Arctic to Experience Temps
40 to 50 Degrees Above Normal This Week
Temperatures near the North Pole are expected to reach nearly 32 degrees F on Thursday — 40 to 50 degrees warmer than average

to several weather models. The warm spell, driven by a powerful storm off the coast of Greenland, comes at the tail end of what is “very likely
” to be the world’s hottest year on record. It also follows an unusually warm November in which the Arctic lost 19,000 square miles of sea ice in just five days. A study published in the journal Nature
earlier this month found such temperature spikes have happened in the Arctic once or twice a decade, dating back to the 1950s. A similar warming event happened at the end of 2015. But the study also found that as sea ice has declined over the last half-century, it has become easier for warm air to move into the region and the intensity of those spikes has worsened.
Interview: Unusually Warm Arctic
May Have Impact on Global Weather
This year will almost certainly go down as the warmest on record in the Arctic, with autumn temperatures soaring 36 degrees F above historic norms.
Among the climate scientists attempting to make sense of the rapid changes sweeping the Arctic is Jennifer Francis of Rutgers University. Francis has propounded the widely discussed theory that swiftly rising temperatures in the Arctic, which are closely intertwined with the loss of sea ice, are changing the shape of the jet stream and altering the weather of the northern hemisphere. In an interview with Yale Environment 360
, Francis explains why large portions of the Arctic are experiencing temperatures more typical of New York City and warns that we ignore climate upheaval at the North Pole at our own peril. "The speed of the change is what is very disturbing to me," says Francis, "because it's such an indicator of what's happening to the planet as a whole."

Soils Could Release 55 Trillion
Kilograms of Carbon By Mid-Century
The world’s soils act as critical storage for carbon, sequestering carbon from the atmosphere to fuel plant and microbial activity.
Permafrost in Greenland.
But scientists warned this week
that as soils warm in response to climate change, they could release 55 trillion kilograms of carbon by mid-century — roughly equivalent to the projected emissions of the United States, or 17 percent of all countries, during that same period. The largest losses will be from high-latitude ecosystems, the new study, led by scientists at the Yale School of Forestry & Environmental Studies and published in the journal Nature
, said. This includes Arctic and sub-Arctic permafrost, where colder temperatures and slow microbial activity have led to the buildup of massive carbon reserves over thousands of years. The scientists found that for every 1 degree Celsius of global warming, soils will release approximately 30 trillion kilograms of carbon into the atmosphere, or twice the annual emissions from human activities.

Freakishly Warm Weather
Is Preventing Sea Ice Formation in Arctic
Scientists are watching with growing alarm as exceptionally warm air and ocean temperatures are effectively holding winter at bay
throughout much of the Arctic, leading to record low sea ice conditions. Researchers in the U.S., Britain, and Denmark say that air temperatures over much of the Arctic Ocean have been about 10 to 20 degrees C (18 to 36 F) above normal this fall, while sea temperatures have been nearly 4 C (7 F) higher than usual in October and November. As a result, sea ice simply isn’t forming in much of the Arctic basin, which further heats up the atmosphere and ocean since dark, open water absorbs far more solar radiation than the reflective white surface of ice and snow. Jennifer Francis of Rutgers University said the region’s temperatures are now “literally off the charts.” Danish satellite remote sensing expert Rasmus Tonboe said the situation in the Arctic is both “surprising and alarming” because sea ice is disappearing faster than climate models had forecast.

Just 1 Degree C of Warming Has
Altered Nearly Every Aspect of Life on Earth
Climate change has already impacted nearly every aspect of life on earth, according to a new study
in the journal Science

Warming global temperatures have altered everything from entire ecosystems down to the individual genes of species. Some 80 percent of key ecological processes examined by the scientists show signs of change and distress. The disruptions could lead to unpredictable fisheries yields, reduced agricultural productivity, worsening pests and disease outbreaks, and “point toward an increasingly unpredictable future for humans,” the authors wrote. "There is now clear evidence that, with only a ~1 degree C of warming globally, very major impacts are already being felt," said lead author Brett Scheffers
, an ecologist at the University of Florida. "Species' physiology and physical features such as body size are changing, species are rapidly moving to keep track of suitable climate space, and there are now signs of entire ecosystems under stress."

Nations Create World’s Largest
Marine Protected Area Near Antarctica
Two dozen nations and the European Union have agreed to set aside 600,000 square miles of ocean for protection near Antarctica,

creating the world’s largest marine park
. The international agreement, which took more than five years to broker, will protect a large portion of the Ross Sea, located in the Southern Ocean. Scientists estimate that the Southern Ocean generates 75 percent of nutrients in the world’s oceans; it is also home to more than 10,000 species. Commercial fishing will be banned in the new marine park for 35 years, though scientists will be able to catch limited krill and other species in designated research zones. "The Ross Sea Region Marine Protected Area will safeguard one of the last unspoiled ocean wilderness areas on the planet — home to unparalleled marine biodiversity and thriving communities of penguins, seals, whales, seabirds, and fish," U.S. Secretary of State John Kerry said in a statement

Arctic Sea Ice Extent in 2016 Ties
As Second Lowest in the Satellite Record
Arctic sea ice extent shrank to 1.6 million square miles earlier this month — tying 2016 with 2007 as the second lowest sea ice minimum since satellite records began.
Sea ice extent in September 2016.
The lowest year remains 2012. The new measurements follow a decades-long trend of declining sea ice extent in the Arctic as global temperatures rise. According to NASA
, “September Arctic sea ice is now declining at a rate of 13.4 percent per decade, relative to the 1981 to 2010 average.” The ten lowest sea ice extents have all happened in the last ten years
. Since 2016 is considered likely to be the warmest year on record, scientists had anticipated an even worse year for sea ice. But “unusually cool, cloudy conditions” in the region for much of the summer helped reduce ice melt, the National Oceanic and Atmospheric Administration said

Newly Discovered Fossils Break
Record, Dating Back 3.7 Billion Years Ago
Geologists have found fossils in Greenland dating back 3.7 billion years — the oldest evidence of life on earth discovered to date. The layers of stromatolites, which are made up of fossilized microbes,
3.7 billion-year-old fossils found in Greenland.
were found in the world’s oldest sedimentary rocks, the Isua supracrustal belt along the edge of the Greenland ice cap. They predate the previous fossil record holder by roughly 220 million years, according to Allen Nutman
, a geologist at the University of Wollongong in Australia and lead author of the new findings, published in the journal Nature
this week. The fossils “indicate that as long as 3.7 billion years ago, microbial life was already diverse,” said Nutman. “This diversity shows that life emerged within the first few hundred millions years of Earth’s existence, which is in keeping with biologists’ calculations showing the great antiquity of life’s genetic code.”

How Elephant Seals Are
Helping Scientists Study Climate Change
A group of southern elephant seals is helping scientists monitor
how climate change is impacting Antarctica by tracking water temperature, depth, and salinity as they swim and dive around the frozen continent.

Most recently, data from the seals — which routinely dive to depths of 1,000 to 2,000 feet — showed that water melting off the Antarctic ice sheet is causing the surrounding seas to become less salty, disrupting a conveyor belt-like system that transfers heat and nutrients around the globe. The new findings were published this week in the journal Nature Communications
. The elephant seal data, as well as records from monitoring devices on other marine mammals, have generated more than 500,000 vertical profiles of temperature and salinity in the world’s oceans and helped inform nearly 100 scientific studies. “"At the moment it's all about filling gaps” in the environmental records, lead author Guy Williams of the University of Tasmania told the Australian Broadcasting Corporation
. “The [seals] have gone to areas where we've never had an observation before."

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.

explore whether the U.S. could covertly deploy ballistic missiles from within the ice sheet, a mission known as Project Iceworm
. By 1967, the military had abandoned the base with little clean up, expecting it would be naturally entombed as snow and ice continued to accumulate on the Greenland ice cap. But warming global temperatures mean that ice loss in this frigid area of northwestern Greenland could exceed gains from new snowfall within 75 years, the study found. The hidden base could be exposed just a few decades later, along with all of the “physical, chemical, biological, and radiological wastes abandoned at the site,” the authors wrote.

, the organization presents five biodiversity hotspots—many of which are at risk from climate change, pollution, over-fishing, and deep-sea mining—worthy of recognition: the Costa Rica Thermal Dome; the White Shark Café, a shark gathering point in the Pacific Ocean; the Sargasso Sea; the Lost City Hydrothermal Field, with its 200-foot carbonate towers, in the Atlantic Ocean; and the Atlantis Bank, a sunken fossil island, in the Indian Ocean.

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

Bacteria in Sea Ice Could Play
Role in Mercury Pollution in Oceans
Scientists have discovered bacteria living in Antarctic sea ice that could play a role in mercury contamination of fish, birds, and other marine species.
Antarctic sea ice.
The bacteria, Nitrospina
, can transform mercury found in sea ice — originating from sources such as coal-fired power plants — into the more toxic methylmercury. The heavy metal pollutant—which impacts brain development and can cause mental and physical ailments—accumulates in higher concentrations in marine life as it moves up through the food chain. The findings were published Monday in the journal Nature Microbiology
by scientists at the University of Melborne, the U.S. Geological Survey, and Lawrence Livermore National Lab. John Moreau, a geomicrobiologist at the University of Melbourne who helped lead the study, said in a statement
that the findings beg further study into the sources and behavior of mercury in the oceans, "particularly in a warming climate and when depleted fish stocks means more seafood companies are looking south."

Changing Arctic Tundra Could
Radically Alter Shorebird Breeding Grounds
A new study projects that global warming could dramatically affect the tundra breeding habitat of 24 shorebird species, with 66 percent to 83 percent losing most of their suitable nesting territories.
Shifts in Arctic shorebirds.
Researchers modeled breeding conditions for these migratory shorebird species — some of which travel more than 10,000 miles from Antarctica or southern South America to breed in the Arctic — and compared projected 21st century conditions to the last major warming event more than 6,000 years ago. The study, published in Global Change Biology
, concluded that a warming and drying tundra could force many species to shift their breeding territories to the Arctic coastline by 2070, causing some birds to completely change their migration routes. “Climate change is also opening up the Arctic to threats such as mining and tourism, and we must make sure we protect key places for all Arctic species, including these amazing migratory birds,” lead author Hannah Wauchope said in a University of Queensland press release

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

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

Sea Ice Hits New Spring Low
In the Arctic, Says Federal Agency
Sea ice extent in the Arctic hit a new record spring low last month, measuring 537,000 square miles below average — an area twice the size of Texas, the National Snow and Ice Data Center announced this week
Sea ice breaking up in the Beaufort Sea in May.
Last month’s Arctic sea ice extent was the lowest May sea ice measurement since satellite monitoring began 38 years ago and follows a string of record low ice this winter. “We didn’t just break the old May record, we’re way below the previous one,” NSIDC Director Mark Serreze told Climate Central
. The Arctic’s snow cover also hit record lows this year, with April having the lowest snow cover for that month on record and May the fourth lowest. The Arctic has warmed twice as fast as the rest of the world in recent decades, but scientists say that this year’s strong El Niño in the Pacific Ocean could be ramping up temperatures even more. Temperatures at the pole have been 4 to 11 degrees F above average
this winter. “Will we end up with very low sea ice extent this September?” Serreze said. “I think pretty much absolutely.”

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.

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."

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.
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.”

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.

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.
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.

Scientists Discover Antarctic
Lake That Could Contain Unique Life Forms
Scientists have discovered what they think is a massive, ribbon-shaped lake under the Antarctic ice sheet that could lead to the discovery of a bevy of new unique life forms.
The lake, which measures 60 miles long by 6 miles wide, was discovered using satellite imagery, and scientists plan to confirm its existence using ice-penetrating radar this spring. The lake has likely been locked under the ice for millions of years — allowing bacteria and other life forms to evolve in complete isolation from the rest of the world, according to a report released at the European Geosciences Union meeting. Unlike the continent’s largest under-ice lake, Vostok, the newly discovered waterbody — located in East Antarctica — is relatively close to a research station, making it easier to explore. “It’s the last un-researched part of Antarctica, so it’s very exciting news,” Bryn Hubbard of the University of Aberystwyth UK told the New Scientist

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
For James Hansen, the Science
Demands Activism on Climate
Climate scientist James Hansen has been a prominent figure in the global climate conversation for more than 40 years. His 1988 congressional testimony on climate change helped introduce the problem of rising greenhouse gas emissions to the American public,
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.”

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.

Half of World Heritage Sites Are
Threatened By Industrial Development
Since 1972, the United Nations has worked to protect 229 locations in 96 countries known for their “exceptional natural beauty” and “cultural significance.” These spots, known as World Heritage Sites,
The Great Barrier Reef
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.
