    WASHINGTON (AP)  The global output of heat-trapping carbon dioxide jumped by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world's efforts are at slowing man-made global warming.

    The new figures for 2010 mean that levels of greenhouse gases are higher than the worst case scenario outlined by climate experts just four years ago.

    "The more we talk about the need to control emissions, the more they are growing," said John Reilly, co-director of MIT's Joint Program on the Science and Policy of Global Change.

    The world pumped about 564 million more tons (512 million metric tons) of carbon into the air in 2010 than it did in 2009. That's an increase of 6 percent. That amount of extra pollution eclipses the individual emissions of all but three countries  China, the United States and India, the world's top producers of greenhouse gases.

    It is a "monster" increase that is unheard of, said Gregg Marland, a professor of geology at Appalachian State University, who has helped calculate Department of Energy figures in the past.

    Extra pollution in China and the U.S. account for more than half the increase in emissions last year, Marland said.

    "It's a big jump," said Tom Boden, director of the Energy Department's Carbon Dioxide Information Analysis Center at Oak Ridge National Lab. "From an emissions standpoint, the global financial crisis seems to be over."

    Boden said that in 2010 people were traveling, and manufacturing was back up worldwide, spurring the use of fossil fuels, the chief contributor of man-made climate change.

    India and China are huge users of coal. Burning coal is the biggest carbon source worldwide and emissions from that jumped nearly 8 percent in 2010.

    "The good news is that these economies are growing rapidly so everyone ought to be for that, right?" Reilly said Thursday. "Broader economic improvements in poor countries has been bringing living improvements to people. Doing it with increasing reliance on coal is imperiling the world."

    In 2007, when the Intergovernmental Panel on Climate Change issued its last large report on global warming, it used different scenarios for carbon dioxide pollution and said the rate of warming would be based on the rate of pollution. Boden said the latest figures put global emissions higher than the worst case projections from the climate panel. Those forecast global temperatures rising between 4 and 11 degrees Fahrenheit by the end of the century with the best estimate at 7.5 degrees.

    Even though global warming skeptics have attacked the climate change panel as being too alarmist, scientists have generally found their predictions too conservative, Reilly said. He said his university worked on emissions scenarios, their likelihood, and what would happen. The IPCC's worst case scenario was only about in the middle of what MIT calculated are likely scenarios.

    Chris Field of Stanford University, head of one of the IPCC's working groups, said the panel's emissions scenarios are intended to be more accurate in the long term and are less so in earlier years. He said the question now among scientists is whether the future is the panel's worst case scenario "or something more extreme."

    "Really dismaying," Granger Morgan, head of the engineering and public policy department at Carnegie Mellon University, said of the new figures. "We are building up a horrible legacy for our children and grandchildren."

    But Reilly and University of Victoria climate scientist Andrew Weaver found something good in recent emissions figures. The developed countries that ratified the 1997 Kyoto Protocol greenhouse gas limiting treaty have reduced their emissions overall since then and have achieved their goals of cutting emissions to about 8 percent below 1990 levels. The U.S. did not ratify the agreement.

    In 1990, developed countries produced about 60 percent of the world's greenhouse gases, now it's probably less than 50 percent, Reilly said.

    "We really need to get the developing world because if we don't, the problem is going to be running away from us," Weaver said. "And the problem is pretty close from running away from us."

    We've only got about 13 months left anyway.

    A huge, emerging crack has been discovered in one of Antarctica's glaciers, with a NASA plane mission providing the first-ever detailed airborne measurements of a major iceberg breakup in progress.

    NASA's Operation Ice Bridge, the largest airborne survey of Earth's polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. The glaciers of the Antarctic, and Greenland, Ice Sheets, commonly birth icebergs that break off from the main ice streams where they flow in to the sea, a process called calving.

    The crack was found in Pine Island Glacier, which last calved a significant iceberg in 2001; some scientists have speculated recently that it was primed to calve again. But until an Oct. 14 IceBridge flight, no one had seen any evidence of the ice shelf beginning to break apart. Since then, a more detailed look back at satellite imagery seems to show the first signs of the crack in early October.

    "We are actually now witnessing how it happens and it's very exciting for us," said IceBridge project scientist Michael Studinger of NASA's Goddard Space Flight Center in Greenbelt, Md. "It's part of a natural process, but it's pretty exciting to be here and actually observe it while it happens."

    Gravity pulls the ice in the glacier westward along Antarctica's Hudson Mountains toward the Amundsen Sea. A floating tongue of ice reaches out 30 miles (48 kilometers) into the Amundsen beyond the grounding line, the below-sea-level point where the ice shelf locks onto the continental bedrock. As ice pushes toward the sea from the interior, inevitably the ice shelf will crack and send a large iceberg free.

    Pine Island Glacier is of particular interest to scientists because it is big and unstable and so is one of the largest sources of uncertainty in global sea level rise projections.

    A primary goal of Operation IceBridge is to put the same instruments over the exact same flight lines and satellite tracks, year after year, to gather meaningful and accurate data of how ice sheets and glaciers are changing over time. But discovering a developing rift in one of the most significant science targets in the world of glaciology offered a brief change in agenda for the Oct. 26 flight, if only for a 30-minute diversion from the day's prescribed flight lines.

    The IceBridge team observed the rift running across the ice shelf for about 18 miles (29 km), using an instrument called the Airborne Topographic Mapper, which uses a technology called lidar (light detection and ranging) that sends out a laser beam that bounces off a surface and back to the device. The lidar instrument measured the rift's shoulders about 820 feet (250 meters) apart at its widest, although the rift stretched about 260 feet (79 meters) wide along most of the crack. The deepest points from the ice shelf surface ranged from 165 to 195 feet (50 to 60 meters).

    When the iceberg breaks free, it will cover about 340 square miles (880 square kilometers) of surface area. Radar measurements suggested the ice shelf in the region of the rift is about 1,640 feet (500 meters) feet thick, with only about 160 feet of the shelf floating above water and the rest submerged.

    It is likely that once the iceberg floats away, the leading edge of the ice shelf will have receded farther than at any time since its location was first recorded in the 1940s.

    I just cranked the heat up to 74......and cracked open a window for some fresh air...:coffee:

    Gore made 100 million on the man-made Global warming fraud and fucked Larry Davids wife.....who then took 1/2 of Larrys money.

    Between this and the moon slipping further away we're just completely fucked, right Bro?




    Bro is to planetary doom what LHJ is to economic gloom. :c

    The theory that solar activity has something to do with the slight warming and cooling of the earth that is taking place today considered a controversial theory.
    That's how far down Gore has dumbed down the debate.

    Why does this always turn into an Al Gore thing? These are scientists making these conclusions...al gore was just a messenger. al gore isn't even mentioned in the article. :facepalm:

    The Stop Global Warming College Tour....had these idiots making the rounds on TV telling us that earth would be a boiling cauldron in 5-10 years.
    That was 5 years ago.

    Ever park with a girl? It is a lot easier to get some action if the moon is out.

    When I see commercials for coal it makes my skin crawl. That's right, commercials for coal.
