One of the world’s largest and oldest icebergs is on the move after being grounded for over three decades, symbolizing how massive Antarctica is along with its profound relationship to the planet’s climate and oceans.
What’s happening?
Scientists are watching closely as the massive, over 1,000-foot-tall iceberg known as A23a makes its way toward the open and warmer waters of the Southern Atlantic Ocean, moving around three miles each day.
The iceberg calved from the Filchner-Ronne Ice Shelf in 1986 and is about 1,500 square miles — bigger than the entire state of Rhode Island.
News of A23a’s migration comes after reports of record-high heat that will define 2023 as the warmest year in 125,000 years. Over the past several decades, the Arctic has warmed four times faster than the rest of the world.

“The poles will determine the fate of humanity”
Or God.
“Not only coast lines, those pretty Red rocks in Sedona were underwater.”
True but those continental interior rocks were underwater due to tectonic forces uplift being the key force to bring them 4000+ feet above MSL, not eustatic sea level change due to ice volume. Most of the North American geological evidence will be in the Mississippi River Valley and all up and down the east coast’s River Valley’s up into the Appalachian forefront. All the evidence of the last glacial maximum sea level is miles off shore under 200+ feet of water. The earth’s sea level has fluctuated by 400+ feet from glacial maximum to interglacial minimums at least 4 times in the past few million years. Humans have only been humans 250,000 of that at most. Th at depends on how far back in the genius Homo. One considers anatomical humans. Modern Homo Sapien Sapiens are only 250k our older brothers Homo Sapiens add in 300 more thousand ish still humans couldn’t have caused any climate nonsense and we still don’t.

1. If all of the ice at the North Pole were to melt, sea level would rise EXACTLY ZERO because that ice already is floating in the water.
2. The mean temperature of Antarctica is -55°F, and the ice in places is THREE MILES thick. So it would take one hell of a lot of warming (and a hell of a long time) to melt it all.
3. The air above it isn’t what heats the oceans, it’s the earth beneath it.
One of the world’s largest and oldest icebergs is on the move.
Duh it’s what icebergs do when the cap get to crowded parts brake off and move.
If not ICEAGE
I hate when the ice melts in my water and it overflows....
Is this real science or political science (aka consensus).
6,400,000 cubic miles of ice in Antarctica and 139,382,879 square miles of ocean
That means there are 22 (rounding up) square miles of ocean per each cubic mile of ice.
Using acre ft. of water that works out to: 7,053 acre feet per square mile of ocean. or 11 acre ft per acre of ocean
Please correct my numbers if they are incorrect.
There will be penguins in the north pole soon.
Antarctica contains 7.2 million cubic miles of ice. I was off on the Greenland ice sheet it’s lost a bunch since the start of our current interglacial period at it’s peak during the Wisconsin era ice age peak it held 50 feet worth it’s only 24 feet now.
Here is a great summary of the cryosphere. Other than to commies it matters not. The earth swings from ice age to interglacial to even hot house earth conditions with zero continental glaciers . Humans have no effect on those cycles it’s a means for the commies to get control of the market economy pure and simple.
At some point voting is not going to solve the issue, history shows you have to shoot your way out of communism. People are too attached to their material things and their comfortable lifestyles to lose everything in a stand up battle which is exactly what is going to happen anyway. Better to choose the battlefield than to be forced on to it. Millions are just waiting for the balloon to go up and the gloves to come off. It’s when not if at this point plan accordingly.

Of course it has the obligatory climate change crap but you can’t publish anything without the approval of the bureaucracy.
Yes, ice is larger than liquid water, an oddity that is rare among materials.
Icebergs have 6/7 of their mass AND volume below the surface.
When they melt back into water, their mass remains the same, and the volume declines.
IOW, melting icebergs don’t make the seas rise.
