William at 22:37 PM on 6 April 2024A data scientist’s case for ‘cautious optimism’ about climate change
Nigelj - thank you for your reasonable reply - that did accept the evidence .
So when I look at the big picture there is a strong case to stop greenhouse gas emissions and transition to a new zero carbon energy grid.
Would you not acknowledge that transitioning away from fossil fuels to a different energy form carries some risks in itself ?

William at 22:29 PM on 6 April 2024A data scientist’s case for ‘cautious optimism’ about climate change
This means by 2080 there will be around 12,500 heat-related deaths and 36,500 cold-related deaths.
Firstly it is relatively tiny either way .
2nd - They say without adaption - so in their own terms it will be even smaller.

Echo chambers help no one. People should be brave enough to hear opposing views .

Just Dean at 22:15 PM on 5 April 2024Renewable energy is too expensive
I have now posted a reply to the Energy Bad Boys, EBB , with references to my Notes at Substack that include graphics. Here is a copy of that reply.
--------------------
A thorough review of electricity prices for the 48 contiguous states suggests that there is no correlation between increased use of wind and solar and higher electricity prices. If anything, the opposite appears to be true.
Using data available at the EIA electricity data browser, a comparison of the increase in average electricity prices from 2002 to 2022 for the contiguous U.S. as a function of the percentage of renewable electricity generated suggests that more renewables lead to lower electricity prices, not higher.
A comparison of the retail price of electricity for 2022 for the 48 states as a function of percentage of renewable electricity also shows a similar trend, states with more renewables tend to have lower electricity prices.

Gavin Schmidt has also posted about this over at RealClimate.
In the concluding paragraph:
Remarkably, the Hansen et al projections are basically indistinguishable from what the mean of the TCR-screened CMIP6 models are projecting. Or, to put it another way, everybody is (or should be) expecting an acceleration of climate warming (in the absence of dramatic cuts in GHG emissions)

michael sweet at 02:53 AM on 5 April 20242024 SkS Weekly Climate Change & Global Warming News Roundup #13
Dr Gavin Schmidt published an opinion piece in Nature today. He asserts that the heat in 2023 cannot be explained by known factors. It mentions aerosols, El Nino, the volcano and the items we have discussed. A newspsper article about Gavin's piece quoted Michael Mann as thinking that El Nino was the primary cause of the heat in 2023. Gavin thinks El Nino does not explain the data. I think the blog I linked above puts Dr Dressler in the natural variation group.
It is very interesting to see how this scientific question is discussed in the literature and in the press. Usually scientific issues are discussed primarily in peer reviewed papers. This issue is getting a lot of informal discussion since it is changing so fast. I cannot argue with the likes of Mann, Schmidt, Hausfather and Dressler. Hansen is probably saying I told you so. Chose your own favorite explaination, we will have to wait for more data. On the bad side, March set another huge heat record.

Bob Loblaw at 01:07 AM on 5 April 2024Welcome to Skeptical Science
cookclimate @ 118:
I have looked at the paper in the volume I linked to in comment 121. There are definite changes compared to an earlier version I found that said "submitted to Earth and Space Science", so I presume that you've had some sort of review and modified the paper since the earlier drafts.
It looks like you have identified the 1470-year cycle using your eyecrometer. I see nothing in the paper that actually does any sort of signal processing to identify cycles using any objective statistical technique. You are seeing a cycle because you want to see a cycle.
Your speculation includes arguments that include all sorts of stuff that has been debunked many times before. Pages are available on Skeptical Science that cover thee topics:
- Geothermal heat flux is included in this post.
- The "CO2 lags temperature" argument is discussed here.
- Most of your examples use regional, not global, temperature proxies. Regional temperatures are far more variable than global ones, and it is invalid to compare the two directly. This is discussed in this SkS post.
- You're convinced that an increase in volcanoes are adding to warming. That is the opposite of the argument commonly made by "skeptics" that increasing volcanic activity caused the Little Ice Age, so a subsequent decrease is causing warming (discussed here). In any event, just counting the number of volcanoes (your figure 3) is extremely simplistic. Arguing that more volcanoes implies more geothermal heat is a non-starter, as discussed in the post linked above.
- Your "computer models are unreliable" is an old, tired argument, scoring position 6 on the SkS Most Used Climate Myths. The rebuttal is here.
So, your paper is really nothing more than an "I see it" 1470-year cycle mixed with a rehash and Gish Gallop through a variety of common "skeptic" myths. I could probably find more, but it isn't worth the time.
I hope you didn't pay too much money to get it published.

Bob Loblaw at 11:22 AM on 4 April 2024Welcome to Skeptical Science
Cookclimate @ 118:
Your paper link seems to be broken.
Google Scholar finds multiple links to papers by you with that title, but it's hard to tell if they are all the same paper. Most links seem to be pre-prints, not actual peer-reviewed publications. One of them states that it was submitted to Earth and Space Science in 2020. Another seems to indicate that it was published in late 2023, in Journal of Marine Science Research and Oceanography, which is a title published by Opast. That journal's web page seems to use a DOI: 10.33140/JMSRO prefix, but searching for "Eugene Cook" fails to find the paper.
Opast is listed on Beall's List as a predatory publisher. As such, it appears to have little or no proper review. Can you tell us anything about the efforts you have made to publish your work, and what any reviewers have told you (if there have been any)?
So, by all appearances, you have pointed us to a "paper" that has not been peer reviewed. Perhaps between 2020 and 2023 you had the paper rejected by other journals? And finally managed to "publish" it in a pay-to-play journal?
Anyway, your 1470-year cycle looks awfully close to previous efforts that have identified 1500-year cycles. Skeptical Science has a page that covers this:
https://skepticalscience.com/1500-year-natural-cycle.htm
I'd hate to waste time looking at a pre-print that may have been changed before publication, so if you can properly point us to the correct copy of the paper, that would help.
...and please post anything else on the correct page, linked above. And read that post, and give us some reason why you think that your magical 1470-year cycle is any different from the many other cycles that people have failed with.
Eclectic is most likely correct: your analysis probably has some serious errors.

Cookclimate @118 :-
You are wrong. When the arctic/Greenland ice-sheets melt, that raises the sea level near the equator, and consequently that slows the Earth's rotation. Basic physics. And you are wrong about so very much of the other stuff you posted.
Where do you get all that wrong info from?

cookclimate at 09:28 AM on 4 April 2024Welcome to Skeptical Science
CO2 does not cause Earth’s climate change.
It is estimated that it will cost $62 trillion to eliminate fossil fuels, but eliminating fossil fuels will be a complete waste of our tax and corporate dollars, because it will not stop the warming. You can’t stop Mother Nature.
The IPCC (Intergovernmental Panel on Climate Change) frequently shows that temperature correlates with CO2 for the last 1,000 years as proof that CO2 is causing the warming. But if you extend that to the last 800,000 years, the temperature and CO2 lines do not correlate or fit (Figure 14 in Supplemental Data). If the lines don’t fit, then you must acquit CO2. CO2 is not guilty of causing climate change. CO2 does not control Earth’s temperature. The IPCC has not demonstrated any scientific evidence that CO2 controls Earth’s temperature (they only have unproven theories).
The facts:
• Earth is currently warming (it is still below the normal peak temperature).
• CO2 is increasing (it is above the normal CO2 peak).
• Earth’s current warming is being caused by a 1,470-year astronomical cycle.The 1,470-year astronomical cycle warms the Earth for a couple of hundred years and melts ice sheets primarily in Greenland and the Arctic. It has repeated every 1,470-years for at least the last 50,000 years. It is normal that it would be happening again. It accelerates Earth’s rotation, stopping length of day increases (Figure 9). It warms the Earth. Based on historical data, the current warming should peak near the year 2060 and then it should start to cool.
For more information, see A 1,470-Year Astronomical Cycle and Its Effect on Earth’s Climate,

Jimsteele @97 / 98 :-
John Mason is quite correct, in that the SkS website is open to all-comers. And so, unsurprisingly, as you gaze around the threads, you will occasionally see comments by climate crackpots who have delusional unscientific fixations and who are impervious to reason and scientific facts ~ whereas, at the WUWT website, those sorts of commenters come in droves. (Indeed, they are the 95% majority there.)
But at SkS , you need to comply with the very reasonable rules of posting ~ and you should provide rational fact-based discussion, not pseudo-science & repetitive ranting.
Jimsteele, you have some serious work to do, to reconcile your self-contradictory statements.

John Mason at 08:16 AM on 4 April 2024Climate - the Movie: a hot mess of (c)old myths!
Jim, which is it to be?
"But truth is I have never denied the greenhouse effect."
"Clearly commneting here on SkS is a privelege only given to those who support the CO2 warming narrative."If you have never denied the greenhouse effect, you must surely accept that enhancing its intensity warms the planet. Likewise you must surely accept that reducing its intensity cools the planet.
Both, I must add, based on very old, tried and tested first principles.
There are as we all know other factors that should be taken into account at all times. We are talking about one component, albeit highly significant, of the climate system here.
So I suggest you try and reconcile the two statements above, upon which I have quoted you. -
jimsteele at 07:54 AM on 4 April 2024Climate - the Movie: a hot mess of (c)old myths!
I would respond to Charlie_Brown and Eclectic, but the moderator will simply remove my comments that refute your comments. Clearly commneting here on SkS is a privelege only given to those who support the CO2 warming narrative. Allowing scientific debate is not something that is honored here as revealed by the "moderator" deleting my post on polar bears, and other trivia. WUWT is clearly offtopic, but is always allowed because it dishonestly trashes skeptics which is the mission of SkS.

Scaddenp @94 :
Thanks for that. What a surprise. Actually, I don't remember seeing Jimsteele's name among the WUWT comments . . . but the WUWT commentariat has a cast of thousands . . . and memorywise I might well be developing some Fronto-Temporal Dementia (sadly, one of my bigly favorite rightwing politicians is showing early signs of that condition. Stay tuned ! )
And perhaps my memory was influenced by Jimsteele saying that every skeptic he knew totally understands the greenhouse effect . . . but that quote would be incongruous with Jimsteele being extremely familiar with WUWT, don't you reckon ?

nigelj at 05:10 AM on 4 April 2024A data scientist’s case for ‘cautious optimism’ about climate change
William @ 38
"At what point - would you start to not trust a climate alarmist - if deaths continue to fall or not rise for another 40 years - would you think maybe we should not trust those who make these predictions and fuel the narrative. Or do they just get a forever pass - and you will always accept more predictions - even though the people and movements who made them before have always been wrong."
Scientists are making the best predictions and projections they can. The best evidence they have says heatwaves have already become significantly more frequent and intense (refer last IPCC report), and that this situation will get worse over time particularly as warming gets above 2 degrees C. I see no reason to doubt them. The predictions are rational, logical and evidence based. I am a sceptical sort of person but Im not a fool who thinks all predictions should be ignored or that everything is fake or a conspiracy.
Scientists generally predict heatwave mortality will increase and be greater than reducing deaths in winter due to warmer winters, as per the reference I posted @34. What scientists cannot possibly predict is what advances there might be in healthcare and technology that might keep the mortality rate low. All we know is there will likely be further improvements in healthcare and technology, but quantifying them is impossible and it would be foolish to assume there will be massive improvements. We have to follow the precautionary principle that things could be quite bad.
If warming over the next 20 years causes less harm than predicted mitigation policies can be adjusted accordingly. This is far better than just making wild assumptions that global warming would be a fizzer.
Please appreciate that contrary to your comments elsewhere, multiple climate predictions have proven to be correct. Just a few examples:
theconversation.com/20-years-on-climate-change-projections-have-come-true-11245
www.politifact.com/factchecks/2022/oct/25/charlie-kirk/many-climate-predictions-do-come-true
"I think people just want to believe things will be terrible and there are primed believe end of days narratives."
Some people yes. Other people think things will always be fine. Both are delusional views. I would suggest the vast majority of people between those extremes have a more rational, nuanced view and that they look at the overall evidence. Polling by Pew Research does show the majority of people globally accept humans are warming the climate and we need to mitigate the problem.
"Yes - anything could happen in the future and deaths and damage levels could rise again- but it is nor healthy to ignore the present - or trust people that wilfully distort it."
I'm not ignoring the present or past. The mortality rate from disasters has mostly fallen over the last 100 years and that looks like robust data. I didn't dispute this above. I dont recal anyone disputing it. However you cant assume that trend will always be the case. The climate projections show deadly heatwaves are very likely to become very frequent and over widespread areas, and so obviously there is a significant risk the mortality rate will go up.
It's almost completely certain that at the very least considerably increased resources will have to go into healthcare, air conditioning, adaptation, etc,etc. This means fewer resources available for other things we want to achieve in life. Once again its not all about the mortality rate per se. So when I look at the big picture there is a strong case to stop greenhouse gas emissions and transition to a new zero carbon energy grid.
Moderator Response:[BL] Please exercise restraint in responding to William. Think about whether this actually advances the discussion, or merely starts another spin cycle on the washing machine.

Eclectic at 05:09 AM on 4 April 2024Climate - the Movie: a hot mess of (c)old myths!
Gentlemen ~ "Climate The Movie" is currently being featured and featured "bigly" , at the WattsUpWithThat [WUWT] blogsite. WUWT has the topic "pinned" for consideration and comments. Comments are currently numbering 422. Yes, 422.
However, please do not waste your time by seeking through the 422 for any sign of perceptive & intelligent comments. I assure you that I have skimmed the 400-ish . . . and it's merely the typical WUWT "usual suspects" who are angrily venting into the WUWT echochamber.
Jimsteele , it sounds like you are completely unfamiliar with the WUWT website. It is full (well ~ at the 95% level) of commenters who deny the greenhouse effect ~ either directly or indirectly. Yes, I view the website to "educate" myself . . . mostly about the follies of Motivated Reasoning which are on display there daily. WUWT manages to be both interesting and tiresome. But the cynical reader will see some amusing comments there ~ of egregious fatuities & unintended ironies.
Jimsteele @91 ~ please go back and carefully re-read my comment @84. No, I did not state or allege that you "denied the greenhouse effect". But among your convoluted statements on ocean warming/cooling, you both allege and imply that CO2 contributes little or nothing to the (presently unfrozen) temperature of the Earth's ocean. Do you see the irony/incongruity of your position ?
-
Charlie_Brown at 05:02 AM on 4 April 2024Climate - the Movie: a hot mess of (c)old myths!
The discussion of the heat transfer mechanisms at the ocean’s surface is irrelevant for understanding the mechanism of global warming caused by increasing greenhouse gas emissions. It neglects infrared radiant energy emitted from the surface and the overall global energy balance.
jimsteele @91 claims that he does not deny the “greenhouse effect”, yet the movie and his initial post @67 direct to myths about “global warming caused by increasing GHG emissions.” He reveals his lack of knowledge about the “greenhouse effect” when, @83, he accuses eclectic: “It is your narrative that grossly incomplete! You make a totally unsubstantiated assertion that without CO2 the oceans would freeze.” It is a correct assertion substantiated by a simple radiant energy balance over the globe: Solar In = Infrared Out.
The surface of the ocean and the land are blackbodies that absorb and emit radiant energy based on Planck’s Distribution Law. Gases, being simple molecules, emit at specific wavelengths as internal energy levels change determined by bending and stretching depending on the molecular structure. CO2 has many strong absorptance/emittance lines in the wavelength band of about 14 to 16 microns and many more weak lines on the shoulders of this band.
Absorptance equals emittance at thermal equilibrium (Kirchoff’s Law). That is the energy balance of a molecule. The condition of thermal equilibrium is important because it is conservation of energy, not conservation of photons at a specific frequency. Because the bottom layer of the stratosphere is cold, the intensity of emitted energy from CO2 is lower than the intensity emitted in the same wavelength band from the surface. Thus, energy emitted to space is reduced. With increasing CO2, the emittance lines fill in and the range of the CO2 emittance band becomes wider. Infrared out is reduced. Energy accumulates. The pre-industrial steady state balance when accumulation was zero is upset. Warming occurs until the energy balance is restored. It is restored when the temperature of the surface increases enough such that the energy emitted by the surface at other wavelengths outside of the CO2 absorptance band matches the reduced energy emitted to space from within the CO2 band.

Second, when you Bob told me to discuss this elsewheere I didnt know it was said by a moderator. You never made that clear, so it appeared you were just a random commenter deflecting the discussion.
I also believed the topic here was about the Climate the Movie and whether or not the facts presented in it were just refuted myths.
SkS topic 31 greenhouse stated the argument "Increasing CO2 has little to no effect" is a myth and that "The strong CO2 effect has been observed by many different measurements."
I had not argued about the greenhouse effect in general, just about how the ocean is warmed. Then Eclectic dishonestly alleged I denied the greenhouse effect. So please explain why his post is still up but my reply gets deleted?

Just Dean at 03:36 AM on 4 April 2024Renewable energy is too expensive
I came across a recent substack post by Energy Bad Boys, EBB, claiming that wind and solar make for expensive electricity. They used a very limited example of California and their home state of Minnesota to make that claim. I countered with Iowa and South Dakota that have very high percentages of wind and cheaper electricity, which they dismissed.
This motivated a more complete analysis using data from EIA, EIA electricity data browser , for 2022 for all 48 contiguous states comparing average retail electricity prices to the percentage of renewable electricity generation - wind plus all solar, i.e., utility solar plus small solar. The data for 2022 extends the percentage of renewables out to greater than 60%, Hosted images . (Sorry, I could not get the image insert function to work.)
The conclusion is still the same. There is no correlation between state electricity prices and percentage of renewables. If anything there is a slight trend towards lower prices with increased penetration.
Moderator Response:[BL] The ability to insert images is limited to images that are on a publicly-available server with a direct URL to the image. Your "hosted images" link goes to a Google page, not a stand-alone image. This site does not cache or store a copy of the image - it will only be visible as long as the original on the external site is still available.
It looks like Google does not allow such linking and display, even if you use the link that leads to the image only.

Bob
It is clear that you cannot look beyond one statistic about historical patterns.
It is not just one stat. Despite predictions. There has been no discernible increase in drought, floods, land burnt by bushfire, typhoons, hurricanes.famines, migration from hot to cold places. Actually people continue to move from colder to hotter places.Yes , there has been in heatwaves - but we have discussed the flipside of that before.
All the data is available on World in Data - it is interactive - just put in hurricanes or floods and it gives you the information

Hmmmm. You deleted my polar bear post because you deemed it off topic despite the fact I was responding to SkS' original post calling
"Polar bear numbers are increasing" is a myth and then stating
"Polar bears are in danger of extinction as well as many other species."
Clearly I was on topic and your subjectively deleting my post that refuets SkS' claim!
Moderator Response:[BL] Every single one of the entries in the table in the OP includes a link to the proper place where the topic can be discussed - and where the myths in the movie have been previously debunked.
I'll repeat the part from the Comments Policy, with added emphasis to the last part.:
- All comments must be on topic. Comments are on topic if they draw attention to possible errors of fact or interpretation in the main article, of if they discuss the immediate implications of the facts discussed in the main article.

Eclectic, LOL What are you talking about saying " Jim ~ you would lose all scientific credibility if you assert that the so-called greenhouse effect does not exist."
But truth is I have never denied the greenhouse effect. Your allegations are typical of alarmists trying to denigrate skeptics. Every skeptic I know totally understands the greenhouse effect and are grateful for its warming effect. The question is how much does further increased CO2 cause further warming and is that beneficial or not.
Your second funny is telling me not to get distracted by the details of the actual mechanisms of the ocean is warming, simply because you believe ,without ever substantiating, that there are equilibrium points that are unaffected by those proven dynamics.
Please educate yourself Eclectic.
Moderator Response:[BL] You're not getting the message. Re-post of off-topic deleted comment deleted again.
There are plenty of better threads here to discuss the Greenhouse effect. There is a box on the upper left of each page that says "Search". I'll let you try to figure out on your own what that is for.

William at 02:26 AM on 4 April 2024A data scientist’s case for ‘cautious optimism’ about climate change
I don't dismiss predictions and opinions.
I am however a great believer in evidence, especially hard evidence .
It is difficult to discuss matters with someone who ignores evidence because it does not fit their pre conceived opinion and biases.
If you say t will rain tomorrow -and I say it will not - and we both agree to a bet on it.
And it did not rain - you can't say I think it will rain nest week therefore i was right - and I am not paying you.
This is the basic tactic of climate alarmist - they keep being proved wrong - so they move the timelines. - the new timeline are wrong - so they move them again - and so on and so on.It is why people still say Thomas Malthus was right. One can never win with them - because they just say somethimng that is unfalsifiable .
It is like someone saying - prove there are no UFO
And btw – it is not just one metric deaths – there has been no increase in economic damage in real terms, no increase in droughts, floods, land burned by bushfires, famine , migration from hot places to cold. None of these ( despite 40 years of predictions ) have occurred – but yes you will be able to find new predictions – and maybe in your book – that means they have occurred.
Moderator Response:[BL] You have now crossed the line in terms of repetition.

But truth is I have never denied the greenhouse effect. Your allegations are typical of alarmists trying to denigrate skeptics. Every skeptic I know totally understands the greenhouse effect and are grateful for its warming effect. The question is how much does further increased CO2 cause further warming and is that beneficial or not.
Your second funny is telling me not to get distracted by the details of the actual mechanisms of the ocean is warming, simply because you believe ,without ever substantiating, that there are equilibrium points that are unaffected by those proven dynamics.
Please educate yourself Eclectic.

I would also take issue with SkepticalScience claiming Polar bears are in danger of extinction as well as many other species.
Polar bears are believed to be affected by reduced sea ice because their main prey, the ringed seal, remains in the Arctic all year and they give birth to their pups on the ice where they are very vulnerable to the bears.
• There are 2 types of sea ice. Land-fast ice and pack-ice. Unlike fast-ice, pack ice is mobile. When winds cause pack ice to collide with the shore or other ice slabs, the pack ice thickens as ice slabs are pushed on top of each other. Thick pack ice doesn’t melt completely in the summer. However, shifting winds can blow thick pack ice out of the Arctic, as happened in the 1990s9.
• Ringed seals depend on fast-ice. Thin fast-ice naturally melts completely by July, and then re-forms starting in October.To breathe, ringed seals must create breathing holes by head-butting through any newly forming thin ice. Then gnawing and clawing at the ice as it thickens, keeps their breathing holes open throughout the winter. Multi-year pack ice is too thick for seals to create breathing holes.
• Ringed seals mostly give birth to their pups on land fast-ice in March and April. Pups remain on the ice while nursing and then molting in June. Land-fast ice is thickest during the seals reproduction cycle and remains until late June. Seals then abandon the ice to hunt in open water starting in July and only crawl out on ice unpredictably to bask in the sun for a few hours. Melting ice after July has no effect on how available the seal pups are to bears.
• Polar bears gain almost all of their body fat in the late spring and early summer from feeding on baby ringed seals. In contrast, all bears lose weight during the winter when there is the greatest amount of ice. Feasting on baby seals from March thru June determines if the bears will survive the winter. Unlike feasting on baby seals, any feeding on ice or land after June is purely opportunistic. Pregnant females enter hibernation just as ice begins to reform and emerge only as ringed seals are giving birth
• Ringed Seal are so abundant they are considered a Species of Least Concern, so Arctic climate change does not appear to have had a negative effect.
• More open water from July to September increases sunlight reaching phytoplankton, generating greater photosynthesis and a more productive Arctic Ocean.3 Increased photosynthesis improves the whole Arctic food chain, eventually increasing fish populations that ringed seals depend upon. More ringed seals provide more food for polar bears.
• Since hunting polar bears was restricted, polar bear populations have increased.Moderator Response:[BL] Contents snipped - off topic.

Loblaw, You have said absolutely nothing to refute the science I preented here. Instead you try to eflect and redirect the issue. Not a very scientific approach. I will await your refutation here.
Moderator Response:[BL] No, I was trying to give you a polite nudge to post things in places where there are on topic.
Skeptical Science has a Comments Policy. There is a link to it above the edit box you use to type in comments. You agreed to follow that policy when you signed up for an account. The first two sections of it are:

Bob Loblaw at 00:39 AM on 4 April 2024A data scientist’s case for ‘cautious optimism’ about climate change
William:
It is clear that you cannot look beyond one statistic about historical patterns.
I value the opinion of the authors of a study much more than I value your opinion about it.
Your dismissal of any predictions whatsoever (except, it would seem, your own opinions) shows a state of denial of anything scientific. It makes me wonder how you can get out of bed in the morning, since it is impossible for you to predict whether or not the floor will support you.

nigelj
At what point - would you start to not trust a climate alarmist - if deaths continue to fall or not rise for another 40 years - would you think maybe we should not trust those who make these predictions and fuel the narrative. Or do they just get a forever pass - and you will always accept more predictions - even though the people and movements who made them before have always been wrong.
I think people just want to believe things will be terrible and there are primed believe end of days narratives.
Yes - anything could happen in the future and deaths and damage levels could rise again- but it is nor healthy to ignore the present - or trust people that wilfully distort it.

BOB
This study shows the negative health impacts of climate change that, under high-emission scenarios, would disproportionately affect warmer and poorer regions of the world. Comparison with lower emission scenarios emphasises the importance of mitigation policies for limiting global warming and reducing the associated health risks.
Rather typical you have when presented with a fact, come back with someone's opinion and a prediction.
You can't disprove a fact with a new prediction. As I said before - we could have this conversation in 40-years’ time, and you or other alarmists would still answer a fact with a prediction.Nothing that occurred matters. Evidence is always dismissed with evidence of a prediction.

Gentlemen:
The proper place to be carrying on this discussion about ocean heating is on this thread:
https://skepticalscience.com/How-Increasing-Carbon-Dioxide-Heats-The-Ocean.html
Yes, the original post in that link is from 2011, but it is still open for comments.
Scaddenp is correct in pointing out (in comment 70 here) that jimsteele is regurgitating debunked myths from more than a decade ago. Jimsteele: please actually read the appropriate post and comments before you start repeating yourself.

John ONeill at 21:30 PM on 3 April 2024Is Nuclear Energy the Answer?
The grids with the lowest emissions worldwide are not those with the deregulated power markets that came in first under Pinochet in Chile, then in the UK under Thatcher, and subsequently mostly from about 1995 -2004 in parts of the US, Europe and in Australia (1998 under Max Bradford in New Zealand.) Those have not demonstrated the capability to grow capacity, and slash emissions, that will be needed if we want a real transition. For most of the last forty years, in first world countries, demand was static, and the market system only acted to replace existing capacity, not cover expanding uses. (Nor did it give the lowered prices promised when the reforms were introduced.) The lowest emissions are mostly in areas with large, government-run entities, using either hydro - Hydro Quebec and BC Hydro in Canada, Electrobras in Brazil, Statkraft in Norway - or hydro and nuclear - Electricite de France, Ontario Power Generation, Vattenfall in Sweden. Governments can supply the 'patient money', from superannuation funds, needed for long-term energy projects. Private companies, with management usually only staying in the job a few years, pay more attention to quarterly earnings than is needed for projects that will span many generations. A reactor takes years, and a lot of work, to bring online, but once done nothing compares for abundant clean power.

Jimsteele @83 :
Certainly the ocean skin surface is the gateway through which heat enters & leaves the ocean. (Other than the large flux of solar radiation which penetrates deeply into the ocean ~ we scuba divers can definitely see that occurring ! )
But as I mentioned above, the skin surface dynamics do not disturb the long-term equilibrium of energies, over the course of days and years. Surely that is obvious to you. Please do not confuse & distract yourself with the ephemeral fluctuations in the surface few microns of oceanic water.
Also ~ do not distract yourself with thinking about the different heat fluxes in the tropic / temperate / and polar zones of the planet. Those zones have their own long-term equilibrium positions, and their existence (and fluctuations) won't change the medium-term equilibrium of the total planet.
Second ~ please educate yourself about the paleo history of Earth . . . and its "iceball" phases. Yes, the paleo evidence indicates low armospheric CO2 produces "iceball" oceanic freezing. In addition to that evidence, the basic physics of Earth's planetary orbital distance and the incident solar radiation on Earth . . . indicate that the Earth's oceans would become meters-deep in ice, if the atmospheric "greenhouse" effect were to disappear.
Jim ~ you would lose all scientific credibility if you assert that the so-called greenhouse effect does not exist. Please step back from the brink . . . and reconsider your position.
-
jimsteele at 13:43 PM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Eclectic, First the skin surface dynamics are essential. The skin surface is the only layer from which heat can leave the ocean.
Second It is your narrative that grossly incomplete! You make a totally unsubstantiated assertion that without CO2 the oceans would freeze. You totally ignore solar heating. However the heat flux into the ocean primarily happens due to tropical solar heating in the eastern oceans, where La Nina like conditions reduce cloud cover and increase solar heating. The ocean sub surface can trap heat but the skin surface cannot.

Eclectic at 12:57 PM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Jimsteele @81 :
Thank you ~ but the analysis is still incomplete. Possibly some semantic obfuscation or confusion is impeding the basic physical picture.
Over a 24 hour cycle or 365 day cycle, the interesting variations in the topmost few microns of ocean are unimportant. What is important is the overall flux of energy into & out of the ocean ~ for that is what maintains the ocean's temperature structure (stratification) and long-term heat content. And the ocean is responsible for a large slice of the atmosphere's heat content & stratification (indirectly). It goes both ways.
Remove CO2 and the lesser greenhouse gasses . . . and the ocean temperature would decrease . . . and the surface few microns would be ice (and the deeper ocean would freeze as well).
Ergo ~ and in straightforward language ~ it can be accurately said that CO2 has a major effect in warming the planetary ocean.
-
jimsteele at 12:26 PM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Eclectic to be more complete
First understand, CO2 infrared only penetrates a few microns depth compared to solar heating that warms the sub-surface for several meters depth, creating the diurnal warm layer
Second, the ocean’s skin layer is the only layer where heat can ventilate from the ocean. Absorbed solar heat creates a temperature gradient where conduction moves heat from the diurnal warm layer up towards the skin surface and out to the atmosphere. 98% of the time the ocean heats the atmosphere. The atmosphere does not heat the ocean.
The skin surface is always the coolest layer because as soon as any downward infrared from greenhouse gases heats the skin surface, the skin surface radiates that heat away as the laws of physics dictate! Furthermore, any heating of the skin surface increases evaporation and promotes evaporative cooling. And finally the skin surface heat is conducted away by the atmosphere. Thus even at night after most solar heat has been ventilaated, the skin surface is cooler than subsurface layers.
Measurements show the skin surface radiates away infrared from the combined inputs of solar heating that rises to the skin surface and infrared heating absorbed in the skin surface. The skin surface cannot trap heat. However subsurface layers trap heat because of the time delay of that heat reaching the skin surface to ventilate. Furthermore, heat is trapped in the ocean where ever solar heated subsurface layers are overlain by fresher water that suppresses convection.

Jimsteele @76 :
You have answered incompletely. Have I missed something basic in physics or in logic ? e.g. ~
Solar shortwave radiation -> ocean
ocean heat -> atmosphere by molecular vibration and by IR radiation
atmospheric heat -> ocean (predominantly by molecular vibration, but a small component of IR radiation too)
CO2 -> greenhouse effect -> lower atmosphere warming [lapse rate]
Ergo, CO2 provides a large (but indirect) amount of ocean warming.

jimsteele at 12:05 PM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Hi John,
Warming the surface stratifies the oceans' upper layers. Turbulent mixing mostly increases the cooling effect by bringing warmer subsurface water to the skin surface. The ocean's mixed layer deepens in the winter as the upper layer cools.

John Mason at 11:30 AM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Jim, what about turbulent mixing?

jimsteele at 11:20 AM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Hi Eclectic, No you are wrong to claim "In summary ; the ocean receives heat predominantly from light energy and from conduction from the atmosphere."
Conduction is negigible if at all.
The diurnal warm layer created by greater subsurface heating from the sun creates heat conduction out of the ocean and towards the skinlayer which is the only layer from which heat can leave the ocean.
Once infrared heats the ocean's couple of micron thick skin surface, the warmer surface begins emitting infrared and cools the skin surface. Basic physics! Heating the skin surface also increases evaporative cooling and 98% of the time the atmosphere is warmed by contact with the ocean's skin surface. Basic physics does not indicate CO2 infrared can heat the ocean.
-
jimsteele at 11:15 AM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
scaddenp SCIENCE OF DOOM had many accurate posts but regards heating the ocean he/she failed miserably. So I ould appreciate hearing your understanding, instead of pawning the issue off to someone else.
He first presented the idea of conduction as important for OC2 heating with "Once you establish a temperature difference you inevitably get heat transfer by conduction"
Indeed, the diurnal warm layer created by greater subsurfac heating by the sun created heat conduction towards the skinlayer which is the only layer from which heat can leave the ocean.
Once infrared heats the ocean's coup;le of micron skin surface, the warmer surface begins emitting infrared and cools the skin surface. Basic physics! Heating the skin surface also increases evaporative cooling and 98% of the time the atmosphere is warmed by contact with the ocean's skin surface. Basic physics does not indicate CO2 infrared can heat the ocean.

Eclectic at 11:02 AM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Jimsteele : help me understand your position.
m
At the most basic level :- solar radiation at visible wavelengths does penetrate 10's of meters into the ocean. (As a scuba diver, I can vouch for this.)
At other wavelengths, into the infrared & longer, there is shallow or deep penetration, but the actual penetration flux is tiny in comparison to the visible light. (That includes the infrared flux radiated from CO2 in the lowermost few meters of atmosphere.)
Then we have a large flux of energy (both out of and into the ocean) from molecular vibrations at the ocean/air interface ~ vibrations of molecules of water / water vapor / nitrogen / and oxygen. I have not chased down the magnitude of such flux into and out of the ocean ~ but presumably that magnitude is huge.
In summary ; the ocean receives heat predominantly from light energy and from conduction from the atmosphere. CO2 molecules have only a very tiny direct ocean-warming effect ~ but arguably a huge indirect warming effect through CO2's action as a greenhouse gas warming the planet's atmosphere.
Have I understood that correctly ?

scaddenp at 10:04 AM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
Jim, the myth that backradiation cant warm the ocean. I freely admit the author of Science of Doom knows more about this than I do, so I suggest you take it up with him if find the argument unconvincing.
-
jimsteele at 08:01 AM on 3 April 2024Climate - the Movie: a hot mess of (c)old myths!
LOL you say "I havent heard that myth for a decade or so" Exactly what myth are you insinuating???
You seem unable to distinguish solar irradiance vs solar insolation!?Clouds provide a huge determination of solar insolation but not irradiance . Please explain your viewpoint. Otherwise it appears you dont know what you are talking about!
