As the southern hemisphere enters summer 2025, much of Antarctica is predicted to melt and vaporize; and Heating Planet blog will be tracking South Pole events and posting every relevant and informative video that comes up. Watch: Cosmos Driver channel report Sept 15: Antarctica Is Melting Faster Than Ever A Warning for Our Future "Some parts of Antarctica are experiencing temperatures more than 10° C above seasonal averages. These events were once unthinkable but are now becoming more common, signaling how climate extremes are reaching even the coldest places on Earth."- transcript and blogger note below:
[Music] 0:06 Antarctica, the southernmost continent 0:08 on our planet, is often imagined as a 0:11 remote wilderness of endless ice. But in 0:15 reality, it is one of the most important 0:17 places on Earth, shaping our climate, 0:20 oceans, and even our future. 0:25 [Music] 0:36 [Music] 0:39 Covering about 14 million square kilm, 0:42 Antarctica is larger than Europe and 0:45 nearly twice the size of Australia. 0:48 Almost the entire continent is covered 0:50 by ice. Some of it more than 4 km thick. 0:54 Locked within this ice is nearly 90% of 0:58 Earth's fresh water, making Antarctica a 1:01 giant frozen reservoir. Its presence 1:04 keeps our planet cooler because the 1:07 bright white surface reflects sunlight 1:09 back into space, a process called the 1:13 albido effect. The surrounding southern 1:16 ocean also acts as a giant climate 1:18 regulator, absorbing heat and carbon 1:21 dioxide and influencing global ocean 1:24 currents. 1:32 [Music] 1:47 Yet, this frozen world is undergoing 1:50 dramatic change. In recent years, 1:53 scientists have recorded record lows in 1:55 sea ice cover and the weakening of 1:58 massive ice shelves. When ice shelves 2:01 collapse, they remove the barriers that 2:04 hold back glacias, allowing ice to flow 2:06 more quickly into the ocean. This speeds 2:10 up sea level rise, threatening coastal 2:13 communities far from Antarctica. 2:18 [Music] 2:29 Wildlife is also deeply affected. 2:32 Emperor penguins, which depend on stable 2:35 sea ice to raise their chicks, are 2:38 suffering major breeding failures as the 2:40 ice melts too soon. On the Antarctic 2:43 Peninsula, some Adeli penguin colonies, 2:46 have declined by up to 90%. 2:49 Even krill, the tiny shrimplike 2:52 creatures that form the base of the 2:54 Antarctic food web, are shifting their 2:56 ranges as the ocean warms and sea ice 3:00 retreats. 3:02 [Music] 3:09 Another surprising change is the 3:12 so-called greening of Antarctica. 3:15 Mosses and small plants are spreading 3:18 across parts of the Antarctic Peninsula 3:20 where ice is retreating, transforming 3:23 landscapes that were once barren. While 3:26 this may seem like a small change, it is 3:29 a powerful sign that ecosystems are 3:32 shifting in response to warming 3:34 temperatures. Scientists are also 3:37 warning about invasive species that 3:39 could take advantage of these changes, 3:42 disrupting the delicate balance of 3:44 native life. 3:47 [Music] 3:52 Heat waves have also been recorded with 3:55 some parts of Antarctica experiencing 3:58 temperatures more than 10° C above 4:01 seasonal averages. These events were 4:03 once unthinkable but are now becoming 4:06 more common, signaling how climate 4:09 extremes are reaching even the coldest 4:11 places on Earth. 4:16 [Music] 4:21 What happens in Antarctica doesn't stay 4:23 in Antarctica. Melting ice sheets 4:26 contribute to global sea level rise. 4:29 Changes in ocean circulation around the 4:31 continent can alter weather patterns 4:33 across the globe. From monsoons in Asia 4:36 to storms in North America. 4:42 [Music] 4:50 In short, Antarctica is connected to all 4:53 of us. In conclusion, Antarctica is more 4:57 than an icy wilderness at the end of the 4:59 Earth. It is a vital part of our planet 5:03 system. a giant mirror, a climate 5:06 regulator, a home for unique wildlife, 5:09 and a warning signal for the future. 5:12 Protecting Antarctica means protecting 5:14 the balance of our entire planet. It 5:17 reminds us that even in the most distant 5:20 and frozen corners of the world, the 5:22 changes we create can ripple outwards 5:25 and return to shape our own lives. 5:30 [Music] 5:38 Stay curious, stay informed, and let's 5:41 remember that what happens in Antarctica 5:44 will shape the future of us all. 5:49 [Music]
