Scientists Study the Skies
To Create a Map of the World’s Biomes
Curious where certain species live? Don’t look down. Rather, study the skies, according to new research published in the journal PLoS Biology
. Scientists from the University of Buffalo and Yale University
used images from NASA satellites to build a database of cloud cover for every square kilometer of the planet from 2000 to 2014. They then used the information to map the world’s biomes. They found that cloud patterns are a much more accurate way of predicting species distribution than using extrapolated on-the-ground observations, the method most conservationists use today. “Sunlight drives almost every aspect of ecology,” Adam Wilson, an ecologist at the University of Buffalo who led the study, told New Scientist
. “So when you put something in between the sun and plants, that is going to have implications on the amount of energy they are receiving, soil moisture, leaf wetness, and humidity—almost everything that is important.”

A New, Multi-Colored Way To
Study Cell Regeneration in Zebrafish
Zebrafish have amazing healing capabilities—they can grow back missing limbs and patch an injured heart or spine—but scientists have long been in the dark as to how exactly this process works.

Now, a team of scientists at Duke University engineered neurons to create a zebrafish with skin that fluoresces in thousands of colors
in order to visually illustrate how cells regenerate after injury. They found there are three steps to the process: skin cells from neighboring body parts migrate in to cover the new tissue, surviving cells grow in size, and new cells are created. “It is like you have given each cell an individual barcode,” said
Chen-Hui Chen, a postdoctoral fellow at Duke and lead author on the study. “You can precisely see how individual cells collectively behave during regeneration.”
Interview: How Ocean Noise
Wreaks Havoc on Marine Life
Bowing to public pressure, the Obama administration recently reversed an earlier decision to allow oil drilling off the U.S. East Coast. But the five-year moratorium on drilling does not prohibit exploratory seismic air gun surveys
used to locate oil and gas reserves under the seabed, and those surveys are expected to be authorized this spring. Cornell University marine bioacoustics expert Christopher Clark says the testing, which can go on for weeks at a time, will only add to the rising din in the oceans. “Imagine that every 10 seconds there is an explosion that is rattling grandma’s china out of the cupboard,” he says, “and it is falling on the floor.” In an interview with Yale Environment 360
, Clark explains how noise, most of it from ship traffic, severely disrupts marine life, especially among whales. But the good news, he says, is that technologies are being developed to drastically reduce the noise from ships and geological surveying.

Air Pollution Linked To
Thousands of U.S. Premature Births
Air pollution may be causing thousands of premature births in the U.S. every year, particularly in urban areas like the Ohio River Valley, Southern California, New York City, and Chicago, according to a new study
in the journal Environment Health Perspectives
. Scientists at New York University compared levels of fine particulate matter, a type of pollution less than 2.5 micrometers in diameter, to numbers of premature births, meaning a baby born more than three weeks early. They found that over three percent of all preterm births in the U.S. in 2010 can be attributed to air pollution, and that it cost the country more than $4 billion in medical expenses and lost economic productivity. The exact mechanism behind this relationship is not known, but researchers theorize that air pollution inflames the placenta
during pregnancy, spurring early labor. Preterm birth is associated with a slew of medical issues, from cognitive impairment to breathing and feeding problems.

As U.S. Oil Production Increases,
More Americans At Risk of Man-Made Quakes
As U.S.-based production of oil and gas has boomed over the last decade, millions of gallons of chemical-laden wastewater has been pumped and stored deep underground.
The risk of experiencing an earthquake in 2016.
It turns out, however, that this disposal method—popular for fracking waste—is causing a spike in the number of earthquakes across the country, according to a new set of maps from the U.S. Geological Survey
. Seven million Americans are now at risk from man-made quakes, particularly in Oklahoma, Kansas, Texas, Colorado, New Mexico and Arkansas. "My first thought was actually, ‘Holy crap, Oklahoma is redder than California,’" USGS geologist Susan Hough told The Washington Post
about seeing the maps for the first time. Unlike California, however, most of these states don’t have earthquake-ready structures, experts said, so communities are having to update building codes and purchase new insurance.

Majority of Meteorologists Now
Agree Climate Change is Happening, Manmade
Meteorologists have long lagged behind scientists and even the general public in acceptance of modern anthropogenic climate change.

Four years ago, only 19 percent of TV weather forecasters said they believed human actions were the primary driver of global warming. Today, however, 67 percent of TV and non-TV meteorologists agree that climate change is manmade, according to a new survey by George Mason University
. An additional 14 percent said human activity and natural factors are equally responsible. Overall, 96 percent said climate change is happening, no matter the reason. The shift comes after a string of shattered monthly temperature records and wild weather, and growing international attention to the issue following the UN Paris climate conference in December. Ed Maibach, lead author of the survey and director of George Mason’s Center for Climate Change Communication, said the upswing didn't surprise him
. “That is how science works. As the scientific evidence becomes more irrefutable, which is the case with harmful, human-caused climate change, more scientists of all types will become convinced,” he said.

A Fish With a Pelvis: Another
Clue Into Our Sea-to-Land Evolution
Biologists have long wondered exactly how fish emerged from the sea and transitioned into vertebrates that could walk on land. To date, most of the information on that shift has come from fossils,
A waterfall-climbing fish.
but scientists reported Thursday they have found that a species of fish located only deep in the caves of Thailand walks the same way land vertebrates do
. The blind waterfall-climbing fish, Cryptotora thamicola
, first discovered in 1985, has skeletal features similar to a salamander—including a fully formed pelvis—that enable them to climb up rock walls and feed on microbes and organic matter as water comes crashing down on them, the researchers wrote in Nature Scientific Reports
. “Functionally, it makes perfect sense, but to see it in a fish is incredibly wild,” said
Brooke Flammang, an expert on biomechanics at the New Jersey Institute of Technology and lead author of the study. The discovery could help more fully explain how life evolved from the sea to land.

Microbes Are Likely Speeding
Up the Melting of the Glaciers
As if soaring global temperatures weren’t bad enough, scientists reported this week that microbes are also speeding up the melting of Arctic ice.

The problem lies in cryoconite, the soil-like composite of dust, industrial soot and photosynthetic bacteria that darkens the surface of ice and causes it to melt, scientists from Aberystwyth University in Wales said. As it melts, ice leaves behind small water-filled holes full of bacteria. The sun-loving microbes then shape the pockmarks’ depth and size to get more light exposure, in turn melting the ice even more—a process previously unaccounted for in global climate change models. "It's only recently that we've begun to understand that these cryoconite holes are dynamic, changing in size and shape,” said
biologist Arwyn Edwards, who led the study. "In the long term, this contributes to the loss of glacier habitats, and the unique microbial biodiversity living on them."

Old Photos Used to Study
The Fate of a Swedish Seabird Colony
Nearly 100 years of old tourist photos got a second life recently when researchers used them to reconstruct the rise and fall
of a colony of seabirds on the Swedish island of Stora Karlsö. The island, designated a nature preserve in 1880 and a popular tourist destination since the 1920s, hosts a large population of common guillemots, one of the biggest species of auks. Ecologists Jonas Hentati-Sundberg and Olof Olsson of Stockholm University spent five years collecting images of the island from archives, museums, and island visitors in order to count guillemot numbers decade-to-decade. They found that the colony declined in the 1960s and 70s, when contaminants like DDT and PCB were prevalent, but has since rebounded to historically high numbers today, possibly because of an increase in the numbers of forage fish consumed by guillemots. “The population is currently increasing at an unprecedented rate
of about 5 percent annually," said Hentati-Sundberg. "This is interesting in that many common guillemot populations are decreasing worldwide."

Newly Discovered Butterfly
Could Be Climate Bellwether in the Arctic
Scientists have discovered the first new butterfly species in Alaska in nearly 28 years, according to new research
published in the Journal of Research on the Lepidoptera
The dorsal side of new species Oeneis tanana.
Named the Tanana Arctic, or Oeneis tanana
, the species is thought to be a hybrid and the only butterfly endemic to the state. Because butterflies are so sensitive to environmental change, the Tanana Arctic could serve as an early warning signal to the impacts of climate change in the region, the scientists said. “This butterfly has apparently lived in the Tanana River valley for so long that if it ever moves out, we’ll be able to say ‘Wow, there are some changes happening,’” said
Andrew Warren, the senior collections manager at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of Natural History who discovered the species. “This is a region where the permafrost is already melting and the climate is changing.”

Could Bread Mold Help
Improve Rechargeable Batteries?
A type of bread mold might just be a key to creating better rechargeable batteries, scientists reported in the journal Current Biology
Researchers at the University of Dundee in Scotland discovered that the fungus Neurospora crassa
—known commonly as red bread mold—can transform manganese into a mineral composite with “excellent electrochemical properties” ideal for use in supercapacitors or lithium-ion batteries, said
Geoffrey Gadd, a microbiologist and lead author of the study. Those types of batteries are used to power everything from laptops to railways to solar energy systems. Scientists have long studied how to make batteries more powerful and sustainable and in an environmentally safer way, but this is the first time researchers have looked to mold as a possible solution.

The World’s Economy Grew,
But Greenhouse Gas Emissions Didn't
Despite a 3.1 percent growth in global GDP in 2015, greenhouse gas emissions remained flat for the second year in a row, according to the International Energy Agency.
A man installs new solar panels in Oregon.
The decoupling of emissions from economic growth is “welcome news,” IEA executive director Fatih Birol said in the press statement. “Coming just a few months after the landmark COP21 agreement in Paris, this is yet another boost to the global fight against climate change.” The world’s nations released 32.1 billion metric tons of greenhouse gases last year, equal to—or perhaps even a slight downtick from—2014, the agency said. The stabilization is likely due to the booming renewable energy industry and global cutbacks on the use of coal, particularly in the U.S. and China, the two largest emitters of carbon dioxide. Chinese emissions, for example, declined 1.5 percent last year.

Storks Stop Migrating South
In Favor of Food Waste From Landfills
White storks are no longer migrating to Africa every winter, choosing instead to stay near landfills and other garage heaps in southern Europe that provide scavenged food year round, according to new research published Wednesday in the journal Movement Ecology
University of East Anglia
Storks feeding in a landfill.
Sticking close to uncovered trash piles in Europe means the birds no longer have to expend energy flying all the way south to Africa, and can arrive at the best northern nesting sites and breed earlier in the year. As a result, storks have been having bigger broods and higher fledging survival rates. “Portugal’s stork population has grown 10-fold over the last 20 years,” Aldina Franco, a conservation ecologist at the University of East Anglia in Britain who led the study, said
in a statement. “The country is now home to around 14,000 wintering birds, and numbers continue to grow.” Franco and her colleagues’ findings build on the growing scientific understanding
of how our waste is altering the world’s wildlife.
Interview: How to Talk About
Young Conservatives for Energy Reform
Clean Energy With Conservatives
promotes a green energy agenda for Republicans. But the phrase “climate change” isn’t one you’ll find on the organization’s website.
Angel Garcia, the group’s national outreach coordinator, admits that pushing renewables in conservative circles is an uphill battle. “We have an ideology that seems like it’s ‘Drill, baby drill,’ with nothing else. So we have to fight against stereotypes that if you’re for clean energy, then you are not really a Republican.” In an interview with Yale Environment 360
, Garcia says the Republican Party has a vested interest in embracing clean energy since the issue resonates with young conservatives. “As demographics shift, this is becoming a more important issue. So it’s better to get in front of the issue now and embrace it.”

Obama Administration Pulls
Proposal to Drill in the Atlantic Ocean
The Obama administration withdrew its proposal to open up offshore oil and gas drilling in the Atlantic Ocean on Tuesday.

The decision blocks drilling in the region until 2022 and comes after an outpouring of opposition
to the plan from environmental groups and mid-Atlantic coastal communities and businesses concerned about a possible spill like Deepwater Horizon in the Gulf of Mexico five years ago. “Public pressure forced the administration to reverse course on Atlantic drilling," May Boeve, executive director of the environmental group 350.org, said in a statement. “We will continue to make the case that any new drilling is a stain on the president’s climate legacy and incompatible with the goals he committed to at the climate talks in Paris.”

Sea Level Rise Could Put
13.1 Million Americans At Risk of Flooding
Climate change and sea level rise could put 13.1 million Americans at risk of flooding by 2100, according to a new study
in the journal Nature Climate Change
Flooding in Davie, Florida
Nearly half of the at-risk population resides in Florida, and 70 percent in the southeastern United States. Unlike previous assessments that looked only at sea level rise, the study examines both climate and population projections for all 319 coastal U.S. counties over the next century. Three feet of sea level rise puts 4.2 million Americans at risk. Six feet—the high end of estimates by the National Oceanic and Atmospheric Administration—puts 13.1 million at risk. “The impact projections are up to three times larger than current estimates, which significantly underestimate the effect of sea level rise in the United States,” said
Mathew Hauer, lead author of the study and a demographer at the University of Georgia.

Five Years After Nuclear Disaster
Fukushima Remains Highly Contaminated
It has been five years since a powerful earthquake and resulting tsunami caused a meltdown at the Fukushima Dai-ichi Nuclear Power Plant in Japan.
Regulators visit the Fukushima site in 2014.
While a few towns closed after the disaster have reopened and some locals have returned, groundwater en route to the ocean, as well as nearby soils, remains highly contaminated with radioactive waste. Toxic water and soil that has been removed by the cleanup project’s 8,000 workers sits in a growing number of storage tanks on the property, several of which have leaked. Radiation levels are so high that robots sent to clean up the power plant itself are reportedly malfunctioning
, their circuits fried. "Fukushima Dai-ichi is a complicated cleanup site," said
Dale Klein, a former chairman of the U.S. Nuclear Regulatory Commission who now consults for the Tokyo Electric Power Company, which owns the plant. "This will be a several-decades process of cleanup.”

China Aims to Pass Soil Pollution
Law, Addressing Widespread Contamination
China is aiming to pass its first soil pollution law next year to address what Chinese officials are calling a “serious” problem of widespread contamination of the nation’s agricultural land.

The pollution is the result of three decades of rapid economic and industrial development that left landscapes ridden with toxins and heavy metals
, contaminated staple crops like rice, and jeopardized public health. “Looking at the results of soil pollution surveys from relevant departments of the State Council … it's not easy to be optimistic. Some areas are seriously polluted," Yuan Si, deputy head of parliament's Environmental Protection and Resources Conservation Committee, told
reporters. The soil pollution law has gone through 10 drafts already and will likely be put on the legislative agenda for 2017, Yuan said.
In Flint Crisis, A New Model
For Environmental Journalism
Last summer, investigative journalist Curt Guyette found himself knocking on doors of families in Flint, Michigan, carrying not only a pen and notebook, but water-testing kits. Residents had realized there was something wrong with their drinking water but Michigan officials insisted it was safe.
Guyette, the first investigative reporter in the nation hired by an American Civil Liberties Union (ACLU) chapter, broke the story on possible widespread lead contamination in July. He then helped organize door-to-door testing for lead and filed Freedom of Information Act requests in search of the truth. In an interview with Yale Environment 360
, Guyette explains how he chased the story, his unique position as a Ford Foundation-funded journalist employed by ACLU Michigan, and whether this approach to journalism could be a model for rescuing in-depth, local reporting on complex environmental and public health issues.

U.S., Canada to Announce Series
Of New Climate and Environment Initiatives
President Obama and Canadian Prime Minister Justin Trudeau are expected to announce a series of environment and climate initiatives during Trudeau’s first visit to the White House later this week.
The measures include a 45-percent cut in methane emissions from the oil and gas industry and a partnership to protect the rapidly melting Arctic from climate change. Trudeau’s focus on global warming since winning office four months ago marks a significant shift in Canada’s environmental policy. Its previous prime minister, Stephen Harper, cut funding for climate research
and backtracked on international climate pledges. “The commitment of both leaders to addressing this global challenge is clear,” Todd Stern, the U.S. Special Envoy for Climate Change, said
. “I suspect under their leadership, North America will make significant progress this year and next.”

JP Morgan Will No Longer Invest
In New Coal Mines, Citing Climate Change
JP Morgan will no longer finance new coal mines or support new coal-fired power plants in “high income” countries, the banking giant said
in a policy statement on its website.
Coal mine in Jharia, India
Bank of America, Citigroup, Morgan Stanley and Wells Fargo have made similar pledges in recent months, all part of a larger divestment movement aimed at transitioning the world’s economies off fossil fuels. The anti-coal campaign has dealt a blow to an already struggling industry. The price of coal has dropped from $140 per ton in 2009 to $42 in 2016 as cheap, abundant natural gas and renewables have flooded the U.S. energy market. At the same time, support for climate action has grown, with the signing of an international climate agreement in Paris last December. “We believe the financial services sector has an important role to play as governments implement policies to combat climate change,” JPMorgan said
in the document.

Climate Change Will Threaten Key Crops Across Sub-Saharan Africa
Climate change’s rising temperatures and more frequent and intense droughts could leave parts of sub-Saharan Africa unable to grow staple crops such as maize, bananas, and beans by the end of the century,

according to new research
published Monday in the journal Nature Climate Change. Up to 60 percent of bean-producing areas and 30 percent of maize and banana farms could become unviable by 2100, and farmers should start growing more climate change-resistant crops, improve irrigation systems, or switch to raising livestock, the scientists said. “Agriculture and farming are critical not only for the livelihoods of farmers but also more broadly for the diets of the region’s population,” said
Julián Ramírez-Villegas, a scientist at the International Center for Tropical Agriculture and lead author of the study. “Unless timely adaptation actions are taken, we’re looking at a bleak picture in terms of food security and poverty throughout many areas of sub-Saharan Africa.”

Oil Purchases Linked to Rainforests
, some of the world’s largest consumer companies admitted that
Rainforest in Borneo cleared for palm oil
they have no idea whether the palm oil they purchase from Indonesia is linked to rainforest destruction, according to a new report from Greenpeace
, which surveyed 14 companies, including PepsiCo, Mars, Unilever, and Johnson & Johnson. “Palm oil is found in so many products, which is why brands have a responsibility to their customers to act,” said Greenpeace’s Annissa Rahmawati
. “But our survey shows that brands are not doing enough to stop the palm oil industry ransacking Indonesia’s rainforests.” Indonesia is the world’s largest producer of palm oil, a vegetable oil used in a wide range of household products, from lipstick to soap to instant noodles, and environmentalists have long argued the industry is a leading cause of deforestation. Since 1990, Indonesia has lost 76 million acres of forest, an area almost equal to the size of Germany.

Oregon To Eliminate Coal
From Its State Energy Mix by 2030
Oregon has become the first U.S. state to eliminate the use of coal by legislative action. Lawmakers at the statehouse
Oregon's only remaining coal plant, in Boardman
voted Wednesday to eliminate coal from the state’s energy supply by 2030, and to provide half of all customers’ power with renewable sources by 2040. The legislation was hammered out between the state’s two largest utilities and environmental groups. Clean energy groups praised the legislation as one of the strongest pieces of pro-climate legislation in the U.S. in years. “In terms of the coal phase-out, this really is precedent setting,” said Jeff Deyette
, senior energy analyst at the Union of Concerned Scientists. There is only one coal plant currency operating in Oregon, and it is the state's largest single source of greenhouse gas emissions.
Rethinking Urban Landscapes To Adapt to Rising Sea Levels
Sea levels are rising faster than they have in at least 28 centuries, according to recent research, and by 2100, they are expected to rise by one to four feet — possibly even higher.
Landscape architect Kristina Hill argues that cities throughout the world need to start planning now for impacts that will happen 50 or 100 years in the future. “It takes decades for us to get our act together and build things,” says Hill, an associate professor at the University of California, Berkeley. “Future generations won’t have the luxury of decades.” Hill advocates blending natural ecosystems and human-made infrastructure to help cities adjust to rising tides. In an interview with Yale Environment 360

Despite El Nino, California Has Dry February As Drought Continues
El Nino failed to deliver much needed rain to California in February, dashing hopes that the climatic phenomenon could help end the state’s crippling four-year, multi-billion-dollar drought.
Ninety-four percent of California is in drought.
Downtown Los Angeles received only .79 inches of rain last month, when it typically gets 3.8 inches. The Bay Area got similarly low totals. "From past six strong El Ninos, we have generally seen above normal rainfall,” said
Robbie Munroe, a meteorologist for the National Weather Service. “But since October 1 we've only seen five inches of rain so far (across Southern California). We were certainly expecting a lot more." Meteorologists say a series of forecasted storms in early March could help, but with El Nino reportedly weakening and about 94 percent of California still in some form of drought, things aren’t looking good for the region.

China's CO2 Emissions Fell in 2015 Due to Decline in Coal, Boost in Renewables
China's greenhouse gas emissions fell for the second year in a row in 2015, down 1 to 2 percent, according to a Greenpeace analysis
of new data released by China's National Bureau Statistics.
The Tangshanpeng Wind Farm in northern China.
China reduced its coal consumption 3.7 percent
in 2015, and installed 32.5 gigawatts (GW) of wind and 18.3 GW of solar power. The country's recent economic slowdown also helped reduce emissions. China is currently the world's largest emitter of CO2, responsible for nearly a quarter of global greenhouse gas emissions. At a UN climate conference in Paris in December, China pledged to peak its emissions by 2030 and boost renewables. "These statistics show that China is on track to far surpass its Paris climate targets," said Lauri Myllyvirta, a senior campaigner on coal for Greenpeace. "However, the trend is not moving as fast as it could."

California Natural Gas Leak Officially Largest Leak in U.S. History
The four-month natural gas leak that sickened hundreds of Los Angeles residents and forced the evacuations of 1,800 homes this winter has officially been deemed the largest methane leak in U.S. history, according to a study
in the journal Science
A natural gas facility in California's Aliso Canyon.
The California leak spewed a total 97,100 metric tons of methane into the atmosphere, up to 60 tons per hour—the equivalent of the annual greenhouse gas emissions of 572,000 cars. Methane is a greenhouse gas dramatically more potent than carbon dioxide over a short time span. The researchers collected the data during 13 different flights through the leaking gas plume. The measurements were so high the scientists said they double-checked their recording devices. "It became obvious that there wasn't anything wrong with the instruments," said
Stephen Conley, an atmospheric scientists at the University of California-Davis who led the study. "This was just a huge event."

Scientists find new large lizard species on remote Papua New Guinea island
Scientists have discovered the first new large lizard species in Papua New Guinea in over 20 years. The lizard was found on Mussau Island, one of the northernmost islands in country, by a team of Finnish and Australian researchers.
The new Varanus semotus.
The scientists have dubbed the new species, Varanus semotus
, a “biogeographical oddity” because it is separated by several hundred miles from its next of kin. Islands in the Pacific Ocean lack predatory mammals, so large lizards, commonly known as monitor lizards, the most famous of which is the Komodo dragon, fill that role. The new lizard measures 3 feet 3 inches, has a black body covered with yellow and orange markings, and a pale yellow tongue. "Isolation is the keyword here," said
Valter Weijola, a graduate student from the University of Turku in Finland who led the trip. "It is what has driven speciation and made the South-Pacific region one of the world's biodiversity hotspots."

Extended Bleaching Events
Are Killing Corals As Oceans Warm
Rising ocean temperatures are intensifying the die-off of corals around the planet, according to U.S. government scientists. “We are currently experiencing
Bleached coral at the Great Barrier Reef
the longest global coral-bleaching event ever observed,” said Mark Eakin
, head of Coral Reef Watch at the National Oceanic and Atmospheric Administration. Bleaching occurs when corals respond to environmental hazards, such as high ocean temperatures, by expelling the symbiotic algae they need to provide them with sustenance. Eakin predicted that the latest extended bleaching event, which started in 2014, will likely last well into next year, at which time about 60 percent of corals worldwide may be affected. Eakin compares the continuous pressure that reefs have been under in recent years to a boxing bout. “What used to be a one-round fight is turning into a two- and three-round fight,” he says.
