Many frightening facts have been published about climate change, but increasingly shocking pieces of data keep coming to light again and again. Recently, an international study has shown that along with the Greenland and Antarctic ice caps, glaciers are also losing a tremendous quantity of ice.
In the course of the study, the variations in the thickness of the ice in more than 19 thousand glaciers around the world were modelled. The measurements shed light on annual variations, while satellite data also allowed the total ice loss over several years or decades to be determined.
The study has shown that
The glaciers in the Alps, in Caucasus and in New Zealand have also lost a great deal of water, but due to their relatively smaller surface areas, they played less of a role in the rising level of the oceans.
In total, the glaciers of the world lose 335 billion tonnes of water per year, which contributes 25-30 percent to the current global rise of sea levels.
Climate change is causing increasingly horrifying disasters around the world. In April 2018, a video went viral on the Internet in which several massive blocks of ice could be seen breaking off the Breiðamerkurjökull Glacier in Southeast Iceland.
Based on data from NASA, Business Insider have produced a video about the consequences that would result if all the ice on Earth melted. According to the space agency’s calculations, sea level would rise by as much as 65.8 m if all the glaciers and polar ice caps melted.
In the last days of April 2019, after days of heavy rain, rivers flooded and reservoirs overflowed in eastern Canada. The situation was so severe that several thousand people in the region had to leave their homes.
Saint-Louis is a coastal city of almost 300 thousand people in Senegal. It is situated by the mouth of the most important river of West Africa, the Senegal, and its old town is on a peninsula between the ocean and the river. Its highest point is less than four metres above sea level, so the city is particularly exposed to the impacts of climate change.
Melting glaciers, devastating storms and floods – these are just a few of the disasters attributable to climate change, along with the rise of global sea levels. It is a startling piece of news that global sea levels may rise by a great deal more than previously estimated, by as much as 1.32 metres by 2100, which may have grave consequences.
