With reference to methane, consider the following statements:1) Methane is approximately 80 times more potent than CO₂ as a greenhouse gas (GHG) over a 20-year period.2) Methane remains in the atmosphere for around 50 years, making it a long-lived climate pollutant.3) The energy sector is the largest anthropogenic source of methane emissions, followed by agriculture.4) Controlling methane emissions is crucial for improving air quality as methane contributes to the formation of ground-level ozone.Which of the statements given above are correct? 1 and 3 only 1 and 4 only 2 and 3 only 1, 3, and 4 only Relevance: According to recent studies, Methane (CH4) emissions are surging, threatening global climate targets set by the Paris Agreement.Explanation:Methane is approximately 80 times more potent than CO₂ as a GHG and has contributed to around 30% of global warming since the industrial revolution. (Hence, statement 1 is correct)However, it remains in the atmosphere for only about 7 to 12 years. Therefore, reducing methane emissions or enhancing its sinks can significantly impact climate change in the short term, providing valuable time to tackle the more complex challenge of reducing reliance on fossil fuels and associated CO₂ emissions. (Hence, statement 2 is not correct)Abating methane emissions and enhancing atmospheric removal can rapidly mitigate warming, turning this climate villain into a crucial ally in keeping global temperatures within safe limits. Controlling methane emissions is crucial for improving air quality as methane contributes to the formation of ground-level (tropospheric) ozone, a harmful air pollutant that affects respiratory health. (Hence, statement 4 is correct)Key sectors responsible for methane emissions include energy (especially oil, gas, and coal), agriculture (primarily livestock and rice cultivation), and waste management (landfills). The largest anthropogenic source is agriculture, accounting for about 25% of emissions, closely followed by the energy sector (coal, oil, natural gas, and biofuels). (Hence, statement 3 is not correct)Therefore, option (b) is the correct answer.Subject: Current Affairs | EnvironmentLevel of Difficulty: Medium | Factual 2 / 5 Q2. With reference to the Harappan Civilization, consider the following statements:1) It flourished around 2500 BCE along the Indus River. 2) It was the largest of the four ancient urban civilizations alongside Egypt, Mesopotamia, and China. 3) Its sites are spread over India, Pakistan, and Afghanistan.4) It is also classified as an iron-age civilization.How many of the above statements are correct? Only one Only two Only three All four Relevance: 20th September 2024, marked 100 years since the discovery of the Indus Valley Civilization, which was announced by archaeologist Sir John Marshall on 20th September 1924. Explanation:The Harappan Civilization, also known as the Indus Valley Civilization (IVC), flourished around 2500 BCE along the Indus River. (Hence, statement 1 is correct)It was the largest of the four ancient urban civilizations alongside Egypt, Mesopotamia, and China. (Hence, statement 2 is correct)This civilization spans over 2,000 sites across 1.5 million sq. km in India, Pakistan, and Afghanistan and is famous for its advanced urban planning and architecture. (Hence, statement 3 is correct)The IVC is classified as a Bronze-age civilization due to the discovery of numerous artefacts made from copper-based alloys. (Hence, statement 4 is not correct)Daya Ram Sahni first excavated Harappa in 1921-22, and Rakhal Das Banerji began excavating Mohenjo-daro in 1922. Sir John Marshall, DG of ASI, was responsible for the excavations that led to the discovery of Harappa and Mohenjo-Daro sites of IVC. Therefore, option (c) is the correct answer.Subject: Current Affairs | HistoryLevel of Difficulty: Medium | Factual 3 / 5 Q3. With reference to the Extremely Large Telescope (ELT), consider the following statements:1) It is being built on Cerro Armazones mountain in Chile.2) It is being built by the European Southern Observatory (ESO).3) It is expected to operate effectively without the need for adaptive optics technology due to its altitude and atmospheric conditions.How many of the above statements are correct? Only one Only two All three None Relevance: The world's largest telescope is being built on a mountaintop in Chile.Explanation:The Extremely Large Telescope (ELT), being built by the European Southern Observatory (ESO) in Chile, will be the world's largest optical telescope, with a primary mirror that measures 128 feet (39 meters) across. (Hence, statement 1 is correct)It will be capable of detecting — and possibly even imaging — terrestrial planets in the habitable zones of other stars.The ELT is under construction atop Cerro Armazones, which is a mountaintop in Chile's Atacama Desert. (Hence, statement 2 is correct)Although the ELT will operate at a high altitude to minimize atmospheric interference, it will still be subject to some atmospheric turbulence. Thus, it requires adaptive optics technology to correct for this scintillation and ensure clear images. This technology is crucial for optimizing the telescope's performance despite its advantageous location. (Hence, statement 3 is not correct)Therefore, option (a) is the correct answer.Subject: Current Affairs | S&TLevel of Difficulty: Medium | Factual 4 / 5 Q4. With reference to the International Big Cat Alliance (IBCA), consider the following statements:1) The idea for the IBCA was first proposed by India's Prime Minister in 2019.2) All the Big Cat species covered under the alliance are found in India.Which of the statements given above is/are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Relevance: Recently, India has officially joined the International Big Cat Alliance (IBCA).Explanation:The International Big Cat Alliance (IBCA) is a multi-country, multi-agency coalition of 96 big cat range countries, and non-range countries aimed at conserving 7 big cats and their habitats.The idea was first proposed by India’s Prime Minister in 2019 and officially launched in April 2023 to mark the 50th anniversary of Project Tiger. (Hence, statement 1 is correct)The initiative focuses on the conservation of seven big cat species: the Tigers, Lions, Leopards, Snow Leopards, Cheetah, Jaguar and Puma.Five of these—tiger, lion, leopard, snow leopard, and cheetah—are found in India, excluding the puma and jaguar. (Hence, statement 2 is not correct)Therefore, option (a) is the correct answer.Subject: Current Affairs | EnvironmentLevel of Difficulty: Medium | Factual 5 / 5 Q5. Match the following global efforts to reduce methane emissions with their respective descriptions:Global EffortsDescriptionsA. Global Methane Pledge (GMP)1. Led by the US and EU.B. International Methane Emissions Observatory (IMEO) 2. UN Environment Programme (UNEP)C. Global Methane Tracker (GMT)3. International Energy Agency (IEA)D. Climate and Clean Air Coalition (CCAC)4. Intergovernmental Panel on Climate Change (IPCC)How many pairs given above are correctly matched? Only one pair Only two pairs Only three pairs All four pairs Relevance: According to recent studies, Methane (CH4) emissions are surging, threatening global climate targets set by the Paris Agreement.Explanation:Global Efforts are Underway to Reduce Methane? a) Global Methane Pledge (GMP)It was launched at CoP26 2021 (Glasgow climate pact), and aims to reduce methane emissions by at least 30% below 2020 levels by 2030. Led by the US and EU, the GMP now has 158 country participants representing a little over 50% of global anthropogenic methane emissions. India has opted not to sign the Global Methane Pledge. (Hence, pair 1 is correctly matched)b) International Methane Emissions Observatory (IMEO)UN Environment Programme (UNEP): UNEP leads initiatives like the International Methane Emissions Observatory (IMEO) and the Oil and Gas Methane Partnership to monitor and reduce methane from energy, agriculture, and waste sectors. (Hence, pair 2 is correctly matched)c) Global Methane Tracker International Energy Agency (IEA)’s Global Methane Tracker is an indispensable tool in the fight to bring down emissions from across the energy sector. (Hence, pair 3 is correctly matched)d) Climate and Clean Air Coalition (CCAC)It supports countries in implementing methane reduction measures. It is not led by the Intergovernmental Panel on Climate Change (IPCC) Reports. (Hence, pair 4 is not correctly matched)Therefore, option (c) is the correct answer.Subject: Current Affairs | EnvironmentLevel of Difficulty: Medium | Factual Your score is 0% Restart quiz
