Practice questions
Q1Match List I with List II and select the correct answer using the code given below: List I (Climate-policy concept) A. Mitigation B. Adaptation C. Loss and damage D. Maladaptation List II (Description) 1. Reduces vulnerability to actual or expected impacts 2. Addresses harms not fully avoidable through mitigation or adaptation 3. Reduces emissions or enhances removals 4. Reduces short-term risk but increases long-term vulnerability
Mitigation reduces emissions or enhances removals; adaptation reduces vulnerability; loss and damage concerns residual harms; and maladaptation lowers short-term risk while increasing long-term vulnerability. The correct matching is A-3, B-1, C-2, D-4.
Q2With reference to the National Action Plan on Climate Change, consider the following statements: 1. It was launched on 30 June 2008. 2. It originally listed eight national missions. 3. All its missions are exclusively mitigation missions. Which of the statements given above are correct? Select the correct answer using the code given below.
Statements 1 and 2 are correct. The plan was launched on 30 June 2008 with eight national missions. Statement 3 is incorrect because the missions include mitigation, adaptation-capacity and knowledge functions; they are not exclusively mitigation missions.
Q3Match List I with List II and select the correct answer using the code given below: List I (Gas) A. Carbon dioxide B. Methane C. Nitrous oxide D. Fluorinated gases List II (Associated source) 1. Refrigeration and air-conditioning 2. Nitrogen fertilisers and manure 3. Fossil-fuel burning and cement 4. Livestock and rice fields
Carbon dioxide is associated with fossil-fuel burning and cement; methane with livestock and rice fields; nitrous oxide with nitrogen fertilisers and manure; and fluorinated gases with refrigeration and air-conditioning. Thus the matching is A-3, B-4, C-2, D-1.
Q4Consider the following statements: 1. A high share of non-fossil sources in installed power capacity necessarily means an equally high share in actual electricity generation. 2. Solar and wind generation varies with time and season. Which one of the following is correct?
Statement 1 is incorrect and Statement 2 is correct. Installed capacity and actual generation are different indicators; the variable output of solar and wind can make their generation share lower than their installed-capacity share.
Q5Arrange the following climate-policy instruments or plans in chronological order, beginning with the earliest: 1. Paris Agreement 2. National Action Plan on Climate Change 3. United Nations Framework Convention on Climate Change 4. Kyoto Protocol Select the correct answer using the code given below.
The United Nations Framework Convention on Climate Change dates to 1992, the Kyoto Protocol to 1997, the National Action Plan on Climate Change to 2008, and the Paris Agreement to 2015. Therefore, the chronological order is 3-4-2-1.

6Arrange the following stages of the greenhouse mechanism in the correct sequence: 1. The warmed surface emits long-wave infrared radiation. 2. Solar radiation reaches Earth mainly as visible and short-wave energy. 3. Greenhouse gases absorb specific infrared wavelengths. 4. Part of the heat is re-emitted back towards the surface. Select the correct answer using the code given below.
7With reference to climate change and ecology, consider the following statements: 1. A mismatch in the timing shifts of pollinators and plants can disturb food webs. 2. Drainage can turn a wetland from a carbon store into an emissions source. 3. Fixed protected-area boundaries always contain the future ranges of species affected by warming. Which of the statements given above are correct? Select the correct answer using the code given below.
8With reference to evidence and indicators of climate change, consider the following statements: 1. The ocean stores most of the excess heat in the climate system. 2. Relative sea level at a coast can be affected by local land subsidence or uplift. 3. All Himalayan glaciers respond identically to warming. Which of the statements given above are correct? Select the correct answer using the code given below.
9With reference to greenhouse gases and related agents, consider the following statements: 1. Water vapour is mainly a feedback in current warming rather than the principal direct human forcing. 2. Black carbon can warm the climate by absorbing radiation and darkening snow or ice. 3. Fluorinated gases necessarily have low warming potential because they occur in small quantities. Which of the statements given above are correct? Select the correct answer using the code given below.
