THE global warming climate change scare has absolutely nothing to do with the environment or “Saving The Planet”. Rather, its roots lie in a misanthropic agenda engineered by the environmental movement of the mid 1970’s, who realised that doing something about claimed man-made “global warming” would play to quite a number of the Left’s social agendas.

IN THEIR (UN IPCC) OWN WORDS:

*

ENERGY rationing and the control of carbon dioxide, the direct byproduct of cheap, reliable hydrocarbon energy, has always been key to the Left’s Malthusian and misanthropic agenda of depopulation and deindustrialisation. A totalitarian ideology enforced through punitive emissions controls under the guise of “Saving The Planet”.

STANFORD University and The Royal Society’s resident global warming alarmist and population freak Paul R. Ehrlich spelled out in 1976 the Left’s anti-energy agenda that still underpins the current ‘climate change’ scare :

Giving society cheap, abundant energy would be the
equivalent of giving an idiot child a machine gun
.”
– Prof Paul Ehrlich, Stanford University/Royal Society fellow

*

THE creator, fabricator and proponent of global warming alarmism Maurice Strong, founded UNEP and ‘science’ arm, the UN IPCC, under the premise of studying only human (CO2) driven causes of climate change.

STRONG and the UN’s charter and agenda was clearly laid out before the ‘science’ of climate change was butchered and tortured to fit the global warming narrative…

Isn’t the only hope for the planet that the industrialized civilizations collapse? Isn’t it our responsiblity to bring that about?” – Maurice Strong, founder of the UN Environment Programme (UNEP)

Current lifestyles and consumption patterns of the affluent middle class – involving high meat intake, use of fossil fuels, appliances, air-conditioning, and suburban housing – are not sustainable.” – Maurice Strong, Rio Earth Summit

It is the responsibility of each human being today to choose between the force of darkness and the force of light. We must therefore transform our attitudes, and adopt a renewed respect for the superior laws of Divine Nature.“ – Maurice Strong, first Secretary General of UNEP

*

WHY CO2?

ATMOSPHERIC Physicist, MIT Professor of Meteorology and former IPCC lead author Richard S. Lindzen, examines the politics and ideology behind the CO2-centricity that drives the man-made climate change agenda.

LINDZEN’S summary goes to the very heart of why Carbon Dioxide has become the centre-piece of the ‘global’ climate debate:

“For a lot of people including the bureaucracy in Government and the environmental movement, the issue is power. It’s hard to imagine a better leverage point than carbon dioxide to assume control over a society. It’s essential to the production of energy, it’s essential to breathing. If you demonise it and gain control over it, you so-to-speak, control everything. That’s attractive to people. It’s been openly stated for over forty years that one should try to use this issue for a variety of purposes, ranging from North/South redistribution, to energy independence, to God knows what…”

•••

“CO2 for different people has different attractions. After all, what is it? – it’s not a pollutant, it’s a product of every living creature’s breathing, it’s the product of all plant respiration, it is essential for plant life and photosynthesis, it’s a product of all industrial burning, it’s a product of driving – I mean, if you ever wanted a leverage point to control everything from exhalation to driving, this would be a dream. So it has a kind of fundamental attractiveness to bureaucratic mentality.”

SCIENCE Matters‘ Ron Clutz on the myth of CO2 as a significant driver of global warming climate change and our weather:

To believe humans are dangerously warming earth’s climate, you have to swallow a bunch of unbelievable notions.

  • You have to think the atmosphere drives temperature, instead of the ocean with 1000 times the heat capacity.
  • You have to disregard the sun despite its obvious effects from summer to winter and longer term.
  • You have to think CO2 drives radiative heat transfers, instead of H2O which does 95% of the radiative work.
  • You have to think rises in CO2 cause temperatures to rise, rather than the other way around.
  • You have to forget it was warmer than now in the Middle Ages, warmer still in the Roman era, and warmest of all during Minoan times.  And on and on.

The global warmist narrative is full of ideas upside down and backwards, including many reversals of cause and effect.

It is like a massive hot air balloon, so why doesn’t it deflate? Answer:  It is because so many interests are served by keeping it alive and pumping up public fears.

EQUILIBRIUM CLIMATE SENSITIVITY (ECS)

WE are constantly told by the Climate Crisis Industry that the “science is settled”. Yet, the main indicator of a so-called climate “crisis” – Equilibrium Climate Sensitivity or ECS – the hypothesised amount of temperature increase per doubling of CO2, keeps shrinking even as carbon dioxide rises.

CO2 is Life with the rub…

OVERHEATED UN CLIMATE MODELS

THEN there are the failed CO2-centric UN CMIP5 climate models. Overheated climate models that do not accord with observed reality, and yet increase IPCC confidence in dangerous global warming despite ever-increasing divergence from satellite and weather-balloon data…

***

JUST as ECS declines as CO2 increases it becomes harder to see how policy makers can justify the deliberate deindustrialisation of the Western world driven by draconian, UN climate policies based on overheated UN climate models, fear, funding and mass propaganda.

DO politicians even look at empirical data or “the science” anymore? Or does the wicked truth expose their scam, hindering globalist intentions?

THIS eco-scare is strong and will not die quickly. Too many jobs, reputations and egos are now at stake. And, access to unlimited “Save The Planet” taxpayer trillions, completely immune to oversight.

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:

UAH Global Temperature Update for September, 2018: +0.14 deg. C « Roy Spencer, PhD

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.

Latest Global Temps « Roy Spencer, PhD

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.

GLOBAL TEMPERATURE MEASUREMENTS – You Be The Judge!

Satellites Vs Land-Based Thermometers?

Satellites Vs Thermometers?

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

Source: http://www.remss.com/research/climate Archived here – http://www.webcitation.org/6fiQcrQDQ

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:

Source: http://www.remss.com/blog/recent-slowing-rise-global-temperatures Archived here: http://www.webcitation.org/6fiS2rI7k

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

UAH Global Temperature Update for September, 2018: +0.14 deg. C « Roy Spencer, PhD

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.”

DISGRACE : Shameless Link Between Suicide And Climate Change, Circulating The Mainstream Media’s Echo Chamber

“We project that unmitigated climate change (RCP8.5) could result in a combined 9–40 thousand additional suicides (95% confidence interval) across the United States and Mexico by 2050, representing a change in suicide rates comparable to the estimated impact of economic recessions, suicide prevention programmes or gun restriction laws.”

THE study also took into account seasonal variation, levels of poverty, the news of celebrity suicides and even depressive social media commentary that can lead to more death…

“Analysis of depressive language in >600 million social media updates further suggests that mental well-being deteriorates during warmer periods.”

PROFESSIONAL Climate Alarmists Threatening Australia’s Billion Dollar Tourism Industry

‘$40bn at risk’ as climate change threatens tourism | The Australian

“So even the rain that falls isn’t actually going to fill our dams and our river systems…” Tim Flannery 2007

“There is a fair chance Perth will be the 21st century’s first ghost metropolis.”
– Tim Flannery Climate Council

This planet is on course for a catastrophe.
The existence of Life itself is at stake
.”
– Tim Flannery Climate Council

*

WHEN the Abbott Government axed the Climate Commission in 2013, in what was its very first act of government, professional alarmist Tim Flannery and his mates immediately created a Climate Council to keep up their propagandising.

IT wasn’t a hard decision for then PM Abbott to make considering the string of outlandish claims made by Flannery and the Commission…

IN what was to be their final report and parting gift to the Australian taxpayer, the Climate Commission’s 2013 “Critical Decade” report, claimed that there is a one-in-two chance that there will be no humans left on the planet by 2100

“There’s a one in two chance that by 2100 there’ll be no human beings left on this planet. The planet will exist, but it’s just that my granddaughter won’t be part of it. And I think that’s a pretty alarming statistic, probability, one in two chance if we don’t correct our behaviours.” – Former Defence Force chief Admiral Chris Barrie releasing the Climate Commission’s 2013 doomist report

SINCE then, the Climate Council has maintained its position as Australia’s premier alarmism generating machine. Every year the level of hysteria increasing faster than global temperatures.

THEIR latest report couched in pseudo-science and alarmism claims that Australia’s $40 billion tourism industry is at risk thanks to your sinful existence…

Roger Franklin in Quadrant:

This morning Tim Flannery & Co [at the Climate Council] must be tickled pink to see how much adverse publicity they have generated [with their report last week], and not merely in the domestic press. From Pakistan to the Caribbean there are stories today about the slow death of the Great Barrier Reef, the intolerable heat allegedly set to afflict the Red Centre and how big chunks of Hobart will be swallowed by the heat-swollen waters of the Great Southern Ocean.

That there are casualties and collateral damage as a consequence of one organisation’s blinkered determination to promote itself and its allies’ climate cause should not need to be stated…

[T]here were no reassuring words from Queensland Tourism Minister Kate Jones… So how did the tourism minister react to the Climate Council’s codswallop and bleak appraisal of tourism’s future? Why, God help us, she endorsed it!….

That impression that North Queensland (and the Centre and Hobart, too) are not worth a visit would be hard to avoid in light of the Reef-is-dying coverage the Climate Council orchestrated. Below, a collection of international headlines and snippets re-broadcasting word of the Reef’s impending demise:

From Pakistan:

Australian Tourism Industry Under Climate Change Threat

From Singapore:

Climate change threatens Aussie tourism

From the far-off Caribbean:

Australia tourism industry under climate change threat – study

From the Middle East and broadcast to the entire world:

Why are coral reefs important and why are they dying?

From Britain’s home-counties edition of the Guardian:

Tourism is the Australian industry least prepared for climate change, report says

From China:

Climate change to cripple Australian tourism industry: report

From Malaysia:

Australia tourism industry under climate change threat, study warns

From the US, for seniors who travel:

Aussie tourism hotspots threatened by climate change

For international investors:

Australia’s popular tourist destinations are in the climate firing line: report

All in all, not a bad day’s damage for the Climate Council to inflict on an innocent industry.

The Climate Council’s Global Damage — Quadrant Online

THIS latest episode of climate alarmism churned out of Flannery’s panic-factory, based solely on the ‘evidence’ of broken and overheated UN IPCC computer models further trashes Australia’s international reputation, directly affecting the crucial tourist industry and the livelihoods of the good people who are employed within it.

MORE evidence that climate alarmism has cost far more than any slight global warming ever could!

ONLY recently, three surveys conducted showed an estimated 175,000 fewer tourists could visit Australia based on the coral bleaching threat. A threat since proven alarmist and overblown.

AT risk, an estimated 10,000 jobs. How many more are at risk now?

WHO will be made accountable or held responsible for the exaggeration of data and wreckless alarmism? No one, of course. Because again, the worst any climate change alarmist can ever be accused of is an excess of “Save the planet” virtue.

Mad times.

More classic UNEP agitprop to attempt to scare, deceive and convert you.

Remember all these fears and scares are based on failed (overheated) UN/IPCC CMIP5 RCP8.5 climate *models*.

Predictive (UN IPCC) models are not science and do not observe reality. They are predictions based on perceived inputs in and desired results out.

Climate Models Don’t Work

97% of climate models say that 97% of climate scientists are wrong. Yet we base, literally, trillions of dollars of other people’s (taxpayers) money on alarmist climate change policy, schemes and rent-seeking scams (windmills/solar) on overheated, predictive models that do not observe climate reality.

CMIP5 IPCC climate models don’t even ‘model’ clouds, the sun or ocean currents (AMO/PDO).

What possibly could go wrong? /sarc.

RCP8.5 BS in = Alarmist BS out.

It’s no wonder ‘Climate models don’t work’!

Watts Up With That?

Guest essay by Larry Hamlin

In February 2016 climate scientist Dr. John Christy presented testimony to Congress demonstrating that climate models grossly exaggerate and over estimate the impact of atmospheric CO2 levels on global temperatures . Dr. Christy noted in his testimony that “models over-warm the tropical atmosphere by a factor of approximately 3″.

clip_image002

NOAA climate activist scientist Dr. Gavin Schmidt challenged Dr. Christy’s work claiming that it was “partisan” and using vague statistical arguments claimed that Christy’s work improperly presented the performance of climate models. These claims by government scientist Dr. Schmidt peaked the interest of statistics expert Steven McIntyre who was one of the most prominent  experts to expose the flawed science (proxy shenanigans) and mathematics (statistical errors) behind the now disgraced thousand year long global temperature profile infamously known as the “hockey stick” (https://climateaudit.files.wordpress.com/2005/09/ohioshort.pdf).

Dialing Back the Alarm on Climate Change

A forthcoming report points lowers estimates on global warming

By Dr Matt Ridley

Later this month, a long-awaited event that last happened in 2007 will recur. Like a returning comet, it will be taken to portend ominous happenings. I refer to the Intergovernmental Panel on Climate Change’s (IPCC) “fifth assessment report,” part of which will be published on Sept. 27.

[image]
There have already been leaks from this 31-page document, which summarizes 1,914 pages of scientific discussion, but thanks to a senior climate scientist, I have had a glimpse of the key prediction at the heart of the document. The big news is that, for the first time since these reports started coming out in 1990, the new one dials back the alarm. It states that the temperature rise we can expect as a result of man-made emissions of carbon dioxide is lower than the IPPC thought in 2007.

Admittedly, the change is small, and because of changing definitions, it is not easy to compare the two reports, but retreat it is. It is significant because it points to the very real possibility that, over the next several generations, the overall effect of climate change will be positive for humankind and the planet.

Specifically, the draft report says that “equilibrium climate sensitivity” (ECS)—eventual warming induced by a doubling of carbon dioxide in the atmosphere, which takes hundreds of years to occur—is “extremely likely” to be above 1 degree Celsius (1.8 degrees Fahrenheit), “likely” to be above 1.5 degrees Celsius (2.4 degrees Fahrenheit) and “very likely” to be below 6 degrees Celsius (10.8 Fahrenheit). In 2007, the IPPC said it was “likely” to be above 2 degrees Celsius and “very likely” to be above 1.5 degrees, with no upper limit. Since “extremely” and “very” have specific and different statistical meanings here, comparison is difficult.

Still, the downward movement since 2007 is clear, especially at the bottom of the “likely” range. The most probable value (3 degrees Celsius last time) is for some reason not stated this time.

A more immediately relevant measure of likely warming has also come down: “transient climate response” (TCR)—the actual temperature change expected from a doubling of carbon dioxide about 70 years from now, without the delayed effects that come in the next century. The new report will say that this change is “likely” to be 1 to 2.5 degrees Celsius and “extremely unlikely” to be greater than 3 degrees. This again is lower than when last estimated in 2007 (“very likely” warming of 1 to 3 degrees Celsius, based on models, or 1 to 3.5 degrees, based on observational studies). Keep Reading »
