    Coral Reefs in the Gulf of Eilat recover after a ‘Shutdown’

    World Mapping | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Gulf of Eilat

    Why in the News?

    Researchers have discovered a significant pause in coral reef growth in the Gulf of Eilat/Aqaba during the late Holocene period.

    Key Highlights of the Study:

    • The study identified a 4,400 – 1,000-year hiatus in coral growth, similar to events observed in Mexico, Brazil, and Australia.
    • Scientists attribute this temporary halt to a sea-level drop caused by tectonic activity and cooling events, which exposed coral reefs and disrupted their development.
    • Despite this, the reef recovered by recolonizing from deeper coral communities, showcasing its natural resilience.

    Coral Reefs in the Gulf of Eilat recover after a ‘Shutdown'

    About Gulf of Eilat

    • It is the only glacier in the Himalayas included in the Global Glacier Casualty List, a recognition of its critical status.
    • It plays a vital role in studying the cryosphere, a critical water resource supporting 240 million people in the Himalayan region.

    Retreat of Yala Glacier

    • Yala Glacier is projected to disappear by the 2040s, reflecting the growing threat to Himalayan glaciers.
    • It has retreated by 680 meters between 1974 and 2021, with a 36% reduction in area during this period.
    • Its elevation, which ranged between 5,170m and 5,750m in 2011, has significantly declined.
    • The glacier has lost so much mass that it no longer meets scientific standards for effective observation.
    • The Hindu Kush Himalayan cryosphere is warming twice as fast as the global average, leading to rapid glacial retreat.

    About the Global Glacier Casualty List

    • It was launched in 2024 by a consortium of institutions including Rice University, World Glacier Monitoring Service (WGMS), World Meteorological Organization (WMO), and UNESCO.
    • It documents endangered or vanished glaciers.
