Our Cro-Magnon Forbears Adapted Readily to Extreme Climatic Change

In the passage that follows, Brian Fagan describes our best guess at the landscape of part of France about 18,000 years ago, and then describes how the landscape dramatically changed in a short period. (We usually do not know exactly how short—maybe as long as a few hundred years, maybe as short as a month.)

(p. xiv) There would have been black aurochs with lyre-shaped horns, perhaps arctic foxes in their brown summer fur feeding off a kill, perhaps a pride of lions resting under the trees. If you’d been patient enough, you’d have seen the occasional humans, too. But you would have known they weren’t far away–informed by the smell of burning wood, trails of white smoke from rock-shelter hearths, the cries of children at play. Then I imagined this world changing rapidly, soon becoming one of forest and water meadow, devoid of reindeer and wild horses, much of the game lurking in the trees. I marveled at the ability of our forebears to adapt so readily to such dramatic environmental changes.

Few humans have ever lived in a world of such extreme climatic and environmental change.
. . .
(p. xvi) The story of the Neanderthals and the Cro-Magnons tells us much about how our forebears adapted to climatic crisis and sudden environmental change. Like us, they faced an uncertain future, and like us, they relied on uniquely human qualities of adaptiveness, ingenuity, and opportunism to carry them through an uncertain and challenging world.

Energy Department Wastes Energy

(p. A17) WASHINGTON — Like flossing or losing weight, saving energy is easier to promise than to actually do — even if you are the Department of Energy.

Its Web site advises that choosing new lighting technologies can slash energy use by 50 to 75 percent. But the department is having trouble taking its own advice, according to an internal audit released on Wednesday; many of its offices are still installing obsolete fluorescent bulbs.
And very few have switched to the most promising technology, light-emitting diodes, which the department spent millions of dollars to help commercialize.
Many of the changes would generate savings that would pay back the investment in two years or so, according to the report, by the department’s inspector general.
In one case, the Department of Energy made most of the investment by installing timers to shut off lights at night when it moved into a new building in 1997. But it got no benefit: as of March of this year, it had not bought the central control unit needed to run the system.

Expert Says Australian Cow Burps Add to Global Warming

KlieveAtholCattleBurpExpert2010-07-23.jpg“Athol Klieve, an expert on cattle stomachs, with steers used for research on reducing methane emissions from belching cattle.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A14) GATTON, Australia — To hear Athol Klieve tell it, a key to reducing Australia’s enormous carbon emissions is to make a cow more like this country’s iconic animal — the kangaroo.
. . .
Australia contributes more greenhouse gases per capita than just about any other country, with its coal-fired power plants leading the way. But more than 10 percent of those gases come from what bureaucrats call livestock emissions — animals’ burping.
At any given point, after munching and regurgitating grass, tens of millions of Australian cattle, as well as sheep, are belching methane gases nonstop into the air. With methane considered 21 times more potent than carbon dioxide in warming the atmosphere, the burping has given ammunition to environmentalists, vegetarians and other critics of beef while initially putting the large meat industry on the defensive.
. . .
Ruminants release methane because of the peculiar way they digest their food. Inside a cow’s foregut, which can contain more than 200 pounds of grass at any given time, fermentation of the food leads to the release of hydrogen, a byproduct that would slow down the fermentation. Microbes known as methanogens help the ruminants get rid of the excess hydrogen by producing methane gases that the animals release into the atmosphere.
In other animals known as hindgut fermenters, including humans — in which food is fermented after going through their stomachs — methane is sometimes released through flatulence, a fact that, Mr. Klieve said, has led to misunderstanding about his work
“We’ve had to put up with that all the time,” Mr. Klieve said. “It comes from the front end! In the cow, it comes from the front end. But if you’re a hindgut fermenter, it goes the other way.”
. . .
Like cattle, kangaroos are also foregut fermenters. But instead of relying on methanogens to get rid of the unwanted hydrogen, kangaroos use different microbes that reduce hydrogen by producing not methane, but harmless acetic acids, the basis of vinegar.
. . .
“It’s going to be very difficult to meet the current production needs, particularly for the current global population, with kangaroo,” Ms. Henry said. “You need something like 10 kangaroos to produce the same amount of meat as one steer. You can’t herd them or fence them in.”
Undaunted, a few kangaroo meat entrepreneurs are pressing ahead, seeing methane emissions as a business opportunity.

More on How Federal Regulations Delay Oil Cleanup

(p. A15) First, the Environmental Protection Agency can relax restrictions on the amount of oil in discharged water, currently limited to 15 parts per million. In normal times, this rule sensibly controls the amount of pollution that can be added to relatively clean ocean water. But this is not a normal time.

Various skimmers and tankers (some of them very large) are available that could eliminate most of the oil from seawater, discharging the mostly clean water while storing the oil onboard. While this would clean vast amounts of water efficiently, the EPA is unwilling to grant a temporary waiver of its regulations.
Next, the Obama administration can waive the Jones Act, which restricts foreign ships from operating in U.S. coastal waters. Many foreign countries (such as the Netherlands and Belgium) have ships and technologies that would greatly advance the cleanup. So far, the U.S. has refused to waive the restrictions of this law and allow these ships to participate in the effort.
The combination of these two regulations is delaying and may even prevent the world’s largest skimmer, the Taiwanese owned “A Whale,” from deploying. This 10-story high ship can remove almost as much oil in a day as has been removed in total–roughly 500,000 barrels of oily water per day. The tanker is steaming towards the Gulf, hoping it will receive Coast Guard and EPA approval before it arrives.

Defenders of Climategate Benefit from Global Warming Fears

(p. A15) Last November there was a world-wide outcry when a trove of emails were released suggesting some of the world’s leading climate scientists engaged in professional misconduct, data manipulation and jiggering of both the scientific literature and climatic data to paint what scientist Keith Briffa called “a nice, tidy story” of climate history. The scandal became known as Climategate.

Now a supposedly independent review of the evidence says, in effect, “nothing to see here.”
. . .
One of the panel’s four members, Prof. Geoffrey Boulton, was on the faculty of East Anglia’s School of Environmental Sciences for 18 years. At the beginning of his tenure, the Climatic Research Unit (CRU)–the source of the Climategate emails–was established in Mr. Boulton’s school at East Anglia. Last December, Mr. Boulton signed a petition declaring that the scientists who established the global climate records at East Anglia “adhere to the highest levels of professional integrity.”
This purportedly independent review comes on the heels of two others–one by the University of East Anglia itself and the other by Penn State University, both completed in the spring, concerning its own employee, Prof. Michael Mann. Mr. Mann was one of the Climategate principals who proposed a plan, which was clearly laid out in emails whose veracity Mr. Mann has not challenged, to destroy a scientific journal that dared to publish three papers with which he and his East Anglia friends disagreed. These two reviews also saw no evil. For example, Penn State “determined that Dr. Michael E. Mann did not engage in, nor did he participate in, directly or indirectly, any actions that seriously deviated from accepted practices within the academic community.”
Readers of both earlier reports need to know that both institutions receive tens of millions in federal global warming research funding (which can be confirmed by perusing the grant histories of Messrs. Jones or Mann, compiled from public sources, that are available online at freerepublic.com). Any admission of substantial scientific misbehavior would likely result in a significant loss of funding.
It’s impossible to find anything wrong if you really aren’t looking.

Why We Should Drill in Our Backyards

(p. A15) As oil continues to gush from BP’s Macondo well and politicians posture, it is time for us to ask why we are drilling in such risky places when there is oil available elsewhere. The answer lies in the mantra NIMBY–“not in my back yard.”
. . .
In early June there was a blowout in western Pennsylvania. Did you see it on the nightly news? No, because it was capped in 16 hours.
. . .
Drilling can be done with greater environmental sensitivity onshore. For many years the Audubon Society actually allowed oil companies to pump oil for its privately owned sanctuaries in Louisiana and Michigan, but did so with strict requirements on the oil companies so that they would not disturb the bird habitat.
. . .
When kids play baseball, there is a risk that windows will get broken. Playing on baseball fields rather than in sand lots, however, lowers the risk considerably. Putting so much onshore land off limits to oil and gas development is like closing baseball parks. More windows will be broken and more blowouts result where they are difficult to prevent and stop.

Federal Regulations Slow Oil Cleanup Innovation

CostnerKevinOilWaterSeparator2010-07-04.jpg“One promising device is an oil-water separator backed by the actor Kevin Costner, right.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) Two decades after the Exxon Valdez oil spill, cleanup technology has progressed so little that the biggest advancement in the Gulf of Mexico disaster — at least in the public’s mind — is an oil-water separator based on a 17-year-old patent and promoted by the movie star Kevin Costner.
. . .
(p. A20) Ms. Kinner [co-director of the Coastal Response Research Center at the University of New Hampshire] and others cite many . . . reasons why cleanup technologies lag.
In testimony this month before Congress, Mr. Costner told of years of woe trying to market his separator, a centrifuge originally developed and patented in 1993 by the Idaho National Laboratory, for use in oil spills. One obstacle, he said, was that although his machines are effective, the water they discharge is still more contaminated than environmental regulations allow. He could not get spill-response companies interested in his machines, he said, without a federal stamp of approval.

India Government Spends Billions to Subsidize Fuel Use

IndiaGasDrumOnBike2010-06-29.jpg“An employee filled an oil drum in New Delhi on Friday. India’s government has decided to reduce popular fuel subsidies.” Source of caption and photo: online version of the NYT article quoted and cited below.

I smiled when I saw the ironic photo that appears above. It seems to imply that with government subsidies, even bicycle riders will buy motor fuel.

(p. B3) MUMBAI, India — The Indian government on Friday reduced popular fuel subsidies, a long-delayed change that will help policy makers reduce a big budget deficit but one that will also worsen already high inflation.

Policy makers said the government would stop subsidizing gasoline. Diesel, kerosene and natural gas would continue to receive support at a slightly lower level. India spent about $5.6 billion to subsidize fuel in the last fiscal year, which ended in March. State-owned energy companies added the equivalent of an additional $4.4 billion by selling fuel below its cost.
India and other big countries committed to eliminating energy subsidies at a Group of 20 meeting last year, but policy makers here had repeatedly put off the politically difficult change.

Fed Scientist Says Oil Spill Did Not Kill Most of Dead Turtles

(p. A9) A National Oceanic and Atmospheric Administration scientist says he believes most of the dead turtles that have been examined since the Gulf of Mexico oil spill died not from the oil or the chemical dispersants put into the water after the disaster, but from being caught in shrimping nets, though further testing may show otherwise.

Dr. Brian Stacy, a veterinary pathologist who specializes in reptiles, said that more than half the turtles dissected so far, most of which were found shortly after the spill, had sediment in their lungs or airways, which indicated they might have been caught in nets and drowned.
“The only plausible scenario where you would have high numbers of animals forcibly submerged would be fishery interaction,” he said. “That is the primary consideration for this event.”
Many times the usual number of turtles have been found stranded this year, but NOAA has cautioned from the beginning that the oil spill is not necessarily to blame.

Exposing the Hot Air of Wind Power

PowerHungryBKwsj.jpg

Source of book image: online version of the WSJ review quoted and cited below.

(p. A15) So you want to build a wind farm? OK, Mr. Bryce says, to start you’ll need 45 times the land mass of a nuclear power station to produce a comparable amount of power; and because you are in the middle of nowhere you’ll also need hundreds of miles of high-voltage lines to get the energy to your customers. This “energy sprawl” of giant turbines and pylons will require far greater amounts of concrete and steel than conventional power plants–figure on anywhere from 870 to 956 cubic feet of concrete per megawatt of electricity and 460 tons of steel (32 times more concrete and 139 times as much steel as a gas-fired plant).

Once you’ve carpeted your tract of wilderness with turbines and gotten over any guilt you might feel about the thousands of birds you’re about to kill, prepare to be underwhelmed and underpowered. Look at Texas, Mr. Bryce says: It ranks sixth in the world in total wind-power production capacity, and it has been hailed as a model for renewable energy and green jobs by Republicans and Democrats alike. And yet, according to the Electric Reliability Council of Texas, which runs the state’s electricity grid, just “8.7 percent of the installed wind capability can be counted on as dependable capacity during the peak demand period.” The wind may blow in Texas, but, sadly, it doesn’t blow much when it is most needed–in summer. The net result is that just 1% of the state’s reliable energy needs comes from wind.

MidAmerican Energy Gives Ben Nelson a $1.1 Million Ride from Georgia to Omaha

(p. 3B) LINCOLN — MidAmerican Energy is suing the state after state officials grounded a $1.1 million sales tax refund the company expected on the purchase of a corporate jet.

Under Nebraska’s 1987 economic development act, LB 775, companies can get sales tax refunds for such aircraft.
But the Nebraska Department of Revenue rejected the refund because MidAmerican’s multimillion-dollar Falcon 50EX jet, purchased in 2004, was used to transport U.S. Sen. Ben Nelson, D-Neb., on a trip between Albany, Ga., and Omaha on Nov. 28, 2006.
Using such planes for fundraising or transporting an elected official disqualifies a company from getting the sales tax benefit, State Tax Commissioner Doug Ewald ruled, citing prohibitions in LB 775.
MidAmerican, an Iowa-based energy firm headed by Omaha businessman David Sokol, is appealing.
The company is asking the Lancaster County District Court to overturn the department’s March ruling.
MidAmerican argued that a single trip taken by Nelson should not be enough to deny the refund. It also maintained that the state, under LB 775, should have based its ruling on the intended purpose of the airplane and can test that use only when the plane is purchased.
