Weather Eye with John Maunder

A superimposed graph of five global monthly temperatures January 1979 to August 2014 is shown below.

As the base period differs for the individual temperature estimates, they have all been normalised by comparing with the average value of the initial 120 months (10 years) from January 1979 to December 1988.

The heavy black line represents the simple running 37 month mean of the average of all five temperature records. The small numbers shown in the lower right corner represent the temperature anomaly relative to the individual 1979-1988 averages.

Below is a link which will take you directly to a monthly newsletter with global meteorological information updated to August/September 2014:

The website is produced by Ole Humlum, Professor of Physical Geography, Institute of Geosciences, University of Oslo.

All five global temperature estimates presently show an overall stagnation, at least since 2002. There has been no increase in global air temperature since 1998, which however was affected by the oceanographic El Niño event.

Professor Humlum considers that this stagnation does not exclude the possibility that global temperatures will begin to increase again later.

On the other hand, it also remain a possibility that the Earth just now is passing a temperature peak, and that global temperatures will begin to decrease during the coming years. Time will show which of these two possibilities is correct.
