Steven Koonin on The Limitations of Climate Change Models

[@richardanthony462]

Thank you Dr. Koonin. As an electricity supply engineer with a strong interest in physics and environmental impacts of energy production, I have been trying to explain these same climate and weather fallacies, especially the absence of a "crisis" and the immorality of premature "net zero" policies, to friends and professional associates for years. My career limiting reward was to be told that I am "on the wrong side of history" and a "denier" of "the science" by people who (ironically) refused to discuss climate issues at any scientific level, preferring to lazily argue from (political) authority. Given your impressive credentials I am hopeful that many policy makers will listen to your sound advice and realize the laputan foolishness of the rush to net zero policies being imposed in North America and Europe.

[@bthyner]

Thank you so much for the open discussion you can't even talk about with most people and answering questions i have had for a long time.

Many lie about climate-change, as Hbomberguy has proven beyond doubt

[@manfredsalm5208]

Steven Koonin is not a climate scientist.

[@abuyusef27]

I’ve listened to SK and read his publications now and can see he has a real thorough grip on the subject. Here he pulls out a number of key points from his extensive knowledge that really nail it for the man in the street. Why o why can’t our politicians and policy makers just listen to an expert for once rather than teenage activists?!

[@anthonymorris5084]

Well said.

[@roblouw1344]

When are enough people going to start listening to genuine experts like Steve Koonin? Everybody should read his book 'Unsettled".

[@nathanngumi8467]

A great lecture! I enjoyed his book Unsettled. The world needs to proceed very carefully on how the negative effects of climate change are dealt with. Mistakes and politically-induced missteps can be fatal.

[@CS-gg5hx]

The path to so-called ‘net zero’ has already been set. With trillions already spent and many more trillions committed, there is no way politicians and governments will allow any deviation from current policy. It would be an admission that they were wrong and that can’t be allowed, at any cost.

Re cooking with dung, etc., here in Ecuador natural gas is subsidized to encourage its use instead of dung, wood, ag waste, and charcoal.

[@007kingifrit]

every generation thinks they are in the end of days. this one doesn't strike me as much

[@michaelhiggins2562]

Thank you Dr. Koonin! What ever happened to the Academies commitment to truth?

[@slevinchannel7589]

Many lie about climate-change, as Hbomberguy has proven beyond doubt

[@andrewlm5677]

I think a great point is made here on the value of transparency. The idea that the public can’t handle ambiguity and that a “noble lie” to simplify the presentation of the climate problem is justified is just sowing distrust as people see through the lie. You’ve then lost the ability to have people listen to you when you are more truthful. The earth and it’s climate are a complex machine - we need to understand it and those dedicating their careers to that pursuit do humanity a great service. There is nothing wrong with acknowledging that we have more to learn or to suggest that, even though we don’t know everything, there are actions that we should consider taking based on our current, imperfect, understanding

[@anthonymorris5084]

Agreed. It should be noted that there are two entities in this discussion. There is the scientific community and there is the "climate movement". They are not synonymous and nor is their message. The climate movement is activists driven with a political agenda. They feed off of media hyperbole and its continued misrepresentation of the science. The climate movement is authoritarian. Warming is science. The climate "crisis" is purely political. Cheers.

[@gastaotaveira]

A great summary of the current state of climate science. A must see.

[@anabolicamaranth7140]

Ignore the models. The most fundamental, informative climate metric is earth energy imbalance. More solar energy coming in than is being radiated out and you have a warming planet. EEI was around .5 Watts/sq meter in 2000 and has steadily risen to 1.92 W in June 2023. About .2 of this is from increased solar output. Bottom line is 1.92 guarantees a lot of warming ahead, it is a simple matter of physics. A pot of water on a burner with more energy coming in than what is being radiated out will increase in temp. No model needed.

[@anthonymorris5084]

Life flourishes under warming.

[@saltburner2]

Sadly, too many prefer Grete's adolescent hysteria to Steve's detailed science.

[@thomasfsan]

Because nothing's fucking happening, and we're gambling with our only home. Meanwhile summers here where I live have become unbearable, and the thought of it getting worse makes me want to move somewhere colder. Meanwhile, we can replace fossil for most of our energy use. It's called Nuclear.

[@antizwets5904]

I prefer an actual complete description of the climate crisis instead of this selective cherry picking of Koonin to sell books.

[@slevinchannel7589]

Cool but all scientists say climate-change is real so arent you hysteria-driven yourself, bro? I mean, you DO have your specific Beliefs literallycovered by flat-earth-debunk-channel

[@tobyw9573]

What is the upper efficiency limit of photovoltaic power? Virtually everyone has a roof. And Kudos to Dr Steve Koonin for his thoughtful presentation!

[@climateroulette3178]

At least this channel doesn’t shadow ban dissenters, give ‘em some cred for that.

[@TheRealStevoBrown]

It was really really really cool to be able to hear someone coughing through the entire talk. I like that a lot and I wish more talks had it.

[@lawrenceralph7481]

Uncalibrated, unverified models of complex systems have greater uncertainty than those that can be verified by comparing predictions to outcomes.

[@tomwinstanley1915]

Adding to what others have said, "Unsettled" is a brilliant book and well worth the time and money.

[@CSGATI]

They can be programed to prove or disprove your point. They also leave out so many variables they are not accurate.

[@peterclark6290]

Factor in the expanding effect of Regenerative Agriculture (RA) to the graph @ 20:50 (with the increased nutrition in every RA meal) this world is in a good place. Then factor Hans Rosling's observations of what wealth does to limiting population expansion it gets even better. Our biggest threat is the expansion of desertification on arable land which RA has an effective, relatively cheap and simple response (Allan Savory and Dr. Walter Jehne, et al). A beneficial confluence.

[@wheel-man5319]

But desertification is not happening.....

[@MrCarlGW]

I disagree with the population of Asia growing so long. China is losing population now and India birth rates just tipped below replacement level. India should begin losing population in 25 years. Only Africa stands to gain population this century. My figures show global population should plateau and begin declining by mid-century.

[@wheel-man5319]

That's my take as well.

[@anthonymorris5084]

Over population is at the foundation of almost every single threat facing humanity and nature. The climate movement doesn't care.

[@anabolicamaranth7140]

“Heat records are due to urban heating.” Indianapolis, Columbus, Pittsburgh have set zero heat records in the month of July in the last 10 summers. Atlanta hit one lousy record, 101F on 7/25/16. Atlanta is a heat island. Seattle has 6 July records highs in the last 10 years. Dallas 4, El Paso and Phoenix 17 each. Why the huge difference? Most of the coal plants are in the East and sulfates keep a lid on summer temperatures. Spain and France have demolished records the last 5 summers. Why? Very LOW sulfates. India, in the month of May has barely warmed at all since 1951. Why? Very HIGH sulfate levels. Better keep burning coal, the dirtier the better!

[@masada1520]

Thanks for a very enlightening lecture.

I live in Italy, net zero is NOT WORKING !!!

[@anabolicamaranth7140]

9:21 - Steven, we don’t live in the lower atmosphere, we live on the SURFACE. Surface temps have gone to the moon in the last few months, obliterating the last El Niño which was stronger than the current one.

[@Dan-uf2vh]

Several decades ago, there was a lead denier for the gasoline industries ... history repeats itself, even when the situation and understanding are clear.

[@TGenoRock]

Sad that you don't (can't?) Actually make a substantive point on the actual video.. or any of the evidence presented by Koonin. We will wait for the substance.

[@graziflorida4377]

Is Prof Guy Mc Phersons , prof emerit in Biology ....reliable?

[@RubenCLeon]

Does aluminum float? 27 = molecular weight of aluminum 44 = molecular weight of CO2 18 = molecular weight of H2O 15 = molecular weight of air Why not mention the "fact" that CO2 is 50% heavier than aluminum? Why not mention the "fact" that CO2 is more than 100% heavier than H2O? Why not mention the "fact" that CO2 cannot physically accumulate in the atmosphere? Why not mention the "fact" that the "green transition" is based on a physical impossibility? Less CO2 is a crime against humanity. More CO2 means more plants, more crustaceans, more corals, more diatoms and more food for humanity at a lower cost which means less world hunger. Less CO2 means less of all life at a higher cost and is a crime against humanity.

[@thomashead7528]

I had great teachers back in the 70s... They taught us what is happening now... Anyone denying is lying to themselves

[@ahriman1608]

🤕

[@anthonymorris5084]

I was in school in the 70's and nobody taught us that the planet was warming and that we were all in peril. In fact, the media was hyping an impending ice age, and every ice age narrative began with "scientists say" in order to validate this nonsense. Later came the threats of global starvation by the 1990's and I also lived through the 1973 energy crisis when we were told we were running out of oil. Warming is science. The climate "crisis" is purely political.

[@huntera123]

Thank you.

[@graziflorida4377]

we reached 1.6 degrees today......

[@DarkHorseSki]

The models are limited, but when we look back at the models, even going back to the 80's, there are dozens that have matched very well over the past several decades.

[@garysarela4431]

Scientific American debunked Steven's book. Source: Scientific American, May 2021, "A New Book Manages to Get Climate Science Badly Wrong"

[@johnanderson1421]

He's been repeatedly exposed as a distorter of climate data - cherry picking data, arguing with outdated models - with deep ties to the oil industry - five years as BPs chief scientist. One of Koonins own graduate students, Mark Boslough, has written an extensive critique of Koonins work as has Scientific American.

[@mikedavis8660]

Mark Boslough’s “extensive critique”, which I just googled and reviewed, is neither extensive nor critical in any meaningful way. It comes across as a classic hit piece attempting to discredit Koonins book without providing any substantive evidence of anything. Particularly ad hominem is the accusation levied that Koonin is a climate “denier”. Apart from the fact that the term “denier” is preposterously simplistic in the context of the highly complex subject at hand, it is patently untrue in Koonins case because he basically agrees with the concept of human induced climate change and furthermore agrees with what the IPCC reports actually say.

[@musicarroll]

And even Bill Nye the science guy disagrees with Koonin. So there!

[@lukehoefler4317]

amazing work of denial

[@cumulusterraticus3446]

May be ? All in vain-- dear humans-- without enough money for special technological aid !

[@tonykelpie]

Debate about models isn’t really necessary when these days one only has to look at the news.

[@scottekoontz]

Sadly, too many prefer Steve's adolescent shilling to the super majority of actual climate scientists' work.

[@TheJeffcurran]

Regarding "the super majority of actual climate scientists' work". Start by following the money. The source of grants and donations that created this super majority. These people need to pay the bills like anyone else. If they have to bend the science to continue getting a pay check, they will. Are you suggesting that scientists are too pure to tell a lie just because they are scientists? Also take note that an entire new energy sector is taking shape in parallel to the existing sectors. Not replacing them. The investment and economic opportunities are enormous to the few that can get on the boat. Check, if you can, the investment portfolios of the political and corporate elite that are promoting alternative energy policies.

[@tobyw9573]

The effect of electric bicycles and small vehicles should be significant.

[@wheel-man5319]

In making sure China keeps having slaves.

[@anthonymorris5084]

The Canadian government is writing cheques to rich people so they can trade their BMWs in for a Tesla. Meanwhile the millions of people taking the subway every day in Toronto get squat. The people who purchase Tesla's get a green license plate so they can drive around virtue signaling, pretending that a luxury automobile is good for the environment. This is the climate movement at work.

[@TGenoRock]

Not sure what your point is? Please elaborate on eBicycles and small vehicles actually change anything.. might actually increase electricity/energy use in net?
