Tokyo Midsummer Hasn’t Warmed In Decades. And: The Missing Hurricanes”.

by Kyrie, Aug 3, 2022 in NoTricksZone

Continuously increasing CO2 emissions into the atmosphere from the burning of fossil fuels is supposed to be causing warming all over the globe right now, so we should be seeing it in most of the trends.

But often we don’t. The globe, in fact, has cooled somewhat since the El Nino of 2015/16. The media refuse to report that.

One example of no warming is the midsummer mean for Tokyo and its rural Hachijojima island in the Pacific.


Looking at the July mean temperature trend for Tokyo itself, using data from the Japan Meteorological Agency (JMA), and not the adjusted datasets from NASA, we have the following:

New Study: 96% Of U.S. Climate Data Is Corrupted

by Heartland Institute, July 28, 2022  in ClimaterChangeDispatch

A new study, Corrupted Climate Stations: The Official U.S. Surface Temperature Record Remains Fatally Flawed, finds approximately 96 percent of U.S. temperature stations used to measure climate change fail to meet what the National Oceanic and Atmospheric Administration (NOAA) considers to be “acceptable” and uncorrupted placement by its own published standards. [bold, links added]

The report, published by The Heartland Institute, was compiled via satellite and in-person survey visits to NOAA weather stations that contribute to the “official” land temperature data in the United States.

The research shows that 96% of these stations are corrupted by localized effects of urbanization – producing heat bias because of their close proximity to asphalt, machinery, and other heat-producing, heat-trapping, or heat-accentuating objects.

Placing temperature stations in such locations violates NOAA’s own published standards (see section 3.1 at this link) and strongly undermines the legitimacy and the magnitude of the official consensus on long-term climate warming trends in the United States.

“With a 96 percent warm bias in U.S. temperature measurements, it is impossible to use any statistical methods to derive an accurate climate trend for the U.S.,” said Heartland Institute Senior Fellow Anthony Watts, the director of the study.

Lennart Bengtsson: Global climate change and its relevance for a global energy policy.

by H. von Storch, March 12, 2013 in DieKlimazwiebel

The relation between temperature and greenhouse gases in its very simplistic form has been known since the second half of the 19thcentury. The effect of the greenhouse gases can be seen as a warm overcoat preventing the surface in radiating away the heat to space. However, the warming is a complex process incorporating the dynamics of atmospheric and ocean flows and interactions of the many components of what is now called the Earth’s system. This includes in addition to the atmosphere, the oceans, the land surfaces and the land ices. Its study requires advanced computer models and other tools for its analysis and understanding.  It also requires accurate observations for validation and monitoring as well as special measurements for the development of many crucial aspects of the models. It is in fact an immensely complex undertaking that is virtually impossible to explain to the public in a readily understandable way. This has lead to a tendency towards oversimplification that has contributed more to confusion than to a thorough understanding. However, because of the strong public interest we are now facing a dilemma as the public and the political community have become too much involved in the climate change debate influencing the actual science and this not necessarily in a positive way as it implies an arbitrary selection of priorities and preferential issues.


Natural processes drive climate and practically all kinds of extreme weather have always been part of the climate and are practically unrelated to the modest warming we so far have had. The effect of increasing greenhouse gases is a slow but relentless process that will have to be dealt with but will require more time and better insight in key processes.Some events are seen as very dramatic as the reduced Arctic summer ice, others, even more puzzling, such as the surprising lack of warming in the tropical troposphere is hardly discussed.

The problem is that the global warming is mainly caused by the emission of carbon dioxide and thus directly related to energy production by fossil fuels that has dominated and still dominates the energy production by more than 80%. To significantly reduce or eliminate fossil fuel is not feasible on a time-scale shorter than several decades, as it requires fundamental technical breakthrough in energy generation or alternatively a major change in our life stile. As the second alternative is hardly possible to achieve in a world with mostly open societies, it is obvious that the world community is facing a gigantic challenge. Additionally many parts of the world are suffering because of a lack of suitable energy and the need is further underpinned by the fact that the world’s population will increase by another two billion humans in the next three decades.

Some comments on the present situation

New Study Affirms Temperatures Determine Greenhouse Gas Forcing Trends, Not The Other Way Around

by Singh H  & Polvani L, Jun 30, 2022 in NoTricksZone

CO2 and water vapor greenhouse effect impacts are not independent climate forcings . A new study affirms the “variance in the radiance in these channels is primarily controlled by…temperature” and “atmospheric absorption is strongly saturated in these [CO2, water vapor] channels”.

It has previously been established that greenhouse gas (water vapor, CO2) forcing “cannot be considered an independent component of the surface energy budget” because “anomalies in the downward longwave flux at the surface primarily arise as a consequence of surface temperature anomalies, rather than being the cause of those anomalies” (Singh and Polvani, 2020, Zeppetello et al., 2019).

Image Source: Singh and Polvani, 2020, Zeppetello et al., 2019

Feldman et al. (2015) admit they had to “construct” model-based spectra to simulate a CO2 signal in their seminal paper purporting to show CO2 changes cause temperature changes. This is because the temperature and water vapor levels primarily determine the overall longwave forcing (clear-sky) trends.

New Study Suggests The Early Holocene’s Baltic Sea Temperatures Were 5-11°C Warmer Than Present

by Weiss et al., 2022 in NoTricksZone

Baltic Sea surface temperatures may have reached 24°C 7,200 years ago compared to the current 12.7°C.

A new study (Weiss et al., 2022) indicates Baltic Sea regional surface temperatures ranged between 21-24°C from ~5.7 to 7.7 ka (thousand years ago). This period is referred to as the Baltic’s Holocene Thermal Maximum.

Temperatures dipped to 17.2°C at 1.373 ka. (The time span ranging from 0.0 ka to 3 ka is referred to in the study as the Modern Baltic, or M.B.)

The current (0.0 ka) surface temperature for the Baltic S is 12.7°C. This temperature is more than 11°C colder than the Baltic’s temperatures at 7.2 ka.

Evidence that Clouds Actively Regulate the Temperature

by W. Eschenbach, Oct 6, 2013 in WUWT

I have put forth the idea for some time now that one of the main climate thermoregulatory mechanisms is a temperature-controlled sharp increase in albedo in the tropical regions. I have explained that this occurs in a stepwise fashion when cumulus clouds first emerge, and that the albedo is further increased when some of the cumulus clouds evolve into thunderstorms.

I’ve demonstrated this with actual observations in a couple of ways. I first showed it by means of average photographs of the “view from the sun” here. I’ve also shown this occurring on a daily basis in the TAO data. So I thought, I should look in the CERES data for evidence of this putative phenomenon that I claim occurs, whereby the albedo is actively controlling the thermal input to the climate system.

Mostly, this thermoregulation appears to be happening over the ocean. And I generally dislike averages, I avoid them when I can.  So … I had the idea of making a scatterplot of the total amount of reflected solar energy, versus the sea surface temperature, on a gridcell-by-gridcell basis. No averaging required. I thought well, if I’m correct, I should see the increased reflection of solar energy required by my hypothesis in the scatterplots. Figure 1 shows those results for four individual months in one meteorological year. (The year-to-year variations are surprisingly small, so these months are quite representative.)

Climate Change in the Early Holocene

Radiocarbon dating from a prehistoric cemetery in Northern Russia reveals human stress caused by a global cooling event 8,200 years ago Early hunter gatherers developed more complex social systems and, unusually, a large cemetery when faced by climate

Peer-Reviewed Publication

Climate change in the Early Holocene

  • Radiocarbon dating from a prehistoric cemetery in Northern Russia reveals human stress caused by a global cooling event 8,200 years ago
  • Early hunter gatherers developed more complex social systems and, unusually, a large cemetery when faced by climate change

New insight into how our early ancestors dealt with major shifts in climate is revealed in research,  published today [27 Jan] in Nature Ecology & Evolution, by an international team, led by Professor Rick Schulting from Oxford University’s School of Archaeology.

It reveals, new radiocarbon dates show the large Early Holocene cemetery of Yuzhniy Oleniy Ostrov, at Lake Onega, some 500 miles north of Moscow, previously thought to have been in use for many centuries, was, in fact, used for only one to two centuries. Moreover, this seems to be in response to a period of climate stress.

105 More Non-Global Warming/Non-Hockey Stick Temperature Records Added To The Database In 2021

by K. Richard, Jan 31, 2022 in NoTricksZone

Since 2019,there have been over 350 peer-reviewed scientific papers published showing no warming in the modern era and/or much warmer temperatures than today when CO2 levels ranged from 180 to 280 ppm (Holocene, Pleistocene).

Below is the link to the updated (now including 2021) database of non-hockey temperature records from locations across the world.

These hundreds of papers suggest a) Earth was multiple degrees warmer than today throughout much of the last 11,700 years (Holocene), and b) there has been nothing unusual about temperature changes in the modern era.

The first 8 papers on the 2021 list are shown below as samples.

Using A Reference Period Outdated 30 Years, Germany’s DWD Weather Service Turns Cooling Into Warming

by Prof. F. Vahrenholt, Jan 8, 2022 in NoTricksZone

Globally, the deviation of the global mean temperature of the satellite-based measurements from the mean of period 1991-2020 rose slightly in December to 0.21 degrees Celsius. The mean temperature increase since satellite measurements began was 0.14 degrees Celsius per decade. The year 2021 was an average year compared to 2010 to 2020, with 0.134 degrees deviation from the thirty-year average. Six years since 2010 were warmer and 5 years were colder.

This is also true for Germany. But the German weather service gives a different impression

How the German DWD Weather Service turned cooling into warming in 2021  

In its press release on Germany’s weather in 2021, the German Weather Service writes: “The mean temperature [Germany] in 2021 was 9.1 degrees Celsius (°C), 0.9 degrees above the value of the internationally valid reference period 1961 to 1990. 2021 was thus the eleventh year in a row that was too warm.”

Why does the DWD use the internationally no longer valid 1961-1990 reference period? It writes itself elsewhere: “To record the climate and its changes, mean values are formed over a period of 30 years…With the end of the year 2020, the reference period for current climatological assessments was replaced by the 1991 to 2020 period.”

Fudging with the reference period

The DWD thus followed the World Meteorological Organization (WMO)recommendation. But in the press release, the DWD still prefers to use the old, outdated period. The 1991 to 202 0reference period differs from the one of 1961 to 1990 by 1.1 degrees. So the DWD should have written : “2021 was 9.1 degrees, 1.3 degrees cooler than 2020 and even -0.2 degrees Celsius below the average from 1991 to 2020. Since 1991 there have only been 9 years colder than 2021.”

But 0.9 degrees more and the eleventh year in a row that is too warm (compared to the colder period of 1961-1990) of course fits much better with the zeitgeist.

Autocorrelation in CO2 and Temperature Time Series

by A. May, Nov 14, 2021 in WUWT

In my last post I plotted the NASA CO2 and the HadCRUT5 records from 1850 to 2020 and compared them. This was in response to a plot posted on twitter by Robert Rohde implying they correlated well. The two records appear to correlate because the resulting R2 is 0.87. The least square’s function used made the global temperature anomaly a function of the logarithm to the base 2 of the CO2 concentration (or ‘log2CO2‘). This means the temperature change was assumed to be linear with the doubling of the CO2concentration, a common assumption. The least squares (or ‘LS’) methodology assumes there is no error in the measurements of the CO2 concentration and all error resulting from the correlation (the residuals) resides in the HadCRUT5 global average surface temperature estimates.

In the comments to the previous post, it became clear that some readers understood the computed R2(often called the coefficient of determination), from LS, was artificially inflated because both X (log2CO2) and Y (HadCRUT5) were autocorrelated and increased with time. But a few did not understand this vital point. As most investors, engineers, and geoscientists know, two time series that are both autocorrelated and increase with time will almost always have an inflated R2. This is one type of “spurious correlation.” In other words, the high R2 does not necessarily mean the variables are related to one another. Autocorrelation is a big deal in time series analysis and in climate science, but too frequently ignored. To judge any correlation between CO2 and HadCRUT5 we must look for autocorrelation effects. The most tool used is the Durbin-Watson statistic.

The Durbin-Watson statistic tests the null hypothesis that the residuals from a LS regression are not autocorrelated against the alternative that they are. The statistic is a number between 0 and 4, a value of 2 indicates non-autocorrelation and a value < 2 suggests positive autocorrelation and a value >2 suggests negative autocorrelation. Since the computation of R2 assumes that each observation is independent of the others, we hope that we get a value of 2, that way the R2 is valid. If the regression residuals are autocorrelated and not random—that is normally distributed about the mean—the R2 is invalid and too high. In the statistical program R, this is done—using a linear fit—with only one statement, as shown below:

CO2 and Temperature

by A. May, Nov 9, 2021 in WUWT

I had a very interesting online discussion about CO2 and temperature with Tinus Pulles, a retired Dutch environmental scientist. To read the whole discussion, go to the comments at the end of this post. He presented me with a graphic from Dr. Robert Rohde from twitter that you can find here. It is also plotted below, as Figure 1.


I’m not impressed with Rohde’s display. The coefficient of correlation is decent, but it does not show that warming is controlled by changes in CO2, the temperature reversals are not explained. The reversals strongly suggest that natural forces are playing a significant role in the warming and can reverse the influence of CO2. The plots show that, at most, CO2 explains about 50% of the warming, something else, like solar changes, must be causing the reversals. If they can reverse the CO2-based warming and overwhelm the influence of CO2 they are just as strong.

The climate moaners need to get some perspective from history

by Ian Plimmer, Nov 4, 2021, SpectatorAustralia

Greta Thunberg rejects all ideas of the enlightenment. Despite what she wails, she is now living in the best times ever to be a child on planet Earth. She can actually go to FLOP26, something that few of us would want to do. Would she prefer to live in the worst of times when there was panic, suffering, environmental damage, death and no hope which she claims exists today?  

We now eat better, are less affected by natural disasters and are able to cope with extremes of weather and climate. During the last 4 of at least 20,000 generations of humans, child mortality has decreased and global human longevity increased from 25 to 79 years. The climate moaners need to get some perspective from history. 

The worst years to live since the time of Jesus were 535-550 AD because massive volcanic eruptions, perhaps Kamchatka or Alaska in 535-536 AD and Ilopango in El Salvador from 539-540 AD. The Northern Hemisphere atmosphere with filled with dust and acid sulphate clouds. These volcanic eruptions were coincidental with extraterrestrial impacts in March 536 AD in the Gulf of Carpentaria and elsewhere in August 536 AD. To make matters worse, these were at the time of a Solar Minimum. 

The Sun was dimmed for 18 months, a white sulphuric acid aerosol cloud enveloped Europe, global temperature dropped by 1.5 to 2.5°C producing worldwide crop failures and death by starvation. There was migration (e.g. Slavic speaking people), political turmoil and the collapse of empires (e.g. Sasanian Empire in Persia). Tree rings show almost no growth for a few years.

Aussie Met Bureau – making up 13 years of missing temperature data

by D. Mason-Jones, Oct 15, 2021 in WUWT

Upon finding a 13-year gap in its data for an important weather station in Queensland, the Australian Bureau of Meteorology homogenised data from 10 other locations to fill-in the missing years. One of these places was more than 400km away and another almost 2.5 degrees of latitude further South.

Is the resulting data credible? No, is the conclusion reached in a research Report by Australian scientist, Dr. Bill Johnston.

When the US Army Air Force (USAAF) closed its heavy bomber transit base at Charleville at the end of the Second World War the aerodrome reverted to civilian status. The base had been a link in the ferry route delivering aircraft from factories in the US to the war zone.


AR6 and The Paleocene-Eocene Thermal Maximum

by Andy May, Aug 18, 2021 in WUWT

The PETM or Paleocene-Eocene Thermal Maximum was a warm period that began between 56.3 and 55.9 Ma (million years ago). The IPCC AR6 report (actually a draft, not a final edited report), released to the public on August 9, 2021, suggests that this warm period is similar to what is happening today and they expect to happen in the future (IPCC, 2021, pp. 2-82 & 5-14). During the PETM, it was very warm and average global surface temperatures probably peaked between 25.5°C and 26°C briefly, compared to a global surface temperature average of about 14.5°C today, as shown in Figure 1.



oday we have tens of thousands of daily temperature measurements around the world and can calculate a fairly accurate global average surface temperature. To construct a global average for the PETM we must rely on proxy temperatures, such as oxygen isotope ratios, Calcium/Magnesium ratios in fossil shells, and fossil membrane lipids that are sensitive to temperature like Tex86. Proxy temperature values are sparsely located and have a temporal resolution, 56 Ma, of thousands to hundreds of thousands of years. Thus, in terms of rate of temperature change, they are not comparable to today’s monthly global averages.

Before diving into the PETM, we will provide some geological perspective. According to Christopher Scotese, the highest global average temperature in the Phanerozoic (the age of complex shelled organisms, or the past 550 million years) was the Triassic hothouse event, following the end of the Karoo Ice Age, around 250-300 Ma. Global average surface temperatures peaked then at about 27.9°C.


Is The Earth Actually Getting Hotter?

by V. Jayaraj, Aug 2, 2021 in ClimateChangeDispatch

Every year, climate-change enthusiasts tell us the earth is getting hotter. warned the world, “New ‘hottest year on record’ likely to occur in the next five years.”

C2ES informed readers, “It’s certain: The Earth is getting warmer, and human activity is largely to blame.” Bulletin of the Atomic Scientists’ headline read, “Broken record: The planet is getting hotter. And hotter. And hotter.”

But are we really observing record hot years consecutively?

While global warming is real and has been happening since the end of the Little Ice Age in the 18th century, the claims surrounding unprecedented temperatures are, at best, highly dubious.

Reality and some climate change claims differ as much as day and night. Here are two examples.

Strange Things: Readjusted Data Points

A few official agencies across the globe are widely considered “leaders” or “authoritative” in disseminating climate data.

Among them is the Met Office in the UK and top U.S. state agencies like the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA).

However, these agencies have used their near-invincible status to adjust climate data points as they please, often resulting in an exaggerated warming trend.

NASA has been found to have adjusted past temperature data downward to make the present temperature levels look comparatively warmer.

In July 2021, geologist Roger Higgs demonstrated how NASA lowered the 2016 data point for annual global mean temperature.

NASA carried out the supposed downward shifting of data points so that the temperature levels for 2020 (which were about the same as 2016) would now appear more extreme. Higgs revealed the downward shifting on Researchgate.

Why did NASA adjust the 2016 data point to make it appear that 2020 beat it by a larger margin than originally appeared? You decide.

New Study: A ‘Profound’ ~1°C Cooling Trend Across East Antarctica Since 1979 Is ‘Likely To Accelerate’

by K. Richard, July 12, 2021 in NoTricksZone

Except for a few pockets of warming along the West Antarctic coast, surface air temperatures have cooled profoundly across East Antarctica – most of the continent, as well as the surrounding Southern Ocean – in the last 40 years (1979-2018). About 30% of the cooling can be explained by Madden-Julian Oscillation forcing.

Atmospheric CO2 concentrations rose from 337 ppm in 1979 to 408 ppm in 2018.

But according to graphical illustrations of surface air temperature (SAT) trends from satellite observations documented in a new study (Hsu et al., 2021), nearly the entire continent of Antarctica and much of the surrounding Southern Ocean have undergone about -0.02°C/year (-0.2°C per decade) SAT cooling during this period.

East Antarctica’s temperatures have fallen by about 1°C in the last 40 years, with approximately -0.4°C cooling from 1999-2018 relative to 1979-1998.

Per the authors, one-third of this 40-year cooling trend can be attributed to Madden-Julian Oscillation (MJO) forcing. The MJO influence is “likely to accelerate” the long-term cooling trend for East Antarctica in the coming decades.

Record heat has been felt across the the Pacific Northwest this week, which has led the MSM and their placard-brandishing, sandal wearing EOTW groupies to draw the connection to ‘global warming’ aka ‘the climate crisis’ aka ‘terrifying terra firma broiling’.

However, AccuWeather Meteorologist Joe Lundberg is on the record as saying that AGW isn’t to blame here.

Risking a backlash from his bosses, and from those faceless elites on high, Lundberg very reasonably states: “I just think that right now we’re seeing a very unusual pattern across most of the northern hemisphere where there’s a lot of extremes.”

Lunberg sees erratic jet streams as the main culprit here, which, as Electroverse has been saying for years, are weakening due to historically low solar activity — and while Lunberg doesn’t touch on solar output, he does reference a “big upper level trough that’s in the Aleutians”.

Right now, weather patterns across the country are very unusual, explains Lundberg: “Downstream, there’s a massive upper level ridge that’s in the Northwest, that’s why they’re seeing the record heat there.

“And then downstream along the eastern seaboard, we’re also seeing another upper level ridge.

“But not everyone’s getting this heat,” adds Lundberg — far from it, “across the deep south, for example, it’s actually cooler than average and looks like its gonna stay that way for the foreseeable future.”

Latest GFS runs see temperature departures some 16-20C below the seasonal average across vast regions, particularly in New Mexico:

Antarctica wasn’t quite as cold during the last ice age as previously thought


CORVALLIS, Ore. – A study of two methods for reconstructing ancient temperatures has given climate researchers a better understanding of just how cold it was in Antarctica during the last ice age around 20,000 years ago.

Antarctica, the coldest place on Earth today, was even colder during the last ice age. For decades, the leading science suggested ice age temperatures in Antarctica were on average about 9 degrees Celsius cooler than at present.

An international team of scientists, led by Oregon State University’s Christo Buizert, has found that while parts of Antarctica were as cold as 10 degrees below current temperatures, temperatures over central East Antarctica were only 4 to 5 degrees cooler, about half of the previous estimates.

The findings were published this week in Science.

“This is the first conclusive and consistent answer we have for all of Antarctica,” said Buizert, an Oregon State University climate change specialist. “The surprising finding is that the amount of cooling is very different depending on where you are in Antarctica. This pattern of cooling is likely due to changes in the ice sheet elevation that happened between the ice age and today.”

Understanding the planet’s temperature during the last ice age is critical to understanding the transition from a cold to a warm climate and to modeling what might occur as the planet warms as a result of climate change today, said Ed Brook, a paleoclimatologist at OSU and one of the paper’s co-authors.

Total Precipitable Water & Level of Free Convection


The Greenhouse Effect In A Water World

by B. Irvine, May 17, 2021 in WUWT

A knowledge of Greenhouse gases is fundamental to any understanding of global surface temperatures. The presence of GHGs in our atmosphere has increased the global surface temperature by about 33C.

There are multiple lines of evidence, however, that challenge the strong water vapour feedback to a small initial CO2 forcing.  These strong positive feedbacks are central to the IPCC narrative.

These lines of evidence include.

  • The failure of all models and catastrophic warming projections.
  • The stubborn refusal of atmospheric Precipitable Water Vapour (PWV) concentration to rise in recent years.
  • The strength of convection cells in the tropics that have kept tropical temperatures approximately the same for many millions of years.
  • Irrigation and extra humidity generally coincide with cooler temperatures.
  • The hot spot as a signature of the positive Water Vapour (WV) feedback and its opposite, the negative lapse rate feedback, has not occurred.


Oceanic Warming? Well, sorta.

by W. Eschenbach, May 1, 2021 in WUWT

After my last post about the surface warming of the ocean, entitled “How Global Warming Isn’t“, I got to thinking about the warming of the upper part of the ocean. So I got the data for the ocean heat content (OHC) of the top 700 metres of the ocean from the marvelous site, KNMI. If you look under “Monthly Observations” you’ll find a host of most fascinating datasets. Under “Heat Content” on that page, you’ll find the National Oceanic Data Center (NODC) 0-700 metre depth OHC data. And down at the very bottom of that page is a link that will download a 196 megabyte gridded NetCDF file containing the data that I used. (Big file, click at your own risk.)

And what did I find? Well, I’m a visual kind of guy. I mean, I can do the math, but it only makes sense when it comes up as a picture on the silver screen. So here are my graphics. I’m interested in the changes in the oceanic heat content, so these are two views of those trends.

This is the bottom line. If the world’s creatures, both on land and at sea, were as temperature-sensitive as the alarmists would have us believe, those beings (and we humanoids as well) all would have gone extinct long ago. And near as I can tell, that hasn’t occurred … at least yet.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for March, 2021 has come in at -0.01 deg. C below the 30-year baseline, down from the February, 2021 value of +0.20 deg. C, and down substantially (approx. 0.6C deg. C) from where we were around a year ago.

A continuation of this downward plunge is highly probable over the coming months (with the odd bump along the way–climate is cyclic after all) as low solar activity and La Nina conditions persist.

According to the 15x NASA/NOAA AMSU satellites that measure every square inch of the lower troposphere (where us humans reside), planet Earth was actually warmer back in 1983:

REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends.

In addition, the global average oceanic tropospheric temperature anomaly is -0.07 deg. C–the lowest since November 2013. Also, the tropical (20N-20S) departure from average is -0.29 deg. C–the coolest since June of 2012. While Australia, at -0.79 deg. C, is the coolest reading since August 2014.

Bottom line, the Grand Solar Minimum is intensifying — and fast.

Sunspots (a great barometer for solar activity) have remained sparse in 2021, even at a time when the next the next solar cycle (25) should be firing-up.

The Solar Minimum of cycle 24 began bottoming-out way back in late-2017, and went on to develop into the deepest minimum of the past 100+ years — and it is still proving reluctant to release its grip:

Michael Mann “Hockey Stick” Update: Now Definitively Established To Be Fraud

by F. Menton, Aug 26, 2021 in ManhattanContrarian

The Michael Mann “Hockey Stick” is suddenly back in the news. It’s been so long since we have heard from it, do you even remember what it is?

The “Hockey Stick” is the graph that took the world of climate science by storm back in 1998. That’s when Mann and co-authors Raymond Bradley and Malcolm Hughes published in Nature their seminal paper “Global-scale temperature patterns and climate forcing over the past six centuries.” A subsequent 1999 update by the same authors, also in Nature (“Northern Hemisphere Temperatures During the Past Millennium: Inferences, Uncertainties, and Limitations”) extended their reconstructions of “temperature patterns and climate forcing” back another 400 years to about the year 1000. The authors claimed (in the first paragraph of the 1998 article) to “take a new statistical approach to reconstructing global patterns of annual temperature . . . , based on the calibration of multiproxy data networks by the dominant patterns of temperature variability in the instrumental record.” The claimed “new statistical approach,” when applied to a group of temperature “proxies” that included tree ring samples and lake bed sediments, yielded a graph — quickly labeled the “Hockey Stick” — that was the perfect icon to sell global warming fear to the public. The graph showed world temperatures essentially flat or slightly declining for 900+ years (the shaft of the hockey stick), and then shooting up dramatically during the 20th century era of human carbon dioxide emissions (the blade of the stick).

UAH Global Temperature Update for February 2021: +0.20 deg. C

by Roy Spencer, March. 3rd, 2021 in Global Warming

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for February, 2021 was +0.20 deg. C, up from the January, 2021 value of +0.12 deg. C.

REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends.

The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

Various regional LT departures from the 30-year (1991-2020) average for the last 14 months are:
