Homogenization of temperature data makes Capetown South Africa have a warmer climate record

Australia’s warmist agency BoM (Bureau of meteorology) removed the very warm temps of the late 1800’s and begins Australia’s temp record at 1910. This correlates with warm Cape Town (Southern Hemisphere) temp data, pre-1909, removed by NASA to maximise upward trend in temps, promoting the “man-made” global warming narrative.

BoM also smoothed out (removed) 1940-1970’s cooling in many regions of AUS, as seen in the Cape Town record, to create an overall warming trend.

“Man-Made” global warming, by pen and *not* CO2, indeed.

Watts Up With That?

Playing around with my hometown data, I was horrified when I found what NASA had done to it.  Even producing GISTEMP Ver 2 was counterfactual.

The raw data that is fed to NASA in order to develop the global temperature series is subjected to “homogenization” to ensure that it does not suffer from such things as the changes in the method of measuring the mean temperature, or changes in readings because of changes in location. However, while the process is supposed to be supported by metadata – i.e. the homogenizers are supposed to provide the basis for any modification of the raw data.

For example, the raw data for my home city, Cape Town, goes back to 1880:

RSS Confirm 2016 Is Tied With 1998 As Warmest Year

“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.

Alt-science climate activists

“It’s the flavor of the season: how outraged you manage to be is proof how wrong/evil your opponent is.”

“The same establishment makes a deafening racket every time there is an El Niño. In fact, climate activists actively hope for El Niño warm periods so they can hyperventilate about ‘record temperatures’ and advance their policy goals.”

Spot-on Shub.

Excellent post demonstrating the vicious rage emanating from climate change alarmists following the recent *record* drop in global temperatures!

As usual, the Left using the 101 tactic of – “Playing the man (Breitbart/Dellers), rather than the ball (evidence)”.

This is more evidence for mine that “Global Warming” aka “Climate Change” is the ultimate social(ist) issue that plays to many of the Left’s elitist agendas – power, control, money, virtue and misanthropy. After all, shouldn’t “Global Warming” alarmists be celebrating and cheering the *record* drop in global temps?! (albeit expected after a super El Niño).

Rather telling.

German Professor : NASA Has Fiddled Climate Data On ‘Unbelievable’ Scale

Brietbart’s James Delingpole confirming what sceptics have been observing with disgust for years and what thankfully the world is now becoming increasingly clear about – that NASA, under the directorship of climate change activist Gavin Schmidt and before him James Hansen (pictured) arrested 4 times for climate activism, is scandalously tampering with one of the four major global temperature data sets – GISS.

This is the same data set used by much of the climate science cabal, agenda-driven politicians and the alarmist mainstream media to claim the “Hottest Year Ever” meme.

by JAMES DELINGPOLE24 Nov 2015

A German professor has confirmed what skeptics from Britain to the US have long suspected: that NASA’s Goddard Institute of Space Studies has largely invented “global warming” by tampering with the raw temperature data records.

Professor Dr. Friedrich Karl Ewert is a retired geologist and data computation expert. He has painstakingly examined and tabulated all NASA GISS’s temperature data series, taken from 1153 stations and going back to 1881. His conclusion: that if you look at the raw data, as opposed to NASA’s revisions, you’ll find that since 1940 the planet has been cooling, not warming.

According to Günter Ederer, the German journalist who has reported on Ewert’s findings:

From the publicly available data, Ewert made an unbelievable discovery: Between the years 2010 and 2012 the data measured since 1881 were altered so that they showed a significant warming, especially after 1950. […] A comparison of the data from 2010 with the data of 2012 shows that NASA-GISS had altered its own datasets so that especially after WWII a clear warming appears – although it never existed.

Apart from Australia, the planet has in fact been on a cooling trend:

Using the NASA data from 2010 the surface temperature globally from 1940 until today has fallen by 1.110°C, and since 2000 it has fallen 0.4223°C […]. The cooling has hit every continent except for Australia, which warmed by 0.6339°C since 2000. The figures for Europe: From 1940 to 2010, using the data from 2010, there was a cooling of 0.5465°C and a cooling of 0.3739°C since 2000.

But the activist scientists at NASA GISS – initially led by James Hansen (pictured above), later by Gavin Schmidt – wanted the records they are in charge of maintaining to show warming not cooling, so they began systematically adjusting the data for various spurious reasons using ten different methods.

The most commonly used ones were:

• Reducing the annual mean in the early phase.
• Reducing the high values in the first warming phase.
• Increasing individual values during the second warming phase.
• Suppression of the second cooling phase starting in 1995.
• Shortening the early decades of the datasets.
• With the long-term datasets, even the first century was shortened.

Ewert’s findings echo that of US meteorologists Joseph D’Aleo and Anthony Watts who examined 6,000 NASA weather stations and found a host of irregularities both with the way they were sited and how the raw data had been adjusted to reflect such influences as the Urban Heat Island effect.

Britain’s Paul Homewood is also on NASA GISS’s case. Here he shows the shocking extent of the adjustments they have made to a temperature record in Brazil which has been altered so that a cooling trend becomes a warming trend.

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:

noaa-temps

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.

Characterizing the urban temperature trend using seasonal unit root analysis: Hong Kong from 1970 to 2015

Scientists from Macao Polytechnic Institute are pioneers in exploring urban temperature in Hong Kong using seasonal econometric models. In particular, the characterization of the urban temperature trend was investigated using a seasonal unit root analysis of monthly mean air temperature data over the period of January 1970 to December 2013.

“The seasonal unit root test makes it possible to determine the stochastic trend of monthly temperatures using an autoregressive model,” says Prof. Wai Ming To. “We found that Hong Kong’s urban mean air temperature has increased by 0.169°C per 10 years over the past four decades using monthly temperature data, or 0.174°C per 10 years using annual temperature data, and…

Virtually indistinguishable – Comparing early 20th Century warming to late 20th Century warming

If human CO2 influence was negligible during early 20th Century warming, what influence (if any) did CO2 have in late 20th Century warming and any future theorised warming?

CO2 sensitivity – the great unknown and unanswered climate question, yet we base trillions of dollars of taxpayers money on radical climate policy and climate fixes (wind/solar), based on predictive models that assume CO2 is the fundamental ‘climate control knob’.

Doesn’t sound very sciency or smart to me. Though, welcome to “Climate Crisis Inc.”, the trillion dollar eco-crisis we had to have to satisfy a multitude of political and professional ambitions.

Watts Up With That?

Guest essay by Andy May

Many writers, including Professor Richard Lindzen and Ed Caryl have noticed the remarkable similarity in global warming observed from around 1910 to 1944 and 1975 to 2009. The similarity in slopes exists in all global surface temperature datasets. Figure 1 shows the HadCRUT version 4 dataset and the NASA GISS land (GHCN v3) and ocean (ERSST v4) temperature dataset. We’ve identified the two periods of interest on the figure. All datasets also show some cooling between 1945 and 1975.

Figure 2 shows the two periods overlain with data from the HadCRUT version 4 dataset. This display is scaled to actual average temperature. Unlike Figure one this figure and the next one use smoothed monthly data. In that way, we can see some of the variation within each year.
