Global Warming and the test of science II

The scientific method demands that theories be tested.  The UK Meteorological Office is an advocate of global warming and they use their computer models to predict weather.  Steven Goddard reviews how well their models have passed the test of experiment:
The UK Met Office famously forecast this past winter to be “milder than average.

25 September 2008

The Met Office forecast for the coming winter suggests it is, once again,
likely to be milder than average.

Seasonal forecasts from the Met Office are used by many agencies across government, private and third sectors to help their long-term planning.

The meteorological winter is over, and the official results are in :

The UK had its coldest winter for 13 years, bucking a recent trend of mild temperatures, the Met Office has said.

The average mean temperature across December, January and February was 3.1C - the lowest since the winter beginning in 1995, which averaged 2.5C.

This missed forecast falls on the heels of two consecutive incorrect summer forecasts , both of which were forecast to be warm but turned out to be complete washouts.
So far, it appears that the predictions made by global warming skeptics have been more reliable.

PREVIOUSLY, the US NSIDC's predicted a 50/50 chance of an ice-free North Pole and that did not happen.  Some basics of the global warming controversy were addressed by Dr. Syun-Ichi Akasofu here where he addresses the failure of IPCC predictions.  (The limited science expertise on the UN IPCC panel was discussed here.  In contrast with the failures of global warming models, experiments testing the influence of solar and cosmic effects on weather have shown positive results.
