    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.
