This week's This American Life was a very good climate change episode. Somewhere in this thread at some point (california wildfires?) someone mentioned that the quickest way to turn a liberal town libertarian is to bring up Managed Retreat, and that's exactly what the long second story is about. A woman in Pacifica California loses her back yard because it falls into the ocean, but the real estate interests get the whole town up in arms about how the government is going to steal everyone's homes.

https://www.thisamericanlife.org/762/apocalypse-creep

It was a good episode, but did leave me with that sinking 'what do we do' feeling, particularly the second and 3rd segments. I'm moving from the UAE back to the US this summer and climate change is on my mind frequently in the process. While there has been some frustrating reading the past few pages, I do like how this thread often helps point away from spiraling about feeling futile about all of it.

Gonna try to lobby to make the place I live more walk, bike, and bus-friendly. Gonna stock up on stuff for emergencies and start building community support networks wherever I land, and figure out the rest from there as the disasters unfold.

Since scientists have consistently been under-performing in their estimates and projections, we can probably expect a one foot sea level rise by like 2035 or 2040.

I'm sorry, but no, scientists are not "consistently wrong about everything". They are the people who are doing the most to inform us about the dangers of climate change, and in fact the only reason we know about climate change at all. It is uneducated laymen who treat climate more as a political than a scientific issue who are consistently wrong, and frankly mature adults should know better than to make sweeping dismissals of science like this.

The only possible reason you could think the best response to a report on sea level rise is to say "actually, I expect sea levels to rise much faster than this" is because you think the report is wrong.

Would you care to share some of these open acknowledgments? Because this has not been my experience with climate science at all. Scientists of course will acknowledge all sorts of limitations to their studies but I don't know anyone who thinks that the work they are doing is fundamentally flawed and hopelessly biased in a pollyannish direction. In fact, I have a sneaking suspicion you are not getting these views from asking questions at climate symposia or reading model writeups, but rather from editorials like this one from the NYT. This was widely panned by climate scientists who vociferously objected to the author's (a climate journalist's) characterization of their work. I'd like to repeat some of their objections, collected here at Climate Feedback.

quote:

The main flaw in the author’s argument that scientists have “underestimated” the rate and severity of climate change is that the author predominantly points to recent extreme events as evidence of what scientists “failed to predict” (such as the heat wave that extended into the Arctic and drove rapid melting of the Greenland Ice Sheet or recent hurricanes).

quote:

n my view, this article misrepresents the history of climate science (in particular, what was known from the 70s to 90s) to try to make up a case that climate scientists “got climate change so wrong”, i.e., completely underestimated its pace and amplitude. I found numerous factual errors and mis-interpretations in this presentation. The reality is, since at least the 80s, climate scientists have been making broadly consistent projections (to whomever was listening). The observed pace of warming is on par with these projections—not faster. What’s true is that some impacts of that warming are happening faster than initially anticipated.

quote:

Most of the specific facts and statistics in this op-ed are correct, but the overall effect is significantly misleading. The author’s central point is that scientists have been drastically underestimating the scope and the pace of climate change until just the past decade or so, and recent events such as permafrost melting, ice cap loss, and extreme weather events have caught them by surprise. This is simply not true.

quote:

I agree with Alexis Berg regarding the overall premise of this piece. Overall, climate scientists’ predictions have, on average, been roughly correct for quite a few decades now. This opinion piece by Eugene Linden seems to selectively present historical predictions that turned out to be underestimates, while ignoring those that were right-on or even overestimates.

Do these seem, to you, like the statements of people who agree with you that "scientists have consistently been under-performing in their estimates and projections"? Sure doesn't to me. And this is just a taste. I'd love to see who in the climate community you're talking about that really does think the whole thing is a gigantic underestimate, because as I've said, I have literally never heard it.

You seem to have not heard of a lot of things with recent climate science. I'm not going to dox myself, but former colleagues of mine in climate science and related fields tend to think we are underestimating rapidity and magnitude of changes. We also fairly consistently have underestimated climate change, because the shorter-term feedbacks have been overwhelmingly positive, leading to a tendency to systematically under-estimate.

Vision prize do polls on climate scientists and this old survey shows the consensus at the time was that the 2013 IPCC was too optimistic on sea level rise over the current century.

http://poll.visionprize.com/#ipcc-too-optimistic

I can't find it now but I've also read statements from climate scientists saying the IPCC under-estimates climate change. It's a bit of a self selection bias, if they are too realistic policy makers consider them doomers and are more likely to ignore what's being said. So by necessity to have policy makers (politicians) listen to the results they have to be cautious in how they present it.

That's not to say the experts working on the IPCC reports are lying, they are being pragmatic in how they present the findings.

1) You apparently have no memory of extensive conversations that have taken place in this thread over the better part of a decade on the climate research community griping about the handcuffs their findings and models are placed within for the purpose of avoiding alarmism in AR reports

2) you apparently have no memory of any of the myriad symposia that have been linked here over the years that include QA sessions involving researchers talking about their research and specifically addressing the question of why underestimation happens, openly

3) you apparently have no memory of any of the reporting that has been linked here over the years regarding climate scientists talking about underappreciation for tertiary effects, unknown tipping factors, in general the fact that the Earth is a complex loving machine.

No climate model researcher defends their model in the terms that you are making them out to here, which is a GIGANTIC red flag and is one of the primary reasons that I am so aggressively telling you to gently caress off. models are assembled and defended in very complex statistical terms, the degree to which their work is defensible against paleoclimate information are limited and researchers know that and say it up front. It is never presented hard and fast like you're making it out. You are confusing the certainty of atmospheric metrology versus research on direct forcing factors and first order effects versus more complex models with secondary order effects, hypothetical tipping points, novel included factors like modern and paleo land ice loss, etc.

Like, I seriously cannot think that the above was posted in good faith, because

https://www.vice.com/en/article/43e8yp/the-uns-devastating-climate-change-report-was-too-optimistic

quote:

NOT ALARMIST ENOUGH

But there are fault-lines in the IPCC report. Among them is that its dire warning of coming catastrophe, though devastating, could well be conservative. A number of scientists point out that the report fails to fully acknowledge the role of amplifying feedbacks as highlighted by Hansen.

“Even with its description of the increasing impacts that lie ahead, the IPCC understates a key risk: that self-reinforcing feedback loops could push the climate system into chaos before we have time to tame our energy system, and the other sources of climate pollution,” Mario Molina, who shared the Nobel prize in chemistry in 1995 for his work on depletion of the ozone layer, told The Guardian.

In an essay for the Bulletin of the Atomic Scientists, Molina along with Veerabhadran Ramanathan, a professor of climate sciences at the University of California, San Diego, and Durwood J. Zaelke, president of the Institute for Governance & Sustainable Development in Washington DC, explain that climate change is not worsening in a simple, linear fashion, but rather by compounding and accelerating: :siren:“Adding 50 percent more warming to reach 1.5 degrees won’t simply increase impacts by the same percentage—bad as that would be. Instead, it risks setting up feedbacks that could fall like dangerous dominos, fundamentally destabilizing the planet.”:siren:

The IPCC “fails to adequately warn leaders” about six climate tipping points that work in this way. One of the more well-known such tipping points is Arctic sea ice, which could disappear in the summer in just 15 years, according to the Arctic Monitoring and Assessment Programme’s Snow, Water, Ice and Permafrost in the Arctic report. The ice acts as a reflector of heat back into the atmosphere, so the more it melts, the more the Arctic waters absorb heat.

This self-reinforcing feedback loop could lead to an ‘Arctic death spiral,’ where the loss of the sea ice accelerates the melting of permafrost, which some scientists believe could release large quantities of methane—a greenhouse gas 30 times more potent in driving warming than CO2—into the atmosphere.

:siren:Computer simulations of the Arctic’s thermokarst lakes—a certain type of Arctic lake that forms as permafrost thaws—are not incorporated into current global climate models.:siren:

I've seen no evidence to indicate that most scientists actually believe this is happening. It's been suggested, (or, maybe a better way to put it is "this accusation has been leveled"), but it's never really backed up by anything. Here's a good article on the subject by Gavin Schmitt, the current NASA climate czar. I've extracted the most relevant portion below.

quote:

The notion that scientists are so conservative that they hesitate to discuss dire outcomes that their science supports is quite prevalent in many treatments of worst case scenarios. It’s a useful idea, since it allows people to discount any scientists that gainsay a particularly exciting doomsday mechanism (see point #1), but is it actually true?

There have been two papers that really tried to make this point, one by Hansen (2007) (discussing the ‘scientific reticence’ among ice sheet modelers to admit to the possibility of rapid dynamic ice loss), and more recently Brysse et al (2013) who suggest that scientists might be ‘erring on the side of least drama’ (ESLD). Ironically, both papers couch their suggestions in the familiar caveats that they are nominally complaining about.

I am however unconvinced by this thesis. The examples put forward (including ice sheet responses and sea level rise, and a failed 1992 prediction of Arctic ozone depletion, etc) demonstrate biases towards quantitative over qualitative reasoning, and serve as a lesson in better caveating contingent predictions, but as evidence for ESLD they are weak tea.

There are plenty of scientists happy to make dramatic predictions (with varying levels of competence). Wadhams and Mislowski made dramatic predictions of imminent Arctic sea ice loss in the 2010s (based on nothing more than exponential extrapolation of a curve) with much misplaced confidence. Their critics (including me) were not ESLD when they pointed out the lack of physical basis in their claims. Similarly, claims by Keenlyside et al in 2008 of imminent global cooling were dramatic, but again, not strongly based in reality. But these critiques were not made out of a fear of more drama. Indeed, we also made dramatic predictions about Arctic ozone loss in 2005 (but that was skillful).

The recent interest in ice shelf calving as a mechanism of rapid ice loss (see Tamsin’s blog) was marked by a dramatic claim based on quantitative modelling, later tempered by better statistical analysis (not by a desire to minimise drama).

Thus while this notion is quite resistant to being debunked (because of course the reticent scientists aren’t going to admit this!), I’m not convinced that there is any such pattern behind the (undoubted) missteps that have occurred in writing the IPCC reports and the like.

Here's a good article on the subject by Gavin Schmitt, the current NASA climate czar. I've extracted the most relevant portion below.

Is there any specific reason why Thorn's post does not meet this demand? Have you found any data as I had requested before you elaborated further to support your initial thrust that the IPCC and similar agencies/persons are not in fact underestimating sea level rises? If you're not interested in providing that I don't think it is best you continue this, as if you have no argument I can only conclude you are just trying to create drama and will be forced to act accordingly.

We are past the point of demanding more and more evidence as you potentially ignore what has already been put forward, please respect the debate and discussion process and move on to the supporting arguments stage as the sides have been clearly delineated.

Who wants to tell this clown that there's a difference between RCPs and climate models, by the way

as I scroll back, it occurs to me that he immediately started blowing up about climate science but he might have misinterpreted the inciting issue (by barging in to other people's conversation, it should be noted) entirely

now you're stuck between deciding whether to spend some time googling a la :fishmech: trying to figure out what we're talking about and actually catching yourself up a little bit, or continuing your hard stance on asking thread to catch you up so that you can fishmech and weasel your way around every possible deliberate misinterpretation of every possible sentence

all this in a thread that usually showers new posters with information that somehow continues to lock horns against you

Do note that it remains your burden of proof to come to the table with evidence of why underestimation is not normal, by the way, as that has been the track across each report as time progresses Citation: quite literally every single IPCC report


:fuckoff:

That's your opinion. Now let's look at the actual IPCC reports. Here's a comparison of IPCC (and earlier) model projections compared to observed warming, provided by Carbon Brief.



Do we see a consistent track record underestimation of warming across each report as time progresses? Not as far as I can tell. The second and third report underestimated warming while the first, fourth and fifth report overestimated warming, and none of their deviations were particularly massive, almost entirely within a 95% confidence interval, and on average their combined estimations slightly is almost exactly on par. So you say there's this trackable, consistent underestimation, but when we actually go back to look at the data, it's just not there.

Don't trust the liberals,

Why are you showing predictions on warming when the conversation was about sea level rise?

Is this what they call moving the goal posts.

I honestly kind of wish I was audacious enough to link a table with enormous, swinging errors and then try to say that somehow it's not an example of enormous swinging errors.

^^^ Here I thought I was engaging with the motherfucker about RCPs, so I guess that's the part where I answered the field and where the goal posts were at the time. That makes sense as RCPs would be a component of any sea level projection derived from any particular RCP...

Jesus Christ the scope exploded.

I might eat a probation for this, but I actually cannot hold back being honest about how I feel in response to you just...seeing made up poo poo, everywhere:

I'm so sorry.

Actually would someone give me a sixer, I have dinner to cook and a house to clean, and just speaking for myself, that is completely correct when he says below that I have positively no interest in participating in the "Debate meeeeeee" Ben Shapiro routine

Yes, I've provided multiple links to statements by climate scientists that insist they are not systematically underestimating climate change. But I have to assume that doesn't count, or else you wouldn't be posting this.

Anyway, your demands are ridiculous and obviously only apply to me. No one else here, including the person who makes the original claim, is required to provide any data at all, (and they have, dutifully, not done so). You're contriving a reason to ban me, not for breaking any rules, but simply for expressing views (backed up ample citations) that "cause drama", and, well, I guess I can't stop you.

Because I am responding to a person who claimed that the models (which project warming) are "handcuffed" to "avoid alarmism". It's a pretty relevant point in context, because if they're handcuffed and are underplaying warming, why are they so spot on?
