From ClimateRealism<\/a><\/p>\n\n\n\n

Editor\u2019s Note:<\/strong> The media regularly reports on temperature extremes, whether it is local, statewide, or global. They are especially guilty of hyping supposed \u201chottest\u201d days, months, years, or decades. Climate Realism has covered the false or misleading hottest year claims across dozens of articles, for example here<\/a>, here<\/a>, and here,<\/a> are prime examples of the hottest ever hype<\/a> that Climate Realism has debunked. When it comes to climate, the mainstream media often only report on the average global temperature rather than look at or track to high temperature and low temperature datasets. As Larry Hamlin describes below, the media completely misses a good part of the temperature story because they ignore these parts of the temperature record, which tell a far less alarming story about climate. Worse than that, now the media has been relying on climate models<\/a> rather than actual data to determine their \u201chottest ever\u201d claims.<\/em><\/p>\n\n\n\n

Guest essay by Larry Hamlin<\/strong><\/p>\n\n\n\n

NOAA\u2019s U.S. contiguous U.S. summer (June through August) measured minimum and maximum temperatures trends<\/strong> over the period 1895 through 2024 (shown below from NOAA\u2019s Climate at a Glance Times series data website) show clear and distinct differing temperature trend increasing growth compared to the calculated average temperature trend outcome<\/strong>.<\/p>\n\n\n\n

The minimum temperature trend outcomes after 1985 climb significantly faster than do the maximum measured temperature trend outcomes. U.S. population data shows an increase of about 100 million during the 1980 to 2023 period.<\/p>\n\n\n\n

Since the average temperature is not a measured value but instead the calculated mathematical average of the minimum and maximum measured temperatures {(TMax + TMin)\/2} the average temperature calculated trend outcome is controlled and dominated by the much larger increase occurring in the minimum measured temperature trend versus the maximum measured temperature trend.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This differing trend distinction can be more clearly seen in the graphs below where the NOAA Climate at a Glance website time period interval is broken into the time intervals from 1895 to 1950 and 1950 to 2024 (where the Tavg value is controlled by Tmin not Tmax) respectively as shown below.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

This outcome is consistent with and reflects the results of Dr. Spencer\u2019s recent study shown below and found\u00a0here<\/a>.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Dr. Spencer also provided another study which displayed in graphical form the UHI impacts of U.S. and Global wide temperatures during the period June 1850 through June 2023 as shown below and found\u00a0here<\/a>.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n
\"\"<\/figure>\n\n\n\n

In addition to large population growth UHIs acting as a prime driver of rising calculated Tavg temperature outcomes, these temperature measurements are also being significantly impacted by NOAA\u2019s improper siting of thousands of temperature measurement stations.<\/p>\n\n\n\n

These thousands of improperly sited temperature measurement devices do not meet NOAA\/NWS siting standards and are located far too close to artificial heat sinks that falsely increase both maximum and minimum temperature measurements<\/strong> as addressed in detail here<\/a> with an example clearly illustrating this huge system wide measurement problem shown below.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

As noted in this report (page 18) the year 2019 Oak Ridge National Laboratory measurement station data accuracy experiment showed that flawed station siting temperature measurement impact outcomes were much greater during the evening periods (heat sink contributions to minimum temperatures were a factor of 3 larger than maximum day temperature contributions) versus during the day.<\/strong><\/p>\n\n\n\n

NOAA bases its evaluation of U.S. and global average temperature anomaly value changes over time by using and comparing the calculated Tavg values over time<\/strong>.<\/p>\n\n\n\n

As indicted by the temperature measurement graphs and studies noted above NOAA\u2019s 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.<\/strong><\/p>\n\n\n\n

This results in NOAA\u2019s calculated Tavg assessments of increasing temperature anomalies over time being a flawed and exaggerated claim driven by NOAA\u2019s measurement siting inadequacies and population growth driven UHI impacts \u2013 and not \u201cclimate change\u201d.<\/strong><\/p>\n\n\n\n

This outcome is also applicable to NOAA\u2019s global wide calculated Tavg temperature anomaly increasing trend assessments as well.    <\/strong><\/p>\n\n\n\n
