Climate Change : Who Are The Real Science ‘Deniers’?

Screen Shot 2018-03-19 at 2.37.19 pm.png

EARLIER today I reported on Sydney’s Autumn 38 degree Sun-day, noting that “the usual climate ambulance chasers will be sharpening the lead and filling ink wells to inscribe “climate change” “global warming” on their “extreme weather” report cards, feeling morally-bound to fashionably link mankind’s activities to the follies of nature.” 

IT didn’t take long for Australian Greens’ leader, Senator Richard Di Natale to blame the current bout of extreme, yet, not-out-of-the-ordinary natural disasters, on ‘climate change’.

IN a speech to the Senate, Di Natale cited a government that had been doing “everything it can to slow this country’s transition to renewable energy” such that “Australians are bearing the brunt of their failure.” That failure, according to Di Natale, manifesting in the form of bushfires in Victoria and New South Wales and a cyclone to the North. The fires still burning as the Senator delivered his insensitive rant.

A reaction of little surprise from a leader of the Greens. The minor party with a major bark obsessed with the latest environmental hype. Pushing propaganda to brighten the colour of its own flag, damn the costs and the suffering.

AS well, a reaction of someone who either ignores, refuses or denies Australia’s well ‘established’ bushfire history…

HISTORICAL sample of autumn Victoria and NSW bushfires when CO2 was at ‘safe’ levels (1854 – 1952):

RATHER than spending billions of taxpayers money subsidising windmills and solar panels in a hubristic attempt to ‘change the weather’, it would be far wiser spending the publics hard-earned money on better fire prevention and containment measures to protect people and their property from a natural hazard that has and always will be a part of the Australian existence.



“In the last few days we’ve seen bushfires savage Tathra, Bega and South West Victoria. We’ve seen a cyclone hit Darwin…” 

SENATOR Di Natale quick to blame cyclone Marcus on ‘climate change’ but slow to understand the overall trend in Australian tropical cyclones:


Graph showing the number of severe and non-severe tropical cyclones from 1970-2017 which have occurred in the Australian region. Severe tropical cyclones are shown here as those with a minimum central pressure less than 970 hPa.

A few clicks to the government’s tropical cyclone page reveals ‘unequivocal’ and clear data that, again, the Senator either ignores, refuses or denies the existence of: an ‘inconvenient’ trend of fewer and less intense cyclones as CO2 rises. The exact opposite of what we were promised by global warming alarmists.


FOR so long, climate ‘sceptics’ have been labeled climate/science “deniers” in crude reference to those who deny the holocaust, with the pejorative used in a broader effort to shut down debate and silence dissent. However, when hard evidence is laid out over alarmist rhetoric, it’s not hard to see who in fact are the real deniers of history and indeed, deniers of science.

SYDNEY Autumn Heatwaves Are Not Uncommon

heat wave ahead.jpg

WITH the mercury topping 38C in Sydney over the weekend (hottest in 78 years), the usual climate ambulance chasers will be sharpening the lead and filling ink wells to inscribe “climate change” “global warming” on their “extreme weather” report cards, feeling morally-bound to fashionably link mankind’s activities to the follies of nature.

HOWEVER, heatwaves and fires in Sydney during autumn months are not uncommon, even when CO2 was at ‘safe’ levels…

(2018 atmospheric CO2 levels are currently at ~400 ppm)

A heat wave reaced Sydney to-day, causing the thermometers to register 90.4deg. in the shade. This heat, though much less than was recently recorded in the southern capitals, was far more enervating, owing to the huge percentage of moisture in the atmosphere. Mr. Russell says that only a dozen times in the history of the colony has a higher March temperature been recorded in Sydney, and if the lateness of the month is taken into account, to-day’s heat will go very close to constituting a record. In the evening a cool change set in from the south.

Sydney, Monday
This month has so far proved the hottest March experienced in Sydney. To-day the thermometer mounted to 100.7 [38C] decrees in the city. In the Western suburbs higher readings were recorded. Parramatta registered 104 [40C] degrees. It was very dry and hot with nil exceptionally low percentage of humidity. Much dust was carried by the blustering westerly and north-westerly wind. The forecast for to-morrow is more hot weather with prospects of the cool change, which is so much desired. It is oppressively hot in the city to-night. Inland the weather is hot and dry. A temperature of 105 [40.5C] decrees was reported from Bourke, and 106 [41C] from Jerry’s Plain.

Sydney, March 8.
This month has so far proved the hottest March experienced in Sydney. To-day was a decided scorcher. The thermometer went to 100.7 degrees [38C] in the city, while in the western suburbs higher readings still were recorded. Parramatta had 104 degrees [40C]. It was a very dry heat, with an exceptionally low percentage of humidity. Much dust was carried by blistering westerly and north-westerly winds. A change had been promised for to-day, but the Weather Bureau officials say this change has unexpectedly been held up at about Moruya. For to-morrow the forecast is more hot winds with prospects of a cool change, which is so much desired in Sydney. It was oppressively hot in the city tonight. Inland too the weather is hot and dry. A temperature of 105 degrees [40.5] is reported from Bourke and 106 degrees [41C] from Jerry’s Plains.

During March Sydney experienced the worst heat wave on record, not so much for the Intensity of the heat, but for the duration of the high readings. During the 10 days until yesterday the ‘maximum temperature in Sydney was over 80deg. The maximum on Saturday was 85deg. and to-day 87.2deg [30.5]. Water restrictions will be imposed next week unless rain falls. Sydney has had no substantial falls for 12 months.

Though Autumn is now officially here, the northern half of the State is experiencing a heat-waye. A bushfire is ravaging the Cobar area. The highest temperature in the State yesterday was at Wilcannia (111degrees) [44C], but several other towns were over the 100 [38C] including Cobar 110 [43], Bourke 109 [43], Hillston 105 [40.4], and Broken Hill 101 [38].
Thousands of Sydney people flocked to the beaches seeking relief from the muggy heat last night, but they were disappointed. They found that the water temperature
was one degree higher than that on the beach.
Police and volunteers : early this morning were fighting a bushfire which was racing over grasslands toward the far western town of Hermidale. . .

ARCTIC Temperatures Plunge! (Don’t expect mainstream media to cover it)

THE collective screams and cries over the recent Arctic “heat wave” were deafening. On cue, climate ‘scientists’ and the global warming-obsessed mainstream media took every opportunity to yell “CLIMATE CHANGE” – of the man-made variety, of course…


This slideshow requires JavaScript.

The Guardian wheeled out their usual Arctic alarmist experts to drive home the “unprecedented” event…

“It’s just crazy, crazy stuff,” said Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colorado, who has been studying the Arctic since 1982. “These heat waves – I’ve never seen anything like this.”

Experts say what’s happening is unprecedented, part of a global warming-driven cycle that probably played a role in the recent strong, icy storms in Europe and the north-eastern US.

“The extended warmth really has staggered all of us,” Mottram said.

SIMPLE fact-checking would have shown Serreze, Mottram and The Guardian et. al that these conditions are not “unprecedented”, as evidenced by Paul Homewood

Arctic meltdown silly season is in full swing again!

DMI show the same spike:




But is it an “off the scale event”?

Unfortunately for poor George’s credibility, the answer is no. We had very similar conditions back in 1976:



Read on here…


THE latest DMI confirms what the mainstream media will not – a dramatic temperature plunge north of the 80th northern parallel…


SIMPLE question for Arctic alarmists :

  • What happened to all that heat-trapping CO2 from our SUV’s? Or, is the recent temperature spike in the Arctic, that contrastingly led to one of the coldest and snowiest winters in recorded history, merely part of the chaotic and complex system we call weather?

DON’T expect an answer. This temperature correction will not be reported in the fake news media because it clearly doesn’t fit their warming narrative.

SAD, yet true.

TIM FLANNERY – Professor of Dud Predictions and Climate Falsehoods

2017 09 13 Tim Flannery Rays of Hope 3.jpg

TIM FLANNERY, former Climate Commissioner of Australia from 20011-2013 earned $180,000 per year for a three-day working week to make predictions and decisions that affected billions upon billions of dollars of Australian taxpayers’ money.

AFTER being rightly sacked by the Abbott government in 2013, Flannery began his own go-fund-me version of the Climate Commission, the Climate Council, which continues the propagandised rollout of catastrophic climate predictions and unreliable-energy pipe dreams.

NEVER far from the government teat, Flannery is regularly wheeled out by Australia’s government run media monolith their ABC, appearing as resident climate ‘expert’ whenever a catastrophic weather event hits the news cycle, or simply to inject a dose of hysteria into the conversation when climate alarm is waning.

TONIGHT, Flannery appears on Q&A, the ABC’s TV panel discussion program…

TO understand why the ABC and Q&A are so ‘impressed’ by the former ‘Australian of the year’, let’s take a brief look at Flannery’s impressive career of climate predictions and prognostications…

TIM FLANNERY – Curriculum Vitae



In 2004 Flannery said:

“I think there is a fair chance Perth will be the 21st century’s first ghost metropolis. It’s whole primary production is in dire straits and the eastern states are only 30 years behind.”

We are “one of the most physically vulnerable people on the Earth,” and “southern Australia is going to be impacted very severely and very detrimentally by global climate change.” We are going to experience “conditions not seen in 40 million years.”

In 2007 he said:

“…That’s because the soil is warmer because of global warming and the plants are under more stress and therefore using more moisture. So even the rain that falls isn’t actually going to fill our dams and our river systems, and that’s a real worry for the people in the bush. If that trend continues then I think we’re going to have serious problems, particularly for irrigation.”

The one-in-1000-years drought is, in fact, Australia’s manifestation of the global fingerprint of drought caused by climate change.”

In May 2007 he warned that:

“Brisbane and Adelaide – home to a combined total of three million people – could run out of water by year’s end;”

and that the country was facing

“the most extreme and the most dangerous situation arising from climate change facing any country in the world right now.”

In June 2007 he said:

“Over the past 50 years southern Australia has lost about 20 per cent of its rainfall, and one cause is almost certainly global warming. Similar losses have been experienced in eastern Australia, and although the science is less certain it is probable that global warming is behind these losses too. But by far the most dangerous trend is the decline in the flow of Australian rivers: it has fallen by around 70 per cent in recent decades, so dams no longer fill even when it does rain …

In Adelaide, Sydney and Brisbane, water supplies are so low they need desalinated water urgently, possibly in as little as 18 months.”

In 2008 he warned again that:

“The water problem is so severe for Adelaide that it may run out of water by early 2009.”

AND then the rains came, as they always do in the land of “droughts and flooding rains

BY December 2008 Adelaide’s reservoirs were 75% full, Perth’s 40%, Sydney’s 63%, and Brisbane’s reservoir’s were 46% full.

BY 2009 dams for Brisbane, Canberra and Sydney were filled to overflowing.

PRESENTLY Adelaide’s reservoirs are 57%, Perth’s 39%, Melbourne’s 64%, Sydney’s 77%, and Brisbane’s reservoir’s are 83% full.


In 2015 Flannery said:

“Sadly we’re more likely to see them more frequently in the future.”.

Reality check:

A year later, not one severe cyclone was recorded, continuing the downward trend in severity and frequency of tropical cyclones, despite rising CO2/temps…


Graph showing the number of severe and non-severe tropical cyclones from 1970-2017 which have occurred in the Australian region. Severe tropical cyclones are shown here as those with a minimum central pressure less than 970 hPa.

Nature journal confirms:

“Studies project a decrease in the frequency of tropical cyclones towards the end of the 21st century in the southwest Pacific, southern Indian, and Australian regions.”

Australian tropical cyclone activity lower than at any time over the past 550–1,500 years | Nature


Flannery in 2007:

Urged us to invest in “green” geothermal power — pumping water on to hot rocks underground.

He claimed hot rocks in South Australia “potentially have enough embedded energy in them to run Australia’s economy for the best part of a century”, and “the technology to extract that energy … is relatively straightforward”.

The Rudd government gave $90 million for a test plant in SA’s Cooper Basin, but a well collapsed, the site flooded and the project was abandoned.

Andrew Bolt global warming: Will Q&A hold Tim Flannery to account for dud predictions? | Herald Sun


In 2005 Flannery wrote in “The Weather Makers“:

Australia’s east coast is no stranger to drought, but the dry spell that began in 1998 is different from anything that has gone before….The cause of the decline of rainfall on Australia’s east coast is thought to be a climate-change double whammy – the loss of winter rainfall and the prolongation of El Nino-like conditions. 

The resulting water crisis here is potentially even more damaging than the one in the west … As of mid 2005 the situation remains critical… very little time to arrange alternative water sources such as large scale desalination plants.

The result:

$12 BILLION worth of desalination plants built in South Australia, Queensland, NSW and Victoria have all been mothballed without producing a drop of water. All were built in preference to much cheaper dams, because of green bans and because warming alarmists claimed the rains would not return.

FIVE desal plants have been built in Australia. Only Perth’s is used.

COSTS to run each mothballed deal plant are estimated at between $500,000 to $1,000,000 per day, every day until the contracts run out around 2030.

WILL anyone on the Q&A panel or from the supposed ‘bi-partisan’ audience question Flannery on any of his monumental climate prediction failures and brazen climate alarmism?

DON’T hold your breath!


FINAL word from the Leftist and global warming obsessed The Conversation on Flannery…

“How is it that Tim Flannery could have got it so spectacularly wrong? The most obvious factor could well be Flannery’s lack of background in a climate science. He is an academic, however his background is mammalogy – he studied the evolution of mammals.”

MAKE Melbourne Clean and Green Again

This slideshow requires JavaScript.

BACK in my hometown of Melbourne, it is abundantly clear and the evidence “unequivocal” that fossil fuels have devastated this once beautiful city. The “carbon pollution” and rampant environmental devastation is visible in everything you see, smell and touch. 

CAPITALISM and the advent of cheap, abundant and reliable fossil fuel power has created a city of filth, poverty and squalor. It must be stopped.

DRACONIAN climate policy and a state of totalitarianism is the only way to convert Melbourne back into a “sustainable”, “smart city” of tranquil caves and caverns once again.

ENDING capitalism and yielding to the UN’s multi-trillion dollar Paris climate con deal is the only way Melbourne will ever become clean and green again.

IN the meantime, Victoria’s Premier, Chairman Dan Andrews’ plan to make ‘energy’ 40% renewable unreliable by 2025 is guaranteed to put downward pressure on already skyrocketing power prices and ensure jobs and industry remain in Victoria…

8 INCHES Of Catastrophic Global Warming Cooks Dutch Canals


PEOPLE in the Netherlands have been making the most of the freezing weather by ice skating over the country’s famous and now frozen canals.

This week’s ‘Beast From The East’ winter storm caused some of the canals in Amsterdam to freeze over for the first time in six years.

Ice skaters glide over frozen canal in Amsterdam – YouTube

The ice on Amsterdam’s historic Prinsengracht canal was thick enough for residents to lace up their skates and glide across as others played ice hockey and tourists without skates slid on the ice, taking selfies.

“It’s just cool. You can go fast and you see the world from a slightly different perspective,” said skater Noldus Reijnders.

Despite measures taken by Dutch authorities to help the ice develop, there were still some holes and parts of the canal weren’t frozen at all. Reijnders was wearing a special red ice pick around his neck just in case. “If you sink through the ice — and there are still a few dangerous places — you can pull yourself out,” he said.

CLAIM : World’s Coral Reefs Face New Peril From Beneath Within Decades


WITH a stubborn atmosphere failing to warm as predicted, another climate threat was needed to sustain the Climate Crisis industry and keep lazy reporters supplied with junk science to feed their catastrophic climate narrative. Enter “ocean acidification”!

FROM the onset, the term “ocean acidification” was deceptive by design. Oceans are alkaline. The correct ‘scientific’ term for any pH change toward zero is “less alkaline”. Obviously not the scariest of descriptors to shock the public into belief.

“Ocean Acidification” was first referenced in a peer-reviewed study in Nature in 2003, resulting in an explosion of journal articles, media reports and alarmist publications from environmental orgs. It has since gone viral, endorsed by scientists from numerous alarmist institutions including the Royal Society, the IPCC and NOAA who coined it “climate change’s evil twin” in a 2016 report.

A 2016 paper published in the ICES Journal of Marine Science put the issue of “ocean acidification” under the microscope, and found Scientists exaggerating the carbon dioxide threat to marine life…

Applying organized scepticism to ocean acidification research

“Ocean acidification” (OA), a change in seawater chemistry driven by increased uptake of atmospheric CO2 by the oceans, has probably been the most-studied singlem_cover topic in marine science in recent times. The majority of the literature on OA report negative effects of CO2 on organisms and conclude that OA will be detrimental to marine ecosystems. As is true across all of science, studies that report no effect of OA are typically more difficult to publish.

Excerpts from the paper:

Scientific or academic scepticism calls for critical scrutiny of research outputs before they are accepted as new knowledge (Merton, 1973).Duarte et al. (2014) stated that “…there is a perception that scientific skepticism has been abandoned or relaxed in many areas…” of marine science. They argue that OA is one such area, and conclude that there is, at best, weak evidence to support an OA-driven decline of calcifiers. Below, I raise some of the aspects of OA research to which I contend an insufficient level of organized scepticism has been applied (in some cases, also to the articles in this theme issue). I arrived at that conclusion after reading hundreds of articles on OA (including, to be fair, some that also raise these issues) and overseeing the peer-review process for the very large number of submissions to this themed issue. Importantly, and as Duarte et al. (2014) make clear, a retrospective application of scientific scepticism such as the one that follows could—and should—be applied to any piece of/body of research.

Applying organized scepticism to ocean acidification research | ICES Journal of Marine Science | Oxford Academic 

From an article in The Times:

An “inherent bias” in scientific journals in favour of more calamitous predictions has excluded research showing that marine creatures are not damaged by ocean acidification, which is caused by the sea absorbing carbon dioxide from the atmosphere.

It has been dubbed the “evil twin of climate change” and hundreds of studies have claimed to show that it destroys coral reefs and other marine life by making it harder for them to develop shells or skeletons.

The review found that many studies had used flawed methods, subjecting marine creatures to sudden increases in carbon dioxide that would never be experienced in real life.

Dr Browman, who is also principal research scientist at the Norwegian Institute of Marine Research, found there had been huge increase in articles on ocean acidification in recent years, rising from five in 2005 to 600 last year.

He said that a handful of influential scientific journals and lobbying by international organisations had turned ocean acidification into a major issue.

“Such journals tend to publish doom and gloom stories . . . stated without equivocation,” he said. The bias in favour of doom-laden articles was partly the result of pressure on scientists to produce eye-catching work, he added.

“You won’t get a job unless you publish an article that is viewed as of significant importance to society. People often forget that scientists are people and have the same pressures on them and the same kind of human foibles. Some are driven by different things. They want to be prominent.”

Scientists‘ are exaggerating carbon threat to marine life | The Times

ENTER climate alarmist in chief – Peter Hannam – Environment Editor at The Sydney Morning Herald / The Age, with his latest doomsday report peppered with the same old regurgitated buzz lines designed to scare you into belief; “tipping points”, “pressure on governments globally to act”, “catastrophic destruction”, “mass bleaching”…

World’s coral reefs face new peril from beneath within decades

New research, published in the journal Science on Friday, has found the sediments on which many reefs are built are 10 times more sensitive to the acidifying oceans than the living corals themselves. Some reef bases are already dissolving.


“Coral reef sediments around the world will trend towards dissolving when seawater reaches a tipping point in acidity – which is likely to occur well before the end of the century,” he said.


Not loving it enough: coral reefs face multiple threats from climate change, including as it turns out, from below.

At risk will be coral reef ecosystems that support tourism, fisheries and the many other human activities, he said.

The ocean’s acidity has increased about 30 per cent since the start of the industrial revolution, as seas absorb about one-third of the build-up of greenhouse gases in the atmosphere.

“It is vital that we put pressure on governments globally to act in concert to lower carbon dioxide emissions as this is the only way we can stop the oceans acidifying and dissolving our reefs,” Professor Eyre said.

World’s coral reefs face new peril from beneath within decades | The Age


Notwithstanding the evidence owing to the inherent alarmism, exaggeration and journal bias of the OA scare, it might be useful for Hannam to consider this simple explanation of what goes on “beneath” the ocean surface…

Corals evolved during the Cambrian era with CO2 levels at 6,000-7,000 ppm, around 4,000% or 20 times higher than today’s “CO2-starved” environment of 400 ppm. Atmospheric and ocean temps were also far higher than today. Corals are made of Calcium Carbonate (CaCO3) – and could not exist without substantial amounts of CO2 in the atmosphere.


A sound explanation of the fallacy of ‘Ocean Acidification’ …


Thirdly, you raise the specter of what you bizarrely call ocean “acidification”.

The last time I looked, the oceans were pronouncedly alkaline, and even the mad IPCC says the acid-base balance has been altered by only 0.1 acid/base units in the direction of slightly reduced alkalinity. However, that estimate, like much else in the IPCC’s mad gospels, is entirely guesswork, because there is no sufficiently well-resolved global measurement program for ocean pH. However, elementary theoretical considerations would lead us to expect homoeostasis in the acid/base balance of the oceans because the buffering influence of the rock basins in which they live and move and have their being is overwhelmingly powerful. Acid/base neutrality is at a pH of 7.0. The oceans are at about 7.8-8.2 (no one knows, so that the IPCC’s alleged dealkalinization of 0.1 acid/base units is well within the measurement error, so that we cannot actually be sure that it has occurred at all; and, on the elementary ground I have described, it is unlikely to have done so). Besides, there is about 50 times as much CO2 already dissolved in the oceans than there is in the atmosphere, so that even if all of the CO2 in the atmosphere were to make its way into the oceans the pH would scarcely change even in the absence of the overwhelming buffering effect of the rocks. As for calcifying organisms, they are thriving. The calcite corals first achieved algal symbiosis and came into being 550 million years ago (you are too young to remember) during the Cambrian era, when atmospheric CO2 concentration was 25 times what it is today. The more delicate aragonite corals came into being 175 million years ago, during the Jurassic, when CO2 concentration was still 15 times today’s. “Ah,” you may say, “but it is the suddenness of the abrupt increase in CO2 concentration that the fragile corals will not be able to endure.” However, consider the great floods of the Brisbane River (eight of them from 1840-1900 and three of them since). The rainwater that pours into the ocean and meets the Great Barrier Reef is pronouncedly acid, at a pH of 5.4. Yet the corals do not curl up and die. “Ah,” you may say, “but what about the effect of sudden warming on the puir wee corals?” Well, the Great el Nino of 1997/8 gives us the answer to that one. Sudden increases in ocean temperature cause the corals to bleach. There have been two previous Great el Ninos in the past 300 years, and the corals bleached on both those occasions too. It is a natural defense mechanism against natural change. The corals continue to thrive. My brother and his three sport-mad boys dive on the reef every year and, like many others from whom I have heard, find the corals thriving except where the Crown of Thorns infestation has damaged small parts of the reef. Oh, and the Great Barrier Reef Authority, which has been moaning about the effects of rising sea temperatures on the corals, publish a dataset that shows zero increase in sea temperature in the region of the reef throughout the entire period of record. Don’t hold your breath worrying about ocean “acidification”: it can’t happen, even if all the CO2 in the air goes into the ocean.

The Multiple Impacts of “Ocean Acidification” on a Tropical Coral

Takahashi, A. and Kurihara, H. 2013. Ocean acidification does not affect the physiology of the tropical coralAcropora digitifera during a 5-week experiment. Coral Reefs 32: 305-314.

The authors write that “according to the IPCC (2007) models, atmospheric CO2 is predicted to rise to 540-970 ppm by the end of this century and reach a maximum of approximately 1,900 ppm when the world’s fossil fuel reserves are fully exploited,” while noting that “a substantial number of laboratory studies have suggested a decline in coral calcification with a rise in seawater pCO2.” However, they say that recentstudies “have postulated that the sensitivity of corals to elevated levels of CO2 is potentially more diverse than previously considered,” citing the works of Fabricius et al. (2011), Pandolfi et al. (2011) and Rodolfo-Metalpa et al. (2011).

What was done
Intrigued by these new and diverse findings, Takahashi and Kurihara measured the rates of calcification, respiration and photosynthesis of the tropical coral Acropora digitifera – along with the coral’s zooxanthellae density – under near-natural summertime temperature and sunlight conditions for a period of five weeks.

What was learned
The two Japanese researchers found that these “key physiological parameters” were not affected by either predicted mid-range CO2 concentrations (pCO2 = 744 ppm, pH = 7.97, Ωarag = 2.6) or by high CO2concentrations (pCO2 = 2,142 ppm, pH = 7.56, Ωarag = 1.1) over the 35-day period of their experiment. In addition, they state that there was “no significant correlation between calcification rate and seawater aragonite saturation (Ωarag)” and “no evidence of CO2 impact on bleaching.”

What it means
Contrary to what many climate alarmists have long contended, there is mounting evidence that suggests that the negative consequences they predict for the world’s marine life in a future high-CO2 world are by no means assured, nor are they likely to be widespread. Keep Reading »

TOP footnote by Dellers

In the last decade or so, the climate change industry has become so vast and all encompassing, employing so many people, it simply cannot be allowed to fail.

According to a report last year by Climate Change Business Journal, it’s now worth an astonishing $1.5 trillion — about the same as the online shopping industry. If the scare goes away, then all bets are off, because the entire global decarbonisation business relies on it. The wind parks, the carbon sequestration projects, the solar farms, the biomass plantations — none of these green schemes make any kind of commercial sense unless you buy into the theory that anthropogenic CO2 is catastrophically warming the planet and that radical green measures, enforced by governmental regulation, must be adopted to avert it.

It’s no coincidence that the ocean acidification narrative began in the early 2000s — just as it was beginning to dawn on the climate alarmists that global temperatures weren’t going to plan. While CO2 levels were continuing to rise, temperatures weren’t. Hence the need for a fallback position — an environmental theory which would justify the massively expensive and disruptive ongoing decarbonisation programme so assiduously championed by politicians, scientists, green campaigners and anyone making money out of the renewables business. Ocean acidification fitted the bill perfectly.
