In the future, seas will rise far higher than they are today. The question is whether it happens quickly or slowly.
There's enough ice stacked on top of Antarctica to raise seas around the globe by almost 200 feet. While it takes time for major changes to occur with that much ice, Antarctica is melting faster than we thought, according to a study recently published in the journal Nature.
The melting rate has been speeding up significantly in recent years.
Between 1992 and 2017, Antarctica lost more than 3.3 trillion tons of ice, causing sea levels around the globe to rise an average of 8 millimeters. About 40% of that loss occurred between 2012 and 2017, according to the new study. From 1992 to 2012, the continent lost about 84 billion tons of ice a year, and over the next five years, that jumped to more than 240 billion tons per year.
If the acceleration of ice melt were to continue, it could potentially cascade, leading to runaway ice melt and rapid sea level rise.
The biggest changes have come in West Antarctica, where the glaciers holding back ice sheets rest on rapidly warming ocean waters, causing them to melt more quickly.
Climate science professor Chis Rapley of the University College London has previously described Antarctica as a "slumbering giant" of ice melt and sea level rise that seems to be awakening.
"This paper suggests it is stretching its limbs," he told the UK Science Media Center.

SURF’S UP!
Enjoy.
I used to have some fake $20..00 Al Gore Carbon-Credit dollars. I would be discussing global warming with liberals and I would offer to explain the science and meaning of global warming to them.
If they agreed, I would ask them for $20.00. After they gave it to me as part of this demonstration, I would give them an Al Gore Carbon Credit.
I would then say, do you now understand global warming? They would generally say, NO. I would then explain:
You have a Carbon Credit, you feel better about yourself.
Al Gore has your $20.00, he feels better about himself.
I am out nothing and I know I feel good.
That’s about the only target in the range we’d be a little upset about. More than one romantic rendezvous has been had there!

West Antarctica's ice sheet is mostly submerged, meaning, as it melts, sealevel actually declines (ice floats). But I'm sure the insurance claims for the sudden 8 millimeter rise must be devastating, or rather, would be were the claims actually true. Thanks EdnaMode.
Political science, that is science driven by politics.
Is this net or absolute ice lost, all the studies I have seen say it is growing not shrinking.
If the ice melt in increasing but new ice creation is increasing even faster, does it matter?
Invest in property at or above the 200 foot above sea level. It will be water front property at some time in the future./s
I ask the same question of liberals in the Florida Keys. The answer they’re programmed to reply with is always “there is still time to change things.”. You can’t win with these deadbeats.
WHY is NYC still here ?
Not only that, but while it all the ice in Antarctica were to melt it would cause sea-levels to rise the 200 feet - even if the worst of the warming predictions were true, it would’t Melt the vast majority of either Antarctic or Greenland ice.
Utter bullsh*t from start to finish.
Odd. East Antarctica ice cap (More than 80% of the ice cap down there)has been gaining ice mass. As had the Antarctic sea ice, steadily growing between 1992 and 2015.
“Oh no!!!!! We must do something!! But what exactly??!!!”
Drink faster!!!
Or let’s dig the bottom of the oceans deeper!!!
sorry ideologically motivated leftist academics have been proven as severely faulty as any authority on this subject.
Barricade the doors! Nail boards at irregular angles across the windows! Panic and run around in circles screaming “We’re DOOMED!!!””
Quick call Bicycle Repair Man!
Somebody better tell Al Gore to start rolling up the carpets and moving furniture to higher ground at his seaside mansion in California.
WE live in a sailboat in the ICW of coastal Georgia. Higher water means more places we can go.
The sky is falling, the sky is falling, where will we go when the sky and ocean merge and we have no land. OMG, OMG, OMG!!!
