Chart of the Day

Warming alarmists dismiss current global cooling data as over-influenced by short-term trends that soon will cause temperatures to rise again. Now, in some ways, that's my point: "Climate change is a natural, dynamic process where weather and heat ebb and flow over centuries--there is no single, static, global temperature." Or, as Christopher Booker and Richard North say, "The one thing certain about climate is that it is always changing."

But to the extent such "TOOTSIFs" defend the IPCC's predicted warming, I recommend page 8 of Dr Syun Akasofu's presentation at the Heartland Institute conference:

As Dr. David Evans explains on JoNova:

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). 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.

Agreed.
