Sea Levels May Rise More Rapidly Due To Greenland Ice Melt
An anonymous reader quotes a report from The Guardian: Rising sea levels could become overwhelming sooner than previously believed, according to the authors of the most comprehensive study yet of the accelerating ice melt in Greenland. Run-off from this vast northern ice sheet -- currently the biggest single source of meltwater adding to the volume of the world's oceans -- is 50% higher than pre-industrial levels and increasing exponentially as a result of manmade global warming, says the paper, published in Nature on Wednesday. Almost all of the increase has occurred in the past two decades -- a jolt upwards after several centuries of relative stability. This suggests the ice sheet becomes more sensitive as temperatures go up.
The researchers used ice core data from three locations to build the first multi-century record of temperature, surface melt and run-off in Greenland. Going back 339 years, they found the first sign of meltwater increase began along with the industrial revolution in the mid-1800s. The trend remained within the natural variation until the 1990s, since when it has spiked far outside of the usual nine- to 13-year cycles.

Washington D.C. is very near sea-level, isn't it?

Anything about mankind ruining the environment has to be fake news, right?
What I'd like is to -- someday -- see all these deniers, excuse seekers, carbon lobbyists, oil burners before a court, accused of crimes against humanity.
And then, the likes of Trump, the Kochs, most of the political class, Bannon, all that ugly bunch doing services in those places in the world where damage is highest (I'm not for jails, mind you).
Once upon I time, I thought it was a legitimate concern. But they've Chicken Littled it way beyond anything I have patience for at this point. Every week or two, we get another 'report' speeding up the timeline to armageddon by 25-50% or adding another foot or two to predicted sea level rise. I can only take so much before I have no choice but to write this whole thing off as fear mongering. To what end, I don't know, but it's clearly obvious at this point that it is - nothing is this dire. Nothing.
Look, I don't want to hand our offspring a big shitburger after we're gone. I don't want them to hate us and look back on us with disgust. But there's no way things are as bad as they say. I would have given money, changed my lifestyle, my purchasing habits, whatever was required - and I did, for a time. But after years of constant escalation of rhetoric, I am done. I'm not going to waste any more of my time or effort on this. Things will be fine, we'll adapt, some people will have to move, some species will die out. But life will go on. At this point we've turned it into a bigger issue than climate change ever was. Adios.
With that much fresh water entering the north Atlantic, it could well shift the North Atlantic current and that could more drastically affect the climate of Europe and create some dramatic cooling there. That might, in the long run, be worse for Europe than the rising sea levels.
Fucking hell, slashdot, must every other article be about global warming or trump or full communism now???
FUCK OFF
Seriously? With all of the billions of dollars that have been poured into climate "research," that research never took into account what might happen to Greenland ice sheets if the temperature increased.. until now?
The lack of attention to detail is just another of many indicators that modern climate "research" is completely insincere and disinterested in actually finding the truth. It's all about foisting an agenda.
A whole extra inch over the next 500 years!
As the weight of millions of tonnes of ice cap is released there should also be an increase in seismic activity. The potential for earth quakes in areas that were fairly stable is there. Hopefully sudden radical upthrust does not occur the way it did on the west coast of North America after last ice age. The native populations of the West Coast all have flood stories related to an upthrust event that occurred very suddenly. We cannot know for certain what will occur as the ice caps are lost but we can make good guesses at what could occur. Either way displacing a huge portion of the earths ice at an accelerated rate due to our redistribution of carbon from where it is sequestered into the earths atmosphere is not something we may be able to deal with other than with a sudden decrease in our populations and the resultant decrease in our use of carbon based fuels.
Sea levels will rise, right after the next ice age, that was predicted in the 1970s. These climate predictions must be chronological, right?
Attack Greenland! Send the best the Queen has! Up with this we will not put!
I'm personally going to buy a boat just so I can sail it over Mar-a-Lago once this happens.
#MAGA
Dooms day is coming! Repent sinners!
Stop it Greenland!
May rise? Let me know when we ACTUALLY see some sea rise. Then we can talk about 75% taxers and regulations that basically make everyone a slave to the government, you know like in Europe.
And there we go again, since more than 20 years, they are telling us the sea levels are rising, and we are to blame. And bij 2013 half Europe would be under water, than they had to correct it, it became 2030, now it's like 2050. And in the last 20 years, the sea levels haven't risen any centimeter, and the Netherlands still has the same beaches as 30 years ago...
Banks are still loaning you money to pay off for 30 years, even thou half Europe would be under water by then...
But hey you are allowed to believe any horror fairy tales you desire to...
Tell the truth, at least occasionally.
I've been told the Himalayan glaciers will be gone by 2032, it was a misprint from an alarmist advertisement with no scientific backing, but was reprinted EVERYWHERE about 10 years ago.
It will never snow in DC again, then DC is crippled by snow that year.
It will never snow in UK again, then the UK is crippled by snow.
Its the warmest year in the US by FAR, until you include Alaska that year then it was one of the coldest ever.
Sea temps are going up faster than expected, first person who double checks it finds they lied (Just 2 weeks ago)
Polar bears going extinct, Canada is now having issues with Polar Bear overpopulation in areas.
It just never stops with the EASILY provable lies they tell. You can go ahead and say those are journalists, but none of you AWGers are calling out the lies and it made you lose credibility. You knew they were lies, and called people names for pointing it out, because the lies supported your agenda, not realizing it wrecked credibility. You've lost most people because of that.
If it stops the north atlantic conveyor, it could cause a mini-ice age instead, that would refreeze the arctic. Of course, northern Europe, Russia, nor anybody close to the equator might not be happy.
I prefer the "u" in honour as it seems to be missing these days.
So, I hear millions of people are going to die... Uhh... How? Are they just going to wade into water and drown themselves? Are they going to walk into deserts with no water? Are they going to sit in the sun, day after day, with no food or water? People that believe claims like this are complete idiots. And many do. Actually, we should be lucky, considering much of the Northern half of the USA is usually covered in thick sheets of ice. It's only because we're in a cycle as described by Milankovitch where, yes, the world is warming. But this is only temporary. As our irregular orbit around the sun continues, we'll eventually peak, and then quickly descend into another ice age. So really, enjoy the warming it while it lasts.
temperatures have been both warmer and cooler and within historical times.
Northern Europe being forced to stop a thousand years (from Roman times until the middle 13th century) of cultivating grapes should be enough for anyone. Any vineyards in Scotland today?
Too late. Trump is already here and is now running the deficit up to 666 Billion/year.
I wonder how much Obama added to the deficit? oh yeah, you don't care because you're an NPC liberal. You can only repeat, "Trump bad" and know nothing else.
For this reason, God sends them a powerful delusion(operation of wandering)(planet) so that they will believe the lie.
Working of Error
Actually, I'm GDI, and was registered Libertarian for over 25 years. O did not increase the deficit by much except with his tax cuts. ACA was fully paid for, unlike gop's Medicare part D. And his temp spending up front was to keep us out of depression. Trump's spending and tax cuts are pure disaster.
I prefer the "u" in honour as it seems to be missing these days.
Just asking...
5 out of 6 people enjoy Russian Roulette & 6 out of 7 Dwarfs are not Happy
Under President Obama, the national debt grew the most dollar-wise. He added $8.588 trillion. This 74 percent increase was the fifth-largest.

If all of Greenland's glaciers melted, sea level would rise ~ 6 meters (about 19.7 feet)
https://www2.usgs.gov/climate_landuse/glaciers/glaciers_sea_level.asp
Beginning about 15,000 years ago, continental glaciers retreated and sea level began to rise. Sea level reached its current height about 8,000 years ago and has fluctuated ever since.
https://www.usgs.gov/faqs/how-does-present-glacier-extent-and-sea-level-compare-extent-glaciers-and-global-sea-level
Global sea level has fluctuated widely in the recent geologic past. It stood 4-6 meters above the present during the last interglacial period, 125,000 years ago, but was 120 m lower at the peak of the last ice age, around 20,000 years ago.
https://www.giss.nasa.gov/research/briefs/gornitz_09/
Because of all of this, there were many books written in the 1960's predicting a new ice age (Global Cooling).
We need to keep the earth clean, yes. But the hype is stupid. As someone else stated, percentage changes mean nothing.
Right. So if you're a lefty liberal dem then those obama trillions of debt don't matter. Got it. But billions by orange haired man do matter because you say it does. So you are justifying your obama sweetheart and decry orange haired man for doing less harm and trying to correct the problems. Typical dem. How about you be true to your country instead of your party. Sure there's a long way to go but surely you can see how unsustainable and unrealistic Obamacare was (I'm guessing you're a blind dem so no you won't see it). Sorry but you can't have it both ways. Sure you want free lollipops and unicorns but at some point free healthcare has to be paid by someone and it's unrealistic. Socialism doesn't work and never will. It has failed everywhere it has been tried.
Remember that time that the climate scientists accurately predicted sea level rise? Me neither.
Denialists would often ask, "what if these imperfect estimates are too high?" and scientifically-minded people would counter with "what if these imperfect estimates are too low?" In the last few years it's been obvious that they were mostly too low (as in conservative) across the board. Oddly enough the constant unfounded accusations of bias toward climate science has created a real bias toward conservative estimates, as scientists all fear overestimating and becoming the deniosphere's celebrated Chicken Little.
"When information is power, privacy is freedom" - Jah-Wren Ryel
Whenever it's fucking cold and snowing outside, the number of "climate change" articles has to increase to remind me that global warming really is happening, trust us.
If ACA was paid for then why was it failing and everyone's premiums went way way up when they were promised by your sweetheart O was to go way way down?
Unlike you who can only say Heil Twitler?
Shrub's administration crashed the world economy by choosing not to pay attention to what was going on in the housing and banking markets. But you're like Honey Badger, you don't care.
You should be thanking Obama for saving the economy; if not for him, you'd probably be living under a freeway overpass. But sure, whine about spending what needed to be spent to reboot the economy after W's malfeasance.
And, BTW, please do tell us who controlled the House for six, and the Senate for two of Obama's eight years. Congress spends, not the President. Dumbass.
Ever wonder why? Have you forgotten the housing market collapse and the subsequent stock market crash? All thanks to banks making risky loans and buying toxic assets guaranteed by the gubmint. Shrub's gubmint. That wasn't paying one bit of attention to what was going on.
Maybe you could educate yourself. Just a little bit. It doesn't hurt much.
The whole notion of sea level rise assumes that the Earth's crust is static and unchanging. Definitely not the case.
Has anyone here read the article, or is it just "oooh...glaciology...no one can tell me anything about glaciology that I don't already know."
It all tribal politics all the time here on Slashdot?
More liberal bias from Slashdot.Org. I just looked outside and it is snowing, I guess its global cooling again, huh you chinks.
Since mankind looks to the skies watching lightening and fearing thunder humans have feared the end of the world is nigh. Through the ages this has not changed, yet people keep believing this nonsense. If it isn't the world freezing from nuclear winter, from starvation in the 1800's, and nuclear destruction blowing the world up people will be fearful of what they cannot control, and what they do not fully understand.
People. Get a life. You are a fool if you live your life listening to these fools. Read history and you will become enlightened. You will understand that this is just human nature to fear the end of the world. Henny Penny, Chicken Little have nothing over you these days. Busybodies with nothing else to do.
The question is, how much ice should those models assume will melt in response to a given degree of global warming?
When you read a popular press account that says "Sea level may rise 2m by 2100", what the scientific papers actually say is more like "sea level may rise between 1m and 3m under the RCP8.5 scenario." Nearly all of that uncertainty is driven by uncertainty in how rapidly Greenland and Antarctic ice will respond to rising temperatures. So you have to go have a look to see what's already been happening.
Scientists tend to avoid talking much about worst case scenarios, because as far as we know the worst case scenarios are, as far as we know, unlikely to happen. The worst case sea level rise is catastrophic to the global economy, and if you actually thought it was going to happen you'd move to high ground and be stockpiling food and weapons.

Does this same report indicate when Greenland will be underwater due to the ice sheet that had formed on top of it thawing out? My prediction: it will never be underwater in our lifetime, or the lifetime of anyone born in the next million years. The reality is that H2O has 3 states, it leaving one state does not mean it is only going to change into one of the other two.
To anti-Trump pro libtard climate crazy bullshitness.
It should be noted that we are not "killing the planet". The planet has gone through 'tougher' things than us puny human ants.
What we are killing is ourselves by eliminating the relatively comfortable conditions that we have lived in the the past few thousands of years.
Further, our civilization was bootstrapped to the cheap and easy sources of energy of fossil fuels. There was a one-time supply of them never to be available again (at least not for a few million years).
It is prudent to keep some around in case there's a global Dark Age collapse (e.g., new plague) and we have to re-bootstrap things. Better to use renewables where possible and keep the non-replaceable stuff around for possible future use.
Enjoy being poor Chinesr slaves under water Amerikuks!!
You should really read up on Operation Mockingbird and MK Ultra so you can find out how you've been mind controlled.
check out the fake science data IPCC hockey stick graph while you're at it - then as the IPCC, pretend you have any scientific validity anymore lolololol
Nope, Obama's discretionary spending was under 1/5 of W Bush. You're just a dishonest faggot who doesn't understand debt in linear time goes up either way, and can't admit who actually spent the money on what.
Go figure, you live in faggot Tulsa.
You know that Florida is mostly low-lying and already suffering as a result of sea-level rise? Well, it now looks like you can look forward to hoards of Floridian climate refugees seeking shelter across the USA sooner than you expected. You know Florida? Where the bat-shit crazy people tend to be? They'll soon be among you. May you live in "interesting" times.
Debate is a form of harassment. Do not question my truth.
The debt grew, but, he was handed a 1T deficit, and brought it down. Had the deficit level remained where W/GOP left it, things would have been far far worse.
I prefer the "u" in honour as it seems to be missing these days.
Here's a good way to think about climate change:
Earth has a greenhouse effect and carbon dioxide is a greenhouse gas. If carbon dioxide increases, then, all things being equal, there will be a greater greenhouse effect.
Now, climate science is notoriously complex and the atmosphere interacts with the biosphere, so the "all things being equal" part is self-evidently nonsense. So maybe there will be some feedback loop or whatever and carbon dioxide can increase without affecting climate. But the burden of proof is on the person advancing that hypothesis, because the default assumption is that warming will occur.
Start with that, and rational discussion can take place.
...Perhaps even worse, at least for us, is that it's looking like such transitions don't happen smoothly. As the thermal engines driving weather destabilize, weather patterns become less predictable from year to year, and the rate of crop failure increases considerably as a result. And when people get hungry, wars break out.
Sounds like a testable hypothesis. In the last century global temp has risen around 1C after having remained comparatively stable prior to that. One could take global crop yields, and compare the annual trends against the change in global temperature.
The trouble is, that your hypothesis of increased crop failure, and presumably decreased global yields(else if yields don't drop who cares), presupposes that all other things remain equal...
Of course, global crop production has been trending persistently upwards as temperatures have also trended up. Numerous advances in crop technologies and techniques being a portion, and additionally regions impacted by climate change where conditions become too warm/cold/dry/wet for one crop are rotated for others. Farmers don't stubbornly plant the same crop for decades when conditions change, even if that would make projecting trends easier...
"Global warming deniers" and "highly intelligent people" are mutually exclusive categories.
Oh wait, maybe there's a tiny intersection in the venn diagram, where they overlap with the "selfish machiavellian lying assholes" category. They say they deny it, but only to further their selfish ends of not having to make any lifestyle or policy changes. If they are intelligent, they know their denial stance is just posturing for effect.
Where are we going and why are we in a handbasket?
Please cite for us exactly what sea level rise has done in Florida in the last 100 years. Exactly how many people have had to move from where to where? Exactly what mitigation has had to take place? And why has there been exactly NO mitigation from sea level rise where I have been visiting the exact same spot in my state for the last 56 years? Not one person has had to do jack shit because of sea level rise here. You think you know what is happening, but reality is a bitch baby.
What problem was he trying to correct? Rich weren't getting rich enough fast enough?
Deficit not rising fast enough?
Are you tired of winning yet?
