STATION scientific Base Esperanza, Antarctica, argentina, Thursday, February 6, at 12, temperature 18,3 degrees. It was the hottest day in the area since 1961, announced the national meteorological service, a sad record for the ice cap to the south. The previous record was 17.5 degrees, measured on the 24 march 2015. At the base of Marambio, another scientific station, the temperature reached 14.1 degrees, a record for the month of February since 1971. The previous record was 13.8 degrees, touched on February 24, 2013.
These temperatures are “certainly shocking but unfortunately not surprising, given that the Antarctic is warming up along with the rest of our planet,” commented Frida Bengtsson , a specialist of the marine environment of Greenpeace. After a decade-long record, which was concluded with the 2019 second-warmest year ever recorded on the planet, the 2020 starts about the same with January the hottest month ever recorded. As a direct consequence of the increase in temperatures due to human activity, the two ice caps of the world, in Antarctica and Greenland, have already lost an average of 430 billion tonnes per year since 2006, raising therefore the level of the sea. And the future of coastal regions and their millions of inhabitants depends on the mass of ice that covers the west Antarctic.
According to climate experts (Ipcc), the sea level rose 15 cm in the twentieth century. The pace is accelerating, and sea level will continue to rise for centuries to come. In Antarctica, scientists are observing the glacier and Thwaites, one of the most massifs of the western part of the continent. It has almost the size of Great Britain, its collapse could raise sea level by 65 cm, warns the International Thwaites Glacier Collaboration (ITGC), which is currently on site to try to understand how quickly this could happen. “Over the past 30 years, the amount of ice that melts from the glacier and Thwaites, and from the glaciers neighbours has almost doubled”, say the scientists. The glacier alone is responsible for 4% of the rise in global sea level, adds to the collaboration. Argentina is present in the 114 years in the Antarctic, where he has several scientific bases. Is a signatory to the Antarctic Treaty, which entered into force in June 1961, which forbids any kind of militarisation of the continent, reserves it “for activities peaceful.”
