An Excellent Example Of The Reason We Need To Focus On Regional Circulation Patterns And Not A Global Average Surface Temperature Trend

Climate Science has made as one of its main conclusions that The needed focus for the study of climate change and variability is on the regional and local scales. Global and zonally-averaged climate metrics would only be important to the … Continue reading

A Significant Warm Bias With The Diagnosis Of A Global Average Surface Temperature Anomaly To Diagnose Global Warming – Part II From Our JGR Paper

Part I of this series of weblogs (see), discussed the serious limited value of the use of a global average surface temperature anomaly to diagnose the global radiative imbalance (i.e., global climate heat system changes). In Part II, we discuss another … Continue reading

Further Evidence On The Need To Expand The Climate Metrics Beyond A Focus On the Global Average Surface Temperature Trend

A recent paper provides further evidence of why a focus on a global average surface temperature is an ineffective climate metric if the goal is to communictate actual climate responses to scientists, policymakers and the public. The paper by M. … Continue reading

Policymakers Need to Move Beyond the Global Average Surface Temperature Trend as the Primary Climate Change Metric

The focus on a specific increase of the global average surface temperature has become the climate change icon that is reported on frequently in the media (e.g., see “Global warming worst in 20 000 years – report“), in government assessments … Continue reading

Why there is a Warm Bias in the Existing Analyses of the Global Average Surface Temperature

Readers of this weblog know that there have been comments on the warm bias that we have identified, as reported in Matsui and Pielke, GRL, 2005, with respect to the global analysis of surface temperature trends. This is an important … Continue reading
