The Arctic ice sheet: rapid decline and implications for the global ecosystem
ArabiaWeather - The Arctic is one of the most important environmental regions on Earth, as it plays a crucial role in regulating the global climate. The Arctic ice cover has been rapidly declining in recent decades, raising concerns about the environmental, economic and social repercussions that may result from this rapid change.
The decline of the ice cover and climate change is the reason
Scientific data indicate that the Arctic ice cover is retreating at an alarming rate. This decline is mainly due to rising temperatures caused by climate change. According to the Intergovernmental Panel on Climate Change (IPCC), the average temperature of the Arctic has risen two to three times compared to the global average, leading to rapid melting of sea ice and rivers. Icy.
Implications of the decline of the Arctic ice cover on the ecosystem
Many Arctic terrestrial species depend on sea ice for survival. Polar bears, for example, need ice to hunt seals. As the ice retreats, it becomes difficult for these animals to obtain food, leading to an alarming decline in their numbers. The retreat of ice also affects the entire marine system. Sea ice plays an important role in reflecting sunlight, and thus in regulating ocean temperature. As the ice retreats, the oceans absorb more heat, leading to changes in ocean currents and in turn affecting marine life and associated ecosystems.
For their part, meteorological specialists at the Arab Weather Center said that the melting of ice in the Arctic contributes to a rise in sea levels, which threatens coastal areas around the world with drowning and affects millions of people. As changes in the Arctic directly affect the global climate. Changing sea currents and polar airflow can lead to more extreme weather, including severe storms and prolonged periods of drought or heavy rain.
