During the United Nations Conference on Environmental Resources, which was held in New York between March 22-24, the Secretary-General of the international organization, Antonio Guterres, issued the following warning messages:
Melting glaciers may lead to the shallowing of major rivers in South Asia, such as the Ganges, Indus and Brahmaputra. Rising sea levels caused by melting, coupled with salt water intrusion, will destroy most of the large deltas of these rivers. Rivers and glaciers serve as the planet’s largest reservoir of fresh water, and their retreat is life-threatening.

The environmental expert, Dr. Domit Kamel, head of the Global Environment Party (an association for environmental awareness based in Beirut), enumerated for “Sky News Arabia” the reasons for the melting of glaciers, and how the matter reached the current danger:
Global warming changed the pattern of coldness in the layers of the atmosphere, which caused the phenomenon known as “global warming” that affects the poles, mountains and glaciers. An increase in the Earth’s temperature by 1.5 degrees has negative repercussions, such as the melting of rivers and glaciers, as well as affecting forests and all living things. Melting snow is a double crisis, in that it triggers one change and then causes other changes, such as sea level rise. The melting of large quantities of snow on the surface of the planet, whether in the poles or highlands, such as the Himalayas, is likely to increase in light of the sharp climate changes. These comprehensive negative effects prompted global organizations to move and work to reduce the rise in temperature. Globally, there is no unified strategy to confront these changes, in addition to the continuation of the major industrialized countries in their activities without monitoring, and the consumption of huge quantities of fossil fuels.
The “Science” magazine, through a study published recently, highlighted the acceleration of the rate of losses due to climate change, including the loss of 26 percent of the total ice mass, noting that smaller rivers will be the first to be affected.
The number of glaciers in the world reaches 215,000 rivers, half of which, especially the small ones, are at risk of disappearing by the end of the current century if the Earth’s temperature is limited to 1.5 degrees Celsius above pre-industrial levels.
But if the climate warms by an additional 4 degrees Celsius, the worst-case scenario will occur, as larger glaciers such as those in Alaska will be affected by increasing amounts.
