  • AP IMPACT: Statisticians reject global cooling By SETH BORENSTEIN, AP Science Writer — Mon Oct 26, 9:34 pm ET

    WASHINGTON — Have you heard that the world is now cooling instead of warming? You may have seen some news reports on the Internet or heard about it from a provocative new book. Only one problem: It´s not true, according to an analysis of the numbers done by several independent statisticians for The Associated Press.

    The case that the Earth might be cooling partly stems from recent weather. Last year was cooler than previous years. It´s been a while since the super—hot years of 1998 and 2005. So is this a longer climate trend or just weather´s normal ups and downs?..(more)

    SWEDEN is to become the first country to slap "climate—friendly" labels on food products. The hope is that the labels will prompt consumers to buy greener products, but there are worries that some companies may use the scheme to "greenwash".

    A small milk producer north of Stockholm is expected to be the first company to sport the "climate-certified" tag. One way it cut its use of energy and nutrients was by switching from chemical-based fertilisers to manure...(more)

    Three events scheduled in Durango on Friday and Saturday are among 3,000 grass—roots rallies in 160 countries this weekend to call attention to global warming.

    International participation in the Day of Climate Action has been promoted by the loosely organized 350.org — a group that takes its name from the recommended maximum of 350 parts per million of carbon dioxide in the atmosphere. The organization, which claims the support of scientists, the governments of 89 countries and environmental and health-care groups, is a clearinghouse and information center.

    The current level of carbon dioxide in the atmosphere is 390 ppm.

    "350.org just put the idea out there and invited others to follow," said Claire Ninde, who volunteered to coordinate publicity for the Durango events...(more)

    Coincidentally, the crowd appeared to number about 350 Saturday as Boulder joined 4500 locations worldwide rallying in a "Climate Day of Action" organized by 350.org. The event included a bikeride by about 200 partipants to the Valmont Power Plant on Arapahoe Ave. calling for an end to coal-burning at the facility, which can also burn natural gas.

    Then, downtown, speakers, including Rep. Jared Polis, called for strong action to resist further global climate change. ..(more)

    Thousands of similar events will be held in 170 countries worldwide in a bid to reduce the amount of carbon in the atmosphere to a level of 350 parts per million...(more)

  • Campaign Against Emissions Picks Number

    Published: October 24, 2009

    Campaigners against global warming have drawn on an arsenal of visually startling tactics over the years, from posing nude on a Swiss glacier to scaling smokestacks at coal—fired power plants.

    On Saturday, they tried something new with the goal of prodding countries to get serious about reaching an international climate accord: a synchronized burst of more than 4,300 demonstrations, from the Himalayas to the Great Barrier Reef, all centered on the number 350.

    For some prominent climate scientists, that is the upper limit for heat—trapping carbon dioxide in the atmosphere, measured in parts per million. If the gas concentration exceeds that for long, they warn, the world can expect decades of disrupted climate patterns, rising sea levels, drought and famine. The current concentration is 387 parts per million...(more)

  • Global warming to triple rain over Taiwan: scientist Tue Oct 13, 5:35 am ET

    TAIPEI (AFP) — Global warming will cause the amount of heavy rain dumped on Taiwan to triple over the next 20 years, facing the government with the urgent need to beef up flood defences, a scientist warned Tuesday.

    The projection is based on data showing the incidence of heavy rain has doubled in the past 45 years, coinciding with a global rise in temperatures, said Liu Shaw—chen of Taiwan's leading research institute Academia Sinica...(more)

    HONG KONG, China (CNN) -- The last fifty years have borne witness to a spate of climate related disasters across the world causing over 800,000 fatalities and $1 trillion in economic loss.

    Those stark facts come from the Economics of Climate Adaptation (ECA) Working Group, a group of NGOs and corporations that has produced a report warning that if countries do not take active steps to build resilience to climate change soon, they are likely to suffer even larger economic losses in the coming decades.

    According to the ECA report published on September 14, climate catastrophes have risen in direct proportion to global temperatures over the last several years. ..(more)

  • US says climate bill might not pass in time By MICHAEL CASEY
    The Associated Press
    Sunday, September 27, 2009; 10:03 AM

    BANGKOK — The passage of a U.S. bill capping carbon emissions before a major U.N. climate conference in December would help the United States extract concessions from other countries, though time is running out, the chief U.S. negotiator at climate talks in Bangkok said Sunday.

    "The more specific we can be, the easier it is to press others to be equally specific," Jonathan Pershing told The Associated Press. "We have a lot of things we want from countries. We want significant action from other developed and developing countries ... The less we can put on the table, the harder it is to achieve that outcome." ...(more)

  • Investors Worth $13 Trillion Urge Strong Global Climate Treaty

    NEW YORK, New York, September 16, 2009 (ENS) — The world's largest global investors today issued a joint call for strong action this year from U.S. and international policy makers to control global warming. Signed by 181 investors, who collectively manage more than $13 trillion in assets worldwide, the statement on the "urgent need for global agreement on climate change" was released at the International Investor Forum on Climate Change in New York.

    Hosted by New York State Comptroller Thomas DiNapoli and keynoted by British economist Lord Nicholas Stern, the forum comes in advance of key negotiations in Copenhagen this December to finalize a new international climate change treaty to take effect after the Kyoto Protocol expires at the end of 2012.

    "Unmitigated climate change poses a threat to the global economy," said Stern. "But building a low carbon economy creates opportunities for investment in new technologies that promise to transform our society in the same way as the introduction of electricity or railways did in the past."...(more)

  • Scientists find CO2 link to Antarctic ice cap origin By David Fogarty, Climate Change Correspondent, Asia — Sept 14, 2009

    SINGAPORE (Reuters) — A team of scientists studying rock samples in Africa has shown a strong link between falling carbon dioxide levels and the formation of Antarctic ice sheets 34 million years ago.

    The results are the first to make the link, underpinning computer climate models that predict both the creation of ice sheets when CO2 levels fall and the melting of ice caps when CO2 levels rise...(more)

  • EPA holds up 79 permits for Appalachian surface mines By Renee Schoof, McClatchy Newspapers — Fri Sep 11, 6:54 pm ET

    WASHINGTON &mdssh; The Environmental Protection Agency announced Friday that 79 applications for surface coal-mine permits in Kentucky , West Virginia , Ohio and Tennessee might violate the nation's Clean Water Act and require closer scrutiny.

    Many of the 79 applications would remove mountaintops and dump debris in valley streams.

    The EPA´s action was an abrupt shift from the last big batch of surface mining permits that it's considered during the Obama administration. In May, the agency said it had no concerns with 42 of 48 permits, and blocked six...(more)

  • Arctic Thaw Could Cause Massive Flood, Curbing Non-CO2 Pollutants Could Help

    GENEVA, Switzerland, September 4, 2009 (ENS) — Continued warming of the Arctic could lead to global weather changes and flooding that affects one-quarter of the world's people, finds a new report by the global conservation organization WWF.

    The report was released in Geneva at the World Climate Conference-3, hosted by the World Meteorological Organization. Some 2,000 delegates are meeting to lay the groundwork for a global system of climate change forecasting.

    Arctic air temperatures have risen by almost twice the global average over the past several decades, according to the peer-reviewed scientific report, which warns that further warming could release more greenhouse gases now trapped in the Arctic's frozen soil.

    "What this report says is that a warming Arctic is much more than a local problem, it's a global problem," said Martin Sommerkorn, senior climate change advisor with the WWF's Arctic Programme. "Simply put, if we do not keep the Arctic cold enough, people across the world will suffer the effects." ..(more)

  • In tiny `Tuk,' they man climate's front line

    By CHARLES J. HANLEY, AP Special Correspondent Charles J. Hanley, Ap Special Correspondent — Mon Sep 7, 4:53 pm ET

    TUKTOYAKTUK, Northwest Territories — Caught between rising seas and land melting beneath their mukluk-shod feet, the villagers of Tuktoyaktuk are doing what anyone would do on this windy Arctic coastline. They're building windmills.

    That's wind-power turbines, to be exact — a token first try at "getting rid of this fossil fuel we're using," said Mayor Merven Gruben.

    It's a token of irony, too: People little to blame, but feeling it most, are doing more to stop global warming than many of "you people in the south," as Gruben calls the rest of us who fill the skies with greenhouse gases...(more)

  • Warmest Arctic temperatures for 2,000 years, says new study updated 11:59 p.m. EDT, Thu September 3, 2009

    (CNN) — Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years, new research indicates.

    The study presents new evidence that the Arctic would be cooling if not for greenhouse gas emissions overpowering natural climate patterns.

    The report published in Science magazine found that thousands of years of gradual Arctic cooling, related to natural changes in Earth´s orbit, would continue today if not for emissions of carbon dioxide and other greenhouse gases.

    "This result is particularly important because the Arctic, perhaps more than any other region on Earth, is facing dramatic impacts from climate change," NCAR scientist David Schneider, one of the co—authors, said in a statement.

    (AP) On continent's boggy Arctic fringe, scientists search for signs of future climate calamity
    By CHARLES J. HANLEY AP Special Correspondent
    MACKENZIE RIVER DELTA, Northwest Territories August 30, 2009 (AP)

    Only a squawk from a sandhill crane broke the Arctic silence — and a low gurgle of bubbles, a watery whisper of trouble repeated in countless spots around the polar world.

    "On a calm day, you can see 20 or more ´seeps´ out across this lake," said Canadian researcher Rob Bowen, sidling his small rubber boat up beside one of them. A tossed match would have set it ablaze.

    "It´s essentially pure methane."

    Pure methane, gas bubbling up from underwater vents, escaping into northern skies, adds to the global—warming gases accumulating in the atmosphere. And pure methane escaping in the massive amounts known to be locked in the Arctic permafrost and seabed would spell a climate catastrophe.


  • New study shows nitrous oxide now top ozone-depleting emission August 27th, 2009

    Nitrous oxide has now become the largest ozone—depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study.

    For the first time, this study has evaluated nitrous oxide emissions from human activities in terms of their potential impact on Earth's ozone layer. As chlorofluorocarbons (CFCs), which have been phased out by international agreement, ebb in the atmosphere, nitrous oxide will remain a significant ozone—destroyer, the study found. Today, nitrous oxide emissions from human activities are more than twice as high as the next leading ozone-—depleting gas...(more)

  • Scientists Detect Greenhouse Gas Buildup Over Alaska

    KODIAK ISLAND, Alaska, August 24, 2009 (ENS) — Billions of tons of carbon are buried in the frozen Arctic tundra, now heating up because of human—caused climate change. To measure which greenhouse gases are being released and in what quantities, government scientists are flying instrument—laden planes over the tundra from now through November.

    They say recent observations indicate that the air above Alaska "may already hold the first signs of a regional increase in greenhouse gas emissions" that could contribute to global climate change...more

  • Beetles, wildfire: Double threat in warming world By CHARLES J. HANLEY (AP)

    HAINES JUNCTION, Yukon Territory — A veil of smoke settled over the forest in the shadow of the St. Elias Mountains, in a wilderness whose spruce trees stood tall and gray, a deathly gray even in the greenest heart of a Yukon summer.

    "As far as the eye can see, it´s all infested," forester Rob Legare said, looking out over the thick woods of the Alsek River valley.

    Beetles and fire, twin plagues, are consuming northern forests in what scientists say is a preview of the future, in a century growing warmer, as the land grows drier, trees grow weaker and pests, abetted by milder winters, grow stronger...(more)

  • Texas drought losses could be worst ever By Betsy Blaney, Asociated Press LUBBOCK, Texas — Drought in Texas has led to an estimated $3.6 billion in crop and livestock losses, and without ample rains, the year´s final tally could top the state record set in 2006, Texas agriculture officials say.

    Crops and rangeland are scorched from lack of rainfall and record triple-digit temperatures throughout parts of Texas — the nation's second—largest agriculture state behind California. Much of the central and southern parts of the state have been in the two most severe stages of drought for months.

  • G8 leaders ´ignored´ UN´s scientific findings on climate change, says official 20 July 2009 — The world´’s largest economies have "clearly ignored" the findings of the Nobel Peace Prize-winning United Nations scientific body that evaluates climate change when formulating their recent proposals on slashing greenhouse gases, a top official said today.

    It was a "big step" for leaders of over one dozen developed nations attending the Major Economies Forum (MEF) — including the Group of Eight (G8) nations and others — on 9 July meeting in L´Aquila, Italy, to recognize that the global average temperature should not increase by more than 2 degrees centigrade, Rajendra Pachauri, Chair of the UN Intergovernmental Panel on Climate Change (IPCC), told reporters in New York today.

    (posted here July 17)

    ...The woman shivered in her worn, blue down jacket and glanced up at the overcast sky. After one more cautious step, she spotted her quarry: a cluster of platter-size bubbles frozen into the ice. Those pockets of gas, which had risen from thawing permafrost—formerly frozen soil—at the lake´s bottom, were the aim of her doctoral research. Long elusive, they suddenly stood out like white stars against a night sky, though less serenely. With a small pick she cracked the icy skin of one of the bubbles and remained unfazed when it hissed back like a punctured gas pipe. Leaning forward, she apprehensively struck a match just above the broken bubble and flames as high as her head burst skyward. The flammable substance was methane, a greenhouse gas that could cause more global warming than carbon dioxide (CO2)...(more)

    Recent warming in the Southwest has been among the most rapid in the nation. This is driving declines in spring snowpack and Colorado River flow. Projections of future climate change indicate continued strong warming in the region, with much larger increases under higher emissions scenarios compared to lower. Projected summertime temperature increases are greater than the annual average increases in parts of the region and are likely to be exacerbated by expanding urban heat island effects. Further water cycle changes are projected, which combined with increasing temperatures signal a serious water supply challenge in the decades and centuries ahead. The prospect of future droughts becoming more severe due to warming is a significant concern, especially because the Southwest continues to lead the nation in population growth...(more)

    Libby, age 6, and the 74 other dairy cows on Guy Choiniere’s farm here are at the heart of an experiment to determine whether a change in diet will help them belch less methane, a potent heat-trapping gas that has been linked to climate change. ..(more)

  • Air Quality in the Four Corners and San Juan Mountains - Mountain Studies Institute Overview:

    MSI is addressing pressing air quality issues concerns with a combination of research, monitoring, outreach, and collaboration.

    The San Juan Mountains are perceived as having crystal clean air due to the remoteness from large cities. These mountains are in close proximity to an industrialized area, however. The Four Corners is a center for coal-fired energy and methane (natural gas) production. For example, San Juan County in northwestern New Mexico is one of the largest emitters of power plant mercury among all counties in the nation. An additional coal-fired power plant and about 12,000 more natural gas wells are proposed for the Four Corners. ..(more)

  • New worries on Arctic permafrost thaw By Alister Doyle, Environment Correspondent – Fri May 22, 8:49 am ET

    OSLO (Reuters) – A rise in concentrations of a powerful greenhouse gas over the Arctic after a decade of stability is stirring worries about a possible thaw of vast stores trapped in permafrost, experts said.

    Levels of methane in the atmosphere rose 0.6 percent in 2008, according to preliminary data from the Zeppelin station on a remote island in the Norwegian Arctic, after a similar 0.6 percent gain in 2007, Norwegian officials said.

    The 2007 rise outpaced a global rise in methane of 0.34 percent to a new record high after levels had been stable for about a decade. World data for 2008 are not yet available...(more)

    JUNEAU, Alaska — Global warming conjures images of rising seas that threaten coastal areas. But in Juneau, as almost nowhere else in the world, climate change is having the opposite effect: As the glaciers here melt, the land is rising, causing the sea to retreat.

    Morgan DeBoer, a property owner, opened a nine-hole golf course at the mouth of Glacier Bay in 1998, on land that was underwater when his family first settled here 50 years ago. Mr. DeBoer figures he has picked up enough additional land since then to build nine more holes...(more)

  • Federal Government Cracks Down on Mercury Pollution From Cement Kilns Air pollution rules from new administration will cut mercury pollution by between 81 and 93 percent
    April 21, 2009

    Washington, DC -- The federal government is proposing, for the first time, to reduce airborne mercury pollution from cement kilns with new rules issued today. The new standards will cut mercury pollution from the nation's more than 150 cement kilns between 11,600 and 16,250 pounds (or a reduction of 81 to 93 percent), according to the US Environmental Protection Agency.

    Led by Lisa Jackson, the EPA Administrator newly appointed by President Obama, EPA is proposing first time standards for cement kilns of mercury, hydrochloric acid, and toxic organic pollutants such as benzene. In addition, the agency is strengthening the outdated standards for particulate matter to better control kilns' emissions of lead, arsenic, and other toxic metals...(more)

  • Antarctic drilling yields global warming insights By William Mullen ¦ Tribune reporter
    1:46 PM CDT, March 18, 2009

    ...In a report published on the cover of the research journal Nature, the researchers found that during the Pliocene epoch 3 to 5 million years ago--a time when conditions in Antarctica are similar to today's--the ice in Antarctica collapsed and melted on a regular basis, raising world sea levels.

    Polar ice began melting on a massive scale when atmospheric carbon dioxide levels were up to around 400 parts per million in the Pliocene, said Northern Illinois University geologist Ross Powell, one of the chief ANDRILL scientists. "Today and we are now at 386 parts per million and rising," he said, and it grows by one part per million every year, thanks to carbon dioxide that human activity is putting into the atmosphere...(more)

  • Global warming danger threat increased By RANDOLPH E. SCHMID, AP Science Writer – Mon Feb 23, 5:05 pm ET

    WASHINGTON – The Earth won't have to warm up as much as had been thought to cause serious consequences of global warming, including more extreme weather and increasing threats to plants and animals, says an international team of climate experts.

    The Intergovernmental Panel on Climate Change estimated that the risk of increased severe weather would rise with a global average temperature increase of between 1.8 degrees Fahrenheit and 3.6 degrees above 1990 levels. The National Climatic Data Center currently reports that global temperatures have risen 0.22 degree since 1990.

    Now, researchers report that "increases in drought, heat waves and floods are projected in many regions and would have adverse impacts, including increased water stress, wildfire frequency and flood risks starting at less than (1.8 degrees) of additional warming above 1990 levels."..(more)

Scientists at the annual meeting of the American Association for the Advancement of Science on Feb. 14 reported that worldwide CO2 emission rates had risen more precipitously between 2000 and 2008 than the IPCC's worst-case scenario, thanks largely to an unexpected increase in coal-burning in developing countries like China. ..(more)

  • Will Climate Go Over The Edge? Even a miracle of diplomacy wouldn't put global warming back in its box.
    By Fred Guterl | NEWSWEEK
    Published Feb 21, 2009
    From the magazine issue dated Mar 2, 2009

    There is something compelling, in a ghoulish sort of way, about the notion that earth's climate may be headed toward a tipping point. The idea gained broad currency in 2007, when a panel of scientists, including Harvard environmental expert John Holdren—now the White House science adviser—warned that the planet is approaching a threshold beyond which damage to the environment would be irreversible. As policymakers work toward a climate treaty in Copenhagen in December that will include new limits on emissions, the question in the back of everyone's mind is whether an agreement can halt the warming trend, or at least stave off the worst consequences. Or is it already too late? A definitive answer isn't forthcoming, but the signs in recent months have been gloomy...(more)

  • Scientists say a rock can soak up carbon dioxide By Timothy Gardner – Fri Nov 7, 10:36 am ET
    NEW YORK (Reuters) – A rock found mostly in Oman can be harnessed to soak up the main greenhouse gas carbon dioxide at a rate that could help slow global warming, scientists say.

    When carbon dioxide comes in contact with the rock, peridotite, the gas is converted into solid minerals such as calcite.

    Geologist Peter Kelemen and geochemist Juerg Matter said the naturally occurring process can be supercharged 1 million times to grow underground minerals that can permanently store 2 billion or more of the 30 billion tons of carbon dioxide emitted by human activity every year.

    Their study will appear in the November 11 edition of the Proceedings of the Natural Academy of Sciences....(more)

    LONDON, England (CNN) -- A team of international scientists led by Dr James Hansen, director of NASA's Goddard Institute for Space Studies, say that carbon dioxide (CO2) levels are already in the danger zone.

    Concentrations of CO2 in the atmosphere currently stand at 385 parts per million (ppm) and are rising at a rate of two ppm per year. This is enough, say the scientists, to encourage dangerous changes to the Earth's climate.

    As a result we risk expanding desertification, food shortages, increased storm intensities, loss of coral reefs and the disappearance of mountain glaciers that supply water to hundreds of millions of people.

    ...It is a departure from the previous climate estimates which predict that perilous CO2 levels will be reached later in the century....(more)
