  • Places in News: Kariyachalli Island

    Why in the News?

    The Tamil Nadu government, with World Bank support, has launched a ₹50 crore restoration project for the sinking Kariyachalli Island.

    About Kariyachalli Island:

    • Overview: Kariyachalli Island is one of the 21 uninhabited islands in the Gulf of Mannar Marine National Park.
    • Geographic Location: It lies 4 km south of Sippikulam and 20 km northeast of Thoothukudi, between Rameswaram and Thoothukudi.
    • Made of Reef Sediments: The island is a low-lying landform made of reef debris, sand dunes, spits, and sandy plains.
    • Biodiversity Hotspot: Located in India’s coral reef zone, it supports 4,300+ marine species, including 132 coral types and the endangered dugong.
    • Ecological Importance: It has seagrass beds and coral reefs that provide food and shelter for marine life.
    • Natural Coastal Shield: Kariyachalli acts as a barrier against cyclones and tsunamis, helping protect the Tamil Nadu coast.
    • Historical Significance: It played a role in mitigating the 2004 Indian Ocean tsunami impact.

    Why is it sinking?

    • Rapid Land Loss: The island has shrunk by over 70%, from 20.85 ha in 1969 to under 6 ha in 2024.
    • High Tide Erosion: At high tide, only 3.14 ha remains, per an IIT Madras (2025) study.
    • Wave and Sediment Pressure: Wave action, sediment loss, and lack of natural shoreline defense are accelerating erosion.
    • Climate Change Impact: Rising sea levels and coral bleaching have weakened the island’s natural protection.
    • Seagrass Depletion: Loss of seagrass beds has reduced the island’s ability to hold sediments and resist erosion.
    • Extreme Weather Events: Frequent cyclones and storms are making the island more vulnerable.
    • Future Risk: If the current trend continues, Kariyachalli may vanish by 2036.
    [UPSC 2023] Which one of the following is the best example of repeated falls in sea level, giving rise to present-day extensive marshland?

    Options: (a) Bhitarkanika Mangroves (b) Marakkanam Salt Pans (c) Naupada Swamp (d) Rann of Kutch*

     

  • Climate Threat Emerging from Rising Evaporative Demand and Thirstwaves

    Why in the News?

    Scientists have coined a new term, “thirstwave”, to describe spikes in evaporative demand, where a warmer atmosphere draws more water from plants, soil, and trees.

    What is Evaporative Demand?

    • Definition: Evaporative demand is the measure of how much water the atmosphere can potentially absorb from land, plants, and water surfaces if there is unlimited water available. It tells us how “thirsty” the atmosphere is.
    • Nature of Measurement: It is not about how much water is actually lost but how much could be lost if water was fully available. It depends on weather conditions, not the amount of water in the soil.
    • Standard Metric: The most widely used metric to quantify this is Standardized Short-Crop Reference Evapotranspiration (ETos)—which assumes a 12 cm grass surface with unlimited water availability.
    • Impact of Global Warming: As global warming increases atmospheric heat, evaporative demand also rises, making the air more “thirsty”.

    What is a Thirstwave?

    • Origin: “Thirstwave” is a newly coined term (2025) by Meetpal Kukal and Mike Hobbins to describe three or more consecutive days of extreme evaporative demand.
    • Definition: A thirstwave is a period of sudden and intense increase in evaporative demand, caused by hot, dry, and sunny weather. It means the atmosphere becomes extremely “thirsty” and starts pulling water rapidly from soil, plants, and water bodies, even if they already have limited moisture.
    • Distinction from Heatwaves: Unlike heatwaves, thirstwaves account for multifactorial stress, combining temperature, humidity, wind, and solar input.
    • Thirstwave in India: There is no dedicated data yet on thirstwaves in India, but researchers are beginning to investigate, especially in South Asia’s climate-vulnerable zones.

    • Key Features:
      • Simplified Model: ETos simplifies evapotranspiration by assuming fixed vegetation properties and only variable weather conditions.
      • Indicators of Stress: An increase in ETos indicates higher temperatures, lower humidity, faster wind, and stronger solar radiation.
      • Effect on Soil and Crops: Rising evaporative demand leads to more rapid drying of soil and plants, even with ample irrigation.
      • Agricultural Relevance: This directly affects irrigation scheduling, crop productivity, and climate-resilient farming strategies.

  • Ocean Darkening: A New Ecological Crisis

    Why in the News?

    A new study from the University of Plymouth has revealed that over 21% of the global ocean has significantly darkened in the last two decades.

    What is Ocean Darkening?

    • Ocean darkening refers to the reduction in sunlight penetration into the ocean’s upper layers, known as the photic zone (up to 200 meters deep), where sunlight drives photosynthesis and supports marine biodiversity.
    • This process is measured using the diffuse attenuation coefficient (Kd 490), which tracks how quickly light diminishes as it passes through seawater.
    • The photic zone is essential for phytoplankton productivity, oxygen generation, marine food chains, and the regulation of global climate.

    Recent Report Citing Ocean Darkening:

    • A new study by researchers from the University of Plymouth, published in 2024, titled “Darkening of the Global Ocean”, revealed that 21% of the global ocean has significantly darkened from 2003 to 2022.
    • Key findings:
      • 9% of the ocean saw a drop of more than 50 meters in light penetration—equal to the area of Africa.
      • 2.6% experienced a loss exceeding 100 meters in photic depth.
    • Affected Region: The study found the Arctic, Antarctic, Gulf Stream, and North Sea among the worst affected regions.
    • Causes:
      • Algal blooms from nutrient runoff in coastal areas.
      • Warming seas, altered plankton dynamics, and changing ocean currents in open ocean zones.

    Implications of Ocean Darkening:

    • Ecosystem Disruption: Light-dependent species, such as Calanus copepods, are being pushed into shallower zones, increasing predation and competition.
    • Loss of Habitat: The shrinkage of the photic zone could be one of the largest marine habitat losses ever, affecting fish stocks and biodiversity.
    • Climate Feedback Loop: Reduced photosynthesis in oceans could weaken the ocean’s role in carbon sequestration and oxygen production, worsening climate change.
    • Threat to Global Fisheries: The contraction of productive zones affects fish populations, jeopardising fisheries and food security.
    • Scientific Concern: Researchers warn that this hidden crisis could fundamentally alter marine ecosystems if not urgently addressed.
    [UPSC 2025] With reference to the planet Earth, consider the following statements:

    I. Rain forests produce more oxygen than that produced by oceans. II. Marine phytoplankton and photosynthetic bacteria produce about 50% of the world’s oxygen. III. Well-oxygenated surface water contains several folds higher oxygen than that in atmospheric air.

  • What are Shared Socioeconomic Pathways (SSPs)?

    Why in the News?

    A new ETH Zurich study warns that under the Shared Socioeconomic Pathway (SSP) 5-8.5 scenario, warming could make cyclones more intense and hit unusual regions with greater damage.

    What are Shared Socioeconomic Pathways (SSPs)?

    • Definition: SSPs are 5 global scenarios that show how changes in society, economy, and technology might influence climate adaptation and mitigation.
    • Purpose: They complement Representative Concentration Pathways (RCPs) by adding socioeconomic context to climate models.
    • Development: Created in the late 2000s, published in 2016, and used in the IPCC 6th Assessment Report and CMIP6 models.
    • Function: SSPs assume no new climate policies, helping scientists explore how global trends affect emissions and climate action.
    • The Five Pathways:
      1. SSP1: Sustainable and equitable world
      2. SSP2: Continuation of current trends
      3. SSP3: Regional rivalry with high population growth
      4. SSP4: Unequal world with high disparities
      5. SSP5: Fossil-fuel-based rapid economic growth
    • Usage: SSPs are used with RCPs to explore how different futures could affect the 1.5°C or 2°C warming targets.
    • Significance: They help policymakers assess how societal choices impact climate risks, emissions, and the feasibility of global goals.

    About SSP5-8.5 and Cyclone Risks:

    • Scenario Summary: SSP5 shows rapid economic growth fuelled by fossil fuels.
    • Radiative Forcing: SSP5-8.5 implies 8.5 W/m² of energy, compared to about 2.7 W/m² today.
    • Climate Target Gap: To limit warming below 2°C, forcing must stay around 2.6 W/m².
