There is a lot of research on how various feedbacks influence the hydroxyl concentration. I recommend an AI search.

Doomerism at the End of the Universe
It’s a tough time to be a doomer.
Doomers are acutely aware of the planet’s acclerating collapse and ongoing sixth great extinction. This includes record-breaking fires, floods, heatwaves, storms and dozens of other human-caused impacts that are creating suffering for life around the planet.
We are exhausted by the volume of information we ingest: that it’s happening faster than expected, it’s worse than expected, ‘everything will be fine’ once we reach net-zero, we’re still within the models, that an ‘anthro-shift’ will save us, that the heat will kill us first, that a tipping point has tipped, and that we can avoid a climate disaster if we vote for the right people.
We are sickened by the political hard turn to the right that has seen the rise of kakistocratic fascism, wiping out access to years or decades of scientific research that allow humanity to track the trajectory of this beautiful planet’s collapsing systems.
We are grieving the loss of a treasure-triad of doomer voices articulating collapse, including Gail Zawacki, James Lovelock and Michael Dowd.
And doomers are bone-tired weary of the continued strawman assault on ‘doomism’ and ‘doomerism’ by otherwise important climate voices, including Michael Mann, Katharine Hayhoe, Hannah Ritchie, and most recently, Genevieve Guenther.
The assualt by Guenther in question appeared in The Guardian.com on June 24, 2025, and was titled, “This is a fight for life’: climate expert on tipping points, doomerism and using wealth as a shield.” This interview has some deep insights by Guenther that would ordinarily be ground zero for how a doomer might describe the current polycrisis. For example,
“it is bananas to feel reassured by that because 3°C would be a totally catastrophic outcome for humanity. Even at the current level of about 1.5°C, the impacts of warming are emerging on the worst side of the range of possible outcomes and there is growing concern of tipping points for the main Atlantic Ocean circulation (Amoc), Antarctic sea ice, corals and rainforests.”
“If the risk of a plane crashing was as high as the risk of the Amoc collapsing, none of us would ever fly because they would not let the plane take off. And the idea that our little spaceship, our planet, is under the risk of essentially crashing and we’re still continuing business as usual is mindblowing.”
“The idea that climate change will just take off only a small margin of economic growth is not founded on anything empirical. It’s just a kind of quasi-religious faith in the power of capitalism to decouple itself from the planet on which it exists.”
Ordinarily, I would be applauding this interview. However, towards the middle, Guenther took a dark turn towards doomer-bashing. In doing so, she placed herself firmly in the category of academics who are willing to make stuff up just because it must be so.
I know this group very well. As a retired professor of mathematics and computer science, I might deliver a lecture and then tell my students at the end of the hour that, “I may have just made everything up, it’s up to you to figure out if anything I said today is true or not.” My experience is that in casual conversations, discussions and lectures, some academics make stuff up. They do it to tease, to invite, to win, or most frequently, because it just must be so.
Indeed, I even wrote a poem about making things up. See if you can tell where the facts end in this one: How to win an argument: lesson #17.
Genevieve Guenther’s PhD was in Renaissance literature (2004, University of California, Berkeley). Her first book was “Magical Imaginations: Instrumental Aesthetics in the English Renaissance.” She has no acadamic credential in sociology or in climate science that I could locate. Nevertheless, as an academic with a credential from a top university, she, like myself and many of my elite colleagues, is entitled to just make stuff up.
And so, here are three categories of doomers she identified in the interview:
-
- One [type of doomerism] is the despair that arises from misunderstanding the science and thinking we’re absolutely on the path to collapse within 20 or 30 years, no matter what we do.
- Second, there’s a kind of nihilistic position taken by people who suggest they are the only ones who can look at the harsh truth.
- Finally, there’s the doomerism that comes from political frustration, from believing that people who have power are just happy to burn the world down.
If this classification is based on any type of research, and just not made up, then there are three different ways she could have come to know these categories:
First, maybe Guenther conducted a study, where she interviewed dozens of doomers and asked them some key questions that allowed her to identify these categories. I imagine she then submitted her research to a peer reviewed journal, where it was published, or is pending publication. Maybe it’s just a white-paper. If so, I am sure she could provide a link to her research.
Second, maybe Guenther is quoting an already-published peer-reviewed research article and she just forgot to cite the article in the interview. If so, I am sure she could provide a link to this research.
Finally, maybe this is preliminary research, where she had lenghthy discussions with social scientists studying the topic, and she is quoting what will eventually become published research. If so, I am sure she could provide references.
Just in case, here’s a question for you Dr. Guenther. To which category do the following doomers belong? Thomas Malthus? William Catton? The Club of Rome? William Rees? Michael Ruppert? David Wallace-Wells? Roger Hallam? Yes, Roger Hallam, the man who was sentenced to five years in prison for trying to save humanity from the impacts of climate change. When asked to name a doomer, any doomer, Hannah Ritchie named Roger Hallam.
But, given that this website is the Climate Casino, I’ll give 10-to-1 odds that there is no research article identifying these classifications of doomers, that it never existed, that it is not in progress, that it will never exist, and that she is making it all up, because it just must be so.
I am not going to bother with refuting Guenther’s categories of doomers; they are ignorant and non-sensical. They show that she has had very little involvement with the doomer community, and instead has decided to stereotype doomers based on casual observations of social media posts with little regard for the history or philosophical evolution of the community. I could not place a single doomer I know into any of the three categories. Guenther has created a peg board with a round hole, a square hole and a triangular hole in it, and doomers are real humans with complex emotional lives who are doing the best they can to cope with the inevetable collapse of global industrial civilization and ongoing sixth great extinction.
As uber-doomer Sam Mitchell stated for his authoritative take on classifying doomers, “If you ask 12 doomers to define what it means to be a doomer, you will get 13 different definitions.” And that certainly describes me. Every single day, depending on events in the world, events in my personal life and maybe what I ate for breakfast, I may have a different definition. I did my best to articulate all of this in my article, “On Being a Doomer.”
Meanwhile, Sam’s definition is usually less nuanced: “we are totally fucked.”
Back to the topic at hand. I posted Guenther’s quote to my Blue Sky account and have been more than impressed by the sheer volume of thoughtful and insightful responses. Here are a few of my favorites:
While there are notable doomers who take extreme positions on the near-term future of humanity and see little purpose in any type of environmental action, there are also doomers who are fundamentally environmentalists. The former may seek shelter in a small community of like-minded companions in some far-away off-grid location waiting for the apocalypse. The latter may believe in doing everything they can wherever they happen to live to leave the planet as healthy as possible for whatever comes after humans. But most doomers live ordinary lives and carry on with life as best they can, because what else is there to do?
Guenther would be better suited going after the three types of people who visit McDonald’s or the three types of people who drink non-alcoholic beer. I am sure there is a lot of mileage to be made in making stuff up about these groups.
For me personally, my formative years were in the late 1960’s and early 1970’s, at the height of the US environmental movement. My personal doomer life began in about 1981, after Ronald Reagan was elected president. Then Reagan removed the solar-panels from the White House and environmentalism as I knew it ended. Old-school environmentalism has never recovered. It won’t recover. Old-school environmentalism has been consumed by the profit-motivated big-green, EV, solar, wind, keep civilization growing at all costs, more stuff, humanity-first above all other life, death machine.
Dear Dr. Guenther, please stop. Just stop. Knowledge is good. Information is good. Action is good. Bullshit from a first-rate academic is bad. And modern industrial civilization is a cancer that is killing this planet. You’ve just got to get your priorities straight: humans or everything else. I’m on the side of everything else.

Thank you. Good words and sentiments well put. Brought some solace to me.
I’m with Sam Mitchell…#WeAreTotallyRoyallyFuhcked…Sadly, but truly…
Excellent Eliot. Thanks. And you used exactly the correct number of commas.
Perfect.
Yes every single butterfly matters! I save crabs. Thx for articulating so accurately our doomer predicament!
I agree Guenther ignored the priceless value of the non-human Life of this thin biosphere. We indeed grieve the 6th extinction. May I add that indigenous peoples are apparently non-human; colonialism continues at rapacious pace. In Canada we have a Supreme Court ruling from 1997 called the Delgamuuku decision. It guarantees the indigenous right to procure sustenance from the land. Yet zero tribes can survive off their devastated lands.
Five days ago our new “Liberal” Prime Minister Colonizer Carney rammed thru legislation that strips indigenous people of their right to refuse resource extraction on their land. Then yesterday, Carney’s announcement that critical minerals will go to War weapons not to renewable energy.
I must drag grieving self to continue to organize protests and fundraise for our Conservation movement. Must hide doomerism to provide false hope to protesters especially the youth. Solidarity with you and fellow doomers!
I think a lot of the academia attack on doomers is simply fear.
Not fear that we were right.
But fear that if we were right, and the evidence points that way, then that they will lose their privileges – nice salary, nice working conditions, nice house, blah blah. I know climate scientists don’t get paid a lot compared to CEOs of oil companies and politicians, but it’s hardly an uncomfortable life.
Always bear in mind this quote:
John Kenneth Galbraith
“People of privilege will always risk their complete destruction rather than surrender any material portion of their privilege.”
It was true of the Romans, it’ll be true for all those that live on the bounty of modernity.
Awesome as ever ☺️
Good to see Gail’s name. Miss her.
likewise, malcolm!
gail even drew a certain friend of hers known as “nicolas bourbaki” into a small fb group she adminned a few years back 🙂 RIP gail.
We live in a time where delusions are replacing reality and Mother Nature is, of course, the ultimate reality against which all knowledge must be tested. Now, AI is threatening to make our increasingly tenuous grip on reality even less secure. As we continue to produce 168,000 more humans daily and correspondingly increase our consumption of natural resources, the situation for the survival of any possible future generations is ever more in doubt. This is “Doomerism”, is it not? So, we are talking about the simple truth, but in an increasingly Fascist political environment controlling the mass media, as it feeds the corporate drivel so necessary for the continued accumulation of ever more wealth among the 890 billionaires in the US alone. Little wonder that “Doomerism” is under attack and the truth of climate collapse is being suppressed. Thank you, Eliot, for your efforts on behalf of truth telling, especially regarding our collapsing natural environment. You/we are NOT alone! NO KINGS, NO DICTATORS, NO TRUMP.
Well said, Eliot. Thanks for calling this out and for clearly articulating both the flaws in her statement and the reality.
I’ve had a very “productive Saturday” thanks to this post, your Happy Hour, and the many rabbit holes they have led me to. You are a valuable resource in the Doomiverse and a leader just by being you.
Considering myself a Doomist Prof. Eliot Jacobson, after reading your article on Genevieve Guenther’s three categories of Doomers whilst I’m sat under a sunshade taking in the sea view from my Mediterranean villa, watching all the yachts under sail tacking about whilst at the same time enjoying a snack of foie gras pâté and Beluga caviar on slices of artisan crusty bread, and all helped down with a couple of bottles of Château Pétrus, Pomerol 2010, I was going to give my take on categories of Doomerism in particular ecological Doomerism, but the wine having just produced its desired effect I don’t now give a f❤️uck, and so the best any of us can do is to get out and about and enjoy the sunshine and the fruits of the flora and fauna (dead or alive) on this planet, whilst we still can.
Good article Eliot. I still go with Sam Mitchells brilliant two class system for defining collapse aware people. Nazi doomer & doomer pussy. LOL, Sam’s the best.
This Guenther idiot just recently got on my radar and now I see her name everywhere.
As you’ve already shown, Dr Genevieve Guenther is a clueless fucking moron. And she’s a dime a dozen. Even when I was a Daniel Quinn loving doomer pussy, I still knew more about our predicament than this bitch will ever know.
She reminds me of Naomi Klein. Yes, good intentions, but so deep in denial and human supremacy that they end up causing more harm than good. STFU and get out the way… they will never understand what is needed to be understood.
Hell, they can’t even grasp basic energy transition 101… that every new energy source just gets added to the pile, and the old sources end up being used more than they were prior to finding the new source.
I think my hatred for these ass clowns is so strong because most of them have a decent background with the other stuff… overshoot, collapse of prior civilizations, man-made climate, capitalism, human history, etc… In other words, they should fucking know better. At least the dumb ass normies who think we are gods gift to the universe… at least they can fall back on the excuse of pure ignorance.
I fully believe that intuitive people very often outshine academics. You don’t need a degree to see the writing on the wall!
Disagree.
This is chef’s kiss excellent as always Eliot.
Nice to see Gail Z. getting a mention. My favourite doomer (or themist – as she slightly preferred; some of us tried to come up with another term and settled on that one).
She wrote about it here (I supplied the poem at the end, back when I was still composing parodies of popular songs; I’m still quite fond of that one!).
Michael Dowd even showed up in the comments to debate her. I miss them both.

Capitalists and their scientific community beneficiaries are much threatened by growth caused resource depletion. They are reacting irrationally in panic; postmodernist sophistry is a strategic coping mechanism they are now using to convince the consumer class and themselves that factual reality is inconsequential. Postmodernist gaslighting.
Because ” doomers” are rooted in reality, the powerful growthists have backed and unleashed an army of propagandists to convince the consumer class to just keep shopping.
