Northeast Greenland ice loss accelerating, researchers say (March 16, 2014) -- The last remaining stable portion of the Greenland ice sheet is stable no more, an international team of scientists has discovered. The finding will likely boost estimates of expected global sea level rise in the future. The new result focuses on ice loss due to a major retreat of an outlet glacier connected to a long "river" of ice -- known as an ice stream -- that drains ice from the interior of the ice sheet. The Zachariae ice stream retreated about 20 kilometers (12.4 miles) over the last decade, the researchers concluded. For comparison, one of the fastest moving glaciers, the Jakobshavn ice stream in southwest Greenland, has retreated 35 kilometers (21.7 miles) over the last 150 years. ... > full story

 

Big thaw projected for Antarctic sea ice: Ross Sea will reverse current trend, be largely ice free in summer by 2100 (February 27, 2014) -- A new modeling study suggests that a recent observed increase in summer sea-ice cover in Antarctica's Ross Sea is likely short-lived, with the area projected to lose more than half its summer sea ice by 2050 and more than three quarters by 2100. These changes will significantly impact marine life in what is one of the world's most productive and unspoiled marine ecosystems. ... > full story

Greenland ice is melting -- even from below: Heat flow from the mantle contributes to the ice melt (August 11, 2013) -- The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, there is an increased heat flow from the mantle and a complex interplay between this geothermal heating and the Greenland ice sheet. New research finds that this effect cannot be neglected when modeling the ice sheet as part of a climate study. ... > full story

Carbon dioxide at NOAA's Mauna Loa Observatory reaches new milestone: Tops 400 parts per million (May 10, 2013) -- On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958. Independent measurements made by both NOAA and the Scripps Institution of Oceanography have been approaching this level during the past week. It marks an important milestone because Mauna Loa, as the oldest continuous carbon dioxide measurement station in the world, is the primary global benchmark site for monitoring the increase of this potent heat-trapping gas.

 

Ice-free Arctic may be in our future, international researchers say (May 9, 2013) -- Analyses of the longest continental sediment core ever collected in the Arctic provide "absolutely new knowledge" of Arctic climate from 2.2 to 3.6 million years ago. The research has major implications for understanding how the Arctic transitioned from a forested landscape without ice sheets to the ice- and snow-covered land we know today.

 

New insight into accelerating summer ice melt on the Antarctic Peninsula (April 14, 2013) -- A new 1,000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost 10-fold, and mostly since the mid-20th century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers.  

 

Recent Antarctic climate, glacier changes at the 'upper bound' of normal (April 14, 2013) -- In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise. New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming

 

Arctic nearly free of summer sea ice during first half of 21st century, experts predict (April 12, 2013) -- For scientists studying summer sea ice in the Arctic, it's not a question of "if" there will be nearly ice-free summers, but "when." And two scientists say that "when" is sooner than many thought -- before 2050 and possibly within the next decade or two.

 

Warmest summers in last two decades in northern latitudes were unprecedented in six centuries (April 11, 2013) -- Through developing a statistical model of Arctic temperature and how it relates to instrumental and proxy records derived from trees, ice cores, and lake sediments, scientists have shown that the warmest summers in the last two decades are unprecedented in the previous six centuries.

 

2013 wintertime Arctic sea ice maximum fifth lowest on record (April 3, 2013) -- During the cold and dark of Arctic winter, sea ice refreezes and achieves its maximum extent, usually in late Feb. or early Mar. According to a NASA analysis, this year the annual maximum extent was reached on Feb. 28 and it was the fifth lowest sea ice winter extent in the past 35 years.

 

Thin clouds drove Greenland's record-breaking 2012 ice melt (April 3, 2013) -- If the sheet of ice covering Greenland were to melt in its entirety tomorrow, global sea levels would rise by 24 feet. Three million cubic kilometers of ice won't wash into the ocean overnight, but researchers have been tracking increasing melt rates since at least 1979. Last summer, however, the melt was so large that similar events show up in ice core records only once every 150 years or so over the last four millennia.

Scientists team with U.S. Coast Guard to explore ice-free Arctic Ocean (October 2, 2012) -- With the melting ice in the Arctic, U.S. Coast Guard crews based in Alaska have taken on a new challenge: carefully deploying scientific equipment through cracks in the ice from an airplane hundreds of feet in the air. It's all part of a new partnership that has evolved since disappearing Arctic ice has opened vast new frontiers -- for the Coast Guard and for University of Washington scientists. This year, the lowest ebb of Arctic sea ice covered less area than at any time since scientists began recording it. From 1979 to 2000, the average low point for the year was 7 million square kilometers, or 2.7 million square! miles. This year, it's less than half as much -- 3.4 million square kilometers.  

 

Arctic sea ice shatters previous low records; Antarctic sea ice edges to record high (October 3, 2012) -- This September, sea ice covering the Arctic Ocean fell to the lowest extent in the satellite record, which began in 1979. Satellite data showed that the sea ice cover reached its lowest extent on September 16. Sea ice extent averaged for the month of September was also the lowest in the satellite record. As the Arctic was experiencing a record low minimum extent, the Antarctic sea ice was reaching record high levels, culminating in a Southern Hemisphere winter maximum extent of 19.44 million square kilometers (7.51 million square miles) on September 26.

Summer storm spins over Arctic (August 10, 2012) -- An unusually strong storm formed off the coast of Alaska on August 5 and tracked into the center of the Arctic Ocean, where it slowly dissipated over the next several days. Arctic storms such as this one can have a large impact on the sea ice, causing it to melt rapidly through many mechanisms, such as tearing off large swaths of ice and pushing them to warmer sites, churning the ice and making it slushier, or lifting warmer waters from the depths of the Arctic Ocean.  

 

Earth's oceans and other ecosystems still absorbing about half the greenhouse gases emitted by people (August 1, 2012) -- Earth's oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a new study. The scientists analyzed 50 years of global carbon dioxide measurements and found that the processes by which the planet's oceans and ecosystems absorb the greenhouse gas are not yet at capacity.

 

New discovery of how carbon is stored in the Southern Ocean (July 29, 2012) -- Scientists have discovered an important method of how carbon is drawn down from the surface of the Southern Ocean to the deep waters beneath.

Why climate models underestimated Arctic sea ice retreat: No Arctic sea ice in summer by end of century? (October 12, 2011) -- In recent decades, Arctic sea ice has suffered a dramatic decline that exceeds climate model predictions. The unexpected rate of ice shrinkage has now been explained. Researchers argue that climate models underestimate the rate of ice thinning, which is actually about four times faster than calculations. This model bias is due to the poor representation of the sea ice southward drift out of the Arctic basin through the Fram Strait. When this mechanism was taken into account to correct the discrepancy between simulations and observations, results from the new model suggested that there will be no Arctic sea ice in summer by the end of the century. ... > full story

Study Says Carbon Dioxide Making Oceans More Acidic.

http://www.sciencedaily.com/releases/2010/04/100420152841.htm

The AP (4/23) reports, "The chemistry of the oceans is changing faster than it has in hundreds of thousands of years because of the carbon dioxide being absorbed from the atmosphere," according to a study (pdf) from the National Research Council. "The chemicals make the water more acidic, which can affect sea life. Since the beginning of the Industrial Revolution in the 18th century, the pH of ocean water has declined from 8.2 to 8.1 and a further decline of 0.2 to 0.3 units is expected by the end of this century," the study predicts.

        The Los Angeles Times (4/22, Mohan) "Greenspace" blog reported, "Oceans worldwide are turning increasingly acidic as they absorb more carbon from the atmosphere, which could have negative effects on many forms of marine life at the base of the oceanic food chain, including plankton, coral and large mollusks such as oysters." Greenspace noted, "Little is known about the long-term effects of a more acidic ocean, but studies have shown acidification affects many biological processes, including photosynthesis, nutrient uptake, growth and reproduction."

NASA Plans Large Increase To Climate Research Budget.

The Washington Post (4/1, A5, Kaufman) reports, "NASA officials laid out plans Wednesday to boost spending on climate research substantially over the next five years, to make up for cutbacks during the Bush administration." NASA Associate Administrator Ed Weiler announced the Earth Science budget will increase over 60% by 2015. "The budget increase reflects both a campaign promise by President Obama to focus far more on the threat of climate change and what NASA officials called a 'philosophical shift' on the issue. From now on, they said, the agency will place a higher priority on collecting a broad range of interrelated climate data." The additional money will be used for "improvements, innovations and replacements" of older missions. According to the article, the rise in the Earth Science budget "contrasts with the generally flat budgets projected for other NASA missions."

EPA: Carbon Dioxide A Danger To Public Health.

The Wall Street Journal (3/24, Talley) reports the Environmental Protection Agency has submitted a proposed finding to the White House indicating that "carbon dioxide is a danger to public health, a step that could trigger a clampdown on emissions of greenhouse gases across a wide swath of the economy." Were the White House to approve the finding, the EPA could "use the Clean Air Act to control emissions of carbon dioxide and other greenhouse gases believed to contribute to climate change," and "raise pressure on Congress to enact a system that caps greenhouse gases."

        The AP (3/24, Hebert) reports the White House has indicated it will "move cautiously when it comes to actually regulating greenhouse gases, preferring to have Congress act on the matter." White House Press Secretary Robert Gibbs said, "I think this is just the step in [the] process" of determining whether emissions should be regulated under the Clean Air Act. Another White House official suggested it would be "'a long process' before any rules would be expected to be issued on heat-trapping emissions."

        The Washington Post (3/24, A1, Eilperin) reports on the front page that White House spokesman Ben LaBolt stressed, "The president has made clear that to combat climate change, his strong preference is for Congress to pass energy security legislation that includes a cap on greenhouse gas emissions. The Supreme Court ruled that the EPA must review whether greenhouse gas emissions pose a threat to public health or welfare, and this is simply the next step in what will be a long process that engages stakeholders and the public." The Detroit News (3/23, Shepardson), the Los Angeles Times (3/24, Eilperin), Bloomberg News (3/23, Dodge), Time (3/24, Walsh), and the New York Times (3/24, A16, Galbraith, Barringer) also report the story.

The article describes how the researchers prepared the drill site and equipment, as well as the conditions they endure working in the Arctic. The Globe notes that, "unlike many other lakes in northern latitudes," Lake El'gygytgyn "was never plowed by glaciers, which scrape away layers of soil. As a result, scientists believe, it could hold the only detailed record of sediment deposits on a polar land mass that dates back millions of years." Analyzing the samples "could tell researchers how the Arctic landscape has changed over time," among other things. (article from ASEE Mar 16, 2009)

Report: Arctic sea ice at second-lowest level

More ominous signs have some scientists saying that a global warming "tipping point" in the Arctic could be happening before their eyes: Sea ice in the Arctic Ocean is at its second-lowest level in about 30 years. The National Snow and Ice Data Center reported that sea ice in the Arctic now covers about 2.03 million square miles. The lowest point since satellite measurements began in 1979 was 1.65 million square miles set last September. With about three weeks left in the Arctic summer, this year could wind up breaking that previous record, scientists said.

Europe Turns to Coal Again, Raising Alarms on Climate

http://www.nytimes.com/2008/04/23/world/europe/23coal.html?_r=1&th=&oref=slogin&emc=th&pagewanted=all

European power companies building more coal plants.

In a front-page story, the New York Times (4/23, A1, Rosenthal) reports that "European countries are expected to put into operation about 50 coal-fired plants over the next five years," despite the fact that "the world's top climate experts agree that carbon emissions must be rapidly reduced to hold down global warming." Europe has revisited coal powered plants because of "rising demand, record high oil and natural gas prices, concerns over energy security, and an aversion to nuclear energy." But while the move alarms environmentalists, "electric companies say they have little choice but to build coal plants to replace aging infrastructure, particularly in countries like Italy and Germany that have banned the building of nuclear power plants." They also tout coal's advantages, such as large reserves and low prices. While many European power companies "emphasize that they are making the new coal plants as clean as possible," environmentalists are skeptical, and call clean coal "a pipe dream" and "building spurt shortsighted."

Greenland Ice May Not Be Headed Down Too Slippery A Slope, But Stability Still Far From Assured (April 20, 2008) -- Lubricating meltwater that makes its way from the surface down to where a glacier meets bedrock turns out to be only a minor reason why Greenland's outlet glaciers accelerated their race to the sea 50 to 100 percent in the 1990s and early 2000s, scientists say. Their work also shows that surface meltwater is reaching bedrock farther inland under the Greenland Ice Sheet, something scientists had speculated was happening but had little evidence. ... > full story

 

ASEE - U.S. must conserve gasoline, support ethanol R and D.

Wisconsin's Sheboygan Press (4/22) editorialized that the U.S. must "commit to doing two things: immediately begin to conserve gasoline by driving less and continue the research and development of alternative fuels, including ethanol." The Press pointed out that ethanol does not solely come from corn. "We're keenly aware of the rise in the price of food, blamed in part on the rush by farmers to plant corn that goes into gas and not to market or into feed." Cellulosic ethanol, "which can be produced from agricultural wastes," as well as "wood chips, sawdust,...paper pulp" and switch grass, also has potential. "The good thing about this method of producing ethanol is that none of the sources are food products," explained the Press. However, "turn[ing] cellulose into ethanol" and "doing it in a cost-efficient way is another matter." The Press concluded that the "government must do its part in providing research dollars," and should "also encourage private investment through tax breaks from capital invested in renewable energy."

Virginia Tech research team to head carbon sequestration project.

Virginia Business (4/1, Foster) reports that Dr. Michael Karmis of Virginia Tech "says that while it's an admirable goal to reduce the carbon dioxide emissions that contribute to global warming, the problem won't be fixed until those emissions are prevented from entering the atmosphere." Karmis, director of Virginia Tech's Virginia Center for Coal and Energy Research, is "heading up an $11 million-plus research project to develop technologies for carbon sequestration -- the storing of captured carbon dioxide emissions." According to Virginia Business, Karmis' "team is studying methods of injecting captured pressurized carbon dioxide gases into 'unmineable' coal seams that are too deep or thin to be commercially viable." Tests will be performed "this summer in Russell County," Va. However, "Opponents, such as the Southern Environmental Law Center, have questioned whether such technologies will ever be practical." Virginia Business notes, "Both the capture and storage technologies will likely not be available for another 10 years."

Government reports warn infrastructure planners of global warming dangers.

The New York Times http://www.nytimes.com/2008/03/12/science/12coast.html?em&ex=1205467200&en=f4fd1d869d29e1ee&ei=5087%0A (3/12, A21, Dean) reports, "A rise in sea levels and other changes fueled by global warming threaten roads, rail lines, ports, airports and other important infrastructure," according to a report by the National Research Council (NRC), "the research arm of the National Academy of Sciences." As a result, NRC researchers say "policy makers and planners should be acting now to avoid or mitigate their effects." The report found that "increased heat and 'intense precipitation events' threaten these structures," but that the greatest "potential impact is coastal flooding." Another study, this one a "multiagency effort led by the Environmental Protection Agency," added that "natural features like beaches, wetlands and fresh-water supplies are also threatened by encroaching saltwater." Henry G. Schwartz Jr., the chairman of the NRC panel and "a member of the National Academy of Engineering," said, "We need to think about it now."

        The AP (3/12, Schmid) adds that the NRC report "cites five major areas of growing threat." The first area cited in the report is "[m]ore heat waves, requiring load limits at hot-weather or high-altitude airports and causing thermal expansion of bridge joints and rail track deformities." Next, "[r]ising sea levels and storm surges flood coastal roadways," while the third area, "[m]ore rainstorms, delay[s] air and ground traffic, flooding tunnels and railways, and eroding road, bridge and pipeline supports." The fourth area of concern, "[m]ore frequent strong hurricanes," would disrupt "air and shipping service" and blow "debris onto roads [while] damaging buildings." Last, rising temperatures in the arctic would thaw "permafrost, resulting in road, railway and airport runway subsidence and potential pipeline failures." The committee noted that "proper preparation will be expensive," and it "called on federal, state and local governments to increase consideration of climate change in transportation planning and construction."

TXU answering demands

 

TXU Corp.'s suspension of plans to build eight of 11 proposed coal-fired power plants and its intention to buy more wind energy and build nuclear power plants is the right move and shows TXU is responding to concerns for the environment.

 

Wind cannot serve all our power needs because we have no way to store the energy. Wind has its own technical problems and is not entirely benign to the environment. Nuclear energy can have the lowest environmental impact if done safely. Other sources of power are either too expensive or are still in research and development.

 

If consumers were to cut back on their consumption, TXU would not need so many new plants. TXU is simply responding to customer demands for more and more electric power.

New climate report too rosy, experts say

Evidence For Human-caused Global Warming Is Now 'Unequivocal' (February 2, 2007) -- The first major global assessment of climate change science in six years has concluded that changes in the atmosphere, the oceans and glaciers and ice caps show unequivocally that the world is warming. The Intergovernmental Panel on Climate Change (IPCC) concludes that major advances in climate modelling and the collection and analysis of data now give scientists "very high confidence" (at least a 9 out of 10 chance of being correct) in their understanding of how human activities are causing the world to warm. This level of confidence is much greater than what could be achieved in 2001 when the IPCC issued its last major report.

Science Panel Says Global Warming Is 'Unequivocal'   By ELISABETH ROSENTHAL and ANDREW C. REVKIN   The report said warming and its harmful consequences could be substantially blunted by prompt action.  "Feb. 2 will be remembered as the date when uncertainty was removed as to whether humans had anything to do with climate change on this planet. The evidence is on the table."  - ACHIM STEINER, executive director of the United Nations Environment Program.

Mankind to blame for global warming says IPCC

The burning of fossil fuels and other human endeavours are causing global warming, says a major scientific report released today by the Intergovernmental Panel on Climate Change (IPCC). Written by about 600 climate experts, the UN-backed report also concluded that global warming is causing sea levels to rise and will bring drought and other extreme weather to many parts of the globe. The report, which is the IPCC's most forceful statement to date backing the scientific validity of manmade climate change, also warns that it may be too late to stop global warming by stabilizing greenhouse gas emissions.

PARIS: THE IPCC REPORT ISSUED TODAY IS ALREADY OUT OF DATE.

Even as 600 climate scientists were meeting this week to update the IPCC report on climate, the Zurich-based World Glacier Monitoring Service reported that the rate of mountain glacier melt is accelerating.  The IPCC report, however, does not incorporate data published after 2005.  The IPCC report puts the probability at 90% that human activity is responsible for the observed warming, up from 66% in 2001.  It's higher.  The report refrains from recommending what actions governments should take.

Scientists Observe Drumlin Beneath Ice Sheet

Drumlins are well known features of landscape scoured by past ice sheets and can be seen in Scotland and Northern England where they were formed during the last ice age. They form underneath the ice as it scrapes up soil and rock, and they slow down the rate at which the ice can flow.  Lead author Dr Andy Smith of BAS says, "This is the first time anyone has observed a drumlin actually forming under the ice. These results will help us interpret the way ice sheets behaved in the past, and crucially, will help predict how they might change in the future".  To the team's surprise the drumlin grew ten times faster than they had ever expected, giving a new and important insight into the drag on the underside of the ice and hence how fast ice sheets are able to flow. The study took place on the Rutford Ice Stream -- a 2-km thick, fast flowing ice stream draining part of the West Antarctic ice sheet.

* 2006 Hotter Than Ever So Far in U.S.

http://www.livescience.com/environment/060914_hot_year.html

The first eight months of 2006 was the warmest in the continental United States since record-keeping began in 1895, NOAA officials said today.

 

http://www.realclimate.org/index.php/archives/2006/03/greenland-ice-and-other-glaciers/

has interesting data and comments from readers.

 

 

http://www.sciencemag.org/cgi/content/abstract/282/5387/268 reports the Earth's heat flux in Greenland is 51.3 mW/m2.  The worldwide average is about 80 mW/m2 which includes hot spots; therefore 50 mW/m2 appears to be a reliable value.  This is the continuous heat that comes from within the earth which causes the base of the Greenland ice to be much warmer than the surface.  The surface of Greenland’s ice must be extremely cold to remove this heat and keep the ice frozen at the base of the ice.

 

http://www.ncdc.noaa.gov/paleo/icecore/greenland/summit/document/gispinfo.htm

gives –9 °C at a depth of 3000 meters and –31 °C average at the surface.  We would expect the 50 mW/m2 to be consistent with the (31–9) = 22 °C temperature difference, but it isn't.  The temperature difference is only 1/3rd of what it should be for this thickness of ice.

 

http://www.engineeringtoolbox.com/ice-thermal-properties-d_576.html gives the thermal conductivity of ice as ~2.3 W/m°C.  If the column of ice is 1 m2 and 3000 meters high with a heat flux of .05 W/m2 flowing up from the Earth, then the steady state temperature difference from bottom to top is (.05)(3000)/2.3 = 65 °C, not 22 °C in ref 2.

 

http://www.egpreston.com/icetemp.txt is a model of heat flow through 1000 meters of ice.  The program shows that only a few hundred years are needed for an average surface temperature change to propagate throughout the thick ice.  No more than ~1000 years is needed to reach steady heat flow through 3000 meters of ice.

 

http://www.secretsoftheice.org/icecore/studies.html  and

http://www.ncdc.noaa.gov/paleo/pubs/alley2000/alley2000.html  both show that the current Greenland interior surface temperature is an average of –31 °C.

 

http://www.realclimate.org/index.php?p=267 discusses ice cracks and presents a theory that melt water is running into the cracks.  This paper is suggesting that the melt water is coming from below rather than above.

 

http://news.bbc.co.uk/2/hi/science/nature/4720536.stm indicates that this process may have already begun.  Notice that I have not taken into account any global warming effect in this analysis.  The –31 °C is the average temperature of the last 10,000 years.  A warmer surface temperature will take several hundred years to propagate through the thick ice.  More likely a warmer temperature would affect the rate at which glacial ice is removed and thus allow the glaciers to reach the interior of Greenland at a much faster pace.  So how likely is the atmosphere to warm up and at what rate?

 

http://www.greenhouse.crc.org.au/crc/research/c2_bibliog.htm lists papers showing the Earth has been receiving about 10% less sunlight now than 50 years ago due mostly to air pollution and dust particles.  The papers project that the greenhouse temperature effect will become apparent when the air pollution in India and China are cleaned up.  The Nova program “Dimming of the Sun” had one researcher forecast a 17 degree F rise in global temperature in 100 years.  If true, that would certainly cause a much more rapid melting of Greenland’s glaciers.  Their research seems to be well supported with field measurements on the subject of the dimming of the sun.  It would be foolish to disregard such high quality scientific evidence.
