currently the most heavily trafficked mammal in the world. Pangolins are found across Asia and sub-Saharan Africa, and are sought after for their meat and scales
, the latter of which are believed by some in East Asia to have medicinal purposes. Pangolins are shy, cat-sized mammals that eat ants and termites, and when threatened they curl into a ball rather than defending themselves. Nearly one million pangolins have been trafficked in the past decade, according to National Geographic
. The International Union for the Conservation of Nature (IUCN) has listed all eight species of pangolin as endangered or threatened with extinction.

World’s Coffee Supply
Threatened by Climate Change, Report Says
A new report says that climate change could significantly reduce the amount of suitable land on which to grow coffee
and lead to an increase in outbreaks of diseases that threaten the crop. The report
— released by the Australian non-profit, the Climate Institute — warns that under current emissions scenarios, coffee-growing regions could see a 50 percent drop in the acreage fit to raise coffee plants, which need a precise combination of temperature and precipitation to thrive. Rising temperatures are also likely to lead to an increase in diseases like coffee rust and pests like the coffee berry borer, the report said. Major coffee-producing countries in the “bean belt” — including Colombia, Mexico, Brazil, Ethiopia, and Vietnam — have already become less hospitable because of shifts in weather patterns, the report said. “It’s a severe threat,” said an executive at U.S.-based Peet’s Coffee.

China Leads in Wind Installation,
But Continues to Prioritize Coal in the Grid
China built two wind turbines every hour in 2015, double that of the U.S., according to the International Energy Agency
. The country is installing enough wind to meet all of its new energy demand, more than 30,000 megawatts last year. Despite this promising development, however, the IEA told BBC News
that China is giving coal-fired power plants priority access to the grid over wind, hampering the country’s pledge to get an increasing share of its electricity from renewable energy sources. “The rather rosy statement on wind energy hides the issue that 2015 and the first half of 2016 also saw record new installations of coal,” an IEA spokesman said. “China has now a clear over-supply. In the province of Gansu, 39% of wind energy had to be curtailed (turned off).”

Islamic Leaders Issue Fatwa on
Indonesia’s Slash-and-Burn Agriculture
Indonesia has been plagued by intense smog and smoke in recent years from a growing number of wildfires set to clear land for the production of pulp, paper,

and palm oil. In 2015, the fires — large enough to be visible from space — caused tens of billions of dollars in damage
, grounding hundreds of flights, closing schools, and creating respiratory problems for an estimated 500,000 Indonesians. This week, Indonesia’s highest Islamic council issued a fatwa, a legal religious ruling or decree, discouraging companies and individuals from using slash-and-burn agriculture. The council said any burning that “causes environmental damage… is illegitimate," Reuters reported
. Indonesia has the world’s largest Muslim community — 205 million people — making up 87.2 percent of its population.

Dolphins Speak in Ways Similar
To Human Conversation, Finds New Study
Dolphins communicate in a way very similar to how humans talk, saying up to five complex “words” in a sentence and pausing to listen to each other before speaking, according to a new study
. Researchers at the T. I. Vyazemsky Karadag Scientific Station in Russia observed the conversation
in two Black Sea bottlenose dolphins, known as Yasha and Yana. “The dolphins took turns producing pulse packs [words and phrases] and did not interrupt each other, which gives reason to believe that each of the dolphins listened to the other's pulses before producing its own,” the scientists wrote in the study. “This language exhibits all the design features present in human spoken language, [indicating] a high level of intelligence and consciousness in dolphins.”
For China’s Massive Data Centers,
A Push to Cut Energy and Water Use
China’s 1.37 billion people, many of them fully connected to the Internet, use an enormous amount of energy as they email, search the Web, or stream video.

Indeed, the Chinese government estimates that the country’s data centers alone consume more electricity than all of Hungary and Greece combined. But as Chinese technology and internet businesses look to burnish their environmental credentials and lower costs of operation, many are working to run their massive computing facilities more sustainably. Globally, tech giants such as Microsoft, Google, and Amazon are making rapid progress in this field, as they boost energy efficiency at data centers and seek to completely power their operations using renewable energy.

July Was the Hottest Month on
Record, Continuing Steak of High Temps
July was the world’s hottest month since modern temperature record keeping began in 1880, according to new NASA data released this week.
July 2016 temperatures compared to average.
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
. Fourteen of the 15 hottest years on record have occurred since the start of the 21st century.

July Electric Car Sales in China
Rose by 188 Percent Over Last Year
Chinese consumers bought 34,000 new electric cars in July, a 188 percent jump over the same period last year, according to CleanTechnica
, an energy and technology news organization. The monthly total puts China on track to sell 400,000 electrical vehicles in 2016, accounting for 1.5 percent of the total auto sales market — larger than annual EV sales in Europe, or the U.S., Canada, and Mexico combined. By the end of the year, China is projected to have 700,000 electric cars on its streets; the vast majority of EV sales, 96 percent, are for Chinese-made cars, including from manufacturers BYD Auto, Zhidou, and SAIC Motor. Tesla accounts for just 2 percent of EV sales in the country, and Porsche just 1 percent.

Anthrax Outbreak in Northern
Russia Linked to Rising Global Temperatures
Soaring Arctic temperatures have released anthrax long frozen in the Russian tundra, sickening scores of nomadic herders, including 50 children, and killing one 12-year-old boy, according to news reports
. More than 2,300 reindeer have also died from the disease, known locally as the “Siberian plague.” Anthrax spores can lie dormant in frozen permafrost, animals, and human remains for hundreds of years, and eventually seep into groundwater during a thaw. The last anthrax outbreak in northern Russian happened 75 years ago, in 1941. Temperatures in the Yamal Peninsula, located 1,200 northeast of Moscow, reached 95 degrees F this past month. “Such anomalous heat is rare for Yamal, and that’s probably a manifestation of climate change,” Alexei Kokorin, head of WWF Russia’s climate and energy program, told The Guardian

New Zealand to Eradicate
All Rats, Stoats, and Possums by 2050
New Zealand is launching a $28 million initiative
to eliminate all rats, stoats, and possums from the country by 2050.

The invasive predators — which hitchhiked or were purposely brought to the islands in the 18th and 19th centuries — cost New Zealand’s economy an estimated $13.3 billion a year
by destroying habitat, spreading disease, and killing vulnerable, native species. Invasive predators kill around 25 million native New Zealand birds every year, such as the kiwi and the kakapo, a flightless parrot with a population of just 126 in 2014, according to National Geographic
. The initiative aims to remove rats, possums, and stoats — a member of the weasel family — from 2.5 million acres of land by 2025, and then eradicate the remaining populations using traps or poisoned bait by 2050. If total extermination isn’t possible, the organizers hope the three species can at least be eliminated on the country’s offshore island nature reserves.

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

India Plants Nearly 50 Million
Trees to Fight Air Pollution, Climate Change
India planted 49.3 million trees in just 24 hours earlier this week in an effort to raise awareness of forest conservation, air pollution, and the fight against climate change — shattering the previous world record
of 847,275, set in Pakistan in 2013. Officials said more than 800,000 people in Uttar Pradesh, the country’s most populous state, turned out to help, including students, government officials, and volunteers from nonprofit groups. As part of its climate commitments in Paris last December, India has pledged to increase its forest cover to 235 million acres by 2030. So the government officials has designated more than $6.2 billion for the nation's states to host tree planting drives. “The world has realized that serious efforts are needed to reduce carbon emissions to mitigate the effect of global climate change. Uttar Pradesh has made a beginning in this regard,” the state’s chief minister Akhilesh Yadav 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.

Rare Ancient Bird Wings Found
In Perfect Condition Preserved in Amber
Researchers digging through amber mined in Myanmar have discovered one of the most pristine pairs of ancient bird wings
ever found — tiny, fossilized, feathered appendages belonging to a hummingbird-sized create that lived roughly 99 million years ago. Preserved in amber — clear, fossilized tree resin — the wings belonged to the group Enantiornithes. The preserved wings came from a bird that was much closer in appearance to modern-day birds than other bird species of that era. Researchers have discovered other ancient bird parts in amber, but usually just small fragments of isolated feathers. The pair of wings discovered in Myanmar by a Canadian team of researchers was preserved in minute detail, with hair, feathers, and bones arranged in their original form. The scientists said that even the feathers’ color was still visible. “It gives us all the details we could hope for — it’s the next best thing to having the animal in your hand,” said one scientist.

Cities on Six Continents
Join Forces to Combat Climate Change
Mayors from more than 7,100 cities on six continents announced this week
that they are creating a new alliance to fight climate change at the local level.
New York City
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

2015 Deadliest Year for
Environmentalists on Record, Finds Report
Last year was the deadliest year on record for environmentalists, according to a new report from Global Witness
, a nonprofit that tracks environmental and human rights abuses worldwide.
Indigenous people protest a dam in the Amazon.
One hundred and eighty-five people were killed trying to stop development of land, forests, and rivers in 16 countries in 2015 — equal to more than three people per week. The tally represents a 59 percent increase over 2014, and is double the number of journalists killed in the same period, according to the report. Environmentalists were most at risk in Brazil, the Philippines, and Columbia, which had 50, 33, and 26 killings last year, respectively. “This report sheds light on the acute vulnerability of indigenous people, whose weak land rights and geographic isolation make them particularly exposed to land grabbing for natural resource exploitation,” the Global Witness authors wrote. “In 2015, almost 40% of victims were indigenous.”

Some Coral Reef “Bright Spots”
Remain, Despite Devastating Bleaching
After decades of being overfished and mismanaged, and the worst bleaching event on record this year, scientists reported in the journal Nature this week
that there remain some “bright spots” among the world’s coral reefs

– systems that are doing better than anyone expected. The study examined 18 different factors at 2,514 reefs in 46 nations, including water depth, tourism, fishing, and population density. Those systems that were still thriving — defined by the scientists as having more fish than expected — tended to be managed by, and accessible only to, local fishermen and indigenous groups. This included reefs in places like the Solomon Islands, parts of Indonesia, Papua New Guinea, and Kiribati. “There’s been a narrative about local involvement, but it’s often very token,” Joshua Cinner, a research fellow at James Cook University in Australia and lead author of the study, told The Atlantic
. He said there should be more opportunity for “communities to creatively confront their own challenges.”

Clean Energy Could Cost Up To
59 Percent Less by 2025, Report Finds
The cost of solar energy could drop by as much as 59 percent by 2025, from 13 cents to 6 cents per kilowatt hour, according to a new report from the International Renewable Energy Agency
Rooftop solar panels in Hannover, Germany.
Offshore wind could become 35 percent cheaper, and onshore wind 26 percent cheaper, by 2025. The cost of building renewable energy facilities is also likely to fall, by as much as 57 percent by the middle of next decade, the report found. “Historically, cost has been cited as one of the primary barriers to switching from fossil-based energy sources to renewable energy sources, but the narrative has now changed,” Adnan Z. Amin, director-general of IRENA, said in a statement
. “To continue driving the energy transition, we must now shift policy focus to support areas that will result in even greater cost declines and thus maximize the tremendous economic opportunity at hand.”

Fish Can Recognize Human
Faces, According to One New Study
Fish now join humans, monkeys, primates, and birds as one of the few animals able to distinguish faces, according to new research published in the journal Scientific Reports
James St. John/Wikimedia
The skill requires a sophisticated combination of perception and memory
— and generally, a neocortex. But scientists at the University of Oxford in England and the University of Queensland in Australia were able to train archerfish to recognize human faces, despite the fact that these tropical fish don’t have complex brain structures. Archerfish typically feed by spitting water at prey, like insects. So the scientists taught the fish to spray water at images of particular human faces in exchange for food. Archerfish identified the correct person 81 percent of the time.

Fish Choose Plastic Over
Zooplankton in Polluted Waters
Fish that grow up in waters full of plastic particles develop a taste for trash, choosing to eat plastic over zooplankton, their natural food source, according to a study published in the journal Science
The research, by ecologists at Uppsala University in Swedish, found larval perch from the Baltic Sea exposed to microplastic pollution (less than 5mm in size) had stunted growth, were less active, ignored the smell of predators, and experienced increased mortality rates. Plastic pollution has become a major problem in the world’s oceans, but scientists are just beginning to understand how these fragments can affect the health of marine species. “If early life-history stages of other species are similarly affected by microplastics, and this translates to increased mortality rates, the effects on aquatic ecosystems could be profound,” said ecologist Oona Lönnstedt
, lead author of the study.

Climate Change Could Be Making
Food Crops More Toxic, UN Report Says
As extreme weather increases in frequency and intensity, food crops are producing more chemical compounds that can be toxic to humans in large doses, according to a recent report by the United Nations Environment Programme
Crops such as wheat, maize, and soybeans generate these compounds as a natural response to environmental stressors, such as drought, floods or heat waves. But when consumed by humans for extended periods of time, they can cause illnesses like neurological diseases or cancer, according to the study. One example, the Thomson Reuters Foundation reports
, is nitrate. Drought slows down plants’ conversion of nitrates into amino acids and proteins, leading to a build up of the compound. When consumed in large quantities, nitrates stop red blood cells from transporting oxygen in the human body. "We are just beginning to recognize the magnitude of toxin- related issues confronting farmers in developing countries of the tropics and sub-tropics," the UNEP report noted.

Bees’ Fuzzy Bodies Help Them
Detect Electrical Charges From Flowers
Back in 2013, scientists discovered that bees can detect the electrical charges that flowers emit, helping them locate nearby food sources.
Exactly how the bees were doing this, however, remained a mystery. Now, scientists have found that the hairs on bees’ fuzzy bodies move in response to the charges
, which send nerve signals to bees’ brains that flowers are nearby. The finding is an important one: Scientists have long thought
that only animals in marine or moist habitats could detect electric fields, since currents are carried through water. That bees can do this in dry air opens up the possibility that other insects might have the same ability. The research, conducted by scientists at the University of Bristol in the U.K., was published this week in the journal Proceedings of the National Academy of Sciences

Could This Straddling Bus Help
Solve China’s Air Pollution Problem?
With an estimated 20 million new drivers on the road each year, China has long struggled to control its CO2 emissions, air pollution, and traffic problems.
But a Beijing-based transit company is planning to test a new straddling bus this summer
that could provide some relief, according to Chinese news agency Xinhua. The bus, which can carry up to 1,400 passengers, hovers above the road, letting smaller vehicles pass underneath. Because it operates on existing roadways, the system is much cheaper to build than underground subways, while carrying the same number of people. The idea of a straddling bus has been around since 1969
, but has remained a far-fetched concept until recent years. A model of the system, designed by Transit Explore Bus, was unveiled at the International High-Tech Expo in Beijing this month. The company plans to build and test an actual straddling bus in Changzhou this summer.

World Could Warm 8 Degrees
Celsius If All Fossil Fuel Reserves Burned
As nations meet in Bonn, Germany this week to hash out how to achieve the 2-degree Celsius goal they set in Paris, new research is providing policymakers a glimpse of what would happen if the world does nothing to curb climate change.
What if nations chose instead to burn through all of their remaining fossil fuel reserves, equal to 5 trillion tons of CO2 emissions? According to the new study published in the journal Nature Climate Change
, the world would warm an average 8 degrees Celsius (14.4 degrees F), or up to 17 degrees Celsius (30 degrees F) in the Arctic. The research was conducted by a team of climate scientists at the University of Victoria and Simon Fraser University in British Columbia who wanted to understand the worst-case scenario. “Such climate changes, if realized, would have extremely profound impacts on ecosystems, human health, agriculture, economies, and other sectors,” the researchers write.
Interview: CO2 'Air Capture' Could
Be Key to Slowing Global Warming
For two decades, Klaus Lackner has pioneered efforts to combat climate change by pulling carbon dioxide from the atmosphere.
Now, after years of watching the global community fail to bring greenhouse gas emissions under control, Lackner — director of the Center for Negative Carbon Emissions at Arizona State University — is delivering a blunt message: The best hope to avoid major disruptions from global warming is to launch a massive program of CO2 "air capture" that will begin to reverse the buildup of billions of tons of carbon in our atmosphere. "We need to have the ability to walk this backwards," says Lackner. "I'm saying this is a war, and we need to use all the weapons at our disposal. You don't want to get into this fight with one hand tied behind your back."

Fumes from Farms Are
Top Source of Fine-Particle Pollution
Farms are the number one source of fine-particulate air pollution in the U.S., Europe, Russia, and China, according to new research published in the journal Geophysical Research Letters
Gases from fertilizers and livestock waste cling to emissions from cars, power plants, and factories to create solid particles less than 1/30th the width of human hair. Particles this size have been shown to penetrate deep into lungs, and cause an estimated 3.3 million deaths each year from illnesses like heart and pulmonary disease. Global climate action, however, could reduce this type of air pollution in the coming decades, says the new study, done by three Columbia University scientists. Cutbacks in energy consumption would mean that fumes from farms would have fewer emissions to which they could bond. This reduction in particulates would happen even if fertilizer use increases, the research says.

Despite Push for Renewables,
Fossil Fuels Likely to Dominate in 2040
World leaders pledged last year in Paris to cut CO2 emissions and limit global warming to 2 degrees Celsius. Despite these promises, U.S. analysts said Wednesday
that fossil fuels
— including coal — will still likely be the world’s primary source of energy in 2040. The findings are part of the U.S. Energy Information Administration’s annual World Energy Outlook report. Electricity from wind, solar, and hydropower will grow 2.9 percent annually, the report concluded, and by 2040, renewables, coal, and natural gas will each generate one-third of the world’s electricity. But diesel and gasoline will still power the majority of vehicles, with electric cars making up only 1 percent of the market, the report said. The report also found that carbon emissions from energy consumption in the developing world could grow 51 percent from 2012 to 2040
as countries like India and China modernize their economies, particularly by using coal.
