Rapid Melting of Turkiye’s Mount Cilo Glaciers

Why in the News ?

Mountain glaciers on Cilo Mountain, the second-largest glacier zone in southeastern Turkey, are experiencing rapid melting of glaciers due to climate change impact. Experts warn that nearly 50% of ice cover has disappeared over the past four decades, intensifying heatwaves and drought. This melting of alpine glaciers is part of a broader trend affecting water resources and contributing to sea level rise globally, necessitating improved water resource management strategies and attention to groundwater availability.

Glacier Retreat Observed on Mount Cilo:

● Cilo Mountain, at 4,135 meters, lies in Hakkari province near the Iraq border.

● It holds Turkiye’s second-largest glacier system, after Mount Ararat.

● Kemal Ozdemir, a local mountain guide, noted that visible glacier chunks now float downstream, showing accelerated melt and increased glacial meltwater.

● Areas once permanently ice-capped are now bare rock and grass, reflecting rapid warming and changes in local microclimates.

● Waterfalls are flowing more intensely, signalling rapid glacial melt feeding streams and potentially forming meltwater lakes in the alpine watershed.

Impact of Climate Change in Turkiye

● Human-induced global warming has intensified heatwaves and droughts across southeastern Turkey.

● The country recently recorded a historic high of 50.5°C.

● The melting rate has exceeded scientific predictions, alarming researchers involved in world glacier monitoring efforts and glacier database maintenance.

● Geographer Onur Satir from Yuzuncu Yil University states that nearly half the glacier mass has vanished in 40 years, highlighting the need for an updated glacier inventory.

● Melting glaciers disrupt water availability, threaten biodiversity, and risk natural disasters like floods, impacting overall ecosystem integrity and alpine springs.

About Glaciers and Climate Change :

● Glaciers are critical freshwater reservoirs, regulating river systems and climate, influencing groundwater recharge and surface runoff patterns in the alpine watershed.

● Their retreat is a key climate indicator, monitored by global bodies like the UN and IPCC using advanced techniques such as environmental isotopes and carbon isotopes analysis.

● According to the UN, many world glaciers may not survive this century, a stark contrast to conditions during the Little Ice Age.

● Melting glaciers contribute to sea level rise and alter weather patterns, affecting hydrogeological processes and potentially leading to coastal erosion.

● Glacier monitoring and preservation efforts need international cooperation and strong climate policies, including international outreach programs.

● The melting of mountain glaciers is not just a local issue but part of the broader climate crisis affecting alpine communities worldwide, from the Andes Mountains to Glacier National Park.

● The process of iceberg calving in tidewater glaciers is accelerating, further contributing to ice mass loss and sea level rise.
