05 May 2016: With Climate Change, It Is
Survival of the Oldest, Not the Fittest

When it comes to climate change, the world’s oldest species are more likely to survive than newly evolved ones, says a new study published in the journal BMC Evolutionary Biology.

The logic is relatively simple: The reason they’re so old is that they’ve been tested by abrupt environmental shifts before and have come out on top. This group includes species like the cane toad and California sea lion. More specifically, the study found the planet’s oldest animals all share at least one of the following characteristics: They come in various colors, give birth to live young (as opposed to eggs), and live at low latitudes. The research could help “predict which [species] could be better able to deal with current climate change and to better predict the threat status of species on the red list of the International Union for Conservation of Nature,” said Sylvain Dubey, an ecologist at the University of Lausanne in Switzerland and co-author of the new study.

28 Apr 2016: Half of All Farmed Fish Have
Deformed Ear Bones That Cause Hearing Loss

Farmed fish have become an increasingly larger share of the world’s seafood market in recent decades—now accounting for 50 percent of global seafood consumption.

USFWS
At the same time, however, debate about the ethics, safety and health of farmed fish versus their wild counterparts has also intensified. A new study published in the journal Nature Scientific Reports finds that half of all farmed Atlantic salmon have deformed ear bones that lead to hearing loss. These salmon are 10 times more likely to have the deformity than wild fish. The findings “raise questions about the welfare of farmed animals," said Tim Dempster, a biologist at the University of Melbourne involved in the study. It may also explain why efforts to boost wild populations by releasing farmed juveniles have proven unsuccessful. Hearing loss would prevent farmed fish from detecting predators, or restrict their ability to navigate to breeding sites, the scientists said.

27 Apr 2016: Wooden Skypscrapers Grow in
Popularity in Effort to Reduce Emissions

Architects are increasingly abandoning traditional steel-and-cement skyscrapers in favor of wood-and-glue designs — a move that experts say could help drastically reduce CO2 emissions from the world’s building sector.

Acton Ostry Architects
Creating steel, iron, and non-metallic minerals — including concrete — is an energy-intensive process that accounts for more than 10 percent of global greenhouse gas emissions. In the 1990s, developers created a product known as cross-laminated timber — planks of wood glued together by a polyurethane adhesive — with the strength and durability of traditional building materials, and far fewer CO2 emissions. With concern for climate change mounting, wood-based skyscrapers have been popping up around the globe in recent years. The University of British Columbia, for example, approved an 18-story, wooden housing complex in 2015. “This revolution has happened rather quietly and happened rather slow,” Kris Spickler, a heavy timber specialist at Structurlam, told Popular Science. “But I think we’re in a year right now where we’re going to see it explode.”

26 Apr 2016: Historical Citizen-Scientists’ Ice
Records Confirm Global Temperature Rise

Centuries-old records from Japanese priests and European shipping merchants are helping scientists confirm that the earth has warmed substantially — and freshwater ice formation significantly decreased — since the Industrial Revolution.

These early record keepers tracked annual freeze dates and the breakup of ice each spring on lakes and rivers for hundreds of years, beginning in the 1440s in Japan and 1690s in Finland. The data represents the oldest known inland ice records. An international team of scientists published a study this week in Nature Scientific Reports examining how ice behavior changed over the records’ years. They found that from 1443 to 1683, for example, the annual freeze date of Lake Suwa in Japan moved back 0.19 days per decade. From the start of the Industrial Revolution, however, that trend grew 24 times faster, pushing back the date of ice formation on the lake by 4.6 days per decade.

19 Apr 2016: Thirty Years After Chernobyl,
Wildlife Thrives in the Contaminated Zone

Thirty years after the meltdown of the Chernobyl Nuclear Power Plant in Ukraine, humans remain relatively scarce near the accident site.

Wildlife, however, is thriving, according to a recent study by scientists at the University of Georgia. The researchers set up cameras at 94 sites in the Chernobyl Exclusion Zone—a 1,000-square-mile area where radiation levels remain high—and applied a fatty acid scent to attract animals. In total, they saw 14 mammal species in the footage, most frequently gray wolves, boars, red fox, and raccoon dogs. Since carnivores tend to accumulate radiation faster that animals further down the food chain, finding so many of them was good news. "We didn't find any evidence to support the idea that populations are suppressed in highly contaminated areas,” said James Beasley, an ecologist at the University of Georgia who helped lead the study.

18 Apr 2016: The Complicated Case of
Global Warming’s Impact on Agriculture

Scientists have long debated whether climate change could help or hurt the world’s agricultural systems. Theoretically, additional CO2 in the atmosphere should help fuel crop growth.

But global warming’s other impacts, such as shifting rain patterns, higher temperatures, and extreme weather, could reduce crop yields. A new study in the journal Nature Climate Change by researchers in a half-dozen countries finds the answer depends on where you live. The scientists found yields of rain-fed wheat could increase by 10 percent, while irrigated wheat, the bulk of India and China’s production, could decline by 4 percent. Maize will decrease almost everywhere, down 8.5 percent. Rice and soybean could flourish in some areas and falter in others. “Most of the discussion around climate impacts focuses only on changes in temperature and precipitation,” said Delphine Deryng, an environmental scientist at Columbia University who led the study. “To adapt adequately, we need to understand all the factors involved.”

12 Apr 2016: Scientists Reimagine The
Tree of Life With New Microbe Knowledge

Following years of intense exploration and research into the microbial world, scientists have reimagined the tree of life—the iconic visual representation of the living world first proposed by Charles Darwin in 1859.

The project was led by researchers at the University of California, Berkeley, who over the last decade have been gathering DNA from across the globe—from everywhere from meadow soils and river mud to deep sea vents—to reconstruct genomes and describe thousands of new microbial species. Curious how their findings fit into the tree of life, the scientists used a supercomputer to visualize how more than 3,000 new and known species related to one another. They discovered that eukaryotes, the group that includes humans, exist on a thin twig compared to the microbial branch of the tree. “The tree of life as we know it has dramatically expanded due to new genomic sampling of previously enigmatic or unknown microbial lineages,” the authors wrote.

For James Hansen, the Science

and he has led study after study examining how our world will change as a result of global warming. Eight years ago, Hansen made the rare decision to begin engaging in climate activism—a move that has earned him both praise and criticism from the media and scientific community. In an interview with Yale Environment 360 last week, Hansen opened up about his unconventional career path and what he believes the world could look like a century from now. “I don't think that I have been alarmist — maybe alarming, but I don't think I'm an alarmist,” he said. “We have a society in which most people have become unable to understand or appreciate science, and partly that's a communication problem, which we need to try to alleviate.”

07 Apr 2016: How Ancient Algae Could
Help Cure Brain and Breast Cancer

One of the oldest life forms on earth may hold the key to battling hard-to-treat cancers, according to new research by scientists at Oregon State University. The compound, coibamide A, is found in blue-green algae, organisms that have existed for at least two billion years. It was found during a diving trip in Panama’s Coiba National Park eight years ago and run through the National Cancer Institute’s database of potential anti-cancer compounds. Coibamide A was tested on mice and found to be more effective at killing brain and triple negative breast cancer cells—two of the most aggressive and hard-to-treat types of the disease—than anything ever tested before. "The chemical diversity found in nature has always been a significant source of inspiration for drug design and development, but… marine environments remain relatively unexplored," said Jane Ishmael, a cellular biologist at Oregon State University and lead author of the new study.

range from Mount Kilimanjaro in Tanzania to the Great Barrier Reef in Australia, China’s panda sanctuaries, and the Grand Canyon in the United States. A new survey by the World Wildlife Fund, however, has found half of these sites are under threat from oil and gas development, mining, illegal logging, overfishing, or other industrial activities. Eleven million people live in or near these sites, the report says, and depend on them for their housing, food, water, jobs, or ecosystem services like flood protection and CO2 sequestration. “We are not going to develop a just and prosperous future, nor defeat poverty and improve health, in a weakened or destroyed natural environment,” the authors wrote.

01 Apr 2016: Scientists Study the Skies
To Create a Map of the World’s Biomes

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.”

22 Mar 2016: 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."

17 Mar 2016: 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.

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.

16 Mar 2016: 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.

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.

08 Mar 2016: JP Morgan Will No Longer Invest

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.

29 Jan 2016: European Summers Hottest Since
Roman Empire, Tree Ring Analysis Finds

For the past three decades, Europe has been experiencing its warmest summers since the days of the Roman Empire, according to a study published in the Environmental Research Letters Journal. The study, compiled by 40 academics, concluded that average summer temperatures have been 1.3 degrees Celsius hotter than they were 2,000 years ago. Heat waves also occur more often and last longer. The temperature figures were calculated by analyzing the tree ring analysis of three pine species found in Austria, Sweden, and Finland, as well as climate modeling and historical documents. The report says that summers were particularly warm between Roman times and the third century, before cooling until the 7th century. Temperatures warmed up again during medieval times, then dropped again from the 14th to 19th centuries. The recent warming, however, is unprecedented and cannot be explained by natural variability, but is directly related to manmade climate changes, the scientists said.

06 Nov 2015: Austria’s Largest State Now
Generates All Electricity from Renewables

The electricity supply in Lower Austria, the largest state in Austria, is now fossil-free, state officials have announced. The state in northeastern Austria, which has a population of 1.65 million, now gets 63 percent of its electricity from hydroelectric power, 26 percent from wind energy, nine percent from biomass, and two percent from solar. While hydroelectric power has always generated a large portion of the state’s electricity, Premier Erwin Proell said that $3 billion in investments since 2002 in utility-scale solar and other renewables had helped the state reach the 100 percent renewables target. Proell said the expansion of renewables has created 38,000 green jobs in the state, with the aim of generating 50,000 jobs in the renewables sector by 2030. Throughout Austria, 75 percent of electricity generation now comes from renewable energy sources.

02 Oct 2015: Brown Carbon Plays Larger Role
In Climate Than Assumed, Study Says

Climate models are underestimating the effects of so-called brown carbon from sources such as forest fires because the models

do not account for regional factors — such as areas where wood-burning stoves are common — when estimating brown carbon's climate-warming impacts. Black carbon, primarily from urban combustion sources like vehicles and factories, absorbs the most sunlight, the researchers explain, and it's well-accounted for in climate models. However, most models don't properly account for brown carbon, the researchers say. Brown carbon "can be a significant absorber of sunlight, making it as bad for climate warming as black carbon," said co-author Manvendra Dubey of Los Alamos National Laboratory. The study, published this week in Nature Communications, stresses the differing effects of black and brown carbon on the climate: Solid wood combustion, a source of brown carbon soot, is pervasive during United Kingdom winters, but very uncommon in other study locations, such as Los Angeles, which generally sees more black carbon soot from vehicles.

Once enough data has been collected, the researchers plan to create maps showing where ground-level air pollution poses the highest risks. A recent study from King’s College in London estimated that, in London alone, roughly 9,500 premature deaths each year are linked to high levels of air pollution. After smoking, air pollution is the second-largest public health challenge in the region, researchers say.

12 Aug 2015: Warmer Winters Are Leading to
More Wild Boars in Europe, Research Finds

As Europe experiences more mild winters — very likely an effect of climate change, researchers say — the continent's wild boar

populations are growing exponentially, according to research from the University of Veterinary Medicine - Vienna. The scientists identified the trend by comparing up to 150 years of data on annual boar population growth to temperature and precipitation records from 12 European countries. One factor behind the population surges is body-temperature regulation, the scientists say. In mild winters, wild boars need to use less energy to stay warm, leaving more energy for reproduction and piglet rearing. Another factor is bumper crops of the boars' food sources, primarily acorns and beechnuts, which have become increasingly common over the last few decades. Wild boars are more likely to survive harsh winters if they have been preceded by a good year for their food sources, the researchers note.

according to a report by the Joint Research Center, the European Commission's in-house science service. That's equal to the combined total electricity consumption of Belgium, Ireland, Greece, and the Netherlands, the report notes, and it is a heartening sign for the E.U. wind power sector, which had seen turbine installations decline in 2013. Denmark generated enough wind power to meet 40 percent of its electricity demand, and in Ireland, Portugal, and Spain, wind's share made up between 19 and 25 percent of final consumption. Fifteen other E.U. nations generated 4 percent or more of their electricity from wind. By 2020, wind energy will provide at least 12 percent of Europe's electricity, the analysis says. Globally, wind power has grown dramatically over the last two decades, soaring from 3.5 gigawatts in 1994 to roughly 370 gigawatts by the end of 2014.

01 Jun 2015: Six Major Fossil Fuel Companies
Call for Governments to Set Carbon Price

Six leading oil and gas companies have called on governments to enact a carbon-pricing system, saying this would be the most effective way to cut greenhouse gas emissions. The chief executives of Total, Statoil, Royal Dutch Shell, BG Group, BP, and Eni, in a joint letter to the head of the UN Framework Convention on Climate Change, said that governments should use regulatory measures to discourage carbon-intensive energy options and to level the playing field for all energy sources, both renewables and fossil fuels. The executives said the companies are willing to do their part, but that governments need to provide a clear, stable, and long-term policy framework. Total chief Patrick Pouyanne said in a news conference that a carbon price of roughly $40 per ton is needed to spur the replacement of coal-fired power stations, which produce twice as much CO2 as those that use natural gas. And a price of $80 to $100 per ton, he said, would justify investing in carbon capture and storage systems.

The analysis considered how much cars cost society and how they compare to bicycles in terms of air pollution, climate change, noise, road wear, public health, and congestion in Copenhagen. If the costs to society and the costs to private individuals are added together, the study found, the economic impact of a car is 0.50 euros per kilometer, whereas the cost of a bicycle is 0.08 euros per kilometer. Looking only at costs and benefits to society, one kilometer by car costs 0.15 euros, whereas society earns 0.16 euros on every kilometer cycled because of improvements in the public's health.

08 Apr 2015: Clay Shows Promise in
Capturing CO2 from Power Plants

Common clay can be just as effective as more advanced materials in capturing carbon dioxide emissions from power plants, according to research by Norwegian and Slovak scientists. One particular type of clay mineral, known as smectite, was especially effective in absorbing CO2 emissions, the researchers said in the journal Scientific Reports. One possible use for clay would be to incorporate it into filters or scrubbers in smokestacks at power plants, the scientists said. They said their research into clay’s CO2-absorbing capabilities is preliminary and would not be available for commercial use anytime soon. But the scientists said clay offers many benefits compared to some other expensive and potentially toxic CO2-scrubbing materials.
