Climate alerters Concealed global temperature anomalies Declining despite increasing atmospheric CO2 – Is it increasing because of that?

Essay by Larry Hamlin

NOAA publishes global climate report for the end of 2021 highlights that its global temperature anomalies show 2021 as the sixth-highest of all recorded. NOAA’s global annual measurement for 2021 is 0.84 degrees Celsius.

NOAA has chosen to highlight that the annual temperature anomaly in 2021 within the top 10 recorded years is as follows:

“The the year that culminates is the sixth warmest year record for a globe with a temperature 0.84°C (1.51°F) above the 20th century average. The years 2013–2021 both rank among the ten warmest years recorded. record “.

What NOAA did not highlight is that the global temperature anomaly results at the end of 2021 mark a continued decline in their global temperature anomaly measurements, which have now declined over the past 6 years since 2016 peak year as shown in the chart below. These decline measurements are a complete mockery of climate alarmists who have recently been scientifically unsupported, unsupported by statements that propagate a “climate emergency.” Queen”.

The decline in NOAA global anomalous temperature measurements over the past 6 years since peak year 2016 is shown in more detail in the truncated NOAA graph below.

NOAA’s annual peak global temperature anomaly measurement was at the end of 2016, currently displayed as 0.99 degrees Celsius (second highest year in 2020 is 0.98 degrees Celsius) compared to the measurement results. The annual anomaly at the end of 2021 is 0.84 degrees Celsius with +/- 0.15 degrees Celsius confidence. This year by the end of 2021, the decrease in the global temperature anomaly measurement is equivalent to a decrease in temperature. The decline in global abnormal temperature measurement has been 15% since the 2016 peak year.

Furthermore, NOAA analysis clearly establishes that monthly and yearly global anomalous temperature measurement behaviors are tightly controlled by El Niño and La Niño events (parts highlighted in red and blue). blue of the respective NOAA graph) are natural and non-anthropogenic climate phenomena that have contributed to atmospheric CO2 levels.

NOAA overstated the significance of monthly and yearly temperature anomalies with differences as small as +0.01 degrees Celsius to underpin the “warmest-ever temperature” enhancement. to date” as has been done for anomalous temperature data for July 2021 although the confidence level for this is +/- 0.19 degrees Celsius as discussed in the WUWT papers here and here. In addition, and more significantly, no other global anomalous temperature measurement systems including NASA GISS, UK Met Office, UAH and RSS support NOAA’s “hottest temperature ever” claim for July. .

NOAA’s July 2021 Global Temperature Abnormal Update initially declared the July global temperature anomaly as 0.93 degrees Celsius, then changed that in the monthly temperature anomaly update. 8 to 0.92 degrees Celsius but the November temperature anomaly update changed the July temperature anomaly again back to 0.93 degrees Celsius.

NOAA performs extensive anomalous temperature measurement updates on a monthly basis where a large number of previous temperatures are repeatedly changed. For example, NOAA’s August 2021 temperature anomaly update compared to NOAA’s November 2021 temperature anomaly update shows that between 1954 and 2021, more than 250 anomalies monthly increases of +0.01 degrees Celsius with about half of these increases being made between 1992 and 2021.

As a result, more than a third of monthly anomalies between 1992 and 2021 were adjusted for 0.01 degrees Celsius in the midst of NOAA’s August and November anomaly updates. These large numbers of continuous incremental adjustments lead to increasing variation in reported data values, such as the highest annual abnormal global temperature readings as originally reported for at the end of 2016 increased from 0.94 degrees Celsius to 0.99 degrees Celsius by the end of the year 2021 Report.

In addition, these updated NOAA temperature anomalies from August to November 2021 for years prior to 1954 are also adjusted, but in this case always down to -0.01°C for more than 100 monthly data values ​​prior to 1954.

The justification of NOAA’s large number of never-ending up-and-down adjustments that always degrade long-standing historical data and always inflate more recent historical data is extremely confusing and revealing. concerns that these changes are driven by climate alarm politics (especially by Biden and other Democratic administrations) than by credible science.

The annual global decline in anomalous temperatures from late 2016 to late 2021 has occurred despite continued increases in global atmospheric CO2 levels as shown in the graph below. shows that the concentration of CO2 in the atmosphere is increasing from 402 ppm to 417 ppm based on measurements from the Mauna Loa Observatory. Of course, erroneous and failed climate “models” will describe the anomalous results of increasing global temperatures from this data.

In addition to NOAA’s decline in global anomalies since late 2016, all other global anomalies used by climate scientists worldwide show measurements The global temperature anomaly decreased between 2016 and 2021 as shown in the graph below which measures the global temperature anomaly on the surface of the system from NASA GISS and Met Office in the UK and for satellite global anomalous temperature measurement systems from UAH and RSS corresponding.

Despite the usual exaggerations by conventional climate alarmists by NOAA and NASA in their 2021 annual reports trying to mask the apparent trends in global temperature anomalies, while levels Global atmospheric CO2 is continuing to climb the annual global temperature anomaly results for the end of 2021 and the past six years do not support and in fact clearly oppose the recent climate alarmist’s claims. that we are in a “climate emergency” due to man-made CO2 missions.

Actual measurements of global temperature anomalies by NOAA, NASA, UK Met Office, UAH and RSS all show a downward trend compared to an upward trend in climate “computer modeled” temperature anomalies with these speculative “pattern” trends are not supported by the measurement data. The eventual COP26 climate alarm system failure appears to be a clear fit based on these latest global anomalous temperature measurements.

However, all of these political climate alarmist-driven COP cabs starting in the 1990s have the aforementioned spectacular failure record.
