    Notwithstanding corporate efforts to try to make it seem that there is actual controversy on the subject of global warming... :

    Explain to me why the meteorologists will probably get tomorrow's temps wrong, by more than 1 degree. Not to mention precip or lack thereof...

    Let's just start there, with science.

    You mean the polar ice caps are melting by themselves? :scratch:

    In some cases big chunks are being removed. They're in the way and all.

    These are melting too.

    I'm sad. Especially when they are in a drink.

    Ruins the taste.

    :(

    Thank you. Interesting site.

    From your link:

    Over the past three centuries, the concentration of carbon dioxide has been increasing in the Earth's atmosphere because of human influences (Figure 7y-3). Human activities like the burning of fossil fuels, conversion of natural prairie to farmland, and deforestation have caused the release of carbon dioxide into the atmosphere. From the early 1700s, carbon dioxide has increased from 280 parts per million to 360 parts per million in 1990. Many scientists believe that higher concentrations of carbon dioxide in the atmosphere will enhance the greenhouse effect making the planet warmer. Scientists believe we are already experiencing global warming due to an enhancement of the greenhouse effect. Most computer climate models suggest that the globe will warm up by 1.5 - 4.5° Celsius if carbon dioxide reaches the predicted level of 600 parts per million by the year 2050.

    *graph* (sorry I can't get it copied)


    Figure 7y-3: The following graph illustrates the rise in atmospheric carbon dioxide from 1744 to 1992. Note that the increase in carbon dioxide's concentration in the atmosphere has been exponential during the period examined. An extrapolation into the immediate future would suggest continued increases.
