Another paper confirms “the pause” in global warming – cites issues with methods of obtaining average temperature

Watts Up With That?

Spatiotemporal Divergence of the Warming Hiatus over Land Based on Different Definitions of Mean Temperature

  • Chunlüe Zhou & Kaicun Wang

Abstract

Existing studies of the recent warming hiatus over land are primarily based on the average of daily minimum and maximum temperatures (T2). This study compared regional warming rates of mean temperature based on T2 and T24 calculated from hourly observations available from 1998 to 2013. Both T2 and T24 show that the warming hiatus over land is apparent in the mid-latitudes of North America and Eurasia, especially in cold seasons, which is closely associated with the negative North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) and cold air propagation by the Arctic-original northerly wind anomaly into mid-latitudes. However, the warming rates of T2 and T24 are significantly different at regional and seasonal scales because T2 only samples air temperature twice daily…
