24 May 2016: Peru Declares Emergency to
Fight Mercury Pollution from Gold Mines

Peru has declared a 60-day emergency in the Amazon due to widespread mercury pollution from the region’s booming gold mining industry, the country's environment minister announced this week.

Several studies have confirmed dangerously high levels of the neurotoxin in waterways, fish, and people living in the Madres de Dios region, near Peru’s southeast border. Members of the Harakmbut indigenous group, for example, have mercury levels in their bodies six times higher than what doctors deem safe. Mercury is used to separate gold from ore, but it can have serious health impacts, including damaging brain, kidney, and lung function. In illegal mining operations — which make up the majority of mines in the Peruvian Amazon — workers often handle the substance with bare hands, and dump excess mercury into nearby rivers. During the 60-day emergency period, the government will supply uncontaminated fish to local communities and set up mobile health clinics.

23 May 2016: 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.

NASA
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."

12 May 2016: 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.

10 May 2016: More than 2,000 New
Plant Species Are Found Every Year

There are currently 391,000 plant species known to science—and another 2,000 are being discovered every year, according to a new report from the U.K.’s Royal Botanic Gardens, Kew.

Paulo Gonella
Last year’s new discoveries included a nearly five-foot tall carnivorous plant first identified on Facebook, a 105-ton tree in West Africa, and 90 new species of Begonia flowers. Brazil, Australia, and China were hotspots for species discovery. The State of the World’s Plants report did find, however, that one-fifth of the world’s plant species are at risk of extinction from habitat loss, disease, invasive species, and climate change. “Plants are absolutely fundamental to humankind,” Kathy Willis, director of science at Kew, told The Guardian. “Plants provide us with everything — food, fuel, medicines, timber, and they are incredibly important for our climate regulation. We are facing some devastating realities if we do not take stock and re-examine our priorities and efforts.”

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.

Brian Gratwicke/Flickr
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.

02 May 2016: After a Decade of Decline,
Brazil's Deforestation Again on the Rise

Brazil is losing two soccer field-sized parcels of rainforest every minute, equal to 1,930 square miles annually, according to new reporting from the Thompson Reuters Foundation.

Matt Zimmerman/Flickr
The trend represents a significant blow to Brazil’s decades-long fight against illegal logging activity, which achieved an 80 percent decline in deforestation from 2003 to 2013 due to aggressive government and civil monitoring of the forests. But these efforts have slackened in recent years, and loggers have changed their tactics to better hide their activities, said Tasso Azevedo, a conservationist and former director of the Brazilian Forest Service. "In some cases, we are walking backwards," he told Thompson Reuters. The uptick could pose a challenge to pledges Brazil made during international climate talks in Paris last December. The country promised to eliminate illegal deforestation and restore nearly 30 million acres of forest by 2030 to combat global warming.

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.”

From Mass Coral Bleaching,
A Scientist Looks for Lessons

Twice a year, Georgia Tech climate scientist Kim Cobb travels to Christmas Island in the middle of the Pacific Ocean to collect samples from coral reefs to better understand past and future climate change.

But when Cobb arrived on the island earlier this month, she was stunned. The corals she had spent the past 18 years studying were largely dead or dying. The scene has become a familiar one across the Pacific and Indian oceans this year as a record-breaking El Niño drove up water temperatures and caused fragile coral reef systems to bleach from stress or die. In an interview with Yale Environment 360, Cobb talked about the recent bleaching event, the race to make reefs more resilient, and how coral records could improve short-term climate projections. “What you think reefs might be experiencing in 20 years,” she says, “they're experiencing now.”

22 Apr 2016: Brazilian Officials Put a
Hold on Mega-Dam Project in the Amazon

A proposed 8,000-megawatt hydroelectric dam in the Amazon was put on hold this week by Brazil’s environmental agency out of concerns over its impact on a local indigenous tribe.

The São Luiz do Tapajós project — which would be Brazil’s second-largest dam and a cornerstone of government efforts to expand hydroelectric power — would require developers to flood an area the size of New York City and home to thousands of Munduruku people. The environmental agency, Ibama, said they were suspending the project’s licensing because of “the infeasibility of the project from the prospective of indigenous issues.” Brent Millikan, the Amazon program director for International Rivers, told Reuters, "The areas that would have been flooded include sites of important religious and cultural significance. The local communities have a huge amount of knowledge about the resources where they are — if they were forced off the land and into cities they would become unskilled workers."

21 Apr 2016: A Town Made Almost Entirely Out
Of Plastic Bottles is Being Built in Panama

Construction has begun on the world’s first town made almost entirely out of recycled plastic bottles. Located on Isla Colón in Panama, the village will consist of 120 houses and a lodge on 83 acres of tropical jungle.

The first two-bedroom home was built late last year, and is made from 10,000 plastic bottles pulled from Panama trashcans, roadsides, and beaches. The walls of the homes consist of steel cages filled with bottles and then encased in a concrete mix. They are flexible enough to withstand an earthquake, and insulating enough to keep the home up to 17 degrees F cooler than the jungle outside. Because there are so many recycled bottles on the island already, homes can be built quickly and cheaply, said Robert Bezeau, founder of the Plastic Bottle Village. “We are changing the world, without changing the Earth, one home at a time,” he says on the project’s website.

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 new tree of life.
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.

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.

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.

05 Apr 2016: El Nino Prevents Phytoplankton
Growth, Endangering Marine Food Web

El Nino—the cyclical warming of the Pacific Ocean—has wreaked havoc on the world’s weather for the past two years, from a record-breaking number of cyclones in the North Pacific to flooding in South America.

Satellite images of phytoplankton growth.
But scientists at NASA recently discovered that the climate phenomenon also has a big impact on phytoplankton, the tiny oceanic organisms that serve as the base of the marine food chain. Normally, ocean currents drive cold, deep water to the surface near the equator, bringing with it a flood of nutrients that feed phytoplankton. El Nino’s mass of warm water stops this upwelling. The result is a marked drop in phytoplankton levels. “This decline echoes through many species,” said Stephanie Uz, an ocean scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland who led the study. “Small fish that feed on phytoplankton starve. This affects everything from penguin and iguana populations in the Galapagos to governments managing fisheries.”

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.

Grown in the Wild for the First Time

Caribbean coral colonies bred in a lab, using in-vitro fertilization, have for the first time been raised to sexual maturity in their

natural marine habitat, according to findings published in the Bulletin of Marine Science. Offspring of endangered elkhorn coral were reared from gametes collected in the field and successfully reattached to a reef a year later, where they have grown in size considerably according to researchers from SECORE International. Over the past four decades, an estimated 80 percent of all Caribbean corals have disappeared. The elkhorn coral’s decline is so severe that it was the first coral species to be listed as threatened under the U.S. Endangered Species Act in 2006. Due to its large size, branching shape, and preference for shallow waters, the coral is particularly effective at protecting shorelines from incoming storms, as well as providing a critical habitat for many reef organisms. Scientists hope this success will be an important step in helping restore endangered reefs.

11 Jan 2016: Scientists Warn of Biodiversity
Impacts of Major Hydropower Projects

Hydropower is considered by many to be a key ingredient to reducing carbon emissions and meeting global climate goals,

but it comes at a great cost to biodiversity, particularly in tropical rainforests, according to a new report published in the journal Science. “Far too often in developing tropical countries, major hydropower projects have been approved and their construction begun before any serious assessments of environmental and socioeconomic impacts had been conducted,” says the report's lead author Kirk Winemiller, an aquatic ecologist at Texas A&M University. The dam-building rush, with more than 450 dams planned for the Amazon, Congo, and Mekong river basins alone, impedes tropical fish migration and vastly expands deforestation due to road construction, according to the authors. Other concerns include development of previously inaccessible terrain, as well as methane emissions from newly built reservoirs.

26 Oct 2015: Major Clue Emerges in Mystery
Of Right Whale Deaths, Researchers Say

Endangered right whales, especially young calves of the southern population, have been having a hard time in recent years, and

Southern right whale and calf near Peninsula Valdes
scientists haven't been able to determine why. For example, the average number of right whale deaths per year at Peninsula Valdes, a breeding ground off central Argentina's Atlantic coast, jumped more than 10-fold from 2005 to 2014 — from fewer than six per year to 65 per year, researchers say. Roughly 90 percent of the deaths were calves fewer than three months old. Now researchers have closed in on a suspect: blooms of a type of algae known as Pseudonitschia, which produce harmful neurotoxins, the researchers write in the journal Marine Mammal Science. Scientists from the United States and Argentina found that the number of whale deaths at the peninsula closely tracked the concentrations of the toxic algae, offering strong circumstantial evidence that the algal blooms are likely behind the whale deaths.

04 Sep 2015: Maya Permanently Altered Land
To Respond to Climate Change, Study Says

Mayan activity more than 2,000 years ago contributed to the decline of Central America's tropical lowlands and continues to influence the land and environment today, say researchers at the University of Texas at Austin. Evidence shows that during the "Mayacene" — a period from 3,000 to 1,000 years ago when humans began greatly affecting the environment — the Maya's advanced urban and rural infrastructure altered tropical forest ecosystems. Clay and soil sequences indicate erosion and land-use changes, and sediments near wetlands reveal chemical signatures of agriculture, says the study, which was published in the journal Quaternary Science Reviews. The researchers say features such as constructed wetlands, vast field systems, and terraces show that the Maya managed land and water to adapt to climate change and rising sea levels. "Though it has no doubt accelerated in the last century, humans' impact on the environment has been going on a lot longer," said lead researcher Tim Beach.

Brazil and Indonesia, the two countries most often associated with deforestation, had been making gains toward stemming the problem, but 2014 saw an uptick in tree cover loss in both countries. The situation is especially concerning in Cambodia, where deforestation is accelerating faster than anywhere else in the world due to the development of rubber plantations. Last year Cambodia lost three times more tree cover than in 2001, the analysis found.
