The Computation Of A Global Average Surface Temperature Anomaly

The gold standard of global warming (despite its inadequacies relative to the assessment of trends in the ocean heat content) is the global average surface air temperature anomaly and its annual trend over time. For example, it is claimed that a +2C anomaly must … Continue reading

Recent Papers On The Uncertainty and Biases In the Long Term Assessment Of The Global Average Surface Temperature Trend

The  multi-decadal global surface temperature trend is used (inappropriately; e.g. see) as the primary metric to diagnose the magnitude of global warming and cooling. This post lists major unresolved issues with the use of this surface temperature trend metric, along with examples … Continue reading
