Arctic cooling coming

No area of the earth gives Warmists erections like the Arctic. They are always talking about it. For reasons that I have never tried to follow, they say that the effects of global warming will be greatest and most significant there. And since the ice-cover there has always waxed and waned, they can always cherry-pick a particular period of years that suits their theories.

Every now and again, however, somebody nastily looks at the whole temperature record, not just a selected slice of it. And the latest example of that is woeful news for the Warmists. Some Norwegian scientists have gone to the town of Longyearbyen in Norway's far North (bordering the Arctic circle) and checked out the temperature record there -- dating from 1912.

They found two things: That the temperature changes there are cyclic and the cycles are mainly explained by the activity of the sun. That enables them to predict Arctic COOLING from now to the year 2020. Abstract below

The long temperature series at Svalbard (Longyearbyen) show large variations, and a positive trend since its start in 1912. During this period solar activity has increased, as indicated by shorter solar cycles. The temperature at Svalbard is negatively correlated with the length of the solar cycle. The strongest negative correlation is found with lags 10F12 years.

The relations between the length of a solar cycle and the mean temperature in the following cycle, is used to model Svalbard annual mean temperature, and seasonal temperature variations. Residuals from the annual and winter models show no autocorrelations on the 5 per cent level, which indicates that no additional parameters are needed to explain the temperature variations with 95 per cent significance.

These models show that 60 per cent of the annual and winter temperature variations are explained by solar activity. For the spring, summer and fall temperatures autocorrelations in the residuals exists, and additional variables may contribute to the variations. These models can be applied as forecasting models. We predict an annual mean temperature decrease for Svalbard of 3.5±2 degrees Celsius from solar cycle 23 to solar cycle 24 (2009-20) and a decrease in the winter temperature of around 6 degrees Celsius.
