Both can be true. It's true that western countries disproportionally use more energy and resources per capita than developing countries. It's also true that global human civilization is in an advanced state of ecological overshoot mainly because of overconsumption and overpopulation. We are currently consuming more resources than our ecosystems can regenerate naturally, we are operating beyond the earth's carrying capacity. On top of that we are dumping entropic waste back into the ecosphere in excess of nature’s assimilative capacities, which only speeds up the process of system wide ecological collapse that will absolutely lead to dramatic population contraction in the near future. In this sense, overshoot is actually the cause of climate change and numerous co-symptoms including plunging biodiversity, ocean acidification, tropical deforestation, landscape/soil degradation, contamination of food supplies, depleting aquifers, the pollution of basically every life-supporting system. Our contemporary growth obsessed technological civilization is literally consuming and polluting the biophysical basis of our own existence, and somehow we seem to think that there's nothing that can go wrong by adding a couple more billion humans on the planet.

Not according to even the scientists who otherwise agree that the future would be "ghastly", though?
https://www.frontiersin.org/articles/10.3389/fcosc.2020.615419/full > It is therefore also inevitable that aggregate consumption will increase at least into the near future, especially as affluence and population continue to grow in tandem (Wiedmann et al., 2020). Even if major catastrophes occur during this interval, they would unlikely affect the population trajectory until well into the 22nd Century (Bradshaw and Brook, 2014). Although population-connected climate change (Wynes and Nicholas, 2017) will worsen human mortality (Mora et al., 2017; Parks et al., 2020), morbidity (Patz et al., 2005; Díaz et al., 2006; Peng et al., 2011), development (Barreca and Schaller, 2020), cognition (Jacobson et al., 2019), agricultural yields (Verdin et al., 2005; Schmidhuber and Tubiello, 2007; Brown and Funk, 2008; Gaupp et al., 2020), and conflicts (Boas, 2015), there is no way—ethically or otherwise (barring extreme and unprecedented increases in human mortality)—to avoid rising human numbers and the accompanying overconsumption. That said, instituting human-rights policies to lower fertility and reining in consumption patterns could diminish the impacts of these phenomena (Rees, 2020).
Not to mention the more mainstream views like those of the IPCC (look at their population graphs).
SaxManSteve t1_j8mfa2n wrote
IPCC population projection models are often criticized for having simple assumptions. They generally model predicted population based on the expected rate of world GDP growth and the correlated predicted reduction in birth rates. They don't use a system dynamics based model, that could model the complexities of overshoot and climate change and its impacts on population. For example global warming will have varying levels of cascading non-linear effects on extreme weather events, things like increases in economic inequality, increase in domestic and international conflict, increase in state fragility, increase in pandemics, increase in population displacement and migration, decrease in ecological biodiversity, decrease in food, fuel, and water resources, increase in droughts and desertification of fertile land, increased fragility of global supply chains, ect..... None of these factors are part of the IPCC models, meaning that their predictions shouldn't be taken as realistic predictions of populations. Rather they should be seen as models that predict population numbers in a world where climate change and overshoot will have little to no impact on human civilization in the near future.
It's also no secret within academic climate science circles that the IPCC has long been politically motivated to underestimate the scale of the problem. Which is why very few climate scientists actually believe that the Paris Accord is realistic. We all know there is no chance the world can avoid 1.5 C mean global warming and that we will likely see a potentially disastrous 2 C increase by 2050. Many already assume that there will be no remaining carbon budget even for the 2 C target
The IPCC infamously fails to account for carbon cycle feedbacks and their associated tipping points when setting their own emissions targets. Meaning that even a 2C warming may well trigger irreversible runaway “hothouse Earth” conditions. In coming years, we will see an ice-free Arctic Ocean, more rapidly melting permafrost, methane releases, an increase in wildfires, and other short-term positive feedbacks that will put climate change on steroids.
Even in the best case, the world can expect more and longer heat waves and droughts, more violent tropical storms, extended wild-fire seasons, accelerating desertification, water shortages, crippled agriculture, food shortages, rising sea levels, and broken supply lines. Coastal cities will be flooded and some may eventually be abandoned. Many other cities are likely to be cut off from food-lands, energy, and other essential resources with the breakdown of national highway and marine transportation networks; this alone would make urban life untenable. According to the recent Environmental Risk Outlook 2021 (2021), at least 414 cities with a total 1.4 billion plus inhabitants, are at high or extreme risk from a combination of pollution, dwindling water supplies, extreme heat stress, and other dimensions of climate change.
From this perspective, it's absurd to even entertain the idea that adding 2+ billion more people on the planet in the next 20 years would be a good idea. We should be currently engaging in an international effort to reduce our current consumption, reduce our energy demand, reduce our birth rates, reduce economic inequality, and ultimately start to move away from a growth for the sake of growth economic model towards an ecologically sustainable economic system.
It's simply immoral and reckless to keep chugging along with the business as usual economic model. Doing so is to condemn billions of people to a brutish, painful and short life.

So, my original response got eaten by reddit's spam filter (probably because I included the same link twice, but you'll never know with these things) and I'm going to have to try again, for posterity.
By now, many of the points I made in that comment were already made by others, like Spratt & Dunlop possessing very limited credibility, or that feedbacks are both slow enough relative to human emissions to operate over many centuries and are already accounted for in the IPCC reports to a great extent. In fact, even IPCC report #4 - which was first published in 2007 - already had a whole chapter on carbon cycle and other feedbacks.
https://www.ipcc.ch/site/assets/uploads/2018/02/ar4-wg1-chapter7-1.pdf
The feedbacks which are more difficult to account for, like permafrost, still have an impact that's a fraction of human emissions.
I would simply like to reiterate the points around "crippled agriculture, food shortages", etc. It would appear true if you just look at the climate projections and assume that they'll apply to the current amount of land used to grow food. What that assumption misses is that the amount of land won't stay the same: the IPCC assumes that as the population grows and climate change accelerate, people will simply clear-cut down more, more and more forest to the tune of hundreds of millions of hectares and grow crops on that land. Compare the population/GDP graph from my earlier comment (not linking it again in case it also triggers the bot) with the land use graph, where cropland extent and forested land extent simply go in opposite directions in each scenario - to the point where a scenario with 12 billion people cuts down nearly 600 million hectares. This is also why food supply projections for 2050 look like this and like this, and not like what most people assume when only looking at yield reduction projections or the talk of instability.
And finally, yes, we should move to a non-growth and sustainable system. The thing is, it looks like we may well get away with not doing that in this century, even if the cost will simply be paid by the ecosystems and future generation. That is the position of the scientists who collectively wrote the "ghastly future" paper, and at this point, the counterarguments (whether optimistic or the opposite) appear increasingly strained.

Just to back up this point, r/science discussed a paper in Science which examined known tipping points 5 months ago. I extracted a list of those tipping points, their thresholds, their effects, and their timescales.
As you say, none of the near-warming (<4C) near-term (<200-year timescale) tipping points had significant global effects on warming or sea level rise.

That's an enormous number claims regarding what climate scientists believe, but the only source presented for any of it is a non-peer-reviewed report from an Australian think tank whose previous reports were criticized as alarmist, misleading, and lacking scientific credibility by scientist reviewers
And looking at the report itself, it's easy to see why. Their number 1 "critical understanding" cherry-picks only the IPCC scenarios which support their narrative:
> "Current (CMIP6) climate models project on average a warming of 0.3°C for the decade to 2030 (across the SSP2-4.5, SSP3-7.0 and SSP5-8.5 scenarios)."
By contrast, the IEA expects CO2 emissions to fall 15-20% by 2030, putting the world roughly in line with the IPCC's SSP1-2.6 pathway -- a pathway they totally ignore*.
It's reasonable that they would want to include higher-emission pathways as well to examine the danger of less likely scenarios, but to exclusively examine higher-emission scenarios and completely ignore lower-emission scenarios that are as or more plausible? It's clear cherry-picking of data to establish a chosen narrative.
On to their number 2 "critical understanding":
> "Due to model limitations, we will not know exactly how the climate crisis will unfold until it’s too late.6 One example is the failure to predict the intensity of extreme heat and flood events in Europe and North America in 2021."
i.e., they're conflating climate and weather.
One heat wave or one flood is weather; by contrast, climate is the broad long-term trend. Failing to predict a particular flood or heat wave no more "proves" the IPCC models wrong than a cold winter "proves" the climate is not warming. They're making an utterly unscientific argument here.
Not everything they say is wrong -- notably they're quite right that warming has already caused significant effects and even 1.5C (which is unlikely) will cause more -- but enough demonstrably biased and unscientific claims are thrown in that this report could never pass robust peer review and is not a scientific source.

It’s not so great for any of our existing economic systems though. Just like capitalism, socialism also relies on the right kind of population growth. Ie you need enough working adults to outnumber every other demographic. To keep this going, you need enough children. The reality is that the retired elderly is about to outnumber every other demographic. Our social safety nets in capitalism and socialism can only work if we can lower the number of retired elderly, or completely end programs like social security and Medicare.

Or maybe we can just let young people have fun and eat free for a few years, then ship them out to biodynamic farms where they can work the soil by hand, utilizing no machinery or chemicals until death. The middle -aged can pull hand carts carrying produce to urban markets. Everyone has their ration cards and gets to eat, but labor is divided such that everyone gets a chance to have fun to the best of their ability in the pain-free years of life, and graduates to working closer to the land. When death comes it is usually closer to agricultural fields or in them, so less work needs to be done to move the bodies to the compost piles that fertilize the fields. In this way we can avoid directly eating people, but we would all still be cycled into food via soil inputs. If we did it without violence and guns, it would be more like the Smurfs than the Khmer Rouge.

If the government and corporations wanted to force significant change that would allow everyone to live more sustainably, they could do it. But they don’t. And don’t tell us that biking to work and using paper straws will help, because we’re not the ones mass producing all this garbage for consumption.

Funnily enough, they don’t even mention the mega cargo ships, and I don’t know the number, but my logic says there are WAY more cargo ships then cruise ships.
Yes, I know less cargo ships would be used if the population didn’t want as much useless stuff so regularly.

Plain language summary:
A team of international scientists has published a study in Nature Communications which warns that if global temperatures cannot be stabilized below 1.8°C, the West Antarctic and Greenland ice sheets will be lost and sea levels will rapidly rise. The study states that this increase in sea level would be on top of other contributions, such as the thermal expansion of ocean water. The study highlights the need for computer models to capture all components of the climate, as well as new observational programs to accurately represent physical processes in the ice sheets. If global net zero carbon emissions cannot be reached by 2060, then sea levels will continue to rise by at least 100 cm within the next 130 years. This would be on top of other contributions, such as the thermal expansion of ocean water.

It's worth noting that this paper is actually good news, as it predicts lower global sea-level rise contributions from ice melt than previous models did; from the Abstract:
> "The combined effect is likely to decelerate global sea-level rise contributions from Antarctica relative to the uncoupled climate-forced ice-sheet model configuration."
In "Discussion" they call this out specifically for high-emission scenarios:
> "In our high-emission scenario model simulations that include parameterizations for hydrofracturing, ice-cliff instabilities, and capture sea-ice and atmospheric responses, the net impact of ice-sheet/climate feedbacks on SL rise is negative."
It looks to be a fairly marginal change, though; the projected amount of sea-level rise is still enough to be a serious problem, impacting where hundreds of millions of people currently live.

I'm a bit dubious about this; paleogeographic studies point to large (as in around 20m) sea level rises from the kind of temperature rise we've already seen or can project in a few decades. Now, it could be a matter of timing - it might take 1000 years or so for the full ice-sheet response - but it's not exactly reassuring.
grundar t1_j8nobbf wrote
> I'm a bit dubious about this
What exactly are you dubious about? That the paper predicts lower sea level rise than previous models, or that either way the sea level rise will be enough to have serious consequences?
Your phrasing makes it seem like you're disagreeing with me, but I don't see which part you're disagreeing with.
> Now, it could be a matter of timing - it might take 1000 years or so for the full ice-sheet response - but it's not exactly reassuring.
There's a massive difference between "20m of sea level rise in 80 years" and "20m of sea level rise in 1,000 years".
In particular, my understanding is that paleographic studies are generally of the form "temperature went up 5C and sea level went up 20m over the course of 10ky", meaning sustained temperature increase led to large sea level rise. There's not really any hope of seeing temperatures 80 years from now back to pre-industrial levels, but IPCC scenarios like SSP1-2.6 see temperature starting to fall by then, meaning it could be back to pre-industrial levels within a century or two.
As a result, if a certain amount of sea level rise requires only 80 years of sustained temperature increase of 1.5-2C, we have little hope of avoiding that. By contrast, if that amount of sea level rise requires 1,000+ years of sustained temperature increase of 1.5-2C, there's quite good odds of avoiding some, most, or potentially even virtually all of that.
In general, the known ice melt tipping points take thousands of years. I extracted a list of those tipping points from a paper previously discussed on r/science, and the timescale for 10m+ of sea level rise looks to be about 2,000 years (mainly West Antarctic ice sheet and East Antarctic subglacial basins).

Their estimate of SLR is the opposite of a conservative one, their estimate is at the upper range of previous estimates. Edwards et al. (2021) provided us with the most up-do-date results from the Ice Sheet Model Intercomparison Project (ISMIP6) for Coupled Model Intercomparison Project Phase 6 (CMIP6).
From Park et al. (2023), this paper,
>For the SSP1-1.9, SSP2-4.5 and SSP5-8.5 scenarios the GrIS contributes about 12 ± 1, 18 ± 0.9 and 23 ± 1.6 cm and the AIS adds 3 ± 0.8, 7 ± 1.4, and 15 ± 1.5 cm to SL by the year 2100 relative to pre-industrial levels (Fig. 2c, d). 2100 CE (2150 CE) LOVECLIP simulates for the respective scenarios a total ice-sheet contribution to SL of 15 ± 0.9, 24 ± 1.3, 39 ± 2 (19 ± 1.4, 48 ± 1.4, 136 ± 6.2) cm (Fig. 2b).
Compare this to Edwards, from Table 1, which reports median and 5th-95th percentiles, under SSP5-8.5 by 2100, the GrIS contributes 10cm [2,20], the AIS contributes 4cm [-4,14].
Note however, that Park is reporting SLR from pre-industrial, while Edwards is reporting post-2015 SLR, which means you would need to subtract the pre-2015 contributions for a complete comparison. This would have the effect of subtracting less than ~1cm from GrIS, and ~2cm from AIS in Park.
In fact, the AIS contribution found in Park is closer to the median in Edwards' worst-case "Risk-averse projection" which combine assumptions that lead to the highest AIS contribution.
In short, this paper's results for 21st century SLR are from from "conservative" in the sense that they actually fall within the upper range of probability of previous research. They themselves note,
>The GrIS and AIS contributions lie within the range of estimates obtained from uncoupled scenario-forced models for Greenland and Antarctica
Edit: A previous version of this comment was in complete error, mea culpa!
BurnerAcc2020 t1_j8mbcxg wrote
No, I have to say that you misread the paper here.
The first sentence you quoted discusses estimates for the 21st century (i.e. up until 2100), and it explicitly refers to AIS (Antarctic ice sheet) contribution. The actual paper's estimate in the second sentence is by 2150, not 2100, and it refers to ice-sheet contributions - i.e. Antarctic ice sheet and Greenland.
You need to look at Figure 3 of that paper. You'll see that in d), their estimate for AIS alone under SSP5-8.5 (the orange line - the higher yellow line is a more primitive simulation of the same scenario they run for comparison) is about 0.2 m by 2100 and 0.7 m for 2150.

So, fun fact, there are places where sea level is remaining neutral or even gently receding.
The part that goes along with this, however the deniers wanna gloss over it, is that there is also significant crust uplift going along with it. Since we measure from our shore markings this looks like it’s going ‘down’ in some places despite overall sea level continuing upwards.
Kalapuya t1_j8ki2iq wrote
Sea level rise is not linear and is not rising uniformly or at all in some places. Many places are experiencing zero or even negative sea level change. This variance can occur even on a kilometer-by-kilometer basis. It is primarily driven by changes in ocean currents, wind, sea surface temperatures, and tectonic and other hydrological dynamics.
On the Oregon Coast for example, some low-lying areas will likely experience 12-18”+ of SLR by 2050. Other areas (primarily in the south), are undergoing rapid tectonic uplift that will outpace sea level rise until at least the mid 2030s, and may experience few impacts because of the high continental freeboard.
These systems are highly dynamic and variable, but it is clear that overall global sea level is rising on average at a MUCH higher rate compared to the historical record and will lead to costly impacts for many communities.
midclassblues t1_j8kdrli wrote
There are plenty of sea level gauges around the United States, some having been in operation over 100 years. NOAA has analyzed these quite a bit and they show some sea rise over the years. I estimated an 8 inch rise at Key West over 100 years based on their data.
I believe the point of all these studies is not to look at what happened, but what will happen well in to the future. The past 100 years is not a good way to estimate future changes in the ocean. That's not a good retort, but the biggest changes have not happened yet. A 6" rise in the last 100 years is still not insignificant.

Studies show that even warming of over 4 degrees by the end of the century (which is higher than what is now expected) reduces ocean biomass by about 20%.

Under a worst-case scenario (RCP8.5, Fig. 2b), 84% of statistically significant trends (p < 0.05) projected a decline in animal biomass over the 21st century, with a global median change of −22%. Rapid biomass declines were projected across most ocean areas (60°S to 60°N) but were particularly pronounced in the North Atlantic Ocean. Under a strong mitigation scenario (RCP2.6, Fig. 2c), 68% of significant trends exhibited declining biomass, with a global median change of −4.8%. Despite the overall prevalence of negative trends, some large biomass increases (>75%) were projected, particularly in the high Arctic Oceans.

https://www.nature.com/articles/s41558-021-01173-9
>Mean projected global marine animal biomass from the full MEM ensemble shows no clear difference between the CMIP5 and CMIP6 simulations until ~2030 (Fig. 3). After 2030, CMIP6-forced models show larger declines in animal biomass, with almost every year showing a more pronounced decrease under strong mitigation and most years from 2060 onwards showing a more pronounced decrease under high emissions (Fig. 3). Both scenarios have a significantly stronger decrease in 2090–2099 under CMIP6 than CMIP5 (two-sided Wilcoxon rank-sum test on annual values; n = 160 for CMIP6, 120 for CMIP5; W = 12,290 and P < 0.01 for strong mitigation, W = 11,221 and P = 0.016 for high emissions).

>For the comparable MEM ensemble (Extended Data Fig. 3), only the strong-mitigation scenario is significantly different (n = 120 for both CMIPs; W = 6,623 and P < 0.01). The multiple consecutive decades in which CMIP6 projections are more negative than CMIP5 (Fig. 3b and Extended Data Fig. 3b) suggest that these results are not due simply to decadal variability in the selected ESM ensemble members. Under high emissions, the mean marine animal biomass for the full MEM ensemble declines by ~19% for CMIP6 by 2099 relative to 1990–1999 (~2.5% more than CMIP5), and the mitigation scenario declines by ~7% (~2% more than CMIP5).
In fact, it was estimated a year ago that a mass extinction in the oceans would happen only if the emissions somehow continue to shoot straight up for 300 years. In fact, even that scenario, which would result in about ~12 degrees of warming, would "only" drive about 40% of the species in the ocean extinct. -
