Large Indian Tribes Hurt by Obama Regulations on Coal

(p. 1) . . . some of the largest tribes in the United States derive their budgets from the very fossil fuels that Mr. Trump has pledged to promote, including the Navajo in the Southwest and the Osage in Oklahoma, as well as smaller tribes like the Southern Ute in Colorado. And the Crow are among several Indian nations looking to the president’s promises to nix Obama-era coal rules, pull back on regulations, or approve new oil and gas wells to help them lift their economies and wrest control (p. 14) from a federal bureaucracy they have often seen as burdensome.
The president’s executive order on Tuesday [March 28, 2017], which called for a rollback of President Barack Obama’s climate change rules, is a step toward some of these goals.
At the tribes’ side is Ryan Zinke, who as the new interior secretary is charged with protecting and managing Indian lands, which hold an estimated 30 percent of the nation’s coal reserves west of the Mississippi and 20 percent of known oil and gas reserves in the United States.
In a recent interview, Mr. Zinke noted that he was once adopted into the Assiniboine and Sioux tribes and said he would help native nations get fossil fuels to market.
“We have not been a good partner in this,” he said. “The amount of bureaucracy and paperwork and stalling in many ways has created great hardship on some of the poorest tribes.
“A war on coal is a war on the Crow people,” he continued. “President Trump has promised to end the war.”

Rain and Snow End California Drought

(p. A18) After six years of a prolonged drought in California, it is all but over. On Friday [April 7, 2017], Gov. Jerry Brown ended the drought emergency for the vast majority of the state. The drought had reduced Folsom Lake, a major reservoir in Northern California, to less than a third of its capacity in 2015, and all but wiped out the Sierra Nevada snowpack.
. . .
But the state’s hydrologic picture brightened significantly beginning in October 2016, when a series of massive storms drenched Northern California. The rain and snow continued through the winter, swelling major reservoirs to the point that officials were forced to make releases.
Meanwhile, the state’s snowpack made an impressive recovery. As of Friday, the water content in the state’s snowpack was about 160 percent of what is considered normal for this time of year. By comparison, the snowpack was reported as about 5 percent of average the day Mr. Brown stood on the barren field and ordered mandatory water conservation.

Geoengineering Could Cheaply and Quickly Counter Global Warming

(p. B1) Last month, scholars from the physical and social sciences who are interested in climate change gathered in Washington to discuss approaches like cooling the planet by shooting aerosols into the stratosphere or whitening clouds to reflect sunlight back into space, which may prove indispensable to prevent the disastrous consequences of warming.
Aerosols could be loaded into military jets, to be sprayed into the atmosphere at (p. B4) high altitude. Clouds at sea could be made more reflective by spraying them with a fine saline mist, drawn from the ocean.
. . .
. . . , geoengineering needs to be addressed not as science fiction, but as a potential part of the future just a few decades down the road.
“Today it is still a taboo, but it is a taboo that is crumbling,” said David Keith, a noted Harvard physicist who was an organizer of the conclave.
. . .
Geoengineering would be cheap enough that even a middle-income country could deploy it unilaterally. Some scientists have estimated that solar radiation management could cool the earth quickly for as little as $5 billion per year or so.

Since 1880 North America Is Warmer by One and a Half Degrees Fahrenheit

(p. A23) Anyone who has read the 2014 report of the Intergovernmental Panel on Climate Change knows that, while the modest (0.85 degrees Celsius, or about 1.5 degrees Fahrenheit) warming of the earth since 1880 is indisputable, as is the human influence on that warming, much else that passes as accepted fact is really a matter of probabilities. That’s especially true of the sophisticated but fallible models and simulations by which scientists attempt to peer into the climate future. To say this isn’t to deny science. It’s to acknowledge it honestly.

U.S. Science Agencies Omit Margin of Error in Warming Stats

(p. A13) The year 2016 was the warmest ever recorded–so claimed two U.S. agencies, NASA’s Goddard Institute for Space Studies and the Commerce Department’s National Oceanic and Atmospheric Administration. Except it wasn’t, according to the agencies’ own measures of statistical uncertainty.
Such fudge is of fairly recent vintage. Leaving any discussion of the uncertainty interval out of press releases only became the norm in the second year of the Obama administration. Back when he was presenting the 2008 numbers, NASA’s James Hansen, no slouch in raising climate alarms, nevertheless made a point of being quoted saying such annual rankings can be “misleading because the difference in temperature between one year and another is often less than the uncertainty in the global average.”
Statisticians wouldn’t go through the trouble of assigning an uncertainty value unless it meant something. Two measurements separated by less than the margin of error are the same. And yet NASA’s Goddard Institute, now under Mr. Hansen’s successor Gavin Schmidt, put out a release declaring 2014 the “warmest year in the modern record” when it was statistically indistinguishable from 2005 and 2010.
. . .
. . . other countries like the U.K. and Japan also do sophisticated monitoring and end up with findings roughly similar to the findings of U.S. agencies, yet they don’t feel the need to lie about it. For instance, the U.K. Met Office headlined its 2016 report “one of the warmest two years on record.” A reader only had to progress to the third paragraph to discover that the difference over 2015 was one-tenth the margin of error.

British Government Environmentalists Increase London Air Pollution

(p. A4) London is choking from record levels of pollution, much of it caused by diesel cars and trucks, as well as wood-burning fires in private homes, a growing trend.
. . .
London’s air pollution today is different from seven decades ago, and more insidious. No longer thick as “pea soup,” as it was traditionally described, the city’s air is now laced with nitrogen dioxide — a toxic gas mostly produced by vehicles with diesel engines.
. . .
The current problem is, in part, an unintended consequence of previous efforts to aid the environment.
The British government provided financial incentives to encourage a shift to diesel engines because laboratory tests suggested that would cut harmful emissions and combat climate change. Yet, it turned out that diesel cars emit on average five times as much emissions in real-world driving conditions as in the tests, according to a British Department for Transport study.
“No one at the time thought of the consequences of increased nitrogen dioxide emissions from diesel, and the policy of incentivizing diesel was so successful that an awful lot of people bought diesel cars,” said Anna Heslop, a lawyer at ClientEarth, an environmental law firm that last year forced the British government to produce a better plan to improve air quality.
. . .
Bob Miller, 69, a cabdriver who has crisscrossed London for 30 years, wasn’t convinced. He has lost faith in recommendations by policy makers and experts, he said.
“We were told how wonderful diesel is, how they were supposed to be cleaner than petrol,” Mr. Miller said, idling his cab in heavy traffic with the window open.
“The experts make the rules, then they’re wrong,” he said, shaking his head. “I give up.”

Coastal Damage Caused by Storm Surges at High Tide, Not by Tiny Rise in Sea Levels

(p. A11) When Teddy Roosevelt built his Sagamore Hill on Long Island, he did so a quarter mile from shore at an elevation of 115 feet not because he disdained proximity to the beach or was precociously worried about climate change. The federal government did not stand ready with taxpayer money to defray his risk.
Estimates vary, but sea levels may have risen two millimeters a year over the past century. Meanwhile, tidal cycles along the U.S. east coast range from 11 feet every day (in Boston) to two feet (parts of Florida).
On top of this, a “notable surge event” can produce a storm surge of seven to 23 feet, according to a federal list of 10 hurricanes over the past 70 years.
We should not exaggerate the degree to which homeowners are being asked to shoulder their own risks. Washington is doling out five-figure checks to Jersey homeowners to raise houses on pilings to reduce the federal government’s future rebuilding costs. But, to state the obvious, normal tidal variation plus storm surge is the danger to coastal property. Background sea-level rise is a non-factor. A FEMA study from several years ago found that fully a quarter of coastal dwellings are liable to be destroyed over a 50-year period.
Though it pleased New York Gov. Andrew Cuomo to pretend Superstorm Sandy in 2012 was caused by global warming, the storm wasn’t even a hurricane by the time it hit shore–it just happened to hit at peak tide. Sure, certain people in Florida and elsewhere like to conflate the two. It’s in their interests to do so.

Northwest Passage Cruise Ship Sells Out in Three Weeks

(p. B1) Norwegian explorer Roald Amundsen took three years in the early 1900s to complete the first successful navigation of the Northwest Passage, the ice-choked arctic sea route connecting the Pacific and Atlantic. Only in 1944, did a ship make it through in a single year.
This summer, the Crystal Serenity–a 820-foot-long, 13-deck cruise ship with a casino, a movie theater, six restaurants and a driving range–is planning to steam through in less than a month.
Operated by Los Angeles-based Crystal Cruises LLC, the trip sold out in three weeks, with some 1,000 would-be passengers paying about $22,000 each.
. . .
About 200 ships have traversed the 900-mile route since Amundsen’s voyage between 1903 and 1906. But most of those have gone through just in the last decade as ocean warming diminishes ice cover further, and for longer, during the summer months.

Glorious Colors of Fall Leaves Last Longer with Global Warming

(p. A20) IONA, Nova Scotia — A century ago, the flaming fall foliage in Nova Scotia would have long faded by early November. But today, some of the hills are still as nubbly with color as an aunt’s embroidered pillow.
Climate change is responsible, scientists say. As the seasonal change creeps later into the year, not only here but all across the northern United States and Canada, the glorious colors will last longer, they predict — a rare instance where global warming is giving us something to look forward to.
“If climate change makes eastern North America drier, then autumn colors will be spectacular, as they are on the Canadian Shield in dry summers, especially the red maples,” said Root Gorelick, a biology professor at Carleton University in Ottawa. The Canadian Shield is a broad ring of forests and ancient bedrock that extends hundreds of miles from the shores of Hudson Bay.
Over the very long term, the warming planet may have a negative effect on fall foliage, but even then any adverse impact is uncertain. It is not just an aesthetic question, but an economic one as well: The changing colors drive billions of dollars in “leaf peeping” tourism in Canada and the United States.
“From a peeper’s point of view, it’s good news,” said Marco Archetti, the lead author of a 2013 paper at Harvard on predicting climate change impacts on autumn colors in New England.
. . .
The Harvard study, which looked at the percentage and duration of autumn color in Harvard Forest in central Massachusetts from 1993 to 2010, predicted that with current climate change forecasts, the duration of the fall display would increase about one day for every 10 years. Look at it this way: Children born this year could have an extra week to enjoy the colors by the time they are 70.
The study further analyzed data for trees that turn red: red maple, sugar maple, black gum, white oak, red oak, black oak, black cherry and white ash. Only in white ash trees did the duration and full display of color decrease. In the others, the amount and duration of red leaves increased over the course of 18 years.
The Harvard study used data collected by John O’Keefe, the museum coordinator, now emeritus, at Harvard Forest, who made his observations by eye — estimating the percentage of colored leaves for each species and the duration from when 10 percent of a tree’s leaves turned color to when 90 percent had turned.
Those observations have been validated by Andrew Richardson, a professor of evolutionary biology at Harvard, who has since set up a network of 350 “phenocams,” cameras that quantify the duration and intensity of autumn colors in locations from Alaska to Hawaii, Arizona to Maine and up into Canada.
“John’s direct observations on the ground line up pretty well with the camera data,” Professor Richardson said.

Winemakers Adapt to Global Warming with Owls and Technology

(p. 7) As California heats up, winemakers are confronting new challenges large and small — some very small.
Mice, voles and gophers love vineyards. “We’re seeing more pest pressures due to warmer winters,” Ms. Jackson said, walking through rows of cabernet grapes. Another emerging issue: Grapes ripen earlier, and swallows and crows are eating fruit before the harvest. “It’s a big problem,” she said.
That explains the owls. Sixty-eight boxes are occupied by hungry barn owls; during the harvest, a falconer comes to some vineyards every day, launching a bird of prey to scare away other birds with a taste for grapes.
The Jacksons have also begun analyzing their crops with increasingly sensitive tools. Ms. Jackson recently installed devices that measure how much sap is in the vines. They transmit the data over cellular networks to headquarters, where software calculates how much water specific areas of vineyards do or don’t need. “Data-driven farming,” Ms. Jackson said.
The Jacksons are also monitoring their crops using drones equipped with sensors that detect moisture by evaluating the colors of vegetation. The wrong color can indicate nutritional deficiencies in the crops, or irrigation leaks.
“Previously, it would require an experienced winemaker to go and look at the grapes,” said Clint Fereday, the company’s director of aviation. “Now we can run a drone, tag an area of the vines with GPS, and go right to the spot that has a problem.”
The drones have other uses, too. An infrared camera can scan for people guarding illicit marijuana operations on nearby lands.
Not all the changes being made on the Jackson vineyards involve advanced technology. Some are simply ancient farming techniques that the drought has made increasingly relevant.
Field hands plant cover crops, like rye and barley, between every second row of vines, to help keep the soil healthy. The family is stepping up its composting program. Pressed grapes are composted, then placed beneath rows of vines, since the organic matter is better at retaining moisture than soil.
Ms. Jackson’s husband, Shaun Kajiwara, is a vineyard manager for the company, overseeing the grapes that go into many of the upscale labels.
. . .
Ultimately, Mr. Kajiwara believes that with the right mix of new rootstocks, cover crops and fortuitous rainfall, some of the Jackson vineyards might not need irrigation at all. “In a few years, I think we could be dry-farmed up here,” he said. “Our reservoir will just be insurance.”
It is a snapshot of the future for the Jackson family: a vineyard north of traditional wine country, where natural features might offset some of the deleterious effects wrought by climate change. And, in combination with the adaptations Ms. Jackson has put in place, it might just be enough to allow the company to keep making fine wines for many years to come.
