Global Warming Might Help Mangrove Forests Thrive in Florida

“Mangrove forests, like in the Everglades, serve as spawning grounds and nurseries for fish and as habitat for a wide array of organisms. But salt marshes are also ecologically valuable.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A14) Much of the Florida shoreline was once too cold for the tropical trees called mangroves, but the plants are now spreading northward at a rapid clip, scientists reported Monday [December 30, 2013]. That finding is the latest indication that global warming, though still in its early stages, is already leading to ecological changes so large they can be seen from space.
. . .
The mangrove forests that fringe shorelines in the tropics are among the earth’s environmental treasures, serving as spawning grounds and nurseries for fish and as habitat for a wide array of organisms. Yet in many places, mangroves are critically endangered by shoreline development and other human activities.
So a climatic change that allows mangroves to thrive in new areas might well be seen as a happy development.
. . .
For years, scientists working in Florida had been noticing that mangroves seemed to be creeping northward along the coast. The new study is the first to offer a precise quantification of the change, using imagery from a satellite called Landsat, and to link it to shifts in the climate.
Patrick Gillespie, a spokesman for Florida’s Department of Environmental Protection, offered no specific comment on the new paper. By email, he said the agency had indeed “seen an increase in mangrove habitats to the north and inward along the Atlantic coast. It’s difficult to determine whether this is good or bad for the ecosystem because it’s happened over a relatively short period (p. A16) of time and may be a result of many factors.”

Organic and Kosher Chicken Have as Much Antibiotic-Resistant Bacteria as Regular Chicken

(p. D3) . . . after a trip to Israel for his sister’s bat mitzvah, Jack Millman came back to New York wondering whether the higher costs of kosher foods were justified.
“Most consumers perceive of kosher foods as being healthier or cleaner or somehow more valuable than conventional foods, and I was interested in whether they were in fact getting what they were paying for,” said Mr. Millman, 18 and a senior at the Horace Mann School in New York City.
That question started him on a yearlong research project to compare the prevalence of antibiotic-resistant E. coli bacteria on four types of chickens: those raised conventionally; organically; without antibiotics, and those slaughtered under kosher rules. “Every other week for 10 weeks, I would go and spend the entire Saturday buying chicken,” he said. “We had it specifically mapped out, and we would buy it and put it on ice in industrial-strength coolers given to us by the lab, and ship it out.”
All told, Mr. Millman and his mother, Ann Marks, gathered 213 samples of chicken drumsticks from supermarkets, butcher shops and specialty stores in the New York area.
Now they and several scientists have published a study based on the project in the journal F1000 Research. The results were surprising.
Kosher chicken samples that tested positive for antibiotic-resistant E. coli had nearly twice as much of the bacteria as the samples from conventionally raised birds did. And even the samples from organically raised chickens and those raised without antibiotics did not significantly differ from the conventional ones.

AquaBounty Has Waited More than 17 Years for FDA Approval

“The Enviropig Scientists at the University of Guelph, in Canada, developed these pigs to produce more environmentally friendly waste than conventional pigs. But the pigs were killed because the scientists could not get approval to sell them as food.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. 4) If patience is a virtue, then AquaBounty, a Massachusetts biotech company, might be the most virtuous entity on the planet.

In 1993, the company approached the Food and Drug Administration about selling a genetically modified salmon that grew faster than normal fish. In 1995, AquaBounty formally applied for approval. Last month, more than 17 years later, the public comment period, one of the last steps in the approval process, was finally supposed to conclude. But the F.D.A. has extended the deadline — members of the public now have until late April to submit their thoughts on the AquAdvantage salmon. It’s just one more delay in a process that’s dragged on far too long.
The AquAdvantage fish is an Atlantic salmon that carries two foreign bits of DNA: a growth hormone gene from the Chinook salmon that is under the control of a genetic “switch” from the ocean pout, an eel-like fish that lives in the chilly deep. Normally, Atlantic salmon produce growth hormone only in the warm summer months, but these genetic adjustments let the fish churn it out year round. As a result, the AquAdvantage salmon typically reach their adult size in a year and a half, rather than three years.
. . .
We should all be rooting for the agency to do the right thing and approve the AquAdvantage salmon. It’s a healthy and relatively cheap food source that, as global demand for fish increases, can take some pressure off our wild fish stocks. But most important, a rejection will have a chilling effect on biotechnological innovation in this country.
. . .
Then there’s the Enviropig, a swine that has been genetically modified to excrete less phosphorus. Phosphorus in animal waste is a major cause of water pollution, and as the world’s appetite for meat increases, it’s becoming a more urgent problem. The first Enviropig, created by scientists at the University of Guelph, in Canada, was born in 1999, and researchers applied to both the F.D.A. and Health Canada for permission to sell the pigs as food.
But last spring, while the applications were still pending, the scientists lost their funding from Ontario Pork, an association of Canadian hog farmers, and couldn’t find another industry partner. (It’s hard to blame investors for their reluctance, given the public sentiment in Canada and the United States, as well as the uncertain regulatory landscape.) The pigs were euthanized in May.
The F.D.A. must make sure that other promising genetically modified animals don’t come to the same end. Of course every application needs to be painstakingly evaluated, and not every modified animal should be approved. But in cases like AquaBounty’s, where all the available evidence indicates that the animals are safe, we shouldn’t let political calculations or unfounded fears keep these products off the market. If we do that, we’ll be closing the door on innovations that could help us face the public health and environmental threats of the future, saving countless animals — and perhaps ourselves.

Ignorance of Economics Makes U.S. Agency Complicit in Elephant Deaths

“Crushed ivory falls out of the crusher as the U.S. crushed its six-ton stock of confiscated ivory at the Rocky Mountain Arsenal National Wildlife Refuge . . . .” Source of caption and photo: online version of the WSJ article quoted and cited below.

The higher the price of ivory, the greater the incentive for ivory poachers to kill elephants. The U.S. Fish and Wildlife Service could have put their cache of ivory on the market, thereby increasing the supply, and reducing the price. If they had done so, they would have reduced the incentive of the poachers to poach. (This is basic price theory that I teach in each of my micro-economic principles classes.) Instead they crushed the ivory and thereby doomed some elephants to death, who otherwise could have been saved.

(p. A3) COMMERCE CITY, Colo.–The U.S. government spent the past 25 years amassing contraband ivory in a warehouse here, with pieces ranging from tiny statuettes to full elephant tusks tattooed by intricate carvings. Ultimately, the pile grew to six tons–equivalent to ivory from at least 2,000 elephants.

On Thursday, the stash collected by the U.S. Fish and Wildlife Service was pulverized by an industrial rock crusher as government officials, conservationists from around the world and celebrities gathered to watch the destruction.
The move, which follows similar events in the Philippines and Gabon in recent years, is part of a global effort to combat elephant poaching, on the rise because of growing demand for ivory trinkets in Asia. Proponents argue that crushing the ivory conveys to illegal traffickers and collectors that it has no value unless it is attached to an elephant.
. . .
But critics of the practice said they worry that destroying the coveted commodity, sometimes referred to as “white gold,” could instead create the perception that the world’s remaining ivory is more valuable–and drive poachers to kill more elephants for their tusks. “This could be self-defeating,” said Michael ‘t Sas-Rolfes, an independent conservation economist.
. . .
While praising efforts to preserve elephants, some in conservation circles consider crushing contraband ivory to be an ineffective strategy.
Kirsten Conrad, a wildlife conservation consultant who has studied the Chinese ivory market, said elephants could be better served if sustainably harvested ivory–from elephants that died from natural causes, for example–were regularly offered for sale.
The proceeds would give communities in Africa an incentive to better protect wildlife, and the steady supply would dissuade speculators in China from stockpiling, as she says they are doing now. A kilo of raw ivory can sell for up to $3,000. “We’re losing an elephant every 16 minutes,” she said. “We should look really hard at legal trade.”

The Market Incentive to Conserve

(p. 78) Carnegie, having satisfied himself that there was oil in the ground and a way to ship it to Pittsburgh, agreed to invest in Coleman’s oil company. While other prospectors fantasized only about the liquid gold that lay deep in the ground, Coleman and Carnegie believed that in the not too distant future the wells would run dry. To prepare for that day and turn it to their advantage, Coleman proposed–and Carnegie agreed–to construct a man-made lake, pump the oil from their wells into it, and leave it there until the supply dwindled and prices rose. Coleman and Carnegie waited for the region to run out of oil while their lake leaked thousands of barrels daily. Unable to find any efficient way to store the oil, they had to sell it on the open market.

Global Warming Has Little Correlation with Levels of Carbon Dioxide

The authors of the commentary quoted below are Harrison H. Schmitt and William Happer. Schmitt has at various times been a U.S. Senator, an Apollo 17 astronaut, and an adjunct professor of engineering at the University of Wisconsin–Madison. Happer is a professor of physics at Princeton University, and previously served as the Director at the Department of Energy’s Office of Energy Research.

(p. A19) Of all of the world’s chemical compounds, none has a worse reputation than carbon dioxide. Thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control of energy production, the conventional wisdom about carbon dioxide is that it is a dangerous pollutant. That’s simply not the case. Contrary to what some would have us believe, increased carbon dioxide in the atmosphere will benefit the increasing population on the planet by increasing agricultural productivity.

The cessation of observed global warming for the past decade or so has shown how exaggerated NASA’s and most other computer predictions of human-caused warming have been–and how little correlation warming has with concentrations of atmospheric carbon dioxide. As many scientists have pointed out, variations in global temperature correlate much better with solar activity and with complicated cycles of the oceans and atmosphere. There isn’t the slightest evidence that more carbon dioxide has caused more extreme weather.
. . .
We know that carbon dioxide has been a much larger fraction of the earth’s atmosphere than it is today, and the geological record shows that life flourished on land and in the oceans during those times. The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science.

Wind Power Fined $1 Million for Killing Birds

“A golden eagle flies over a wind turbine on Duke Energy’s wind farm in Converse County, Wyo.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. A17) The Justice Department announced late . . . [in the week of Nov. 17-23] that a subsidiary of Duke Energy has agreed to pay $1 million for killing golden eagles and other federally protected birds at two of the company’s wind projects in Wyoming. The guilty plea was a long-overdue victory for the rule of law and a sign that green energy might be going out of vogue.

As Justice noted in its news release, this is the first time a case has been brought against a wind company for violating the Migratory Bird Treaty Act. The 1918 law makes it a federal crime to kill any bird of more than 1,000 different species. Over the past few decades, federal authorities have brought hundreds of cases against oil and gas companies for killing birds, while the wind industry has enjoyed a de facto exemption. By bringing criminal charges against Duke for killing 14 golden eagles and 149 other protected birds, Justice has ended the legal double standard on enforcement.

Spain’s $11 Billion Per Year Slows Global Warming by 61 Hours

(p. A17) Today Spain spends about 1% of GDP throwing money at green energy such as solar and wind power. The $11 billion a year is more than Spain spends on higher education.
At the end of the century, with current commitments, these Spanish efforts will have delayed the impact of global warming by roughly 61 hours, according to the estimates of Yale University’s well-regarded Dynamic Integrated Climate-Economy model. Hundreds of billions of dollars for 61 additional hours? That’s a bad deal.

Farm Land Reverts to Forest as Farmers Move to Cities

“NEW GROWTH; Marta Ortega de Wing once raised pigs in Chilibre, Panama, on land now reverting to nature, a trend dimming the view of primeval forests as sacred.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) CHILIBRE, Panama — The land where Marta Ortega de Wing raised hundreds of pigs until 10 years ago is being overtaken by galloping jungle — palms, lizards and ants.

Instead of farming, she now shops at the supermarket and her grown children and grandchildren live in places like Panama City and New York.
Here, and in other tropical countries around the world, small holdings like Ms. Ortega de Wing’s — and much larger swaths of farmland — are reverting to nature, as people abandon their land and move to the cities in search of better livings.
These new “secondary” forests are emerging in Latin America, Asia and other tropical regions at such a fast pace that the trend has set off a serious debate about whether saving primeval rain forest — an iconic environmental cause — may be less urgent than once thought. By one estimate, for every acre of rain forest cut down each year, more than 50 acres of new forest are growing in the tropics on land that was once farmed, logged or ravaged by natural disaster.
“There is far more forest here than there was 30 years ago,” said Ms. Ortega de Wing, 64, who remembers fields of mango trees and banana plants.
The new forests, the scientists argue, could blunt the effects of rain forest destruction by absorbing carbon dioxide, the leading heat-trapping gas linked to global warming, one crucial role that rain forests play. They could also, to a lesser extent, provide habitat for endangered species.

Innovative Fracking Entrepreneurs Again Show that Energy Is Only Limited by Ingenuity

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

(p. 7) In “The Frackers,” Gregory Zuckerman sets out a 25-year narrative that focuses on the half-dozen or so Texas and Oklahoma energy companies behind the fracking boom, especially Chesapeake Energy, the Oklahoma City giant that is the Exxon Mobil of fracking. Technologies are born. Gushers gush. And fortunes are made and lost.

In the process, Mr. Zuckerman assembles a chorus of little-heard American voices, from George Mitchell, the Greek goatherd’s son whose company first perfected fracking, to Chesapeake’s two founders, Aubrey K. McClendon and Tom L. Ward.
. . .
Geologists knew that layers of shale spread across North America contained commercial amounts of oil and gas, but not until a young geologist at Mr. Mitchell’s company, Mitchell Energy, perfected a new “secret sauce” of water-based fracturing liquids in the early 1990s did layers of shale — in Mitchell’s case, the Barnett Shale of North Texas — melt away and begin to yield jaw-dropping gushers.
Oryx Energy, a company that was based in Dallas, was among the first to pair fracking with horizontal drilling, producing even more startling results. Still, it took years, Mr. Zuckerman writes, before larger businesses, especially the skeptical major oil companies, fathomed what their smaller rivals had achieved. This allowed what were flyspeck outfits like Chesapeake to lease vast acreage in shale-rich areas, from Montana to eastern Pennsylvania.
