    Veganism is the best way to reduce carbon emissions

    Ron,

    Regarding the ability of humans to dramatically reduce their meat consumption:

    When I was doing moderately high-performance training I learned that a human body will not benefit from eating more that 4 ounces (100 gms) of meat in a meal (a diversity of research reporting about that). So, most meat eaters can significantly reduce their meat consumption without any issues. Eat the same number of meat meals, but with smaller meat servings.

    However, there is increasing evidence of the health benefits of eating fewer servings of meat. Simple internet searching finds lots of that learning.

    Also, the following ‘anecdotal, but scientific’ case of very high-performance training indicates that people can transition their diet to be meat free, even though they have canine teeth with a liking for meat. The key is to do it in stages, more rapidly if the heath concerns of not changing the diet are significant (like the ‘now urgent’ need to change to limit and repair the harm done by developed fossil fuel use):

    Science tackles the West’s megadrought

    Regarding criticisms that comments to help understand and correct misunderstandings regarding climate science are ‘politically biased’:

    Undeniably, an evaluation of the history of this issue leads to a consensus understanding that Conservative Movement populists divisively politicized the issue. They promoted pseudoscience and science denial to ‘successfully and harmfully’ appeal for support in their efforts to delay the limitation and correction of harm done by fossil fuel use.

    SkS can be understood to be one of the many developments created in response to that 'successful' harmful populist divisive misleading political marketing.

    See the SkS re-posting of the Thinking is Power item “Science and its Pretenders: Pseudoscience and Science Denial”, particularly the Standford University Encyclopedia of Philosophy “Science and Pseudo-Science” webpage that EddieEvans linked in their comment @5 and my response @6.

    Dang, left an 'o' out of "copious"

  5. Science tackles the West’s megadrought

    Peppers, Adfontes Media's Media Bias Chart places both NPR and Reuters near the pinnacle of un-biased, factual reporting. The chart's methodology is copiusly documented.  Argue with its programmers, not with us.

  6. Veganism is the best way to reduce carbon emissions

    By the way, to the vegans that prefer to eat soy, it's growing is also contributing to deforestation, especially in Brazil's Amazon and Argentina. It's true that most soy is grown feed livestock, but a lot of it to feed people as well. "Impossible Burger" needs to get their protein from another source, and care for the planet, not just their bottom line.

  7. Veganism is the best way to reduce carbon emissions

    Yeah, if one divorces Vegan's hypocritical self-righteousness, misanthopism, inflicted guilt and politics from the issue, I can understand their arguments about meat eating. These animals want to live as well. But then, any animal that's ever been eaten, even by another animal, wants to live too.

    But I wonder about evolved human physiology as well. Could those of us that have bodies adapted to getting some of our nutrition from meat, probably most or all of us, and have since the beginning of our evolution, cope? Why did we evolve canine teeth? To eat plants? Why do strict vegans need to supplement with extra B12? What if that weren't available? IOW, is it natural for us to only eat vegetables? 

    Environmentally, I like the idea of eating meat-like vegetables, vegetables meant to taste like meat, like the "Impossible Burger". It's a great idea, cause I believe that the cattle industry is contributing to not just climate change, but the extinction of numerous other species as well to make room for one. But "Impossible Burger's" protein source is Monsanto's genetically engineered soy (cause they can't find non-GE soy that isn't contaminated with GE transgenes anymore thanks to the rather notorious Monsanto (omg!), and they don't want to use pea protein or something else). Also companies that sell their products, like Trader Joe's, quietly fill their shelves with IB, not caring that people shop there because they mistakenly believe that TJ's doesn't sell GMOs. It's all about the $$$ for them. 

    So a conumdrum. What to eat? Natural meat and vegetables? GMOs? Or only plants? Maybe if I could cook, and wanted to spend countless hours hunting down all the esoteric ingredients recipe books say that you need...

    Science tackles the West’s megadrought

    Additionally, "whom are as biased as one can get" is utterly false. Both NPR and Reuters are widely recognized as straight journalism in its best sense. Compare that to FoxNews, who has now been proven in court documents to be "as biased as one can get" and could face potential bankruptcy as a result.

    Science tackles the West’s megadrought

    Peppers... NPR is merely reporting what a scientific study says in that piece. That's as apolitical as it gets.

  10. Science tackles the West’s megadrought

    One Planet,

    Im not sure why this site is going political, but using NPR, Rueters, as opinion sources, whom are as biased as one can get, turns your comments in to political shenanigans. It expands the line of thought of having a foregone opinion and then seeking out the answers that best, and only best fit your prior conclusion. Might sound familiar.

    In 2020 Trump signed the Executive Order on “Modernizing America’s Water Resource Management and Water Infrastructure.” Oddly this dealt with all the premises of this article above. This went further though and established a Water Subcabinet specifically for the Colorado River region, to interface with tribal, local and area governments about the River.

    You, and quoting several left sided websites, post a belittlement to advance a political agenda and start slinging poo. This is then the level you leave this site as as well then.

    You can go to the archives.gov if you paste the executive order sentence above ( Im sorry I dont know how to condense a link here yet and I have ton study that ) and that article shows a 4 minute read.

    [DB] Please refrain from political rants (partially snipped).

    Science tackles the West’s megadrought

    This April 12 NPR item "Swimming pools and lavish gardens of the rich are driving water shortages, study says" indicates that population growth and climate change are not the only significant factors leading to water shortages.

    And Trump pursuing popular support by complaining about low-flush toilets and limited flow shower heads (reported here and there and everywhere) are examples of the harmful nonsense that Populists can temporarily benefit from (an example of the time limit is presented here).

    Science and its Pretenders: Pseudoscience and Science Denial

    EddieEvans,

    Thanks for pointing to the Stanford University page. It is a great supplement to the Thinking is Power item reposted here on SkS.

    I note that the list of criteria in 'Section 4. Alternative demarcation criteria; Sub-section 4.6 Multi-criterial approaches' starts with the following criteria identifying the practice of Pseudoscience:

    "Belief in authority: It is contended that some person or persons have a special ability to determine what is true or false. Others have to accept their judgments."

    Note that many believers of Pseudoscience that is professed by their "Identified Authority (Authoritarian ruler on the matter that they have passionate beliefs about)" often claim that a 'presenter of the developed consensus understanding regarding climate science and the resulting need to rapidly end the harm of fossil fuel use' is claiming to be 'the authority that others must accept the judgments of'.

    The fact that the original Stanford document was published in 2008 appears to indicate that something is causing a powerful resistance to leadership learning the Truth about Pseudoscience, and not just regarding the climate impact case.

    It appears that the powerful problem is harmful Populist political players as described in the detail in the National Endowment for Democracy's Democracy Digest item "Has populism won the war on liberal democracy".

    The book "Has Populism Won? The war on liberal democracy", by Daniel Drache and Marc D. Froese, presents the diversity of Populists. Example of that diversity is Lula and Bolsonaro of Brazil both being Populists, as are Trump and Sanders in the USA. A common point about all Populists is their selling of different versions of a Big Lie that emotionally triggers support by making misleading, overly simple, claims about things. However, populists can be 'harmful or helpful'. Being misleading is not good. But it can temporarily reduce harm ... unless the 'helpful' Big Lie is 'seen through'.

    Also note that the harmful Populists love to benefit from the promotion of Pseudoscience through the 'scientifically developed' power of misleading targeted marketing. Helpful Populists would be less likely to do that. The climate science case identifies the more harmful, less helpful, Populists.

    A final point. Being scientific, and scientific developments, are no guarantee that harm is being reduced. What is chosen to be researched and how that learning is employed can be helpful or harmful. The science of marketing is an example. Nuclear weapons also prove that point. But misleading marketing is potentially a far more harmful scientifically developed thing.

    Veganism is the best way to reduce carbon emissions

    Funny. I just realized I posted the exact same story on this thread 2 years ago. No matter. It's one worth re-telling.

  15. Rob Honeycutt at 11:47 AM on 13 April 2023
    Veganism is the best way to reduce carbon emissions

    Ron... As a vegetarian of over 40 years, I have to agree with you, though I'd have to add the caveat that not all vegans are militant and self-righteous about their diet. Far too many of them are, though, and it leads to making too many factually inaccurate claims. 

    The rule I've developed for myself over the years is this: I'm vegetarian with caveats. When something culturally important or a unique life experience presents itself in the form of eating meat. Give me the meat.  

    Example: When my Chinese wife's grandmother got up at 5am on Chinese New Year morning to make pork dumplings for the family, as she'd done her entire life... the last thing I'm going to say is "no thank you, I'm a vegetarian." My response is, "These are freaking amazing! Can I have more?" And I consider myself extraordinarily lucky to have shared in this special part of her life.

    Science tackles the West’s megadrought

    Extensive additional reporting regarding the Colorado River challenge is provided by NPR, particularly NPR's KUNC. Search "colorado river" on NPR's website.

    The inability (unwillingness) of the collective users to agree to reduced water use is tragically similar to the global response to the need for climate impacts to be reduced. Each State, or each regional interest, appears to have tried to get the most potential benefit possible. The result is the creation of the current day continuation of harmful over-consumption.

    Another tragic similarity to the climate problem is that the reluctance of groups to reduce their harmful over-consumption produces the requirement for the Federal government (an external governing body) to 'impose restrictions'. That is likely to be abused by harmful populist 'freedom and sovereignty' political players to do their harmful misleading by attacking 'those others' who try to impose restrictions on freedom and sovereignty. The harmful populists will likely also blame 'those other water consumers' of being the real harmful over-consumers (populists thrive on finding ways to misleadingly be more popular by 'attacking or blaming others' - recommended related reading is the book "Has Populism Won? The war on liberal democracy", by Daniel Drache and Marc D. Froese).

  17. Veganism is the best way to reduce carbon emissions

    It always bugs me when Vegans (which seem to be more hateful and judgemental than Vegetarians) try to make people feel bad for being carnivores, or even drinking milk or having some butter.

    It's not that I'm at all defending the meat industry, or the way in general animals are treated by them. And I hate the way some people in Asian countries are mistreating animals too. They're vicious and heartless (but I won't get into that right now). Also, about beef eating and the environment, I agree with Vegans. It is destructive and contributes to Climate Change, obviously, so should be phased out. And any fishing is overfishing these days, which is why I don't eat fish either.

    But I think that Vegan's real issue is not about Climate Change. No, I suspect that their hostility and judgmentalism is actually about an enjoyment of telling people what to do! A hatred of people (there is reason to hate some people though).

    Do Vegans eat plants? Of course. Yet, there's a whole field emerging that says that they, too, are sentient. Feel pain. Want to live. Use all kinds of tricks to foul up predators (like Vegans). What gives them the Right to take that life away just to feed their stomachs? Is it because plants can't say "STOP!" when they are eating them? Can't move out of the way to save themselves? Can't audibly scream? How arrogant of them! So thoughtless. But so human too. :/

    Also, do Vegans have pet cats or dogs? Do they feed them plants? If so, they wont live long. I've seen it. Isn't it hypocritical of them not to call for us to stop owning them?

    Are Vegans calling for only humans and their pets to stop eating meat? What about wild animals? Do they want the lion to lie down with the lamb? All meat eating to end, period? An environmental crash would soon follow. Some people eat insects now. Yech! But anyway, do they judge them too? Insects are animals as well. Want to live. Run when we come.

    You know, they say whenever you point a finger at another person, four more are pointing back at you. Are Vegans perfect? They'd better be if they choose judge an otherwise good person. A great man once said not to judge others because with the measure you mete out to them, it will be meted out to you in return. A more modern way of saying that is that people who live in glass houses shouldn't throw stones. People can lay out their beliefs, and that's fine, but don't make it personal (except for real dicks) unless they themselves are utterly flawless. Are they? Only they know.

    So I do eat poultry. You see, you gotta eat to live. That's just the way it works on this planet. But I try to find poultry that's raised humanely. Anyway plants, or animals, they ALL want to live as well. So you gotta make a choice. The alternative is to eat already dead things - or starve.

  18. Science and its Pretenders: Pseudoscience and Science Denial

    In the context of climate deception, I started my morning learning about Karl Popper's explanations for science and pseudo-science.  I came across this Standford University Encyclopedia of Philosophy Science and Pseudo-Science page. It's broad but may add to unavailing climate deceivers more quickly and thoroughly. I hope this helps someday.

    2023 SkS Weekly Climate Change & Global Warming News Roundup #14

    This article from CleanTechnica.com describes how the North East Power system (PJM) is making gas power plants repay funds that were given to them to provide "reliable power".  In December 2022 Winter storm Elliott took out up to 23% of "always on" gas generators.  Meanwhile, wind generators provided over two times their promised electricity. 

    Rules put in place after a similar storm in 2014, when gas generators also failed to work, fine producers who do not produce as they promised and reward generators who provide excess power (not to mention recent Texas gas fiascos blamed on renewable energy).

    Perhaps we will be able to avoid these consistent power shortages in bad weather when we have an all renewable energy system.

    Two attempts to blame global warming on volcanoes

    Bob Loblaw @54,

    I agree that JohnSeers was seeking a debunking of the claim that the evidence of significant rapid recent climate system changes was significantly due to underwater volcanoes heating the oceans.

    I think it could be helpful to always clarify a 'climate change' question or claim in the context of 'its significance related to the evidence of significant rapid recent climate system changes'. And there are 2 dominant verifiable (real based on evidence) rapid recent changes:

    • Increased CO2 levels
    • Increased global average surface temperature (and warmer oceans)

    The evidence and developed understanding to date is so robust that it is very unlikely that fossil fuel use is not the dominant cause of those verifiable rapid recent changes.

    As your helpful comment confirms, that part of the science is almost as certain as science can get on any matter (part of the reason many IPCC participants see no value in 'another update'). That leads to misleading political actions hoping to benefit from the popularity of limited awareness and related increased misunderstanding which is limitless. Verifiable evidence always limits the range of believable explanations ...

  21. Two attempts to blame global warming on volcanoes

    I had presumed that JohnSeers' question @ 49 was with respect to the direct heating effects of undersea volcanoes, rather than any indirect effects associated with CO2 emissions, etc.

    Oceans are an important mechanism of heat transfer. Globally, tropical and subtropical regions absorb much more solar radiation than they emit back to space, so they show a net gain via radiation. Polar and sub-polar regions are the opposite - they lose more by IR emission to space than they absorb from solar radiation.

    The climate system re-balances those regions of gain/loss by transporting energy poleward, and this happens via circulation in both the atmosphere and the oceans. Ocean currents such as the Gulf Stream, etc. move large amounts of energy.

    And both land areas and ocean floors show vertical heat transport from the interior of the earth to the surface - but as discussed in the link I gave in comment #50, the amounts are small. And as pointed out in comments, to argue that current surface warming is the result of this flux of heat from the earth's core (via volcanoes or regular conduction) would require massive undetected increases in that geothermal heat flux.

    Ain't happening, and anyone arguing that it is (without evidence) can be assumed to be badly uninformed (or mis-informed).

  22. Two attempts to blame global warming on volcanoes

    The idea of heating the oceans from below has so many things wrong it. Firstly, I highly recommend Bob's link to get a feel for the scale of different heat sources. Secondly, consider the vertical temperature profile of the oceans - rather consistant with heating from above not below wouldnt you think? And finally, to explain the rapid rise in ocean heat content, this is postulating the amount of heat being emitted geothermally has dramatically increased in recent years and yet is undetectable by observations of volcanism and vertical ocean temperature profiling. This is all about ignoring the simple, obvious explanation which is consistant with all of other data (adding CO2 to atmosphere from burning fossil fuels) and going for the extremely improbable, supported by no evidence at all, presumably because the likely explanation is unpalatable. I dont believe this is rational thinking.

  23. One Planet Only Forever at 02:18 AM on 5 April 2023
    Two attempts to blame global warming on volcanoes

    JohnSeers @49,

    In addition to the responses by Bob and Rob I suggest that the following fairly obvious questions, with fairly obvious answers, are raised by that 3rd volcanic impact possibility:

    1. What is the evidence that underwater volcanic releases have dramatically increased recently in a way that explains the recent rapid increase of atmospheric CO2 levels and global average surface temperature increase?
    2. What has happened to all of the excess CO2 poduced by burining fossil fuels if it hasn't been causing the increase of atmospheric CO2 levels?
  24. Rob Honeycutt at 01:05 AM on 5 April 2023
    Two attempts to blame global warming on volcanoes

    JohnSeers @49...  I've heard that one many times before, at least relative to rising atmospheric CO2. What those who make that claim fail to recognize is that CO2 from underwater volcanoes would merely be dissolved into seawater before reaching the surface. It would lead to greater ocean acidification but any atmospheric changes would be limited to the second order effect from changes in the ocean/atmosphere exchange of CO2. 

    This argument seems more of a "what if" argument someone made up, didn't research, and spun up into a new denial theory.

  25. Two attempts to blame global warming on volcanoes

    JohnSeers @49:

    Without seeing details of the claim you are mentioning, it sounds like that would be a variation on the geothermal heat myth. You can read more about that here:

    https://skepticalscience.com/underground-temperatures-control-climate.htm

  26. CO2 lags temperature

    Terry2 @ 64:

    Are you referring to the quote directly under the "Climate Myth" label? That is not a quote from the Science article - it is a quote from U.S. Rep Joe Barton. You can find the exact quote if you follow the "Full Statement" link immediately below the quote. It's Joe's interpretation of what he read (hopefully - he might just be repeating what someone else said) in the Science paper.

  27. Two attempts to blame global warming on volcanoes

    There is a third argument made that volcanoes cause global warming. Many underwater volcanoes heat the ocean and transfer heat via the PDO, AMO, ENSO etc.

    Is there any debunking of that anywhere?

  28. Inside the quest to develop long-range tornado forecasts

    Can someone please tell me the approximate minimum depth of the Atlantic ocean off the coast of Newburyport Mass. when vast amounts of water was locked up in the ice caps ? In other words, how much less than current sea level. 200 feet ? IWhen I have talked with captains of dredgers over the past 50 years, many of them have pulled up mammoth skeletons with spear points, skeletons of saber-tooth tigers, camels and other Pleistocene species many miles off the coast, so I suspect that the seal and mammoth hunters from the Spain-French occupied eastern North America long before the Indians who crossed Beringia. I believe this idea is supported with DNA evidence as well. Any thoughts ?

    Moderator Response:

    [BL} This is rather off-topic for this blog post. There are many other posts here at Skeptical Science that discuss sea level change over the time scale you are questioning.

    This post on the importance of CO2 over glacial periods shows global sea level changes of about 100m.

    Sea level past 500k years

     

    This post covers sea levels over the past 150,000 years, and includes this figure:

    Sea level past 150k years

    Those are global averages. Along the Mass. coast, glacial ice weight (added, removed) will cause additional local changes. The effect is explained in this post on This Elastic Earth. It includes this animation . (Go to the post to understand what it is showing.)

    Isostatic changes

  29. CO2 lags temperature

    Thank you for your excellent website and all the valuable information. I found this FAQ on CO2 lagging temperature very helpful. I found a copy of the Lorius et al. (1990) paper in Nature and it is great.

    Pardon me if this has been said before in the may posts, but I could not see the direct quote that you present in the paper. The sentiments are definitley there and reflect the findings in the Lorius et al. paper, but not in those exact words.  Perhaps the direct quote you have included comes from a different paper. It seems more like a commentary on the paper.

    Thank you again.

    2023 SkS Weekly Climate Change & Global Warming News Roundup #13

    The Story of the Week raises interesting questions about how 'progress, advancement and improvement' are evaluated (and valued). New technology developments can be very negative in spite of the promotion of positive perceptions about the 'amazing new developments'. Many developed measures of status, like popularity or profit, do not relate to, or indicate, helpfulness or harmfulness.

    More freedom to develop and spread misleading marketing is potentially the most harmful type of 'freedom'. And the most effective counter-measures appear to be educating people by more effectively exposing 'everyone' to the harmful misunderstandings some people try to benefit from developing and spreading. 

    Requiring AI guardrails to make it harder to abuse is helpful. The challenge is ensuring that constantly improved guardrails are being implemented on every AI. But creative people would still figure out how to harmfully abuse those developed systems.

    In addition to rigorous requirements for guardrails, it would be helpful to have the AI developers share their product knowledge with a UN organization of global experts. That team of experts would develop and deploy a powerful AI application that seeks out misleading claims and rapidly responds with effective educational information. If it is well developed it could even produce responses that appeal to people who have become deeply immersed in harmful misunderstanding.

  31. CO2 limits will harm the economy

    As usual, MA Rodger @115 manages to find links to useful links to these things...

    I did read Lomborg's "The Skeptical Environmentalist" many years ago. The major thing that struck me was the way he compartmentalized the various "costs" and alternative solutions. He'd look at one specific/isolated problem caused by climate change, and then claim that it was cheaper to fix that problem after the fact than to avoid the climate change.

    Of course, to avoid climate change you only have to pay for it once - not many times for each individual/isolated problem. He would never add up all the costs of the different isolated problems and compare that total to the one-time "avoid climate change" cost.

    It's like saying "it will cost me $10,000 to fix that leaking roof on my house", and then conclude that it is cheaper to clean and repaint the bedroom ceiling when the water damages it. And then when the leaking roof causes damage to wall insulation, it's cheaper to replace the insulation. And when electrical wiring shorts out, it's cheaper to re-do the wiring. And when the TV gets wet, it's cheaper to replace the TV. And  on, and on, and on.

    Eventually, the rational home owner realizes that it would have been cheaper to fix the roof than to replace the many, many things that the leaking roof damaged. But as long as you can fool the home owner into looking at each individual problem in isolation, you can sell them a paint job, an electrical job, and new TV, etc. If your business is home repair - not roofing - then it becomes a lucrative approach. Also lucrative if your business is to prevent roof repairs.

    MA Rodger's link to the rebuttal is worth reading. Lomborg, not so much. All you need to do is look to see what Lomborg's proposed alternatives are and assess how much effort he puts into making those alternatives happen - as opposed to how much effort he puts into arguing against preventing climate change. (Cue the XKCD cartoon...)

  32. CO2 limits will harm the economy

    retiredguy @112,

    You do specifically ask about rebuttals of Lomborg's verbose 2020 paper 'Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies' and as has been pointed out, this paper is packed full of the usual Lomborg nonsense. I don't know of any specific rebuttal to this paper. I think with a 'broken record' like Lomborg, you need the expertise to unpick his nonsense as well as the dedication to keep at it. A month after this paper, Lomborg published a book 'False Alarm: How Climate Change Panic Costs Us Trillions, Hurts the Poor, and Fails to Fix the Planet' and that did result in a rebuttal.

    As for the paper 'Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies,' we can cut through all Lomborg's nonsense and simply consider his basic argument which is that AGM mitigation preventing large levels of global warming (as in scenario SSP1-1.9) is, according to Lomborg, not as benificial to mankind as allowing fossil fuel use to continue without restriction (as in secanario SSP5-8.5, roughly similar to the previous RCP8.5). From the abstract:-

    Long-term impacts of climate policy can cost even more [than 2030 costs]. The IPCC's two best future scenarios are the “sustainable” SSP1 and the “fossil-fuel driven” SSP5. Current climate-focused attitudes suggest we aim for the “sustainable” world, but the higher economic growth in SSP5 actually leads to much greater welfare for humanity. After adjusting for climate damages, SSP5 will on average leave grandchildren of today's poor $48,000 better off every year. It will reduce poverty by 26 million each year until 2050, inequality will be lower, and more than 80 million premature deaths will be avoided.

    This argument is thus mainly based on the economic predictions set out by IPCC ARs within these SSPs and then downplaying to the point of insignificant the economic damage in a SSP5-8.5 world experiencing +4.4ºC by 2100 (this a central figure in the range +3.3ºC-5.7ºC) and which will continue warming post-2100, the 2300 range being given as  +6.6ºC−14.1ºC.  Now that is scary. (And note in the graphic below, the SSP5/RCP8.5 temperatures are still rising in 2300. There is even more to come.) Lomborg is advocating a really scary future while insisting there is no scary future.

    Warming to 2300 scenarios

    CO2 limits will harm the economy

    retiredguy @112,

    As Bob Loblaw has pointed out, serious pursuers of better understanding may not have bothered to do 'yet another' detailed debunking of Lomborg's nonsense. I read some of his earlier books and was able to easily identify many misleading claims he made. He has a history of changing his claims, but not his motivation to be misleading regarding the climate impact problem and its solutions.

    Based on the title of the 2020 Lomborg item, I am almost certain that this version of his misleading story-telling efforts can be effectively corrected by reading helpful detailed documents like the UNDP's Human Development Reports. I particularly recommend the 2020 HDR which includes a robust evaluation that dispels the myth that GDP is a meaningful measure of advancement.

    Other documents that help people learn how to dismiss the claims of people like Lomborg include:

    That's a new trick for me, jimpsy.

    Similar to the trick I learned when I was young, for multiplying 2-digit numbers by 11:

    • Take the two digits, and insert a space between them.
    • Add the two digits together.
    • Insert the sum in the space you created.

    23x11 becomes 2[space]3, and the sum of 2+3 = 5, so 23x11 = 253.

    47x11 becomes 4[space]7, and 4+7 = 11, so you insert 11 in the space by adding the first 1 to 4 and leaving the second 1 in place, so 47x11 = (4+1)17 = 517.

    An absolutely dastardly trick if I ever saw one...

  35. CO2 limits will harm the economy

    retiredguy:

    Bjorn Lomborg is a broken record, who basically keeps repeating most of the same arguments over and over and over (and over). Much of his stuff has been debunked in a variety of sources (over, and over, and over, and over).

    Is there anything particularly new in that work you linked to? Any reason to spend time on it, since (for me, at least) it has been years (if not decades) since I have seen anything worth reading from him?

    You can read more about his general track record at Desmog.

    ...and for the most, part, I think what he usually has to say bears a strong resemblance to this XKCD cartoon:

  37. CO2 limits will harm the economy

    Can anyone point me to a comprehensive review and response to Bjorn Lomborg's July 2020 article, "Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies" ?

    If I had a nickel for every time I had to remind skeptics that there are two, subtly but distinctly differentiated meanings of the word trick... A simple way to present it, at least in person, is to demonstrate how to mutiply by 9 on your fingers.  The multiplicand is 9.  Count on the fingers of your left hand up to the multiplier, let's say it's 5.  You bend your fifth finger (pinky) down. There are 4 fingers remaining on your left hand, and 5 remaining on your right - 45.  Now, I just showed you a trick....but did I trick you?

    Extreme heat waves in Europe may be linked to melting Arctic sea ice

    Gordon and Bob,

    I agree that discussing 'energy poverty' is getting off-topic. But raising the related problem of 'energy gluttony' seems appropriate, because 'harmful energy gluttony' is a major root of the climate impact problem.

    All I will add is that 'energy gluttony' can be understood to be a major aggravating factor regarding 'energy poverty'.

  40. Extreme heat waves in Europe may be linked to melting Arctic sea ice

    Now that I am looking at the maps that you mention regarding the "energy poverty" issue, it looks like that December high mortality rate is in reference to the 2016-2019 average. The way they worded that suggests that they have not adjusted for seasonal patterns, which makes it very difficult to tell if the December 2022 value is really an unusual case, or just a normal seasonal effect.

    As for the similarity between the "can't keep the home warm" and the "Dec 2022 excess mortality" maps - I am not seeing a strong link. Norway and Finland score high on the excess deaths map, but they are in the lowest category for "problems heating". Switzerland and Austria also show a similar pattern. Romania and Bulgaria are the opposite: they score very low on excess deaths, but are in the highest two categories for "unable to heat the home". The geography of Europe suggests that some countries may be much better prepared for heating in the cold season. There are a lot of variables involved.

    Your definition of energy poverty also seems rather vague. There are a multitude of levels of "negatively affect", and "health and well-being" also covers an awful lot of ground.

    And finally - this is really getting off-topic for the blog post.

  41. Extreme heat waves in Europe may be linked to melting Arctic sea ice

    Thanks for the link, Gordon. For future reference, when you provide a quote like that one, it really helps if you give a proper link to the source, rather than leaving people guessing.

    I can find that quote on page 22. There is very little context there. They repeat the 40,000 number on page 37, where they say:

    Gallagher Re estimates that as many as or more than 40,000 excess deaths were recorded between June and August from heat-related activity in the region, which particularly hit the UK, France, Spain and Portugal. This was conducted based on national-level mortality analysis.

    and then again in the appendix tables on page 52. In none of those cases do they provide any further details on the analysis method.

    Without details on the analysis method, there isn't much hope in trying to come up with an explanation of why they attribute European summer deaths to heat, and other spikes are attributed to other causes. The original quote you provided does state that this was a "preliminary estimate", which suggests that it was not as thorough as they would like.

    You may wish to read this Reaclimate post on heat-deaths vs cold-deaths under a warming climate. It mentions that winter mortality rates in Europe are normally higher - but hopefully an "excess mortality" assessment would take this into account.

    The Eurostat link in comment #1 does not tell us if the 19% "sharp rise" in December 2022 is within a normal range of variability for December, and it does not tell us if they use individual monthly averages for each "excess death" calculation, or an average over several months, a full year, or several years. The quote I gave in comment #2 contains values for four other peaks in the past three years - two in April, and two in November. That suggests that they might not be making monthly base/reference calculations - but it's really hard to tell.

    Methodology is critically important in these sorts of calculations.

  42. Extreme heat waves in Europe may be linked to melting Arctic sea ice

    Bob:

    Here is the LINK to the quote in comment#1.

    Energy poverty is defined as such:

    Energy poverty occurs when energy bills represent a high percentage of consumers’ income, or when they must reduce their household's energy consumption to a degree that negatively impacts their health and well-being."

    A simple example supporting my belief can be found by comparing the MAP in this article with the MAP in this one.  Note that Germany's situation has deteriorated substantially since 2020 due to the war and loss of Nordstream.  You can find the MAP for July here by selecting the the appropriate time series on the top left hand corner.

  43. Solar cycles cause global warming

    As a further follow-up to the responses to retiredguy, note that the Beer et al paper mentioned in comment #60 is from 2000, when a lot of contrarians were still beating the "cosmic rays" drum pretty hard. You can read more about it here. In the past 20 years, that drum has been beaten to death.

    Just over a year ago, I also did a more thorough review of another "it's the sun" paper that SkS was asked about in email. You can read that review to see where the paper went wrong. That paper argued (incorrectly) for "indirect solar effects" in an attempt to get around the weak direct effects (changes in total energy from the sun).

    And finally, reading my comment #62 here in the original thread (instead of in "Recent Comments"), I see that the graph I provided is also in Comment #59.... Plus ca change...

  44. Extreme heat waves in Europe may be linked to melting Arctic sea ice

    Gordon:

    I am still not finding the quote you provided in comment #1 in your link in comment #1 (repeated in comment #3). The word "heat " only appears on that page once, and it is in the text that I quoted in comment #2. The second link that you provided in comment #3 does not contain the word "heat" at all (letting my browser search for it).

    Please check your sources and given a proper reference/source for the quote. To understand the quote, we need more information about context and methodology.

    Your second link does provide Covid-related deaths in raw numbers, but does not let us determine how to transform that into "excess mortality" as a percent - we need to know both a numerator and a denominator to be able to calculate percent.

    As for your closing statement about energy poverty, you are going to have to define what you mean by that term and provide some supporting data/information if you want us to think it is anything more than a belief on your part.

  45. Solar cycles cause global warming

    retiredguy @60,

    A pointed out by responding comment, Beer et al (2000) is quite old and struggles with its solar irradience reconstruction. A more recent paper of which Beer is a co-author is Gray et al (2010) 'Solar influences on Climate'. This concludes by saying:-

    Despite these uncertainties in solar radiative forcing, they are nevertheless much smaller than the estimated radiative forcing due to anthropogenic changes, and the predicted solar cycle‐related surface temperature change is small relative to anthropogenic changes.

  46. Extreme heat waves in Europe may be linked to melting Arctic sea ice

    Hi Bob,

    The quote comes from the paper referred to in the second paragraph link "40,000 people died".  Incidently the paper was written by an insurance company and does not contain any references that I can find to support the claim.  Whilst the excess mortality LINK shows 17% for July and 19% for December it does not distinguish between Covid and other causes.  This LINK, however, does show the number of Covid deaths for the respective periods.  Interestingly, the deaths from Covid in July were higher than in December.  It is well known that more people die during cold periods than during warm (as demonstrated here), however, I believe the main driver behind these increases is energy poverty.

  47. Extreme heat waves in Europe may be linked to melting Arctic sea ice

    Gordon:

    I have not watched the video. Is the quote you provide transcribed from the video? At what time point?

    The link you provide referencing the December 2022 spike generally makes no attempt to attribute the spikes it sees (in any period, let alone Dec 2022). It just reports numbers compared to a reference period. There is a paragraph saying:

    "The EU registered earlier major peaks in excess deaths in April 2020 (+25%), November 2020 (+40%), April 2021 (+21%) and November 2021 (+27%). July 2022 also showed significantly higher than the baseline mortality, possibly due to the heatwaves that affected parts of Europe during the reference period.

    The quote you provided includes the phrase (emphasis added) "...by subtracting from recent decadal averages and COVID-19 spikes...". That means it the raw excess mortality has been adjusted for Covid-19 (a known cause of excess mortality).

    The link you gave also includes this paragraph:

    "Please note that while a substantial increase in excess mortality largely coincides with the COVID-19 outbreak, this indicator does not discriminate among the causes of death and does not identify differences between sex or age.

    Do you know the cause of the Dec 2022 spike, or are you just speculating?

    And do you have numbers available that will allow a proper comparison of excess deaths measured as a number (40,000) and a % (the 19% given for December in the link you gave). You can't compare apples and oranges,

  48. Solar cycles cause global warming

    retiredguy:

    You have linked to the publisher's site, which only has a portion of the paper visible (along with "Access through your institution" and "Purchase PDF" buttons). Google Scholar led me to a full version here.

    The first half of the paper simply reiterates a variety of reasons to expect variation in solar input to the earth system on a variety of time scales, without getting into specific solar irradiance values. They also talk about the importance of spectral variations - in addition to simple variations in total energy input.

    In section 3.1, they cover "the reconstruction of the past solar irradiance". In that section, they state (emphasis added):

    "Our own irradiance reconstruction is based on the frequency of the Schwabe cycle because we find a better fit with the temperature data if we assume a linear relationship between cycle frequency and irradiance (Fig. 7).

    Their figure 7 is a graph of the reconstructed solar irradiance. It shows a solar irradiance value of about 1362 W/m2 in 1850, and a value of about 1366 W/m2 in 1990, for a difference of 4 W/m2. The wiggles in their reconstruction go as low as 1361 W/m2 in 1900, up to 1364 W/m2 from 1920-1950, and down to 1362 W/m2 around 1965.

    Skeptical Science also has another page on "It's the sun". On that page, we see another solar irradiance reconstruction:

    Solar irradiance and temperature

    Note that the reconstruction from the paper you linked to shows much more variability and range. Their figure 7 mentions a "14-y low-pass filter", so it should probably be compared to the 11-year average in the above figure.

    So, the first thing is that they have estimated a much larger change (about 4x) in solar irradiance over the 1850-1990 period than most other sources. This would explain their conclusions that solar forcing is a strong effect.

    So, you have to ask, which solar reconstruction is better? Well, I think the clue is in the section I quoted and highlighted above, regarding their choice of method of reconstruction:

    "...because we find a better fit with the temperature data..."

    To put it bluntly, to claim that solar forcing is an important factor affecting temperature after choosing a solar reconstruction "because we find a better fit with the temperature data" is plain bad science. In all likelihood, they have erroneously fitted other causes of temperature change into their solar reconstruction, which leads to an overestimate of the magnitude and importance of solar forcing.

    I notice their figure 10 is also for northern hemisphere temperature, not global. They do talk about the two hemispheres in the text, but I don't see an explanation as to why they did not use global temperature in their final evaluation.

    In short, the main weakness is that they have a really bad solar irradiance reconstruction.

    Solar cycles cause global warming

    retiredguy... That's a very old paper and really doesn't claim much nor does it seem to present any actual research. I don't see any claim of 40%. Is there more to the paper that I'm not seeing? I ask because the the paper in that link ends with an ellipsis suggesting there's more.

  50. Solar cycles cause global warming

    Can anyone comment on J. Beer et al's assertion in 2000 that 40% of global warming which occurred between 1850 and 1990 was due to the sun ?
