Global Warming Might Help Mangrove Forests Thrive in Florida

(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.”

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.

“Engrossing, Brain-Tickling” Refutation of Al Gore’s Global Warming Assertions

“The Danish economist Bjorn Lomborg in “Cool It,” a documentary based on his book.” Source of caption and photo: online version of the NYT review quoted and cited below.

(p. C8) Debunking claims made by “An Inconvenient Truth” and presenting alternative strategies, “Cool It” finally blossoms into an engrossing, brain-tickling picture as many of Al Gore’s meticulously graphed assertions are systematically — and persuasively — refuted. (I was intrigued to hear Mr. Lomborg say, for instance, that the polar-bear population is more endangered by hunters than melting ice.)
. . .
. . . “Cool It” is all about the pep: playing down the talking heads and playing up the “git ‘er done.” If algae can suck up carbon dioxide and spit out oil, what on earth are we worrying about?

Prius Drivers Endanger Pedestrians and Cut in Front of Other Drivers

(p. B2) Jokes about BMW drivers being, on average, somewhat less than courteous are fairly common. They often run along the lines of, “Despite its good brakes, a BMW will usually stop with a jerk.” Sometimes the language is more colorful.
. . .
Paul K. Piff, a researcher at the Institute of Personality and Social Research at the University of California, Berkeley, has conducted a study linking bad driving habits with wealth.
. . .
In California, where the study was conducted, state law requires motorists to stop at crosswalks when pedestrians are present, allowing them to cross the road. Mr. Piff said his team selected a specific crosswalk to observe, then had a pedestrian appear on the edge of the curb as a car approached. As the pedestrian stepped into the road, a researcher marked down the driver’s reaction to the pedestrian. This was done with 152 drivers.
The team also watched a four-way-stop intersection over a week, noting how likely drivers were to cut in front of others when it was not their turn to go. In their observation of 274 cars, the researchers found that the more expensive ones were more likely to jump their turns in the four-way rotation, Mr. Piff said.
. . .
In the San Francisco Bay Area, where the hybrid gas-and-electric-powered Toyota Prius is considered a status symbol among the environmentally conscious, the researchers classified it as a premium model.
“In our higher-status vehicle category, Prius drivers had a higher tendency to commit infractions than most,” Mr. Piff said.

2013 Has “Largest One-Year Increase in Arctic Ice” Ever Recorded

(p. A8) Sea ice in the Arctic Ocean underwent a sharp recovery this year from the record-low levels of 2012, with 50 percent more ice surviving the summer melt season, scientists said Friday. It is the largest one-year increase in Arctic ice since satellite tracking began in 1978.

Climate Scientists Are Puzzled by “Lull” in Global Warming, Even with “Record Pace” of Greenhouse Gases

(p. D3) As unlikely as this may sound, we have lucked out in recent years when it comes to global warming.
The rise in the surface temperature of earth has been markedly slower over the last 15 years than in the 20 years before that. And that lull in warming has occurred even as greenhouse gases have accumulated in the atmosphere at a record pace.
The slowdown is a bit of a mystery to climate scientists.

Global Warming Allows Russians to Build Liquefied Natural Gas Plant in Arctic

“A rendering of Novatek’s proposed $20 billion liquefied natural gas plant on Russia’s Arctic coast, scheduled to be done by 2016.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. B1) YURKHAROVSKOYE GAS FIELD, Russia — The polar ice cap is melting, and if executives at the Russian energy company Novatek feel guilty about profiting from that, they do not let it be known in public.

From this windswept shore on the Arctic Ocean, where Novatek owns enormous natural gas deposits, a stretch of thousands of miles of ice-free water leads to China. The company intends to ship the gas directly there.
. . .
Novatek, in partnership with the French energy company Total and the China National Petroleum Corporation, is building a $20 billion liquefied natural gas plant on the central Arctic coast of Russia. It is one of the first major energy projects to take advantage of the summer thawing of the Arctic caused by global warming.
The plant, called Yamal LNG, would send gas to Asia along the sea lanes known as the Northeast Passage, which opened for regular international shipping only four years ago.
