An instant ice age

Puts man made global warming and industrial pollution into perspective, doesn't it? We can't hold a candle to natural disasters. From the University of Illinois LAS News:
    "A new study provides “incontrovertible evidence” that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report.

    The volcano ejected an estimated 800 cubic kilometers of ash into the atmosphere, leaving a crater (now the world’s largest volcanic lake) that is 100 kilometers long and 35 kilometers wide. Ash from the event has been found in India, the Indian Ocean, the Bay of Bengal, and the South China Sea.

    The bright ash reflected sunlight off the landscape, and volcanic sulfur aerosols impeded solar radiation for six years, initiating an “Instant Ice Age” that—according to evidence in ice cores taken in Greenland—lasted about 1,800 years.

    During this instant ice age, temperatures dropped by as much as 16 degrees centigrade (28 degrees Fahrenheit), says University of Illinois anthropology professor Stanley Ambrose, a principal investigator on the new study with professor Martin A.J. Williams, of the University of Adelaide. Williams, who discovered a layer of Toba ash in central India in 1980, led the research."
Did you know that the warming cooling cycle research on the earth's temperature had been gradually removed from Wikipedia by global warming fundamentalists?
