How long before all the ice melts? - BBC World Service
Ғылым және технология
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.

I believe that although there are visuals for this post the poster is BBC WORLD SERVICE which is a radio channel. I watched the vid titled "is it too late to save the Greenland Ice Sheet" which is the visuals to this.
I notice that the ice looks dirty which absorbs more heat from sunlight and further increases the melt.

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.

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?

Theirs studies that earth interior has 3 times the water trapped in rocks in our planet interior that what sits on the surface.

You're confusing glacial periods (ice ages) and interglacial periods (like the climate of the dinosaurs) which last 10's to 100's of millions of years, with glacial maximums and glacial minimums that last 10's to 100's of thousands of years. The last glacial period began 55+mya and the earth is currently still in the middle of that glacial period. We are at the end of a glacial minimum that began 12+tya and should be slowly cooling as we head towards the next glacial maximum, instead of rapidly warming Search: Melankovich Cycles. Enjoy.
With the accelerated warming and melting I don't see it taking millennia to melt. What really worries me is that the glaciers will break lose and slide off into the ocean en mass. If that happens, not only will it immediately raise sea levels dramatically but it will create a tsunami like we have never seen in our lifetimes. I hope you are right and we do have hundreds/thousands of years. I just don't see it from the studies I have seen.

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.”

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.

Arctic Sea Ice melting only makes a very very small contribution to SLR (and only because of salinity difference). What will be very significant is when we run out of sea ice up there and the heat has to go somewhere else.

Smaller objects have more surface area to mass plus the lowering of the glacier's altitude will obviously bring it into warmer air.

I am 74 and having my health problems but at the rate of Arctic ice loss I may see the Arctic Ocean ice free. We are talking about the Arctic Ocean not the land. Each year there is less ice to melt and more heat available to melt it, so each year a greater percentage of the Arctic Ocean ice is lost, an accelerating cycle.

Perhaps BBC world service is not the BBC. And if they showed the video portion they would get a copyright strike. I cant see why else they would bother to put a audio recording on You tube.
I think I would prefer a still photo of ice or something, maybe a map. The weird waves are making me think the video is broken.

Same. Watching this kind of video (radio) I just put this on my counter while cooking or brushing my teeth and listen to it. It is quite annoying when you wanna see what is the scene or footage instead of seeing a video but it is really just a radio.
This is great and informative program, but what has happened with video?
Where is the picture???? Wtf?!
When will it melt ??? Don't know nobody kept records the last time it happened. Nobody knows the speed or ins and outs of the warming cycle.
How long before all the world is covered in ice .....

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?
Sorry to say this, but your graphic between pictures and clips it is anoying and I gust skiped after 5 mins to where are pictures and clips,
Why take camera's to record the helicopter landing on the ice and then turn them off after 5 seconds? *A picture paints a thousand words, moving pictures even more so.*

Yes it will. The UK is, in some parts, still rising from the last Ice Age.
Anyone notice that most scientists say it will be 1000 years. Eco anxiety destroys young peoples lives. Still looking for that sea with a slope. Want to go water skiing.
Why upgrading Infrastructure and related technologies, matters. Besides, we need the practice for developing underwater Cities.
Nice topic, but please show more of the interviews and other video. The graphic is ok, but very annoying.

Ice has been melting for about 18,000 years.
We're about 2.6 million years into the Quaternary Ice Age, which might last 100 million years. We are in the 45th interglacial (a brief, slightly warmer) period. The cold will return. But even this warm spell today is not far from the coldest range Earth has ever been. Nevertheless, ignore the geological record, adopt an emotionally-potent oversimplification, and blame donaldtrumpdioxide. Thanks BBC.

So far this year there’s been record ice gain ,and it’s only end off October
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.
All the ice will never melt.
Greenland is a contributer to sea level rise. The floating Arctic ice cap is more critical. The ice cap keeps the Arctic Ocean cold. Once the ice cap is gone the ocean will warm releasing CH4 and CO2 from the methane hydrates and permafrost. Melting Greenland ice and Antarctic ice faster.

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.

@@Nathan-ry3yu Yes true, floating is as in the Arctic will not raise sea level. But once the ice is gone the Arctic Ocean will warm rapidly releasing lots of methane and carbon dioxide accelerating warming. Continental ice like Greenland (3 km thick sitting on rock) and Antarctica will raise sea level tens of metres.

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

It's not just algae. As the ice melts back ash from volcanoes, forest fires and even meteoric material, matter that obviously doesn't melt, accumulates into a single layer which darkens the surface thus helping the ice column to absorb more of the Sun's heat. It is a runaway process that can only be stopped by very cold temperatures which can only happen if we swab the atmosphere of its added human-produced greenhouse gases.

There is nothing going on with the climate to be concerned about or whatever nonsense scientists can cook up to get funding. Worry about real things like reducing the power of the governments which are currently ruining our prosperity and causing death and destruction from viruses and wars.
