  1. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    scaddenp@9, good points. Isn't it remarkable that the Earth ever so slowly changed over millions of years until we arrived at this delicate position where ice-age cycles took us up and down, cycling between 180m and 60m equivalent sea level rise worth of ice on land. The incredible sensitivity of Earth to the tugs and pulls of Jupiter and Saturn are a true indication of the delicate balance that Earth has functioned in for so long.

  2. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    The milkankovich cycles are only able to force ice ages (and sea level) when GHGs levels are so low that summer insolation at high latitudes doesnt not melt snow. (The milankovich cycles operated long before the Pleistocene ice ages). The simple geoengineering to prevent an ice age is to increase GHG to such a level (around 400ppm) that they dont have an effect. Whoops! we have just done that.

    We definitely agree with Wally Broecker that climate is an angry beast and that we shouldnt be poking it with a stick.

  3. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    Indeed, Evan. That's what I figured. A subtlety in mentioning, without naming, the gravitational effects that might see minor - and are, in a direct sense, based on ubrew12's numbers.

    But those minor direct effects lead to indirect effects, with a well-known and plausible physical mechanism, that make for major shifts in climate.

    A delicate balance for sure. People argue that we don't know enough about climate to be confident that CO2 is having a warming effect - all those pesky unknown unknowns - but we know enough to be confident that geoengineering will be entirely predictable and problem free? Surely a place to be skeptical.

  4. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    Bob@6, correct. These are not tidal forces due to Jupiter and Saturn, but rather complex feedback processes triggered by varying orbital cycles due to the tug and pull of Jupiter and Saturn on the Earth, ala the Milankovitch cycles.

    I did not give a reference because I am simply framing the effects of the Milankovitch cycles in a way that people may not normally think of them.

  5. CO2 limits will hurt the poor

    PollutionMonster @72 ,

    Regarding Kulp & Strauss (2019)  the figure "per satellite measurement" indicated that 230 million people would need to move, i.e. would lose their land, as the sea level rose 1 meter.  Yes, that might well take around 100 years (and the figure might well have grown to more than 230 million by then).   The main point is that the land loss will include a great amount of fertile farming land, including the particularly productive river delta regions.  But I am sure your Denier friend has no concern about loss of food production in a world of increasing population.   Nor will he admit to concern about impoverished refugees coming to a location near him ~ or concern about their wellbeing.

    Yes, in the big picture, it all happens slowly.  I must admit to a certain liking for your Denier friend.  He seems a man without compassion.  The world needs more of that sort of person !

  6. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    ubrew12, Phillippe:

    At a guess, I expect that Evan may be claiming that the variations in the Milankovitch cycles are due to the gravitational effects of Saturn and Jupiter, such that we have glacial/intergalcial periods at 100,000-year intervals. And that causes sea level changes of 120m.

    Just a hunch. Evan can confirm.

    Eclectic @70

    I read your entire post, thank you for the response. :) I feel like I can have a conversation with you on how to best prebunk and debunk climate change deniers. One problem I have is that some websites are so full of snark and dog piling that I am afraid to have a conversation with other climate change activists. That people are trying to look cool and who can get the best insult off, rather than attempt to become better prebunkers.

    According to Greta Thunberg politics have become very very toxic. 

    GretaThungberg NPR

    One dilemma I have with such a strategy is the person practicing denial lures me into the <i>"snake pit."</i> For example if I say the ocean is acidifying, they insist the statement is vague and therefore useless, demanding I say exactly how fast, how much, and what damage.  Ditto, with iceberg shrinking, sea level rise, and refugees.

    Next, if I commit to exact numbers, we enter the snake pit. The cranky uncle comes up with different numbers and shows the flaws of my numbers they call me a compulsive liar and are usually able to swing the audience. I'm suprised how often the onlookers side with denial.

    I am not the most scientifically literate, nor the most intelligent. I often have to admit humility that the denier is simply smarter and more knowledgeable. That they can pull the conversation to the battleground they are most effective at.

    For example when I linked to the Kulp Strauss 2019 article they just dismissed as irrelevant that the sea levels will rise slowly and people will migrate as they always do. Thank you again for the informative civil conversation. :)

    Evan at 3: Do you have a source, link, published paper for this very bold assertion?

  9. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    Re Evans@3.  The gravitational pull of all solar system objects, on Earths surface, relative to the moon is: Moon 1, Sun 0.4, Venus 6E-5, Jupiter 3E-6, Mercury 4E-7, Saturn 2E-7, Mars 5E-8, Uranus 3E-9, and Neptune 8E-10.  

  10. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    Saturn and Jupiter do a dance with the Earth which, over the course of 100,000 years, causes sea level to rise and fall by 120m (400 ft). This demonstrates how delicately balanced our planetary systems are.

    Do humans have any chance of artificially controlling such a delicately-balanced system (i.e., through geo-engineering), short of ceasing to poke a prod the system the way we do?

  11. CO2 limits will hurt the poor

    PollutionMonster @70 ,

    Please do not go down into the "snake pit".  There is no point arguing in areas where you are not clearly the victor.   Whether it is 5 million per year dying of heatwaves versus 2 million dying of cold ~ or vice versa . . . really does not matter, because Deniers will dispute you with all sorts of rubbery figures (faux or real) and their own rubbery definitions of what's what.   You cannot clearly win, in the eyes of onlookers (and they will see you as argumentative & unconvincing . . . and losing credibility).

    The people who spout "freedom / totalitarian control" and suchlike ~ they are a lost cause.   They cannot (and do not wish to) think logically.   They are into Conspiracies ~ the Mr Soros; the Rothschilds (and their space lasers) ; other Billionaire Communists; the Deep State; the "Q" ; the Lizard people ; etcetera.

    Keep it simple.  Point to AGW leading to ice-melting and sea-level rise with consequent migrations of millions of refugees.   And gradual worsening & lengthening of heat waves in India and the Middle East and Central Africa.   More refugees, more poverty, and still more refugees.

    Then the real question for discussion becomes : what should we actually do to reduce & prevent those future problems?  Sit on our hands for the next 20 years?  Or advance gradually (or quickly) toward nett zero carbon emissions (maybe by 2050 or 2060 or 2070?).   Argue for the big picture, not the small stuff.

    It is the same with friends who are "un-engaged"  ~ just make an occasional brief reference to what we actually need to do.   (You don't want them to think of you as That Guy  who is a boring one-trick pony.)

    nigelj: At this moment in time, the human race seems to be caught between a rock and a hard place with respect to mitigating man-made climate change. Sooner or later, something has to give. As someone who turns 80 years old this coming summer, I don't know if I'll live long enought to see which path is chosen.  For my childrens' and grandchildrens' sake, I sure hope its the right one.

  13. 2023 SkS Weekly Climate Change & Global Warming News Roundup #8

    Regarding the engineered solutions to humanities various problems. I acknowledge the downsides of this and I oppose geoengineering the climate, but I get tired of listening to academics (and the general public) potificate on the dangers of engineered solutions, while they fly around the world and live in their homes packed full of technology and drive their sophisticated cars. If its really a huge problem, wouldn't they set an example and live simply?

    BaerbelW @68

    I am checking out the link you posted. Specifically the one page Flyer.

    One page flier

    I find the part about the part about ask for the sources of their information to lead my friends to either avoid the subject or clam up. I've found my friends to either talk way too much and not give me a chance to talk or avoid the subject entirely. Feast or famine neither feels like a real conversation.

    Right now I am more concerned about stopping myself from spreading misinformation. For example I recently got called out online for spreading misinformation and labeled a liar and a science denier when I said there was five million people dying a year from climate change. I get confused by the scientific jaragon that the lancet used the word association.

    This sometimes spills over into other areas like how many people die from covid-19, or smoking and comorbidities. Seems the theme is to say yes, climate change exists, smoking causes cancer, covid-19 kills, but the damage is minimal and we should sit on our hands and do nothing.

    Followed by a verbose speech about freedom and analogies to totalitarian regimes. Anyways, seems the fastest way to lose your audience and interlocutor is to accidentally spread climate change misinformation.

    CO2 limits will hurt the poor

    PollutionMonster and Others,

    The post that BaerbelW @68 linked to is an excellent and comprehensive reference guide.

    I would add that it is important to understand that many difficult interactions are essentially “Conflicts of Interest”. And they can only be resolved if there is an agreement regarding the objective.

    As an engineer I learned that there are a diversity of acceptable ways to achieve an objective. The key is alignment regarding the objective. And the most essential objective is ‘minimizing harm done and minimizing risk of harm’ while developing improvements for the benefit of Others. If you are unable to establish alignment that the objective is the evidence-based pursuit of that objective there will be no ‘alignment on the acceptability of desired actions’.

    For engineered structures there are a diversity of materials and types of structures that will be acceptably safe. The problematic conflict of interest is not the choice between comparably safe solutions. The problem is a desire for an alternative that would not be as harmless or safe. Cheaper, quicker, easier, and more profitable alternatives are often more harmful or less safe. So pursuit of any of those ‘objectives’ can create a harmful conflict of interest.

    A final point. When the person you are dealing with tries to change the topic, because their original desired thoughts are not consistent with an evidence-based understanding of how to limit harm done and help others, try to remain focused on the original issue rather than be distracted by ‘the new alternative thoughts’.

    One on one discussions with friends and family members can make sense but are obviously not easy. If you want to tackle them, please check this blog post about a neat communications flyer with tips on countering conspiracy theories and misinformation.

    Rob Honeycutt @64

    Yes, I agree with what you are saying. Even real life friends it seems that the one versus one conversation seems pointless. The chances of changing their mind is maybe 1%.

    As for others being interested in the science. I do know depends upon the forums. Some places it just seems like who can do the best job of a gish gallop of ad hominems, strawmans, and false accusations win. Do I defend myself or just stick to the science?

  18. One Planet Only Forever at 05:37 AM on 24 February 2023
    CO2 limits will hurt the poor

    Re my comment @65,

    I should have included the following reference:

    RateHub "What is the total cost of ownership for a car?"

    The RateHub evaluation includes costs excluded from CPA Canada link I provided @65 (which is largely based on, and refers to, the CAA's Driving Cost Calculator).

    The RateHub evaluation includes consideration of things like parking costs and seasonal tire change-over.

    And there are other costs to consider like new tires every 5 or 6 years. And a big cost that is not in the evaluations is unexpected repair costs (not part of the planned regular maintenance).

  19. One Planet Only Forever at 04:01 AM on 24 February 2023
    CO2 limits will hurt the poor

    As Rob says @64,

    In many cases a person may not admit to changing their opinion n an on-line back and forth, or a personal discussion. However, they may ultimately alter their thinking based on the interaction. But, in some cases, they will just alter onto a different inexcusable unjustified attempt to excuse or justify their developed liking for benefit from fossil fuel use.

    It may help to share something like the following article from CPA Canada (Chartered Professional Accountants Canada). It lays out the cost facts about car ownership:

    First-time car buyer? Here’s what you should be budgeting for.

    That indicates that owning a small basic car costs about $1000 per month in Canada. And the type of vehicle (electric vs fossil fuel) would not make much of a differnce. Higher up front cost of an electric is offset by lower maintenance and lower fuel costs.

    Bottom line - Car Ownership will always be a crippling expense for middle income and poorer people.

  20. CO2 limits will hurt the poor

    To add to OPOF @63... The first task for yourself is accepting you will never change that person's mind. Once someone has taken a firm position, as they seem to have done, it is virtually impossible to alter their base conclusions. In fact, they will become more intransigent over time.

    If you're engaging with them one-on-one, the exchange will be a rather pointless task, other than what you may learn, yourself, through debunking myths. If you're engaging in a public forum, try to remember the other people who may be reading. There you might find minds that can be changed and people interested in the science.

  21. One Planet Only Forever at 00:03 AM on 24 February 2023
    CO2 limits will hurt the poor

    PollutionMonster @60,

    The 'car' issue could be directly addressed.

    Start with: AGREE with the person you are dealing with - Needing to own and use a vehicle is a very expensive requirement. It is a very "high cost of living" item faced by the poor.

    Then address effective solutions to that problem: Reducing the need for a personal vehicle. Bike lanes can be part of the solution. And improved and lower cost public transit is also helpful. (Note that making harmful fossil fuel cheaper by not requiring the effort and cost of making it 'harmless' to be paid is not a solution - It is the origin of the problem. Fossil fuels always should have been much more expensive)

    AGREE that a lack of use of Bike Lanes may indicate other systemic problems that need to be addressed to make it easier for poor people to live 'without a car' and with the freedom they can have by biking when the weather is not horrendous (when public transit would be the better option).

    AGREE that helping the poor should not be "Paid for by the poor".

    Some of those points or ways of presenting the case may apply to the Solar issue.

    John M @ #2:

    Taking into account what you said, I would bold the titles of the two books and put the date of publication for each in parenthesis immediately after the title. Doing so would let the reader know how old the books are.

    I apologize that the inflammatory labels were too much, sorry you had to edit. Thanks for letting me know to keep the inflammatory labels down a bit. Still new here, I want to respect the rules, but gonna stumble some at first.

    Rob Honeycutt @61

    Thanks for the quick response. I want to focus on solar panels. That seems to be what the proverbial crankyuncles that I run into seem to be mentioning the most. I will put in fact, myth, fallacy, fact format a debunking. Though right now i don't have the scholarly peer reviewed articles to back up my conclusions.

    Fact: Solar panels are a cheaper energy source than fossil fuels.

    Myth:  CO2 limits in the form of Solar panels will hurt the poor of the first world.

    Fallacy: Cherry picking by using old data and omitting fossil fuel subsidies that can be used on clean energy. Hidden costs like healthcare and future generations having to clean up costs of pollution select evidence is used to come to the faulty conclusion.

    Fact: Solar energy is cheaper than coal.

    Analogy: Pretending that solar panels are still expensive is the same as imagining that all cell phones are still huge bricks.

    Sources: NPR, Nature, and popularscience.

    Solar cheaper than Coal NPR 2020

     Popular science solar panels got cheap, 2021.

    Nature 5.9 trillon fossil fuel subsidies.

    Let me know if there is anyway to improve this debunking, and of course I would appreciate a fact check.  The skeptic looks bad when the person who is denying climate science can prove them incorrect. Hopefully this is the correct thread to post this comment, seems the best to me, but I could be wrong. Thanks in advance. :)

  25. CO2 limits will hurt the poor

    PM @60... Sounds like your climate denier needs to pick a lane (pun intended) and stick to it rather than Gish galloping through all the topics they don't understand.

    CO2 limits will hurt the poor

    I could use some help I got a sanctimonious belligerent trollish climate change denier [snipped] scolding me for not caring about the poor in first world countries. They won't even tell me what country they are from.

    They go on and on about bicycle lanes not being used and how the working class has to pay for them. That lashing rain, what in the world is lashing rain anyways, makes it too difficult to bicycle to work?

    Then, they go on and on about the expense of electric cars and solar panels. I've found the electric car and solar panel argument to be very common.

    Crank uncle: Electric cars and solar panels are too expensive for the poor!

    Thank you in advance. :)

    Moderator Response:

    [BL] Please keep the inflammatory labels down a bit.

  27. At a glance - What were climate scientists predicting in the 1970s?

    I kinda agree with that, John. Italics are typical in most media outlets. However, you'd do well to find second-hand copies of the books mentioned in this case since they were published almost 50 years ago.

    In the at-a-glance versions we avoid all things that could distract the reader: a link may break the flow of concentration as someone stops to think about clicking it or not. These are after all aimed at being inclusive and hopefully should be understandable to folk regardless of previous experience (or not) in the sciences.

  28. At a glance - What were climate scientists predicting in the 1970s?

    John Mason & Baerbel:

    I suggest a protocol be adopted to bold the title of all books (see second paragraph of OP) and embed a link to a publisher and/or online seller of the book into the title of each book.

    I also suggest a protocol to use italics for the title of all published papers (as was done in the third paragraph of the OP) and embed a link to the journal in which the paper appears.

    That's an awesome example. "I don't deny the Earth has a climate." I love it! Thank you. :)

    Thanks this helps me a lot.

    ""Denier" is a handy short label for those who are opposed to taking action for fixing the global warming problem. They themselves dislike it, and whinge greatly about the label"  Eclectic

    I won't visit or even mention the name of the website you mentioned. I figure it is just giving them more ad revenue. As for the part about Africa, I call what the climate change denier is doing as concern trolling. This argument also relies heavily upon climate myth #3 it is not bad.

    Sometimes the denier takes the moral grandstanding route, angry, and insulted when I implied they are a climate change denier. I usually, just apologize to be nice, but sometimes I think I apologize too much. Anti-vaxxers do this too.

    Caricature of a climate argument.

    me: "climate change can be prevented without pitting the enviorment versus poor people. I recommend the websites skepticalscience.com and crankyuncle."

    Sample denier argument: "You are calling me a climate change denier by linking to the two links above. How dare you insult me! Calling me a climate change denier is an ad hominem and dehumanizing language. You should be ashamed of yourself. I will not stand for such harassment, abusive hate speech, I am highly offended!!!"

    This moral outrage type of argument can be quite difficult to stomach. More so if they catch you off guard. Let's check my message, wait what? Let alone if I show any emotion especially anger.

    me: "Wow, this is tin foil hat level of conspiracy thinking gish gallop."

    Climate change denier: "Enough with the attitude! I wrote twenty pages and you dismiss my claims with a single sentence. You ignore all of my claims and make no effort. What do I get in response, snark? I find this disrespectful. Nobody listens to me. How dare you! "

    Pay attention to the self-pity in the above paragraph. I can practically hear them playing a violin.

    With your example of Africa the climate change denier tries to peg the skeptic as a member of the cabal, the denier as a member of the army of light, and everyone else as sheeple. That's why I think #3 its not bad is such an important myth to dispel.

    The idea that proponents of climate change action are cast as the villains and deniers the heroes bothers me. Taken a step further the climate change denier sometimes resorts to abusive ad hominems and even threats. Justifying their nasty remarks and threats because in their warped sense of reality they are heroes defeating a horrific villain and saving the sheeple.

    I call the tactic attack the skeptic. Sometimes I get a little scared when a denier uses violent rhetoric and graphic threats. At first I thought it was funny because it was so over the top. I though he was just poeing to be funny.

    Poe's Law

    https://rationalwiki.org/wiki/Poe%27s_Law

    Pretty scary because this has been going on since about May 2022, I though if I ignored him he would just go away.

    But I guess that's pretty normal if you debunk climate myths long enough you are going to attract a tin foil hat Young Earth Creationist Christian zealot who really thinks God is on their side believes in Qanon and views the opposition as a satanic threat. How common is this?

    In conclusion, I think #3 myth it is not bad is a pretty good place to focus because climate change deniers love to declare themselves the heroes and vilify anyone who pushes climate change action.

    Simplest form:

    Climate change action advocate: "We should do something about climate change."

    Denier: "You monster! Groups x,y, and z will be harmed by your immoral and reckless actions. We should be completely passive and do nothing because climate change is good."

  31. It's not bad

    "It's Not Bad" is quite a general topic, and covers many Denialist areas.

    "Denier" is a handy short label for those who are opposed to taking action for fixing the global warming problem.  They themselves dislike it, and whinge greatly about the label : but after all, a label usually doesn't matter much ~ since every reasonable person can recognize an alligator / crocodile / caiman by sight, regardless of its exact label.

    No point in joining the bunfight at the famous blogsite WattsUpWithThat.   WUWT is 98% echochamber, and shows the interesting range of deniers ~ extending from the studious intelligent ones who are crippled by their own motivated reasoning . . . to the crackpots who deny CO2-physics and/or deny there is any true warming occurring.  And through to the paranoid political wingnuts who deny any AGW (or alternatively, claim that AGW is good for us and we should have more of it).

    At WUWT  there is a kaleidoscopic churning of all sorts of "reasons" why we should stay on fossil fuels and avoid renewables.  #Now, during the past decade (as car lithium batteries have soared in number)  WUWT  has ranted about the need to increase coal usage to: "lift those poor Africans out of poverty" . . . and even more particularly: "EV batteries are causing small Congolese children to work in slave-like conditions in the cobalt mines".

    The "poor Africans" argument I find remarkable, as it typically comes from American wingnuts who oppose any decent governmental help to their own American poor ~ and who themselves for the past half-century have have not lifted a finger personally to aid the African poor.  And even now they still do nothing to help these children ~ and they completely fail to see that it is sheer poverty which forces African parents to send young children to the mines.  Fixing the Root Cause is unthinkable.

  32. It's not bad

    PM @411...  Many who claim not to be a climate denier are merely stretching the definition to make that claim. As in, "I don't deny the earth has a climate." And then if you point out the absurdity of that definition and clarify they're a climate change denier, they respond with, "But I don't deny that the earth's climate changes; in fact it's always changing."

    Now, I generally try to skip all the inanities and go straight to the full scientifically accepted definition that... human activities, primarily through the burning of fossil fuels, are responsible for most or all of the warming of the past 50 years and best estimates show the earth will warm ~3°C per doubling of CO2 concentrations

    If they deny that, they're a climate denier. Plain and simple.

  33. PollutionMonster at 11:08 AM on 21 February 2023
    It's not bad

    Eclectic @410

    Right now I am talking with a person who's position is ambiguous. The individual claims they are not a climate denier. Yet, they make many of the denier's talking points. Similar to dog whistling. My guess is they are a climate change denier, but won't admit it.

    Instead, hiding behind how much the "working class" is harmed by "rip off merchants". Sample argument below:

    "But I'm not a Trump supporter or a climate change denier I'm concerned about costs to the working classes you claim you are also yet you sound exactly like one of the rip off merchants who feign concern over the planet yet profit significantly from forcing people into green schemes they cannot support, you have no explanation on how it's in anyway reasonable to expect people to pay for electric cars or solar panels, you also want to punish them further by insisting they cycle long distances to work in every sort of condition." sample probably climate change denier argument

    This seems like classis motte and bailey strategy to me. My advice to you is push a little further than you feel comfortable into the innermost motte by pushing climate change action. Giving no place to retreat, this advice is from the skeptics guide to the universe book by Steven Novella, MD.

    I've found very few climate change deniers will straight out deny warming. Instead, hiding behind more "moderate" stances. The result is the same whether a hardcore or moderate denier, slothful climate action. Anti-vaxxers do the same, "I'm not anti-vaxx I am anti-mandate and mask".

    I. Ban Gasoline leafblowers. One of my favorites to show climate change mitigation can be very small. Many people want to get rid of them anyways.

    II. Transfer fossil fuel subsidies to renewable. Showing the true cost of fossil fuels.

    I think you are 100% correct about persuading the onlookers. Good points on A, B, and C I will try them. C seem very interesting the part about denialists hating the idea of refugees and migrants. :)

    The Problem with Percentages

    Evan,

    I think it would help to insert points along the line of your earlier post about the importance of watching the Keeling Curve for evidence that efforts to reduce climate impacts are being successful.

    Examples of the type of items to include would be trends of:

    • Fossil fuel consumption (burning of coal, oil, nat. gas)
    • CCS on fossil fuel use (the short-term helpful reduction of Carbon emissions)
    • CCS from the atmosphere (the CCS that needs to be developed)

    And the future of the trends should only be speculated about based on evidence of effective helpful transitions of social drivers as presented in the Hamburg Climate Futures Outlook: The plausibility of a 1.5°C limit to global warming - social drivers and physical processes (Story of the Week in the 2023 SkS Weekly Climate Change & Global Warming News Roundup #5).

    And the severity of the challenge can be highlighted by examples like the massive new coal plants in South Africa that are planned to be operated until the 2070s.

    Blooberg report: Giant New Power Plants Undermine South Africa’s Emissions Pledge

    Who will pay to compensate the investors and South Africans for their lost opportunity to profit and benefit from these facilities for 50 years?

    That is an absurd question. The people who made a bad bet should lose their bet. But all the people making Bad harmful bets know that the history of humanity is loaded with examples of wealthy people, and powerful large groups of people, being well compensated when they lose an opportunity to benefit from being harmful to Others (because they won't stop being harmful until they feel they are adequately compensated for not being allowed to continue believing and doing what they developed a liking for).

  35. The Problem with Percentages

    Michael Sweet@28, I am not suggesting that renewables will replace fossil fuels instantly. Rather, when the NYTs report impressive-sounding renewable-energy growth numbers, I want the readers to put those number into context and not get lulled into a false sense of success. We have a long way to go, and we need the readers to know that ramping down fossil-fuel use will not occur quickly, nor will it occur without putting pressure on governments. Regardless of how cheap renewables are, there is likely to be active lobbying for years to come to sustain the fossil-fuel industry. You note the we all need to work harder to get governments to stop subsidizing fossil fuels. I agree. We need readers to help apply pressure through their votes. What I want them to know is that although the renewable revolution is getting going, we are a long way from where we need to be and we need their help to get where we all want to be.

    I will consider your's and all of the other comments in the rewrite. I am not trying to contribute to doomerism. Just trying to make sure people understand the full scope of the problem, because there is no time to waste in continuing the transition from fossil fuels to renewable energy.

  36. The Problem with Percentages

    I am sorry, FIgure four shows 14,000 TWh of energy, similar to the IEA.  I have difficulty reading series of zeros.

  37. The Problem with Percentages

    Evan,

    Renewable energy has only been the cheapest energy for about 5 years.  For the first couple of those years renewables were only a little cheaper than fossil fuels and there were many locations where fossil was still cheaper.  Now renewables are the cheapest everywhere.   It takes 5-10 years to build most fossil plants.  It takes years to build the factories that manufacture the panels and turbines for renewable energy.  Your expectation that renewables will replace all fossil fuels instantly is misplaced.

    We all need to work harder to get governments to stop subsidizing fossil fuels and make it easier to install renewabes.  Environmental doomerism turne people off so that they do not take the actions necessary to turn the ship around before it hits the iceberg.

  38. The Problem with Percentages

    Michael Sweet@26, you note,

    "The claim that renewables can only generate 30% of all electricity was shown to be completely incorrect years ago."

    I am not saying that renewables cannot generate more than 30%. I am saying that going beyond 30% on an annualized basis is difficult and will likely require storage. Figures that show renewables generating in excess of 30% on an annualized basis are, to my understanding, based on relatively short-term events and not averaged over an entire year.

    I am not trying to propogate doomerism. Rather, I am trying to convey to the readers the task that lays ahead if we are to meet the goals of the Paris Accord. You note yourself the headwinds we face ramping down fossil-fuel use. Yes, I made a mistake in my analysis summarized in the first comment, and I will correct this. I will refine the rest of the text. But the main conclusions remain. Getting renewables to the point where they begin to supplant, and not supplement fossil fuels is still ahead of us and will not necessarily be easy. I read your comment as saying essentially the same thing.

  39. The Problem with Percentages

    Doug,

    I saw the reference.  The entire point of the OP is derived from figure 4  which is the construction of the author and has no reference.   Others have  pointed out why this figure is not even wrong.  According to the IEA report, global electricity demand will be approximately 29,000 TWh in 2025 not the 160,000 TWh shown in figure 4.  It appears to me that the author has added a factor of ten to the world energy demand which makes it appear that renewable energy cannot replace fossil fuels.  I note that checking the carbon intensity of the EU would immediately show that renewables have significantly reduced the amount of carbon released.

    It appears to me that MA Rodgers analysis of figure 4 is correct.  Wind and solar energy, especially solar which is the cheapest energy in the world today (only wind can come close to solar), are increasing exponentially.   Averaging in hydro, which for all practical purposes has not significantly changed in the past 10 years, makes an exponential increase turn into a small increase.

    In the OP it states "it is very difficult, without using energy storage, to generate more than about 30% of the energy from renewables."  In comment 8 says " Any of these projections are risky, because continued expansion of renewables beyond producing about 30% of power requires storage technology that must be deployed on a large scale and may compete for materials used in the transportation industry."  The published literature has analyzed this and there are sufficient materials for the foreseeable future available.  There are bottlenecks that have to be overcome as more renewable energy manfacturing facilities are built.  The claim that renewables can only generate 30% of all electricity was shown to be completely incorrect years ago.

    The International Energy Agency report that I cited covers the entire globe.  I used USA data to address the 30% claim because the data was the first hit on my Google search and met the criteria of wind and solar only.  It takes some time to find renewable energy data where the hydro has been left out.  The 30% claim was made without any supporting data.  Data proving the 30% claim is false anywhere shows the 30% claim is false for the entire world.  

    The OP is terrible doomerism.  The IEA data clearly shows that wind and solar currently replace essentially all of the increase in energy demand worldwide.  The question is: can the installation of wind and solar increase fast enough to meet climate goals.  Last year over $1 trillion (!!!!!) was spent by governments to subsidize the fossil fuel industry and only about 1/3 of that was spent (primarily by the free market) on building new renewables. How can the politics be overcome?  

    Renewables including storage are much cheaper than fossil fuels.  In addition, fossil pollution kills over 5 million people every year worldwide.  Switching to renewables will make everyone healthier because ofreduced pollution.  It has been shown that even 2% of EVs replacing internal comustion engines results in less hospital visits for asthma.

    The Paris accords could still be met if most governments worldwide subsidized renewable energy as much as fossil fuels.

    The OP should be removed from Skeptical Science since the conclusions are false.  It will be used as an example of environmental doomerism.

     

  40. The Problem with Percentages

    Ubrew12, PrzemStep, and Michael Sweet. I placed a green-box message at the start of this post noting the error in my analysis and also noting that I will be redoing this post. Thank you for your comments and for helping maintain the high-quality readers expect to find at SkS.

  41. The Problem with Percentages

    Michael Sweet, thanks for your comments. As ubrew12@1 pointed out, I did not properly account for efficiencies in comparing electric generation from fossil fuels to determine, as you also point out, that renewables are expected to cover the growth in electric energy demand over the coming years. Others here have pointed out other analysis they would like to see in such a post. I will be redoing this post to clean up the points everyone has made here. As much as it hurts to be reminded of weaknesses in my analysis and writing, I will correct them.

    None of this will change the basic points of this article, however, that percentages can hide real trends, and that renewable energy has yet to replace fossil fuels in any significant amount. Don't expect the fossil-fuel industry to just let that happen without a fight. One of my purposes in writing is to help the reader see the true magnitude of the problem we face so that they can properly gauage their response when they decide what to buy, and how to vote. Renewables meeting growing electric energy demand, instead of only 30% as I noted, may be a good thing in terms of our progress towards ramping down fossil-fuel use, but it is not a reason for too much celebration if we are to meet the objectives of the Parid Accord. We must do much much better. I want readers to be aware that we've done the easy work with renewables, and that what comes next will likely be much harder.

    So thanks all for your comments. I have work to do to rewrite this paper. I will try hard to regain your respect with the rewrite.

  42. Skeptical Science New Research for Week #7 2023

    Thanks for making those excellent connections, OPOF, particularly forming the deep connection between Cameron & Carter's report and the HCF 'how are we doing?" cold bath.

    The Hamburg report is something we naturally want to turn away from, perhaps because it bolsters what for many of us has become more than a sneaking suspicion. 

    As we pointed out last week (?) when we featured it, it does hinge on a stipulation that is not even at this late date set in stone: "given the observable trajectories of social drivers." I wish we could feel more optimistic that we were collectively at the wheel and driving our society with a shared map. 

  43. The Problem with Percentages

    Although they're not obvious, Evan's data sources are in the figure captions for figs. 1-3. Although OWIND is not specialized along the lines of IEA or the like, it's not pitching data ideally suitable for producing "industry propaganda." OWIND's renewables projections seem to be substantially (for the precision required here given Evan's thrust) in agreement with the IEA, which admittedly have been conservative (as has been so much else assessment in this rapidly evolving scene). 

    This brings us to figure 4, which shows quite a bit of daylight betwen overall demand increase and the contribution of renewables to that— back to the point Evan is making about percentages. 

    Michael, using the conservative IEA source (it's better to pick one, and IEA seems to be a benchmark for most discussion) and so that we can better understand: do you think the overall demand projection in fig 4 is incorrect, given that the renewables portion appears largely commensurate with IEA's projection?

    I think Michael may have been typing in haste and dropped a clause when he wrote "Likewise your claim that renewables cannot generate more than 30% of all electricity was proven incorrect over 5 years ago when several countries exceeded that amount," because Evan did not make that claim.

    Also and notably with regard to the latter remarks, Evan's analysis is speaking of global energy demand, supply. It's not an apples-apples critique to employ a handful of wind-heavy US states to form a comparison with what's under discussion, the global situation. Not saying Michael's wrong, but it would be better to employ broader geography— the same whole globe that is the subject of Evan's analysis. Otherwise we're talking about quite different things.

    I'm pretty sure that whatever misunderstandings there are over this can easily be resolved with some collaboration. It's possible that Evan is wrong. That can more easily be established in an atmosphere of calm. I feel certain Evan would be fine with making his analysis better if such is shown necessary. Probably a good step would be to agree on data sources, make sure the subject being discussed is the same, and that what Evan is claiming is clearly understood.

  44. Skeptical Science News: The Rebuttal Update Project

    I am pleased to report that there are countervailing forces to "Citizens for Responsible Solar" (see #13) and their ilk in the development of solar energy in the US. A major development is explained in the following article:

    Public Lands in the US Have Long Been Disposed to Fossil Fuel Companies. Now, the Lands Are Being Offered to Solar Companies by Wyatt Myskow, Clean Energy, Inside Climate News, Feb 19, 2023

    The lede for this story:

    As the nation looks to transition to more forms of renewable energy, the country’s millions of acres of public lands could be key, drawing concerns over how local habitats could be impacted.

    The folk at "Citizens for Responsible Solar" must be crapping in their kinckers,

  45. Skeptical Science News: The Rebuttal Update Project

    Excerpted from the NPR article I cited in #12:

    "I think for years, there has been this sense that this is not all coincidence. That local groups are popping up in different places, saying the same things, using the same online campaign materials," says Michael Burger, executive director of the Sabin Center for Climate Change Law at Columbia University.

    Citizens for Responsible Solar seems to be a well-mobilized "national effort to foment local opposition to renewable energy," Burger adds. "What that reflects is the unfortunate politicization of climate change, the politicization of energy, and, unfortunately, the political nature of the energy transition, which is really just a necessary response to an environmental reality."

    Citizens for Responsible Solar was founded in an exurb of Washington, D.C., by a longtime political operative named Susan Ralston who worked in the White House under President George W. Bush and still has deep ties to power players in conservative politics.

    Just like Big Tobacco, the Fossil Fuel Industry will never throw in the towel and cease to spread pseudo-science poppycock designed to halt the growth of clean energy.

  47. The Problem with Percentages

    This blog post is over 10 years out of date.  It should be removed from Skeptical Science.  It contains no references to support the absurd calcualtions and conclusions.

  48. The Problem with Percentages

    Evan,

    Your article on renewable energy is so bad that it is not even wrong.  Your claim that rneewables will only generate 30% of new demand for the next decade is simply fossil propaganda.  The IEA released their Electricity Market Report for 2023 on February 8.  Carbon Brief has a summary of the IEA report here.  According to Carbon Brief:

    "Carbon Brief analysis of the IEA figures shows that it expects global electricity generation to rise by 2,493TWh between 2022 and 2025.

    The IEA expects the growth in renewable generation to cover the vast majority of this total, growing by 2,450TWh. This is equivalent to 98% of the overall increase in global demand. my emphasis

    Do you really expect that renewables will replace 98% new energy demand for three years and then they will completely stop building renewables?  Obviously in 2025 the IEA expecte renewables to replace all demand and significant existing fossil power. Obviously after renewables replace all new demand they will begin to replace existing fossil power.  The Carbon Brief article cites several analysis that come to similar conclusions except they have renewables replacing all demand earlier than the IEA.  I note that the IEA has a long track record of underestimating how much renewable energy will be built in the near future.

    Likewise your claim that renewables cannot generate more than 30% of all electricity was proven incorrect over 5 years ago when several countries exceeded that amount.  According to The Motley Fool, using the latest year of data on the USA (fourth quarter of 2021 and the first three of 2022), ten states produced more than 30% of their electricity from wind and solar alone.  3 states produced over 50% and Iowa produced over 62%.   The analysis that I have seen indicate that over 80% of all electricity can be easily produced by renewables using existing fossil peaking plants as storage.  Since new batteries are cheaper than existing peaking plants, Utilities will be building out batteries as fast as possible to save money.

    Your post is a superb example of mathturbation.

    The Problem with Percentages

    Evan,

    I agree with your reluctance to be 'too positive' about the transition away from fossil fuels.

    I have seen many reports indicating successful resistance to approvals of  new electricity transmission infrastructure and new renewable generation facilities. The Story of the Week and first two comments 2023 SkS Weekly Climate Change & Global Warming News Roundup #7   indicate that significant efforts to impede the development of renewable need to be overcome. That will require a significant systemic transition that dramatically reduces the success of efforts to delay the required rapid transition.

    The Hamburg Climate Futures Outlook 2023 that is Story of the Week in 2023 SkS Weekly Climate Change & Global Warming News Roundup #5
    robustly evaluated the current state of affairs and considers it very unlikely that the USA (and many other developed nations) will meet their current Paris Agreement NDCs. And those NDCs that are unlikely to be met are weaker than what is required to limit impacts to 2.0 C.

    The Hamburg Outlook appears to be a more justified perspective than perceptions based on speculation about the continuation of past rates of renewable development. It can be easy to produce a significant rate of increase when starting with a small amount. It is harder to continue that rate of increase, especially when efforts to resist the renewable developments are also increasing.

    One final point ... tragically there is very little discussion and leadership promotion of the benefits of limiting 'unnecessary energy consumption'. Admittedly there are many people who need increased energy consumption to live basic decent lives. But they are not the problem. Their per-capita energy demand will be small. The problem is the high energy consumers who believe that 'More consumption is necessary for them to enjoy their life' and everyone who aspires to develop to be Great over-consumers like them.

    If unnecessary energy consumption was significantly and rapidly reduced the curtailing of fossil fuel use would be more rapid sooner.

  50. It's not bad

    PollutionMonster @409 ,

    Good luck with your battle against the science-deniers.  As you have noticed, they use all sorts of poor logic and see-the-tree-but-ignore-the-forest stuff.  They are emotionally driven ~ as you must be, if you wish to entertain yourself by crossing swords with them in public.

    Your task of course is to persuade the onlookers, not the intransigent Denialists.   My humble advice is to Keep It Simple.

    A/  The observed Stratospheric Cooling is a great argument : being proof that it is not The Sun causing modern global warming.  And the Stratospheric Cooling was successfully predicted by "models" of 80-ish years ago.

    B/  The observed sea level rise is great proof of actual global warming (Denialists try to deflect on to the gray area of "but the rise is not accelerating" or the rubbishy "it's just rebound from the Little Ice Age".)   Also you can mention the coastal measurements by Kulp & Strauss [2019] showing that a 1 meter sea level rise would displace 230 million people (Denialists hate the idea of refugees & migrants).

    C/  When pressed to declare what the perfect climate is ~ I state the climate of 1950 A.D.  (Easy to defend.)

    These sorts of arguments suit my simple brain, and are difficult to counter by sophists, bloviators & other trollish propagandists.
