The post below updates the UAH record of air temperatures over land and ocean. But as an overview consider how recent rapid cooling has now completely overcome the warming from the last 3 El Ninos (1998, 2010 and 2016). The UAH record shows that the effects of the last one were gone as of April 2021, again in November 2021 and February 2022. (UAH baseline is now 1991-2020).
For reference I added an overlay of CO2 annual concentrations as measured at Mauna Loa. While temperatures fluctuated up and down ending flat, CO2 went up steadily by ~55 ppm, a 15% increase.
Furthermore, going back to previous warmings prior to the satellite record shows that the entire rise of 0.8C since 1947 is due to oceanic, not human activity.
The animation is an update of a previous analysis from Dr. Murry Salby. These graphs use Hadcrut4 and include the 2016 El Nino warming event. The exhibit shows since 1947 GMT warmed by 0.8 C, from 13.9 to 14.7, as estimated by Hadcrut4. This resulted from three natural warming events involving ocean cycles. The most recent rise 2013-16 lifted temperatures by 0.2C. Previously the 1997-98 El Nino produced a plateau increase of 0.4C. Before that, a rise from 1977-81 added 0.2C to start the warming since 1947.
Importantly, the theory of human-caused global warming asserts that increasing CO2 in the atmosphere changes the baseline and causes systemic warming in our climate. On the contrary, all of the warming since 1947 was episodic, coming from three brief events associated with oceanic cycles.

March Update Milder Ocean and Land Air Temps
With apologies to Paul Revere, this post is on the lookout for cooler weather with an eye on both the Land and the Sea. While you will hear a lot about 2020-21 temperatures matching 2016 as the highest ever, that spin ignores how fast the cooling set in. The UAH data analyzed below shows that warming from the last El Nino was fully dissipated with chilly temperatures in all regions. Last month both land and ocean showed slightly milder temps
UAH has updated their tlt (temperatures in lower troposphere) dataset for March 2022. Previously I have done posts on their reading of ocean air temps as a prelude to updated records from HadSST3 (which is now discontinued). So I have separately posted on SSTs using HadSST4 2021 Ends with Cooler Ocean Temps This month also has a separate graph of land air temps because the comparisons and contrasts are interesting as we contemplate possible cooling in coming months and years. Sometimes air temps over land diverge from ocean air changes, while last month showed that both air over land and ocean rose slightly.
Note: UAH has shifted their baseline from 1981-2010 to 1991-2020 beginning with January 2021. In the charts below, the trends and fluctuations remain the same but the anomaly values change with the baseline reference shift.
Presently sea surface temperatures (SST) are the best available indicator of heat content gained or lost from earth’s climate system. Enthalpy is the thermodynamic term for total heat content in a system, and humidity differences in air parcels affect enthalpy. Measuring water temperature directly avoids distorted impressions from air measurements. In addition, ocean covers 71% of the planet surface and thus dominates surface temperature estimates. Eventually we will likely have reliable means of recording water temperatures at depth.
Recently, Dr. Ole Humlum reported from his research that air temperatures lag 2-3 months behind changes in SST. Thus the cooling oceans now portend cooling land air temperatures to follow. He also observed that changes in CO2 atmospheric concentrations lag behind SST by 11-12 months. This latter point is addressed in a previous post Who to Blame for Rising CO2?
After a change in priorities, updates are now exclusive to HadSST4. For comparison we can also look at lower troposphere temperatures (TLT) from UAHv6 which are now posted for March. The temperature record is derived from microwave sounding units (MSU) on board satellites like the one pictured above. Recently there was a change in UAH processing of satellite drift corrections, including dropping one platform which can no longer be corrected. The graphs below are taken from the revised and current dataset.
The UAH dataset includes temperature results for air above the oceans, and thus should be most comparable to the SSTs. There is the additional feature that ocean air temps avoid Urban Heat Islands (UHI). The graph below shows monthly anomalies for ocean temps since January 2015.
Note 2020 was warmed mainly by a spike in February in all regions, and secondarily by an October spike in NH alone. In 2021, SH and the Tropics both pulled the Global anomaly down to a new low in April. Then SH and Tropics upward spikes, along with NH warming brought Global temps to a peak in October. That warmth was gone as November 2021 ocean temps plummeted everywhere. A upward bump 01/2022 was reversed in 02/2022 and now temps rise again in 03/2022. Last month warming in the Tropics and NH was moderated by SH ocean air remaining cool.
Land Air Temperatures Tracking Downward in Seesaw Pattern
We sometimes overlook that in climate temperature records, while the oceans are measured directly with SSTs, land temps are measured only indirectly. The land temperature records at surface stations sample air temps at 2 meters above ground. UAH gives tlt anomalies for air over land separately from ocean air temps. The graph updated for March is below.
Here we have fresh evidence of the greater volatility of the Land temperatures, along with extraordinary departures by SH land. Land temps are dominated by NH with a 2021 spike in January, then dropping before rising in the summer to peak in October 2021. As with the ocean air temps, all that was erased in November with a sharp cooling everywhere. Land temps dropped sharply for four months, even more than did the Oceans. Now in March all land regions warmed pulling up the global anomaly.
The Bigger Picture UAH Global Since 1980
The chart shows monthly anomalies starting 01/1980 to present. The average monthly anomaly is -0.07, for this period of more than four decades. The graph shows the 1998 El Nino after which the mean resumed, and again after the smaller 2010 event. The 2016 El Nino matched 1998 peak and in addition NH after effects lasted longer, followed by the NH warming 2019-20. A small upward bump in 2021 has been reversed with temps having returned again to the mean. Today we are at nearly the same temperature as 1980, with virtually no accumulation of global warming.
TLTs include mixing above the oceans and probably some influence from nearby more volatile land temps. Clearly NH and Global land temps have been dropping in a seesaw pattern, nearly 1C lower than the 2016 peak. Since the ocean has 1000 times the heat capacity as the atmosphere, that cooling is a significant driving force. TLT measures started the recent cooling later than SSTs from HadSST3, but are now showing the same pattern. It seems obvious that despite the three El Ninos, their warming has not persisted, and without them it would probably have cooled since 1995. Of course, the future has not yet been written.

News Brief by Kip Hansen – 14 April 2022
The poor Ivory-billed Woodpecker must feel like a yo-yo – being declared extinct, probably extinct and nearly maybe extinct and then being un-extincted, repeatedly over the last decade or so.
Here are some typical headlines:
“The ‘Lord God Bird’ might be extinct, but the story of the ivory-billed woodpecker isn’t over yet”
“Humans Have Officially Killed Off the Ivory-Billed Woodpecker”
“The ivory-billed woodpecker (Campephilus principalis) is a possibly extinct woodpecker”
“Is it too soon to declare the ivory-billed woodpecker extinct?”
“Ivory-billed Woodpecker to Be Officially Declared Extinct in U.S. “
And now?
Back From The Dead? Elusive Ivory-Bill Woodpecker Not Extinct: Researchers
A brand-new paper starts this way:
“The history of decline of the Ivory-billed Woodpecker is long, complex, and controversial. The last widely accepted sighting of this species in continental North America was 1944. Reports of Ivory-billed Woodpeckers have continued, yet in 2021 the U.S. Fish and Wildlife Service proposed declaring the species extinct. We draw on 10 years of search effort, and provide trail camera photos and drone videos suggesting the consistent presence of Ivory-billed Woodpeckers at our study site.”
The paper it titled “Multiple lines of evidence indicate survival of the Ivory-billed Woodpecker in Louisiana” [.pdf] and written by Steven C. Latta, Mark A. Michaels, Don Scheifler, Thomas C. Michot Peggy L. Shrume, Patricia Johnson, Jay Tischendorf, Michael Weeks, John Trochet and Bob Ford. The authors are from a diverse collection of universities and agencies. It is not the work of one disgruntled bird enthusiast.
Their findings include:
”We believe that our observations contribute to a clearer understanding of the twin problems of why the Ivory-billed Woodpecker has been so difficult to detect and to relocate over the past 80 years. These issues begin with the misperception that, if present, the Ivory-bill is relatively easy to find – a misperception that extends at least as far back as Tanner (in 1944)” or, as stated elsewhere in the paper “that the Ivory-bill should be noisy and easy to find.”
“Misperceptions on the ease of finding the Ivory-bill extend to the frequent argument that in the modern era it is unlikely that a large, distinctive woodpecker could escape the sights, cameras, and recorders, of birdwatchers and other people who are recreating or working outdoors in remote areas.”
“Beyond the questions of detection and documentation, our data offer insights into how the ecology and behavior of the Ivory-billed Woodpecker would contribute to the difficulty in finding or re-finding this species. We know that the Ivory-bill inhabits some of the most difficult to access habitat in the U.S., and that mature bottomland forests are a core component of that habitat.”
And then, as with many other subjects:
“The authenticity of reports from non-scientists, hunters, fishermen, and rural residents, who may be the most likely people to access habitats such as those occupied by the Ivory-bill, are often dismissed. Though often keen and knowledgeable observers of their natural world, their observations of rare or unusual species are frequently devalued relative to the science-based perspectives of researchers.”
As usual, the experts wouldn’t accept the practical evidence from those mostly likely to have good evidence.
Besides that, apparently Ivory-bills don’t really like people and avoid them and populated areas.
Bottom Line:
Ivory-billed Woodpeckers are not extinct – but are rare and live in limited areas of bottom-land forests far from humans. They are not booming but they are not gone.
Does it really matter? In the larger scheme of things, probably not, there are actually just a large woodpecker, a little mysterious, with a limited range.

Author’s Comment:
I have been amused by the on-again-off-again Ivory-bill story. I do like woodpeckers though. My five-year old grandson and I built this peanut feeder for his back yard and he insisted on adding the lettering . . . .
Thanks for reading.
