Interesting information being imparted here around CO2 and it certainly is worth reviewing further.
At the risk of both of us being banned by the mods, I can only say that you are totally and utterly wrong. GHGs, primarily CO2 in the current epoch, are the major determinants of how warm it can get. You have no basis for your assertion.But coal was created prior to the bacteria that can eat the trees and make methane. There’s no new coal being made so that process can’t work as a cure here.
I’m not misunderstanding at all. If you think governments don’t have agendas then you’re incredibly naive. Governments fund research often because it creates business opportunities that their friends then get grants to fulfil. If you open your eyes and look at the whole system there’s a very clear bias and money trail. Right now CO2 is the focus and it’s being milked for all it’s worth and until that money dries up no funding will be used to disprove CO2 as the problem. To anyone with half a brain CO2 is obviously not the problem, yet here we are spending money on tree planting and seagrass. There’s still no tax on jet fuel though, so it’s clear that solving the problem isn’t the goal.
As ever, you've entirely misread my post, I didn't say greenhouse gases weren't an issue. You seem to be itching for an argument here and I can't work out why. The rest of us find the topic interesting enough to read and discuss the full picture, if you took the time to listen and digest you may find you learn some new things too.At the risk of both of us being banned by the mods, I can only say that you are totally and utterly wrong.

OK. I do not understand your train of thought. I agree it is an interesting topic. I would like to see an explanation of why CO2 is not the problem . In other words why have global average temperatures risen by about 1.5 degC since 1900. Why are sea levels rising at an increasing rate?As ever, you've entirely misread my post, I didn't say greenhouse gases weren't an issue.

Certainly not Lucy....ITV pay a girl with big bosoms.
The concept of GHGs heating the atmosphere dares back to the 19th century. But, it was not until the late 1950s that we began measuring the incoming and outgoing radiation (from high flying aircraft) and not until the late 1970s that we began to get global measurements continuously from satellites showing how much heat was absorbed by the various gases. The first IPCC report was in 1990. That provided a broad overview of climate change science, highlighting the scientific evidence for warming and the role of human activity in increasing greenhouse gas concentrations in the atmosphere. Subsequent reports have not changed the broad conclusions. They have looked in more detail at the problem.The problem is that the right answer changes with time and research. People who were right 20 years ago may have outdated views. That’s why discussion is useful. It certainly helped when we were discussing AI weather forecasting where some experts eventually did a u-turn and read some current research.
It’s not a train of thought, it’s current research! CO2 isn’t the only problem. We could remove all CO2 from the atmosphere but if that raises methane levels not only would warming continue but it might be harder to deal with and potentially accelerate. You have to look at the whole system and right now that’s not happening because people are overly focused on a single gas and all funding is aligned to that gas. As a result of this we’re seeing things like tree planting and seagrass schemes which have both been shown to have a net negative effect. This effect is ignored because of the sheer number of people who agree that carbon capture is the answer and the relatively low readership of any evidence to the contrary.OK.

Perhaps if you broaden your reading from climate and weather you’ll find answers. The effect of gases on climate seems to be understood and I’ve not suggested any of that has changed. The methods to change levels are absolutely not but this is not climate research it’s biology, chemistry etc.That provided a broad overview of climate change science, highlighting the scientific evidence for warming and the role of human activity in increasing greenhouse gas concentrations in the atmosphere.

You overlook the interdependence between CO2 and CH4. I have not looked for one, but if you did a multiple regression exercise, you would find that virtually all the variance of global mean temperature was accounted for by CO2. That is not because methane is not important, it is because the two are so heavily interlinked. Remember also,that CO2 has a much longer life in the atmosphere. Methane has a much shorter life. It is a more powerful gas molecule for molecule but in far smaller amounts. Methane and other gases have to be accounted for but CO2 is still the primary concern.It’s not a train of thought, it’s current research! CO2 isn’t the only problem.

I well remember being with John Houghton in 1990 when he really grasped the fact that it was not just atmospheric physics and dynamics that had to be understood. It was the total system, atmosphere, oceans, cryosphere, biology and man’s effects. If you look at IPCC reports you will find sections on them all.Perhaps if you broaden your reading from climate and weather you’ll find answers.

what happens to carbon after a tree absorbs it is the question, not what happens to the world when carbon dioxide is removed.
No, I don’t. You’re ignoring that replacing one with the other is an entirely fruitless exercise. Given what you say then in the short term replacing CO2 with methane will accelerate global warming even if it does dissipate faster and even at lower volumes. As such everything I said absolutely stands.You overlook the interdependence between CO2 and CH4
Certainly, there are known feedbacks incorporated into climate models. Melting ice over land or sea will change the albedo. Vegetation changes will affect albedo and soil moisture, therefore heat capacity.There is an aspect that is missing from that summary and that tends to get overlooked in general discussions about global warming. There are feedback mechanisms which amplify, sometimes in a linear relationship but sometimes exponentially, some of the factors involved in global atmospheric warming and climate change. I wonder if AI has learned this yet or is it still in the realm of HI (Human Intelligence)? I have begone to wonder when we humans will see the first scientific journal containing only articles written by machines and "peer reviewd" by machines.
You are making the mistake of thinking that there is some intelligence in AI.I suppose that a human could design an experiment or observational study and ask AI to draw the most logical conclusions. The next step would be to generate a paper. Perhaps AI could determine the nature of the next experiment. When it came to reviewing a paper you might have to find a totally independent review package. An interesting idea. What AI package would you trust to be independent? And how would you be sure?
Sadly AI parrots the gibberish that humans write online. It’s just a statistical engine.There is an aspect that is missing from that summary and that tends to get overlooked in general discussions about global warming.

Rather supporting my reservations about AI being the answer to the maidens prayer for weather prediction and justification for the festina lente approach by ECMWF and the Met Office.Sadly AI parrots the gibberish that humans write online. It’s just a statistical engine.
Not at all. Here we’re talking about LLMs it’s totally different than the AI used for weather.Rather supporting my reservations about AI being the answer to the maidens prayer for weather prediction and justification for the festina lente approach by ECMWF and the Met Office.
When it comes to climate it is providing a good synthesis of the combined knowledge of the IPCC, the best and most informed scientists in the world. The value added is in the presentation, obviously not in the content.
