Climate Change in Antarctica

The article "Warm water rapidly melting Antarctica from below due to climate change"  by the science correspondent Josh Gabsatiss, explains how climate change creates tremendous warm underwater that melts Antarctica's ice sheets, resulting in a rise of sea level which is estimated to highly threaten humankind due to possible natural disasters. It is also crucial to find the quantity of melted water expected to increase in order to be able to map the retreat of grounding lines, since the ice shelves connected to the bedrock underneath may collapse. Dr Hannes Konrad claims that the retreatment occurs across the unstable ice sheet because of the fundamental ocean melt. The author mentions studies on how some regions with different variations in sea level increase rate, such as West Antarctica, can enlarge the global sea level  (3meters) solely by themselves. Scientists noted that underwater melting also extremely impacts huge glaciers, where the grounding lines can not be visually illustrated, therefore they are measured with the effective help of satellites. 

In my opinion, underwater melting in Antarctica is not a simple task to deal with and it is only one cause of global sea level increase among many others. Realistically. it is now an impossible issue to prevent because it is already occuring, but it should highly be taken in consideration and studied in order to find solutions of its impact reductions, since it directly targets everyone and every region globally, which could potentially threaten hundreads of millions humans. The technology put in place to examine grounding lines is a step forward to understand future solutions to the problematic, but does not absolutely solve it.

After reading your summary, I decided to chose your article because I found the topic interesting insofar as, typically, one wouldn't associate the melting of glaciers to warm water from beneath. In fact, the article mentioned an interesting fact that the melting of an underwater glacier the size of greater London had melted throughout the space of 5 years. I think that its rather alarming to think of all the natural disasters that could occur in the future given our current lifestyles. The article you chose is really interesting also in the sense that as the author mentions rising sea levels are an important threat to mankind. Also interesting is when you mention that the accumulated sea level rise could in the near future rise approximately 3 meters. Finally, I'll end off by mentioning that like you stated stopping the rise in sea levels is practically impossible and water levels will inevitably continue to rise however I would recommend maybe finding a way to slower sea level rise since stopping it entirely is impossible. Indeed, my suggestion would be to impose something that is already present, that being a protocol that would diminish carbon emissions.
