Even if you haven't been worried (yet) by current increases in extreme weather events, this should ring alarm bells. These currents are what keep the UK and other northern European countries relatively warm compared to Greenland. : BBC News - Antarctic ocean currents heading for collapse- report

@Raggletagglegypsy Lindzen doesn't claim that either the science or the models "are intrinsically wrong" . He acknowledges anthropogenic climate change. You are completely taking his narrative out of context.

I actually totally get what he is talking about, Navier-Stokes, Newton, Euler, CFD. His approach is very very purist, to the point of naivety.

You have 97 scientists saying don't jump and three saying just jump and let's see what happens. What do you do?

Agreed @Daftasabroom Having looked into it further, you have to be careful to fact check things @Raggletagglegypsy. I saw your video link to Lindzen, which led me to look at his other stuff and post his conversation with an economist. There are certainly aspects of his questioning of the science and politics that seem plausible. But I am not a scientist and there do seem to be plenty of reputable scientists at places like MIT who take issue with Lindzen's position. This is a useful rebuttal of his likening to belief in climate change as a belief in magic - https://climatefeedback.org/claimreview/scientific-evidence-indicates-modern-warming-driven-by-co2-contrary-to-richard-lindzen/
We are in unchartered territory, and that is alarming.

Scientific evidence indicates that modern warming is driven by CO2, contrary to Richard Lindzen’s claim

Climate change is not only evidenced by increased global average temperature, but also by increased ocean-heat content, Arctic sea ice decline and sea level rise. All of the scientific evidence, including observational datasets and climate models, indi...

I know this thread is done now, but I just wanted to pop on to put another argument forward for human-caused (anthropogenic) climate change.

Some businesses, like Shell, BP and ExxonMobil are very rich because they sell fossil fuels. Some countries are very rich because they have fossil fuel resources, like Saudi Arabia and Russia. These businesses and countries have the most to lose from us transitioning away from fossil fuels. And right now they have ludicrous amounts of money.

Suppose for the sake of argument, that anthropogenic climate change wasn't real. The businesses and countries that are rich from fossil fuels, could pay for the scientific research to prove that it was all false alarm, and hence secure their business model, meaning they can continue to be rich in the future. They wouldn't need to worry about university funding biases, they have billions and billions of dollars, they can setup their own institutions and pay people to do all the rigorous evidence collection, analysis and modelling that'll prove their point, and then present that data and analysis over and over again to the other scientists, until they understand and agree.

But they haven't. In fact, if you went on the website of a fossil fuel company, there'd be various sustainability and net zero type targets and pledges. They probably don't really give a shit about the consequences of anthropogenic climate change, but even these companies, are publicly and vocally supporting the idea.

You could argue they've been forced into this position somehow by other powerful forces. But really - in all companies, and all countries - even Saudi Arabia, Russia and China. They've all had the time, motive and resources to disprove anthropogenic climate change, if that were possible. So you have to conclude, it's not possible to disprove anthropogenic climate change, because it's actually a true thing.

@BocolateChiscuits
I don't think it is settled. I think there are very powerful arguments why the global warming narrative acquired traction, which were political rather than scientific.
Economic decision-making occurs within socio-political frameworks. The sort of big businesses that you mention, despite their size, do not have sufficient power to survive without being impacted by external drivers. They can only remain profitable in the long term by satisfying investors and consumers - and importantly also have to operate within the parameters of legal constraints at both the national and international level, to meet the demands of the net zero agenda. Hence they adopted a strategy of greenwash and started restructuring in order to survive in what has been a rapidly emerging, new political environment. The very act of satisfying external scrutiny to appear 'environmentally friendly' has brought about powerful changes. I don't think it would be reasonable to think that it would now be feasible for any business to survive, whilst trying to promote support for a scientific interpretation that does not accord with the current socio-political narrative. That is how paradigms work.
Prof. Lindzen, who has been referenced a couple of times in this thread, is an eminent atmospheric physicist who has clearly tried to comprehend how this powerful narrative unfolded.
Below are a few more of his very recent interviews that might help give an alternative perspective. He gives good reasons why the so-called consensus amongst scientists is pretty meaningless and, whilst agreeing that warming since the 1950s may be anthropogenic, takes the view that it is at such a "tiny" level as to also be pretty meaningless!
As Lindzen explains, the simplistic way science has been used to give the public
the impression that it has been understood cannot really be countered by the
complexities of atmospheric physics. Simple narratives will always be the ones
that can be most readily manipulated through propaganda. Lindzen
does not envisage a doubling of CO2 producing more than half a degree temp.
increase. However, it is also a fact that CO2 is pushed as the cause of every possible climate outcome - so, in reality, no possible counter-evidence could be validated through predicting alternative climatic outcomes. This current climate change juggernaut cannot really be stopped, irrespective of science - hence, it probably is a debate that is, as you say, "done now"!

Don't worry, only the first minute is in French!

@BocolateChiscuits Actually, this is a very comprehensive interview that contains a good balance of the political context, along with the basic scientific problems associated with the overarching theory. I know Jordan Peterson is rather a controversial figure, but he does a good job here playing devil's advocate and challenging Lindzen.

@Raggletagglegypsy you still haven't shown a single shred of scientific evidence to support your beliefs. A Lindzen podcast is not evidence.

You are implying some kind of massive conspiracy theory.

BocolateChiscuits · 06/04/2023 11:36

@Raggletagglegypsy I don't see how socio-political frameworks could've worked so universally, against such money and resource rich companies and countries, with multiple different economic and political systems. In Saudi Arabia they're publicly beheading people, but somehow socio-political pressure stopped them bunging a billion or two into securing their country's entire income by simply collecting the evidence and definitively showing anthropogenic climate change isn't real.

I watched the videos from your first post, and also found one where Lindzen is presenting at the 20018 Annual GWPF Lecture. I hadn't seen your second post, so I'll try that too, when I get a chance.

As far as I can tell he his main points are:

  • He thinks that Earth is less sensitive to CO2 increases, than normally thought. He thinks if you double atmospheric CO2, you would get a 0.5 degree increase. He thinks warming above that is because of coming out of a mini-ice age and long-term climate trends and oscillations.

(Currently, we're at a 50% increase in CO2, with a 1.1 degrees total warming, although a chunk of that is thought to be from methane (about 30%) and some from other GHGs.)

  • He thinks the complexity of the ocean, land and atmosphere, and all the various cycles and energy movements and transfers going on makes it impossible for us to make predictions. He thinks climate models are not nearly complex enough, for instance, they don't model local and daily temperature changes. Although, for some reason, he, himself, is able to make predictions.

I think the level of detail he's asking for isn't realistic, and misses the point of a model - it sounds like a really, really long-range weather prediction, and we can't do quite short range weather predictions, (who knows, maybe something like AI or quantum computing will make it possible one day).

  • He thinks the Earth's systems will naturally act to stabilise temperature changes from CO2. But I wasn't clear on how. Also I wasn't clear on why they would stabilise CO2 temperature changes, but not the ones he says we're experiencing because of coming out of a mini-ice age.

  • He thinks we've been all been hoodwinked into believing anthropogenic climate change because it's been communicated as such a simple message, and general level of scientific understanding is so low. In the GWPF lecture he explains a lot of science - it sounded impressive, but actually I learnt a lot of what he said already in an Earth Science topic in the first year of a part-time science degree I've been doing, and as part of my physics A-level years ago. He didn't have some massive scientific insight that nobody else had, and he didn't do a great job of explaining the relevance of all the bits of information to his central claim.

  • In the GWPF lecture he talks more about the motivations behind the hoodwinking. It's very culture-wars. The left-wing is now rich and powerful, and want to force a societal/technical/economic revolution that will benefit them, and force all the poor, right-wing people into a backwards, medieval life. The evil rich, left are doing this by scaring the population into the climate change narrative. The scientists are going along with it because of funding.

God, I hate culture wars. Simplistic science you say Lindzen - what about your simplistic understanding of politics, people, economics and technology. People are acting on climate change for all sorts of reasons, but I should imagine machiavellian reasons are very rare. Mostly it's because people are worried and give a shit about other people. And it's not about making us poorer, or giving us a medieval life style - renewable energy, insulation, heat pumps, electric vehicles, will end up making us richer, because we won't be giving fuck tonnes of money to embarrassingly rich companies and then simply burning what we buy, and leaving us in a position where we just have to buy more and burn it tomorrow. Not to mention, if we stop all the pollution associated with the burning, we'll get healthier. Also, how do Saudi Arabia and BP etc. fit into the left-rich-oppressors vs. right-poor-oppressed narrative?!

  • Lindzen says CO2 is a plant fertiliser. They pump CO2 into green houses to increase crop yields on things like tomatoes - it works in these conditions because in a greenhouse they're also controlling the moisture/light/temperature/nutrients to optimal levels. Outside of the greenhouse, plants are in ecosystems, and they don't have controlled levels. If you think of something like the drought and heat we had last Summer in the UK, that harmed plants way more than they were helped by having higher CO2 levels. It'd be like me smashing a big hole in your bedroom wall, so you have to sleep exposed to the elements every night, and then giving you a plate of broccoli every day and saying, it's fine, you'll be healthier.

@BocolateChiscuits and @Daftasabroom Thank you for your responses. I actually really appreciate the thought that you are giving this, because I am conflicted. I am sorry to have posted so many videos, I guess once I have watched something and found it interesting, I genuinely want to know what other people think - and I am grateful to that you have taken the time to give your opinion.
I have a busy weekend, but when I have a chance, I will definitely have a look at your links and have a think. In the meantime, I have ordered a book called "Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters" by Dr Steven Koonin (physicist, astrophysicist and served as Undersecretary for Science in US Energy Dep. under Obama).
I would say that I don't think it is a simple matter of being able to produce a single piece of evidence to counter the narrative - as the disagreements seem to rest at the level of magnitudes of interactions, feedback loops (the degree to which these are likely to be constrained by le Chatelier's principle etc) and whether this is being modelled correctly in the extra-tropical regions. One argument that did seem particularly compelling (and had occurred to me independently, before hearing this) relates to the fact that if amplification of warming is occurring at the poles, this would reduce the temperature differential with the equator - in turn, this should be linked to a reduction in meteorological extremes.
Anyway, I have taken up enough of your time - and, as I said, I have appreciated your thoughts and will certainly mull them over. Have a good Easter! 🙂

Raggletagglegypsy · 06/04/2023 20:08

Also, @BocolateChiscuits , I completely agree with your sentiments about the need to restructure economies to become more sustainable (and topple the current dependency on huge multinational corporations). Also, regardless of the global warming debate, achieving energy security (along with food security) at a national level should be high on our agendas...particularly given the fact that, ultimately, fossil fuels are obviously finite. In that respect, the global warming debate is sort of academic!

BocolateChiscuits · 07/04/2023 23:48

@Raggletagglegypsy have a good Easter too!

That book sounds interesting. Let us know how you find it.

Raggletagglegypsy · 08/04/2023 09:54

@BocolateChiscuits I will - just have to try to make the time to read it! 😋

Much of what is being debated here goes over my head I'm afraid, but I do remember David Attenborough stating tnere is no doubt that human activity is the cause of climate change. (Not his words exactly but certainly along those lines)

Then on the other hand, you have Neil Oliver claiming reports were thrown away which didn't fit the argument that climate change is caused by human activity and the evidence was manipulated somehow. Sorry can't post link as I can't find it!
