Lying 800 miles east off the Falkland Islands and a thousand miles north of Antarctica, it’s one of the few fragments of land between that vast frozen continent and the rest of the world.

How big is the world’s largest iceberg compared to London?
The part of the South Atlantic in which it sits is one of the most food-rich oceans in the world, fed by powerful circulating currents, and it’s full of shrimp-like Antarctic krill.
“Krill feeds the blue whales, humpback whales, fin whales. It also feeds the gentoo penguins, macaroni penguins, chinstrap penguins and the fur seals,” says Martin Collins, a scientist with the British Antarctic Survey, and former head of the South Georgia government, speaking to me from his office at King Edward Point on the island.
The island also has some of the largest and most significant populations of elephant seals, king penguins and several species of albatross and petrel – the hardiest of ocean-going seabirds.

Sky News to fly over world’s biggest iceberg
Concern over impact of iceberg on island’s wildlife
There’s a concern it could impact wildlife on the island – but the timing is fortuitous, says Mr Collins.
“It’s the end of the breeding season now, which means the impacts on penguins at that part of the island will be lessened.
“There may be a little bit of impact, particularly on gentoo penguins, which still forage around the island during the winter.”
From a wider conservation point of view, South Georgia is one of the world’s stand-out success stories.

Until the 1960s, it was a major hub for whaling. Thousands of whales were caught off its coasts and processed at a number of whaling stations – the scale of the slaughter such that the bays around the island were red with whale blood.
The whalers introduced reindeer for food that nibbled and trampled unique plant life that sustained many of the island’s endemic wildlife.
Stowaway rats plundered the eggs and chicks of penguins and other ground nesting birds (there are no trees).

World’s largest iceberg on collision course with South Georgia
Whales returning in large numbers
The South Georgia pipit, the world’s most southerly songbird, was driven to the brink of extinction.
But before the abandoned whaling stations have even rusted away, whales have begun returning to South Georgia in large numbers.
A campaign of air-dropping poisoned bait across the inaccessible island has eradicated the rats and the pipits are booming.
The seas around South Georgia were once heavily fished. The worst for wildlife were long-line vessels trying to hook high-value Chilean seabass.

Call for outright ban on fishing
Albatross and petrels would dive for the bait and be caught and drowned.
Since 2012, the government of South Georgia and the South Sandwich Islands have policed a 500,000 square-mile marine-protected area around the islands where most fishing is now banned.
A few vessels are licensed to catch shrimp-like krill and seabass but only in winter when most predators are absent and under strict controls.
Some conservationists are calling for fishing to be banned outright.
However, the South Georgia government argues it’s the income from limited fishing licences that allows them to protect and monitor the exclusion zone.
Crucial at a time when funding from central government is scarce and unlikely to increase.
The key threat now is the rapidly changing climate around South Georgia.
“There’s evidence that the distribution of krill is moving a little further south gradually over time,” says Mr Collins.
“We need to be really mindful of that changing climate.”
But he’s optimistic too. Despite warmer oceans, numbers of some species are booming. Especially whales and fur seals.
“I’ve just had two king penguins walking past the windows as we were talking,” he says.
“When I first came here in the late 1990s, there were no fur seals in this area at all. And now they’re everywhere around us”.
The US secretary of state has hailed a “tremendous amount of progress” on peace talks after the US and Ukraine delegations met in Geneva – but said that negotiators would “need more time”.
Marco Rubio said the meetings in Switzerland on Sunday have been “the most productive and meaningful” of the peace process so far.
He said the US was making “some changes” to the peace plan, seemingly based on Ukrainian suggestions, “in the hopes of further narrowing the differences and getting closer to something that both Ukraine and obviously the United States are very comfortable with”.
Mr Rubio struck an optimistic tone talking to the media after discussions but was light on the details, saying there was still work to be done.

Analysis: Rubio strikes an optimistic tone – but is light on detail
“I don’t want to declare victory or finality here. There’s still some work to be done, but we are much further ahead today at this time than we were when we began this morning and where we were a week ago for certain,” Mr Rubio said.
He also stressed: “We just need more time than what we have today. I honestly believe we’ll get there.”
Sky News’ defence analyst Michael Clarke said on the initial US-Russian 28-point peace plan that it was Donald Trump against the world, with maybe only Moscow on his side.

Is Trump’s plan a ‘capitulation document’?
Mr Rubio praised the Ukrainian attitude towards the talks and said Mr Trump was “quite pleased” after he previously said in a social media post that Ukraine’s leaders had expressed “ZERO GRATITUDE” for US efforts.
Ukrainian President Volodymyr Zelenskyy said in his nightly address on Sunday that there are signs that “President Trump’s team hears us”.
In a news release on Sunday evening, the White House said the day “marked a significant step forward”.
“Ukrainian representatives stated that, based on the revisions and clarifications presented today, they believe the current draft reflects their national interests and provides credible and enforceable mechanisms to safeguard Ukraine’s security in both the near and long term,” it claimed.
Despite diplomatic progress in Geneva the finish line remains a long way off
We’ve witnessed a day of determined and decidedly frantic diplomacy in this well-heeled city.
Camera crews were perched on street corners and long convoys of black vehicles swept down Geneva’s throughfares as the Ukrainians worked hard to keep the Americans on side.
Secretary of state Marco Rubio did not want to go into details at a press “gaggle” held at the US Mission this evening, but he seemed to think they had made more progress in the last 96 hours than the previous 10 months combined.
The Ukrainian leader Volodymyr Zelenskyy also seemed satisfied enough, posting on Telegram that there were “signals President Trump’s team is hearing us” after a day of “numerous meetings and negotiations”.
That said, we are a long way from the finish line here – something Rubio acknowledged when he said that any proposal agreed here would have to be handed over to the Russians.
At that point, negotiations to stop the war would surely get tougher.
President Putin has shown little or no inclination to stop the conflict thus far.
This, then, is the most important reason the Ukrainians seem determined to keep the Americans on side.
European leaders have presented a counter proposal to the widely criticised US-Russian peace plan, with suggestions including a cap on Ukraine’s peacetime army and readmitting Moscow into the G8.
This will only take place if the plan is agreed to by the US, Russia and Ukraine, and the G7 signs off on the move. Russia was expelled after annexing Crimea in 2014.
The counter proposal also includes US guarantees to Ukraine that mirror NATO’s Article 5 – the idea that “an armed attack against one NATO member shall be considered an attack against them all”.
The initial peace plan was worked up by the White House and Kremlin without Ukraine’s involvement, and it acquiesces to many of Russia’s previous demands.
It covers a range of issues – from territorial concessions to reconstruction programmes, the future Ukrainian relationship with NATO and the EU, and educational reforms in both Ukraine and Russia.
Footage geolocated by Sky News showed Russian soldiers walking through the Shakhtarskyi neighbourhood on the outskirts of Pokrovsk on Thursday.
The video sheds light on the situation in this key frontline area, as Russian forces slowly encroach on Myrnohrad, the satellite town to Pokrovsk, and one of its last remaining outposts.
Videos geolocated by Sky News show fighting intensifying in recent weeks, as Russian forces attempt to gain control of the towns and their network of road and rail intersections.
Gaining control here would give Russia a base from which to access key cities further north that form part of Ukraine’s “fortress belt”.
Russian forces are advancing from all directions, according to the Institute for the Study of War (ISW), with only one small opening to the northwest of Myrnohrad remaining.
Estimated to be only 3km wide by military experts, this withdrawal corridor is patrolled by Russian drone units which monitor the area for moving vehicles and those who may attempt to leave on foot.
Russian forces have been advancing on Myrnohrad since late October.

Video from a Ukrainian unit in Myrnohad, posted on 29 October, shows a Russian vehicle attempting to enter the town from the northeast. The tank is attacked and soldiers attempting to enter on foot are targeted.
Video posted on 3 November shows Russian forces on the ground in the south of the town.
By 8 November, Russian strikes begin to pummel the northeast of Myrnohrad, the location of many of the town’s high-rise buildings, at that time, held by Ukrainian forces.
George Barros, Russia Team & Geospatial Intelligence Team Lead at ISW, told Sky News that Russian strategy in Pokrovsk has been to erode Ukrainian logistical capacity using drones and artillery over the course of several months.
“After denying supply lines and degrading the frontline forces by essentially cutting them off from behind and starving them out in their positions, then the Russians move forward with their infantry and frontal assaults,” Barros explained.
Capture the flag
For a brief period, it looked as though Russian forces had captured Myrnohrad.
Videos posted on 13 November appeared to show a Russian flag flying over the Myrnohrad mine.
However, video posted the following day showed a Ukrainian drone shooting it down.
Both Russian and Ukrainian forces continue to fight for control of Myrnohrad, with videos posted on the 19 and 20 November showing Russian airstrikes on Ukrainian positions in the town, and Ukrainian drone strikes targeting Russian forces on foot.
While the exact numbers of Russian and Ukrainian forces in the area remains unclear, reports indicate that three key Russian units are active in Pokrovsk and Myrnohrad, and are advancing on the towns from the north and south.
A number of Ukrainian units remain inside the towns, including the 145th Assault regiment and the 32nd, 35th, 38th and 155th Brigades. Reports indicate that more Ukrainian units have been moved into surrounding areas to hold the withdrawal corridor open.
Sky News reached out to the Ukrainian brigades still in Myrnohrad, but they declined to comment, citing military regulations.
Strategic significance
Natia Seskuria, associate international security fellow at the Royal United Services Institute (RUSI), explained that the area is important for the Ukrainians to keep and the Russians to take because of its strategic position.
“Situated at a major road and rail intersection in Donetsk Oblast, Pokrovsk has functioned as a central artery for moving troops, equipment, and supplies to Ukrainian units deployed along the surrounding front.”
Russia “would gain a platform to redirect its offensive efforts toward Ukraine’s principal defensive urban centres… including Kramatorsk and Slovyansk,” Seskuria said.
Ukrainian and Russian soldiers in Pokrovsk have fought intensely and at close quarters over the last month.
In late October US-made Black Hawk helicopters containing specialist troops directed by Ukrainian military intelligence entered Pokrovsk to try to keep the town.
But as Russian troops advance, Myrnohrad is becoming the last stronghold of Ukrainian forces in the area.
Uncertain future
At least up until 12 November, there were still civilians living in Pokrovsk and Myrnohrad, despite strikes on buildings in both cities.

A post made on that day by the Donetsk state regional administration estimated 1,200 people remain living in Pokrovsk and 900 in Myrnohrad.
Evacuation is only possible with the help of the military or police, and it is not clear how many have evacuated in the 11 days since.
Barros of ISW says gaining Pokrovsk would increase Russia’s leverage at the negotiating table.
“If the Russians can successfully convince enough international leaders that, okay, the Russians took Pokrovsk, they’re going to take the next thing, and they’re going take the thing, so now let’s negotiate, then that is a strategic victory for the Russians.”
