THERE Is No Unprecedented Global Modern Warming

“DURING 2017, there were 150 graphs from 122 scientific papers published in peer-reviewed journals indicating modern temperatures are not unprecedented, unusual, or hockey-stick-shaped —nor so they fall outside the range of natural variability…”

You have heard the wailing and screaming about President Trump’s exit from the Paris Climate Accords, but do you understand that the agreement, never ratified by the U.S. government (NOT a treaty) accomplished nothing at all to modify or change the climate. The climate of the earth has been changing mildly for millions of years, and there is no unprecedented Global-Scale modern warming. The “Accords” were designed to transfer large amounts of wealth from the rich nations to the poor nations, ostensibly to allow them to save themselves from that non-existent unprecedented warming.

There are two kinds of climate science that we are dealing with. One is based on satellite measurements and thermometer readings and recorded history. The other is based on computer programs, based, I believe on computer programs that were designed to forecast what the financial markets were going to do. They took what they knew about the…

“THE PAUSE” Lives On : Global Temperatures Continue To Cool Despite Record And Rising CO2 Emissions


GLOBAL temps continue their cooling trend, rebounding off the 2015/16 Super El Niño – the strongest since accurate measurements began, caused by surface waters in the Pacific Ocean, west of Central America rising up to 3C warmer than usual.

THE latest UAH V6.0 February anomaly of +0.20 brings temperatures back to the levels they were at after the 1998 El Niño.

UAH Feb data and results here…





NASA’s MSU satellite measurement systems, generate the RSS and UAH datasets, which measure the average temperature of every cubic inch of the lower atmosphere, the exact place where global warming theory is meant to occur.

BEFORE 2016, UAH and RSS both tracked closely showing very little warming in their data sets which led to the identification and validation of “the pause” in global warming which has since become the subject of much research and debate in peer-reviewed scientific journals.

From the RSS website:

HOWEVER, by 2016, Carl Mears, who is the chief scientist for RSS (Remote Sensing Systems) and who has used the pejorative “denialist” in various correspondence, decided that “the pause” was not a good look for the global warming narrative so RSS was massively adjusted upwards, conveniently eliminating “the pause” in the RSS dataset.

Mears’ objectivity towards the business of global temperature data collection and reporting can be found in his commentary on his website:

MEARS then published a paper claiming that new and improved adjustments have “found” that missing warming.

Christy –  Distinguished Professor of Atmospheric Science and Director of the Earth System Science Center at The University of Alabama in Huntsville. And Roy Spencer Ph.D. Principal Research Scientist at the University of Alabama in Huntsville.

Spencer commentary on the divergence between RSS and UAH post “adjustment”:

“We have a paper in peer review with extensive satellite dataset comparisons to many balloon datasets and reanalyses. These show that RSS diverges from these and from UAH, showing more warming than the other datasets between 1990 and 2002 – a key period with two older MSU sensors both of which showed signs of spurious warming not yet addressed by RSS. I suspect the next chapter in this saga is that the remaining radiosonde datasets that still do not show substantial warming will be the next to be “adjusted” upward.

The bottom line is that we still trust our methodology. But no satellite dataset is perfect, there are uncertainties in all of the adjustments, as well as legitimate differences of opinion regarding how they should be handled.

Also, as mentioned at the outset, both RSS and UAH lower tropospheric trends are considerably below the average trends from the climate models.

And that is the most important point to be made.”

GOOD READ : Satellites / Thermometers

Measuring global temperatures: Satellites or thermometers? 


by Dr. Roy Spencer

The University of Alabama in Huntsville

The official global temperature numbers are in, and NOAA and NASA have decided that 2015 was the warmest year on record. Based mostly upon surface Dr_-Roy-Spencer-178x300thermometers, the official pronouncement ignores the other two primary ways of measuring global air temperatures, satellites and radiosondes (weather balloons).

The fact that those ignored temperature datasets suggest little or no warming for about 18 years now, it is worth outlining the primary differences between these three measurement systems.

Three Ways to Measure Global Temperatures

The primary ways to monitor global average air temperatures are surface based thermometers (since the late 1800s), radiosondes (weather balloons, since about the 1950s), and satellites measuring microwave emissions (since 1979). Other technologies, such as GPS satellite based methods have limited record length and have not yet gained wide acceptance for accuracy.

While the thermometers measure near-surface temperature, the satellites and radiosondes measure the average temperature of a deep layer of the lower atmosphere. Based upon our understanding of how the atmosphere works, the deep layer temperatures are supposed to warm (and cool) somewhat more strongly than the surface temperatures. In other words, variations in global average temperature are expected to be magnified with height, say through the lowest 10 km of atmosphere. We indeed see this during warm El Nino years (like 2015) and cool La Nina years.

The satellite record is the shortest, and since most warming has occurred since the 1970s anyway we often talk about temperature trends since 1979 so that we can compare all three datasets over a common period.

Temperatures of the deep ocean, which I will not address in detail, have warmed by amounts so small — hundredths of a degree — that it is debatable whether they are accurate enough to be of much use. Sea surface temperatures, also indicating modest warming in recent decades, involve an entirely new set of problems, with rather sparse sampling by a mixture of bucket temperatures from many years ago, to newer ship engine intake temperatures, buoys, and since the early 1980s infrared satellite measurements.

How Much Warming?

Since 1979, it is generally accepted that the satellites and radiosondes measure 50% less of a warming trend than the surface thermometer data do, rather than 30-50% greater warming trend that theory predicts for warming aloft versus at the surface.

This is a substantial disagreement.

Why the Disagreement?

There are different possibilities for the disagreement:

1) Surface thermometer analyses are spuriously overestimating the true temperature trend
2) Satellites and radiosondes are spuriously underestimating the true temperature trend
3) All data are largely correct, and are telling us something new about how the climate system operates under long-term warming.

First let’s look at the fundamental basis for each measurement.

All Temperature Measurements are “Indirect”

Roughly speaking, “temperature” is a measure of the kinetic energy of motion of molecules in air.

Unfortunately, we do not have an easy way to directly measure that kinetic energy of motion.

Instead, many years ago, mercury-in-glass or alcohol-in-glass thermometers were commonly used, where the thermal expansion of a column of liquid in response to temperature was estimated by eye. These measurements have now largely been replaced with thermistors, which measure the resistance to the flow of electricity, which is also temperature-dependent.

Such measurements are just for the air immediately surrounding the thermometer, and as we all know, local sources of heat (a wall, pavement, air conditioning or heating equipment, etc.) can and do affect the measurements made by the thermometer. It has been demonstrated many times that urban locations have higher temperatures than rural locations, and such spurious heat influences are difficult to eliminate entirely, since we tend to place thermometers where people live.

Radiosondes also use a thermistor, which is usually checked against a separate thermometer just before weather balloon launch. As the weather balloon carries the thermistor up through the atmosphere, it is immune from ground-based sources of contamination, but it still has various errors due to sunlight heating and infrared cooling which are minimized through radiosonde enclosure design. Radiosondes are much fewer in number, generally making hundreds of point measurements around the world each day, rather than many thousands of measurements that thermometers make.

Satellite microwave radiometers are the fewest in number, only a dozen or so, but each one is transported by its own satellite to continuously measure virtually the entire earth each day. Each individual measurement represents the average temperature of a volume of the lower atmosphere about 50 km in diameter and about 10 km deep, which is about 25,000 cubic kilometers of air. About 20 of those measurements are made every second as the satellite travels and the instrument scans across the Earth.

The satellite measurement itself is “radiative”: the level of microwave emission by oxygen in the atmosphere is measured and compared to that from a warm calibration target on the satellite (whose temperature is monitored with several highly accurate platinum resistance thermometers), and a cold calibration view of the cosmic background radiation from space, assumed to be about 3 Kelvin (close to absolute zero temperature). A less sophisticated (infrared) radiation temperature measurement is made with the medical thermometer you place in your ear.

So, Which System is Better?

The satellites have the advantage of measuring virtually the whole Earth every day with the same instruments, which are then checked against each other. But since there are very small differences between the instruments, which can change slightly over time, adjustments must be made.

Thermometers have the advantage of being much greater in number, but with potentially large long-term spurious warming effects depending on how each thermometer’s local environment has changed with the addition of manmade objects and structures.

Virtually all thermometer measurements require adjustments of some sort, simply because with the exception of a few thermometer sites, there has not been a single, unaltered instrument measuring the same place for 30+ years without a change in its environment. When such rare thermometers were identified in a recent study of the U.S., it was found that by comparison the official U.S. warming trends were exaggerated by close to 60%. Thus, the current official NOAA adjustment procedures appear to force the good data to match the bad data, rather than the other way around. Whether such problem exist with other countries data remains to be seen.

Changes in radiosonde design and software have occurred over the years, making some adjustments necessary to the raw data.

For the satellites, orbital decay of the satellites requires an adjustment of the “lower tropospheric” (LT) temperatures, which is well understood and quite accurate, depending only upon geometry and the average rate of temperature decrease with altitude. But the orbital decay also causes the satellites to slowly drift in the time of day they observe. This “diurnal drift” adjustment is less certain. Significantly, very different procedures for this adjustment have led to almost identical results between the satellite datasets produced by UAH (The University of Alabama in Huntsville) and RSS (Remote Sensing Systems, Santa Rosa, California).

The fact that the satellites and radiosondes – two very different types of measurement system — tend to agree with each other gives us somewhat more confidence in their result that warming has been much less than predicted by climate models. But even the thermometers indicate less warming than the models, just with less of a discrepancy.

And this is probably the most important issue…that no matter which temperature monitoring method we use, the climate models that global warming policies are based upon have been, on average, warming faster than all of our temperature observation systems.

I do believe “global warming” has occurred, but (1) it is weaker than expected, based upon independent satellite and weather balloon measurements; (2) it has been overestimated with poorly adjusted surface-based thermometers; (3) it has a substantial natural component; and (4) it is likely to be more beneficial to life on Earth than harmful.

Why John Christy’s Missing Hotspot Matters

“One of the key predicted observations of anthropogenic CO2 climate theory is the existence of an equatorial tropospheric hotspot.

“But nobody has yet managed to unequivocally detect that predicted hotspot.”

IMO, one of the most important pieces of the “global warming” aka “climate change” aka “climate disruption” debate … the missing ‘Hot-Spot’.

Dr David Evans wrote an excellent piece on the missing “hot spot” back in 2008:

Watts Up With That?

One thing which struck me about the recent climate science hearing is how little attention was paid to Dr. John Christy’s demonstration of a flawed climate model prediction – the missing Tropospheric hotspot.

A flawed prediction does not automatically mean the models are totally wrong – but it is a strong indicator that something isn’t right.

Consider the primary observation. The world has warmed since the mid 1850s, and for the sake of argument lets assume that the world has warmed since the mid 1930s.

Given that warming, you could propose a number of different theories for the cause of that warming, for example;

1. Chaotic shifts in ocean currents or solar influences have influenced global temperature.
2. Anthropogenic CO2 emissions have caused global temperature to rise

Global Warming Hype.jpg

Global Warming activists routinely parrot the infamous “Hottest Year Ever” meme.

However, this depends entirely on which temperature data set is cited:

NASA’s ‘GISS’ temp uses land and ocean-based thermometers which measure “different parts of the system [UHI affected parking lots, asphalt heat sinks, AC exhaust air vents], different signal to noise ratio [we bias toward warm stations], different structural uncertainty [we ‘homogenise’ our data set to cool the past and warm the present to fit the global warming narrative].NASA GISS Gavin Schmidt’s admission about the satellite record versus the surface temperature record (square bracket add-ons by Climatism)

Then there are the much more accurate and comprehensive satellite measurement systems, RSS/UAH, which measure 24/7 the average temperature of every cubic inch of the lower troposphere – the exact place where global warming is meant to occur, according to the theory.

There is a growing divergence between NASA’s (land-based) GISS temp and RSS (lower troposphere) satellite temps since 2000:


Gavin’s New Site | Real Science

The growing divergence between NASA’s GISS and RSS satellite data sets, since 2000, didn’t used to be so stark.

So why the obvious temp divergence, post 2000, after near exact correlation from 1979?

By contrast, all of the rural stations show a long term cooling trend, with some recent warming. (Note that there is no data for the most recent years with some of the rural stations.)

Outside of how to accurately measure the earth’s atmosphere to detect the supposed anthropogenic global warming signal, there is a mountain of damning evidence relating to the fraudulent tampering of the global temperature record by climate activist government agencies – NASA and NOAA.

I highly recommend visiting Tony Heller’s site “Real Climate Science” for a comprehensive understanding of the blatant manipulation of NASA’s GISS temp data set to fit the global warming narrative.

2015 will be the 3rd Warmest Year in the Satellite Record

December 3rd, 2015

Way back in June, John Christy and I called 2015 as being the warmest year on record…in the surface thermometer data. Given the strong El Nino in progress, on top of the official thermometer data warming trend, this seemed pretty obvious.

Of course, everyone has their opinions regarding how good the thermometer temperature trends are, with periodic adjustments that almost always make the present warmer or the past colder.

But I’m not going there today…

Instead, I’m going to talk about our only truly global dataset: the satellite data. With the November 2015 data now in, it’s pretty clear that in our UAH analysis 2015 will only be the 3rd warmest year since the satellite record began in 1979. Based upon my calculations, this will be true no matter what happens in December (barring Armageddon).

Here are the yearly rankings, for which I assumed the December 2015 anomaly will be +0.40 C (click for full-size):

The years are displayed with the warmest on the left, and the coldest on the right. The color coding and arrows have to do with El Nino years…

2015 will be the 3rd Warmest Year in the Satellite Record « Roy Spencer, PhD



With the ever increasing divergence of surface temperatures (NASA GISS) from satellite ones (UAH/RSS), and the subsequent divergence of overheated climate models (IPCC CMIP5) to observed reality, it is worth some background on the atmospheric temperature measurement systems used to measure the temperature of the lower troposphere – the exact place where global warming theory is meant to occur and be measured :

Roy Spencer :

…if for no other reason than this: thermometers cannot measure global averages — only satellites can. The satellite instruments measure nearly every cubic kilometer – hell, every cubic inch — of the lower atmosphere on a daily basis. You can travel hundreds if not thousands of kilometers without finding a thermometer nearby.

The two main research groups tracking global lower-tropospheric temperatures (our UAH group, and the Remote Sensing Systems [RSS] group) show 2014 lagging significantly behind 2010 and especially 1998:


With only 3 months left in the year, there is no realistic way for 2014 to set a record in the satellite data.
Granted, the satellites are less good at sampling right near the poles, but compared to the very sparse data from the thermometer network we are in fat city coverage-wise with the satellite data.
In my opinion, though, a bigger problem than the spotty sampling of the thermometer data is the endless adjustment game applied to the thermometer data. The thermometer network is made up of a patchwork of non-research quality instruments that were never made to monitor long-term temperature changes to tenths or hundredths of a degree, and the huge data voids around the world are either ignored or in-filled with fictitious data.
Furthermore, land-based thermometers are placed where people live, and people build stuff, often replacing cooling vegetation with manmade structures that cause an artificial warming (urban heat island, UHI) effect right around the thermometer. The data adjustment processes in place cannot reliably remove the UHI effect because it can’t be distinguished from real global warming.
Satellite microwave radiometers, however, are equipped with laboratory-calibrated platinum resistance thermometers, which have demonstrated stability to thousandths of a degree over many years, and which are used to continuously calibrate the satellite instruments once every 8 seconds. The satellite measurements still have residual calibration effects that must be adjusted for, but these are usually on the order of hundredths of a degree, rather than tenths or whole degrees in the case of ground-based thermometers.
And, it is of continuing amusement to us that the global warming skeptic community now tracks the RSS satellite product rather than our UAH dataset. RSS was originally supposed to provide a quality check on our product (a worthy and necessary goal) and was heralded by the global warming alarmist community. But since RSS shows a slight cooling trend since the 1998 super El Nino, and the UAH dataset doesn’t, it is more referenced by the skeptic community now. Too funny.
In the meantime, the alarmists will continue to use the outdated, spotty, and heavily-massaged thermometer data to support their case. For a group that trumpets the high-tech climate modeling effort used to guide energy policy — models which have failed to forecast (or even hindcast!) the lack of warming in recent years — they sure do cling bitterly to whatever will support their case.
As British economist Ronald Coase once said, “If you torture the data long enough, it will confess to anything.”
So, why are the surface thermometer data used to the exclusion of our best technology — satellites — when tracking global temperatures? Because they better support the narrative of a dangerously warming planet.
Except, as the public can tell, the changes in global temperature aren’t even on their radar screen (sorry for the metaphor).

Why 2014 Won’t Be the Warmest Year on Record « Roy Spencer, PhD



The temperature divergence, this century, between NASA GISS temp (land based) and RSS satellite data, is mind-blowing.

Looks like someone is adjusting the curve to fit the ‘global warming’ narrative. Gavin? Tom?

Between 1979 and 2001, the RSS satellite data increased at virtually the same rate as GISS. Since then, there has been a massive divergence, with GISS claiming that the pace of increase has barely reduced from the earlier period.

In contrast RSS (and also UAH) confirm that, if anything, temperatures have been dropping.

RSS figures for November are now out, and also show a small fall on October, as did UAH. The 12-month running average still refuses to go above earlier years, despite the strongest El Nino conditions since 1998.


Although temperatures are likely to rise still further in the next few months, there is absolutely no way this year will come close to approaching either 1998 or even 2010.
