    RISING SEAS: Sea levels have risen in tandem with global warming, according to the UN's Intergovernmental Panel on Climate Change (IPCC). The global average sea level has risen since 1961 at an average rate of 1.8mm (0.07 inches) per year, but accelerated from 1991 to 3.1mm (0.12 inches) per year. The IPCC estimated sea levels would rise 18-59 centimetres (7.2-23.2 inches) by 2100. But added runoff from melting land ice is accelerating. According to Germany's Potsdam Institute for Climate Impact Research (PIK), the global sea level is likely to rise at least twice as much as projected. If emissions are not curbed, "it may well exceed one metre (3.25 feet)."

    SHRINKING GLACIERS: Mountain glaciers and snow cover in both hemispheres have widely retreated in the past few decades. One of the most closely-observed sites, the Cook glacier on the southern Indian Ocean island of Kerguelen, has shrunk by a fifth in 40 years. Around 1.3 billion people depend on the water that flows down from Himalayan glaciers, which in some places are falling back at up to 70 metres (230 feet) per year. The snows capping Mount Kilimanjaro, Africa's tallest peak, could vanish entirely in 20 years, US experts reported this month.

    SHIFTING SEASONS: Some species of birds and fish are shifting habitat in response to warmer temperatures. The range of 105 bird species in France moved north, on average, 91 kilometres (56.5 miles) from 1989 to 2006. Average temperatures, however, shifted northward 273 kilometres (170 miles) over the same period, nearly three times farther. Twenty-one out of 36 species of fish in the North Sea migrated northwards between 1962 and 2001 in search of cooler waters. Anecdotal evidence from commercial fishermen says once-exotic species of fish from warmer latitudes now inhabit southern British waters.

    OCEAN ACIDIFICATION: The acidity of the seas is rising as oceans absorb more carbon dioxide (CO2), with an impact on coral and micro-organisms, marine biologists say. Since the start of the Industrial Revolution, the protective calcium shell of amoeba-like organisms living in the Southern Ocean called foraminifera, a vital link in the food chain, has fallen in weight by a third. "Within decades," acidification could severely affect biodiversity and fisheries, 150 marine scientists jointly warned last January.

    ARCTIC ICE: The Greenland ice sheet has lost 1,500 billion tonnes of ice since 2000, contributing 0.75 mm (0.03 inch) annually to sea levels, according to a study published this month. In 2009, the Arctic summer sea ice pack thawed to its third smallest size on record, confirming a shrinkage trend seen over the past 30 years. Some experts believe the Arctic ice cap will disappear completely in summer months within 20 to 30 years.

    ANTARCTIC WARMING: The Antarctic peninsula has warmed by 2.5 degrees Celsius (4.5 degrees Fahrenheit) in the last 50 years, around six times the global average. In the past 20 years, Antarctica has lost seven ice shelves -- huge floating ledges of ice, attached to the shore, that are fed by glaciers.

    PERMAFROST RETREAT: Emissions of the potent greenhouse gas methane were found to be soaring at sites investigated in 2006 by University of Alaska scientists at lakes in northern Siberia. The reason is thawing of the permafrost, causing the warmed soil to release gas that had been stored for thousands of years. Billions of tonnes of methane, which comes from natural sources such as decomposing vegetation and marshland, are stored in the frozen lands of Siberia, Canada and Alaska.

    Seems it also has the effect of making scientists want to fake evidence, browbeat publications that give equal time to opposing POV, destroy contrary evidence and evade FOIA laws.

    The ice caps are melting, the glaciers are melting, and the temperatures are rising.

    That is the evidence.

    And the winters here in Virginia are radically different than they were 25 years ago. I remember a Super Bowl Sunday when it was 0 degrees. We never see weather like that anymore.

    You are an absolute liar - just like most the global warmers apparently...


    Lynchburg breaks 84-year cold record
    March 7, 2009





    By Dave Thompson Lynchburg News & Advance


    roanoke,va – Lynchburg broke an 84-year record Tuesday morning, posting the first single-digit temperature for that date since records have been kept.[/B] The low came in at 5 degrees, according to the National Weather Service in Blacksburg. The previous mark was 11 degrees, set in 1925. The frigid temperatures followed a heavy snowfall that blanketed Central Virginia overnight Sunday and into Monday. Lynchburg saw 10 inches of snow and some areas in the region saw up to 14 inches. The storm’s worst may be over, but the cold temperatures and possibility of icy conditions kept residents on their toes through Tuesday and into today, when this morning’s low temperature was expected to hit 7 degrees.Public schools in the counties of Appomattox, Bedford and Campbell all announced cancellations for today, and Nelson County will work on a 1-hour delay, due to a chance of icy roads. Lynchburg City Schools officials said last night they expected school to be open today. A slew of outages in Appomattox County was trimmed down. Central Virginia Electric Cooperative reported 232 outages with another 19 listed from a combined substation covering both Appomattox and Buckingham counties, as of 10 p.m. Tuesday. Greg Kelly, spokesperson for CVEC, said he didn’t know when power would be restored to all the customers, and stopped short of predicting full recovery by midnight Tuesday. Doug Eggleston, emergency services coordinator with the Historic Virginia Chapter of the American Red Cross, said demand for Red Cross assistance has been low. An emergency shelter established in Appomattox County due to the widespread outages was closed shortly after opening on Monday because, Eggleston said, only one family showed up. That family and another Appomattox County family that contacted the Red Cross were relocated to other homes. Relief from the cold and wintry weather is on its way.According to the National Weather Service’s forecast Tuesday night, temperature today should reach the lower 40s before dipping into the mid 20s tonight. Thursday is forecast to get even warmer, with highs in the mid-50s and lows near 40 degrees

    Furthermore...


    The average mean temp for December 15 - March 3, 2008 - 2009 in Richmond Virginia was 40 degrees.

    Go back 25 years when you say Virginia used to have cold winters. The average mean temp for December 15 - March 3 in 1984-1985 was...40 degrees.

    Go back 35 years - the average temperature was...41 degrees.

    Go back 45 years - the average temperature was...40 degrees.

    Go back 55 years - the average temperatures was...41 degrees.

    Check out the historical data on weather underground pard.

    Chris, you are either a complete moron, or an outright liar - maybe both.

    Either way, you are unworthy to speak on this topic any longer...

    No, you are the moron.

    I live in Va. Beach, not Lynchburg!

    And it was 1987 or 86 somewhere in there, so it was probably more like 22 years.

    And we never have snow or winters like we used to here.

    It hasn't come close to 0 degrees here in a long while.

    Anyone else smell the rancid flop-sweat stench of the panicked environazis out there trying desperately to save their empire of lies?

    How many threads tonight that make for you on this topic, Chris? 6?

    It was January 20, 1985, so it will be 25 years in January....

    January 20-22, 1985: An arctic cold front swept across the state ushering in extreme cold and high winds. Wind chill temperatures plunged well below zero. Winds knocked out power compounding the effects of the cold. Pipes froze and burst. Fresh snow of 4 inches with the front helped temperatures across the entire state fall below zero. New records were set at several locations in the south including Roanoke with -11°F and Norfolk with -3°F. Cable television lines were damaged by shrinkage caused by the extreme cold. On January 22, Mountain Lake recorded the coldest temperature ever in the state with -30°F.

    When people post insults, it's because they have no facts.

    Thanks for admitting defeat, eots.

    You're the best!
