It appears as though internal variability has offset warming over the last 15 or so years...this is gibberish - but then warmists are notoriously poor statisticians, as Dr. Edward Wegman demonstrated years ago when he made the supposed "hockey stick effect" disappear by correcting the statistical analysis which had hidden previous warming trends - apparently the argument is that the upward warming trend which the warmists hope is there is now hidden by the variability in temperature over the last nineteen - not fifteen - years and that once the variability decreases the rise in temps will become obvious - more likely, the measurements will "regress to the mean" and the temperatures will remain more consistently right around the average unchanged value where they are today.
The real problem the warmists have is that they put all their eggs in the CO2 basket, when in fact they have no idea what and how many different variables affect long range temperatures, let alone how these variables act and how they interact with each other. We are now undergoing one of the longest periods of reduced sunspot activity on record - such a reduction might be expected to reduce our temperatures somewhat, in spite of what the CO2 measurements are - but its occurrence and duration are unpredictable and to think it possible to determine all such occurrences of this and other possible variables over the next fifty years to predict more than approximately what the climate will be is a fools erand.....
