Climate: bull or bear?

Just as the great bull run that could have no end, ended, another unthinkably big bubble quivers. Technical indicators are quietly being tripped that suggest the bull run in global temperatures may be toying with a reversal. Could another large human institution dependent on complex models be headed for it’s ‘Lehman Bros’ moment? [...]

Global warming: a classic case of alarmism

This is a Guest Post by Dr David Evans

The big temperature picture. Graph and insight from Dr Syun Akasofu (2009 International Conference on Climate Change, New York, March 2009).

The global temperature has been rising at a steady trend rate of 0.5°C per century since the depths of the little ice age in the 1700s (when the Thames River would freeze over every winter; the last time it froze over was 1804). On top of the trend are oscillations that last about thirty years in each direction:

1882 – 1910    Cooling 1910 – 1944    Warming 1944 – 1975    Cooling 1975 – 2001    Warming

In 2009 we are where the green arrow points, with temperature leveling off. The pattern suggests that the world has entered a period of slight cooling until about 2030.
