Guest essay by Larry Hamlin
NOAA has updated its U.S. Temperature Index Contiguous National Temperature Anomaly data and its national, state, county, and city temperature data (as well as other climate data parameters) through April 2024.
Shown below is NOAA's National Time Series USCRN Maximum Temperature Anomaly dataset for the contiguous United States, with data updated through April 2024.
This NOAA data is clear notes that there is no uptrend anomaly signature for the contiguous US monthly maximum temperature anomalies for the period January 2005 to April 2024.
NOAA's USCRN The maximum temperature anomaly value in April 2024 is 1.91 degrees F (highlighted in red above) with the highest recorded USCRN value in April in April 2006 at 3.62 degrees F.
Furthermore, the April 2024 maximum anomaly value is only the third highest recorded April maximum temperature anomaly in the period January 2005 to April 2024.
NOAA's latest data on the maximum temperature anomaly in the contiguous United States clearly refutes the politically contrived, exaggerated climate alarmism hype that we are experiencing a “climate emergency.”
Shown below are NOAA's National Time Series of contiguous April maximum temperatures in the United States from 1895 to April 2024, making it clear that there is nothing remarkable about the April 2024 result highlighted in red below.
April 2024 is just that 116th highest April high temperature of 130 consecutive US April high temperatures Temperature months since 1895 as shown below with Maximum temperatures in the previous years 1895, 1910, 1915, 1925, 1930, 1934, 1946, 1954, 1977, 1981, 1985, 1987, 2006 (highest value) and 2012 above the value in 2024.
NOAA's maximum April temperatures in the contiguous US between 1895 and 2024 clearly refutes the exaggerated and politically motivated claims of climate alarmists that we are experiencing a “climate emergency”..
Shown below are NOAA's National Time Series of contiguous January-April U.S. maximum temperatures from 1895 to April 2024, which again show nothing notable relative to the January-April 2024 result, highlighted in red below.
The maximum temperature from January to April 2024 is the 123rd highest of 130 contiguous US measurements with Previous year results from 1946, 1986, 1990, 2000, 2006, 2012 (highest value), 2016 and 2017 exceeding the 2024 value as shown below.
NOAA's maximum temperatures in the contiguous United States from January to April between 1895 and 2024 clearly refutes the exaggerated and politically motivated claims of climate alarmists that we are experiencing a “climate emergency”..
Shown below are NOAA's national time series of contiguous U.S. absolute maximum temperatures for all months from 1895 to April 2024, which again show nothing notable relative to the April 2024 result, highlighted in red below.
April 2024 only the 808th highest month of 1552 highest months measured since 1895 as shown below.
NOAA's contiguous US maximum temperature data for all months since 1895 refuted Climate alarmists make exaggerated and politically motivated claims that we are experiencing a “climate emergency.”.
NOAA's statewide time series data for maximum temperatures in California for the month of April between 1895 and 2024 is shown below and, again, shows nothing notable relative to the April 2024 result, highlighted in red below.
April 2024 is just that 86th highest April high temperature out of 130 highest April temperatures measured temperatures since April 1895, as shown below.
NOAA's California Statewide Time Series maximum temperature data for the April months between 1895 and 2024 refutes the exaggerated and politically motivated claims of climate alarmists that we are experiencing a “climate emergency.”.
Additionally, this NOAA database also notes this none One of the 48 contiguous U.S. states recorded an April peak month with record high temperatures in 2024.
The The same result also applies to Alaska, as shown below with the April 2024 result being only the 80th highest maximum temperature among the 100 highest April months.
Shown below are NOAA's statewide time series for California's maximum temperatures for all months between 1895 and 2024, which again show nothing out of the ordinary with the April 2024 result, highlighted in red below.
April 2024 is just that 745th highest maximum temperature of 1552 highest measured monthly temperatures since 1895, as shown below.
Maximum temperature data from NOAA's California Statewide Time Series for all months between 1895 and 2024 refutes the exaggerated and politically motivated claims of climate alarmists that we are experiencing a “climate emergency.”.
Below are the NOAA City Time Series data for Los Angeles, California, with maximum temperature data for the month of April 2024 for the period starting in 1945, and again show nothing notable in relation to the April 2024 result, highlighted in red below is.
April 2024 is only the 49thHighest April high of 80 highs measured monthly temperatures in April since 1945, as shown below.
NOAA's City Time Series for Los Angeles, California, maximum temperature data for the April months between 1945 and 2024 refuted Climate alarmists make exaggerated and politically motivated claims that we are experiencing a “climate emergency.”.
NOAA's City Time Series for Los Angeles, California shows the maximum temperatures for all months in the period 1944 to 2024 and again shows nothing notable with respect to the April 2024 result, highlighted in red below.
April 2024 is only the 359thhighest maximum temperature of 957 highest measured monthly temperatures since August 1944, as shown below.
NOAA's City Time Series for Los Angeles, California, maximum temperature data for all months between August 1944 and April 2024 refutes the exaggerated and politically motivated claims of climate alarmists that we are experiencing a “climate emergency.”.
NOAA recently released its “Assessing the U.S. Climate in April 2024” report (see below), which did not provide detailed temperature data as addressed in this essay (using NOAA's own extensive datasets) and instead provided nebulous “color” charts and generalized statements were silent about what their own data shows on measured temperature results, which clearly do not indicate that we are experiencing a “climate emergency,” as discussed in detail above.
Shown below is one of the charts depicting the “Mean Temperature Deviations from Average” for the contiguous United States, but does not provide specific temperature data that provides insight into the large natural variations in measured temperature results that occur over time, such as stated in This paper is based on data from NOAA.
A similar chart (see below) is also provided that shows the “deviations of mean temperature from average” for the period January to April 2024, but again does not provide specific temperature measurement data that provides useful insights into the patterns and extent of the natural Temperature behavior provides time as reported in this paper using NOAA data.
What is particularly concerning is that this NOAA report did not provide the clearest data on temperature anomalies in the contiguous US (see below and addressed in the essay above) that clearly demonstrate that there is no “climate emergency.”
The NOAA temperature data discussed in detail in this essay does not support and clearly refutes the climate alarmist hype that we are experiencing a “climate emergency.”
