This isn't the first time an iceberg has sloughed off Antarctica.

Antarctica is about to lose an iceberg 30 times the size of Manhattan as two cracks converge — and it could cripple a British research station

NASA is tracking two converging cracks in Antarctica's Brunt Ice Shelf. When they meet, an iceberg 30 times the size of Manhattan could float away.
A gigantic cavity nearly 1,000 feet tall is growing at the bottom of Thwaites Glacier in west Antarctica.

There’s a cavity underneath Antarctica that’s two thirds the size of Manhattan — a sign ice sheets are melting faster than we though...

Nearly 14 billion tons of ice have melted underneath Antarctica's Thwaites Glacier, leaving an almost Manhattan-sized cavity beneath the surface.

Antarctica’s monster A68 iceberg is still alive — but the Maryland-size ice block just pivoted toward its doom

Antarctica's A68a iceberg, the continent's sixth-largest in recorded history, is still floating more than a year after it broke off. It weighs about 1 trillion tons, is about the size of Maryland, and is mostly intact. However, the ice block just made a big and fatal turn.

Watch a Delaware-size iceberg break off Antarctica and float away in an incredible new animation

See one of Antarctica's largest icebergs in history being born and how it's moved in nine months' worth of satellite images compressed into 10 seconds.

Scientists say the Delaware-size iceberg that broke off Antarctica could have happened without global warming

There's no direct evidence that rising temperatures caused iceberg A-68 to calve. But some scientists are pushing back on claims that it was a "natural" event.

What the world would look like if all the ice melted

These maps reveal what the world could look like if the worst climate change predictions come true.

A surprisingly subtle force may have broken off one of the largest icebergs ever recorded

Antarctica researchers say little puddles of water can add up to an effect that can destabilize entire ice shelves.

Antarctica’s new 1.1-trillion-ton iceberg is already breaking into enormous pieces

New satellite images of iceberg A68, which calved from Antarctica's Larsen C ice shelf, shows it has already broken in two.

Antarctica’s colossal new iceberg is doomed — here’s what will happen next

Here's the story of the Larsen C ice shelf's iceberg A68, which scientists say has left "the landscape of the Antarctic Peninsula changed forever."

Antarctica just shed one of the largest icebergs the world has ever seen — these size comparisons reveal how big it really is

The scale of Antarctica's new 1.1-trillion-ton iceberg boggles the mind when compared to more familiar objects and locations.
