  Relations between the length of a sunspot cycle and the average temperature
in the same and the next cycle are calculated for a number of meteorological
stations in Norway and in the North Atlantic region. No significant trend is
found between the length of a cycle and the average temperature in the same
cycle, but a significant negative trend is found between the length of a cycle
and the temperature in the next cycle. This provides a tool to predict an
average temperature decrease of at least 1.0 "C from solar cycle 23 to 24 for
the stations and areas analyzed. We find for the Norwegian local stations
investigated that 25-56% of the temperature increase the last 150 years may be
attributed to the Sun. For 3 North Atlantic stations we get 63-72% solar
contribution. This points to the Atlantic currents as reinforcing a solar
signal.
