” global warming don’t prevent the plaintiffs from suing under federal nuisance laws, the court concluded.

The judges also rejected the power companies’ claim that the lawsuit would undermine the nation’s global climate-change strategy. This claim “simply reiterates their political question argument and must be rejected for similar reasons,” Judge Hall wrote.

Finally, the court determined that the Tennessee Valley Authority isn’t immune from suit based on its status as a federally chartered agency.

“The flaw in TVA’s … argument is that TVA is not the United States or Congress,” Hall wrote, noting that the TVA has sided against the government “in a number of cases.”

The Second Circuit stressed that they’re not being asked to solve the problem of global warming where government has failed. From The Australian:

“A decision by a single federal court concerning a common law of nuisance cause of action, brought by domestic plaintiffs against domestic companies, does not establish a national or international emissions policy,” US Circuit Judge Peter W. Hall wrote.

“Nor could a court set across-the-board domestic emissions standards or require any unilateral, mandatory emissions reductions over entities not party to the suit.”

The cases were seeking to limit and ultimately reduce carbon emissions at six domestic coal-fired electricity plants, rather than ask the court to “fashion a comprehensive and far-reaching solution to global climate change,” Judge Hall wrote.

US District Judge Loretta Preska in Manhattan dismissed the cases in 2005, saying the question of whether carbon-dioxide emissions should be reduced laid with Congress, not the courts.

.       .       .

Connecticut Attorney General Richard Blumenthal said: “This ruling restoring our legal action breathes new life into our fight against greenhouse gas polluters and changes the legal landscape to impose responsibility where it belongs.

“Our legal fight is against power companies that emit a huge share of our nation’s CO2 contamination, but it will set a precedent for all who threaten our planet with such pernicious pollution.”

New York Attorney General Andrew Cuomo said, “This is a game-changing decision for New York and other states, reaffirming our right to take direct action against global warming pollution from power plants.

“Today’s decision allows us to press this crucial case forward and address the dangers posed by these coal-burning power plants. My office will continue to be a leader in the fight to tackle the risks global warming poses to our environment, public health and economy.”

The cases were remanded to Judge Preska for further proceedings.

New US Supreme Court Justice Sonia Sotomayor was on the three-judge panel that heard arguments in the case in 2006. However, Justice Sotomayor wasn’t involved in the decision as a result of her elevation to the high court.

Representatives at AEP, Southern, Xcel and Duke said employees at their companies were still reviewing the decision and wouldn’t comment until they had had a chance to read the entire 139-page document.

A TVA spokeswoman said TVA had just received the decision and will review it in its entirety.

Another global warming case is a much watch. In Native Village of Kivalina v. Exxon Mobil, et al., a nusiance action was brought by an Alaskan village against oil companies. The villagers are seeking monitary damages.  According to Wikipedia, Native Village of Kivalina v. Exxon Mobil is “the first is to recover ‘monetary damages for defendants’ past and ongoing contributions to global warming’; the second, to recover ‘damages caused by certain defendants’ acts in furthering a conspiracy to suppress the awareness of the link between these emissions and global warming.’” More from National Underwriter Property And Casualty Insurance News:

Still, the Anderson Kill panel noted that one case worth watching is Native Village of Kivalina v. Exxon Mobil, et al., in which an Inuit village in Alaska has brought a nuisance suit in February 2008 against major oil companies.

The plaintiffs are seeking joint and several liability for nuisance and civil conspiracy, claiming that the oil companies’ contribution to global warming has caused melting ice which will lead to the eventual flooding of their village.

The case was brought in California. John Nevius, a shareholder in the New York office of Anderson Kill, said a motion to dismiss was filed in June 2008 in Virginia. He said the insurance company defending the suit has cited the pollution exclusion in its motion.

OCEAN ACIDIFICATION S.O.S

Image by Lou Dematteis/Spectral Q/Handout via The Huffington Post
Acid Oceans SOS

The ocean is a natural carbon sink: In addition to biotic carbon sequestration, the ocean naturally absorbs CO2. Consequently, when we burn fossil fuels, we release carbon that has been trapped for millions of years, and this excess carbon enters the Earth’s carbon cycle.

This anthropogenically-released excess carbon is what causes ocean acidification, and the oceans have become increasingly more acidic since the industrial revolution. More on this from Physorg.com:

The chemistry is very straight-forward: ocean acidification is linearly related to the amount of CO2 we produce. CO2 dissolves in the ocean, reacts with seawater and decreases the pH. Since the industrial revolution, the oceans have become 30 percent more acidic (from 8.2 pH to 8.1 pH). “Under a “business as usual scenario, predictions for the end of the century are that we will lower the surface ocean pH by 0.4 pH units, which means that the surface oceans will become 150 percent more acidic – and this is a ‘hell of a lot’ “, said Jelle Bijma, chair of the EuroCLIMATE programme Scientific Committee and a biogeochemist at the Alfred-Wegener-Institute Bremerhaven.

Obviously, the impacts on calcifying organisms are worrying, because as oceans become more acidic, there is a “reduction in availability of the calcium carbonate needed for calcified shells and plates.” Examples of calcifying organisms include bivalves, corals, and some plankton. Since calcifying organisms are important in maintaining ocean ecosystems, various stakeholders are concerned about the impacts of ocean acidification. The negative impacts on calcifying organisms have fishers worried about their livelihoods and recreational users of oceans, such as kayakers, are concerned about aesthetic impacts. As a result, to raise awareness, these stakeholders literally spelled out an S.O.S. on ocean acidification. More from Alaskajournal.com:

Commercial fishermen, recreational boaters and kayakers took to the waters of Kachemak Bay in Homer during the Labor Day weekend to spell out an SOS on ocean acidification and to ask the world’s help in saving ocean ecosystems.

Under warm and sunny skies, interspersed at times by fog, more than 100 fishing boats, sail boats, skiffs and kayaks positioned themselves on the bay to spell out “Ocean Acid SOS.”

.       .       .

“A lot of people have heard about climate change,” said Bob Shavelson, executive director of Cook Inlet Keeper, a nonprofit group dedicated to protecting the Cook Inlet watershed. “Few have heard about ocean acidification.”

Ocean acidification is caused by the excess carbon dioxide that has been released into the atmosphere since the industrial revolution, said Jeremy Mathis, a chemical oceanographer with the University of Alaska Fairbanks. The more the carbon dioxide is absorbed into the ocean, the more acidic the ocean becomes.

Mathis is one of a growing number of scientists speaking out on the dangers of ocean acidification to the ocean ecosystems. Research results released Aug. 11 by Mathis indicated that Alaska’s oceans are becoming increasingly acidic, and that could damage Alaska’s king crab and salmon fisheries. The results also matched his recent findings in the Chukchi and Bering seas.

Northern coastal oceans, such as those off Alaska, may be becoming more acidic than other oceans, and at a faster rate. Mathis said that the cold waters and broad, shallow continental shelves around Alaska’s coast could be accelerating the process of ocean acidification in the North.

Frigid waters can absorb more carbon dioxide, he said. The shallow waters of Alaska’s continental shelves also retain more carbon dioxide because there is less mixing of seawater from deeper ocean waters.

More on ocean acidification from NOAA:

The global oceans are the largest natural reservoir for carbon dioxide, and absorb approximately 30-50% of global anthropogenic CO2 emissions. In the future, increased CO2 uptake by the oceans is expected to reduce surface ocean pH by 0.3-0.5 units over the next century (Feely et al., 2004).

As carbon dioxide (CO2) reacts with seawater, fundamental chemical changes occur that cause a reduction in seawater pH (or acidification) and reduces the availability of chemical compounds which play an important role in shell creation for a number of marine organisms. Ocean acidification impacts the ability of marine calcifiers, such as corals and mollusks, to make shells and skeletons from calcium carbonate. This is due to a reduction in the availability of the chemical constituents needed for calcified shells and plates. As a result, ocean acidification could affect some of the most fundamental biological and geochemical processes of the sea in coming decades and be disruptive to the marine food web. Estimates of economic losses from coral reef degradation in the Caribbean alone range from $350-870 million/year by 2015 to coastal countries which currently receive annual economic benefits from fisheries, dive tourism, and shoreline protection services valued collectively at $3-4 billion/year (Burke and Maidens, 2004).

Data collected from ocean sampling in the Pacific Ocean from the southern to northern hemispheres confirms that the oceans are becoming more acidic, according to NOAA’s Pacific Marine Environmental Laboratory (PMEL). A recently completed field study from Tahiti to Alaska collecting data about the effects of ocean acidification on the water chemistry and marine organisms found evidence that verifies earlier computer model projections. These findings are consistent with data from previous field studies conducted in other oceans.
