If you do the same for 31 year averages, 32 year averages, 33 year averages, etc., on on through at least 70 year averages, you continue to find an indisputable trend of climate warming — even if you dismiss the land data as flawed because of the use of daily extremes rather than a more robust indication of the daily mean.

That given, I have long thought that the notion of a «global average temperature» (GAT) constructed from a sparse set of mixed quality data, statistically infilled (and outfilled) spatially and temporally to try to simulate global coverage is poorly suited to discerning trends presumably based on thermodynamics of the global climate system (GCS).
