Context:
Recently, A study published in the journal ‘Environment Research’ finds that the tropical glaciers in East Africa are shrinking at a fast pace due to Climatic Factors.
East Africa is losing its Tropical Glaciers: Key Findings of Study
- In East Africa, total glacierization is estimated to be only 1.36 km2.
Deglaciation: Deglaciation refers to the retreat or melting of ice sheets and glaciers.
Effects of Deglaciation:
- Shrinking of Glaciers results in a decrease in the ice mass.
- A global rise in sea levels.
|
- The area of Tropical glaciers was observed to have shrunk with 0.069 sq km on Mount Kenya, 0.38 sq km in the Rwenzori Range(Uganda/DRC), and 0.98 sq km in Kilimanjaro (Tanzania).
- The glacier area in these three regions of East Africa is retained below 10% compared to the first observation around 1900.
- The overall area has declined by more than half of its early 21st-century extent.
- Being mainly controlled by high-altitude hygric seasonality, These glaciers are precious indicators of tropical climate variability and climate change.
- Other High Mountain Ranges like the Southern American Andes & Indonesian Sudirman Range that contain tropical Glaciers have one thing in common: They are situated near the Equator & influenced by the Intertropical Convergence Zone (ITCZ).
Important Tropical Glaciers in East Africa
- In Rwenzori Ranges (Uganda/DRC): Mount Stanley, Mount Speke and Mount Baker.
- In Kilimanjaro (Tanzania): Northern Ice Field, Southern Ice Field, Kersten Glacier.
- Kenya: Northey and Darwin glaciers, Lewis Glacier.
- Other Important Glaciers in African Continent: Credner Glacier and Furtwangler Glacier
- Mount Kilimanjaro:
-
- It is located in Tanzania, East Africa, is a dormant volcano and
- Highest peak on the African continent with its summit towering at 5,895 meters above sea level
- Comprises three distinct volcanic cones—Kibo, Mawenzi, and Shira—Kibo.
