The geologic evidence of the high point in those natural cycles 120,000 years ago indicates that sea level rose, with no human causes, to a level 25 feet higher than it is, today. It is amusing to see people posting about "natural cycles" as a reason to not believe that sea level will rise. The research is published across two papers both featured in the journal Nature. "These new ways of observing the glacier allow us to understand that it's not just how much melting is happening, but how and where it is happening that matters in these very warm parts of Antarctica," Cornell University researcher and Icefin team member Britney Schmid said. This means these features may become the primary trigger for ice shelf collapse at Thwaites. The melting of ice in these terraces, cracks, and crevasses may become major factors in the loss of ice from Thwaites in the future, especially as major rifts progress across the ice shelf. In these staircase-shaped regions, called terraces, the ice of Thwaites is also melting rapidly. While a layer of cold fresh water below the bottom of the ice shelf and above the underlying warm ocean is slowing the rate at which the flat parts of the ice shelf melt, the team was shocked to discover that melting across the bottom of the ice shelf has created a staircase-like formation. Antarctica's Denman Glacier is sinking into the world's deepest canyon Greenland's glaciers are melting 100 times faster than estimated Wow! Iceberg larger than London breaks off Antarctica (photos) Cracks and crevasses weren't the only area of the shelf experiencing rapid melting, however. This can result in the widening of these crevasses, causing large rifts in the ice shelf. Melting in cracks and crevasses is potentially dangerous because as water funnels through them, heat and salt can be transferred into the ice. ![]() The new data provides a clearer picture of the changes taking place under Thwaites, revealing that ice in cracks across the glacier is melting quickly. The factors causing this retreat are, however, poorly understood. The grounding zone of this glacier has retreated by 8.7 miles (14 kilometers) since the 1990s, making Thwaites one of the fastest-changing glaciers in Antarctica. Icefin is particularly useful for investigating the grounding zone of Thwaites, the point at which the glacier touches the ocean floor, which has previously been almost impossible to study. To assess the Thwaites Glacier's vulnerability to collapse, the two groups observed ice melt rates and the properties of the glacier and its surrounding ocean by lowering instruments via a 1,925 feet (587 meters) deep hole drilled into the ice and by launching a torpedo-shaped underwater robot called Icefin under the glacier. This could, in turn, destabilize neighboring glaciers, potentially increasing future sea levels by almost an additional 10 feet (3 meters). The collapse of Thwaites would cause seawater levels to rise by around 2 feet (65 centimeters). One part of the glacier juts out into the ocean and holds back the rest of the ice-mass that lies on bedrock, thus preventing it from slipping from the land to the sea.īecause the Thwaites Glacier slopes down towards the sea, it is particularly susceptible to climate and ocean temperature changes that could lead to rapid and irreversible ice loss. Join us this week while we give you a run down of some of these.Thwaites Glacier is located in West Antarctica and covers 74,000 square miles (192,000 square kilometers). However, the deeper into the water you go, the more complex and crazier the conspiracies get such as: Concrete People of Collaguasi, Bank of Souls, and JFK SHOT HIMSELF.basically there's levels to this conspiracy shit! Some are hilarious, most are bullshit, but all are super interesting. Basic/more well known conspiracies like UFO's, Mandela Effect, and Pizzagate are placed at the top of the iceberg. A picture that has been floating around the worlds of reddit and 4chan the past few years is a full length picture of an iceberg with multiple conspiracies placed within. One of the pillars of this show is our take on conspiracy theories. ![]()
