Global Warming: A Classic Case of Alarmism
The global temperature has been rising at a steady trend rate of 0.5°C per century since the end 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.
There was a cooling scare in the early 1970s at the end of the last cooling phase. The current global warming alarm is based on the last warming oscillation, from 1975 to 2001. The IPCC predictions simply extrapolated the last warming as if it would last forever, a textbook case of alarmism. However the last warming period ended after the usual thirty years or so, and the global temperature is now definitely tracking below the IPCC predictions.
So there you have it. How much more do we need to discuss this? In ten years you will hear the scientists saying that all the "damage" we've done has over balanced the system causing cooling. Mark my words.
So if you want to believe the planet is doomed, go ahead. You'll get more donations for your cause, or money for your technologies to prevent it. It's a classic "the sky is falling" and you have to do something about it.
