    You guys love to show the ice since 1979...a high point for arctic ice...go back a few years and see a steady reduction of ice...go back a lot of years and you will see that at present, there is more ice in the arctic than there has been for most of the past 10,000 years.

    Whenever someone speaking on the topic of climate shows you a short term graph, they are counting on your ignorance of the earth's climate history in order to fool you.

    How many promises of an ice free arctic must fail before you wake up to the fact that such predictions are little more than alarmist handwaving?

    This gold standard temperature reconstruction derived from ice cores taken above the arctic circle show clearly that it is colder in the arctic now, than it has been for most of the past 10,ooo years.

    Citrus is an important ag crop and is sensitive to cold. At 32 degrees F the fruit freezes and after thawing is mush inside. At 29 degrees the trunk freezes and splits open and the tree dies. In 1895 citrus was grown everywhere in N Florida and in S Ga and coastal SC. By 1960, due to colder winters, the northernmost line of commercial citrus was Macintosh, Fl. By 1980 the line was Leesburg. Today the line is Kissommee. The line of commercial citrus also represents the line of winter temps with no freezing temps.
    In 124 years this no freeze line has moved 200 miles south.
    So if global warming is real, why is Florida getting colder?

    Far to many people are politically disposed to ignore reality in favor of simply believing what people with similar political beliefs tell them to believe. You provide a fine example and yet, I hear people living in the northern part of florida going on about how hot it is now and how cold it used to be. When confronted with the very facts you just provided, they simply go away and tell someone else about hot hot it is now and how cold it used to be.

    Not too long ago the Arctic was a tropical paradise. Wooly mammoth remains frozen almost intact have been found in Alaska. And guess what DNA analysis showed? That wooly mammoths are related to elephants. Elephants are tropical climate creatures that are from India and equatorial Africa.
    So maybe only 4,000 years ago Alaska had a tropical climate. Maybe it had palm trees and monkeys and sandy beaches. And maybe Aleutian chicks were skinny and tanned and wore sarongs and did hula dances at pig roasts.
    The Earth's climate changes due to natural forces and there is nothing the prog/lib/sec/hum coalition can do to change that.

    One of the many myths of deniers.

    The captain of USS Skate wrote in his 1960 book, Surface at the Pole: The Extraordinary Voyages of the USS Skate:

    "Seldom had the ice seemed so heavy and so thick as it did in the immediate vicinity of the pole. For days we had searched in vain for a suitable opening to surface in."

    More like four million years than four thousand, but yes, the Arctic and the Antarctic were once much warmer. The latter had a rain forest where now there is ice. If AGW continues unabated, it just might be a rain forest again.

    According to the European Space Agency the Earth's magnetic field has decreased by 9% in the past 200 years.
    And, according to science, our magnetic field provides sort of a dome around the Earth to shield us from deadly UV radiation.
    So if our dome of protection has slipped in strength by 9%, could more UV radiation be the cause of global warming? Could that also be the reason cancer rates have soared?
    What sayeth thou, Billy Nie and Ricky Dawkins? Why haven't we heard all this from the esteemed scientific community? Could it be that all the college professors have joined the prog/lib/sec/ hum movement and the truth doesn't fit their world view anymore?
    There is TRUE science and there is PC science and right now it looks like PC is winning over the teuth.
