06 Dec 2016: 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 next year.

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.”

30 Nov 2016: 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.

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.

23 Nov 2016: 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.

21 Nov 2016: 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.

11 Nov 2016: Just 1 Degree C of Warming Has
Altered Nearly Every Aspect of Life on Earth

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."

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, Powys Whyte talks about the long history of coal and oil and gas development on native lands and why Standing Rock has become a lightning rod for opposition to fossil fuels.

09 Nov 2016: Could Dying Puffins in the Bering
Sea Spell Trouble for Other Marine Life?

Starting in mid-October, hundreds of tufted puffins began washing up dead on islands in the Bering Sea off the coast of Alaska.

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.”

04 Nov 2016: Scientists Attempt to
Create 3D Models of All Life on Earth

Scientists at the University of Massachusetts, Amherst have launched a new initiative to create 3D models of all of the world’s living organisms.

Biologist Duncan Irschick invented a 30-camera array, the “Beastcam,” that captures high-resolution, full-color images of an animal’s body from all different angles. Using those photographs, Irschick and his colleagues have already created 3D models of sharks, scorpions, toads, and lizards. They plan to focus next on capturing frogs and sea turtles. The initiative, known as Digital Life, is partnering with scientists, zoos, and non-profits to gain access to species, including those that are endangered or threatened, and providing 3D models at no cost via an open access website. “Digitally preserving the heritage of life on Earth is especially important given the rapid decline of many species,” said Irschick. “This technology can recreate organisms in a way that has never been done before.”

That close proximity puts these people at increased risk of cancer, heart disease, and respiratory problems from natural gas leaking from the wells, said the Wilderness Society, which together with Earthworks helped create the tool. In Wyoming, for example, 15,869 oil and gas facilities operate on public land, and some 4,000 people live within a half-mile of them — the range that airborne pollutants from wells, such as benzene, can easily travel. The mapping tool is being released at a time when scientists, environmental groups, and policymakers are ramping up calls to reduce and regulate natural gas leaks from drilling and storage sites.

Action Fails to Sway Many Americans

A direct call to action by the Pope has apparently failed to inspire people to be concerned about climate change, according to a new national survey by

public policy researchers at the University of Pennsylvania. Last year, Pope Francis release a 200-page papal letter entitled “Laudato Si,” or “Be Praised,” that urged 1.1 billion Catholics to address climate change and live more sustainably. The new survey, published in the journal Climatic Change, found those who had heard of the encyclical — both Catholics and non-Catholics — were no more concerned about global warming than those who hadn’t. Those who knew about the encyclical were also more politically polarized in their acceptance or denial of climate change. The scientists used data from 1,381 20-minute phone interviews one week before the encyclical’s release and two weeks after it was published.

21 Oct 2016: Scientists Report Finding DNA
Mutations That Caused Snakes to Lose Legs

creation of modern day snakes, according to two studies published week. The findings were discovered by two independent teams of researchers, which reported their results separately in the journals Current Biology and Cell. 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.

19 Oct 2016: Can We Turn CO2 into a Useable
Fuel? Scientists Say They Have Found a Way

Scientists at the Oak Ridge National Laboratory in Tennessee report that they have found a way to convert carbon dioxide into ethanol, a usable fuel. The team used a spiky nanotechnology-based catalyst made out of carbon, copper, and nitrogen. When they applied voltage to the catalyst, CO2 dissolved in water turned into ethanol, with a yield of 63 percent. “We discovered somewhat by accident that this material works,” said Adam Rondinone, the Oak Ridge scientist that led the research. Because the materials are relatively cheap and the reaction can happen at room temperature, the researchers say the technique could be scaled up to store renewable energy as ethanol, for example, or to convert CO2 emissions into fuel. Finding new ways to use CO2 “in order to displace a fossil feedstock,” the scientists wrote in the study, “is an appropriate intermediate step towards a carbon-free future.”

NASA’s temperature data is collected by 6,300 meteorological stations scattered across the globe, a buoy-based data system in the oceans, and research centers on Antarctica.

14 Oct 2016: Is There Too Much Emphasis
Being Placed on Carbon Capture Technology?

The world is placing too much credence on being able to combat climate change by pulling carbon dioxide from the atmosphere, a process known as “air capture,” according to an article in the journal Science this week. “Negative-emission technologies are not an insurance policy, but rather an unjust and high-stakes gamble,” wrote the article’s authors, Kevin Anderson, a climate scientist at the University of Manchester in the U.K, and Glen Peters, a scientist at CICERO, a climate research organization in Norway. “There is a real risk they will be unable to deliver on the scale of their promise,” and assuming otherwise is “a moral hazard par excellence,” they wrote. Carbon capture technologies are a key component of the Paris climate agreement, with many of the modeling scenarios assuming the technology will be operating on a large scale later this century, reported Climate Central.

The seven species, which include Hylaeus anthracinus, H. assimulans, H. facilis, H. hilaris, H. kuakea, H. longiceps, and H. mana, pollinate some of Hawaii’s most threatened plants and live in a variety of Hawaiian ecosystems, from the coast, to dry forests, to subalpine shrublands, reported Mongabay. Scientists and conservation groups had been petitioning FWS to protect the bees for more than five years, citing habitat degradation, predation, and rapidly declining population numbers. The federal agency released the new rule late last month. The rule also gave protection to three additional animal species and 39 plant species, all from Hawaii.

10 Oct 2016: Trump Proclaims at Debate
That ‘Coal Will Last for 1,000 Years’ in U.S.

At the second 2016 U.S. presidential debate, Democrat Hillary Clinton and Republican Donald Trump clashed over energy policy and climate change, with Trump

saying the energy industry is “under siege” from Obama administration regulations and vowing that “clean coal” will continue to power the U.S. for a thousand years. While both pledged to help beleaguered coal miners, Trump doubled down on his support for fossil fuel production while Clinton said the U.S. must gradually decouple its economy from coal, oil, and natural gas. “I support moving towards more clean, renewable energy as quickly as we can because I think we can be the 21st-century clean-energy superpower and create millions of new jobs and businesses,” she said.

06 Oct 2016: Methane Emissions From Fossil
Fuels Much Higher Than Previously Thought

Methane emissions from global fossil fuel production are up to 60 percent higher than previously estimated, according to a new study in the journal Nature by the National Oceanic and Atmospheric Administration and several universities. Combined, methane emissions from oil and gas production and natural geological leakage are up to 110 percent greater than previously estimated. The upward revision shows that the fossil fuel industry is responsible for 25 percent of total global methane emissions, or up to 165 million tons of the 623 million tons emitted from all sources. The study comes at a time when companies are working to reduce methane leaks from extraction facilities and pipelines, with some success. The scientists found leak rates have declined from 8 percent to 2 percent over the past 30 years. Increased natural gas production, however, has negated these improvements.

Thousands of Plastic Fibers When Washed

A single load of laundry can shed more than 700,000 microscopic plastic fibers into water systems, according to a recent study in the journal Marine Pollution Bulletin.

The study looked at the breakdown of polyester, acrylic, and polyester-cotton fabrics washed in 86-104 degree Fahrenheit water with various detergents. It found that a 13-pound load of polyester-cotton laundry shed an estimated 137,951 plastic fibers, a load of polyester clothing 496,030 fibers, and acrylic fabric 728,789 fibers. Microplastic particles in waterways are often mistaken for food and eaten by marine life, with various health impacts. The research was conducted by scientists at Plymouth University in England.

according to a new report by the scientific agency, Natural Resources Canada. The number of large forest fires in the country is also expected to increase 1.5-fold over the same period due to milder, drier conditions, the report said. In 2015, 7,068 wildfires burned about 3.9 million hectares of Canadian forest. The annual report, The State of Canada’s Forests, noted that even if the world manages to limit global warming to an average 2 degrees Celsius, Canada could still experience a temperature rise of 4 degrees C by 2100. The report said such warmer conditions will change the species composition, size, and age distribution of Canada’s forests, a natural resource that generated more than $22 billion in gross domestic product for the country in 2015.

27 Sep 2016: Could California’s Gridlock
Generate Electricity for the Grid?

California is testing whether its heavy traffic can produce not just emissions and air pollution, but electricity.

The state’s Energy Commission says it will spend $2 million to examine the potential of using piezoelectric crystals embedded under asphalt as a way to send the energy created by moving cars to the grid. The crystals generate energy when compressed by the weight of moving cars, but tests of the technology at larger scales have failed or been canceled in Tokyo, Italy, and Israel, according to the Associated Press. California, therefore, “needs to figure out whether it can produce high returns without costing too much,” the AP writes. If successful, the technology could help the state reach its goal to generate 50 percent of its electricity from renewable sources by 2030. California is expected to hit a 25 percent renewables target by the end of this year.

The cause of the collapse, according to a recent study in the journal Science Advances, is not alien plants or predators, but rather warming temperatures that have enabled non-native mosquitoes carrying deadly avian malaria to invade the birds’ high-elevation strongholds. In an interview with Yale Environment 360, Eben Paxton, an avian ecologist with the U.S. Geological Survey and the study’s lead author, says his group’s research showed that the mosquitoes moved into the Alakai Plateau over the last decade, infecting the birds and pushing their populations to a tipping point. He cites a number of approaches for eradicating the mosquitoes, including releasing irradiated infertile males and using genetically modified mosquitoes. “The way that we view Kauai,” he says, “is that it's an early warning system for the rest of the islands.”

The scientists said land use changes, habitat loss, and climate change were main factors behind the long-term population declines. It also found collisions with power lines, buildings, and vehicles caused 900 million bird deaths each year, and domestic and feral cats kill another 2.6 billion.

15 Sep 2016: Obama Announces First
Marine Protected Area off U.S. East Coast

President Obama is creating a 4,913-square-mile marine monument off the New England coast, adding to a long list of marine protected areas established in recent years by the Obama and Bush administrations. The Northeast Canyons and Seamounts Marine National Monument, 130 miles southeast of Cape Cod, contains massive undersea canyons and towering seamounts and is the first fully protected federal marine reserve off the eastern seaboard. The area is home to deep-sea corals, sharks, deep-diving marine mammals, whales, and sea turtles, and is a rich fishing ground. The fishing industry objected to the creation of the marine monument, arguing that existing fisheries management laws were sufficient to protect the area. Under the new designation, commercial fishing will be phased out over seven years. Obama has also recently created massive marine reserves off Hawaii and the U.S. West Coast, and today a quarter of U.S. waters are under strong federal protection.

The research, conducted by scientists at the University of Nebraska-Lincoln and the University of Minnesota, was recently published in the journal Scientific Reports.

"If her ability to lay eggs is reduced, that is a subtle effect that isn't (immediately) noticeable, but translates to really dramatic consequences for the colony." The scientists also found colonies exposed to imidacloprid, a type of neonicotinoids, collected and stored less pollen than insecticide-free colonies, and removed just 74 percent of mite-infested or diseased pupae that can infect the entire hive, compared to 95 percent removal by unexposed bees.

08 Sep 2016: The World Has Lost 10 Percent
Of Its Wilderness Over Last Two Decades

The world has lost one-tenth of its wilderness — an area twice the size of Alaska — over the last 20 years, scientists reported this week in the journal Current Biology.

Wilderness loss since the early 1990s.
The hardest hit areas have been the Amazon and Central Africa, which have been plagued by rampant and unregulated logging and other industrial activities in recent decades. The scientists found there are 11.6 million square miles of wilderness remaining on earth, largely located in North America, North Asia, North Africa, and Australia. "The amount of wilderness loss in just two decades is staggering and very saddening," said lead author of the study James Watson, a biologist at the University of Queensland and the Wildlife Conservation Society. "You cannot restore wilderness. Once it is gone, the ecological process that underpin these ecosystems are gone, and it never comes back to the state it was. The only option is to proactively protect what is left."

– in other words, she found, they “talk” to each other. Since then, Simard, now at the University of British Columbia, has pioneered further research into how trees converse, including how these fungal filigrees help trees send warning signals about environmental change, search for kin, and transfer their nutrients to neighboring plants before they die. Simard is now focused on understanding how these vital communication systems, which she compares to neural networks in human brains, could be disrupted by environmental threats, such as climate change, pine beetle infestations, and logging. “These networks will go on,” she told Yale Environment 360. “Whether they're beneficial to native plant species, or exotics, or invader weeds and so on, that remains to be seen.”
