THE GLOBAL WARMING POLICY FOUNDATION
New UK Met Office global temperature data confirms that the world has not warmed in the past 15 years.
Analysis by the GWPF of the newly released HadCRUT4 global temperature database shows that there has been no global warming in the past 15 years - a timescale that challenges current models of global warming.
The graph shows the global annual average temperature since 1997. No statistically significant trend can be discerned from the data. The only statistically acceptable conclusion to be drawn from the HadCRUT4 data is that between 1997 – 2011 it has remained constant, with a global temperature of 14.44 +/- 0.16 deg C (2 standard deviations.)
The important question is whether 15 years is a sufficient length of time from which to draw climatic conclusions that are usually considered over 30 years, as well as its implications for climate projections. MORE.........................
