Using A Reference Period Outdated 30 Years, Germany’s DWD Weather Service Turns Cooling Into Warming

by Prof. F. Vahrenholt, Jan 8, 2022 in NoTricksZone


Globally, the deviation of the global mean temperature of the satellite-based measurements from the mean of period 1991-2020 rose slightly in December to 0.21 degrees Celsius. The mean temperature increase since satellite measurements began was 0.14 degrees Celsius per decade. The year 2021 was an average year compared to 2010 to 2020, with 0.134 degrees deviation from the thirty-year average. Six years since 2010 were warmer and 5 years were colder.

This is also true for Germany. But the German weather service gives a different impression

How the German DWD Weather Service turned cooling into warming in 2021  

In its press release on Germany’s weather in 2021, the German Weather Service writes: “The mean temperature [Germany] in 2021 was 9.1 degrees Celsius (°C), 0.9 degrees above the value of the internationally valid reference period 1961 to 1990. 2021 was thus the eleventh year in a row that was too warm.”

Why does the DWD use the internationally no longer valid 1961-1990 reference period? It writes itself elsewhere: “To record the climate and its changes, mean values are formed over a period of 30 years…With the end of the year 2020, the reference period for current climatological assessments was replaced by the 1991 to 2020 period.”

Fudging with the reference period

The DWD thus followed the World Meteorological Organization (WMO)recommendation. But in the press release, the DWD still prefers to use the old, outdated period. The 1991 to 202 0reference period differs from the one of 1961 to 1990 by 1.1 degrees. So the DWD should have written : “2021 was 9.1 degrees, 1.3 degrees cooler than 2020 and even -0.2 degrees Celsius below the average from 1991 to 2020. Since 1991 there have only been 9 years colder than 2021.”

But 0.9 degrees more and the eleventh year in a row that is too warm (compared to the colder period of 1961-1990) of course fits much better with the zeitgeist.

Where Is The Top Of The Atmosphere?

by W. Essenbach, Jan 7, 2022 in WUWT


In my last post, entitled Advection, I was discussing the online MODTRAN Infrared Light In The Atmosphere model. A commenter pointed out that in the past I’d wondered about why the MODTRAN results showed that a doubling of CO2 caused a clear-sky top-of-atmosphere (TOA) decrease in upwelling longwave (LW) radiation of less than the canonical value of 3.7 watts per square meter (W/m2) per doubling of CO2. Here’s that data.

46 STATEMENTS By IPCC Experts Against The IPCC

by Jamie Spry, Dec 2019, in Climatism


THANKFULLY we usually always get to hear the inconvenient and raw truth about taxpayer funded, unelected, bloated government bureaucracies when members eventually leave and are not subject to bullying and financial repercussions. Definitely no exception here…

46 enlightening statements by IPCC experts against the IPCC:

  1. Dr Robert Balling: The IPCC notes that “No significant acceleration in the rate of sea level rise during the 20th century has been detected.” This did not appear in the IPCC Summary for Policymakers.
  2. Dr Lucka Bogataj: “Rising levels of airborne carbon dioxide don’t cause global temperatures to rise…. temperature changed first and some 700 years later a change in aerial content of carbon dioxide followed.”
  3. Dr John Christy: “Little known to the public is the fact that most of the scientists involved with the IPCC do not agree that global warming is occurring. Its findings have been consistently misrepresented and/or politicized with each succeeding report.”
  4. Dr Rosa Compagnucci: “Humans have only contributed a few tenths of a degree to warming on Earth. Solar activity is a key driver of climate.”
  5. Dr Richard Courtney: “The empirical evidence strongly indicates that the anthropogenic global warming hypothesis is wrong.”
  6. Dr Judith Curry: “I’m not going to just spout off and endorse the IPCC because I don’t have confidence in the process.”
  7. Dr Robert Davis: “Global temperatures have not been changing as state of the art climate models predicted they would. Not a single mention of satellite temperature observations appears in the IPCC Summary for Policymakers.”
  8. Dr Willem de Lange: “In 1996 the IPCC listed me as one of approximately 3000 “scientists” who agreed that there was a discernible human influence on climate. I didn’t. There is no evidence to support the hypothesis that runaway catastrophic climate change is due to human activities.”
  9. Dr Chris de Freitas: “Government decision-makers should have heard by now that the basis for the long-standing claim that carbon dioxide is a major driver of global climate is being questioned; along with it the hitherto assumed need for costly measures to restrict carbon dioxide emissions. If they have not heard, it is because of the din of global warming hysteria that relies on the logical fallacy of ‘argument from ignorance’ and predictions of computer models.”
  10. Dr Oliver Frauenfeld: “Much more progress is necessary regarding our current understanding of climate and our abilities to model it.”
  11. Dr Peter Dietze: “Using a flawed eddy diffusion model, the IPCC has grossly underestimated the future oceanic carbon dioxide uptake.”
  12. Dr John Everett: “It is time for a reality check. The oceans and coastal zones have been far warmer and colder than is projected in the present scenarios of climate change. I have reviewed the IPCC and more recent scientific literature and believe that there is not a problem with increased acidification, even up to the unlikely levels in the most-used IPCC scenarios.”
  13. Dr Eigil Friis-Christensen: “The IPCC refused to consider the sun’s effect on the Earth’s climate as a topic worthy of investigation. The IPCC conceived its task only as investigating potential human causes of climate change.”
  14. Dr Lee Gerhard: “I never fully accepted or denied the anthropogenic global warming concept until the furore started after NASA’s James Hansen’s wild claims in the late 1980s. I went to the [scientific] literature to study the basis of the claim, starting with first principles. My studies then led me to believe that the claims were false.”
  15. Dr Indur Goklany: “Climate change is unlikely to be the world’s most important environmental problem of the 21st century. There is no signal in the mortality data to indicate increases in the overall frequencies or severities of extreme weather events, despite large increases in the population at risk.”
  16. Dr Vincent Gray: “The [IPCC] climate change statement is an orchestrated litany of lies.”
  17. Dr Mike Hulme: “Claims such as ‘2500 of the world’s leading scientists have reached a consensus that human activities are having a significant influence on the climate’ are disingenuous … The actual number of scientists who backed that claim was only a few dozen.”
  18. Dr Kiminori Itoh: “There are many factors which cause climate change. Considering only greenhouse gases is nonsense and harmful.”
  19. Dr Yuri Izrael: “There is no proven link between human activity and global warming. I think the panic over global warming is totally unjustified. There is no serious threat to the climate.”
  20. Dr Steven Japar: “Temperature measurements show that the climate model-predicted mid-troposphere hot zone is non-existent. This is more than sufficient to invalidate global climate models and projections made with them.”
  21. Dr Georg Kaser: “This number [of receding glaciers reported by the IPCC] is not just a little bit wrong, it is far out by any order of magnitude … It is so wrong that it is not even worth discussing.”
  22. Dr Aynsley Kellow: “I’m not holding my breath for criticism to be taken on board, which underscores a fault in the whole peer review process for the IPCC: there is no chance of a chapter [of the IPCC report] ever being rejected for publication, no matter how flawed it might be.”
  23. Dr Madhav Khandekar: “I have carefully analysed adverse impacts of climate change as projected by the IPCC and have discounted these claims as exaggerated and lacking any supporting evidence.”
  24. Dr Hans Labohm: “The alarmist passages in the IPCC Summary for Policymakers have been skewed through an elaborate and sophisticated process of spin-doctoring.”
  25. Dr Andrew Lacis: “There is no scientific merit to be found in the Executive Summary. The presentation sounds like something put together by Greenpeace activists and their legal department.”
  26. Dr Chris Landsea: “I cannot in good faith continue to contribute to a process that I view as both being motivated by pre-conceived agendas and being scientifically unsound.”
  27. Dr Richard Lindzen: “The IPCC process is driven by politics rather than science. It uses summaries to misrepresent what scientists say and exploits public ignorance.”
  28. Dr Harry Lins: “Surface temperature changes over the past century have been episodic and modest and there has been no net global warming for over a decade now. The case for alarm regarding climate change is grossly overstated.”
  29. Dr Philip Lloyd: “I am doing a detailed assessment of the IPCC reports and the Summaries for Policy Makers, identifying the way in which the Summaries have distorted the science. I have found examples of a summary saying precisely the opposite of what the scientists said.”
  30. Dr Martin Manning: “Some government delegates influencing the IPCC Summary for Policymakers misrepresent or contradict the lead authors.”
  31. Steven McIntyre: “The many references in the popular media to a ‘consensus of thousands of scientists’ are both a great exaggeration and also misleading.”
  32. Dr Patrick Michaels: “The rates of warming, on multiple time scales, have now invalidated the suite of IPCC climate models. No, the science is not settled.”
  33. Dr Nils-Axel Morner: “If you go around the globe, you find no sea level rise anywhere.”
  34. Dr Johannes Oerlemans: “The IPCC has become too political. Many scientists have not been able to resist the siren call of fame, research funding and meetings in exotic places that awaits them if they are willing to compromise scientific principles and integrity in support of the man-made global-warming doctrine.”
  35. Dr Roger Pielke: “All of my comments were ignored without even a rebuttal. At that point, I concluded that the IPCC Reports were actually intended to be advocacy documents designed to produce particular policy actions, but not a true and honest assessment of the understanding of the climate system.”
  36. Dr Paul Reiter: “As far as the science being ‘settled,’ I think that is an obscenity. The fact is the science is being distorted by people who are not scientists.”
  37. Dr Murry Salby: “I have an involuntary gag reflex whenever someone says the science is settled. Anyone who thinks the science is settled on this topic is in fantasia.”
  38. Dr Tom Segalstad: “The IPCC global warming model is not supported by the scientific data.”
  39. Dr Fred Singer: “Isn’t it remarkable that the Policymakers Summary of the IPCC report avoids mentioning the satellite data altogether, or even the existence of satellites — probably because the data show a slight cooling over the last 18 years, in direct contradiction of the calculations from climate models?”
  40. Dr Hajo Smit: “There is clear cut solar-climate coupling and a very strong natural variability of climate on all historical time scales. Currently I hardly believe anymore that there is any relevant relationship between human CO2 emissions and climate change.”
  41. Dr Richard Tol: “The IPCC attracted more people with political rather than academic motives. In AR4, green activists held key positions in the IPCC and they succeeded in excluding or neutralising opposite voices.”
  42. Dr Tom Tripp: “There is so much of a natural variability in weather it makes it difficult to come to a scientifically valid conclusion that global warming is man made.”
  43. Dr Gerd-Rainer Weber: “Most of the extremist views about climate change have little or no scientific basis.”
  44. Dr David Wojick: “The public is not well served by this constant drumbeat of alarms fed by computer models manipulated by advocates.”
  45. Dr Miklos Zagoni: “I am positively convinced that the anthropogenic global warming theory is wrong.”
  46. Dr Eduardo Zorita: “Editors, reviewers and authors of alternative studies, analysis, interpretations, even based on the same data we have at our disposal, have been bullied and subtly blackmailed.”

Deep freeze in Arctic Europe sends power prices soaring

by T. Nilsen, Nov 28, 2021 in The BarentsObserver


On the Finnmark plateau, between Kautokeino and Karasjok, temperatures dropped down to -35°C on Sunday. The forecast for the coming week shows a temperature anomaly for the last days of November of 10°C below the reference period 1961-1990, the Swedish Meteorological and Hydrological Institute informs.

Coldest out is Nikkaluokta near Gällivare in Norrbotten with -36°C.

In times of climate change, the current freeze comes in sharp contrast to last fall, when meteorologists reported about the hottest October and early November ever measured, with an average of 6,7°C above normal across the Arctic.

Cold weather even sweeps the coast of northernmost Norway where the Arctic waters are kept ice-free by the warm Gulf Stream. In Kirkenes, on the border to Russia, the thermometer read -25°C on Saturday outside the Barents Observer’s office.

On the Kola Peninsula, Sunday November 28 came with temperatures from -18°C to -30°C the news online Severpost reported.

Further east in the Russian Arctic, quickly accumulating sea-ice on the Northern Sea Route has created a critical situation as a number of ships have been trapped in thick sea-ice for several weeks.

NASA Data On Global Sea Ice Area Shows A Growth Equal To The Size Of Belgium Since 1982!

by P. Gosselin,  Nov 30, 2021 in NoTricksZone


Data sources like the National Snow and Ice Data Center show global sea ice has been” drastically decreasing for a long time” and so we need to panic and overhaul the entire carbon economy. We hear this daily in the media.

Surprising global sea ice area findings

But Zoe has analyzed what she characterizes as a “very legitimate source” of data from NASA, (here, or here). And according to her findings, the data from these sources suggest global sea ice loss is not as dramatic as some institutes would like us to believe it is. In fact there ‘s been a gain!

Zoe plotted the data going back 40 years, from 1982 to 2021, the “Global Sea Ice Area Fraction”, which “is a proportion of the entire Earth’s surface that is ice over water.”

“As you can see, about 3.6% (on average) of our planet’s area is covered in ice over water,” reports Zoe. “In the last 40 years, ice over water has INCREASED, and not decreased, as popularly claimed.”

According to Zoe, the observed increase is equivalent to ~30,600 km², or “roughly the size of Belgium”.

Climate Fail: Arctic Sea Ice Growing, Nearing Highest Extent In Two Decades

by T. Lison, Nov 24, 2021 in ClimateChangeDispatch


 

t’s so cold in the Arctic that:

Two icebreakers are on the way to rescue ice-locked ships on Northern Sea Route (snip)

District authorities in the Russian Far East have decided to commission two icebreakers to aid the vessels currently ice-locked in the East Siberian Sea. (snip)

The commissioning of the powerful icebreaking vessels comes as severe sea-ice conditions have taken shippers by surprise. There are now about 20 vessels that either are stuck or struggling to make it across the icy waters.

But what about the Antarctic ice cap?

That’s not about to melt either:

[T]he South Pole also just witnessed a historically cold winter. As reported last month: “Between the months of April and September, the South Pole averaged a temperature of -61.1C (-78F). Simply put, this was the region’s coldest 6-month spell ever recorded, and it comfortably usurped the previous coldest ‘coreless winter‘ on record: the -60.6C (-77F) from 1976 (solar minimum of weak cycle 20).”

In  fact, it turns out that, according to a study released a week ago:

PALEOCLIMATE DATA INDICATE THERE WAS LESS ARCTIC SEA ICE DURING THE PRE-INDUSTRIAL PERIOD THAN IN MODERN TIMES, OR WHEN CO2 CONCENTRATIONS WERE 100 PPM LOWER THAN TODAY (280 VS. 380 PPM).

Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million km².

Physicists: Climate Model Error Overestimates CO2 Impact On Global Temps By Factor Of 5

by K. Richard, Nov 22, 2021 in NoTricksZone


A new study suggests CO2 molecules have little consequential impact affecting outgoing radiation, and that climate models attribute global temperature effects to CO2 that are fundamentally erroneous.

Russian physicists (Smirnov and Zhilyaev, 2021) have published a peer-reviewed paper in the Advances in Fundamental Physics Special Issue for the journal Foundations.

They assesses the role of CO2 molecules in the standard atmosphere and assert “we have a contradiction with the results of climatological models in the analysis of the Earth’s greenhouse effect.”

Key points from the paper include the following:

1. Climate model calculations of CO2’s impact on global temperatures are in error by a factor of 5 as a result of “ignoring, in climatological models, the Kirchhoff law” which says radiators are “simultaneously the absorbers.”

2. Change in the concentration of an optically active atmospheric component (like CO2) “would not lead to change in the outgoing radiative flux.”

3. CO2 molecules “are not the main radiator of the atmosphere.” Water vapor molecules are, and thus they “may be responsible for the observed heating of the Earth.”

Emission Reductions From Pandemic Had Unexpected Effects on Atmosphere

by J. Lee & J. O’Neill, Nov 9, 2021 in JetPropulsionLaboratory


Earth’s atmosphere reacted in surprising ways to the lowering of emissions during the pandemic, showing how closely climate warming and air pollution are linked.

The COVID-19 pandemic and resulting limitations on travel and other economic sectors by countries around the globe drastically decreased air pollution and greenhouse gas emissions within just a few weeks. That sudden change gave scientists an unprecedented view of results that would take regulations years to achieve.

A comprehensive new survey of the effects of the pandemic on the atmosphere, using satellite data from NASA and other international space agencies, reveals some unexpected findings. The study also offers insights into addressing the dual threats of climate warming and air pollution. “We’re past the point where we can think of these as two separate problems,” said Joshua Laughner, lead author of the new study and a postdoctoral fellow at Caltech in Pasadena, California. “To understand what is driving changes to the atmosphere, we must consider how air quality and climate influence each other.”

Published Nov. 9 in the Proceedings of the National Academy of Sciences, the paper grew from a workshop sponsored by Caltech’s W.M. Keck Institute for Space Studies, led by scientists at that institution and at the Jet Propulsion Laboratory in Southern California, which is managed by Caltech. Participants from about 20 U.S. and international universities, federal and state agencies, and laboratories pinpointed four atmospheric components for in-depth study: the two most important greenhouse gases, carbon dioxide and methane; and two air pollutants, nitrogen oxides and microscopic nitrate particles.

Carbon Dioxide

The most surprising result, the authors noted, is that while carbon dioxide (CO2) emissions fell by 5.4% in 2020, the amount of CO2 in the atmosphere continued to grow at about the same rate as in preceding years. “During previous socioeconomic disruptions, like the 1973 oil shortage, you could immediately see a change in the growth rate of CO2,” said David Schimel, head of JPL’s carbon group and a co-author of the study. “We all expected to see it this time, too.”

Using data from NASA’s Orbiting Carbon Observatory-2 satellite launched in 2014 and the NASA Goddard Earth Observing System atmospheric model, the researchers identified several reasons for this result. First, while the 5.4% drop in emissions was significant, the growth in atmospheric concentrations was within the normal range of year-to-year variation caused by natural processes. Also, the ocean didn’t absorb as much CO2 from the atmosphere as it has in recent years – probably in an unexpectedly rapid response to the reduced pressure of CO2 in the air at the ocean’s surface.

17 More Studies Show No Unusual Warming Trend In Recent Centuries…And A Warmer Holocene

by K. Richard, Nov 11, 2021 in NoTricksZone


Cruz et al., 2021 (Argentina)

Argentina’s (Tixi Cave) present annual temperature is 13.8°C. It was 3.5°C (17.3°C), 1.7°C (15.5°C), 3°C (16.8°C), and 4.5°C (18.3°C) warmer than today 3496, 1656, 656, and 160 years before present, respectively. So ~1860 was 4.5°C warmer.

 

 

 

A Potted History of Glaciers

by P. Homewood, Nov 10, 2021 in NotaLotofPeopleKnowThat


A friend recently suggested that “melting glaciers” must surely prove “global warming is true”.

It is a common belief. After all, glaciers are a visible phenomenon and it all sounds logical.

As you know, I have written extensively about glaciers, (see the “glaciers” tab on the sidebar). But it is worth posting this potted history of them:

Summary

The modern day retreat of glaciers is part of a much longer natural cycle. Indeed, we find evidence of that cycle going back long before the Middle Ages.

Lamb, for instance, claims that glaciers in the Alps and Norway were advancing between 800 and 400BC, reaching an extent almost as great as during the Little Ice Age. They advanced again around AD600 to a similar position as before.

In between times, of course, the same glaciers also retreated, both during the Roman Warm Period and the Medieval Warming Period.

Whether man-made warming has played any part in modern glacial retreat, we know that:

  • Most of the retreat since the 18thC occurred before any possible impact from humans.
  • Glaciers were smaller than now in the Middle Ages
  • There is nothing unprecedented or alarming about the current state of the world’s glaciers

All of this is common knowledge amongst glaciologists. But for some reason the world of climate science does not want the public to know.

China’s Climate Goals Hinge on a $440 Billion Nuclear Buildout

by D. Murtaugh & K. Chia, Nov 2, 2021 in BloombergGreen


China is planning at least 150 new reactors in the next 15 years, more than the rest of the world has built in the past 35.

Nuclear power once seemed like the world’s best hope for a carbon-neutral future. After decades of cost-overruns, public protests and disasters elsewhere, China has emerged as the world’s last great believer, with plans to generate an eye-popping amount of nuclear energy, quickly and at relatively low cost.

China has over the course of the year revealed the extensive scope of its plans for nuclear, an ambition with new resonance given the global energy crisis and the calls for action coming out of the COP26 Climate Summit in Glasgow. The world’s biggest emitter, China’s planning at least 150 new reactors in the next 15 years, more than the rest of the world has built in the past 35. The effort could cost as much as $440 billion; as early as the middle of this decade, the country will surpass the U.S. as the world’s largest generator of nuclear power.

Presidents Xi and Putin (and the Hedge Funds!) are laughing at us

by P. Homewood, Nov 8, 2021 in NotaLotofPeople KnowThat


The gap between rhetoric and fact is a perennial feature of politics. But seldom can the chasm between claim and reality have been as wide as that displayed by Alok Sharma at the Cop26 conference in Glasgow. The British president of the latest intergovernmental climate change gathering told the delegates (and the world’s media) that “the end of coal is in sight”, as a result of the agreement he had negotiated.


That was the rhetoric. Now the fact. Not only was the declaration to phase out coal by the 2040s not signed by the world’s top three consumers (China, India and America, which account for more than 70 per cent of the global CO2 emissions from burning the stuff); the pledge itself was neutered by the addition of the get-out “or as soon as possible thereafter”.

Climate change is no catastrophe

by M. Shellenberger, Nov 3, 2021 in Unherd


No global problem has ever been more exaggerated than climate change. As it has gone from being an obscure scientific question to a theme in popular culture, we’ve lost all sense of perspective.

Here are the facts: in Europe, emissions in 2020 were 26% below 1990 levels. In the United States, emissions in 2020 were 22% below 2005 levels. Emissions are likely to start declining, too, in developing nations, including China and India, within the next decade. Most nations’ emissions will be bigger this year than last, due to post-Covid economic growth. But global emissions are still likely to peak within the next decade.

And the result will be a much smaller increase in global average temperatures than almost anyone predicted just five years ago. The best science now predicts that temperatures are likely to rise just 2.5-3°Cabove pre-industrial levels. It’s not ideal, but it’s a far cry from the hysterical and apocalyptic predictions of 6°C, made just a decade ago. A 3°C increase is hardly an existential threat to humanity.

Not that you’d know it, if you had half an eye on the headlines this summer. The floods, fires and heatwaves that plagued the world were, for many observers, proof that the impacts of climate change have already become catastrophic. In Europe, more than 150 people died in flooding. In the United States, wildfire season started earlier and lasted longer, razing hundreds of thousands of acres. Around the world, hundreds died from heatwaves.

But again, it’s worth reminding ourselves of the facts: there has been a 92% decline in the per decade death toll from natural disasters since its peak in the 1920s. In that decade, 5.4 million people died from natural disasters. In the 2010s, just 0.4 million did. Globally, the five-year period ending in 2020 had the fewest natural disaster deaths of any five-year period since 1900. And this decline occurred during a period when the global population nearly quadrupled — and temperatures rose more than 1°C degree centigrade above pre-industrial levels.

A Theory of the Hack

by S. McIntyre, Nov 1, 2021 in ClimateAudit


Two major new BBC programs, The Trick and the Hack That Changed The World, re-visit 2009 Climategate events on the eve of UK hosting the most recent international climate get-together. I was interviewed by The Hack and mentioned in The Trick as a villain.

In today’s article, I’m going to propose a theory of the Climategate hack that is very different from the grandiose conspiracy of Russian intel services and US fossil fuel corporations that is the prevalent fantasy of the climate “community” and chattering classes. Subsequent to my interview with the Hack That Changed, I’ve re-examined and cross-checked documents and noticed some interesting new connections. I don’t know the identity of the Climategate hacker, but do believe that deductions about his profile (e.g. motivated individual vs paid institutional hacker) can be made more intelligently by carefully examining details of what was exfiltrated and when – as I shall do here.

 

‘Guess the climate rules don’t apply to them’

by P. Homewood, Nov 2, 2021 in NotaLotofPeopleKnowThat


Bill Gates and Jeff Bezos were slammed as hypocrites for lecturing the world on the need to combat climate change by reducing carbon footprint while at the same time reportedly vacationing on superyachts off the coast of Turkey.

Multi-billionaire and Microsoft founder Gates celebrated his 66th birthday in Turkey in the company of fellow tycoon and Amazon founder Bezos on Friday.

Bezos was among the 50 guests invited to Gates’ private party beside the Mediterranean. It’s not clear whether any of Gates’ family helped him celebrate at his exclusive bash.

Gates – once the richest man on earth who has dropped to fourth on the Forbes Rich List ranking with $124 billion – transported his guests by helicopter from his $2million-a-week rental yacht ‘Lana’ to the Sea Me Beach club in Fethiye.

The jet fuel used to power helicopters emits 21.095 pounds of carbon dioxide per gallon burned, and helicopters travel approximately 10.75 miles per gallon.

According to reports, Bezos also travelled to Gates’ superyacht by helicopter.

The Blue Origin founder is said to have made the 120-mile round trip journey by chopper from Govoka to the resort town of Fethiye.

Based on the same estimations, Bezos’ helicopter emitted some 215 pounds of carbon dioxide into the atmosphere.

Both Bezos and Gates are reportedly staying on superyachts – each of which emits 7,020 tons of carbon dioxide per year, or 19 tons per day.

The Decline, the Stick and The Trick – Part 1uydi

by S. McIntyre, Nov 2, 2021 in ClimateAudit


One of the central claims of The Trick, if not the most central claim, was that “hiding the decline” was nothing more than an inopportune phrase about a single diagram.

It wasn’t.

The “trick to hide the decline” was an inopportune, if revealing, phrase, but rather than the issue being limited to a single diagram, the inconsistency between the Decline (in observed tree ring widths and densities) and the Hockey Stick temperature reconstructions (primarily based on tree ring widths) was, together with the looting of the Baghdad Museum, the issue that inspired my original examination of Michael Mann’s Hockey Stick and was the driving theme of Climate Audit from its origin up to Climategate.  There are dozens, even hundreds, of Climate Audit articles that, in one way or another, relate back to the conundrum arising from the inconsistency of the underlying proxies and the superficial consistency of the reconstructions.

In this and a couple of follow-on articles, I’ll illustrate the centrality of The Decline vs The Stick in the controversies in the years prior to Climategate.  For the benefit of people that may be new to these disputes, I re-iterate that I never interpreted the late 20th century decline in ring widths as evidence of a decline in temperatures, but as a seriously problematic inconsistency for “reconstructions” relying in large part on tree rings.

April 2003

When I say that the Decline inspired my original examination of Michael Mann’s Stick, it is literally true.

I had become mildly interested in climate issues in late 2002 when the Canadian government was promoting the Kyoto treaty, including in its promotion the assertion that 1998 was the “warmest year” in 1000 years.  This was based on the 2001 IPCC Assessment Report, which included multiple versions of the Hockey Stick graph, one of which was the following:

The Climate Is Changing, And Human Activities Are The Cause”: How, Exactly, Do We Know That?

by F. Menton, Oct 28, 2021 in WUWT


“The climate is changing, and we are the cause.” That is a statement that is so often-repeated and affirmed that it goes way beyond mere conventional wisdom. Probably, you encounter some version or another of that statement multiple times per week; maybe dozens of times. Everybody knows that it is true! And to express disagreement with that statement, probably more so than with any other element of current progressive orthodoxy, is a sure way to get yourself labeled a “science denier,” fired from an academic job, or even banished from the internet.

The UN IPCC’s recent Sixth Assessment Report on the climate is chock full of one version after another of the iconic statement, in each instance of course emphasizing that the human-caused climate changes are deleterious and even catastrophic. Examples:

  • Human influence has likely increased the chance of compound extreme events since the 1950s. This includes increases in the frequency of concurrent heatwaves and droughts on the global scale (high confidence); fire weather in some regions of all inhabited continents (medium confidence); and compound flooding in some locations (medium confidence). (Page A.3.5)
  • Event attribution studies and physical understanding indicate that human-induced climate change increases heavy precipitation associated with tropical cyclones (high confidence) but data limitations inhibit clear detection of past trends on the global scale. (Page A.3.4, Box TS.10)
  • Some recent hot extreme events would have been extremely unlikely to occur without human influence on the climate system. (Page A.3.4, Box TX.10)

So, over and over, it’s that we have “high confidence” that human influence is the cause, or that events would have been “extremely unlikely” without human influence. But how, really, do we know that? What is the proof?

This seems to me to be rather an important question. After all, various world leaders are proposing to spend some tens or hundreds of trillions of dollars to undo what are viewed as the most important human influences on the climate (use of fossil fuels). Billions of people are to be kept in, or cast into, energy poverty to appease the climate change gods. Political leaders from every country in the world are about to convene in Scotland to agree to a set of mandates that will transform most everyone’s life. You would think that nobody would even start down this road without definitive proof that we know the cause of the problem and that the proposed solutions are sure to work.

If you address my question — what is the proof? — to the UN, they seem at first glance to have an answer. Their answer is “detection and attribution studies.” These are “scientific” papers that purport to look at evidence and come to the conclusion that the events under examination, whether temperature rise, hurricanes, tornadoes, heat waves, or whatever, have been determined to be “attributed” to human influences. But the reason I put the word “scientific” in quotes is that just because a particular paper appears in a “scientific” journal does not mean that it has followed the scientific method.

The UN IPCC’s latest report, known as “Assessment Report 6” or “AR6,” came out in early August, loaded up, as already noted, with one statement after another about “high confidence” in attribution of climate changes and disasters to human influences. In the couple of months since, a few statisticians who actually know what they are doing have responded. On August 10, right on the heels of the IPCC, Ross McKitrick — an economist and statistician at the University of Guelph in Canada — came out with a paper in Climate Dynamics titled “Checking for model consistency in optimal fingerprinting: a comment.” On October 22, the Global Warming Policy Foundation then published two Reports on the same topic, the first by McKitrick titled “Suboptimal Fingerprinting?”, and the second by statistician William Briggs titled “How the IPCC Sees What Isn’t There.” (Full disclosure: I am on the Board of the American affiliate of the GWPF.).

Cooked Up Consensus: Lynas et al “Should Rather Be Classified As Propaganda, Bad Science”…”Truly Brazen”

by P. Gosselin, Oct 26, 2021 in NoTricksZone


Martin Landvoigt writes on truth and consensus, climate models, the “fundamental and methodological difficulties” in climate science and how “hard, robust evidence is largely lacking” and so it’s “a matter of weakly substantiated opinions”.

Climate consensus and the climate

By Martin Landvoigt at Philosophieren für alle), Die kalte Sonne
(Text excerpt translated, subtitles added by P. Gosselin)

On this basis, the argument of the supposed consensus in climate science has been presented several times and repeatedly.

Numerous studies are supposed to prove this. In particular, the study: Quantifying the consensus on anthropogenic global warming in the scientific literature – John Cook, Dana Nuccitelli, Sarah A Green, Mark Richardson, Bärbel Winkler, Rob Painting, Robert Way, Peter Jacobs and Andrew Skuce – Published 15 May 2013.

Cook et al 2013 refuted

Arguably the most influential study used by U.S. presidents and other top-level decision makers as evidence for climate policy. Nevertheless, it can be considered refuted:

No signs of a climate emergency for W. Hudson Bay polar bears this year ahead of UN climate meeting

by  S. Crockford’s Polar Bear Science, Oct 17, 2021 in WUWT


Reposted from Dr. Susan Crockford’s Polar Bear Science

By Susan Crockford,

Posted on October 15, 2021 | Comments Offon No signs of a climate emergency for W. Hudson Bay polar bears this year ahead of UN climate meeting

I’ve been told that another complete aerial survey of the Western Hudson Bay polar bear subpopulation (from the Nunavut to Ontario boundaries) was conducted in August this year and that the bears have been hanging out further south than usual. It will be years before the results of the population count are published, of course (especially if it’s good news) but my contacts also say virtually all of the bears are in great condition again this year.

This is significant because W. Hudson Bay bears are one of the most southern subpopulations in the Arctic (only Southern HB bears live further south) and older data from this region is being used to predict the future for the entire global population based on implausible model projections (Molnar et al. 2020). And scary predictions of future polar bear survival are often taken to be proxies for future human disasters (see ‘Polar bears live on the edge of the climate change crisis‘), a point that some activists will no doubt make in the coming weeks, as the long-awaited UN climate change bash #26 (COP26) gets underway in Glasgow, Scotland on October 31.

September Mean Temps In Northern Europe See Little Change Over Past Decades…Snow, Frost Arrive

by P. Gosselin, Oct 17, 2021 in NoTricksZone


Today we look at September mean temperatures at the stations across northern Europe for which the Japan Meteorological Agency (JMA) have enough data. We find fall is not being pushed back as we should expect in a warming world.

The JMA has published the data for September and again we see a continuing warming hiatus.

First we look at the September trends from 6 stations in Ireland since 1991:

 

Urban areas more likely to have precipitation-triggered landslides, exposing growing populations to slide hazards

by American Geophysical Union, Oct 12, 2021 in ScienceDaily


Urban areas may be at greater risk for precipitation-triggered landslides than rural areas, according to a new study that could help improve landslide predictions and hazard and risk assessments.

Landslides cause thousands of deaths and billions of dollars of damage annually. With over half of the world’s population in urban areas, and both urbanization and precipitation extremes expected to increase in the future, understanding how urban landscapes are affected by precipitation-triggered landslides is a pressing need.

The new study used a large database of precipitation-triggered landslides across the Pacific coast of the U.S. and isolated the influence of precipitation changes using a specific type of computer model. When the researchers controlled for other factors, like slope steepness, rock type, and wildfire, they found that urban landslide hazard was up to 10 times more sensitive to variations in precipitation than in rural areas. That means that the same increase in rainfall in rural and urban areas could be 10 times more likely to cause a landslide in a city.

The new research is published in the AGU journal Geophysical Research Letters, which publishes high-impact, short-format reports with immediate implications spanning all Earth and space sciences.

Where Have All The Disasters Gone?

by W. Essenbach, Oct 14, 2021 in WUWT


I read today that the EU is using an estimate of US$68 per tonne of CO2 emissions for the purported cost of the damages done by CO2. This is known by a Newspeak term as the “Social Cost Of Carbon”.

It made me wonder—using this estimate, what is the overall total estimated damage done by humans from emitting CO2?

The answer is $97 TRILLION dollars since 1950.

YIKES! That’s about five times the 2020 US Gross Domestic Product (the value of everything produced in the US during that year).

So I thought I’d take a look at the various largest weather-related disasters. I got the big-disaster data from Wikipedia here and arranged it by type of disaster. All values are in 2020 dollars, that is to say, they’re adjusted for inflation. Here is the result.

Aussie Met Bureau – making up 13 years of missing temperature data

by D. Mason-Jones, Oct 15, 2021 in WUWT


Upon finding a 13-year gap in its data for an important weather station in Queensland, the Australian Bureau of Meteorology homogenised data from 10 other locations to fill-in the missing years. One of these places was more than 400km away and another almost 2.5 degrees of latitude further South.

Is the resulting data credible? No, is the conclusion reached in a research Report by Australian scientist, Dr. Bill Johnston.

When the US Army Air Force (USAAF) closed its heavy bomber transit base at Charleville at the end of the Second World War the aerodrome reverted to civilian status. The base had been a link in the ferry route delivering aircraft from factories in the US to the war zone.
