As indicted by the temperature measurement graphs and studies noted above NOAA’s contiguous U.S. calculated Tavg increasing trend values since about 1985 are clearly driven upward by station measurement siting flaws and UHI Tmin outcomes versus Tmax measured outcomes.

This results in NOAA’s calculated Tavg assessments of increasing temperature anomalies over time being a flawed and exaggerated claim driven by NOAA’s measurement siting inadequacies and population growth driven UHI impacts – and not “climate change”.

This outcome is also applicable to NOAA’s global wide calculated Tavg temperature anomaly increasing trend assessments as well.
