Climate continues to change.

I was not always a lukewarmer. When I first started writing about the threat of global warming more than 26 years ago, as science editor of The Economist, I thought it was a genuinely dangerous threat. Like, for instance, Margaret Thatcher, I accepted the predictions being made at the time that we would see warming of a third or a half a degree (Centigrade) a decade, perhaps more, and that this would have devastating consequences.

Gradually, however, I changed my mind. The failure of the atmosphere to warm anywhere near as rapidly as predicted was a big reason: there has been less than half a degree of global warming in four decades — and it has slowed down, not speeded up. Increases in malaria, refugees, heatwaves, storms, droughts and floods have not materialised to anything like the predicted extent, if at all. Sea level has risen but at a very slow rate — about a foot per century.

Also, I soon realised that all the mathematical models predicting rapid warming assume big amplifying feedbacks in the atmosphere, mainly from water vapour; carbon dioxide is merely the primer, responsible for about a third of the predicted warming. When this penny dropped, so did my confidence in predictions of future alarm: the amplifiers are highly uncertain.

Another thing that gave me pause was that I went back and looked at the history of past predictions of ecological apocalypse from my youth – population explosion, oil exhaustion, elephant extinction, rainforest loss, acid rain, the ozone layer, desertification, nuclear winter, the running out of resources, pandemics, falling sperm counts, cancerous pesticide pollution and so forth. There was a consistent pattern of exaggeration, followed by damp squibs: in not a single case was the problem as bad as had been widely predicted by leading scientists. That does not make every new prediction of apocalypse necessarily wrong, of course, but it should encourage scepticism.

That's nice.

Now, why is the month of September all that special, compared to multidecadal trends?
 



Audit Of The HadCrut4 Global Temperature Dataset by John McLean, Ph.D.






SUMMARY:
This report makes more than 70 findings about areas of concern with the HadCRUT4 temperature dataset. These cover the entire process from the measurement of temperatures to the derivation of HadCRUT4 global average temperature anomalies. They relate to the inclusion of data that is obviously in error, inappropriate procedures, poor data processing and significant assumptions about a range of matters including basing conclusions on very little data.

Most of the findings increase the uncertainty in the data and therefore increase the error margin. One however shows that a common but flawed method of data adjustment creates a false warming trend from the adjustments alone. Another finding points out that when stations were closed rather than relocated any distortion in the data remains in the record. Errors are also identified in sea surface temperatures, including some created by a member of the team responsible for that data.

Ultimately it is argued that the flawed data casts doubt on the credibility of IPCC reports that rely on HadCRUT4 data (or earlier versions of the dataset). Due diligence of these matters by governments twenty or more years ago might have avoided poorly-justified policies on climate and energy.

"...An implausible conjecture backed by false evidence and repeated incessantly has become politically correct ‘knowledge,’ and is used to promote the overturn of industrial civilization. What we will be leaving our grandchildren is not a planet damaged by industrial progress, but a record of unfathomable silliness as well as a landscape degraded by rusting wind farms and decaying solar panel arrays. False claims about 97% agreement will not spare us, but the willingness of scientists to keep mum is likely to much reduce trust in and support for science..."

Drastic solutions are necessary, but they won't overturn industrial civilization.​
 
In the 1960s it was the coming ice age; now it's the coming heat wave. All bologna.

That shit again?!

Global cooling?

Scientists noticed that historically, the world had been heading towards an ice age.[67] A minority of scientists in the 1970s and earlier also predicted that the pollution would have cooling effect due to increased cloud cover from factories and other emissions. This actually is a thing and does throw a bit of a curveball into the models and appropriate course of action. For example, after 9/11 global air traffic more or less shut down, and the lack of contrails led to the discovery that airplane contrails act to stabilize air temperature throughout the day[68]. The real world is complicated,[citation NOT needed] and people use science to discover how it works. As such, scientific knowledge marches ever forward, and obviously the world has been warming. But the few works published have been enough for "climate skeptics" to strip mine for quotes.

Trotting out the global cooling trope is sometimes called the ice age fallacy.

Richard Lindzen:

Richard Lindzen was an atmospheric physicist at MIT until May 2013;[1] as expected, he is now a "Distinguished Senior Fellow" at the Cato Institute.[2] He is also affiliated with the industry shill front group Heartland Institute.[3]

Lindzen has had a long career in climatology and worked on the Intergovernmental Panel on Climate Change (IPCC) report. However, he became infamously embarrassing for MIT over the last decade as a member of the Bjørn Lomborg "It's not that bad!" school of global warming. Though Lindzen fully accepts anthropogenic global warming, he claims that predictions made by other climatologists' models are "alarmist" and that temperatures will increase by less than one degree Celsius. He maintains this position[4] even though the one degree barrier has already been broken. Managing to incorrectly predict the past is, in a bizarre way, quite an impressive feat for any scientist.
