How much of the IPCC report have you read? If temperatures are allowed to increase 5 or 6 degrees the changes would be catastrophic, even without considering the very real possibility of tipping points triggering run away climate change that would make the planet entirely uninhabitable. There's nothing dogmatic about it, this is our absolute best scientific understanding at this point in time. There are various hypot…
Even the special report on 1.5 degrees is super scary. I stopped taking the plane and became vegetarian just after reading it in 2019.

Re: For 110 years, climate change has been in the news
#92What is not being posted in news often enough are the options that we have to mitigate the effects. the only thing i read is that we need yo drive down co2. fact is: we are not gonna reach the targets in a reasonable timeframe. hence, we must start preparing to mitigate effects. instead we are caught by climate catastrophies like the current draught in europe, us and china and we are running around like headless chic…
> yo drive down co2. fact is: we are not gonna reach the targets in a reasonable timeframe. The solution to climate change is very cheap and simple. It is a carbon tax. It is also not difficult to implement at all and will cause only modest inflation. However, the oil industry is a huge influence on governments all over the world and will throw everything at preventing this from happening. Imagine for a moment that a…

The part I quoted isn't about Mitchell, and the article doesn't even quote Mitchell at all. It just reports what one of his studies concludes about temperature trends. I think you've yourself been misled. Mitchell accepted global cooling was really happening and the world was indeed cooling since 1940. See for yourself, here's one of his papers published in 1975: https://link.springer.com/chapter/10.1007/978-94-010-1…
> In balance, the net thermal impact of all global-scale pollution (including thermal pollution) is likely to be one of warming, perhaps increasingly so after 2000 A.D So Mitchell was right all along! What is this so called "contradiction" that you are talking about?
The main reason this is important is for the meta-level issue of what claims about consensus really mean. Newsweek didn't really care if the world got colder or warmer, they just wanted to sell papers. Mitchell wasn't misrepresented by the article nor me, as defrost claims. The article doesn't even quote him, it simply cites temperature data from one of his studies as a way to establish what trends existed at the time. Newsweek does so accurately because that's exactly what Mitchell's data did show, as my citation of his paper establishes. By Mitchell's own words, in 1975 the world had not only been cooling for decades but was still cooling!
Now defrost might argue that the Newsweek article was deceptive because, in fact, there was at least one scientist who rejected the "ice age doom is imminent" consensus as irresponsible. Indeed, claims about consensus are always very dubious for that exact reason, it's so rarely true. By 1975 there were certainly more than just Mitchell! But a Newsweek reader of the time couldn't have known that. They were being told that scientists in general believed in global cooling. Indeed nobody could deny the world was cooling, as that's clearly what the facts showed, so you'd have been a cooling denier if you'd said otherwise. If anyone had objected by raising Mitchell as a counter-example they'd have been told he was fringe, that his theories were outside the mainstream, that he was delaying action to prepare for the ice age and that even he accepted long term global cooling was real!
It can all be very confusing because to learn anything from this, you have to learn to doubt what you "know" is right based on what a handful of people have told you other people believe. Which is hard! But there's an even more confusing meta-level issue. Look at modern graphs of temperature:
https://climate.nasa.gov/vital-signs/global-temperature/
Look at the period between 1940 and 1975. The cooling Mitchell was writing about, that Newsweek, the New York Times, the Washington Post, that so many academics researched and reported on, that governments funded investigations into, that people proposed covering the Arctic with coal dust to fight - it's gone. The graph is flat. According to modern climatologists the cooling trend Mitchell was trying to explain with volcanos never existed at all ... and anyone who says otherwise is a malicious liar.

The 50s and 60s were also full of reports on global cooling. Temperatures started dropping from the 1940s by the data they used back then (these days that fall has been edited out). But there's a deeper problem with the point you're trying to make here. You claim the reports didn't reflect the scientific consensus. Really? Go read those reports. They do claim they were reporting the consensus. To the extent they admi…
> So how do you know that reports back then were lying about the existence of a consensus, but today's reports aren't? Doch[0]. Todays newspaper reports are also generally disconnected from reality. To illustrate with a tech news story as this is a tech news site, I saw one news story about the Raspberry Pi which had more errors than sentences, including the price, the OS, the RAM, the processor, the country of manuf…
I don't actually care about the social dynamics of scientists, because since the start of COVID I've developed a strong cynicism about all academic reliability, and so really wish that No True Scientist type arguments would go away. They're boring and even if an academic consensus did exist (it doesn't) I wouldn't care anyway.
But look at my other top level post in this thread. It makes two points. One is a technical point about ECS ranges. The other is about the way the article tries to make it seem like there's been a century-long consensus of scientists. The first is more important, but the replies and arguments are all about the second. Nobody seems to care about ECS. They're all about what some random guy whose data was cited in an article thinks, and whether I'm trying to deliberately mislead people.
So, arguments about what scientists as a group do/did believe are unavoidable because so many people have developed extreme views like Net Zero on the back of reading in the Guardian that all scientists agree on . You can argue about the scientific details of the claims, and that's really important, but it's of limited use because most people aren't basing their views on science anyway. For people who say look, just give me the 10 second summary of what the experts think, the only thing that can shift their view is by showing that the experts actually aren't expert at all.
The global cooling thing is therefore important, not because people aren't allowed to be wrong or change their mind - they are and they can - but because when that happens on a large scale, we'd expect to see some sort of post mortem where they collectively study why so many bold predictions were made that they later recanted. No such reflective learning process has ever happened. This raises questions about how genuine their expertise really is. Instead, as I and others document elsewhere, what they actually did is try to rewrite the past to claim global cooling was never a thing at all. They even edited temperature graphs to erase the cooling entirely. Then when it's pointed out that this isn't true using archival evidence, the claim changes to be that journalists were - inexplicably, as a group - engaged in a vast conspiracy to s/warming/cooling/g in everything scientists said. This claim is implausible, it's also literally a conspiracy theory, except one with no motive and no proof that it's real.
So yeah it'd be great to talk about the science more but there's little appetite for it here. They want to talk about social dynamics.
W.R.T. virology, how many virologists objected to the famous Lancet Letter in which dozens of scientists said "We stand together to strongly condemn conspiracy theories suggesting that COVID-19 does not have a natural origin ... Scientists from multiple countries .... overwhelmingly conclude that this coronavirus originated in wildlife"? Zero? One? A consensus of people and institutions like that is worthless.

You realise the nuance is in blaming where the methane production is coming from as well as the c02. There's a huge amount of shifting the "who is going to take any responsibility" which has made this pointlessly political and just wastes time and effort. This isn't helped by certain parties "reviewing" scientific data until it's massaged into narratives that they can push. (Again on all sides of whatever political s…
> has made this pointlessly political and just wastes time and effort No, making the topical "political" really mean partisan and it's not pointless. It's a deliberate tactic to stifle conversation and delay changes of policy. There are enormous financial benefits for many companies in delaying the adoption of sustainable economy.

This just makes the problem worse because little remember this 30 years later and think you're a liar or idiot because you pushed exaggerated claims. In the 80s in the UK acid rain was hyped up, in the 90s it was 20 years of oil reserves in the education system. Both now have generated adults distrusting education because they're not an academic and they just remember what a fool told them at face value without nuanc…
Acid rain was hyped up because it was a real problem and was fixed by tighter emissions standards[1]. Same with the ozone layer hole, an issue I heard a lot about as a kid, which was fixed by regulating CFCs[2]. These are examples of successfully tackling an issue and largely solving it, not "panicking over nothing".

This default reactive stance causes pointless arguments and discussion as I'm trying to demonstrate.
Yes there were 200% valid concerns. But this lead more to something close to hysteria than actual communication.
These concerns turned into teaching kids that the environment is going to die. The "unless nothing changes" gets lost in the discussion with 90% of non science teachers. In the same way that "emmissions have fallen" is on page 23 and is not front-page news.
The net result of this, although well intended. Is that most people are taught the headlines which turn into "watch out for acid rain". And now 40 years on they are even more confused and distrusting given the inconsistent messaging around this.
(News flash the oceans are still getting more acidic, almost no effort has been made here imo, but I digress)
Bad communication on these topics is more dangerous than not getting public approval. Bad communication around fossil fuels spreads distrust on the topic of conversation. (Again I remember well meaning teachers saying fuels would dry up by 2010 when I was in school)
Bad communication on climate change or global warming (notice how they don't use that latter phrase in outreach now) causes distrust here. Same goes for healthcare, 5G and the list goes on.
There will always be people who disagree. Trying to reach 100% is also futile. The communication should be straightforward clear and consistent and it's falling short of that by a long way.
The "just trust the science" is exactly the same call to authority as "this book says throw them off buildings". It helps nobody. But it happens at _all_ levels of outreach and bad education because people get afraid to say "good point, I don't know".

Are you aware that acid rain problem was solved by regulatory action? It didn't automatically disappear.
I have a strong educational background and a head on my shoulders. However from the mainstream public perception it just "disappeared one day" and transformed into "fossil fuels will be gone" which turned into "global warming" which is now "climate change".
This is obviously complete nonsense to anyone with a science background but is the result of decades of broken outreach combined with poor public education.

I wonder what it is that people actually want? That's the part I can never figure out, and they never seem to be able to articulate, at least truthfully. Like, I'm fine to say that I'd be OK to see this planet burned to the ground once I've had my fun with it. I mean, I feel a bit sorry for the humans who might come after, but that's a problem I'm not going to contribute to, so whatever. This seems to be the mainstre…

Unfortunately I'd have to agree with the original author here.
People gest and make empty vacuous statements on social media _a lot_. People are also unwilling to change or take on a small amount of responsibility. These 2 things are in direct conflict.
Again my strongest condemnation of this is people only now care about power and fuel efficiency at a large level now that Putin has caused the price to rise. Putin by his actions in the last few months has done more to sway public ACTION here than 30 years of social media posts and politicians. This is a damning sad statement on how much people honestly care about impacting change in the world.
