All datasets including NASA GISS, UK Met Office & RSS, UAH satellites, show global temperatures declining since 2016 – Warmists spin to conceal cooling temps in 2021

Flashback: Here we go again! Media hypes alleged ‘Hottest year’ declarations – Book excerpt - MIT climate scientist Dr. Richard Lindzen: “If you can adjust temperatures to 2/10ths of a degree, it means it wasn’t certain to 2/10ths of a degree.” - “We’re talking about less than a tenth of degree with an uncertainty of about a quarter of a degree. Moreover, such small fluctuations—even if real—don’t change the fact that the trend for the past 20 years has been much less than models have predicted.”

Larry Hamlin: NOAA published its global climate report for year end 2021 highlighting that its global temperature anomaly measurements showed 2021 being the sixth highest of its recorded measurements. NOAA’s global annual measurement for 2021 was 0.84 degrees C. ... NOAA has exaggerated the importance of both monthly and annual temperature anomaly changes with as small a difference as +0.01 degrees C as a basis for climbing “hottest temperature ever” hype as was done for the July 2021 temperature anomaly data even though the confidence level for this measurement is +/-0.19 degrees C as discussed in WUWT articles here and here. ... 

In addition to NOAA’s global temperature anomaly decline since year end 2016, all other global temperature anomaly measurement systems used by climate scientists worldwide all show declining global temperature anomaly measurements during the period from 2016 through 2021 as shown in the graphs below for surface global temperature anomaly measurement systems from NASA GISS and UK Met Office and for satellite global temperature anomaly measurement systems from UAH and RSS respectively.

"The annual average anomaly for 2021 was +0.134 deg. C above the 30-year mean (1991-2020), which places it as the 8th warmest year in the 43 year satellite record, behind 2016, 2020, 1998, 2019, 2017,2010, and 2015."

Paul Homewood: "It is those computer models that dictated UN climate policies, based on ludicrous projections of rapid warming. In reality, the amount of warming since 1979 has been tiny. Indeed, when you factor in margins of error, there has been no statistically significant warming since 1998. 

You might also note that the satellite data begins in 1979, which just so happens to be the coldest period of the 20thC. At the time it was acknowledged that global temperatures had decline by 0.5C since 1940, which offsets most of the increase since 1979. This decline in temperatures coincides with the cold phase of the Atlantic Multidecadal Oscillation, which has been in warm phase since the 1990s and is soon due to revert to cold."

MARK HODGSON:  "I think this is what is called spin. 2021 must have been a disappointment for climate worriers keen to ratchet up panic and demands for ever-more urgent action to reduce greenhouse gas emissions." The headline “Europe experiences average temperatures during the winter and spring and a year of temperatures outside the ten warmest years” didn’t fit the bill.

Jo Nova: Magical seven-year record wins the Hottest-ever Bingo of 2021. Why does “seven years” suddenly matter? "The last 500 years has been the coldest of the last 5,000." -"Two can play Climate Bingo. In the history of human civilization, we’ve never lived through six centuries that were colder than the last six. Maybe that’s more important than a 7-year hot record in the “blip” at the end?"
