If Greenland's Ice Melts, Sea Levels Rise 23 Feet | Video

- "And it's melting!" according to NASA. The deep ocean beneath Greenland is fueled by currents from the subtropics. This warm and salty water is melting the ice from the bottom up and much faster than the surface water. A new NASA project named Ocean Melting Glaciers (OMG) will be gathering more data on the ice melt over the next 5 years.

If Antarctica or Greenland melts, what SLR will there be? For Antarctica, if it melts, SLR is estimated at 206 ft (62789 mm). So
over 5000 yrs, this is 12.6 mm per yr. If Greenland melts, SLR is estimated to be approx 24 ft (7300 mm), over 5000 yrs this is 1.46 mm/yr. So, for both to melt, 12.55 mm plus 1.46 mm equals 14.01 mm SLR for 5000 yrs. You must have a corresponding decrease in Earth's rotation also. So, at the present rate of approx 3 mm SLR, it will take 23,333 yrs if the melt is linear.
The alarmists have been yelling that the sky is falling for ever.
No, they've been yelling: _"The sky is falling, now give me more of your wealth and freedom or we'll shoot you."_
10,000 years ago a gigantic melting glacier sat on the very spot I now call home.
Did cavemen driving SUV's melt the glacier or did extraterrestrials steal it from the Earth?
Why didn't this massive glacier drown the entire North American continent if it melted?
All lies
@@mizer9510 Great Lakes. Is that a lie too?
@@europaeuropa3673 Yep
My geography teacher says that in 12yrs so much of Greenland will be in the water that most countries will disappear under water
If the sky falls the pieces which fall into the ocean will cause the sea level to rise. Chicken Little ran around crying 'the sky is falling' but people laughed. Just wait. That sky could fall any day.
That movie is fake
Greetings from 2019.
Yep.
Definitely.
We're f***ed.
AL Gore approves this message.
So, again why not recut all the inland waterways to accommodate for some water displacement? Excavated earth would help raise lower lying areas.
3:00 why is there an half sun, there isn't even a cloud blocking it
It’s happening
So if the sea level rises what would happen to places around the world like miami or new york or italy?
+TrollinErryday155 those cities would get flooded, not just those, a lot of cities and countries.
+ChrisTobi They will join some ancient cities and settlements which are now under water, some 100 feet under water. Btw, 1000 years ago the Vikings had farming settlements on Greenland which means back then it was warmer than it is today.
+Philip Br Say that to London. There's dams on the Tames and it was a huge undertaking to make it work.
You can't just build a dam around and not have traffic. "The spice must flow".
+ChrisTobi I'm sure if they know it's confirmed to happen they will jsut make higher walls or barricades
im scared that days of trials..
I've been hearing about rising sea levels for 40 years. High tide looks about the same. What should I deduce from these two apparently contradictory observations?
That you're very shortsighted.
It takes TIME. Mountains don't
rise in a few cenuries.
Ice ages develop and fade over
hundreds of thousands of
years.
You have to take the
loooong view.
However...
It does seem to be accelerating
and the heat wave in Greenland
and Siberia burning to a crisp
(all that permafrost!)
may be signs that it indeed
is accelerating exponentially.
Which means rapid sea level
rise and totally ridiculous
changes in weather patterns
that outrun any paltry steps
we take.
And since our Idiot in Chief
has eviscerated environmental
protections and put former
oil and gas lobbyists in charge
of the EPA and others, the
wolves are guarding the henhouse.
We're f***ed.
Climate change is a myth. There is always going to be higher temps and lower temps and extreme weather. That is just the way the Earth works. We are in no more danger of climate change than at any other time in history.
the added weight of glacial meltwater has pushed the seafloor down resulting in shorelines receding how does the sea floor fit into your numbers?
You're delusional
It's a big if.
This was 2015 -- has The donald tump defunded this also?
How would the fresher water being put into the northern Atlantic affect the ocean currents?
It wouldn't
Murphy's Law?
amazing
well Greenland is now refreezing. record cold july temp -33c. so sea level rise now slowing .we head into a solar grand minimum.we will cool even faster
It ok we'll just build another noahs ark, i mean how hard can i be to build a ridiculously unrealistic sized boat and collect samples of every creature on the planet so they can all interbreed when the water subsides, easy.
+H4WK69
Don't forget to build a cryogenic lab, that contains the samples of all viruses and bacteria. Of course Noah had that, including a power generator, to keep the lab working.
Andy Spark Absolutely but lets leave aids and flesh eating bacteria behind this time eh.
H4WK69 agree
dios porfavor perdonalos no saben lo que estan ablando...

This is fake there is no ice
