No Warming for 16 years


Dr David Whitehouse, writing for the Global Warming Policy Foundation (GWPF) argues that there has been no warming for 16 years and projecting from these figures the temperature in 2100 would only rise by around 1ÂșC.
The UK Met Office and the Climatic Research Unit of the University of East Anglia have released the data for December in their Hadcrut3 and Hadcrut4 global temperature datasets. This completes the data for 2012 and allows it to be placed into context with the preceding years.
Statistically there has been no change in the average annual temperature of the globe since 1997 meaning that the standstill is now 16 years. The latest five-year average of Hadcrut3 and Hadcrut4 data shows a decline for the first time.
After examining a little graph trickery, he moves on to temperature projection.
It is interesting to note that since the IPCC says anthropogenic influences on the climate dominate – post 1980 – the global temperature has risen by 0.3 – 0.4 degrees C in a third of a century. If this rate were sustained then by 2100 the global temperature would have risen by another 0.9 – 1.1 degrees C. This is much less than the much touted 2 degrees C safety limit. Of course many maintain that in the past 16 years natural climatic influences have been acting in the opposite direction to man-made global warming. They expect these influences to diminish and an average rate of warming of 0.2 degrees per decade to occur.
