The author notes that ‘while mainstream climate science is replete with published proxy temperature studies showing that temperatures have cycled up and down over the last 2,000 years – spiking during the Medieval Warm Period and then again recently to about 1980 as shown in Figure 12 – the official IPCC reconstructions (which underpin the Paris Accord) deny such cycles.’

We could add ‘and then says the science is settled’.

After deconstructing 2,000-year old proxy-temperature series back to their most basic components, and then rebuilding them using the latest big data techniques, John Abbot and I show what global temperatures might have done in the absence of an industrial revolution, writes Jennifer Marohasy

The results from this novel technique, just published in GeoResJ [1], accord with climate sensitivity estimates from experimental spectroscopy but are at odds with output from General Circulation Models.    

According to mainstream climate science, most of the recent global warming is our fault – caused by human emissions of carbon dioxide.

Dogma rules in California when it comes to supposed climate issues, as harmless and life-giving trace gas carbon dioxide continues to be treated by the government there as a ‘pollutant’.

California legislators have voted to extend a law to cut carbon emissions, weeks after President Donald Trump said the US would withdraw from the Paris climate accord, reports BBC News.

The policy, which requires firms to purchase permits to release pollutants, will be extended to the year 2030. California Governor Jerry Brown said Republicans and Democrats had taken “courageous action” with the move. The US state aims to cut greenhouse gases by 40% from 1990 levels by 2030.

Is there a contradiction in this IB Times report? First it says volcanism causes cooling, then we’re told the resulting volcanic CO2 could have caused warming.

High concentration of mercury identified in ancient sediments suggest that large-scale episodes of volcanism coincided with the end-Triassic mass extinction around 201 million years ago.

It is likely that these huge pulses of volcanic activity led to great environmental perturbations, leading to the extinction of many species living on Earth at the time and setting the scene for the dawn of the dinosaurs.

Previous studies had already shown that volcanic activity was happening around the time of the extinction and there was some evidence for an increase in the concentration of carbon dioxide (CO2) in the atmosphere.

Trees ‘remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues.’ – Wikipedia


If absorbing carbon dioxide is the idea, which is better value for money: big technology, or plain old-fashioned trees?

On May 31, 2017, the world’s first commercial atmospheric carbon-capture plant opened for business in Hinwil, Switzerland, reports Climate Change Dispatch.

The plant, designed and operated by a Swiss company called Climeworks, is different from existing carbon-capture facilities because it filters carbon dioxide out of the ambient atmosphere using proprietary technology, rather than from industrial exhaust, which is quite common.

Climeworks claims their facility will be able to remove 900 tons of carbon from the atmosphere every year. Furthermore, its modular design will allow it to be scaled up as the demand for carbon dioxide increases.

What do they plan to do with said carbon?

China’s BYD F3DM plug-in hybrid [image credit: Mariordo]


Scare stories about man-made global warming or even city pollution cut little ice with Chinese car buyers. The high cost of battery power and/or fear of running out of it on their journeys – range anxiety – seem more of a concern.

Automakers face a dilemma in China’s huge but crowded market: Regulators are pushing them to sell electric cars, but buyers want gas-guzzling SUVs, says Phys.org.

The industry is rattled by Beijing’s proposal to require that electric cars make up 8 percent of every brand’s production as soon as next year. Consumers are steering the other way: First-quarter SUV sales soared 21 percent from a year earlier to 2.4 million, while electric vehicle purchases sank 4.4 percent to just 55,929.

“It’s tough for someone with an EV to come and take away market share from SUVs,” said Ben Cavender of China Market Research Group.

An embarrassing U-turn by the promoters of pointless carbophobia as diesel cars get the role of public enemy.
H/T Daily Mail via GWPF

It’s less than 20 years since the Labour government – backed by the vociferous green lobby and most of the scientific community – urged motorists to abandon their nasty, carbon-emitting, petrol-engine cars and convert to diesel.

With hindsight, looking at the names of the politicians who pushed this revolution – John Prescott, Neil Kinnock (then EU Transport Commissioner), Gordon Brown – we should have known it would end in tears. But at the time we were assured that driving a diesel was good for the planet and buying one was doing a public service.

US Environmental Protection Agency (EPA) chief Scott Pruitt


BBC News all but bursts a blood vessel over the EPA head’s opinion that the climate science ‘debate’ is not settled. Their reaction is to trot out some standard warmist platitudes, which surprises nobody.

US Environmental Protection Agency (EPA) chief Scott Pruitt has said he “would not agree” carbon dioxide is a primary contributor to global warming.

He told CNBC that measuring human impact on the climate was “very challenging” and there was “tremendous disagreement” about the issue.

Mr Pruitt instead insisted that officials needed “to continue the debate” on the issue. His remarks contradict his own agency’s findings on greenhouse gas emissions.

The word “cult” may be a little over the top, but whatever it is, it sure isn’t science, says The Manhattan Contrarian.

Will Happer is an eminent physicist at Princeton who has chosen (along with his colleague Freeman Dyson) to plant a flag on the skeptic side of the climate debate. I’ve had the pleasure of meeting Happer on a couple of occasions.

Recently his name has been floated as a potential candidate for the position of Science Advisor to President Trump. (This is the position that has been held by eco-fanatic John Holdren during the Obama presidency.)  Although it is not final, and others remain in the running, Happer has said that he will take the position if offered.

Yesterday Happer gave an interview to the Guardian newspaper. When it came to the issue of “climate change,” Happer didn’t pull any punches.

When does the UK climate fiasco budget run out? Not any time soon it seems, unless the Treasury squeezes out mad and/or bad ideas like unilateral CCS projects.
H/T GWPF

The UK government spent £100m on a competition to promote carbon capture and storage (CCS) schemes but it all fell apart. This was even after £68m had been spent on a previous competition for CCS, which it cancelled in 2011.

NAO’s report finds that the Department for Business, Energy & Industrial Strategy’s plan to use a second competition to develop and deploy carbon capture and storage was ambitious, but ultimately, unsuccessful when the Treasury pulled the rug away because of uncertainty over costs.

This is from US CLIVAR. If their graph is to be believed the ocean heat content went up by a factor of about 6 between 1980 and 2012. The title of their paper is ‘The global warming hiatus: Slowdown or redistribution? (Earth’s Future)’. Of course ‘missing heat hiding in the ocean’ is not exactly a new claim from climate alarm theorists.

Atmospheric greenhouse gases have continued their steady increase in the new century. Logically, one would expect that global mean surface temperature (GMST) would also continue to increase in the same fashion as experienced in the latter decades of the 20th century.

However, between 1998 and 2013 GMST actually plateaued with much smaller increases than the average over the last 60 years and labeled the “global warming hiatus.” The fact that this slowdown in GMST increase was not predicted by most climate models has led some to question the steady increase in heat predicted under increased greenhouse gas conditions.

Researchers Against CO2

Ron Clutz takes a closer look at the latest attempt to demonise the trace gas carbon dioxide, which as biology tells us is essential to plant life.

Science Matters


The media are reporting stories with a new theme: More CO2 is bad for plant life. This flies in the face of biochemistry, but the activist motivation is clear: They want people thinking CO2 is bad in every way. They don’t want the warming scare undermined by the idea that CO2 along with warming actually helps plant life and agriculture.

The current stories are coming from researchers involved with an outdoor laboratory site called Jasper Ridge, affiliated with Stanford University, my alma mater and home to famous alarmist Stephen Schneider (deceased). The headlines are occasioned by a new paper appearing Sept. 5 in the journal Proceedings of the National Academy of Sciences, authored by Chris Field, director of the Stanford Woods Institute for the Environment..

Headlines Claim, Details Deny

Headlines and claims like those below are appearing this week, but as we shall see, the details do not support the conclusions…

It’s getting tougher every year for ‘warmists’ to dream up climate scare stories that aren’t obviously just that.

James Delingpole, British writer, rants regularly at Breitbart about the utter goofiness of the world’s climate true believers.  He wrote today about a  climate “science” scam  that keeps on rearing its ugly head, in spite of being debunked thoroughly over and over.

Aside from the need to debunk once more, it’s a classic example of the workings of climate science. In this case, one of Delingpole’s articles was supposedly debunked in The Marine Biologist(the magazine of the marine biologist community). He wrote:

There was a time when I would have just ignored it: the guy who wrote it – one Phil Williamson – is the embodiment of Upton Sinclair’s dictum that “It is difficult to get a man to understand something when his salary depends upon his not understanding it.”

Not only is Williamson based at the “University” of East Anglia – aka Climate Alarmism Central, heavily featured in the Climategate scandal…

Ron Clutz features Dr Murry Salby’s new textbook ‘Physics of the Atmosphere and Climate’ which calls into question the narrow-minded thinking behind claims that carbon dioxide is a powerful climate driver, to the virtual exclusion of other factors.

Science Matters

“Fearless Felix” Baumgartner ascended to the stratosphere and stepped into the void from 24.2 miles above the Earth. His speed during the fall reached Mach 1.24, and the Austrian adventurer nailed the landing. October 14, 2012 Wired 

Introduction
Murry Salby is also totally committed to the atmosphere. He is a scientist with such deep and broad knowledge of atmospheric physics that he has written multiple textbooks on the subject. And yet he is not fearful for the future of our climate system, in contrast to many of his colleagues. By stepping away from “consensus” climate alarms, he has shown unusual courage by speaking plainly about the atmosphere and climate, despite attempts to silence him.

Dr. Salby’s latest textbook is entitled Physics of the Atmosphere and Climate (here). I got a copy and have been reading in it to understand where he comes down on various issues related to climate…

Somebody seems to have re-discovered the carbon cycle, and true to form the BBC is keen to spread the word by trying to relate it to buses and jumbo jets.

The seas around the UK and the rest of northern Europe take up a staggering 24 million tonnes of carbon each year. It is a mass equivalent to two million double-decker buses or 72,000 747 jets. The number was produced by scientists studying the movement of carbon dioxide into and out of the oceans.

The first commercial scale plant capturing carbon dioxide from the atmosphere will be built in Switzerland, with the greenhouse gas to be used to improve growth of vegetables, reports E & T Magazine. 

Of course…greenhouse gas…

The plant will be operated by Zurich-based Climeworks, a spin-off company from the Swiss Federal Institute of Technology in Zurich (ETH Zurich), and uses so-called Direct Air Capture (DAC) technology, which relies on a novel filter to extract carbon dioxide from the ambient air.

The gas binds to the surface of the reusable filter. When the filter is filled to its capacity, it is heated to 100°C to release the CO2, which will be used in a nearby greenhouse to enhance vegetable growth.

Climate quiz: just the one question

Tony Heller has a question to ask about climate scientists, here.

isoprene1This may sound like a joke but it seems not – it’s all over the usual blogs and sceptic media. Does it put a spanner in the works? This from The Register’s report:

As world leaders get ready to head to Paris for the latest pact on cutting CO2 emissions, it has emerged that there isn’t as much urgency about the matter as had been thought.

A team of top-level atmospheric chemistry boffins from France and Germany say they have identified a new process by which vast amounts of volatile organic compounds (VOCs) are emitted into the atmosphere from the sea – a process which was unknown until now, meaning that existing climate models do not take account of it.

Image problem for VW

Image problem for VW


Clive Crook at Bloomberg says there are several scandals linked to the VW diesel debacle. Here we’ll focus on one of them, related to so-called climate policies. Was the ‘dash for diesel’ ever a rational policy?

A third scandal, even more costly than the first two, also needs to be noticed and examined. It concerns the economic and environmental policies that first set European car manufacturers and consumers on course to this pile-up.

Remember that “clean diesel” was a government-led initiative, brought to you courtesy of Europe’s taxpayers. And, by the way, the policy had proved a massively expensive failure on its own terms even before the VW scandal broke.

It’s this scandal that teaches the most important lessons.

I pointed Richard Betts to the Charles D. Keeling (Yes, that Charles D. Keeling) and Timothy Whorf paper on lunar tidal cycles and their connection with rapid climate change ‘The 1,800-year oceanic tidal cycle: A possible cause of rapid climate change.’

Here’s what happened:

Basically, Betts ran away. He’s a natural climate change denier. His job is to ‘do outreach’ promoting the Carbon Dioxide causes climate change hypothesis, but maintain plausible deniability that anyone ever showed him what a crock of crap it is compared to more likely explanations.

No science here [image credit: Michigan Chronicle]


The latest absurdity of the climate controversy is summed up at the American Elephants blog.

They are panicking! Some climate people have bet the farm on a dangerously warming earth, and the need to instantly switch to clean natural energy so we aren’t polluting the world by burning nasty coal and using nasty gasoline and creating the CO2 in the atmosphere that is causing all the trouble. It’s our fault.

But we are promised a colder winter, the claims of a lack of sea ice in the Arctic and Antarctic are disproved by satellite photography. There’s millions and millions of subsidies and grants building wind farms and solar arrays, and they are still not producing much energy at all.

The science of global warming is so settled that 20 climate scientists have written to President Obama to ask him to prosecute the people who “have knowingly deceived the American people about the risks of climate change as a means to forestall America’s response to climate change.”
