Unique Stretch Marks Show
Greenland Ice Accelerating Toward Sea
The Greenland ice sheet is accelerating as it flows toward the ocean, and the unique markings visible in this photograph
Crevassing in Greenland ice
are one piece of evidence
demonstrating its rapid movement. Captured as part of NASA's Operation IceBridge
, which is wrapping up its seventh season of Arctic observations, this image details heavy crevassing near the coast of Melville Bay in northwestern Greenland. These fissures are essentially stretch marks on the ice, NASA researchers say. Ice sheets in Greenland and Antarctica are losing mass at an unprecedented rate of 500 cubic kilometers per year — enough ice to cover the Chicago metropolitan area with a layer of ice 600 meters thick — according to
one recent report.

Researchers Discover New
Source of Methane in the Arctic Ocean
A large reservoir of methane — a greenhouse gas many times more potent than carbon dioxide — was recently discovered on
Knipovich Ridge in the Arctic Ocean
Knipovich Ridge in the central Arctic Ocean, according to
research published in the journal Geology
. The methane in this deposit is locked up in icy crystals of water and gas called hydrates, and it was produced by abiotic geological processes rather than by microbes breaking down organic matter, as most methane is, the authors explain. Until now, scientists had not known that hydrates could contain this type of methane. "Up to 15,000 gigatons of carbon may be stored in the form of hydrates in the ocean floor, but this estimate is not accounting for abiotic methane," said co-author Jürgen Mienert. "So there is probably much more."

Melting Arctic Permafrost
To Cause Massive but Gradual CO2 Release
A comprehensive new study of the potential climate change impacts of melting Arctic permafrost says that a vast amount of carbon dioxide will be released from thawing permafrost but that it will seep out gradually,
rather than in an abrupt “carbon bomb.” Working since 2011, a group of 17 Arctic permafrost scientists studied the rate at which permafrost is thawing and the resulting release of CO2. The scientists concluded that Arctic permafrost has undergone a stunning degree of warming, rising from an average of 18 F three decades ago to 28 F today. As permafrost continues to melt, it will release an amount of carbon roughly equal to the carbon released from current rates of deforestation, the study said. The study, published in the journal Nature
, said the CO2 release from thawing permafrost will be prolonged but gradual, giving society time to adapt to rising seas and other impacts of a warming climate.

Bubbling From Melting Glaciers
Makes Fjords Noisiest Places in Oceans
Bubbles gushing from melting glaciers and their icebergs make fjords the noisiest places in the oceans, according to
research published in Geophysical Research Letters
. Researchers used underwater microphones to record noise levels in three bays where glaciers flow into ocean fjords and icebergs calve from glaciers. They found that average noise levels from bubbles in these fjords exceeded those generated by all other sources, including weather, wildlife, and machines such as ships and sonar devices. Glacial calving contributed some of the noise, but the constant melting and bubbling was the real culprit, the researchers said. Their findings raise questions about how the underwater noise in the fjords — which are foraging hotspots for seabirds and marine mammals and important breeding habitat for harbor seals — will affect animals as climate change further increases melting rates.

Warming To Sharply Increase
For Remainder of 21st Century, Paper Says
Within a decade, the earth — and particularly the northern hemisphere — will begin warming at rates unprecedented in the last 1,000 to 2,000 years, according to new research
in the journal Nature Climate Change
. Examining the rate of temperature increases in 40-year intervals over the past 2,000 years, the scientists concluded that temperatures had fluctuated up or down by about 0.2 degrees F over each interval. In the past 40 years, however, warming has approached 0.4 degrees F per decade. And beginning in 2020, temperatures could start to rise by 0.7 degrees F per decade and continue at that rate until at least 2100. Warming will be especially pronounced in the Arctic, where temperatures are expected to soar by 1.1 degrees F by 2040. The scientists warned that such greenhouse gas-driven warming is moving the planet into an unstable climatic state.

Emperor Penguins Had Few
Refuges During Last Ice Age, Study Finds
The Ross Sea and certain other Antarctic waters likely served as refuges for the three emperor penguin populations that
survived during the last ice age, when large amounts of ice made much of the rest of Antarctica uninhabitable, according to a new study
published in the journal Global Change Biology
. The findings suggest that extreme climatic conditions on the continent during the past 30,000 years created an evolutionary "bottleneck" that is evident in the genetic material of modern-day emperor penguins, a species known for its ability to thrive in icy habitats. But during the last ice age, the Antarctic likely had twice as much sea ice, the researchers say, leaving only a few locations for the penguins to breed — distances from the open ocean (where the penguins feed) to the stable sea ice (where they breed) were too great. The three populations that did manage to survive may have done so by breeding near areas of ocean that are kept free of sea ice by wind and currents, the researchers suggest.
As Arctic Ocean Ice Vanishes,
Questions About Future Fishing
With the steady retreat of sea ice in the Arctic Ocean opening up vast areas of this long-frozen marine basin, a key resource
A Russian fishing vessel trawls the Arctic Ocean.
issue is now emerging: the future of fisheries, especially in central Arctic waters. What species are migrating into the region as sea ice disappears? And could the heart of the Arctic Ocean sustain a commercial fishery in the coming decades? These issues were central to a discussion at a recent conference on the fisheries of the central Arctic Ocean. With more southerly fish species migrating into warmer and increasingly ice-free regions of the Arctic Ocean, officials from the U.S. and Canada say it’s important to negotiate an international agreement on fishing before allowing fisheries to open.

Draining of Greenland Lakes
Signals Massive Melting, Researchers Say
Researchers have discovered
craters left behind when two lakes under the Greenland ice sheet rapidly drained recently — an indication
Crater left after a Greenland lake drained.
that a massive amount of meltwater has started overflowing the ice sheet's natural plumbing and is causing "blowouts" that drain lakes away, they say. One of the two lakes once held billions of gallons of water and emptied to form a mile-wide crater in just a few weeks, researchers report in the journal The Cryosphere
. The other lake, described this week in the journal Nature
, was two miles wide and has filled and emptied twice in the last two years. The researchers suspect that as more meltwater reaches the base of the ice sheet, natural drainage tunnels along the Greenland coast are cutting further inland. The tunnels carry heat and water to areas that were once frozen to the bedrock, potentially causing the ice to melt even faster.

Penguin Watch Projects Asks
Citizen Scientists to Monitor Birds' Habits
, a citizen science project launched by researchers from the University of Oxford in the U.K., is enlisting the
Group of Gentoo penguins
public's help in counting penguins in some 175,000 photos from locations across the Southern Hemisphere. Researchers are monitoring five penguin species — Gentoo, Chinstrap, Adelie, Rockhopper, and King penguins — and recording information on the number of adults, chicks, and eggs, as well as their winter behavior, breeding success, and travel habits. The project is especially useful for monitoring penguins' winter behavior, for example, because it's logistically difficult for the researchers to visit these locations in winter, they say
, and the images are far too numerous for researchers to view on their own. Understanding how the penguins live day-to-day should help shed light on how the penguins will respond to an increasingly volatile climate, the team says.

The Arctic Is Absorbing
More and More Sunlight, NASA Images Show
The Arctic has been absorbing significantly more sunlight since the year 2000, according to NASA satellite data
Changes in absorption of sunlight in the Arctic
a trend that mirrors the steady decrease in Arctic sea ice during that same period. These maps show changes in the amount of solar radiation absorbed over the Arctic from 2000 to 2014, as well as changes in sea ice cover during the same period. As sea ice cover declines and more dark ocean is exposed to the sun's rays, that decreases the reflectivity, or albedo, of the ocean's surface, meaning more heat is absorbed. Shades of red depict areas absorbing more sunlight and areas with less ice cover. The Arctic's rate of absorption has increased by 5 percent every June, July, and August since 2000. No other region on the planet has shown significant changes in albedo during that time, researchers say.

Weather and Climate Key in Weights of Penguin Chicks, Researchers Say
Local weather and large-scale climate trends have the largest impact on the weights of Adélie penguin chicks
An adult Adélie penguin feeds its chick.
— not food availability — according to
researchers at the University of Delaware. Adélie penguins are native to the West Antarctic Peninsula, and their habitat is warming faster than most other parts of the planet. Looking at records dating back to 1987, scientists found that year-to-year changes in local weather — including wind speed, temperature, rain, and humidity — could cause chicks’ weights at the time they leave their nests to fluctuate by up to 7 ounces. That’s often the difference between a surviving and non-surviving chick, the researchers say. Biologists previously thought that food sources and parenting played the largest role in chicks’ health, but these findings
suggest that exposure to elements is more important. The study "calls into question what happens to an ecosystem when you change climate quickly," principal investigator Matthew Oliver said.

Antarctica and Greenland
Losing Ice at Fastest Rate Ever Recorded
Ice sheets in Greenland and Antarctica are losing mass at an unprecedented rate of 500 cubic kilometers per
year — enough ice to cover the Chicago metropolitan area with a layer of ice 600 meters thick — according to
German researchers. Using data from the European Space Agency's CryoSat 2 satellite from 2011 to 2014, the team created the most detailed maps to date of ice elevations across Antarctica and Greenland, accurate to a few meters in height. The results reveal that Greenland alone is losing ice volume by about 375 cubic kilometers per year, doubling since 2009, the scientists report. Ice loss in the West Antarctic Ice Sheet has increased by a factor of three over the same period. Combined, the two ice sheets are thinning at the highest rate observed since altimetry satellite records began about 20 years ago, the study found. Data show that East Antarctica is gaining ice volume, but at a moderate rate that doesn’t compensate the losses on the continent's other side.

Antarctica's Emperor Penguins
To Be in Serious Decline By 2100, Study Says
Antarctica's Emperor penguins are facing dramatic declines by the end of the century and should be given endangered species status because of the threats posed
Sea ice loss threatens Emperor penguins.
by climate change, according to
an international group of scientists. If sea ice declines at the rates projected by current climate models, at least two-thirds of the colonies will likely shrink by more than 50 percent by 2100, the researchers report in Nature Climate Change
. That conclusion follows a 50-year study in eastern Antarctica of Emperor penguins, an iconic Antarctic species with 45 known colonies. Emperor penguins' survival is highly dependent on sea ice concentrations because they breed on the ice, and too little sea ice reduces the habitat for krill, a critical food source for the penguins. Granting the species protected status under the U.S. Endangered Species Act will provide tools for improving fishing practices of U.S. vessels in the Southern Ocean and potentially for reducing CO2 emissions in the U.S. under the Clear Air Act, the researchers say.

Skyscraper-Size Ice Structures
Discovered at Base of Greenland Ice Sheet
Melting and refreezing at the base of the Greenland ice sheet has created massive, complex structures the height of skyscrapers and the width of Manhattan, according to
research published in Nature Geoscience
The hidden formations more than a mile below the surface stand in stark contrast to the nearly flat, smooth exterior of the ice sheet and may accelerate its flow toward the sea, researchers say. Scientists had previously interpreted the irregular topography at the base of the ice as hills or mountains, but ice-penetrating radar revealed that the structures were made of ice rather than rock. Scientists from Columbia University explained that as meltwater at the bottom refreezes over hundreds or thousands of years, it radiates heat into the surrounding ice sheet, making it pick up its pace as the ice becomes softer and flows more easily. Greenland's glaciers appear to be moving more rapidly toward the sea as climate warms, but it's unclear how the refreezing process will influence this trend, researchers said.

Widespread Greenland Melting
Due to Forest Fires and Warming, Study Says
Rising temperatures and ash from Northern Hemisphere forest fires combined to cause large-scale surface melting of the Greenland ice sheet in 2012, an
echo of a similar event that occurred in 1889, a new study
finds. The massive Greenland ice sheet — the second largest ice body in the world after the Antarctic ice sheet — experiences annual melting at low elevations near the coastline, but surface melt is rare in the dry snow region in its center. In July 2012, however, satellites observed for the first time surface melt across more than 97 percent of the ice sheet, generating reports that the event was almost exclusively the result of climate change. In the new report, published in the journal Proceedings of the National Academy of Sciences
, researchers found that in both 2012 and 1889 exceptionally warm temperatures combined with black carbon sediments from Northern Hemisphere forest fires to darken the surface of the ice sheet to a critical albedo threshold, causing the large-scale melting events. Since Arctic temperatures and the frequency of forest fires are both expected to rise with climate change, large-scale melt events on the Greenland ice sheet may begin to occur almost annually by 2100, the researchers say.
Interview: Can Marine Life Adapt
To the World’s Acidifying Oceans?
As the world’s oceans grow more acidic from increased absorption of atmospheric carbon dioxide, marine scientists are confronting a key question: How well can
organisms like mollusks, crustaceans, and corals adapt to these more corrosive conditions? One of the leading authorities in this field is University of California, Santa Barbara marine biologist Gretchen Hofmann. Her work in recent years has shown, in fact, that some sea organisms that build shells do seem to have some ability to acclimate to more acidic waters. But in an interview with Yale Environment 360
, Hofmann cautions that this adaptive capacity has its limits. The continuing burning of fossil fuels, she says, could push ocean acidity past a tipping point, rendering some mollusks and other organisms unable to build shells.

Natural Variations May Account
For Up to Half of Greenland's Warming
Up to half of the recent climate change in Greenland and surrounding regions — which have warmed at roughly twice the pace of the rest of the planet since 1979 — may be due to natural climate variations that originate in the tropical Pacific and are not connected
Meltwater from Russell Glacier
with the overall warming of the Earth, a new study
says. Still, at least half the warming remains attributable to rising global carbon dioxide emissions, according to research published in the journal Nature
. Climate data and advanced computer models show that changes in the western tropical Pacific Ocean, which has been about 0.3 degrees warmer than normal, have caused shifts in atmospheric pressure over the North Atlantic. Those changes set off a stationary wave in the atmosphere that arcs in a great circle from the tropical Pacific toward Greenland, pulling warmer air over that massive island. "Along this wave train there are warm spots where the air has been pushed down, and cold spots where the air has been pulled up," one author explained. "And Greenland is in one of the warm spots."
Carries on in Key Arctic Ecosystem
At a time of rapidly deteriorating relations between Russia and America, U.S. scientist Joel Berger continues his work with his Russian counterparts
Third in a series of blog posts from the Russian Arctic
on Siberia's Wrangel Island. In the third of three blog posts for Yale Environment 360
, Berger — a biologist with the Wildlife Conservation Society and the University of Montana — writes about efforts to better understand how rapid climate change might affect muskoxen and other wildlife in the Russian and North American Arctic. As Berger explains, a key focus of Russian-American scientific cooperation is Beringia, the region of northwestern Alaska and extreme northeastern Russia where two countries — and continents — are divided by the Bering Sea.

Exxon Mobil Arctic Project
Possibly At Risk Over Russia Sanctions
Exxon Mobil's development of a Russian Arctic oil project valued at nearly $900 billion is at risk following recent U.S. sanctions on Russian officials as a result of Ukraine's ongoing political crisis, Bloomberg News reports
. Exxon Mobil has partnered with the Russian state-controlled oil company OAO Rosneft to drill an oil-rich geological structure known as Universitetskaya, which contains an estimated 9 billion barrels of oil, valued at $900 billion at current market prices. Rosneft's CEO, Igor Sechin, a longtime member of Russian President Vladimir Putin's inner circle, was sanctioned by the U.S. yesterday, exposing the partnership with Exxon Mobil to additional scrutiny. Exxon Mobil and Rosneft are set to invest an estimated $600 million in drilling at the site in the Kara Sea, which would make the project Exxon's most expensive to-date. A U.S. Treasury official said yesterday that U.S. companies can still do business with Rosneft, but some analysts say Russian companies could become wary of working with Western corporations in the future. Exxon said last week that the project is on schedule.

Newfound Atmospheric 'Hole'
Threatens Polar Ozone Layer, Scientists Say
Researchers have discovered
a large opening in the Earth's atmosphere that is enabling pollutants to rise
Pacific atmosphere hole an elevator to the stratosphere
into the stratosphere and destroy ozone. The hole, which is in a part of the lower atmosphere called the "OH shield," is several thousand kilometers long and is centered over the tropical west Pacific Ocean. It's relatively close to Southeast Asia, a region with a booming population and rapidly increasing air pollution. The hole is a major concern because the OH shield usually scrubs air of chemical compounds emitted near the ground before they can reach the stratosphere, where those compounds can persist for long periods of time, reacting with and destroying ozone, say researchers at Germany's Alfred Wegener Institute who identified the hole. The newly discovered phenomenon acts as a sort of elevator, researchers say, drawing chlorofluorocarbons, sulfur dioxide, and other contaminants straight up to the stratosphere and bypassing the OH shield scrub.

West Antarctic Glacial Loss
Is Rapidly Intensifying, New Study Shows
Six massive glaciers in West Antarctica are dumping far more ice into the Southern Ocean than they were 40
An 18-mile crack in the Pine Island Glacier
years ago and now account for 10 percent of the world’s sea level rise
, according to a new study. Reporting in Geophysical Research Letters
, an international team of scientists said that the amount of ice draining from the six glaciers has increased by 77 percent since 1973. The scientists said that the ice loss from the six glaciers is so substantial that it equals the amount of ice draining annually from the entire Greenland Ice Sheet. The scientists used satellite data from 1973 and 2013 to gauge the ice loss from the six glaciers. The Pine Island Glacier
is moving more rapidly to the sea than any of the other six, with its speed increasing from 1.5 miles per year in 1973 to 2.5 miles per year in 2013. The glaciers are dumping more ice into the sea primarily because warmer ocean waters are loosening the ice sheets’ hold on the sea floor, which speeds up glacial flow.

Warm River Water Plays Major
Role in Arctic Sea Ice Melt, Study Finds
Relatively warm water flowing into the Arctic Ocean from rivers contributes significantly to Arctic sea ice melt each summer, a phenomenon that will intensify as the region warms, according to NASA researchers
. The river discharge not only melts coastal sea ice, it also has
a wider climate impact as it creates more open water, which is darker than ice and absorbs more heat from sunlight. As these NASA images show, when water from Canada's Mackenzie River flowed into the Beaufort Sea in the summer of 2012, average surface temperature of the open water rose by 6.5 degrees C (11.7 degrees F) after the pulse of river water. Flow from the Mackenzie raised sea surface temperatures as far as 350 kilometers (217 miles) from the coast. The researchers note that river discharge is becoming an increasingly important contributor to melting Arctic sea ice because the volume and temperature of fresh water discharge is increasing as inland Arctic areas warm more each summer.

Loss of Arctic Sea Ice
Has Greater Warming Impact Than Expected
The steady disappearance of Arctic sea ice, which is causing the exposed and darker surface of the Arctic Ocean to absorb more sunlight, is having a more profound impact on global warming
estimated, according to a new study. The decline of albedo, or reflectivity, from the Arctic Ocean equals roughly 25 percent of the warming caused by rising carbon dioxide levels, according to scientists at the University of California, San Diego. The impact of this "albedo feedback," in which the highly reflective white surface of sea ice is replaced by heat-absorbing open ocean, is considerably stronger than climate models had predicted, according to the UCSD research
, published in the Proceedings of the National Academy of Sciences.
Researchers had thought increasing Arctic cloud cover might slow the albedo feedback, but this study indicates that is not happening.

NASA Image of Alaska
Depicts Spring-like Temperatures and Thaw
As the continental U.S. faced frigid weather and major winter storms in January, Alaska experienced record high temperatures.
A map based on NASA satellite data
shows that the last half of January was one of the warmest winter periods in Alaska’s history, with temperatures as much as 40 degrees F (22 C) above normal on some days in the central and western portions of the state. A high pressure system off the state's western coast sent warm air and rain through Alaska instead of down into California, which is in the midst of a record drought. The warmest January temperature ever observed in Alaska was tied on January 27, when the thermometer hit 62 F (16.7 C) at Port Alsworth, in southern Alaska. Combined with rainstorms, the heatwave set off a host of spring-like effects, including avalanches and swollen rivers, which carried major sediment loads into the Gulf of Alaska. Inland, Arctic lakes are also seeing consequences of Alaska's long-term warming trend. A new study
found that lakes in the region froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared to the winter of 1950.
Interview: Activist Kumi Naidoo
On Russia and the Climate Struggle
Kumi Naidoo, the international executive director of Greenpeace, is intimately familiar with the Prirazlomnaya drilling platform in the Russian Arctic. In 2012, he and five other Greenpeace activists were hosed down with frigid water and pelted with pieces of metal as they attempted to climb aboard the platform.
Greenpeace and Prirazlomnaya were back in the news recently when 28 Greenpeace members were arrested and held for several months for storming the rig before being released in December. In an interview with Yale Environment 360
, Naidoo talks about what’s needed to get global climate talks off the ground and launch a green energy revolution, and the reason his activist organization has decided to take such a strong stand against oil drilling in the rapidly melting Arctic Ocean. "We went back [to Prirazlomnaya]," says Naidoo, "because we’re trying to draw a line in the ice, because once this starts it will have breached another threshold of meeting our rapacious appetite for oil and gas in the most fragile of environments." Read the interview.

Pine Island Glacier Has
Melted Beyond Tipping Point, Study Says
A major Antarctic ice mass, the Pine Island Glacier, is melting irreversibly and could add as much as a centimeter to global sea level rise over the next 20 years alone, according to new research published in Nature Climate Change
. Calculations show that the Pine Island Glacier's "grounding line" — where land-based ice meets a floating ice shelf that is an extension of the
glacier — has retreated roughly 10 kilometers in the past decade. Scientists say that the grounding line is in the process of a 40-kilometer retreat that could push it beyond an important tipping point. Pine Island Glacier is a major contributor to global sea level rise
and has been losing massive amounts of ice for decades, accounting for 20 percent of the West Antarctic Ice Sheet's total ice loss
. An international research team says that the Pine Island Glacier has been losing 20 billion tons of ice annually for the past two decades and could lose 100 billion tons annually over the next 20 years. The glacier "has started a phase of self-sustained retreat and will irreversibly continue its decline," says Gael Durand, a glaciologist with France's Grenoble Alps University.

Faced With Sea Ice Loss,
Emperor Penguins Alter Breeding Tactics
Confronted with the loss of sea ice in some parts of Antarctica, four colonies of emperor penguins have come up with an innovative breeding strategy
to adapt to their changing environment. Using satellite images,
an international team of scientists tracked the four colonies from 2008 to 2012. In the first three years, the emperor penguins hatched and incubated eggs in their customary fashion — atop the sea ice that freezes during the Antarctic winter and spring. But in 2011 and 2012, sea ice did not form until a month after the breeding season began. As a result, the emperor penguins, which are the largest penguin species on earth, did something never before witnessed by scientists: They climbed the nearly sheer walls of large, floating ice shelves — huge structures, often hundreds of square miles in extent, that flow from land-based glaciers into the sea. In the region of the four colonies, the ice shelf walls reach as high as 100 feet. The scientists say the altered breeding behavior could demonstrate how ice-dependent emperor penguins may adapt to a warming world.

Stranded Antarctic Expedition
Rescued After Being Icebound for Nine Days
Passengers trapped on an icebound Russian research ship off the coast of Antarctica were rescued today after being stranded
for more than a week. A helicopter from China shuttled the 52 scientists, journalists, and tourists to an Australian icebreaker. The chartered ship was attempting to recreate the century-old travels and scientific work carried out by the East Antarctic research expedition led by Douglas Mawson in 1911. The Russian ship, which set out from New Zealand on December 8, became trapped in thick pack ice that even icebreakers could not penetrate. Because it was a privately chartered expedition, the voyage was not subjected to the same rigorous safety requirements that a research trip funded by government agencies would have been, scientists said. Some scientists contended that the lack of preparation sparked a rescue effort that diverted ships, crew, and other important resources
from other research efforts elsewhere in Antarctica.
