A Bay in Denmark May
Hold The Global Record for Carbon Storage
Danish scientists say that a sheltered bay in southern Denmark may hold the world record for carbon storage
Thurøbund Bay in Southern Denmark.
because of its abundant seagrass meadows, which sequester carbon extremely efficiently. Reporting in the journal Biogeosciences
, the scientists said that CO2 absorption by eelgrass in Thurøbund Bay has resulted in the bay storing 27,000 grams of carbon per square meter, more than twice as much as other efficient carbon-storing ecosystems worldwide. A key reason for Thurøbund’s impressive carbon storage is that once seagrasses die in its sheltered waters, they are buried in the bay’s sediments, locking up the carbon. By contrast, many of the nine other Baltic Sea sites studied by the scientists were in exposed coastal areas, which means that dead grasses are carried out to sea and often not buried in sediment. The importance of “blue carbon” storage in coastal waters is gaining increasing attention, with international programs now paying local residents to replant
sea grasses, mangroves, and other shallow-water plants.

Affluent Chinese Families
Now Have Similar CO2 Footprint as Europe
The rising numbers of middle and upper class Chinese now generate carbon emissions that are beginning to rival those of Europeans
, according to a new study. An Austrian researcher calculated that the 300 million Chinese who now make up the country’s increasingly well-off urban population annually generate 2 to 6.4 tons of carbon dioxide per capita. The wealthiest Chinese now have a carbon footprint that approaches residents of the European Union, who have an annual carbon footprint of 6.7 tons per capita. Because many of its 1.3 billion citizens still live in poverty, China overall only produces 1.7 tons of CO2 per capita, far below the average American’s carbon footprint of 10.4 tons per capita. Reporting in Nature Climate Change
, researcher Dominik Wiedenhofer said rising Chinese emissions underscore that all nations must focus on “decoupling” carbon emissions from affluent living standards.

France Opens World’s
First Solar Panel Road in Normandy
France has opened what it says is the world’s first solar-paneled road
— a one-kilometer stretch that is expected to power street lighting
A new solar panel road in Normandy, France.
in the village of Tourouvre-au-Perche in Normandy. The motorway, which is covered in 30,000 square feet of solar panels, cost $5.2 million to build and will be traveled on by 2,000 cars each day. The company that installed it, French engineering firm Colas, says it has about 100 other solar-paneled road projects underway, both in France and abroad. Critics of the project, however, argue that the Normandy road is not a good investment. Normandy gets only 44 days of strong sunshine each year, according to The Guardian
. Solar roadways have been proven less efficient at generating electricity than panels installed on rooftops. France’s environment minister, Ségolène Royal, has said she would like one kilometer in every 1,000 kilometers of French highway to be made of solar panels.

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.”

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.”

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.”
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.

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
A bearded seal near Monaco Glacier, Svalbard.
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."

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
. 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?”

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

they release into the atmosphere. Collaborating with international seed company DLF, the scientists are working to create a “super grass” that is easier for cows to digest, thereby reducing the amount of gas that builds up in their stomachs, several media outlets reported
. Global emissions of methane — which is roughly 30 times more potent than carbon dioxide over a 100-year period — have been on the rise since the 1980s. Livestock, specifically cows, are thought to release an estimated 90 million tons of methane into the atmosphere annually. The new, nearly $2 million research collaboration between the University of Aarhus in Denmark and DLF hopes to develop the new grass by 2024, at the latest.

built on the premises, according to a draft directive from the European Union. The new rule, to be published by the end of the year, is meant to help nations curb transportation-related greenhouse gas emissions, cut air pollution, and reach climate targets. Norway and the Netherlands, for example, both plan to phase out diesel engine vehicles by 2025, according to The Guardian
. “This kind of market stimulus is not just positive, it is mandatory if we want to see a massive rollout of electric vehicles in the near future,” said Guillaume Berthier, head of electric car sales for automaker Renault. “The question of how you recharge your car when you live in an apartment within a city is a very important one.”

Scotland to Generate Some of
World’s First Kite-Driven Power in 2017
The United Kingdom will begin harnessing energy from kites flying 450 meters above ground as early as next year. Developed by UK-based Kite Power Solutions
A kite-powered wind energy generator.
the system is composed of two 40-meter wide kites that rise and fall in tandem, spooling a tether line to turn a turbine. A test site was previously built in Essex
, and a 500-kilowatt system will be built near Stranraer, Scotland on the West Freugh air force station. Because the kites are lighter than wind turbines, they can more easily be built offshore and reach higher altitude winds, which are faster and more consistent. The technology, which companies hope could revolutionize global renewable energy strategies, is also being tested
in Switzerland and Italy, among other countries.

Scientists Find Clothing Sheds
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
. Many of these tiny plastic particles make it through sewage treatment plants and enter aquatic ecosystems such as rivers, lakes, wetlands, and oceans. 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.

Newly Discovered Fossils Break
Record, Dating Back 3.7 Billion Years Ago
Geologists have found fossils in Greenland dating back 3.7 billion years — the oldest evidence of life on earth discovered to date. The layers of stromatolites, which are made up of fossilized microbes,

were found in the world’s oldest sedimentary rocks, the Isua supracrustal belt along the edge of the Greenland ice cap. They predate the previous fossil record holder by roughly 220 million years, according to Allen Nutman
, a geologist at the University of Wollongong in Australia and lead author of the new findings, published in the journal Nature
this week. The fossils “indicate that as long as 3.7 billion years ago, microbial life was already diverse,” said Nutman. “This diversity shows that life emerged within the first few hundred millions years of Earth’s existence, which is in keeping with biologists’ calculations showing the great antiquity of life’s genetic code.”

Ragweed Allergies Could Double
In Europe as Global Temperatures Rise
The number of people suffering from ragweed allergies in Europe could more than double by mid-century due to climate change, according to a new study published in the journal
Environmental Health Prospectives
Ragweed (Ambrosia artemisiifolia)
. Warming global temperatures, the research found, will help increase the distribution of ragweed (Ambrosia artemisiifolia
) by making more areas of the continent suitable for its growth. Higher temperatures will also make growing seasons longer and increase pollen concentration in the air. Ragweed allergies, popularly known as hay fever, could impact 77 million people in Europe by 2041 to 2060, up from 33 million today, said the new study, led by scientists at the University of East Anglia. Allergies cost Europe $62 billion a year in lost productivity and are responsible for four million sick days worldwide, according to the news site Quartz

Study Shows Humans Learning
To Use Natural Resources More Efficiently
Humanity’s influence on the natural world is widespread, but a new study published in the journal Nature Communications
finds promising signs that we are slowly learning to live in a more sustainable way. The study found that between 1993 and 2009, the global population grew 23 percent and the global economy grew 153 percent. Meanwhile, the global human footprint grew only 9 percent over the same period. "Seeing that our impacts have expanded at a rate that is slower than the rate of economic and population growth is encouraging," said lead author Oscar Venter, an ecologist at the University of Northern British Columbia. "It means we are becoming more efficient in how we use natural resources." The study authors warned, however, that even with the good news, human activity affects 75 percent of the planet’s surface and remains “perversely intense, widespread, and rapidly intensifying in places with high biodiversity.”

) — a densely branched, slow-growing tree —
Europe's oldest tree, a Bosnian pine, in Greece.
was found in northern Greece, high in the Pindus Mountains. A team of Swedish, German, and U.S. scientists extracted a core of the tree’s one-meter thick trunk, and counted the rings that mark its annual growth—a dating technique known as dendrochronology. They found the tree started its life in 941. "I am impressed, in the context of Western civilization, all the human history that has surrounded this tree, all the empires – the Byzantine, the Ottoman – all the people living in this region,” said University of Stockholm dendrochronologist Paul Krusic, who led the research. “So many things could have led to its demise. Fortunately, this forest has been basically untouched for over a thousand years."

July measured 1.27 degrees F above the 1951-1980 average, and 0.2 degrees F above July 2015, the previous record. This year has seen a streak of record-breaking monthly temperatures, fueled by a strong El Niño and climate change. Gavin Schmidt, the director of NASA’s Goddard Institute of Space Studies, said on Twitter
that 2016 now has a 99 percent chance of being the hottest year on record. If that happens, it will be the third such year in a row, reported Climate Central

Researchers Discover Ocean
Crust Dating Back 340 Million Years
Scientists have found what they believe is the world’s oldest piece of ocean floor — dating to more than 300 million years ago — in the Mediterranean Sea.
The Herodotus Basin in the eastern Mediterranean Sea.
Because shifting tectonic plates continuously drag seafloor rock into the earth’s mantle, most ocean crust is younger than 200 million years. The new discovery, found in the Herodotus Basin between Cyprus, Crete, and Egypt, indicates that area of seafloor is likely a remnant of the Tethys Ocean, which existed at the time of the Pangaea supercontinent, according to a new study in the journal Nature Geoscience
. To determine the rock’s age, scientists dragged a magnetometer
behind a research vessel on four different trips, measuring the magnetic signals in the underlying seafloor, and comparing them to signals of the African continental plate and the earth’s shifting magnetic alignment over millions of years. They determined that the oceanic crust in the Herodotus Basin is between 315 and 365 million years old.

Ukraine is looking for investors for a 1-gigawatt solar farm in the 1,000-square-mile exclusion zone, where radiation levels remain too high for farming or forestry, reported Bloomberg
. The project would cost $1.1 billion and transform Chernobyl into one of world’s largest solar installations. Government officials say that two U.S. investment firms and four Canadian energy companies have expressed interest in the project. The European Bank for Reconstruction & Development is also considering financing the solar farm. “The Chernobyl site has really good potential for renewable energy,” Ukraine’s environment minister Ostap Semerak said

Global Economy Has Reduced
Its Energy Intensity By One-Third Since 1990
The global economy is becoming less energy intensive
, using fewer fossil fuels to power productivity and economic growth, according to new data from the U.S. Department of Energy.
Rooftop solar panels
Global energy intensity — a measure of energy consumption per unit of gross domestic product (GDP) — has decreased nearly one-third since 1990, the agency said. The U.S., for example, burned 5,900 British thermal units per dollar of GDP
in 2015, compared to 6,600 BTUs in 2010. China burned 7,200 BTUs per dollar in 2015 versus 8,300 BTUs in 2010. The Department of Energy says the decrease is the result of the growth in low-carbon energy sources, such as wind and solar, and improved energy efficiency. “This is excellent news,” Penn State University climatologist Michael Mann told Climate Central
. “The dramatic drop we are seeing in global energy intensity is a direct indication that energy efficiency measures are having a very direct impact on global carbon emissions.”

Global Temperatures Continue
To Shatter Heat and Arctic Ice Records
June marked the 14th consecutive month of record-breaking heat, with global temperatures measuring 1.62 degrees F above the 20th-century average, NASA and the National Oceanic and Atmospheric Administration announced this week
Global 2016 temperatures.
The first half of 2016 was 1.89 degrees F above last century’s average, breaking the previous January-June record set in 2015 of 0.36 degrees F above average. “2016 has really blown  out of the water,” Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, told reporters
. Five of the first six months of this year have also set records for the smallest Arctic sea ice extent since satellite records began in 1979. Scientists said the recent record-breaking heat could be partly attributed to last year’s strong El Nino, but not entirely. “While the El Niño event… this winter gave a boost to global temperatures from October onwards, it is the underlying trend which is producing these record numbers,” Schmidt said

Climate Change Has Shifted
The World’s Cloud Cover Over Past 30 Years
Warming global temperatures have altered the distribution of clouds across the Earth in recent decades, according to new research published in the journal Nature
Global cloud cover.
Mid-latitude storm clouds have shifted polewards, dry subtropical zones have expanded in size, and the tops of clouds have gotten higher as a result of a warmer troposphere and cooler stratosphere, according to the study, which relied on satellite images taken between 1983 and 2009. Researchers said these shifts in cloud cover could further exacerbate climate change. As cloud systems shift toward the poles, where there’s less solar radiation, more sunlight will reach the Earth’s surface near the equator, boosting temperatures. Also, taller, thicker clouds trap more heat. “We now have a thicker blanket, which is also a warming effect,” said Joel Norris
, a climate scientist at the Scripps Institution of Oceanography in San Diego who helped lead the study.

Hundreds of Deaths in 2003
Heat Wave Linked to Climate Change
A new study suggests that human-caused climate change could be responsible for a significant portion of the 70,000 deaths that occurred during the record-breaking 2003 European heat wave. The research, published in the journal Environmental Research Letters
, combined climate modeling with health data for hundreds of fatalities that summer. Climate change, the study found, increased the likelihood of heat-related losses by nearly 70 percent in Paris and 20 percent in London. Out of 735 heat-related deaths in Paris, 506 were attributable to global warming, as were 64 out of 315 deaths in London. "Until recently, whenever we talked about climate change we talked about the globally averaged increase in temperature of 1 degree and people just don't really know or frankly care about that," lead study author and Oxford University scientist Daniel Mitchell told InsideClimate News
. "But now… people can really start to understand that these are impacts we're seeing now, not in the future."

Paris Bans All Pre-1997
Cars During Weekdays to Fight Pollution
Starting this month, Paris is banning all cars built before 1997 from driving within city limits Monday through Friday in an effort to lower air pollution levels.
Commuter traffic in Paris.
Paris has been struggling with smog for years and its pollution levels have briefly topped those in Beijing. Similar to Mexico City and New Delhi
, Paris banned even- and odd-numbered license plates on alternating days to fight smog earlier this year. It has also championed cleaner transit options, such as bike- and electric car-sharing programs. Not everyone is enthused, however: The French consumer group 40 Million Drivers said the ban could impact up to 500,000 vehicle owners in and around Paris, particularly low-income families. "When you have an old car in France, it's because you don't have the money to buy a new one," Pierre Chasseray, the executive director of 40 Million Drivers, told NPR
. "Public transport is a solution, but it's not the solution for everybody."

The new group — a merger of the European Union-based Covenant of Mayors and the United Nations-backed Compact of Mayors — represents a combined 600 million people in 119 countries. The initiative aims to set city-based CO2 emissions cuts, build sustainable communities, and foster the sharing of resiliency policies and technologies. “Cities are key to solving the climate change challenge,” former New York Mayor Michael Bloomberg and Maroš Šefčovič, vice-president of the European Commission, wrote in The Guardian
. “They account for most of the world’s carbon emissions, and mayors often have control over the largest sources. Cities can also act quickly to confront climate change, without the political and bureaucratic hurdles that often hold back national governments.”

Scientists Discover Contagious
Cancer in More Species of Shellfish
Last year, scientists discovered a type of contagious cancer in soft-shell clams in which free-floating cells transmitted the disease from one animal to another.
Now, a team of Columbia University researchers is reporting that contagious cancers in the ocean may be more common than previously thought
and can not only jump from animal to animal, but across species. According to the new study published in Nature, the leukemia-like cancer, known as disseminated neoplasia, has been found in three more species of bivalves: mussels, cockles, and golden carpet shell clams. The cancer cells were genetically distinct from their hosts, indicating they originated elsewhere. Transmissible cancer had previously been found in Tasmanian devils
and dogs, but there’s no indication that humans are at risk. “I would only worry deeply if I was a mollusk,” Stephen P. Goff, a molecular biologist at Columbia University and co-author of the study, told The New York Times
