“The devil is in the detail” is a very wise observation.
But, occasionally a subject emerges where the devil is in the premise of an
argument. Consider the following.
A recent gathering by those who aim to fight climate change
pledged a sum of about $200 billion to help finance the world’s efforts to
prevent climate change. What is the background to this international effort?
Scientists have gathered enough knowledge to build up a
picture about climate change through millions of years on Planet Earth. There
is enough evidence to suggest that Planet Earth creates cyclical Ice Age
periods lasting approximately 100,000 years. These periods are interleaved by
warmer climate periods, lasting between 15,000 and 20,000 years. During an Ice Age period, most of North
America and Europe, for example, were covered
in a blanket of ice which in warmer climactic periods recede, even the poles
were occasionally free of ice. Greenland was
at some time a green land as a result. Our
current warmer climate period has already lasted about 18,000 years and,
scientifically, our period is still considered to be at the end of an ice age
due to the fact that two poles are still covered in ice.
So, the proposition is that we, humanity, have interfered
with this cyclical climate change by burning fossil fuels during the past 250
years, causing a temperature rise of between 1 to 4 degrees depending on who is
talking. Furthermore, the proposition
goes, we can prevent this climate change by burning 30-40% less of fossil fuel
and replacing the energy deficiency by green, renewable energy sources, such as
windmills and tidal energy power stations among other measures. Looking for “the devil” in this argument I do
not think that we need to bother with the detail.
If I may lower the tone of this submission, I have a close
second proposal for preventing global warming.
We should lower the temperature of the Sun by firing icebergs at
it at high speed, probably the speed of light, to prevent the icebergs melting
before they hit the target. This proposition will only cost 100,000 trillion
dollars and would provide continued employment to Al Gore and several
scientists and engineers, not to mention lawyers.
