Indonesia Bans the Burning
Of Peatland; Will Help Reduce CO2 Emissions
Indonesian President Joko Widodo announced a moratorium
earlier this week on the conversion of carbon-rich peatlands into agricultural land — a move that could prevent hundreds of millions of tons of CO2 from being emitted annually. In recent years, landowners and companies have been draining, drying, and often burning the country’s abundant peat-filled wetlands to make way for palm oil plantations and other farmland. Fires in 2015 caused more than a half-million people to be treated for respiratory problems and $16.1 billion in economic damage, according to the United Nations Environment Program
. Widodo’s moratorium protects peatlands of any depth and orders companies to restore any peatlands they have converted. "This regulation will be a major contribution to the Paris climate agreement and a relief to millions of Indonesians who suffer the effects of toxic haze from peat fires," said Nirarta Samadhi
, Indonesia country director for the World Resources Institute.

Google to Power Itself Using
100 Percent Renewable Energy in 2017
Google announced that it has purchased enough solar and wind capacity, 2.6 gigawatts, to run entirely on renewable energy
The company, whose data centers and offices consume as much electricity as the city of San Francisco, will get most of its wind
energy from the U.S. Midwest, the Netherlands, Norway, and Sweden, and its solar from contracts in North Carolina and Chile. Google bought its first wind power in 2010 and is now the world’s largest corporate buyer of renewable energy. “The science tells us that tackling climate change is an urgent global priority,” said Urs Hölzle, Google’s senior vice president of technical infrastructure. “We believe the private sector, in partnership with policy leaders, must take bold steps and that we can do so in a way that leads to growth and opportunity.”
Interview: Unusually Warm Arctic
May Have Impact on Global Weather
This year will almost certainly go down as the warmest on record in the Arctic, with autumn temperatures soaring 36 degrees F above historic norms.
Among the climate scientists attempting to make sense of the rapid changes sweeping the Arctic is Jennifer Francis of Rutgers University. Francis has propounded the widely discussed theory that swiftly rising temperatures in the Arctic, which are closely intertwined with the loss of sea ice, are changing the shape of the jet stream and altering the weather of the northern hemisphere. In an interview with Yale Environment 360
, Francis explains why large portions of the Arctic are experiencing temperatures more typical of New York City and warns that we ignore climate upheaval at the North Pole at our own peril. "The speed of the change is what is very disturbing to me," says Francis, "because it's such an indicator of what's happening to the planet as a whole."

To Fight Air Pollution, Four
Cities Announce Ban on Diesel Cars By 2025
Four of the world’s largest cities announced Friday that they will ban diesel cars by 2025
in an effort to cut air pollution.
Traffic and smog in the outskirts of Paris.
Leaders from Paris, Madrid, Athens, and Mexico City made the declaration at the C40 Mayors Summit, a biennial meeting of civic leaders concerned about climate change. Toxic air is responsible for an estimated 3 million premature deaths
each year, according to recent research by the World Health Organization. While diesel engines burn fuel more efficiently and therefore release less carbon dioxide, they do produce nitrogen dioxide and particulates that can inflame and damage people’s lungs. “Mayors have already stood up to say that climate change is one of the greatest challenges we face,” said Anne Hidalgo, the mayor of Paris. “Today, we also stand up to say we no longer tolerate air pollution and the health problems and deaths it causes.”

Soils Could Release 55 Trillion
Kilograms of Carbon By Mid-Century
The world’s soils act as critical storage for carbon, sequestering carbon from the atmosphere to fuel plant and microbial activity.
Permafrost in Greenland.
But scientists warned this week
that as soils warm in response to climate change, they could release 55 trillion kilograms of carbon by mid-century — roughly equivalent to the projected emissions of the United States, or 17 percent of all countries, during that same period. The largest losses will be from high-latitude ecosystems, the new study, led by scientists at the Yale School of Forestry & Environmental Studies and published in the journal Nature
, said. This includes Arctic and sub-Arctic permafrost, where colder temperatures and slow microbial activity have led to the buildup of massive carbon reserves over thousands of years. The scientists found that for every 1 degree Celsius of global warming, soils will release approximately 30 trillion kilograms of carbon into the atmosphere, or twice the annual emissions from human activities.

This Year’s Coral Die-Off on
Great Barrier Reef Was Worst Ever Recorded
The Great Barrier Reef in Australia experienced its worst recorded coral die off this year, with one region losing an average
Dead table corals on the Great Barrier Reef.
67 percent of its shallow-water coral, scientists confirmed this week
. The mass die-off event was caused by abnormally warm water temperatures in the Pacific Ocean, which can trigger corals to expel their algae and calcify and turn white, a process known as coral bleaching. Corals can recover from bleaching, but many never do. “Most of the losses in 2016 have occurred in the northern, most-pristine part of the Great Barrier Reef,” said Terry Hughes, a marine biologist at James Cook University who led the surveys of the coral die-off. “This region escaped with minor damage in two earlier bleaching events in 1998 and 2002, but this time around it has been badly affected.” Damage to the southern two-thirds of the reef, however, was far less than expected, the scientists reported.

In Slovenia, Drinking Water
Now Protected as a Constitutional Right
Slovenia has amended its constitution to make access to drinking water a human right protected under national law — the first European Union
member state to do so. The amendment, which turns management of water resources over to the federal government as a public good supplied as a nonprofit service, was approved by the Slovenian parliament earlier this month by a 64-0 vote. Lawmakers who opposed the change abstained from the vote rather than voting no, arguing it was unnecessary and a publicity stunt, the Associated Press
reported. Slovenia joins 15 other countries that have incorporated the right to water in their constitutions, according to the Agence France-Presse news agency
. Prime Minister Miro Cerar, who previously called water “the 21st century’s liquid gold,” said that “being able to drink tap water around Slovenia… is a huge privilege that we must preserve for us and generations after us.”

Trump Will Scrap NASA
Climate Research, Senior Adviser Says
NASA’s world-renowned research into climate change will be eliminated
under a Donald J. Trump administration, with some of the space agency’s climate work being transferred to other parts of the U.S. government, according to Robert Walker, Trump’s senior adviser on NASA. Walker said NASA’s chief function will be space exploration and that there will be no need for it to conduct what he has called “politically correct environmental monitoring.” He added, “Mr. Trump’s decisions will be based upon solid science, not politicized science.” NASA, a global leader in monitoring climate change using satellites and other technologies, has a $2 billion earth sciences budget. Walker, a former Congressman, falsely claimed that only half of the world’s climate scientists believe that human activity is driving climate change. Trump said on Tuesday that he has an “open mind” about climate change
and is re-evaluating his pledge to withdraw U.S. support for the Paris climate accords.

Freakishly Warm Weather
Is Preventing Sea Ice Formation in Arctic
Scientists are watching with growing alarm as exceptionally warm air and ocean temperatures are effectively holding winter at bay
throughout much of the Arctic, leading to record low sea ice conditions. Researchers in the U.S., Britain, and Denmark say that air temperatures over much of the Arctic Ocean have been about 10 to 20 degrees C (18 to 36 F) above normal this fall, while sea temperatures have been nearly 4 C (7 F) higher than usual in October and November. As a result, sea ice simply isn’t forming in much of the Arctic basin, which further heats up the atmosphere and ocean since dark, open water absorbs far more solar radiation than the reflective white surface of ice and snow. Jennifer Francis of Rutgers University said the region’s temperatures are now “literally off the charts.” Danish satellite remote sensing expert Rasmus Tonboe said the situation in the Arctic is both “surprising and alarming” because sea ice is disappearing faster than climate models had forecast.

Canada to Phase Out
Nearly All Coal-Fired Electricity by 2030
Canada’s Environment Minister, Catherine McKenna, has announced that the country will eliminate virtually all coal-fired power plants
by 2030, which would mean that 90 percent of Canada's electricity would come from carbon-free sources of energy by that time. Speaking to reporters in Ottawa, McKenna said that four provinces still burn coal for electricity — Alberta, Saskatchewan, Nova Scotia, and New Brunswick. They will either phase out coal use or will be allowed to temporarily keep some coal-fired power plants open if equivalent CO2 emissions reductions are achieved in other sectors, McKenna said. Prime Minister Justin Trudeau, whose Liberal Party took power a year ago, ran on a platform of reducing carbon emissions and embracing renewable energy. Roughly 60 percent of Canada’s electricity is generated using hydropower, and analysts predicted that the Liberal government’s announcement Monday will stimulate the development of wind, solar, and other renewable forms of energy.

Paris agreement, saying that the world has “an urgent duty” to respond to global warming. In the joint statement, known as the Marrakech Action Proclamation
, delegates pledged to stand with nations hit hardest by climate change, reduce emissions to meet a 1.5 degree C temperature goal, and mobilize $100 billion for resiliency work. “We welcome the Paris Agreement, its rapid entry into force, with its ambitious goals… in the light of different national circumstances,” the announcement said, “and we affirm our commitment to its full implementation.” Also this week, 47 countries on the front lines of climate change, including Bangladesh, Ethiopia, and Costa Rica, pledged to go 100 percent renewable and carbon neutral
in coming decades to “help trigger increased commitments from all countries” to reduce greenhouse gases.

"Failure to build a low-carbon economy puts American prosperity at risk,” the group said. “But the right action now will create jobs and boost U.S. competitiveness. We pledge to do our part, in our own operations and beyond.” The statement, presented at United Nations climate meetings
in Marrakesh, Morocco this week, was addressed to U.S. President-elect Donald Trump, U.S. President Barack Obama, Congress, and world leaders. Signatories include major conglomerates such as General Mills, Hewlett-Packard, Hilton, Nike, Kellogg, Unilever, Starbucks, and DuPont, as well as more than 50 other companies and investors with annual revenues exceeding $100 million.
Interview: Are Trees Sentient?
Certainly, Says German Forester
In his bestselling book, The Hidden Life of Trees
, German forester Peter Wohlleben argues
that to save the world’s forests from climate change and other threats we must first recognize that trees are “wonderful beings” with innate adaptability, intelligence, and the capacity to communicate with — and heal — other trees. In an interview with Yale Environment 360
, Wohlleben discusses how trees live in families, have an inborn memory of events like previous droughts, and possess the capacity to make decisions and fight off predators. Wohlleben has been criticized for anthropomorphizing trees, but he maintains that to succeed in preserving our forests in a rapidly warming world, we must start to look at trees in an entirely different light.

For Third Year in a Row, Carbon
Emissions Flat as Global Economy Grows
Global carbon emissions from fossil fuels stayed flat in 2015 and are projected to increase by only 0.2 percent in 2016 — marking three years in a row that emissions have been decoupled from global economic growth, according to a new analysis
by scientists at the University of East Anglia and the Global Carbon Project
. The three-year slowdown is largely due to China’s declining coal usage, the study said, which helped the country reduce emissions 0.7 percent in 2015 and a projected 0.5 percent in 2016. But the scientists warned that emissions simply staying flat is not sufficient to combat climate change. “This third year of almost no growth in emissions is unprecedented at a time of strong economic growth… but it is not enough,” Corinne Le Quéré, a climate scientist at the University of East Anglia who led the data analysis, said in a statement. “Global emissions now need to decrease rapidly, not just stop growing.”

By the end of 2016, 16 out of 17 hottest years on record will have been in this century, with 1998 as the outlier, the WMO said. Warming in Arctic regions has been particularly extreme this year, with temperatures in parts of Arctic Russia soaring to 6 degrees C to 7 degrees C (10.8-12.6 degrees F) above the long-term average. Many others parts of the Arctic have experienced temperatures 3 degrees C above average.

Climate change has already impacted nearly every aspect of life on earth, according to a new study
in the journal Science

Warming global temperatures have altered everything from entire ecosystems down to the individual genes of species. Some 80 percent of key ecological processes examined by the scientists show signs of change and distress. The disruptions could lead to unpredictable fisheries yields, reduced agricultural productivity, worsening pests and disease outbreaks, and “point toward an increasingly unpredictable future for humans,” the authors wrote. "There is now clear evidence that, with only a ~1 degree C of warming globally, very major impacts are already being felt," said lead author Brett Scheffers
, an ecologist at the University of Florida. "Species' physiology and physical features such as body size are changing, species are rapidly moving to keep track of suitable climate space, and there are now signs of entire ecosystems under stress."

A New Initiative to Study
The Microbiome of Sub-Saharan Africa
Scientists have begun the first large-scale survey of microbial life in sub-Saharan Africa, analyzing 1,000 Ziploc bags of dirt from 10 countries, the journal Nature reported
. The three-year initiative, funded by the U.S. Agency for International Development (USAID), hopes to improve understanding of Africa’s diverse microbial biome in an effort to stave off the worst climate change impacts and improve agricultural practices. The project is being led by ecologist Dan Cowan at the University of Pretoria and will involve sampling soils in Namibia, Botswana, Zimbabwe, Mozambique, Zambia, Kenya, Ethiopia, Côte d’Ivoire, Nigeria, and South Africa. The scientists will first analyze DNA to identify bacteria in the soils before looking into soil fungi in the next phase of the initiative.

potentially threatening its drinking water and sacred sites. In many ways, the battle over the Dakota Access Pipeline is a traditional fight over Native American land rights. But as indigenous rights expert Kyle Powys Whyte sees it, the demonstration also points to the important role tribes have played in opposing fossil fuel energy projects in recent years. “Almost everywhere you go, tribes have taken direct action to protect their health and their cultures and their economies from the threats, as well as the false promises of, extractive industries,” he says. In an interview with Yale Environment 360

The birds weren’t sick, but were in an “advanced state of starvation,” National Geographic reported
. While the deaths are alarming, scientists are also concerned about them being a harbinger of bad news for other marine species in the northern Pacific Ocean. Record-warm water temperatures in the region earlier this year may have shifted or reduced critical ocean food sources — small fish and zooplankton called copepods — affecting not only the puffins, but also dozens of other marine species, from seals to salmon to crab. “Clearly something very weird is going on,” said Julia Parrish, a biologist at the University of Washington. “It is basically every year now we’re getting some huge mass-mortality event… And the forage fish that everything depends on are taking it in the shorts.”

Even With Paris Pledges, World
Could Warm As Much as 3.4 Degrees C By 2100
Global temperatures could rise as much as 3.4 degrees C (6.1 degrees F) this century even if nations achieve the greenhouse gas reduction targets set forth in the Paris climate agreement, according to a new report
from the United Nations Environment Program (UNEP). Emissions for 2030 are projected to be 54 billion to 56 billion tons of carbon dioxide, which is nearly 25 percent — or 12 billion to 14 billion tons of CO2 — higher than levels needed to hold global warming to 2 degrees C by 2100. The new UNEP report comes just one day before the Paris climate agreement officially enters into force, and a few days before the next UN global climate conference in Marrakesh, Morocco. “The world must urgently and dramatically increase its ambition to… have any chance of minimizing dangerous climate change,” the UNEP said

Diapers Made from Jellyfish?
Company Utilizes Super-Absorbent Qualities
Jellyfish populations around the world are on the rise, driven by rising ocean temperatures, increasing acidity, and overfishing.

But a start-up company in Israel has found a way to harness these booming jellyfish populations, using them to create biodegradable diapers and feminine hygiene products, The Guardian reported
. The company, Cine’al
, was created by University of Tel Aviv scientist Shachar Richter, who discovered that the flesh of jellyfish can absorb large quantities of liquids. By breaking down jellyfish bodies and adding antibacterial nanoparticles, Richter and his company have created a super-absorbent material they call “hydromash” that can be used in medical bandages, tampons, pads, and diapers. Americans currently throw away an estimated 40 million diapers every day, each of which can take years or decades to break down in landfill. The hydromash material takes only 30 days to biodegrade, the company says. Cine’al plans to have products ready for market in the next 18 months, according to The Guardian

. Some snakes, including pythons and boas, still have tiny leg bones inside their bodies, remnants of this evolutionary history; but most species lost their legs starting about100 million years ago. The scientists traced the mutation back to a docking site for proteins, known as an enhancer, situated in front of the Sonic hedgehog
gene, which controls limb development. They found that the enhancer is simply switched off, not broken. When the missing DNA was fixed and the modified enhancer was put in mice, they grew legs like normal
The Moth Snowstorm: Finding
True Value in Nature’s Riches
It is the blizzard of moths that Michael McCarthy remembers most vividly. As a boy, his family would take summer nighttime drives to the English coast,
and the car headlights and windshield would soon be so splattered with moths they would have to stop to clean them off. “That phenomenon has gone,” says McCarthy. “It’s disappeared because there has been a horrendous crash in moth numbers in the U.K.” His recent book, The Moth Snowstorm: Nature and Joy
, offers a defense of the natural world rooted in the joy and spiritual nourishment it provides. In an interview with Yale Environment 360
, McCarthy, a British journalist, talks about the loss of wildlife; how the decline in species abundance, as opposed to extinctions, is overlooked; and why he thinks putting a monetary value on so-called ecosystem services is too limiting. “You can say mangrove swamps are worth so many billion dollars,” he says. “But what about birdsong? How much is birdsong worth?”
