How the 'Doomsday Glacier' Could Change the World

- The Thwaites Glacier, an ice formation the size of Florida, can change the world. And the latest research shows that some of its most vulnerable spots are in greater danger than previously thought.
Thwaites holds a colossal amount of ice, enough to gradually raise sea levels by over two feet(Opens in a new tab)(Opens in a new tab), though its collapse in a heating climate could unleash many more feet from neighboring glaciers. The Antarctic glacier has destabilized, retreating back nearly nine miles since the 1990s. If much of it progressively melts in the coming decades and centuries, large swathes of coastal cities and populated areas around the globe could become submerged, and easily thrashed by storms. For this reason, scientists are now intensely researching where Thwaites is melting, and how fast it might melt. These are monumental questions for Earth's future denizens.

...and some people called me, a doomsday idiot... well, bite me.
Excellent video. Great content, cadence, citations and graphics. Thank you! Subscribed.
Oil isn't going anywhere. Too many rich folks want to stay rich. Adios.
lets build a freezer the size of florida that is powered by solar panels
You're joking, right? Freezers produce heat.
@@newwaveinfantry8362 the fact that you had to ask says a lot more about you than it does about me.
@@BrickTamlandOfficial It's a testament to how dumb YT comments tend to be. I've seen even worse.
Within the next 10 years, if we don't make drastic changes, we are going to have to update our model to include an additional 10 years before humanity is doomed.
You seem to misunderstand the meaning of prevention. You want the worst effects to happen before you’re willing to make the necessary changes to avoid the worst happening? That is a convenient way to allow the wealthiest to enjoy themselves while they destabilize life on earth for everyone else. Yea maybe another 10 years of compounding the effects of cooking ourselves alive would be helpful.
We all need to stop breathing, and reduce CO2.
Simples!😆💀
The melting point of ice is lowered about a degree C per km depth. When the slightly warmer salty water flows down the retrograde slope and hits the grounding line, it melts ice there. But the, now lighter water, flow up along the ice ceiling. It is slightly super cooled with respect to the melting point of ice at a shallower depth so it is not surprising that it doesn't melt this ice at a shallower depth. In fact, as it rises up the ice slope it freezes. The ice is in the form of thin plates called platelates. This is essentially an ice pump. Ice is melted at the grounding line and shifted seaward and into shallower water. It forms a slushy layer under the ice shelf. Each summer, most of this ice floats off into the ocean and is lost to Antartica.
Interesting but you need to clarify that you mean the "retrograde slope" of the shelf underside and not the sea bed. Not sure why you refer to that as "retrograde slope" but whatever.
'We were worried about the glacier breaking, so we drilled a bunch of holes in it.'
But if you lay more taxs it will help
Haha it's the size of Florida.
@@SandyChase that's probably why the thought of it breaking is so worrying
Please say the measures in centimeters also. Thanks
5:46 is that the expected 1.5 - 2.5 feet sea level rise?
the one in the vid has gotta be like 50 feet lmfao
Ice floating on water makes no difference to sea level when melting.
@@arnehofoss9109 It's a glacier. Most of it is ice on top of land.
Over long periods the climate ebbs and flows. They keep having to revise their thaw dates because glaciers haven’t gone anywhere.
Our weather is controlled by the Sun. Always has been, always will be.
That floating ice has had all the effect on sea levels that it can, melting makes zero difference.
At last, one intelligent person!!! Thank you!
That's true for floating ice but Thwaites Glacier isn't floating, so that's correct but entirely irrelevant.
That ice shelf is the size of Florida and 3/4 of a mile thick. Melting will add to sea level rise and it frees up the glacier behind it to move towards the sea. And everything I've read suggests that when the entire glacier is finally in the ocean, it will add 2 feet to ocean levels. Doesn't sound like zero difference to the people who will be alive in 500 years+.
@@ddhqj2023its not melting😅
This guys eyebrows will save us. Trusttt
Getting rid of oil won't save us. Too many ppl.
Yeah! Depopulation is what the real agenda is. Melting icebergs will cause rise in sea levels! Pah!
The Sixth Great Extinction is not a question of but when... Its all perfectly natural...
I think I got an apocalypse bingo
Just help that glacier melt speedly
I'm doing a video about your video, it will be ready in less than 20-minutes, so check-it-out in decades or centuries from now, you know, when you start caring about future generations! Professor-Marty.
What is the ulterior motive of the UN who were once promoting Global Warming in 2008 and now in 2024 Climate Change ?
To stop people from dying or being displaced.
One year later...nope, no change yet experts.
😂 I’ll be growing oranges in Alaska.

Put ice in a glass of water, when it melts, what happens?
Except Thwaites isn't floating in the ocean yet and it's likely to add 2 feet to sea levels. That would be the end of communities like PEI and Richmond and Squamish, BC plus Bangladesh which is currently at sea level not to mention some of the smaller island nations.
It's a glacier. Almost all of it is sitting on land.
1/8" of sea level rise per year means 96 years to get a 1' rise. Sounds bad ubtil you remember by then the ocean will just be rinsing away the remains of a nuclear holocaust to set up for the next iteration of humanity. We are currently living in Atlantis.
So we die. Meh
If??? Has the potential?? C’mon
DOOOOM !! DOOOOOOOOM, I SAY!!!
University of Amazon Peru Latin America city iquitos study Antártica oil prossesing since 150 years ago and Industrial revolution it has been since 262 years ago around the world wide
Yes we’re doomed .
bunch of lies
1:15 we are definitely doomed if we continue under capitalism.
Maybe they should stop driling holes in the ice.
you honestly think drilling for samples has an actual impact? wow.
Lol
Stop drilling holes in it and it will be fine
No your not scaring me into buying an EV. This is bullshit
As long as we have crypto I'm voting against fighting climate change.
when you speak in inches, feet and alike, you must also say the equivalent in centimeters, meters, kgs etc, it is basically in any scientific writing and speech as well as just a podcast. what cost you to do this? nothing But what cost you not saying both means of measurement... lots of misunderstanding or lack of understanding. See if you learn for the next podcast. It is Communication 101
Boo hoo
