  • Strengthening the roots of an agri-carbon market

    Why in the News?

    In India, current carbon credit projects by private organisations should be reviewed to ensure they are fair and work effectively.

    What are the current carbon credit projects? 

    • Collaborative Initiatives: NABARD, ICAR, and State Universities have listed five agricultural carbon credit projects in the Verra registry to promote sustainable agriculture.
    • Carbon Farming Projects: Over 50 projects targeting 1.6 million hectares aim to generate 4.7 million carbon credits annually, but none are registered, leaving farmers without financial benefits.

    Note: Verra is a carbon credit registry that manages the Verified Carbon Standard (VCS), ensuring high-quality carbon credit projects and facilitating transparent trading of carbon credits.

    What are the key challenges facing agricultural carbon markets?

    • Lack of Communication and Training: A significant portion of farmers (45%) reported inadequate communication regarding carbon farming practices, and over 60% lacked training in new techniques. This gap in knowledge can hinder the effective implementation of sustainable practices necessary for generating carbon credits.
    • Exclusion of Marginalized Communities: Many existing carbon farming projects have not adequately included smallholders and marginalized communities, with women representing only 4% of participants. This lack of inclusivity limits the socioeconomic benefits that carbon markets could provide to a broader segment of the farming population.
    • Financial Incentives: A notable 28% of farmers discontinued sustainable practices by the second year due to insufficient financial incentives. The absence of timely payments for carbon credits further discourages participation and undermines project sustainability.
    • Unregistered Projects: Despite over 50 agricultural carbon farming projects being listed in the Verra registry, none have been officially registered, meaning no carbon credits have been issued and farmers have not received any financial compensation.
    • Quality Assurance: Ensuring that projects deliver reliable environmental benefits is crucial. If projects fail to produce credible carbon credits, it may lead to a loss of confidence among buyers, which would ultimately deprive farmers of income and discourage sustainable practices.

    How can farmers be incentivized to participate in carbon markets?

    • Higher Prices for Inclusive Projects: Offering premium prices for carbon credits from projects that actively include smallholders and marginalized communities can encourage broader participation and ensure equitable benefits.
    • Effective Communication and Training Programs: Establishing robust communication channels and providing regular training on sustainable agricultural practices will empower farmers to adopt new techniques confidently.
    • Guaranteed Timely Payments: Implementing a system that ensures farmers receive prompt payments for their carbon credits will enhance trust in the market and encourage ongoing participation in sustainable practices.
    • Collaboration with Research Institutions: Partnering with national and international research organizations can help identify suitable regions for carbon farming, ensuring that interventions are effective and do not compromise food security.
    • Bundling Small Farmers into Cooperatives: Creating Farmer Producer Organizations (FPOs) can help reduce transaction costs, improve bargaining power, and facilitate easier access to carbon markets for smallholder farmers.

    What role do technological advancements play in enhancing agri-carbon markets?

    • Improved Measurement Techniques: Advances in digital technologies such as remote sensing, satellite imagery, drones, and sensors will enhance the monitoring, reporting, and verification (MRV) processes essential for assessing soil carbon levels and GHG emissions accurately.
    • Data Accessibility: The increasing availability of technology will allow farmers to access real-time data on their farming practices, enabling them to make informed decisions that align with sustainable methods required for carbon credit generation.
    • Enhanced Project Implementation: Technology can streamline project management by facilitating better communication between stakeholders, tracking progress, and ensuring compliance with additionality and permanence criteria necessary for successful carbon credit projects.
    • Scalability of Projects: Digital tools can help scale successful carbon farming initiatives by providing frameworks that can be replicated across different regions, thus expanding the reach of agricultural carbon markets in India.

    Way forward: 

    • Strengthen Inclusivity and Farmer Incentives: Promote inclusive projects that actively engage smallholders and marginalized communities by offering premium prices for carbon credits, ensuring timely payments, and bundling farmers into cooperatives for better market access.
    • Leverage Technology for Efficiency: Utilize advanced digital tools like remote sensing and real-time data systems to improve monitoring, reporting, and verification (MRV) processes, enhance project scalability, and ensure effective implementation of carbon credit initiatives.

  • Arctic Tundra is emitting more Carbon than it absorbs: NOAA

    Why in the News?

    • The Arctic Tundra, a frozen treeless biome, has traditionally served as a carbon sink, storing vast amounts of carbon for thousands of years.
      • However, recent changes in this ecosystem are turning it into a source of greenhouse gases (GHGs), primarily carbon dioxide (CO2) and methane (CH4) according to National Oceanic and Atmospheric Administration (NOAA).

    What is Arctic Tundra?

    • Arctic Tundra is cold, treeless biome located in the northernmost regions of Earth, primarily within the Arctic Circle.
    • Climate:
      • Experiences long, harsh winters and short, cool summers.
      • Temperatures range from -28°C in winter to 3°C in summer.
      • Ground is permanently frozen, restricting plant root growth and shaping the ecosystem.
      • Experiences 24-hour daylight in summer and long polar nights in winter.
    • Biodiversity and Vegetation:
      • Limited to low-growing vegetation like mosses, lichens, grasses, and small shrubs, adapted to short growing seasons.
      • Hosts animals like Arctic foxes, polar bears, caribou, and migratory birds, though overall biodiversity is low.
    • Adaptations:
      • Animals: Thick fur and fat layers in species like polar bears to survive extreme cold.
      • Plants: Shallow roots for quick nutrient absorption during short summers.

    How does the Arctic Tundra store Carbon?

    • The Arctic tundra stores carbon primarily through a process where plants absorb carbon dioxide (CO2) from the atmosphere via photosynthesis.
      • This carbon gets trapped in the soil and organic matter (plants and animals) that accumulate over time.
    • The cold Arctic climate slows the decomposition of plant and animal remains, meaning that organic materials, including carbon, remain locked in the permafrost.
      • This permafrost acts as a natural storage system, preventing CO2 from being released back into the atmosphere.
    • Scientists estimate that the Arctic tundra holds about 1.6 trillion metric tonnes of carbon, which is roughly double the amount of carbon in the Earth’s atmosphere.

    Why is the Arctic Tundra emitting more carbon than absorbing it?

    • Rising temperatures in the Arctic are causing the permafrost to thaw at an accelerated rate.
      • When permafrost thaws, microbes in the soil become active, breaking down the organic material trapped in the frozen ground, which results in the release of carbon dioxide (CO2) and methane (CH4), two potent greenhouse gases.
      • The Arctic has been warming at a rate four times faster than the global average.
      • 2024 was the second-warmest year on record for the region, contributing significantly to the thawing of the permafrost.
    • Wildfires in the Arctic have become more frequent and intense, further accelerating the thawing of permafrost. Wildfire smoke also contributes to the release of greenhouse gases.
    • Between 2001 and 2020, the combination of rising temperatures and increased wildfires led to the Arctic tundra releasing more carbon than it absorbed, marking a significant shift in its role from a carbon sink to a carbon emitter.

  • First Ice-Free day in the Arctic could come by 2030: Study

    Why in the News?

    A recent study suggests that the Arctic Ocean may experience its first ice-free day—where sea ice falls below one million square kilometres—by 2030, or even sooner.

    Key Highlights of the Study

    • First Ice-Free Day Prediction: The study predicts that the Arctic Ocean could experience its first ice-free day (less than one million square kilometres of sea ice) by 2030, or even sooner, depending on climatic conditions.
    • Simulations and Models:
      • 11 different climate models were used to run 366 simulations from 2023 to 2100 to assess the future of Arctic sea ice.
      • Most simulations predict the ice-free day within 7 to 20 years, with some models suggesting it could happen as early as September 2027.
    • Conditions for Ice-Free Day: The occurrence of an ice-free day will depend on a combination of unusually warm seasons and stormy weather, which accelerates the melting of the sea ice.
    • Impact on Sea Ice: Once the first ice-free day occurs, it could be followed by an ice-free period lasting between 11 to 53 days, potentially leading to the first ice-free month.

    Why does it matter?

    • Climate Change Acceleration: The loss of sea ice will amplify the Albedo effect, causing the Arctic region to absorb more sunlight and heat, which will accelerate global warming and trigger extreme weather events in mid-latitudes.
    • Rising Sea Levels: The loss of Arctic ice contributes to sea level rise, with potential long-term impacts on coastal populations and ecosystems, particularly if the Greenland ice sheet melts completely, which could raise sea levels by 6 meters.
    • Ecosystem and Species Impact: The melting of sea ice will threaten species that rely on the ice for habitat, such as polar bears, walruses, and reindeer, disrupting the Arctic food chain.
    • Human and Infrastructure Threats: Arctic communities and their infrastructure are at risk as the region warms at four times the global average, threatening the livelihoods of people living in these areas.

    Back2Basics: Albedo Effect

    arctic albedo

    • It refers to the measure of how much sunlight is reflected by a surface.
    • It is expressed as a percentage; a surface with a high albedo reflects more sunlight, while a surface with a low albedo absorbs more.
    • Light-colored surfaces like ice and snow have high albedo, reflecting most of the sunlight, whereas dark surfaces like oceans and forests have low albedo, absorbing more heat.

    Q)  Describe the major outcomes of the 26th session of the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). What are India’s commitments at this conference? (UPSC CSE 2021)

    Mentor’s Comment:  UPSC Mains have focused on India’s changing policy towards climate change (2022) and COP26 (2021).

    The recent UN Climate Change Conference (COP29) held in Baku, Azerbaijan, concluded with significant yet contentious outcomes, particularly regarding the New Collective Quantified Goal (NCQG) for climate finance. This editorial reflects on the implications of the NCQG and the broader context of climate negotiations.

    This editorial content can be used to present the significance of ‘Climate finance for developping countries’ and the challenges associated at Global stage.

    _

    Let’s learn!

    Why in the News?

    COP29 dubbed the “Finance COP,” was expected to deliver an ambitious outcome on the NCQG (New Collective Quantified Goal on Climate Finance). However, it fell short by neglecting equitable burden-sharing and climate justice, overlooking the financial needs of the Global South.

    Why do the Developing countries need Finance for climate change? 

    • Upfront Costs of Clean Technologies: Renewable energy technologies often have high upfront costs, which require government support to make them affordable to consumers, especially in developing countries.
    • Long-term Benefits but High Initial Investment: While renewable technologies have lower long-term operational and fuel costs, the high initial investment remains a significant barrier.
    • Financial Gaps and Urgency: Developing countries need urgent upscaling of finance to meet transformational goals. The pressure on government resources is compounded by the need for fiscal prioritization toward development activities.
    • Debt Issues and Risk: High debt burdens in developing countries prevent them from accessing affordable capital, making it difficult to incentivize private investment in green technologies.
    • High Cost of Capital: Developing countries face much higher lending rates, limiting their ability to access financial markets at favourable rates for climate action.
    • International Support Needed: Finance from developed countries, particularly in the form of public grants instead of loans, is essential to support the transition to green energy in developing nations.

    What are the roles of the NCQG (New Collective Quantified Goal on Climate Finance)?

    • Origins and Rationale: The NCQG was designed to address the shortcomings of previous climate finance pledges, including the $100 billion annual commitment made at Cancun in 2010. The NCQG aims to establish clearer, more accountable climate finance goals.
      • NCQG aims to establish a new financial target post-2025 to support developing countries, succeeding the $100 billion annual commitment from developed nations.
    • Addressing Climate Finance Gaps: NCQG seeks to bridge climate finance gaps by ensuring both the quantity and quality of financial instruments meet developing nations’ needs.
      • By setting a collective goal, NCQG promotes trust and cooperation among nations to effectively implement the Paris Agreement.
    • Catalyzing Private Investment: NCQG encourages private sector investment by signalling stability and commitment to climate finance.
    • Supporting Climate Resilience: The goal help developing countries adapt to climate impacts and transition to low-carbon economies with necessary funding.
    • Upholding Principles of Equity: NCQG is grounded in Common but Differentiated Responsibilities (CBDR), ensuring tailored support for developing countries based on their specific needs and capacities.

    What are the challenges?

    • Financial Needs of Developing Countries: The UNFCCC’s Second Needs Determination Report estimated that $5 trillion to $7 trillion would be required by 2030 to meet the needs of 98 developing countries. Developing nations have requested $1.3 trillion annually by 2030.
    • Disappointing Outcome at COP29: Developed countries agreed to a $300 billion annual commitment by 2035, which is seen as insufficient compared to the needs of the developing world. This amount does not represent a significant shift in financial flows and falls short of transformative action.
    • Lack of Commitment to Climate Justice: The NCQG falls short in terms of equitable burden-sharing, failing to adequately recognize the financial needs of the global south and climate justice.

    Way forward: 

    • Increase Financial Commitments: Developed countries must significantly enhance their financial commitments, moving beyond the $300 billion annually agreed at COP29, and align with the $1.3 trillion requested by developing nations to meet urgent climate goals.
    • Ensure Equitable Burden-Sharing: Future climate finance discussions must prioritize climate justice, adhering to the principles of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC), ensuring that developed countries take on a larger share of the financial burden.
    • Focus on Grants over Loans: Developed countries should provide more finance in the form of public grants rather than loans, addressing the debt burdens of developing countries and enabling them to invest in green technologies without further exacerbating fiscal constraints.

  • COP-29 discussions flagging, no progress made on issues critical to developing countries: India

    Why in the News?

    The first week of the COP29 summit in Baku ended without major progress, as stark divisions between developed and developing nations hindered agreements on climate finance, trade measures, and equitable climate responsibilities.

    What is a COP meeting? 

    • Establishment and Early Meetings: The COP was established in 1995 following the adoption of the UNFCCC in 1992 at the Earth Summit in Rio de Janeiro. The first COP (COP1) took place in Berlin, Germany, where parties began to negotiate binding commitments to reduce greenhouse gas emissions.
      • This initial meeting set the stage for subsequent negotiations and agreements, including the Kyoto Protocol in 1997, which established legally binding targets for developed countries to reduce emissions.
    • Evolving Focus and Agreements: Over the years, COP meetings have evolved to address not only mitigation strategies but also adaptation, finance, and technology transfer to developing countries.
      • The landmark Paris Agreement was adopted at COP21 in 2015, establishing a global framework for climate action with commitments from all countries to limit global warming to well below 2 degrees Celsius.

    What is the status of climate finance commitments from developed countries?

    • Unmet Financial Pledges: Developed countries have failed to fulfill the $100 billion annual climate finance goal set in 2009, leading to growing frustration among developing nations.
    • Loans Dominate Finance: Nearly 70% of climate finance provided so far is in the form of loans, creating a debt burden for vulnerable economies.
    • Demand for $1.3 Trillion Annually: The G-77/China bloc has called for a significant increase in climate finance to $1.3 trillion annually, with a focus on grants and concessional funding instead of debt-inducing mechanisms.
    • Equity in Climate Finance: Developing nations demand accountability and emphasize that climate finance should address both mitigation and adaptation needs equitably.

    How will the Mitigation Work Programme (MWP) support developing countries?

    • Capacity Building: The MWP aims to enhance the capabilities of developing countries to implement Nationally Determined Contributions (NDCs) effectively.
    • Technology Transfer: A robust technology implementation program with dedicated financial backing is proposed to ensure equitable access to climate technologies.
    • Adaptation Finance: The MWP includes provisions for scaling up financial resources to assist countries in adapting to climate impacts, especially for those most vulnerable.
    • Equity in Responsibility: The MWP aligns with the principle of “common but differentiated responsibilities” (CBDR), ensuring that mitigation efforts consider historical emissions and current capacities.

    What measures will be taken to address unilateral trade actions impacting developing nations? (Way forward)

    • Criticism of CBAM: Developing nations, including India and Bolivia, criticized the European Union’s Carbon Border Adjustment Mechanism (CBAM), which they view as a discriminatory trade barrier violating equity principles.
    • Call for Equity: Developing nations argue that CBAM shifts the burden of climate action to economies with minimal historical emissions, impacting industrial growth and development.
    • Opposition to External Regulations: India emphasized that mitigation measures must align with NDCs and national sovereignty, opposing attempts to impose external climate regulations.
    • Collaboration Against Trade Barriers: The BASIC bloc, AOSIS, and the Arab Group are working together to resist measures like CBAM and push for trade policies that consider the needs of the Global South.
    • Reforms in Multilateral Financial Systems: Countries like South Africa advocate for multilateral reforms to ensure fairer financial systems and debt relief for vulnerable economies.

  • Article 6.4 of the Carbon Market

    Article 6.4 of the Carbon Market

    Why in the News?

    • At the COP29 climate summit in Baku, Azerbaijan, the adoption of Article 6.4 of the Paris Agreement has paved the way for global carbon trading under UN supervision.
      • This new development allows UN member countries to trade carbon credits globally.

    What is Article 6.4?

    • Article 6.4 of the Paris Agreement establishes a global carbon market to facilitate carbon credit trading between countries.
      • It is part of Article 6, which outlines mechanisms for international cooperation in achieving net-zero emissions.
    • Objective: Enable countries to offset their emissions by investing in emission reduction projects in other countries.
    • It establishes a global carbon market overseen by a UNFCCC Supervisory Body.
      • This body would develop rules, monitors credit issuance, and ensures compliance with international standards.
    • It allows countries to generate and trade Emission Reduction Credits (ERCs), which represent reductions in CO₂ or equivalent greenhouse gases.
      • Credits are earned from approved climate projects and can be traded globally.
    • Through subsections like Article 6.2, countries can use ITMOs (Internationally Transferred Mitigation Outcomes) to meet their NDCs, which are tradeable units representing emissions reductions.

    Significance of Article 6.4

    • Cost-Effective Climate Action: By enabling global carbon markets, Article 6.4 could save an estimated $250 billion annually in implementing climate plans, providing a cost-efficient path to emission reductions.
    • Support for NDCs: The mechanism helps countries meet their NDC targets under the Paris Agreement, allowing more flexibility and incentivizing investments in green projects worldwide.
    • Economic Growth and Climate Mitigation: Carbon markets foster investments in clean energy, create jobs in climate-focused sectors, and link economic growth with climate action.
    • Encourages Sustainable Development: Article 6.4 incentivizes sustainable projects in developing countries, promoting green technology transfer and supporting local economies.

    Types of Carbon Credit Projects under Article 6.4

    • Emission Reduction Projects
      • Energy Efficiency Improvements: Reducing energy consumption (e.g., efficient lighting, better insulation).
      • Renewable Energy: Replacing fossil fuels with solar, wind, or hydroelectric power.
    • Emission Removal Projects
      • Reforestation and Afforestation: Increasing forest cover to absorb CO₂.
      • Soil Carbon Sequestration: Storing carbon in soil through agricultural practices.
    • Carbon Storage Projects
      • Geological Storage: Storing CO₂ in deep underground formations.
      • Biochar Production: Locking carbon in biochar, enhancing soil fertility.
    • Technological Carbon Capture and Storage (CCS)
      • Direct Air Capture: Capturing CO₂ from the air and storing it underground or using it industrially.
      • Ocean-Based Solutions: Enhancing ocean CO₂ absorption, such as through algae cultivation.

    Issues with Article 6.4

    • Carbon Offsetting Criticisms: Critics argue that offsetting doesn’t reduce global emissions but shifts responsibility, allowing countries to continue emitting while claiming neutrality.
    • Carbon Accounting Challenges: Unreliable carbon accounting can lead to “phantom credits,” where emissions reductions are overstated or inaccurately recorded, failing to match actual reductions.
    • Greenwashing Risks: Some countries and companies may use carbon credits as a form of greenwashing, claiming carbon neutrality while continuing to pollute.
    • Equity and Climate Justice Concerns: Developing nations, which contribute less to global emissions, are the most vulnerable to climate impacts.
    • Potential for Reversal Risks: Projects that store carbon in natural reservoirs risk releasing it back into the atmosphere. Some standards allow projects to end monitoring if reversal risk is considered “negligible,” which remains undefined and problematic.

  • Glacial Lakes rise as glaciers retreat

    Why in the News?

    Since 1977, the South Lhonak Lake, a glacial lake in Sikkim has expanded significantly, growing from 17 hectares to 167 hectares by 2023.

    Formation of Glacial Lakes:

    • When a glacier melts and retreats, the hollow left behind often fills with water, creating a glacial lake.
    • The rocky moraine at the glacier’s end can act as a natural dam, holding the water to form the lake.
    • Glacial lakes act as hydrological buffers, regulating water flow from melting ice, which can sometimes pose challenges to downstream communities.
    • Glacial lakes often have a vivid blue color, similar to swimming pools, due to the scattering of light by fine rock particles (rock flour) in the water.
    • There are several types of glacial lakes, each formed by specific processes and glacier dynamics:
      • Moraine-Dammed Lakes: Formed when moraine debris piles up at the end of a glacier and traps meltwater behind it. These are common and pose risks of outburst flooding.
      • Kettle Lakes: This was created when a chunk of glacier ice is buried in the moraine and eventually melts, leaving a depression filled with water.
      • Cirque Lakes: Formed in circular basins (cirques) carved by glaciers at high elevations. These lakes are often small and located at the glacier’s original head.
      • Pro-glacial Lakes: Situated in front of the glacier, between the ice and the moraine dam. These lakes are sometimes formed when the glacier’s snout melts and deposits water in the valley.
      • Tarn Lakes: Formed in depressions left behind in the cirques or basins after the glacier has completely melted.

    Major Glacial Lakes in India

    India’s Himalayan region is home to numerous glacial lakes, each with unique characteristics:

    • Gurudongmar Lake (Sikkim): One of the highest lakes in the world at 5,430 meters above sea level, fed by glacial melt and known for its religious significance.
    • Chandra Taal (Himachal Pradesh): A stunning crescent-shaped lake in the Lahaul-Spiti region at 4,300 meters. It is surrounded by snow-capped mountains and fed by glacier melt.
    • Samiti Lake (Sikkim): Located along the trek to Kanchenjunga and known for its clear blue waters and reflective quality.
    • Satopanth Tal (Uttarakhand): Found in the Garhwal Himalayas, this lake lies close to Satopanth Glacier and is considered sacred by locals.
    • South Lhonak Lake (Sikkim): A growing lake fed by three glaciers, expanding rapidly due to climate change and posing risks of glacial lake outburst floods.

  • Why the goal to arrest global temperature rise to 1.5°C is unrealistic?

    Why in the News?

    Over nine years ago, the world promised to cut emissions significantly, but it hasn’t succeeded. As a result, the goal of keeping global warming below 1.5 degrees is now out of reach.

    Is the 1.5°C Target Still Achievable?

    • Rising Emissions: Global emissions are still increasing, with 2023 seeing record levels. Despite clean energy advancements, emissions reductions have been insufficient to meet the pace required for the 1.5°C target.
    • Potential for Emission Peaking: The UNEP Emissions Gap Report suggests that emissions could peak by 2023 or 2024 if significant additional measures are taken, but global actions remain inconsistent and often insufficient.
    • Need for Accelerated Action: For the 1.5°C goal, global emissions need to drop by at least 43% by 2030 from 2019 levels.
      • Current projections indicate only a 2.6% reduction by 2030, far short of the required cuts.
    • Technological and Financial Challenges: Achieving the 1.5°C target hinges on rapid technological deployment, energy transition, and substantial financing for climate action. However, these remain constrained by a lack of coordination and resources.

    Implications of Exceeding the 1.5°C Limit

    • Increased Frequency of Extreme Events: Exceeding 1.5°C would lead to more frequent and severe extreme weather events, such as heatwaves, droughts, wildfires, and intense storms.
    • Impacts on Ecosystems and Biodiversity: Many species and ecosystems are sensitive to small temperature changes; coral reefs, for instance, face near-total collapse beyond 1.5°C warming.
    • Threats to Human Health and Livelihoods: Exceeding 1.5°C could lead to more heat-related illnesses, loss of productivity, water scarcity, and risks to food security, disproportionately affecting vulnerable populations.
    • Feedback Loops: Warming beyond 1.5°C may activate feedback loops (e.g., Arctic ice melt, permafrost thawing), which could lead to irreversible changes and make further warming difficult to control.

    Should We Reconsider the Focus on the 1.5°C Target?

    • Adaptation vs. Mitigation: Given the increasing difficulty of limiting warming to 1.5°C, some argue for a shift in focus towards adaptation strategies to manage the unavoidable impacts of higher temperatures.
    • Realigning Expectations: While the 1.5°C target was critical to rally global climate action, a shift towards realistic, achievable goals may better support gradual but sustained progress, especially if mitigation pathways fall short.
    • Moving Towards a ‘Just Transition’: With a likely overshoot of the 1.5°C target, there is a greater need to ensure that climate adaptation and resilience measures do not disproportionately burden low-income countries and communities.
    • Science-Based Overshoot Scenarios: The IPCC and other scientific bodies continue to assess overshoot scenarios (e.g., temporarily exceeding 1.5°C and then returning below it later) to guide global climate strategies. However, returning to a lower temperature after an overshoot requires substantial and sustained negative emissions, which are currently unfeasible at scale.

    Way forward: 

    • Prioritize Scalable Emissions Reductions and Resilient Adaptation: Accelerate global transition to renewable energy, improve energy efficiency, and reduce methane and other non-CO₂ emissions. Simultaneously, invest in adaptation measures to help vulnerable communities manage the impacts of warming beyond 1.5°C.
    • Strengthen Climate Finance and International Cooperation: Mobilize substantial climate funding for developing nations to support both mitigation and adaptation efforts. Enhance cross-border technology sharing and policy alignment to enable collective, equitable climate action.

  • The La Nina and North India’s pollution

    Why in the News?

    The delayed onset of La Niña and the late retreat of the monsoon have diminished hopes that Delhi’s residents might enjoy improved air quality this winter compared to previous years.

    What is Triple-dip La- Nina?

    Triple-dip La Niña refers to the rare occurrence of La Niña persisting for three consecutive years, causing prolonged cooler ocean temperatures in the Pacific and influencing global weather patterns, including stronger monsoons.

    How has the triple-dip La Niña phenomenon influenced air quality in North India?

    • No dispersion of pollutants: The delayed onset of La Niña has led to stagnant air and calm winds, preventing the dispersion of pollutants. In previous winters, La Niña helped improve air quality with stronger winds and atmospheric circulation.
    • Trapped air pollutants: The slower monsoon retreat resulted in extended periods of high humidity, reduced atmospheric mixing, and trapped pollutants near the surface, contributing to deteriorated air quality.

    What meteorological factors contributed to the observed anomalies in air quality?

    • Monsoon Retreat and Humidity: The delayed retreat of the monsoon contributes to prolonged periods of high humidity and calm winds. These conditions reduce atmospheric mixing, trapping pollutants near the surface and leading to elevated levels of PM2.5 and PM10.
    • Stagnant Winds: The absence of La Niña conditions results in stagnant surface winds, which hinder the dispersion of pollutants. This stagnation is particularly problematic given the regional emissions from stubble burning and other sources.
    • Stubble Burning: With prevailing north-north-westerly winds, stubble burning in Punjab and Haryana could significantly worsen Delhi’s air quality if it occurs at even half the intensity seen in previous years.

    What implications does this have for future climate and air quality management strategies?

    • Need for Broader Focus: There is a growing recognition that air quality management must shift from a localized emission-centric approach to one that considers larger meteorological patterns and regional airsheds.
    • Policy Recommendations: Policymakers should prioritize mitigating PM2.5 emissions over PM10, as PM2.5 poses greater health risks.
    • Integration of Climate Factors: Future air quality strategies should integrate climate change considerations, recognizing that local emissions are only part of the equation.

    Way forward:

    • Adopt Regional Airshed Management: Shift from a localized approach to a broader airshed strategy, accounting for meteorological patterns and regional pollution sources to improve air quality management.
    • Prioritize PM2.5 Mitigation and Climate Integration: Focus on reducing PM2.5 emissions, which pose higher health risks, and incorporate climate change factors into long-term air quality policies for comprehensive solutions.
  • How global warming affect forecasting?

    Why in the News?

    The record warming of 2023-2024 is offering a clearer view of the impacts of global warming. The range of extreme events experienced globally has spanned from deadly heatwaves to devastating cyclones and floods, as well as droughts and wildfires.

    Impact of Warming on Predictability:

    • Increased Variability: The record warming of 2023-2024 highlights the unpredictability of climate systems under global warming, complicating forecasts for natural phenomena like El Niño, monsoons, and hurricanes.
    • Natural Variability: Warming may extend the timescale of natural decadal variability, making it harder to distinguish between short-term fluctuations and long-term trends in climate behaviour.
    • Model Limitations: Despite advances, climate models are imperfect in capturing changes in dominant climate modes due to warming, leading to inconsistencies in predicting events like monsoon trends.

    Types of Climate Models to forecast the weather: 

    1. General Circulation Models (GCMs): These models simulate the physics of the climate system by representing the interactions between the atmosphere, oceans, land, and ice. They divide the Earth into a three-dimensional grid and calculate climate variables like temperature and humidity in each grid cell.
    2. Earth System Models (ESMs): An advanced subset of GCMs that includes biogeochemical cycles, allowing them to simulate interactions between climate and ecological processes, such as carbon and nitrogen cycles.
    3. Regional Climate Models (RCMs): These focus on smaller geographic areas to provide more detailed climate projections by using outputs from GCMs as inputs for localized simulations.
    4. Integrated Assessment Models (IAMs): These combine climate science with socioeconomic factors to analyze how human activities influence climate change and to project future emissions scenarios.

    Challenges in Forecasting Extreme Weather:

    • Inconsistent Predictions: Predictions for extreme weather events in 2023, such as the monsoon and hurricane seasons, were less accurate, revealing the limitations of current models and observational networks.
    • Unforeseen Factors: Unanticipated contributions, like the impact of the Hunga Tonga volcano or wildfire-induced CO2 emissions, exacerbated warming in ways models failed to predict, illustrating the unpredictability of new factors.
    • Censorship Concerns: The rapid response required from social media platforms to act on content flagged as misleading within 36 hours created concerns about censorship and freedom of expression.

    Future of Weather Prediction Models:

    • Need for Model Improvements: There is ongoing work to refine models and incorporate the latest technologies, including AI and machine learning, to improve weather prediction accuracy at hyperlocal scales.
    • Natural Modes and Uncertainty: The predictability of natural modes (El Niño, La Niña, IOD) may decrease with relentless warming, making future climate forecasts increasingly uncertain.
    • Short-Term Focus: A shift toward short-term predictions (up to a decade or two) may offer more reliable projections due to the inherent difficulty in predicting long-term scenarios under continuous global warming.

    Way forward: 

    • Enhanced Climate Models: Invest in improving climate models with cutting-edge technologies like AI, machine learning, and advanced sensors to increase the accuracy of short-term forecasts and better capture the impact of natural variability under warming.
    • Localized Early Warning Systems: Develop robust, hyperlocal early warning systems to better prepare for extreme weather events, focusing on disaster management and reducing vulnerabilities in high-risk communities.
  • A climate crisis agenda remains urgent

    Why in the News?

    Although voters voiced concerns about the climate crisis, it was overlooked during the Lok Sabha election campaign.

    2023 Climate Targets of Indian Government

    • Renewable Energy Goals: India aims to achieve 500 GW of non-fossil fuel-based energy capacity by 2030, with a target for 50% of its total energy needs to come from renewable sources.
    • Emissions Goals: The updated Nationally Determined Contributions (NDC) set a goal to reduce emissions intensity of GDP by 45% compared to 2005 levels by 2030.
    • Carbon Sink Targets: India plans to create an additional carbon sink of 2.5–3 billion metric tons of CO2 equivalent through enhanced forest and tree cover by 2030.
    • Net Zero Commitment: Aiming for net zero emissions by 2070, India has committed to significant reductions in projected emissions, including a pledge to reduce one billion tonnes of emissions from now until 2030.
      • As of late 2023, India has already achieved a cumulative electric power capacity from non-fossil fuel sources at approximately 43.81%, ahead of its initial targets.

    Why is addressing the climate crisis an urgent priority for policymakers and the global community?

    • The Paris Agreement includes a commitment for developed countries to mobilize $100 billion per year by 2020 to support climate action in developing countries. This target was extended until 2025, with new financial goals.
      • The next five years are crucial for India’s climate action to meet its ambitious 2030 targets, as the Roadmap for 2025 Climate Change Funds are about to end.
    • India’s heavy dependence on coal, with clean energy contributing only 22% of the electricity mix, underscores the need for an urgent transition.
    • Immediate attention is required to manage heat stress, improve air quality, handle waste, and enhance energy efficiency.

    What specific actions or policies can be implemented?

    • Enhanced Carbon Markets: Launching the ‘India Carbon Market’ in 2026 aims to help achieve Nationally Determined Contributions (NDCs) and could become the world’s largest emissions trading system by 2030.
    • Mitigating Pollutants: Focus on reducing CO2 and short-lived superpollutants like methane, black carbon, and hydrofluorocarbons, which have significant short-term warming effects.
      • Integrating specific treaties into the Paris Agreement, similar to the Montreal Protocol, with a new treaty targeting methane reductions by 2030 would be helpful.
    • Financial Incentives: Developing financial mechanisms and nuanced carbon trading approaches to encourage faster climate action and effective pollutant management.

    What challenges or barriers exist in the implementation of a comprehensive climate crisis agenda?

    • Governance and Coordination: Need for a Constitutional nodal authority to ensure coordinated climate action across various government levels and stakeholders.
    • Economic and Social Factors: Rising temperatures and associated crises like unemployment and high living costs contribute to public disengagement from climate issues.
    • Political and Voter Engagement: The 2024 Lok Sabha election’s lack of focus on climate issues highlights the challenge of integrating climate action into mainstream political agendas and addressing voter concerns.

    Way forward: 

    • Create a Constitutional Nodal Authority: Form a central body with the authority to oversee, coordinate, and enforce climate policies across various government levels, ensuring effective and unified action.
    • Prioritize Climate Issues in Political Platforms: Make climate action a central theme in political campaigns and public discussions to boost awareness, engagement, and support for climate policies and initiatives.
