The warmist Met office’s latest hadCRUT4 data shows global temps are back down to 1997 levels, closely matching sat temps. Therefore the extremely inconvenient “Pause” or “Hiatus” can now be tracked for a period going on 20 years, despite *record* CO2 emissions over the same period. Not at all what we were promised by experts. The scam is over. The theory is bust.

They admit the hiatus, or pause, is still a puzzle: ‘processes remain unclear’. What is clear is that the observed temperature trend in the study period is unlike the carbon dioxide trend.
The increasing rate of the global mean surface temperature was reduced from 1998 to 2013, known as the global warming hiatus, or pause.
Researchers have devoted much effort to the understanding of the cause, reports Phys.org. The proposed mechanisms include the internal variability of the coupled ocean-atmosphere system, ocean heat uptake and redistribution, and many others.
However, scientists also want to understand the atmospheric footprint of the recent warming hiatus as the dynamical and physical processes remain unclear.

“The fact that there has been no warming for the last 18 years is a massive blow to the credibility of climate science.”
2016 tied with 1998. Therefore if all things in the climate system are equal, this would suggest that climate sensitivity to CO2 is zero! Perhaps even negative considering a third of all human emissions since 1750 have been emitted over the past 18 years – with zero warming to show.
Add to this, La Niña has not even kicked in yet. A rough 2017/18 ahead for the global warming faithful.

RSS have also now released their temperature data for December, which, as with UAH, shows a big drop from the month before.
Annually, RSS co9me to the same conclusion as UAH, that 2016 was 0.02C warmer than 1998.
As Roy Spencer has pointed out, the margin of error is 0.1C, so statistically 2016 is tied with 1998 as the warmest year in the satellite record.
The fact that there has been no warming for the last 18 years is a massive blow to the credibility of climate science.

Record Drop In Global Temperatures As El Nino Warming Ends | The Global Warming Policy Forum (GWPF)
The controversial global warming aka climate change “hiatus/pause”, lingering like a bad smell to climate alarmists for nearly two decades, is back in play with a record drop in global temperatures since the middle of the year.
Temperatures are heading south rapidly. The latest huge drop despite record and increasing CO2 emissions.
Must be nearing revision time for the theory of Catastrophic Global Warming with regards to CO2-sensitivity?

RECORD DROP IN GLOBAL TEMPERATURES AS EL NINO WARMING ENDS
Global average temperatures over land have plummeted by more than 1C since the middle of this year – their biggest and steepest fall on record. According to satellite data, the late 2016 temperatures are returning to the levels they were at after the 1998 El Nino.
The news comes amid mounting evidence that the recent run of world record high temperatures is about to end.
The fall, revealed by Nasa satellite measurements of the lower atmosphere, has been caused by the end of El Nino – the warming of surface waters in a vast area of the Pacific west of Central America.
Some scientists, including Dr Gavin Schmidt, head of Nasa’s climate division, have claimed that the recent highs were mainly the result of long-term global warming.
Others have argued that the records were caused by El Nino, a complex natural phenomenon that takes place every few years, and has nothing to do with greenhouse gas emissions by humans.
The new fall in temperatures suggests they were right.
Big El Ninos always have an immense impact on world weather, triggering higher than normal temperatures over huge swathes of the world. The 2015-16 El Nino was probably the strongest since accurate measurements began, with the water up to 3C warmer than usual.
It has now been replaced by a La Nina event – when the water in the same Pacific region turns colder than normal.
This also has worldwide impacts, driving temperatures down rather than up.
The satellite measurements over land respond quickly to El Nino and La Nina. Temperatures over the sea are also falling, but not as fast, because the sea retains heat for longer.
This means it is possible that by some yardsticks, 2016 will be declared as hot as 2015 or even slightly hotter – because El Nino did not vanish until the middle of the year.
But it is almost certain that next year, large falls will also be measured over the oceans, and by weather station thermometers on the surface of the planet – exactly as happened after the end of the last very strong El Nino in 1998. If so, some experts will be forced to eat their words.
Last year, Dr Schmidt said 2015 would have been a record hot year even without El Nino.
‘The reason why this is such a warm record year is because of the long-term underlying trend, the cumulative effect of the long-term warming trend of our Earth,’ he said. This was ‘mainly caused’ by the emission of greenhouse gases by humans.
Dr Schmidt also denied that there was any ‘pause’ or ‘hiatus’ in global warming between the 1998 and 2015 El Ninos.
But on its website home page yesterday, Nasa featured a new study which said there was a hiatus in global warming before the recent El Nino, and discussed why this was so. Last night Dr Schmidt had not returned a request for comment.
However, both his own position, and his Nasa division, may be in jeopardy. US President-elect Donald Trump is an avowed climate change sceptic, who once claimed it was a hoax invented by China.
Last week, Mr Trump’s science adviser Bob Walker said he was likely to axe Nasa’s $1.9 billion (about £1.4 billion) climate research budget.
Other experts have also disputed Dr Schmidt’s claims. Professor Judith Curry, of the Georgia Institute of Technology, and president of the Climate Forecast Applications Network, said yesterday: ‘I disagree with Gavin. The record warm years of 2015 and 2016 were primarily caused by the super El Nino.’
The slowdown in warming was, she added, real, and all the evidence suggested that since 1998, the rate of global warming has been much slower than predicted by computer models – about 1C per century.
David Whitehouse, a scientist who works with Lord Lawson’s sceptic Global Warming Policy Foundation, said the massive fall in temperatures following the end of El Nino meant the warming hiatus or slowdown may be coming back.
‘According to the satellites, the late 2016 temperatures are returning to the levels they were at after the 1998 El Nino.
The data clearly shows El Nino for what it was – a short-term weather event,’ he said.

Further analysis from Paul Homewood’s excellent site Not A Lot Of People Know That :
Rose uses satellite data for his graph, but the NOAA surface data for land also gives a stark picture:
Climate at a Glance | National Centers for Environmental Information (NCEI)
Even NOAA admit that October was by far the coldest over land since 2001, despite the fact that are we still awaiting the start of La Nina.
It is also becoming increasingly apparent that this year’s El Nino event is the strongest one at least for the last 60 years, more powerful than 1983/3 and 1997/8.
Whilst it has not peaked quite as high, it has been much more longer lasting.

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.

The two urban stations at Melbourne and Sydney both showed strong warming, and both have disastrously poor siting of their thermometers in the middle of large cities.
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.)
The only conclusion which can be derived from this is that Australia has not warmed long-term, and that BOM claims of record temperatures are due to UHI and/or data tampering.

Been hearing that 2015 was the hottest year on record? This depends entirely on which temperature data set is being referred. There are two main methods of measuring global temperature:
- The much more accurate and comprehensive satellite measurement systems, RSS/UAH, which measure the average temperature of every cubic inch of the lower atmosphere, the exact place where global warming theory is meant to occur and be measured! Or…
- NASA and NOAA’s preferred surface-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’ the 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 (doctored in square brackets by Climatism)
- The other issue with surface-based thermometer readings is that you can travel hundreds if not thousands of kilometres without finding a thermometer nearby. The Arctic region is a great example of this, as well the oceans which cover 70 percent of the planet.
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 temperature measurement systems used to measure global temperature and fundamentally to help combat misinformation about NASA and NOAA’s “Hottest Year Ever” – PR claims that tell us everything about marketing, and nothing about science…
Measuring global temperatures: Satellites or thermometers?
via CFACT
January 26, 2016 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 thermometers, 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.

Dr Roy Spencer, former senior scientist for Climate studies at NASA’s Marshall Space Flight Center, and current principal research scientist for the University of Alabama in Huntsville, reports that 2015 will not be “The Hottest Year Ever” despite a strong El Niño …. and even stronger hot-air from the climate alarm industry.
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…

UAH and RSS
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).

UPDATE
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?
Paul Homewood from NOT A LOT OF PEOPLE KNOW THAT :
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.
http://www.esrl.noaa.gov/psd/enso/mei/
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.
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.

With the ever increasing divergence of surface temperatures from satellite ones, and the subsequent divergence of overheated climate models to observed reality, it is worth a background on atmospheric measurement systems from former NASA climate scientist Dr. Roy Spencer, Ph.D. – climatologist at the University of Alabama in Huntsville who he developed the first temperature record based on satellites…

The satellite instruments measure nearly every cubic kilometer – hell, every cubic inch — of the lower atmosphere on a daily basis.

Watts Up With That?
By Christopher Monckton of Brenchley
The Christmas pantomime here in Paris is well int0 its two-week run. The Druids who had hoped that their gibbering incantations might begin to shorten the Pause during the United Necromancers’ pre-solstice prayer-group have been disappointed. Gaia has not heeded them. She continues to show no sign of the “fever” long promised by the Prophet Gore. The robust Pause continues to resist the gathering el Niño. It remains at last month’s record-setting 18 years 9 months (Fig. 1).
Figure 1. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset continues to show no global warming for 18 years 9 months since February 1997, though one-third of all anthropogenic forcings have occurred during the period of the Pause.
The modelers ought to be surprised by the persistence of the Pause. NOAA, with rare honesty, said in its 2008 State of…

The global temperature anomaly of ~0.2C is about the same as it was 30 years ago, before the eruption of El Chichon cooled temperatures 0.5C.
Another way of saying this politely, is that global warming is almost complete BS, and the people behind it are crooks.
