How conservative was the old model? 100 times faster doesn’t seem right if the old model was accurate for Antarctica. Is there any way I can see the source of this study?

It’s sad. We are overpopulated, undereducated, and harming other species.
If we don’t reduce the population significantly then we won’t have a population at all.

The following submission statement was provided by /u/strangeattractors:
Greenland's glaciers are melting 100 times faster than previously calculated, according to a new model that takes into account the unique interaction between ice and water at the island’s fjords.
The new mathematical representation of glacial melt factors in the latest observations of how ice gets eaten away from the stark vertical faces at the ends of glaciers in GGreenland. Previously, scientists used models developed in Antarctica, where glacial tongues float on top of seawater — a very different arrangement.
"For years, people took the melt rate model for Antarctic floating glaciers and applied it to Greenland's vertical glacier fronts," lead author Kirstin Schulz, a research associate in the Oden Institute for Computational Engineering and Sciences at University of Texas at Austin, said in a statement. "But there is more and more evidence that the traditional approach produces too low melt rates at Greenland's vertical glacier fronts."

Ok, Thanos.
What is the "bright line" that defines overpopulation? Capitalism creates a false sense of overpopulation, when the real issue is that resources are not adequately distributed because it's not profitable.
If trillions of dollars weren't currently being used as a dragon's hoard we could easily live on this planet with enough for all and little impact on the environment.

Uhm... what? Climate change won't wipe out humanity, no matter how bad it gets, but hundreds of millions of people are at risk of suffering a lot from it, particularly in impoverished nations due to drought causing deadly heat waves, food, and water shortages etc. but according to you that is good because then we have reduced the population?
Overconsumption is the problem, not overpopulation. As long as unrestricted capitalism reigns supreme this won't end.

Yes, people in developing counties will have a hard time preparing, but it’s not like Florida is going to be able to build a wall around itself. Some places where the dollar-per-unit of costal protection might be able to afford it (thinking NYC), but other places even in the US will have a harder time practically in the day to day (hard to move ports and what are we going to do about New Orleans?) and looking to the future (mortgage/insurance nightmares.)

Yes that's normal because glaciers always tend yo oscillate. The problem is that the absolute amount of ice on glaciers is going down, even if some individual glaciers go up it doesn't make it for the loss.

Preventing unwanted pregnancies is a cost-effective and ethical way to reduce environmental destruction and minimize population growth, and 45% of pregnancies in the U.S. are unintended. Of those, 58% will result in birth. Comprehensive sex education would go a long way, too, and many states do not include it in their curricula, even though comprehensive sex education has strong bipartisan support among likely American voters. Many women at high risk of unintended pregnancy are unaware of long-acting reversible contraceptive options, and many men don't know how to use a condom properly, which does actually make a huge difference. Besides that, it could help to ensure everyone has access to effective contraception, so consider advocating policies that improve accessibility of long-acting reversible contraceptives and help get the word out that it is ethical to give young, single, childless women surgical sterilization if that is what they want.
As for the rest of the world, it would help to donate to girls' education. It might also (perhaps counter-intuitively) help to improve childhood mortality by, say, donating to the Against Malaria Foundation.
All that said, population is not the most significant cause of climate change -- it's the market failure. That's why the single most impactful climate mitigation policy is a price on carbon, and the most impact you as an individual can have is to volunteer to create the political will to get it passed.
And returning the revenue from a carbon tax as an equitable dividend would help a little bit with inequality, while creating jobs and growing the economy.
Taxing carbon is in each nation's own best interest, and the IPCC makes clear carbon pricing is necessary.
Policy changes absolutely dwarf the magnitude of the impact of having one less child.

“In August 2022, China faced a crippling heat wave that disrupted factories and threatened crop yields — the worst since 1961. Global manufacturers, including Volkswagen and Toyota, were among the companies that suspended operations because of power shortfalls. And some drought-stricken parts of the country are still engulfed by the scorching heat.”
Drought also left the Mississippi River so low near Memphis in the fall that barges couldn’t get through without additional dredging and upstream water releases. That snarled grain shipping during the critical harvest period. Colorado River officials discussed even tighter water use restrictions as water levels neared dangerously low levels in the major reservoirs.
In Europe, heat waves set record temperatures in Britain and other parts of the continent, leading to severe droughts, low river flow to the River Rhine threatened 30% of shipping, and wildfires in many parts of the continent.
This is affecting crops all over the world, and there is a threshold at which the Colorado river won’t have enough water to supply California, where most of America’s crops are grown, as well as other states:
So yea, it is happening in our lifetime.

You're probably thinking of Antarctica, but even there volcanic activity is having very little impact.
There are no active volcanoes in Greenland, and no underwater volcanoes for at least the past few million years.
There was a hot spot under Greenland, but that was millions of years ago (EDIT: there may in fact still be a hot spot that is cooling, regardless, a hot spot that's existed for millions of years can't explain why ice is melting now) and it has since moved to Iceland:

That plume has existed for millions of years. It's cooling.
In fact, that very research you cited even states that the heat from the plume is feeding the Iceland plume, which is why Iceland has over 100 volcanoes, and over a third of them are active volcanoes (have erupted in the part 50,000 years). Greenland has no active volcanoes at all.
Volcanic activity and heat plumes function over geological time scales. That plume under Greenland was hotter when the ice formed than it is today.

For those who don't know, scientific estimates - especially those that are high profile, such as, you know, predicting the demise of earth's climate and ecosystems - are conservative by nature. Scientists know complicated models are very difficult to predict accurately in terms of magnitude and timeline. So rather than predicting maximum severity outcome in the near future, they will predict minimum consequences by maximum year. What they predict will - in terms of climate - will be more severe at an earlier year.
In other words, it shouldn't surprise anyone that Greenland is melting faster than predicted. Everything is happening faster than predicted.

About 23 feet.
Quote: " For example, if the Greenland ice sheet were to completely melt and the meltwater were to completely flow into the ocean, then global sea level would rise by about seven meters (23 feet)"
A recent study has shown that the existing warming (if we stopped producing GHGs today) would result in about a foot of sea level rise, but that is only about 3% of the total ice mass in greenland.

It's going to be awesome when the Atlantic meridional overturning circulation collapses.
Humans are screwed lol.

I make weird websites for fun. One of the oldest that is still online is for The National Rifle Association Christian Bible Choir, most of which I wrote as a teenager in the late 90's:
http://choir.faithweb.com/turner_robertson.html
Anyway, ahead of Biden's election, I began collecting notes for a satirical "Cheney-Bush 2020" website -- and got derailed by the pandemic. I didn't have internet at home until I needed it for work (somewhat after the Lockdowns), and when I couldn't go out to get online, well, no new website...
The unrealized project was premised on the idea that after 12 years of amateur rule (between Obama and Trump), America needs a seasoned ruler like Dick Cheney.
Because Dick Cheney has more experience running the country than anybody else eligible for the office.
So then I started thinking about what kinds of talking points might go along with a Cheney-Bush platform, and the "drill, baby, drill" crowd suggested a theme: "Global Warming is Cool."
Among the favorable, pro-business aspects of progress in global warming was a year-round Northwest Passage...

I can’t believe this is the top comment. Really? How many people think climate estimates aren’t extremely conservative? As most studies are they’re done to limit risk. Wake up. Our science needs our willingness to understand it.

We’re just getting started will have that up to 1000 times faster before you know it. If there’s one thing we’re good at its destruction.

The friction of the melt water trickling down from glacial melt lakes causes heat and further melt too, this also has been noticed just recently.

Greenland was named that for a good reason. It was green in the past.

Where did I say or link anything that said that these are inconsequential? Do you know what nuance is?
Besides, effects are already hurting humanity.

No, silly.
Greenland was named by the Norse explorer Erik the Red in the 10th century. At the time, Erik had been exiled from Iceland and was seeking a new place to settle. He came across the island of Greenland, which was largely covered in ice and snow, and decided to name it Greenland in an attempt to attract settlers to the area. Despite the cold and inhospitable climate, Erik's marketing strategy worked and he was eventually able to establish a settlement on the island.
The name "Greenland" is somewhat of a misnomer, as the island is largely covered in ice and snow, and there is very little vegetation. However, the name likely reflects the fact that some parts of the island, particularly along the coast, are more green and fertile than others. The name "Greenland" may also have been chosen to distinguish the island from nearby Iceland, which has a more temperate climate and is more green and lush.

Two fold issue:
- extremely conservative
- cascading effects.
So... yes and no, somehow in the same box.
TLDR: we're frakked

So although I don't know the exact ways to on how this would work in every detail my point is that it's not impossible to survive and that any attempt at survival is doomed to fail even if only a small percentage of humanity was left.
Financial_Exercise88 t1_j1fmyjj wrote
All humanity relies on a precise balance between O2 and CO2 in ambient air. Hemoglobin binds CO2 100x more than O2; it only works as an O2 delivery system because there's a hyper-abundance of O2 (declining currently, FYI). Genetic engineering or O2 supplementation mechanisms require extensive supply chains that won't exist if only a few survive.
And if we (humanity) survive but we (you & I) don't then the former matters little.
rixtil41 t1_j1g8wnr wrote
But what about the future where genetic engineering requires less and does not rely on a large number of people? Unless you think humanity will die off before that becomes a reality.
Financial_Exercise88 t1_j1hd2ce wrote
Can AI come up with an alternative to Hb that we can genetically engineer babies to have before the imbalance ambient air is lethal? Probably. But no one is working on it. It will probably affect behavior & intelligence in imperceptible ways long before humans see it as an issue worth pursuing. And then we depend on animals... we're going to replace the whole ecosystem with genetically engineered variants that can thrive in higher CO2/lower O2 environment (are we going to also change our dependence on the Krebs cycle which needs O2) ? No, I don't believe that is realistic. Supply chains will be long gone, humanity too, before then. Or, we could just tax the f out of fossil fuels. No. Brainer.

Greenland's glaciers are melting 100 times faster than previously calculated, according to a new model that takes into account the unique interaction between ice and water at the island’s fjords.
The new mathematical representation of glacial melt factors in the latest observations of how ice gets eaten away from the stark vertical faces at the ends of glaciers in GGreenland. Previously, scientists used models developed in Antarctica, where glacial tongues float on top of seawater — a very different arrangement.
"For years, people took the melt rate model for Antarctic floating glaciers and applied it to Greenland's vertical glacier fronts," lead author Kirstin Schulz, a research associate in the Oden Institute for Computational Engineering and Sciences at University of Texas at Austin, said in a statement. "But there is more and more evidence that the traditional approach produces too low melt rates at Greenland's vertical glacier fronts."
