Initial Notes: This post contains graphs of running trends in global surface temperature anomalies for periods of 12+ and 16 years using GISS Land-Ocean Temperature Index (LOTI) data. They indicate that we have not seen a warming hiatus this long since the 1970s.

Much of the following text is boilerplate. It is intended for those new to the presentation of global surface temperature anomaly data.

GISS LAND OCEAN TEMPERATURE INDEX (LOTI)

Introduction: The GISS Land Ocean Temperature Index (LOTI) data is a product of the Goddard Institute for Space Studies. Starting with their…
