Aha! Al Gore and his pals haven’t produced research ruling out leprechauns as cause of global warming!


Roy Spencer, a climate scientist who is skeptical of mainstream theories regarding man-made global warming, demands to see even “one peer-reviewed paper that has ruled out natural, internal climate cycles as the cause of most of the recent warming in the thermometer record.”

THIS RESPONSE to Spencer’s challenge makes a good case.

An excerpt:

This challenge is problematic for a few reasons.  Firstly, the fact that research has not ruled out a hypothesis does not mean the hypothesis necessarily has any validity.  For example, there have been no peer-reviewed papers ruling out leprehchauns as the cause of most of the recent global warming, either.  But perhaps more importantly, our understanding that humans are causing global warming is not based on just one scientific study, but rather a very wide range of scientific evidence.

For example, scientists have measured the amount of heat being re-directed back towards the Earth’s surface due to the increased greenhouse effect.  Quantifying the amount of global warming that this will cause simply involves multiplying the increased downward energy by the climate sensitivity.  As the name suggests, climate sensitivity is a measure of how sensitive the climate is to this build-up in heat – how much the planet will warm in response to an increase in the amount of greenhouse gases in the atmosphere.

Therefore, in order to argue that humans are not the driving force behind the current global warming, skeptics like Spencer…require that the climate sensitivity to increasing greenhouse gases is low.  The problem with this position is that there are many lines of evidence that the planet will warm between 2 and 4.5 degrees Celsius (°C) if the amount of carbon dioxide (CO2) in the atmosphere doubles.

    All that cabbage in such a small body. Leprechaun flatulence is a possible cause that should be studied further.

    The Arctic ocean is warming up, icebergs are growing scarcer and in
    some places the seals are finding the water too hot, according to a
    report to the Commerce Department yesterday from Consulafft, at
    Bergen, Norway. Reports from fishermen, seal hunters and explorers
    all point to a radical change in climate conditions and hitherto
    unheard-of temperatures in the Arctic zone. Exploration expeditions
    report that scarcely any ice has been met as far north as 81 degrees
    29 minutes. Soundings to a depth of 3,100 meters showed the gulf
    stream still very warm. Great masses of ice have been replaced by
    moraines of earth and stones, the report continued, while at many
    points well known glaciers have entirely disappeared.

    Very few seals and no white fish are found in the Eastern Arctic,
    while vast shoals of herring and smelts which have never before
    ventured so far North, are being encountered in the old seal fishing
    grounds. Within a few years it is predicted that due to the ice melt
    the sea will rise and make most coastal cities uninhabitable.

    This report was from November 2, 1922, as reported by the
    Associated Press and published in the Washington Post

    Very nice truth!
