In the distance, we heard a crash as another slab of fractured glacier crashed into the water. Close to 70% of the world’s freshwater is locked into Antarctica’s snow and ice. Each cluster is counted three times in a row to ensure wandering penguins do not evade the census. In the 10 days since we had left, summer had taken a visible toll. The vessel was photographed between two walls of ice which had sheared off a glacier. The clip I filmed on my phone was partly obscured by other bodies. It was only 200 years ago, years after the invention of the steam engine and electric lighting, that humans first caught sight of Antarctica. Near the nunatak, a massive cruise liner was unloading Chinese tourists in rubber boats. Zafiro described a feedback loop that does not appear in climate models: the more the Antarctic is threatened by the climate crisis, the more tourists want to visit before it melts away. "I am excited to see this calving event after all these years. “People think Antarctica is isolated. Prior to our visit, the last survey of this island had been carried out in 1987, and since then chinstrap populations in other parts of Antarctica had suffered an alarming 50% decline. I turned in time to see the dorsal fin arc languorously out and back into the water just like a fairytale sketch of a sea serpent. The rate of advance peaked in the 1980s, after which it slowed down until about 1990. If there is something absurd about tour companies expending so much energy on crafting the illusion of solitude, it does at least help avoid overcrowding. On that day, on that island, the Antarctic was hotter than Cape Town. Everyone must keep their distance from wildlife – five metres from a penguin, 10 metres from a seal, 50 metres from a whale, unless they come to you. “The changes are so great it is hard to put them in words,” he said. Others, such as the humpback, suffered an estimated 90% decline. "While there is much to be concerned about in Antarctica, there is no cause for alarm yet for this particular ice shelf," Prof Fricker added. Both ice areas had shared the same rift system. Avian census-taking starts with satellites. Before then, sturdy, compact iceberg heads had a big advantage over other lettuces in ease of transport and use. Last-chance-to-see tourism becomes a self-fulfilling prophecy. A ripple, a sigh, then a soft splash behind my back. © 2020 BBC. Home to an airfield, two churches, the research bases of 10 countries and about 500 semi-permanent residents, this international community has often been cast as the last hope of humanity in dystopian novels and films because of its remoteness, collaborative spirit and focus on science. We couldn’t move – the coxswain had cut the boat’s engine a few minutes earlier in preparation for a hydrophone recording. In the 1980s, the world was horrified to discover that certain chemicals had thinned the ozone layer and opened up a vast hole above the Antarctic that was raising cancer risks and disrupting weather systems and ocean currents. The planet has just had it's warmest June on record, followed by the warmest July on record, consequently ice everywhere has been melting, from the glaciers of Greenland to the Himalayas. In bay after bay, and on island after island, animal populations were almost wiped out. Penguin guano is the only excrement that can be seen from space. That was a whopping 9,000 sq km in area. Their task was simple but enormous: counting penguins. Temperatures on the peninsula – the finger of land that points up from Antarctica towards South America – have risen by about 3C in the past 70 years, one of the fastest increases in the world. These Fortnite locations are changing. What's interesting is that much attention in the area had actually been focussed just to the east of the section that's now broken away. That is a myth,” Marcelo Leppe, the director of Chile’s National Antarctic Institute, had told me when I visited him the previous day in Punta Arenas, the capital of Chile’s southernmost region. A humpback whale off the Palmer Archipelago. And as the planet heats, the sound is getting louder. Photograph: HO/Brazilian Navy/AFP via Getty. Tourists travel by kayak near Half Moon island, Antarctica. Warm water has recently been recorded near the Thwaites Glacier grounding line—the location where the glacial ice rests on the seafloor. Hundreds of thousands of them. The calved block covers 1,636 sq km in area - a little smaller than Scotland's Isle of Skye - and is called D28. The population final count is not yet complete, but it is already clear that the chinstraps on Low are just as vulnerable as elsewhere. Series of before and after panoramas of Imja glacier taken five decades apart highlights dramatic reduction of Himalayan ice A very deep layer of ice … NASA’s before and after pictures show how much ice and snow was lost in just nine days. Over the next two days, the weather took a turn for the worse. The pilot cut the outboard engine to reduce noise while the scientist, Tim Lewis, dropped the hydrophone – essentially a waterproof microphone on a long cable – into the ocean. Days later, a continental high of 20.75C was measured at a monitoring station on Seymour Island. Even in tiny quantities, this soot darkens the white landscape, reducing its capacity to reflect sunlight and making it melt faster. .css-yidnqd-InlineLink:link{color:#3F3F42;}.css-yidnqd-InlineLink:visited{color:#696969;}.css-yidnqd-InlineLink:link,.css-yidnqd-InlineLink:visited{font-weight:bolder;border-bottom:1px solid #BABABA;-webkit-text-decoration:none;text-decoration:none;}.css-yidnqd-InlineLink:link:hover,.css-yidnqd-InlineLink:visited:hover,.css-yidnqd-InlineLink:link:focus,.css-yidnqd-InlineLink:visited:focus{border-bottom-color:currentcolor;border-bottom-width:2px;color:#B80000;}@supports (text-underline-offset:0.25em){.css-yidnqd-InlineLink:link,.css-yidnqd-InlineLink:visited{border-bottom:none;-webkit-text-decoration:underline #BABABA;text-decoration:underline #BABABA;-webkit-text-decoration-thickness:1px;text-decoration-thickness:1px;-webkit-text-decoration-skip-ink:none;text-decoration-skip-ink:none;text-underline-offset:0.25em;}.css-yidnqd-InlineLink:link:hover,.css-yidnqd-InlineLink:visited:hover,.css-yidnqd-InlineLink:link:focus,.css-yidnqd-InlineLink:visited:focus{-webkit-text-decoration-color:currentcolor;text-decoration-color:currentcolor;-webkit-text-decoration-thickness:2px;text-decoration-thickness:2px;color:#B80000;}}Losing bergs to the ocean is how these ice streams maintain equilibrium, balancing the input of snow upstream. Thick cloud cover briefly fell away to reveal this first image of icebergs breaking away from the Sulzberger Ice Shelf due to sea swell from the Tohoku Tsunami, which had originated 8,000 miles away about 18 hours earlier. Satellite data since the 1990s has shown that Amery is roughly in balance with its surroundings, despite experiencing strong surface melt in summer. The bridge of the Arctic Sunrise in Discovery Bay, Antarctica. The melting of floating ice as it makes contact with the ocean is a key reason why the glacier is coming unglued. Chinstrap penguins diving into the ocean. Our small motor dinghy was carrying seven passengers – a polar guide, two Greenpeace activists, two journalists, a camera operator and a scientist specialising in marine acoustics. Before the break, a rift across the Larsen C ice shelf had extended more than 100 miles in length, and just a few miles of remaining ice connected the nascent iceberg to the shelf. The shelf is essentially the floating extension of a number of glaciers that flow off the land into the sea. On 24 December 2019, the Antarctic probably suffered its worst one-day ice melt since records began, according to analysis by the University of Liège. They are deemed too small, too plain, too remote or too storm-battered. All rights reserved. As scientists scramble to calculate how long that will take, and politicians dither in their response to the crisis, the tourist industry has spotted an opportunity, offering punters the last chance to see the Antarctic before the continent as we know it disappears. Veterans of Antarctic exploration had warned me that this location would give me my first taste of how rapidly the region is warming. So, scientists knew this calving event was coming. Before-and-after pictures show how climate change is destroying the Earth ... which came from sediment deposited by Muir Glacier and by melting icebergs on the ground. Before leaving the Arctic, I drive to Point Barrow alone. In December, monitoring equipment at the Chilean research base on King George Island detected something that worried Leppe even more: black carbon in the air, which came from the Australian bushfires more than 6,200 miles away. Everyone listened with a similar expression of concentration and offered their own interpretation of these strange sounds. The tents withstood a cold night of wind and rain, but there was nothing anyone could do about the smell and the chatter.
