On World Frog Day (March 20), attention is drawn to India’s amphibians, where citizen science and conservation initiatives are helping address rising threats like climate change and habitat loss.
Ecological Importance of Frogs
Act as link between aquatic and terrestrial ecosystems
Control insect populations (pests)
Serve as food for higher vertebrates
Help convert: → Insect biomass → Vertebrate biomass
Global & Indian Status
As per International Union for Conservation of Nature:
Amphibians = most threatened vertebrates
37 species extinct globally
India:
450+ amphibian species
~25% threatened
~20% data deficient
Major Threats to Frogs
1. Disease (Historical Driver)
Chytridiomycosis caused by:
Batrachochytrium dendrobatidis
Batrachochytrium salamandrivorans
Affects frog skin (critical for respiration & ion balance)
Impact: → Affected >60% amphibians globally
2. Climate Change (Current Major Driver)
Impacts 39% species
Causes:
Mismatch in monsoon timing
Breeding failures due to: Early rains + prolonged dry spells
3. Habitat Loss
Impacts 37% species
Includes: Wetland loss, Deforestation, and Urbanisation.
[2024] Consider the following: 1. Butterflies 2. Fish 3. Frogs How many of the above have poisonous species among them? (a) Only one (b) Only two (c) All three (d) None
A study published in Ecology Letters (March 2026) by University of British Columbia and collaborators shows ringed seals risk predation to access diverse food in the Arctic.
Key Species Involved
Ringed seal: Primary prey species in Arctic marine ecosystems
Polar bear: Main predator dependent on sea ice for hunting
Study Area & Method
Location: Eastern Hudson Bay (Arctic region)
Tracked: 26 seals and 39 polar bears
Tools: GPS tracking, Dive data analysis and Sea-ice mapping + fish diversity models
Core Findings
1. Food vs Fear Trade-off
Seals avoid high-risk zones (areas with many polar bears)
BUT:
Enter these zones if food diversity is high
Stay longer underwater (long dives) even in danger zones
2. “Landscape of Fear” Concept
Animals modify behavior based on predator presence
Seals:
Move quickly through risky areas
Adjust diving patterns depending on threat level
3. Portfolio Effect (Very Important)
Seals prefer diverse prey instead of a single food source
Similar to financial diversification:
Reduces risk of food scarcity in changing environments
4. Behavioral Adaptations
Possible ability to: Detect predators (e.g., listening for polar bears on ice)
Limitation: Hard to scientifically capture such micro-behaviors
5. Climate Change Impact
Melting sea ice leads to:
Altered predator-prey interactions
Increased bear density in smaller ice areas
Entry of new predators like killer whales
Key Ecological Insight
Wildlife survival depends on dual factors:
Food availability
Predation risk

Wireless charging using laser.
Operates at room temperature.
Energy stored lasts much longer than charging time (very high efficiency).
Unique Property
Charging speed increases with size
Opposite to classical batteries.
Known as quantum advantage in charging.
Potential Applications
Ultra-fast charging of electric vehicles.
Wireless energy transfer over long distances.
High-efficiency next-generation energy storage systems.
Current Limitations

PYQ Relevance[UPSC 2025] What is Carbon Capture, Utilization and Storage (CCUS)? What is the potential role of CCUS in tackling climate change?Linkage: The PYQ covers climate change mitigation and environmental technology (GS 3), especially emission reduction strategies like CCUS. The article applies this through India’s CCUS-focused carbon credit policy, highlighting tension with agriculture-based carbon markets.
Mentor’s Comment
India’s Carbon Capture, Utilization, and Storage (CCUS) initiative aims to reduce greenhouse gas emissions to meet 2070 net-zero targets, focusing on high-emitting industrial sectors. The Union Budget 2026-27 announced a ₹20,000 crore scheme to scale up CCUS deployment, specifically targeting power, steel, cement, refineries, and chemical industries. The Budget 2026 announcement highlights the tension between industrial decarbonisation via CCUS and nature-based carbon markets involving agriculture. This raises issues of policy clarity, sectoral prioritisation, and climate governance design.
What is the core objective of India’s carbon credit plan?
Industrial Decarbonisation Focus: Targets sectors like power, steel, cement, refineries, and chemicals where emissions are concentrated and difficult to eliminate.
CCUS Deployment: Ensures capture of CO₂ from industrial flue gases and its utilization or storage underground.
Technology-led Transition: Supports R&D roadmap released by Department of Science and Technology (Dec 2025).
Budgetary Commitment: ₹20,000 crore over five years for large-scale CCUS deployment.
Why is agriculture excluded from CCUS strategy?
Emission Characteristics: Agricultural emissions (methane, nitrous oxide) are diffuse and biologically mediated.
Technological Limitation: CCUS is suited for point-source emissions, not dispersed sources like farms.
Policy Segregation: Clear distinction between CCUS (industrial) and Carbon Dioxide Removal (CDR) via soil, biochar, agroforestry.
Role of Agriculture: Positioned under carbon sequestration pathways, not industrial capture.
What is causing confusion around ‘farmer carbon credits’?
Terminology Overlap: Use of “carbon credit programme” creates perception of inclusivity across sectors.
Parallel Narratives: Media and discourse suggest farmers can directly earn credits under Budget allocation.
Existing Voluntary Markets: Agriculture and forestry projects already generate credits for domestic and global buyers.
Policy Communication Gap: Lack of clear distinction between regulated compliance markets and voluntary carbon markets.
What are the implications of prioritising CCUS over agriculture?
Industrial Competitiveness: Supports decarbonisation of sectors contributing ~25% of India’s emissions.
Net-Zero Alignment: Essential for achieving India’s climate commitments.
Missed Rural Opportunity: Delays monetisation of agriculture’s carbon sequestration potential.
Fiscal Prioritisation: Directs public funds toward capital-intensive technologies instead of nature-based solutions.
Can agriculture-based carbon markets emerge as a parallel opportunity?
Soil Carbon Sequestration: Enhances carbon storage through regenerative practices.
Agroforestry Potential: Integrates trees into farming systems to generate carbon credits.
Private Sector Initiatives: Pilot programmes compensate farmers for sustainable practices.
Policy Requirement: Needs separate funding, institutional frameworks, and certification mechanisms.
What policy approach is required to resolve the ambiguity?
Dedicated Agricultural Policy: Establishes structured carbon farming programme with incentives.
Market Development: Creates trusted domestic carbon market for agriculture credits.
Communication Clarity: Ensures alignment between policy design and public narrative.
Conclusion
India’s carbon credit framework reflects a dual transition challenge: industrial decarbonisation through CCUS and agricultural transformation through carbon sequestration. Policy clarity, sector-specific instruments, and institutional coherence are essential to avoid misaligned expectations and unlock full climate and economic potential.

Forecasters, including NOAA Climate Prediction Center, warn of a possible El Niño in 2026, with chances it could intensify into a “super El Niño”, potentially pushing global temperatures to new highs.
What is El Niño?
A warm phase of the El Niño–Southern Oscillation (ENSO)
Occurs when Pacific Ocean surface waters become warmer than normal
What is a “Super El Niño”?
When sea surface temperature rises ≥ 2°C above average
Much stronger than normal El Niño
Rare events: Last major one: 2015–16
Current Situation
Present phase: La Niña (cool phase) is ending
Forecast: ~62% chance of El Niño by mid-2026 and ~15% chance of super El Niño
How El Niño Works
Warm water shifts toward eastern Pacific
Weakens trade winds
Alters global weather systems
[2011] La Niña is suspected to have caused recent floods in Australia. How is La Niña different from El Niño? 1. La Niña is characterized by unusually cold ocean temperature in the equatorial Indian Ocean whereas El Niño is characterized by unusually warm ocean temperature in the equatorial Pacific Ocean. 2. El Niño has an adverse effect on the southwest monsoon of India, but La Niña has no effect on monsoon climate. Select the correct answer: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2
