Phil Jones email of July 5, 2009 says at 15 years we should "get worried."

"New UK Met Office global temperature data confirms that the world has not warmed in the past 15 years.

Analysis by the Global Warming Policy Foundation (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.) ...

We also note a comment in an email sent by Professor Phil Jones of the University of East Anglia Climatic Research Unit: “Bottom line – the no upward trend has to continue for a total of 15 years before we get worried.” [sent July 5, 2009].

Whether the global temperature standstill of the past 15 years continues or is replaced by warming, as the IPCC predicts, only future data will tell. In the meantime the length of the standstill means that the challenge it offers for models of future climate prediction, and explanations for past warming, cannot be ignored."...via Climate Depot
