On a side note: The trends above for the period 1980 to 1995 also show that the recent assertions by David Rose in the Daily Mail and by Judith Curry, according to whom the recent time period was something different to what had been observed before in
the temperature record since the 1970ies are false.
If someone of the ones who state the assertion about the «stopped» global warming, is able to demonstrate that the Null hypothesis above can be successfully rejected, using proper statistical analysis, I will concede that they indeed have statistical evidence at hand, which indicates something has changed significantly in the global
