    It's at the heart of Antarctica and on the verge of collapse.

    Man-made climate change is warming the planet's atmosphere and oceans, and the effects are being felt the most at the poles. In Antarctica, home to the largest chunk of ice on earth, ice shelves and glaciers are beginning to collapse, and one in particular could spell disaster. The Thwaites Glacier, in West Antarctica, has retreated more than 14 kilometers in the last two decades as warm ocean water undermines it. The glacier is situated on a downward slope that falls deep into the center of Antarctica. It's why scientists are racing to find out how close it is to total collapse - and what that would mean for future sea levels.

  • Were melting the Arctic and reviving deadly germs

    3:26

    Beware the thawing permafrost.

    Become a Video Lab member!

    In the coldest parts of the world, there’s a layer of soil that stays frozen all year. This layer is called permafrost; it exists mainly around the Arctic, and acts kind of like a giant freezer. As plants and animals in those regions die, some of them become preserved in this permafrost.

    But as human activity releases greenhouse gases into the atmosphere, the permafrost is starting to thaw and shrink. That’s having some dramatic consequences — and not just for people who live in the Arctic.

  • Rising threat from the seas | DW Documentary

    42:26

    How high will the oceans rise due to climate change? The projections are the subject of dispute, with scientists continually correcting their estimates upward. Is this just panic-mongering or are these scenarios within the realm of possibility?

    Can we make any reliable predictions about the world’s oceans? If all the ice in Antarctica and Greenland were to melt, sea levels would rise by more than 66 meters. The consequences for coastal populations are gradually becoming clear. By 2100, coastlines around the world could change radically. The research being conducted by marine scientists will decide how affected regions can prepare for the disaster on the horizon. At what point will governments have to consider evacuating areas on the basis of cost-damage analyses? It is a process that has already begun in places like the United Kingdom.

  • The story behind this iconic Olympics protest

    9:10

    Tommie Smith and John Carlos’s 1968 US national anthem protest, explained.

    Become a Video Lab member!

    The image of sprinters Tommie Smith and John Carlos raising their fists during a medal ceremony at the 1968 Olympics in Mexico City is an enduring image of silent protest. But the key to understanding it goes beyond the black-gloved fists. All three medal winners, including silver medalist Peter Norman of Australia, wore buttons that read “Olympic Project for Human Rights.” The Olympic Project for Human Rights (OPHR) was a coalition of prominent athletes formed in 1967 that threatened to boycott participating in the upcoming Olympic games, in order to draw attention to systemic racism in the United States. The group, led by professor Harry Edwards, ultimately voted to compete in the games and hold their demonstrations there, which led to the now-iconic display on the medal stand following the men’s 200-meter final. This act got Smith and Carlos kicked off the team, but left a lasting legacy on making political statements through sport.

  • The fight for Americas 51st state, explained

    7:22

    Washington, DC is closer than ever to becoming a state. Could it actually happen?

    Subscribe to our channel!

    On June 26, 2020, the US House of Representatives voted to make America’s capital city, Washington, DC, the country’s 51st state. It was a historic vote, and the closest the country has come to adding a new state in over 60 years. But it was also, for the time being, completely symbolic. Because at least in 2020, DC has no chance of actually becoming a state.

    That June 26 vote was almost entirely along party lines; Democrats mostly voted in favor of DC statehood, and Republicans against it. That’s because making DC a state would give the Democrats additional seats in Congress, potentially affecting the balance of power between the parties. It’s why President Trump and the Republican-controlled Senate have both promised to strike down any bid for DC statehood. And in fact, statehood in the US has always been a political issue. In the past, the US has often added states in pairs to preserve the political balance. Admitting a new state on its own has happened, but it’s unusual.

    But the case for DC statehood is strong: The city has a similar population to several states, its hundreds of thousands of residents lack any say in national lawmaking, and its local government is uniquely vulnerable to being strong-armed by Congress and the federal government. Simply put, the laws that created the district did not anticipate that it would one day be a major city. And while in 1993, the last time Congress voted on DC statehood, the Democratic-controlled House failed to pass it, today’s Democratic Party is increasingly on board with it. If 2020’s election puts the Democrats in full control of the federal government, America might actually get its 51st state.

  • A Million Dollars vs A Billion Dollars, Visualized: A Road Trip

    1:19:08

    There are lots of ways to compare a million to a billion, but most of them use volume. And I think that's a mistake, because volume just isn't something the human brain is great at. So instead, here's the difference between a million and a billion, in a more one-dimensional way: distance.


    REFERENCES:
    Humphrey Yang's rice TikTok:
    and his YouTube channel:

    The Corridor Crew billion video:


    FAQ:
    Q: Is this accurate?
    A: Yes. The GPS track on the GoPro wasn't great, though, so the walking sections had to be manually smoothed out. For the main car drive, I relied on a backup GPS tracker taking a sample every 1 second. That data was loaded into an After Effects expression, set to $1 per 0.1093mm. If it couldn't pick up a GPS reading (for example, in the Chestfield Tunnel), it waited until signal returned and then calculated an average speed for the gap. There was one correction: during a stop next to a large lorry, the GPS lost tracking and wandered about 50m in a random pattern while the car was completely at a halt. Those errors were removed.

    Q: Why is this in 50fps?
    A: The electricity grid in the UK runs at 50Hz, which means that you can get strobing effects from lighting. Normally that wouldn't matter on something filmed outside, and I'd go with 60fps, but I didn't want to risk full-screen strobing in the tunnel section. (You do still see strobing on some variable message signs, but that's for different technical reasons.) As 24/25fps feels too slow and jerky for a continuous dashcam shot, this was the best option.

    Q: Why did you do this with American dollars in the UK?
    A: The Bank of England doesn't produce a £1 note. The smallest paper money we have is £5. (The Royal Bank of Scotland, and the banks of some of the Channel Islands, do though!) And while it would have been apt to do this along desert roads in California, sometimes you've got to make do with what's available.

    Q: What was that oops about a minute into the drive?
    A: I nearly turned left one junction too soon, which would have sent me to a closed barrier and ruined the take.

    Q: Why do you change lanes so much?
    A: In the UK, the correct thing to do is to always switch to the leftmost possible lane after overtaking on a motorway, unless there's another car you'll have to overtake soon or you're approaching a slip road. This means you have to change lanes a lot more than in many other countries. Source:

    Q: You pass a van on the left at one point. Is that legal?
    A: Deliberately passing on the left (undertaking) in the UK is considered dangerous driving on non-motorways and in free-flowing motorway traffic. However, in congestion when traffic is slowed down, keeping up with traffic in your lane is fine. Source:

    Q: What do those white signs with a black stripe mean?
    A: National speed limit applies. On dual carriageways (divided highways), that means 70mph; on other roads, it's lower. Alas, it does not mean no speed limit like it does on the German autobahn.

    Q: What does the signs with the white C in a red circle mean?
    A: Those are reminders about the Dart Charge, the £2.50 toll for crossing the Thames at Dartford.

    Q: How many attempts did this take?
    A: Three. Attempt one was ruined by the time of day: I was travelling east in the morning -- so all the camera could see was glare from the sun and the dashboard reflected in the windscreen. Attempt two was ruined by the camera overheating shortly after the Dartford Crossing. (That's why this is in 2.7k, not 4k, and why you can hear wind noise from the air conditioning blowing over the camera to keep it cool.)

    Q: How can this be an FAQ when you wrote it before the video went live?
    A: In this case, FAQ stands for Fully Anticipated Questions.

  • Antarctica melting: Journey to the doomsday glacier - BBC News

    3:00

    Glaciologists have described Thwaites Glacier as the most important glacier in the world, the riskiest glacier, even the doomsday glacier.

    A team of 40 or so scientists are part of the International Thwaites Glacier Collaboration, a five-year, $50m (£38m) joint UK-US effort to understand why it is changing so rapidly.

    The project represents the biggest and most complex scientific field programme in Antarctic history.

  • Why a pink glacier in northern Italy has scientists worried

    2:05

    Why a pink glacier in northern Italy has scientists worried

    Scientists are worried about a glacier in Italy that is turning pink due to algae that will make the ice melt faster.
    Pink snow has appeared at the Presena glacier in northern Italy, researcher Biagio Di Mauro, of the Institute of Polar Sciences at Italy'sNational Research Council, told CNN yesterday.
    While watermelon snow, as it is sometimes known, is common in the Alps in spring and summer, it has been more marked this year.
    When Dr Di Mauro went to the glacier on Saturday to investigate, there was quite an impressive bloom of snow algae, he said.
    He told CNN he believes an algae named Chlamydomonas nivalis is responsible for the change in colour.
    This spring and summer have seen low snowfall and high atmospheric temperatures, Dr Di Mauro said, adding: This creates the perfect environment for the algae to grow.
    Algal blooms are bad news for the health of the glacier as darker snow absorbs more energy, meaning it melts faster.
    It is for sure bad for the glacier, Dr Di Mauro said.
    The phenomenon has been particularly common this year, said Dr Di Mauro, who plans to study it in more detail to work out the concentration of the algae and map the blooms using satellite data.
    Dr Di Mauro has previously studied the Morteratsch glacier inSwitzerland, where an alga called Ancylonema nordenskioeldii has turned the ice purple.
    This alga has also been found in southwestern Greenland as well in as the Andes and Himalayas.
    Glaciers around the world are melting as a result of climate change.
    In October 2019, research revealed glaciers in Switzerland have shrunk 10 per cent in the past five years, a rate that has never been seen before in more than a century of observations.
    In Antarctica, the giant Denman Glacier has retreated almost three miles in the past 22 years, according to research published in March.
    If it melts completely, sea levels will rise almost five feet, the researchers said.

    Now, here is another worrying report on global warming....
    Glaciers on Mount Everest have shrunk by more than a quarter over the past 40 years due to climate change.
    This is according to a joint report released by the Chinese Academy of Sciences in conjunction with a local university and conservation center.
    It says the glaciers have been reduced by 28 percent compared to measurements taken in the 1970s.
    The glacial area on the south slope of the world′s tallest mountain has decreased by a massive 26 percent since the 1980s.
    The shrinking glaciers have resulted in the swelling of many glacial lakes.

  • Melting Mountain Glaciers -- Changing Planet

    6:45

    The world's glaciers are shrinking at alarming rates, and many scientists believe it is due to changes in climate. Dr. Lonnie Thompson of Ohio State University and Dr. Douglas Hardy of UMass-Amherst discuss glaciers and how they melt, and pay special attention to Africa's tallest mountain, Mt. Kilimanjaro.

    The Changing Planet series explores the impact that climate change is having on our planet, and is provided by the National Science Foundation ( & NBC Learn (

  • Why I dont care about Climate Change | David Saddington | TEDxTeen

    13:11

    This talk was given at a local TEDx event, produced independently of the TED Conferences. You don't care about climate change right? Because it's a bunch words of things that don't affect your daily life. Think again. In this provocative talk, Saddington gives us a new lens on climate change. It's a game changer.

    Influencing UK government policy, establishing his own social enterprise and fronting a media campaign that reached over 3 million people are just a few of David’s achievements as a climate change activist since being impacted by a stark reminder of climate change as a teenager.

    From a meeting with then Prime Minister Tony Blair at 10 Downing Street, he discussed the implementation of climate change on the national curriculum. Climate change is now an essential part of youth education and he has pushed to expand these education reforms worldwide.

    As a Three Dot Dash Global Teen Leader, he has expanded his philanthropic and award-winning social enterprise, which has developed eco gardens across Northern England and within the historic grounds of Durham University.

    David has acted as an environmental consultant for countless organisations and is a regular commentator on contemporary climate issues within academic arenas and international media outlets. He has studied the science of climate change at Durham University for 3 years and led a groundbreaking glacier survey expedition to Vatnajökull, Iceland. His most recent venture transformed the medieval Market Square of Durham City into an outdoor cinema to showcase the award-winning documentary Chasing Ice. He then chaired ‘Climate Change Question Time,’ where the public could grill world leading climate experts on the science behind the headlines and how to tackle the problem.

    David believes that we must act as a species rather than via fragmented interests in order to tackle this remarkable global disruptor.

    About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

    12. Scientists climbing up mountain
    13. Scientist with water measure instrument
    14. SOUNDBITE: (Spanish) Edouard Perroy, French Glaciologist:
    This glacier, Zongo Huayno Potosi in Bolivia has been reduced by more than 250 metres in length and from 50 to 100 metres in depth depending on the specific part of the glacier - and this glacier is extremely important for the city of La Paz.

    16. Exterior shot of IHH - Institute of Hydraulics
    17. Set up shot of Patrick Ginot, French Glaciologist
    18. SOUNDBITE: (French) Patrick Ginot, French Glaciologist
    Andean glaciers are melting, so today those glaciers are producing more water from the source, but as those glaciers are going to melt, the water resources are going to decrease and there will be a loss or a lack of water in big Andean cities.
    19. Various of posters saying glaciers are shrinking
    20. SOUNDBITE: (French) Patrick Ginot, French Glaciologist:
    In the Bolivian case, the disappearance of glaciers is going to create changes in the accessibility of water - and Bolivia is going to have to work out how to adapt itself to those calendar changes in resources. So one of the possible solutions would be to replace the glacier, which is a water reservoir, with an artificial reservoir which collects water during the rainy season and which can then be liberated throughout the year.
    21. Various of traffic in La Paz
    El Alto
    24. Various Javier Alvaro Lania collecting water
    23. SOUNDBITE: (Spanish) Javier Alvaro Lania, Slum Dweller:
    We have public water supply here and we suffer a lot because of it. They only give us certain times to get water - from 6 in the morning til 9 in morning.
    24. Various boy collecting water
    25. SOUNDBITE: (Spanish) Javier Alvaro Lania, Slum Dweller:
    I heard on the news that Huayno Potosi has gone down a lot - the snow that usually supplies us. We heard on the news. And we're really worried.
    26. Mid Aymara women filling buckets
    27. SOUNDBITE: (Spanish) Maria Sol, Slum Dweller:
    There is no water here really. Just the public tap. We have a hard time with this. When we wash our clothes its difficult for us to carry water home - we fill up big buckets but its hard.
    28. Close up of bucket being filled with water
    LEAD IN:
    Some of Bolivia's poorest people may lose their basic water supply to global warming.
    Residents of El Alto in La Paz, Bolivia rely on the Huayna Potosi glacier in the Andeas for their water.
    But as scientists predict that all the glaciers in the tropical Andes will disappear by mid-century, the population of El Alto face an uncertain future.
    STORYLINE:
    El Alto - Bolivia's vast slum area - is home to nearly a million people, mostly indigenous.
    Towering more than 4000 metres above sea level, the slum city is the result of an urban overspill of rural migration to Bolivia's administrative capital La Paz.
    People here live in humble conditions - most have no running water of their own.
    So they make the trip to the public tap to fill their containers twice a day.

  • Climate change: Fact or fiction? | Head to Head

    47:33

    Some scientists say the earth's climate changes constantly and naturally, but the vast majority of them believe the current rise in global temperature is man-made, and could be catastrophic for the planet. But is all this but a case of extreme ‘climate alarmism'? Climate change sceptic Richard Lindzen is challenged on his view that concern about global warming is alarmist nonsense.

  • The Glacial Rate of Breakneck Change: A Personal Perspective of Computer Architecture

    1:38:08

    [Recorded on September 28, 2004]

    It's really easy to equate the breathtaking exponential growth in computing technologies with an underlying innovation in computing architecture. Nothing could be further from the truth. In this unabashedly personal perspective of our living computer history, Greg Papadopoulos distills what has -- and hasn't -- been happening in the design of computers over the past few decades, and uses that to make some predictions as to what the next few will bring. He discusses that, when you boil it all down, there are perhaps only four or five basic ideas in computing; everything else we experience are (just) constant factors.

    FRANCE 24 live news stream: all the latest news 24/7


    It's not too late to save the ice on the Alps, but action has to be taken now. That's the warning from Swiss scientists who say that at the current rate, there could be no glaciers left at all on the Alps just 81 years from now. That would mean 40 million Olympic-sized swimming pools of ice would have disappeared, with devastating consequences for the environment and the economy. We spoke to climate scientist Harry Zekollari from the Swiss Federal Institute of Technology in Zurich.

  • What Are We Protecting Mars From — And Why Do We Bother?

    1:20:00

    Mars, the small, cold fourth rock from the Sun, is being given serious consideration by 21st century explorers. Entrepreneur Elon Musk has ambitious plans to send humans to the Red Planet within seven years (and bring them back again); NASA has flown both rovers and landers; and NASA, the European Space Agency, and China have announced plans to each add a rover to the mix in 2020. Even India has orbited Mars, and others such as the UAE are developing their own orbiters. The planned 2020 rovers are part of a strategy that will include bringing samples back from Mars’ surface to Earth.

    NASA’s Planetary Protection Office was created to “promote a responsible exploration of the solar system by implementing and developing efforts that protect the science, explorers, environments, and Earth.” This has been the agency’s policy, reflecting the non-contamination provisions of the UN Outer Space Treaty of 1967. Now, some scientists question the need for restrictive contamination guidelines, arguing that new exploration, and in particular a direct search for life in the best places on the Red Planet, is being impeded. Is planetary protection slowing down exploration, and the search for life beyond Earth? Do we have the right to send robotic machinery, or even people, to Mars without giving biologists a chance study it, and look for life? What if that life is hidden underground from view, and requires humans to find it?

    In April’s SETI Talk, Robert Zubrin, president and founder of the Mars Society, and John Rummel, former NASA Planetary Officer and currently a Senior Scientist with the SETI Institute, will participate in an animated (and lively!) discussion on these issues, moderated by Seth Shostak, Senior Astronomer.

    Dr. John Rummel is a Senior Scientist with the SETI Institute, and chairs its Scientific Advisory Board. He is the former Chair of COSPAR's Panel on Planetary Protection. Rummel has previously worked at NASA Headquarters as NASA's Senior Scientist for Astrobiology and as the Planetary Protection Officer. He is a Fellow of the American Association for the Advancement of Science (1990), the recipient of the Life Sciences Award from the International Academy of Astronautics (2005), and was awarded the NASA Exceptional Performance Award in 2008.

    Dr. Robert Zubrin, formerly a staff engineer at Lockheed Martin Astronautics in Denver, is now president of his own company, Pioneer Astronautics. He holds masters degrees in aeronautics and astronautics, as well as a doctorate in nuclear engineering from the University of Washington. He is a Fellow of the British Interplanetary Society and former Chairman of the Executive Committee of the National Space Society and the founder of the Mars Society; an international organization dedicated to furthering the exploration and settlement of Mars by both public and private means.

  • Landmark College Presents: Dr. M Jackson - The Secret Lives of Glaciers

    1:4:26

    Dr. M Jackson explores what happens to an Icelandic community as their local glaciers disappear. Profoundly hopeful, Jackson’s talk shows how ice influences people just as much as people influence ice.

    Dr. M Jackson is a geographer, adventurer, TED Fellow, and National Geographic Society Explorer. M earned a doctorate from the University of Oregon in geography and glaciology, where she examined how climate change transformed people and glacier communities in Iceland. A veteran three-time U.S. Fulbright Scholar to Turkey and Iceland, M currently serves as a U.S. Fulbright Ambassador. M also serves as an Arctic Expert for the National Geographic Society over the last nine years, holds a Masters of Science degree from the University of Montana, and served as a Peace Corps Volunteer in Zambia.

    She’s worked for over a decade in the Arctic chronicling climate change and communities, guiding backcountry trips and exploring glacial systems. Her 2015 memoir While Glaciers Slept: Being Human in a Time of Climate Change weaves together the parallel stories of what happens when the climates of a family and a planet change. Her 2019 book, The Secret Lives of Glaciers, explores the profound impacts of glacier change on the human and physical geography of Iceland. She is currently at work on In Tangible Ice, a multi-year, multi-disciplinary project partnering with explorers, filmmakers, and scientists that examines the socio-physical dimensions of glacier retreat in near-glacier communities within all eight circumpolar nations.
