How long before all the ice melts? - BBC World Service

We know the Earth's atmosphere is warming and it's thanks to us and our taste for fossil fuels. But how quickly is this melting the ice sheets, ice caps, and glaciers that remain on our planet? That's what listener David wants to know.

With the help of a team of climate scientists in Greenland, Marnie Chesterton goes to find the answer, in an icy landscape that's ground zero in the story of thawing. She discovers how Greenland’s ice sheet is sliding faster off land, and sees that the tiniest of creatures are darkening the ice surface and accelerating its melt.
CrowdScience explores what we're in store for when it comes to melting ice. In the lead-up to yet another UN climate conference, we unpack what is contributing to sea level rise - from ice sheets in Greenland and Antarctica, to melting mountain glaciers and warming oceans. There's a lot of ice at the poles. The question is: how much of it will still be there in the future?
Research Professor and climate scientist Jason Box from the Geological Survey of Denmark and Greenland shows us how much ice Greenland we've already committed ourselves to losing, even if we stopped burning all fossil fuels today. His team, including Jakob Jakobsen, show us how these scientists collect all this data that helps feed climate models and helps us all to understand how quickly the seas might rise.
Professor Martyn Trantor from Aarhus University helps us understand why a darkening Greenland ice sheet would only add to the problem of melting. And climate scientist Ruth Mottram from the Danish Meteorological Institute breaks down how the ice is breaking down in Antarctica and other glaciers around the world.

[@davidmchugh-hypnotherapist7213]

I notice that the ice looks dirty which absorbs more heat from sunlight and further increases the melt.

[@EmeraldView]

Because as it melts the few particles of dust at each new level accumulates more and more at the top. Yes this heats faster and creates a positive feedback loop. 😕

when i saw that ice, ..it looked "water laden" to me, .. very wet, loaded with water, slush maybe depending on the temp.

[@maryjeanjones7569]

This is usually caused from the ash from forest fires. Ash travels far and wide and can land on ice which in turns heats up the ice because the sun does not deflect. In turn causes the ice to melt faster.

The snow and ice on the Greenland Ice sheet has been melting forever that is why it is not reaching the sky. This show is scaremongering for the oceans to rise a meter water would have to be stored on all the land mass to the height of two meters, this is due to the land covering about half the area of the oceans. Imagine Australia would have to hold two meters of water over its entire area, this would need to be repeated on all the continents for the sea to rise a meter.

[@George-ed5wj]

So let me get this straight? You as a reporter flew out to talk to scientists which you could have done via the internet and actually provided more footage than you did! Then jumped on a helicopter ride only to capture a few minutes of footage of ice melting, which you could have easily obtained from tons of stock footage!

Are there any concerns about trapped organisms being released and causing us potential harm? Thank you for uploading and sharing.

[@Timlagor]

Some carbon emissions are worthwhile. Ice weight loss does have an effect on volcanic activity but it's not the biggest concern. There are concerns about trapped diseases (and some very old organisms have been reanimated) but the risk is mostly considered very low (they'd probably be very vulnerable to antibiotics if they even got going at all -those reanimations happened in lab conditions).

[@Ominousheat]

Oh, so you think sea level rise won't harm us? JFC! Wake up cuz. Every major city on a coastline will be permanently flooded within the next 50 years. 200+ nuclear power stations are on tidal waterways. Imagine Fukushima x 200 and without any way to clean it up or hold back the radioactive material. So probably Fukushima X god knows what. No life on the planet would get away from that. And that will happen just with the loss of Antarctica's Thwaites glacier. As far as disease is concerned probably the worst thing that can come out of the frozen ground is Anthrax. However, the Greenland ice shelf does not have any dead animals inside it. Except maybe at its grounded point. But if the melt gets down to there a disease will be the last thing on our minds as we try to evolve gills in water-world.

The last glacial period began 55+mya and the earth is currently still in the middle of that glacial period.

My 'puter exploded and then melted into a steaming pile of bubbling plastic when I tried to do it! We burned 8,000,000,000 TONS of coal in 2021, and we mindlessly and so often needlessly burn 100,000,000 BARRELS of oil DAILY, driving 23 ZJ into the oceans every year. Remember, you do the math, my 'puter is toast. We are accelerating our drive to extinction much, much faster than any of the MSM (yes, even my dear BBC) has told us, otherwise we'd be eliminating ALL unnecessary travel by any fossil fuel burning conveyance, and using CONTRACEPTION to prevent the horror that awaits the next generation and after, if there is an "after".

Why can,t they tell the world the real reason why the ice is melting in Greenland and the Antarctica this all started back in 1995 .when the poles shifted position the earth tilted changing the core of the earth to put more pressure on the mantle which over the past 30 years has become thinner in certain parts of the earth the core of the earth is spinning faster than usual that's the reason there have been so many volcanic eruptions and earthquakes .the earth has grown larger and is releasing it's pressure.there are 140 active volcanoes on the west coast of the Antarctica .and there are big lakes under Greenland heated by the thin mantle.and how many other undersea volcanos are there.climate change has nothing to do with humans or cows.the cause of the problem is from within it,s just one big coverup.best wishes and greetings from iceland.

@@DrSmooth2000 If Thwaites collapses that is a 7m rise defo before the end of the century. And highly likely at least 6 feet before mid-century. 2m is a massive game changer and will exacerbate the melting of all other ice stores. Greenland, as it shrinks, will increase it's rate of melting due to the physics. Smaller objects have more surface area to mass plus the lowering of the glacier's altitude will obviously bring it into warmer air. Add the increase in global temps heating the oceans and I can not see how we can avoid 14 to 20 meters SLR by the end of the century without beginning to scrub the atmosphere of CO2 now. That is a calamity for civilisation and the ELE we should avoid. I fear for large ocean-bound mammals. We may lose the likes of Whales forever. It's all looking pretty grim.

Thanks for the report. One problem I have never seen mentioned is that there is no need to melt the ice to rise the sea level, it suffices that glaciers calve into the ocean. It will do the job just fine. The melting can take than whenever it does. Am I mistaken? How "good" are the chances that a huge amount of ice gets calved into the sea, let's say 1/7th of the Greenland ice shield, in "on go" just because there is enough ice molten to make parts of the shield swim enough to glide enough for the slope it is on?

[@Nathan-ry3yu]

I did a model I put sand in bucket and water around it. Than I added ice that raised the water level. When the ice melt the water volume leval stayed the same. So to say the sea will rise is a lie.

[@thiemokellner1893]

@@Nathan-ry3yu Your model is incomplete. If adding the ice made raise the level of your water, it is a model for the ice swimming in the Arctic sea. You might add a mighty block of ice on top of your sand on a stone that does not touch the water. Mighty only to see the melting effect on the water level more easily. The adaptation reflects the glacier ice in high mountain, the ice on Greenland and on the Antarctic continent. Or if you want it simpler, place a cube of ice in a glas that gets smaller to its base, e.g. coca-cola, such that it does not touch the ground the cube has to be big enough. After the ice has molten, you can tell us whether the level of water in the glas has risen.

The calving only occurs when there is sufficient ice for the whole length of the glacier to have flowed to the sea. So the total ice captured in the glacier has not changed.

New data shows Antarctica if it melts only about 2% sea leval may rise but no evidence to state it will happen either based on new discoveries of sea water leaking between our tectonic plates in the sea and getting trapped in rocks deep within our interior planet.

[@spraudoggy]

From NASA…”The question: Melt ice cubes in a glass of water, and the water level will not change. Can the same be said for ice floating in the ocean? The answer: There is a common misconception that sea level change comes only from ice attached to land, and not from floating sea ice. Although that is mostly true, it turns out that there is an effect, even if it is minor. An often-overlooked ingredient makes a significant difference: saltiness. Various studies show that because floating ice is made of fresh water, it actually increases sea level slightly when it melts into the salty sea - unlike what happens in your water glass. A floating object, like an iceberg or other sea ice, displaces its own weight in water. But fresh water is less dense than salt water. So, when floating ice melts and becomes liquid, it takes up more volume than the seawater it displaced when it was ice, raising sea level. This has about 3% the effect of grounded ice-melt and raises sea level.”

Poor editing. You rely on that wavey graphic too much. I have lost interest in your little Story time blurb, about what, again?

[@Talksin403]

14,000 years ago the ic sheet was 2 miles deep covering north american Let melt ,.

[@harperwelch5147]

Seriously? BBC is going to post the answer to how long before “all the ice melts”? There is universally agreed information to support an answer to this?

[@phil20_20]

How about, Penguins? It's important to stop looking at this as Greenland Ice Sheet problem and start talking about the Big Kahuna downstairs, because Greenland is tiny by comparison. The two figures of sea level rise are getting conflated, much to the detriment of those advocating action over theories.

[@Buckshot99]

Ice has been melting for about 18,000 years.

[@certiPHIer]

Could they make White inflatable pillows to anchor over the algae blooms to kill them off and keep the ice from melting so fast?

[@thiemokellner1893]

How much CO2 would we need to emit to produce and install those pillows? What do we do with those innumerable pillows once we do not need them anymore? Let them float the oceans to create the next disaster? We are not even capable of handling our day-to-day waste properly.

[@JamesPilkenton-se5cx]

Love your work. Pardon please but does the plethora of internal combustion engine contribute to the melting factor ? Not just automobile but all of it. Lawn equipment,trains, construction equipment, aircraft,boats and shopping ? Can a person effectively make a difference beyond give up the personal ride ?

The BBC sent a crew to such a remote location for such an important topic and didn’t take camera and sound.. this is a terrible video only suitable for a podcast.. very disappointing

[@saschaesken5524]

Look at the dark dust on the ice. Thats the reason why ice melts much faster when the sun shines on it.

[@Peoples_Republic_of_Cotati]

Current Doubling Rates suggest a much faster rise in sea level during the 2100s...but that should be avoidable I guess. But if not, then all ice melted by 2200's is my guess.

[@Philip-x3d]

might be a little while longer yet, but dont worry. Earth has spent more time WITHOUT ice caps, than it has with them. Dont think the world has always been the way it was when YOU were born and so should stay that way. And yes, we did have a period called "Snowball Earth" when ice covered 99% of the planet some 3 billion years ago and yet LIFE STILL SURVIVED.

[@cat793cdumpy]

It is minus 80 degrees in places on this planet and that will never melt.

[@mysticody]

would be nice to see what's going on. a lot of audible not a lots of video

[@mikeohawk95]

Due to the sci ne also of freezing in the freezer and icicles making, we could use techniques to rebuild the lost glacier of Iceland and use ln2 and advanced freezing techniques to refrozen mass amounts of our world water, take form the ocean,freezer and place in ice caps of the planet

When the waters finally unleash their full fury, not many will be around afterwards. The sea level will rise by a mile and after that, none of this will matter at all. We are due for another cataclysm. Nothing you can do will stop it.

"The models say it will take thousands of years for it all to melt but we can see that our models are wrong." Yeah I wouldn't be assuming it's going to take thousands of years. It would be nice if it does, but carbon dioxide is still accelerating, the capacity of the oceans to continue absorbing most of the excess carbon dioxide and most of the extra heat is very questionable, and numerous systems are committed to their respective tipping points. Don't buy land near nominal sea level, folks. Not unless you fancy being a kelp farmer.
