During the Middle Ages climate change had a devastating impact on the world’s population. The Little Ice Age caused famine across the globe, and severely weakened citizens succumbed in their millions to the Black Death and other diseases. In an attempt to understand the problem the great and the good of the scientific and religious communities got together to come up with a solution. Sort of the Medieval equivalent of the IPCC (Intergovernmental Panel on Climate Change). The best idea it seemed was to burn witches. This practice continued for several hundred years and in light of the ending of the Little Ice Age around 1850 it could be claimed to have been something of a success.
Our own IPCC believes that if we could only reduce carbon dioxide emissions then we could end a 150 year rise in world temperatures. To those naysayers who would question the collective wisdom, the head of the IPPC (Ragendra Pachauri) has declared their methods “voodoo science” A campaign of burning 4% of the world’s corn production each year (in the form of ethanol), has been initiated, to mitigate a perceived 3% fall in world corn production due to excess carbon dioxide. Perhaps in a few hundred years we will see whether this has worked. Who know such methods have appeared to be effective in the past.
