The downfall of the proxies

The article below is more significant than its authors appear to realize.  It casts all proxy measurements of temperature into doubt  -- and paleoclimate studies all rely on proxies. For most of the world, thermometer measurements of temperature go back only a couple of hundred years, if that.  So paleoclimatologists  DEDUCE temperatures from what they see in tree rings, sedimentary sea-life, ice-cores etc.  Such things are proxies for actual temperature measurements.

And it has just been revealed that a widely used and completely accepted proxy appears to be severely inaccurate.

There have long been protests at the uncritical acceptance of proxies. Perhaps the most vivid example of proxy inaccuracy was "Mike's Nature trick", where Michael Mann abandoned mention of 20th century tree-ring proxies when he found that they showed a 20th century temperature DECLINE.  Where it could be examined, there was a wide divergence between tree ring proxies and actual temperatures as measured by thermometers.  Tree rings have in other words been shown to be invalid as a measure of temperature.  Any work using them is built on sand.

And Dr Zbigniew Jaworowski's criticisms of the assumed reliability of ice core measurements of gases such as CO2 have often been mentioned.  And he studied ice cores for over 30 years.

And the measurements of actual CO2 levels collated by Ernst Beck from 1812 on diverge strongly from proxy measurements.

So doubts about proxies have been voiced before but have been ignored by Warmists.  The latest study, however should be harder to ignore, given its importance to paleoclimate work.  "Paleoclimatology is bunk" would seem to be a reasonable conclusion given what we now know. Its measurements require a large element of faith and that faith has now been shown to be misplaced


Climate change might be even worse than we think, according to a new study that is challenging the way we measure ocean temperatures.

Scientists suggest that the method used to understand sea temperatures in the past is based on a mistake, meaning our understanding of climate change may be flawed.

The findings indicate that oceans in the past were much colder than thought, meaning that temperatures may be increasing quicker now than realised.

For over 50 years, scientists based their estimates on what they learned from foraminifera - fossils of tiny marine organisms found in sediment cores taken from the ocean floor.

Foraminifera form shells called tests, in which the content of a form of oxygen, called oxygen-18, depends on the temperature of the water.

So changes in the ocean's temperature over time were calculated on the basis of the oxygen-18 content of the fossil foraminifera tests found in sediment.

According to these measurements, the ocean's temperature has fallen by 15°C over the past 100 million years.

But these estimates were based on the principle that the oxygen-18 content of the foraminifera tests remained constant while the fossils were in the sediment.

To test whether oxygen-18 levels changed, the researchers exposed foraminifera to high temperatures in artificial sea water that contained only oxygen-18.

An instrument called NanoSIMS was then used to analyse the chemical content of the fossils.

Results show that the level of oxygen-18 changed without leaving a visible trace.

According to the methodology widely used by the scientific community, the temperature of the polar oceans 100 million years ago were around 15°C higher than current readings.

But in a new study, researchers from the French National Center for Scientific Research (CNRS) are challenging this method.

Instead, they suggest that ocean temperatures may in fact have remained relatively stable throughout this period, which raises serious concerns about current levels of climate change.

Dr Anders Meibom, one of the researchers who worked on the study, said: 'If we are right, our study challenges decades of paleoclimate research.'

'Oceans cover 70 per cent of our planet. They play a key role in the earth's climate.

'Knowing the extent to which their temperatures have varied over geological time is crucial if we are to gain a fuller understanding of how they behave and to predict the consequences of current climate change more accurately.'

An instrument called NanoSIMS was then used to analyse the chemical content of the fossils.

Results show that the level of oxygen-18 present changed without leaving a visible trace.

Dr Sylvain Bernard, lead author of the study, said: 'What appeared to be perfectly preserved fossils are in fact not.

'This means that the paleotemperature estimates made up to now are incorrect.'

Rather than showing a gradual decline in temperature over the past 100 million years, the researchers suggest that the foraminifera had changed their oxygen-18 levels simply to equilibrate with the surrounding water.

The findings indicate that temperature in the oceans have been overestimated.

In terms of next steps, Dr Meibom added: 'To revisit the ocean's paleotemperatures now, we need to carefully quantify this re-equilibration, which has been overlooked for too long.

'For that, we have to work on other types of marine organisms so that we clearly understand what took place in the sediment over geological time.'

Clean Power Plan: Real Costs, Fake Benefits

By Steve Milloy

The Trump Environmental Protection Agency’s proposed repeal of the Obama administration’s Clean Power Plan represents an amazing and long overdue breakthrough in the history of environmental regulation. Not only has no Republican administration ever before mustered the courage to rollback a major EPA regulation, but the Trump administration has done so by directly challenging the rule’s purported health benefits. That’s unheard of.

Although the Clean Power Plan was pitched as being about reducing emissions of greenhouse gases from coal-fired power plants, the benefits of averted climate change is not how the Obama EPA justified the rule on an economic basis. There certainly were no discernible climate change benefits to be claimed as House Science Committee Chairman Lamar Smith (R-Tex.) forced Obama EPA administrator Gina McCarthy to acknowledge in testimony. (Video below).

Instead, the EPA justified the net benefit of the rule on the basis of collateral reductions (so-called “co-benefits” in regulatory parlance) in fine particulate matter (soot or “PM2.5”) emissions from power plants. So while the compliance costs of the Clean Power Plan could be as high as $33 billion per year, the Obama EPA was able to overcome this immense number and coal industry complaints by proferring an even larger off-setting one. The Obama EPA claimed that the rule’s benefits from reducing PM2.5 amounted to as much as $55 billion per year.

What are the supposed $55 billion in economic benefits? That sum is intended to represent the monetized value of thousands of premature deaths allegedly prevented every year by the Clean Power Plan via the co-benefit of reduced PM2.5 emissions. Given that EPA values premature deaths avoided at around $9 million per life “saved”, thousands of lives “saved” times millions of dollars per life “saved” equals tens of billions of dollars in purported annual benefits.

EPA staff invented this calculus in 1996 to justify its first effort to regulate PM2.5. As I wrote on this page at the time (link goes to WSJ, copy of 1997 op-ed below this one), there was no science to support the notion that PM2.5 in outdoor air killed anyone. But EPA regulated anyway, stiff-arming not only the objections and demands rom the Republican controlled Congress for the scientific data underlying its claims, but also stiff-arming the objections of then-Vice President Al Gore who thought the PM2.5 rule too costly.

As it had historically always been difficult for EPA to tighten air quality standards because of costs, the EPA used its imaginary notion that PM2.5-kills as a way to game the cost-benefit analysis. As the Clean Power Plan amply demonstrates, no industry cost-benefit analysis could possibly trump EPA’s thousands-times-millions-equals-billions ruse – that is until, well, Trump.

The Trump EPA has now largely jettisoned the notion that PM2.5 kills. And it has done so in a clever way that not only justifies the repeal of the Clean Power Plan but simultaneously hoists the Obama EPA on its own petard.

The Trump EPA has reduced the Obama EPA-claimed benefits of PM2.5 emissions reductions by as much as a whopping $29 billion per year, which then nets out very favorably against the rule’s anticipated costs of as much as $33 billion per year. Here’s the clever part.

The Clean Air Act requires that air quality standards for pollutants such as PM2.5 be set at a safe level which includes an ample margin of safety for supposedly especially vulnerable populations. The Obama EPA reduced the national outdoor air standard for PM2.5 in 2012 from a level of 15 millionths of a gram per cubic meter of air to 12 — thereby making 12 standard the de facto safe level.

Despite the existence of the 12 standard, the EPA has long claimed that there is no safe level of exposure to PM2.5 and that any inhalation of PM2.5 can cause death within hours of inhalation. But EPA could never lower the PM2.5 standard to zero because such a standard could not be attained even if the economy was entirely shut down.

Neverthless, EPA’s benefit analysis for the Clean Power Plan assumes that PM2.5 does kills people below the 12 standard. But the devilishly clever Trump EPA has simply accepted the Obama-issued PM2.5 standard of 12 at its legal meaning and, so, there are no lives saved by reducing PM2.5 levels below that level. Thus vanished $29 billion in fake Clean Power Plan benefits.

There is a large, robust body of scientific literature that supports the Trump EPA decision — everything from large epidemiologic studies to clinical research to historical air quality episode data to other real-life experiences with PM2.5 to just plain old common sense. Standing against the Trump decision is nothing but dubious, pre-Trump EPA-funded epidemiology, the key data for which pre-Trump EPAs have kept secret from more than 20 years thereby preventing independent analyses. The Obama EPA even defied Congressional subpoena to keep its PM2.5 epidemiologic data hidden from view.

New York Attorney General Keith Schneiderman and green activist groups have already announced they will sue over the repeal. Good luck. When the Supreme Court voted to stay the rule in February 2016, the Court implicitly decided the coal industry and state plaintiffs would prevail on the legal merits alone. That the Clean Power Plan has no economic or climate benefits will just underscore its final demise.

EPA chief Scott Pruitt has hailed the repeal of the Clean Power Plan as the end of the Obama “war on coal.” It’s more like the beginning of the end. The end will be reached when scientific reality about PM2.5 is applied to all the Obama war-on-coal rules.

IMF Chief: We Will Be ‘Toasted, Roasted and Grilled’ by Global Warming

"There has not yet been a single documented case of a person being killed by CO2 related “global warming".  Lagarde is a lawyer by trade.  She has no scientific qualifications

Christine Lagarde, the managing director of the International Monetary Fund (IMF), has joined the ranks of the most ardent climate alarmists, prophesying that Armageddon is coming if the human race does not tackle climate change.

If we don’t address the issues of climate change and inequality, Ms. Lagarde said Tuesday before a major economic conference in Riyadh, “we will be moving to a dark future.”

Speaking directly to the question of global warming, Lagarde said that “we will be toasted, roasted and grilled” if humanity fails to make “critical decisions” regarding carbon emissions.

If the human race wants a future that “looks like utopia and not dystopia,” it needs to address such concerns, Lagarde said, predicting that in 50 years’ time, oil will be a secondary commodity since green energy will have moved into prominence.

Speaking before a major petroleum-producing nation, Lagarde hastened to add that these necessary measures are “well understood” in Saudi Arabia.

Ms. Lagarde is no stranger to exaggerated predictions, having proposed in 2016 that a Brexit victory would lead to 500,000 job losses, while suggesting that Brexit voters are narrow-minded and calling for a “united Europe.”

Ms. Lagarde said she had always admired Britain’s “openness to other nationalities and cultures” and added it was “hard to believe attitudes had changed in such a short space of time.”

In June, President Donald Trump announced the U.S. withdrawal from the Paris Climate Accord, arguing that it was a deeply flawed document that put American workers at an economic disadvantage.

This announcement drew fierce criticism from world leaders and activists, with former UN secretary general Ban Ki-moon accusing Trump of “standing on the wrong side of history.”

Recent reports, however, suggest that Trump’s move has drawn numerous countries in his wake, with a number of other nations quietly withdrawing from the Paris energy goals.

According to Lawrence Solomon of Energy Probe, a Toronto-based environmental organization, Canadian Prime Minister Justin Trudeau is one of the only signers of the Paris agreement who is actually abiding by the exacting demands of the accord.

Most signatories, Solomon notes in an essay in last Friday’s Financial Post, “are ignoring, if not altogether abandoning Paris commitments, undoubtedly because voters in large part put no stock in scary global warming scenarios.”

Moreover, a devastating new study from the prestigious UK-based Lancet journal has revealed that pollution-related diseases—rather than “climate change”—were responsible for an estimated 9 million premature deaths in 2015, or some 15 times more than from all wars and other forms of violence combined.

Pollution is not only the largest environmental cause of disease and premature death in the world today, the study found, but diseases caused by pollution were responsible for roughly 16 percent of all deaths worldwide: “three times more deaths than from AIDS, tuberculosis, and malaria combined and 15 times more than from all wars and other forms of violence.”

So while there has not yet been a single documented case of a person being killed by carbon dioxide related “global warming,” real pollution of air, water and land is killing an average of 25,000 people every day across the globe.

As environmental activists jet around the world complaining of “carbon footprints” and preaching “renewable energy,” they have been remarkably silent regarding the real and present menace that is wiping out millions of human beings around the world.

Whereas the Paris Climate Accord prates about greenhouse gas emissions, it never once mentions the word “pollution” in the entire 27-page document.

Yet not only is pollution control not getting better, in many parts of the world, “pollution is getting worse,” the Lancet study found.

Massive New Coal Boom To Fuel Southeast Asia’s Booming Economies

The International Energy Agency (IEA) reports that about 100 GW of new coal-fired power generation capacity is expected to come online in Southeast Asia by 2040, more than doubling the region’s current coal power capacity. Global coal-fired generation capacity to grow by nearly 50% over today’s levels.

The International Energy Agency (IEA) says the need for cheap electricity in Southeast Asia will drive global demand for coal for power generation through 2040, even as many countries continue to retire coal-fired plants and cancel projects for new coal facilities.

IEA, which is set to release its World Energy Outlook 2017 on November 14, this week said India and Southeast Asia will account for the majority of the use of coal in the coming years, as those areas’ economies continue to grow and demand for electricity rises.

“Coal maintains a strong foothold in [Southeast Asia’s] projected consumption, not only because it is markedly cheaper than natural gas, but also because coal projects are in many cases easier to pursue as they do not require the capital-intensive infrastructure associated with gas,” the IEA said in a report in advance of the release of the November outlook.

The agency said about 100 GW of new coal-fired power generation capacity is expected to come online in Southeast Asia by 2040, increasing the region’s installed capacity to about 160 GW. The IEA said 40% of the new capacity will be built in Indonesia. The group said Vietnam, the second-largest consumer of coal in Southeast Asia behind Indonesia, will become the region’s largest importer of coal by 2040.

A report this week by Wood Mackenzie, a UK-based research and consulting firm with offices worldwide, including five in the U.S., said thermal coal imports by Southeast Asia will more than double to 226 million metric tons by 2035, up from 85 million metric tons today. The group said imports into Pakistan, Bangladesh, India, and other parts of South Asia will jump to 284 million metric tons during that period, a 72% increase from this year’s levels.

At the same time, Chinese imports of coal—China in 2016 again became the world’s top importer of coal, overtaking India—will drop about 40% over the next two decades as the country ramps up its use of other energy sources, including wind and particularly solar, where it dominates the world market in terms of installed solar capacity and the production of solar panels.

China this year has canceled plans for more than 100 new coal plants, although Chinese companies are either building or planning to build more than 700 new coal plants worldwide, according to Urgewald, a German environmental group. Urgewald in July said more than 1,600 coal-fired power plants were either under construction or being planned in 62 countries, a number that would increase global coal-fired generation capacity by 43% over today’s levels.

Kiah Wei Giam, a principal analyst for coal and gas markets at Wood Mackenzie, this week at the Singapore International Energy Week said: “Coal is still the most affordable technology in power generation,” despite “pushback in coal development” due to concerns about pollution. Giam said coal demand will remain high at least until renewable energy sources and energy storage solutions become more economically competitive.

It’s greens, not Lord Lawson, who are anti-science

Did you hear Radio 4’s Today programme back on the 10 August? Do you remember hearing Lord Lawson say that ‘during this past 10 years, if anything, mean global temperature, average world temperature, has slightly declined’?

You probably don’t. Lawson was invited to respond to Al Gore’s new film, An Inconvenient Sequel – an equally boring sequel to An Inconvenient Truth. Lawson’s short interview covered many subjects, and touched on temperature only briefly – almost in passing.

However, this week, the BBC has been forced to apologise for presenter Justin Webb’s failure to challenge Lawson’s claim. According to complaints, the audience was misled by the interview. BBC science presenter Jim Al-Khalili said that hosting Lawson was ‘ignorant and irresponsible’. Physics popstar-professor Brian Cox added that it was ‘highly misleading to give the impression that there is a meaningful debate about the science [of climate change]’. The Green Party co-leader, Jonathan Bartley, said that the interview was: ‘The modern day equivalent of giving the smoking lobby a platform to deny that lighting up has any link to cancer.’

But rather than shedding light on the facts of climate change, these complaints say much more about the strange, intolerant and censorious mindset of environmentalists.

If there is any logic to such livid demands for censure and censorship, it is based on a presupposition that the Today programme’s audience consists of feckless and impressionable morons. But even if this insult were true, the segment in question wasn’t biased. The interview with Lawson followed a discussion with Al Gore, later followed by an interview with Fisher Stevens. (Stevens’ campaigning documentary Before the Flood featured the private-jet-flying, yacht-cruising, carbon-guzzling Leonardo DiCaprio worrying about what everyone else’s CO2 emissions are doing to the planet.) The following morning, Today invited the Met Office’s Dr Peter Stott to respond to Lawson’s claim. The audience would have heard ample arguments from the orthodox side of the debate.

Greens seem to think that debate itself lends credibility to unauthorised opinion. Rather than crediting individuals with the sense to judge comments made by interviewees, environmentalists seem to believe that news programmes must spoon-feed audiences the ‘correct’ answers. This reflects environmentalism’s political schema. Where, in a democracy, authority is given by assent from below, greens prefer the authority of scientific institutions. To permit debate would be to undermine the authority of institutional science – and leave the listener with the bizarre impression that he was free to make up his own mind. In other words, Al-Khalili, Cox and Bartley do not need to know what Lawson said, how it contradicts science, or what the science says. They only need to know that he contradicts The Science, and that he shouldn’t be allowed to speak. ‘Shame on you’, screeched Al-Khalili, to the Today team.

But there’s more. Consider the reaction to one of Lawson’s previous appearances on the Today programme. Following the record-wet January and storms of the 2013-14 winter, Lawson appeared on the show with climate scientist Professor Brian Hoskins to discuss the role of climate change in that winter’s weather. ‘There’s no simple link – we can’t say “yes or no, this is climate change”’, said Hoskins. Lawson emphasised Hoskins’ own equivocation, and pointed to analysis from the Intergovernmental Panel on Climate Change (IPCC), which claims that a link between global warming and extreme weather events has not emerged from the observational data. The Met Office, Lawson rightly pointed out, had predicted a continuation of the dry conditions for that winter, and got it badly wrong. The disagreement was mild, yet Lawson’s mere appearance alongside a climate scientist provoked outrage. By putting Lawson alongside a climate scientist, the BBC had, greens said, given the audience the impression that the two men were equally qualified to speak. Climate warriors do not even trust climate scientists to debate climate sceptics face-to-face.

Green hysteria about the expression of unauthorised opinion is a far more interesting – and dangerous – phenomenon than minute changes in atmospheric temperature. Patronising millions of listeners won’t lead to better understanding of the climate, nor will it help us figure out what to do about climate change if it ever does become a problem. The idea that certain scientific claims are beyond question is far more anti-science than anything a climate-change ‘denier’ might come up with.
