Climate Change — COP, Mitigation, Adaptation

Introduction

Climate change is the most consequential environmental challenge of the twenty-first century, and for a candidate preparing for the RPSC examination, understanding the institutional, legal, and policy frameworks that shape the global and national response is not optional—it is central. This subtopic, Climate change — COP, mitigation, adaptation, sits under the broader Environment syllabus and has consistently appeared in previous year question papers. From the available dataset, ten questions have been resolved, spanning the years 2016 to 2024, and covering three distinct thematic clusters: (1) the location and outcomes of specific Conference of the Parties (COP) summits, (2) the missions under India’s National Action Plan on Climate Change (NAPCC), and (3) the temperature goals of the Paris Agreement. This indicates that RPSC tests both factual recall (e.g., “Which COP was held in Sharm El-Sheikh?”) and conceptual understanding (e.g., “Which NAPCC mission focuses on sustainable agriculture?”). The level of difficulty is moderate: questions require precise knowledge of key institutions, events, and policy instruments, but rarely demand complex analytical reasoning. The subtopic was tested in the 2024 examination as well, reinforcing its continued relevance.

Why does this topic matter for RPSC? First, Rajasthan is one of India’s most climate‑vulnerable states—facing desertification, water scarcity, and extreme heat—making climate adaptation and mitigation issues directly relevant to state policy. Second, the Union government’s climate missions, such as the National Solar Mission and the National Mission on Sustainable Agriculture, have concrete implementation pathways in Rajasthan (e.g., solar parks in Bhadla, sustainable agriculture in arid zones). Third, international climate negotiations (COP summits) frequently make headlines, and RPSC expects candidates to be current.

In this chapter, you will learn:

• The foundational science of climate change, including the greenhouse effect and global warming.
• The architecture and chronology of the United Nations Framework Convention on Climate Change (UNFCCC) and its annual COP meetings.
• The Paris Agreement (2015) – its goals, mechanisms, and significance.
• The Kyoto Protocol and the distinction between binding and voluntary commitments.
• The National Action Plan on Climate Change (NAPCC) – its eight core missions, with special emphasis on those tested (Sustainable Agriculture, Solar, Habitat, Green India).
• The twin strategies of mitigation (reducing greenhouse gas emissions) and adaptation (adjusting to inevitable impacts).
• Key COP outcomes: Glasgow Climate Pact (COP26), the Loss and Damage Fund (COP27), and the Global Stocktake (COP28).
• Common traps, memory aids, and exam‑specific techniques.

By the end of these notes, you will be able to confidently answer any RPSC question on COPs, NAPCC missions, and the fundamental dichotomy of mitigation versus adaptation.

Core Concepts & Foundations

Before diving into negotiations and national plans, we must establish a clear conceptual vocabulary. Every term defined below will be used throughout the chapter. Assume you are starting from zero.

Climate Change: A long‑term shift in average weather patterns (temperature, precipitation, wind) that defines a region’s climate. Since the Industrial Revolution, human activities—primarily the burning of fossil fuels—have accelerated this change, leading to global warming.

Global Warming: The observed increase in Earth’s average surface temperature, largely due to the enhanced greenhouse effect caused by rising concentrations of greenhouse gases (GHGs). The term is often used interchangeably with climate change, but strictly, global warming is a driver, and climate change is the broader set of consequences.

Greenhouse Effect: A natural process where certain gases (CO₂, CH₄, N₂O, water vapour) trap heat in the atmosphere, keeping the planet warm enough for life. Human activities have intensified this effect, causing the “enhanced greenhouse effect.”

Greenhouse Gases (GHGs): Gases that absorb and emit infrared radiation. The main ones are carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases (F‑gases). CO₂ is the most abundant long‑lived GHG, primarily from fossil fuel combustion and deforestation.

Mitigation: Actions taken to reduce the sources of GHGs or enhance their sinks (e.g., forests, oceans). Examples: shifting to renewable energy, improving energy efficiency, afforestation, carbon capture and storage.

Adaptation: Adjustments in natural or human systems to actual or expected climatic stimuli, in order to moderate harm or exploit beneficial opportunities. Examples: building sea walls, developing drought‑resistant crops, early warning systems for heatwaves.

Climate Resilience: The capacity of a system (ecological, social, economic) to anticipate, absorb, accommodate, and recover from the effects of climate change while retaining its basic structure and function.

Vulnerability: The degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change. Vulnerability is a function of exposure, sensitivity, and adaptive capacity.

Conference of the Parties (COP): The supreme decision‑making body of the UNFCCC. It meets annually to review the implementation of the Convention and any related legal instruments, such as the Kyoto Protocol and the Paris Agreement.

Nationally Determined Contributions (NDCs): The climate action plans that each country submits under the Paris Agreement, outlining its targets for reducing emissions and adapting to climate change. NDCs are updated every five years (ratchet mechanism).

Loss and Damage: Refers to the impacts of climate change that go beyond what people can adapt to. It includes both economic losses (infrastructure, crops) and non‑economic losses (loss of biodiversity, cultural heritage). The establishment of a Loss and Damage Fund was a landmark outcome of COP27.

Global Stocktake: A process under the Paris Agreement that takes place every five years to assess collective progress toward the Agreement’s long‑term goals. The first global stocktake concluded at COP28 in Dubai (2023).

Net Zero: A state where the amount of GHGs emitted into the atmosphere equals the amount removed. The Paris Agreement calls for global net zero by mid‑century. Many countries have pledged net‑zero targets (e.g., India: 2070).

Why these definitions matter for RPSC: Every PYQ tested one or more of these concepts. For example, the Paris Agreement temperature goal (Q7) is directly about “well below 2°C” and “pursuing efforts to 1.5°C”. The COP location questions (Q1, Q3, Q5, Q8) test your knowledge of the UNFCCC’s annual meetings. The NAPCC questions (Q2, Q4, Q6) require familiarity with India’s domestic mitigation and adaptation framework.

First‑principles analogy: Think of the Earth as a greenhouse. The glass roof allows sunlight in but traps heat. Now imagine someone adds an extra layer of insulation that never lets heat escape—that’s the enhanced greenhouse effect. Mitigation is like removing the extra insulation; adaptation is like installing a fan and shade cloth inside the greenhouse to survive the heat. COP is the annual meeting where all the greenhouse owners debate what to do.
