“A Cool Look at Global Warming” by Philip R. Wood

There is no opinion, however absurd, which men will not readily embrace as soon as they can be brought to the conviction that it is generally adopted. – (Schopenhauer, Die Kunst Recht zu Behalten)


Facts that we can all agree upon: (global warming advocates and sceptics alike)


Carbon Dioxide (CO2 ) is:

    1. Naturally occurring
    2. Invisible
    3. Odourless
    4. Non-toxic
    5. Necessary for all plant life (photosynthesis)
    6. Emitted by all animal life (breathing etc.)

So why is CO2 called a “pollutant”?

Answer:
Because it is a “greenhouse gas” – even though greenhouse gases make Planet Earth liveable(+14°C average global temperature, rather than -19°C otherwise)


Greenhouse gases, in order of importance, comprise:

    Methane, N2O, etc. 1%
    Carbon Dioxide 2%
    Water vapour 97%

So along with your exhaled breath, fluffy clouds and cow belches are also villainous “pollutants”!


Humankind currently contributes 3% of the Earth’s annual emissions of CO2 into the atmosphere.


The 97% balance of emissions is split between vegetation and soils (53%) and the oceans (44%).


Globally averaged temperature variations between 1850 and 2007 show the emergence from the “Little Ice Age” in the early 1900’s, slight cooling in the 1940’s to the 1970’s, and then warming again since the 1970’s, followed by cooling since 1998.


The Seas are not rising, the Ice is not melting and Cyclones are not increasing.


Everything presented so far has been indisputable empirically observed data. Global warming advocates have no choice but to agree, even if they are reluctant to be open with us all on these matters.


The difference comes when modelling the future: “bulldust in, bulldust out”!
