GLOBAL TEMPERATURE PLUNGE : Coolest September In The Last 10 Years


We’ve got to ride this global warming issue.
Even if the theory of global warming is wrong,
we will be doing the right thing in terms of
economic and environmental policy.

GLOBAL atmospheric temperatures continue their rapid decline off the record heights of the 2016 super El Niño, despite record and rising CO2 emissions.

UAH global average lower tropospheric temperature (LT) anomaly for September, 2018 was +0.14°C, down from +0.19°C in August:

Latest Global Average Tropospheric Temperatures

Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. The intensity of the signals these microwave radiometers measure at different microwave frequencies is directly proportional to the temperature of different, deep layers of the atmosphere. Every month, John Christy and I update global temperature datasets that represent the piecing together of the temperature data from a total of fifteen instruments flying on different satellites over the years. A discussion of the latest version (6.0) of the dataset is located here.

The graph above represents the latest update; updates are usually made within the first week of every month. Contrary to some reports, the satellite measurements are not calibrated in any way with the global surface-based thermometer records of temperature. They instead use their own on-board precision redundant platinum resistance thermometers (PRTs) calibrated to a laboratory reference standard before launch.

THE September anomaly represents a 0.72°C drop since 2016 super El Niño heights, bringing temps down now to ~1988 levels.

DON’T expect the mainstream media to report in this anytime soon. They are only concerned about hot and climbing temperatures to push their  global warming climate change agenda.

SATELLITES

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:

“The simulation as a whole are predicting too much warming” – RSS

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.

UAH is the satellite data set featured in this post and is jointly run by Dr. John R. 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.”

Stunning Drop In Global Temperatures As El Niño Warming Ends

Record Drop In Global Temperatures As El Nino Warming Ends | The Global Warming Policy Forum (GWPF)

 

The controversial global warming aka climate changehiatus/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

  • Date: 27/11/16
  • David Rose, Mail on Sunday

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.

NASA and NOAA will be tweaking their heads and data-sets overtime in order to declare 2016 as “The Hottest Year Evah”. Possibly too late in the year to wipe out this years “Super El niño”.

UPDATE

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.
