When Consumers Want More Trucks and SUVs, Feds Mandate More Hybrids and Electrics

(p. B1) DETROIT — While American consumers were taking advantage of low gas prices to buy trucks and sport utility vehicles in large numbers, some automakers delayed investing in slower-selling electrified vehicles.
But with increases in federal fuel-economy standards looming in 2017, car companies are hustling to bring out hybrid and electric models to help them meet the new rules — even though electrified vehicles make up only 2 percent of overall sales.
The federal government has mandated corporate average fuel economy of 54.5 miles per gallon by 2025. But companies need to meet an interim standard of about 37 m.p.g. by next year.
Now, despite declining gas prices, automakers are showing off a raft of electric and hybrid models this week at the annual North American International Auto Show in Detroit.

Colorful Coral Reef Is Thriving in Hot Water

(p. D1) In 2003, researchers declared Coral Castles dead.
On the floor of a remote island lagoon halfway between Hawaii and Fiji, the giant reef site had been devastated by unusually warm water. Its remains looked like a pile of drab dinner plates tossed into the sea. Research dives in 2009 and 2012 had shown little improvement in the coral colonies.
Then in 2015, a team of marine biologists was stunned and overjoyed to find Coral Castles, genus Acropora, once again teeming with life. But the rebound came with a big question: Could the enormous and presumably still fragile coral survive what would be the hottest year on record?
This month, the Massachusetts-based research team finished a new exploration of the reefs in the secluded Phoenix Islands, a tiny Pacific archipelago, and were thrilled by what they saw. When they splashed out of an inflatable dinghy to examine Coral Castles closely, they were greeted with a vista of bright greens and purples — unmistakable signs of life.
“Everything looked just magnificent,” said Jan Witting, the expedition’s chief scientist and a researcher at Sea Education Association, based in Woods Hole, Mass.
. . .
(p. D6) If Coral Castles can continue to revive after years of apparent lifelessness, even as water temperatures rise, there might be hope for other reefs with similar damage, said another team member, Randi Rotjan, a research scientist who led and tracked the Phoenix Islands expedition from her base at the New England Aquarium in Boston.
No one actually knows what drives reef resilience or even what a coral reef looks like as it is rebounding. In remote, hard-to-get-to places, our understanding of coral is roughly akin to a doctor’s knowing only what a patient looks like in perfect health and after death, Dr. Rotjan said.

Ministry of Justice Bus Unjustly Cuts Ahead of 99 Vehicles in Nigerian Gas Line

(p. A1) LAGOS, Nigeria — Young men became entangled in a swirl of flying fists. Gas station workers swatted away boys hoping to fill their plastic cans. A mother with a sleeping baby in her minivan was chased off, rightly accused of jumping the line. A driver eager to get ahead crashed into several cars, the sound of crunching metal barely registering amid the noise.
Nigerians were getting used to days like this.
But then came the ultimate insult to everyone waiting at the Oando mega gas station: A bus marked Ministry of Justice rolled up to a pump, leapfrogging no fewer than 99 vehicles. “Service With Integrity” was painted on its door. A gas station supervisor who calls herself Madame No Nonsense stepped aside to let it fuel up before anyone else. The crowd howled at the injustice.
Plummeting oil prices have set off an economic unraveling in Nigeria, one of the world’s top oil producers, and the collective anger of a fed-up nation was pouring out.
. . .
(p. A8) President Muhammadu Buhari is urging patience, noting that when he took office last year he inherited a corruption-plagued mess.
. . .
. . . the government says the supply is getting better. It has finally fired up Nigeria’s three rickety oil refineries, and the wait in Lagos improved drastically last week. Eventually, officials say, Nigeria will make all of its own gasoline.

Iowa State Students Go Bananas to Save (or Harm?) African Children

(p. A11) Student activists at Iowa State University are up in arms after researchers offered to pay them almost a thousand bucks to eat some genetically modified banana. The bananas, created by an Australian scientist, contain high levels of beta carotene, which converts to vitamin A when eaten.
. . .
“Those students are acting out of ignorance,” Jerome Kubiriba, the head of the National Banana Research Program in Uganda, tells me. “It’s one thing to read about malnutrition; it’s another to have a child who is constantly falling sick yet, due to limited resources, the child cannot get immediate and constant medical care. If they knew the truth about the need for vitamin A and other nutrients for children in Uganda and Africa, they’d get a change of heart.”

Scientists Reviving Extinct Tortoise Species

(p. D1) . . . the story of extinct Galápagos tortoises has taken a strange, (p. D5) and hopeful, twist.
More than a century ago, it turns out, sailors dumped saddlebacked tortoises they did not need into Banks Bay, near Wolf Volcano on Isabela Island. Luckily, tortoises can extend their necks above water and float on their backs. Many of them made it to shore, lumbered across the lava fields and interbred with Isabela’s native domed tortoises.
In 2008, scientists tagged and collected blood samples from more than 1,600 tortoises living on the flanks of the volcano. Back in the laboratory, there was a genetic eureka: Eighty-nine of the animals were part Floreana, whose full genetic profile DNA had been obtained from museum samples.
Some had genes indicating their parents were living purebred Floreana tortoises, hinting that the species may not be extinct after all.
Seventeen tortoises were shown to have high levels of Pinta DNA. Tortoises can live for more than 150 years, so some of them may well be George’s immediate next of kin.
Last month, scientists went back to find them. Their plan was to capture and separate tortoises with high levels of Pinta and Floreana DNA, and then breed animals that are genetically closest to the original species.
In just a few generations, it should be possible to obtain tortoises with 95 percent of their “lost” ancestral genes, the scientists said.

Iceland Project Turns 95% of Carbon Dioxide into Calcite Rock

(p. A6) For years, scientists and others concerned about climate change have been talking about the need for carbon capture and sequestration.
. . .
Among the concerns about sequestration is that carbon dioxide in gaseous or liquid form that is pumped underground might escape back to the atmosphere. So storage sites would have to be monitored, potentially for decades or centuries.
But scientists at Lamont-Doherty Earth Observatory at Columbia University and other institutions have come up with a different way to store CO2 that might eliminate that problem. Their approach involves dissolving the gas with water and pumping the resulting mixture — soda water, essentially — down into certain kinds of rocks, where the CO2 reacts with the rock to form a mineral called calcite. By turning the gas into stone, scientists can lock it away permanently.
One key to the approach is to find the right kind of rocks. Volcanic rocks called basalts are excellent for this process, because they are rich in calcium, magnesium and iron, which react with CO2.
Iceland is practically all basalt, so for several years the researchers and an Icelandic utility have been testing the technology on the island. The project, called CarbFix, uses carbon dioxide that bubbles up naturally with the hot magma that powers a geothermal electrical generating plant 15 miles east of the capital, Reykjavik.
. . .
Early signs were encouraging: . . .
. . .
The scientists found that about 95 percent of the carbon dioxide was converted into calcite. And even more important, they wrote, the conversion happened relatively quickly — in less than two years.
“It’s beyond all our expectations,” said Edda Aradottir, who manages the project for the utility, Reykjavik Energy.
. . .
. . . the researchers say that there is enough porous basaltic rock around, including in the ocean floors and along the margins of continents.

New Technology Reveals Huge Helium Supplies

(p. A8) Helium’s role in superconductivity and other applications has grown so much that there have been occasional shortages. The gas forms in nature through radioactive decay of uranium and thorium, but exceedingly slowly; in practical terms, all the helium we will ever have already exists. And because it does not react with anything and is light, it can easily escape to the atmosphere.
. . .
But now scientists have figured out a way to explore specifically for helium. Using their techniques, they say, they have found a significant reserve of the gas in Tanzania that could help ease concerns about supplies.
. . .
Working with scientists from the University of Oxford and a small Norwegian start-up company called Helium One, the researchers prospected in a part of Tanzania where studies from the 1960s suggested helium might be seeping from the ground. The area is within the East African Rift, a region where one of Earth’s tectonic plates is splitting. The rifting has created many volcanoes.
Dr. Gluyas said the gas discovered in Tanzania may be as much as 10 percent helium, a huge proportion compared with most other sources. The researchers say the reservoir might contain as much as 54 billion cubic feet of the gas, or more than twice the amount currently in the Federal Helium Reserve, near Amarillo, Tex., which supplies about 40 percent of the helium used in the United States and is being drawn down.
The next step would be for Helium One or one of the major helium suppliers around the world to exploit the find.

Ozone Hole Shrinking

(p. A4) Nearly three decades after the world banned chemicals that were destroying the atmosphere’s protective ozone layer, scientists said Thursday that there were signs the atmosphere was on the mend.
The researchers said they had found “fingerprints” indicating that the seasonal ozone hole over Antarctica, a cause of concern since it was discovered in 1984, was getting smaller.
. . .
“This is just the beginning of what is a long process,” said Susan Solomon, an atmospheric chemist at the Massachusetts Institute of Technology and lead author of the study, published in the journal Science.
. . .
Ozone depletion is a complex process that is affected by variables like temperature, wind and volcanic activity. So Dr. Solomon and the other researchers looked at data from satellites and balloon-borne instruments taken each September. That made it easier to separate the effects of the decline in chlorine atoms from the other factors. They also compared the data with the results of computer models.
The study found that the ozone hole had shrunk by about 1.5 million square miles, or about one-third the area of the United States, from 2000 to 2015.

Wild Turkeys, Reintroduced by Government, Now Threaten Government Mail Delivery

(p. A25) HILLSDALE, N.J. — In some neighborhoods of this placid New Jersey borough in Bergen County, they are seemingly everywhere — waddling by the dozen in the road, perched on car roofs, pecking at the tires of delivery trucks.
But wild turkeys, which were wiped out in the state by the mid-1800s, put on their most brazen display on Tuesday [Feb., 16, 2016], when a letter carrier felt trapped in his truck and telephoned his boss for help.
“Hey sarge,” the postmaster said in a 911 call to the Hillsdale Police Department. “You’re not going to believe this, but I got a carrier that’s being attacked by wild turkeys and won’t let him deliver the mail.”
The letter carrier, who was not identified, was inside his truck on Esplanade Drive, surrounded by four or five turkeys, when two officers arrived, according to Capt. Sean Smith of the Police Department. “The first officer attempted to blow the siren and that didn’t work,” he said on Thursday. “Then the other officer got out of his car and ran aggressively toward the turkeys and that did the trick.”
. . .
While New Jersey environmental officials say they are unaware of anyone’s being physically harmed by a turkey, the large birds are intimidating. The state’s Department of Environmental Protection, which reintroduced turkeys to the state in the 1970s, says that there are now about 25,000 statewide. “It’s a success story,” said Larry Hajna, a spokesman for the environmental agency.
. . .
. . . some local officials and residents say face-to-face turkey encounters are increasing and can be scary. The postmaster who placed the 911 call in Hillsdale told the police that the turkey situation was “crazy.” “I mean, they’re actually attacking, biting,” he said. “They chase the trucks — everything.” The police sergeant simply said, “Wow.”

President Kenyatta Burns Ivory, Raising Its Price, and Increasing the Incentive for Poachers to Kill Elephants

If President Kenyatta wants to save elephants, instead of burning ivory, he should sell it on the open market, moving the supply curve to the right, and lowering the price of ivory. A lower price of ivory would reduce the incentive for poachers to kill elephants.

(p. 10) NAIROBI, Kenya — What do you do when you have more than $100 million worth of ivory sitting around, just collecting dust?
You burn it, of course.
That is what Kenya did on Saturday, when President Uhuru Kenyatta lit a huge pyre of elephant tusks as a way to show the world that Kenya is serious about ending the illegal ivory trade, which is threatening to push wild elephants to extinction.
“No one, and I repeat, no one, has any business in trading in ivory, for this trade means death — the death of our elephants and the death of our natural heritage,” Mr. Kenyatta said.

Utilities Shifting Back to Fossil Fuels to Reduce Electricity Prices

(p. B1) KEADBY, England — A wind farm here, along the River Trent, cranks out enough clean electricity to power as many as 57,000 homes. Monitored remotely, the windmills, 34 turbines each about 400 feet high, require little attention or maintenance and are expected to produce electricity for decades to come.
“They’re very well behaved,” said Sam Cunningham, the wind farm’s manager, as she drove around the almost three-square-mile site.
The owner of the wind farm, the British electricity company SSE, has been betting big on turbines as well as other renewables for years, with multibillion-dollar investments that have made the utility the country’s leading provider of clean power. In theory, last year’s United Nations climate accord in Paris should have been a global validation of the company’s business strategy.
But instead of doubling down, the utility is rethinking its energy mix, reconsidering plans for large wind farms and even restarting a mothballed power plant that runs on fossil fuel.
The moves reflect the existential debate faced by many major power companies, as they grapple with real-world energy economics and shifts in government policy. The calculus for fossil fuels can be more favorable at a time when energy prices are low and countries like Britain are rethinking subsidies on renewables to keep electricity prices down.”
