Cavities are not something you want to find either in your teeth or in an Antarctic glacier. A cavity has been developing in the Thwaites Glacier in West Antarctica becoming 1,000 feet tall and roughly two-thirds the size of Manhattan based on information provided by a study published on Thursday coming from a NASA Jet Propulsion Laboratory study. The rate at which the glacier melts can be sped up by this empty space resulting in the sea levels rising.
How fast is this glacier melting? What are the effects?
In 2017 the Thwaites Glacier was looked at by an investigation by the New York Times which estimated that it is the size of Florida. Furthermore, they also calculated how much ice is falling into the sea from it. According to NASA 4 percent of the total sea level increase comes from the shedding of this glacier.
Now 14 billion tons of ice from this glacier are in the sea as this is how much the cavity contained previously. The existence of this cavity proved researcher’s estimation of the melting speed wrong. It is happening way faster, and if it is for this glacier to melt completely, the sea level will raise more than two feet.
What is happening to the ice all over the world?
Last year 40 earth sciences agencies created a report in which they mentioned that Antarctica had lost so much ice over the last 25 years that three trillion tons of it are now water. The primary source was West Antarctica which made the sea levels rise by 7 and a half millimeters.
The sea level rises not only from the glaciers melting but also because of the climate change. As this keeps happening, coastal and wildlife communities are affected permanently. Millions of people will be forced to relocate as there are flooding risks for coastal communities and low-level land areas.
Karen and her husband live on a plot of land in British Columbia. They aim to grow and raise a significant part of their food by maintaining a vegetable garden, keeping a flock of backyard chickens and foraging. They are also currently planning a move to a small cabin they hand built. Karen’s academic background in nutrition made her care deeply about real food and seek ways to obtain it. Thus sprung Anna’s interest in backyard gardening, chicken and goat keeping, recycling and self-sufficiency.
