South Georgia Island is where Shackleton and his small crew landed, intentionally, in a storm using only dead reckoning in a lashed together boat, then did a never-before attempted 36 hour wintertime crossing over the island from the remote side to the populated side in the dead of winter.
They had to do this because their exploration ship, the Endurance, got crushed and sank as they attempted (again) to trek to the south pole.
One of the most amazing things about it is there are a lot of photographs from the ordeal. Despite barely getting off the ice floes and having a low chance of living, they carried with them hundreds of pounds of glass photographic exposures. Why? Because if they lived, publication rights of their stories and the photographs were necessary to pay off the debt they incurred in undertaking the mission.
I know this can potentially sound very stupid given the actual size, but can't we bomb it (target specific parts with a lot of firepower) in an attempt to break it up if it poses such a danger to actual wildlife if it collides/approaches the island? The ocean then potentially will carry some of the pieces away and miss the island?
Why do people always feel the need to interfere with nature? Looking at their diagram of penguin colonies it looks like at most 40% could be blocked from the sea by this iceburg. Yes it will suck for the half of the island that gets wiped out but in 10 years when this thing is melted and gone the penguins from the other side will reestablish colonies and life will go on.
This thing is the size of Jamaica with a draft of 200m (and so a height of more than that). It would take multiple nuclear weapons to do it any real kind of damage.
Beautiful page, but I still don't get why it's a big deal? Iceberg gets stuck next to an island - surely it won't completely envelop it. The map shows the island is dotted with penguins breeding grounds so not all are going to be blocked, probably way less than half even. In the area where it will drag on the seabed some of the life will be probably destroyed, but this area can't be very large compared to the size of the island.
I mean it would be better if it doesn't happen but compared to the other climate catastrophes we're facing this doesn't seem very serious. Surely, penguins can deal with some floating ice?
The article explains several other effects to wildlife that you are skipping over. Namely, disruption to coastal food chain by melting freshwater, and the longer round trip for penguins feeding their chicks.

some floating ice ??
The "beautiful page" has plenty of diagrams explaining the extent of this ice. It is the size of Jamaica. The largest floating ice object in recorded history.
The iceberg is very large, so even if it doesn't envelop the island it could create a detour of up to 140km between a penguin and its feeding waters, a 280km addition to every trip - and that's only if it has access to satellite images to plan its route. On the surface, that penguin would only see a huge wall of ice with no indication which way would be shorter.
The mass is now moving straight toward a remote south Atlantic island populated by penguins and seals. Scientists say a collision could cause an environmental catastrophe
It's the size of Jamaica and could plow through the near shore sea bed, and block off access to feeding grounds for the penguins on the island. Basically everything below the water will be crushed, and everything on land will starve.
> "What we’re particularly worried about is that this iceberg doesn’t have a very deep keel,” Tarling said. “So the amount of iceberg under the water isn’t as much as you would normally expect for an iceberg like this.”
If this thing is a massive ice cube floating in the sea then surely they know how much of it is under the water?

Today's images are pretty clear as there's not much cloud cover
