How did Earth get its coastlines? Neil deGrasse Tyson and comedian Chuck Nice explore prehistoric coastlines, the Ice Age, and why Florida is temporary. Why does the shape of the coastline change?
Learn about the continental shelf and how the Ice Age impacted the oceans. What did Earth’s coastlines look like during the Ice Age? Find out about the Bering Strait Land Bridge and how early humans may have used it to cross into the Americas. We discuss how civilization grew in stable climate and how that will change over time.

I don't get people who get on Chuck. He is consistently funny. Very respectful, and doesn't constantly interject in an annoying manner like other comedians they have worked with. Some of those guys are nonstop, and the scientist can barely get a word in. Chuck usually interjects with well placed, well-timed humor. But the best thing about Chuck is, there are moments, where he really shows his intelligence outside of his quick whit, and either says things or sums things up very well.Just had to say that after seeing people disrespect him in other videos.

I live close to the glaciers in the Canadian Rockies. We're supposed to have a few hundred years of ice pack to stock our water supplies at current melt levels (see Columbia Glacier...which I have seen retreating all my life during family visits since I was 3). The retreat of the glacier is pretty dramatic. But, there are still hundreds of meters of ice up high. When flying to the coast, you can still see lots of white (and clear cuts). I don't know how much water that would equate to if all melted into the ocean. To the south in Montana, the Grinnell Glacier was pretty famous when I was a kid and now it is completely gone. The past few years have seen rainfall dwindle and we're expecting a crazy dry year. Farmers are bracing for drought. Our skies have turned red a few times with all the forest fires.

Saddly a "crude" reality we have to deal with. Here in the Caribbean I'm not that "optimistic" at all. Most of the island have little beach coast. So, we have to move to the central mountains to survive. All the cities at the coast well be gone and most likely half of the population at least. About 44 towns (about half of the population.... 1.5M persons) are at the coast line. Mother nature didn't have VIP's for nobody, so everybody should be taking steps toward our survival as in humans for the generations to come, regardless of the place on the earth you live. My two cents....

They aren't afraid to spend billions building along the Coast. We also noticed yesterday that we have 2 new Islands reappearing in the Indian River that we can see crossing the bridge. The Indian River and the Banana Rivers are both fed from the Atlantic Ocean and are considered brackish rivers because they also are fed from fresh water sources. What I have noticed is the normal twice annual flooding around Miami that is caused by the King Tide is now being used as evidence of riding seas due to Climate Change. Those annual events have been occuring long before Climate Change was cool. The Florida Keys are all still there and haven't shrunk in size.

I was thinking the exact same thing. Like yeah, the coastline today wasn't the same as it was a million years ago, but there's nothing special about today that says this is how our coastlines are "supposed" to look. I never considered that the continental shelf took the shape of the coastline because they USED to be the coastline. I had always thought of them as being solely part of plate tectonics.

Just to add... It's not just the melting of sea ice or glaciers that's causing the rise in sea levels. Something like 30% to 40% is caused by thermal expansion. As heat gets trapped, and the oceans warm up, the volume of water expands.

@@thejuanderful - Not just Atlantis. Plenty of old myths and stories about the Flood, a lot from different cultures around the globe too. And later stories from ancient Akakdian myths such as story of Astra-Hasis, are just remnants of much older texts. Later on, they become part of story of Noe and his Ark (which is based on the Akkadian story and Utnapishtim). Myths and legends. Mostly... verbal. As a lot of writing, knowledge - was probably lost during that time. All was left was the "legends and myths" at the end. You also have underwater old structures all around the planet, for example close to Japan, but also plenty other places if you read about it. So, definitely something has happened during the last ice age, as the date of about 12K years ago is poping out quite often here and there in various myths, but also professional literature. And in a way, we actually know what has happened (or may have) - from the astronomy. Most likely some kind of meteor strikes, not just one, but multiple, small/large impacts on the ice polar caps too, lasting many years. At the end, quite large catastrophe, that most likely destroyed civilizations at that time, destroyed any possible coastal town/cities (whoever they were). And at some point the process was fast, especially after hitting the existing ice caps and melting of water (and more). I would suggest to start with something like the basic research: "Paleolitic Extinction and the Taurid Complex", by W.M. Napier, from Cardiff Centre for Astrobiology, Cardiff University, 2 North Road, Cardiff CF10 3DY, from Feb 2010 (Monthly notices of the Royal Astronomical Society: Mon.Not.R.Astron.Soc.405,1901-1906(2010)). Quotes from the above reasearch: "Intersection with the debris of a large (50-100km) short-period comet during the Upper Paleolithic, provides a satisfactory explanation for the catastrophe of celestian origin which has been postulated to have occured around 12900 BP, and which presaged a return to ice age conditions of duration of about 1300 yr. The Taurid Complex appears to be the debris of this erswhile comet..." "The sudden onset of the Younger Dryas cooling 12900 yr ago was marked by intense wildfires over North America, major distruption of human culture, and the rapid extinction of 35 genera of Noth American mammals (Faith & Surovell 2009). A thin lcarbon-rich black layer of this age has been identified at many sites across North America (Haynes 2008), coincident in age with the Younger Dryas Boundary. Recently, several geochemical markers at this layer have been presented which seem to indicate that a major extraterrestial event was involved in these events (Firestone et al.2007; Firestone 2009)." And then it list the markers such as: nondiamonds, soot, microspherules and magnetic grains (giving description of the research and further academic references for each of those). But to be honest, plenty of other researches too, even from sources not related to astronomy. But the above would be a good starting point. Edit: Added more quotes from the research, from Cardiff University. Plus some grammar/spelling check.

The problem is not only the additional volume of water melting into the ocean, the heating of the oceans will cause the water to expand, further raising the surface level. The melting of the Arctic and Antarctic ice sheets will also eliminate their reflection of sunlight and expose dark waters that will instead absorb sunlight and convert it to heat, further warming the oceans and again raising sea levels. Increased sea levels also means increased tides and storm surges, which dramatically increases erosion. Hotter ocean mean more frequent and powerful storms, again with higher storm surges. I was raised in Bermuda, which lies in the North Atlantic Ocean about 600 miles of the Coast of North Carolina. Growing up there we learned about the five glacial and interglacial periods that have successively inundated and revealed the archipelago, allowing coral colonies to form and then destroying them and eroding them to sand, then forming limestone. Currently Bermuda is comprised of 9 majors islands and more than 100 islets that together have a total landmass of about 22 square miles. However, during the peak of a glacial period the entire summit of the Bermuda Rose is exposed revealing a single island of 200 square miles (plus Argus and Challenger Banks. Over the past 150 million years since Bermuda formed this has happened five times if I recall correctly, and the islands are of course presently shrinking. Bermuda is comprised of a relatively soft limestone cap sitting on top of an extinct submarine volcano. Limestone can be broken by hand, so you can imagine the damage wreaked by a powerful hurricane or winter gale. The first Bermuda, a volcanic island, stood at 1,000 feet above sea level. Currently, the highest hill stands at just over 200 feet. The climate there has grown noticeably warmer in my life time; winter temperatures as low as 44°F (6°C) were not uncommon when I was growing up, but over the past 14 years I do not think the temperature has dropped below 56°F (13°C), and I recall meteorologists reporting that the harsh winter of 2010-2011 was the first normal winter for 20 years. For those of us raised on Oceanic Islands, we know the Ocean and we observe the weather like an unpredictable and potentially dangerous alcoholic neighbour. I am betting long term, I moved to the continent.

We take medicine and drugs to overcome diseases and infections without giving a chance to body to fight itself by immune system. Although we swim we just use boats and flights to travel over sea.

Great Episode! I enjoy how Dr. Tyson and Chuck Nice bring concepts forward by nerding while not geeking. I think a lot about climate and soo much of the conversations have a real issue seperating fear of change from fear of climate. As a species I really believe we can do better with so much but I feel if someone wants to project anger and have no solutions better forums for frustration management might be a business model more people should look into. I find the estimate of rise of the oceans difficult in perception. Just rough math from your left elbow comment would mean 30.5 million km cubed would need to be added to the entire surface of the planet if raw math of volume holds. Hard to conceptualize but I do wonder greatly how thorough the computational models and ai tasking are with parameters.
