NOAA has updated its Global Time Series Average Temperature Anomaly data through May 2024 with the results clearly indicating that the year 2023/2024 El Nino event continues to weaken as demonstrated by the data presented and discussed below.

The NOAA data presented below uses a graph display interval of a 30-year period from January 1995 through May 2024 to allow greater visibility of the monthly changes occurring during this most recent climate data interval.

The NOAA Global Land and Ocean average temperature anomaly data is shown below with both graph and table formats.

The NOAA Global Land and Ocean average temperature anomaly through May 2024 has further declined from the November 2023 peak EL Nino value of 1.43 degrees C to 1.18 degrees C (338^th out of 353 measured values) with this outcome also being below the April 2024 result of 1.30 degrees C (345^th of 353 measured values) indicating this most recent El Nino event continues to weaken.

The NOAA Global Land updated average temperature anomaly data is shown below in both graph and table format.

The Global Land average temperature anomaly through May 2024 has further declined from the prior February 2016 El Nino peak value of 2.53 degrees C (the highest ever measured NOAA Global Land anomaly value) to 1.63 degrees C (316^th out of 353 measured values) with this outcome also below the April 2024 result of 1.93 degrees C (336^th out of 353 measured values) clearly showing that this most recent El Nino event continues to weaken.

This latest NOAA Global Land average temperature anomaly data continues to confirm that Earth’s 8+ billion people (that reside on land) have experienced declining Global average temperature anomaly outcomes since the February 2016 El Nino peak value (that occurred over 8 years ago) indicating that humanity is not in a climate crisis.

This outcome establishes that climate alarmist hype claiming that the Earth is facing a “climate emergency” is unsupported by NOAA’s Global Land average temperature anomaly measured data as presented above in NOAA’s graph and table data values.

There are many other NOAA Global region average temperature anomaly measured data results that also establish that peak measured Global region average temperature anomaly values occurred years ago.

 NOAA’s updated Northern Hemisphere Land average temperature anomaly measured data is shown below in both graph and table format.      

NOAA’s data for the Northern Hemisphere Land region has a peak average temperature anomaly value that occurred in February 2016 at 3.17 degrees C (during the prior El Nino event) with the latest May 2024 anomaly value measured far below the prior peak value at 1.79 degrees C (293^rd highest value of 353 measured values) which is also below the April 2024 measurement value of 2.49 degrees C (344^th highest value of 353 measured values).

 NOAA’s updated region measurement data for the average temperature anomaly for Asia is shown below in both graph and table formats.

NOAA’s data shows that the May 2024 average temperature anomaly value of 1.57 degrees C (242^nd of 353 measured values) is far below the Asia region peak average temperature anomaly value of 4.11 degrees C measured in February 2020. as well as the April 2024 value of 2.65 degrees C (331^st of 353 measured values).

NOAA’s updated average temperature anomaly for the Oceania region measured data is shown below in both graph and table formats.

NOAA’s data shows that the May 2024 average temperature anomaly value of 1.29 degrees C (303^rd out of 353 measured values) is well below the Oceania peak average temperature anomaly result of 2.21 degrees C in December 2019.  

NOAA’s updated average temperature anomaly data for the East N. Pacific region measured outcomes are shown below in both graph and table format.

NOAA’s data shows that the May 2024 average temperature anomaly value of 0.80 degrees C (271^st out of 353 measured values) is well below the peak East N Pacific average temperature anomaly result of 1.79 degrees C in October 2015.

NOAA’s updated average temperature anomaly data for the Hawaiian region measured outcomes are shown below in both graph and table format.

NOAA’s data shows that the May 2024 average temperature anomaly value of 0.37 degrees C (172^nd out of 353 measured values) is well below the Hawaiian region peak average temperature anomaly result of 1.76 degrees C in September 2015.

NOAA’s updated average temperature anomaly data for the Arctic region measured outcomes are shown below in both graph and table format.

NOAA’s data shows that the May 2024 average temperature anomaly value of 1.79 degrees C (224^th out of 353 measured values) is well below the Arctic region peak average temperature anomaly result of 5.00 degrees C in January 2016 as well as below the April 2024 value of 2.57 degrees C (287^th out of 353 measured values).

 NOAA’s updated average temperature anomaly data for the Antarctic region measured values are shown below in both graph and table format.

NOAA’s data shows that the May 2024 average temperature anomaly value of 0.55 degrees C (265^th out of 353 measured values) is well below the Antarctic peak average temperature anomaly result of 2.25 degrees C in August of 1996 nearly 3 decades ago.

Additionally, NOAA’s updated USCRN (a state-of-the-art accurate surface temperature network free of localized heat biases addressed here) Maximum Temperature Anomaly data for the Contiguous U.S. through May 2024 (shown below) demonstrates there is no established upward temperature anomaly trend since at least the year 2005.

Furthermore, the peak May maximum temperature anomaly in the U.S. occurred in May 1934 at 5.66 degrees F versus 1.22 degrees F in May 2024 (highlighted in red) as shown above.

The latest NOAA Global Times Series average temperature anomaly data (updated through May 2024) as well as NOAA’s latest USCRN Contiguous U.S. anomaly data (also updated through May 2024) do not support and in fact contradict climate alarmists flawed claims that the Earth is experiencing a climate emergency.
