Identifying the early 2000s hiatus associated with internal climate variability.

ABSTRACT: This study focuses on re-examining the early 2000s hiatus and the associated key components of the global mean surface temperature (GMST) using multiscale statistics for five well-known gridded surface temperature and two reanalysis datasets. The hiatus is characterized as a near-zero trend on the decadal scale corresponding to the maximum P-value via an F-test in statistics. The results reveal that the hiatus exists in both the GMST and global mean air temperature (GMAT) time series, rather than in global warming component, which has maintained an approximately constant rate of change of approximately 0.08 °C/decade over the past three decades. The hiatus's duration is different from that of time series such as 2002-2012/2001-2013/2002-2014 in HadCRUT4, NOAA-old, ERA-Interim and NCEP-R2.
