It’s no secret that the climate of our planet has lately got warmer. This, of course, cannot happen without causing some serious changes in the environment. Some of the effects of global warming have already become visible, while others are lurking from the shadow. Researchers have decided to explore what our planet might suffer, and discovered some worrying possibilities. The ice layers at the poles is quickly shrinking, which might lead to a sudden increase in the sea level.
The most stable ice sheet in Antarctica wasn’t actually so stable
A big surface of the ice layers present both at the North and the South Pole has already started melting, contributing to a certain increase of the sea level. However, this has happened gradually and hasn’t had such a big impact on the environment yet. Researchers had good news as well, as they regarded a big surface of ice, the East Antarctic Ice Sheet, as incredibly stable and not affected by the higher temperatures.
Unfortunately, the situation might not be as good as they thought. They continued monitoring the ice layers, and discovered that this region wasn’t really protected from global warming. After the analysis of the East Antarctic Ice Sheet, they discovered certain portions of it which were sensitive to any changes in the climate.
Many coastal cities are threatened by the melting of the ice layers
This icy sheet holds the biggest quantity of water ever contained by any ice layers. If it starts melting, the global sea level will increase by 53 meters. This is precisely as bad as it sounds, as many cities from the coast are doomed if this happens.
The analyses revealed the history of the East Antarctic Ice Sheet. This region wasn’t stable at all and, instead, it gradually switched from an expanding to a shrinking state. In other words, it kept contributing to the sea level increase for a long period of time. If global temperatures keep growing, all ice layers of Antarctica are threatened.
