Greenhouse Effect and Climate Change (Part-II)

Total Questions: 50

31. United Nations Conference on climate change, COP 21 was held in [U.P.P.C.S. (Pre) 2018]

Correct Answer: (b) Paris
Solution:The 2015 United Nations Climate Change Conference (COP21) was held in Paris. It was the 21st yearly session of Conference of Parties (COP) to the 1992 United Nations Framework Convention on Climate Change (UNFCC) and the 11th session of the Meeting of the Parties to the 1997 Kyoto Protocol.

The COP 27 Summit was held in Egypt's Sharm El Sheikh City in Nov., 2022.

32. What is not True about the commitment made by India at UNFCC COP 26 Conference?

Correct Answer: (a) By 2030, India will reduce its carbon emission by one billion tons.
Solution:India will achieve net-zero emissions latest by 2070. This is notable given that so far India was the only major emitter that had not committed to a timeline to achieve net-zero carbon dioxide emissions and has also argued against the concept of net-zero carbon targets.

Renewable energy would be tapped in a big way in India. By 2030, India will ensure 50% of its energy will be sourced from renewable sources. India plans to generate 500 GW of renewable energy by 2030. This marks a 50 GW increase from its current target of 450 GW.

India also committed to reducing its carbon emissions until 2030 by a billion tonnes. By 2030, India will reduce the carbon intensity of its economy to less than 45 per cent. India is largely on track to meet, and even exceed, its Paris Agreement targets: reduce emissions' intensity of its gross domestic product (GDP) by 33 to 35 percent from 2005 levels by 2030

33. The United Nations Framework Convention on Climate Change (UNFCCC) is an international treaty drawn at: [I.A.S. (Pre) 2010]

Correct Answer: (b) UN Conference on Environment and Development, Rio-de-Janeiro, 1992
Solution:The United Nations Framework Convention on Climate Change (UNFCCC) is an international environmental treaty adopted at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio-de-Janeiro from 3 to 14 June, 1992.

34. "Momentum for Change : Climate Neutral Now" is an initiative launched by: [I.A.S. (Pre) 2018]

Correct Answer: (c) The UNFCCC Secretariat
Solution:The "Momentum for Change: Climate Neutral Now" is an initiative launched by the UNFCCC secretariat. It was launched as a part of larger efforts to showcase successful climate action around the world.

The UNFCCC secretariat launched its Climate Neutral Now initiative in 2015.

It is an initiative launched to urge individuals, companies, and governments to measure their climate footprint, reduce their greenhouse gas emissions as much as possible. The secretariat in 2016 launched a new pillar under its Momentum for Change initiative focused on Climate Neutral Now, as part of larger efforts to showcase successful climate action around the world. Climate neutrality is a three-step process, which requires individuals, companies, and governments to:

  • Measure their climate footprint;
  • Reduce their emissions as much as possible;
  • Offset what they cannot reduce with UN certified emission reductions.

35. The United Nations Frame work Convention on Climate Change deals with- [60th to 62nd B.P.S.C. (Pre) 2016]

Correct Answer: (d) Greenhouse gases emission mitigation
Solution:The ultimate objective of all three agreements under the UNFCCC is to stabilize greenhouse gas concentrations in the atmosphere at a level that will prevent dangerous human interference with the climate system, in a time frame which allows ecosystems to adapt naturally and enables sustainable development.

36. Which of the following statements is incorrect for "Green Climate Fund" (GCF)? [U.P.P.C.S. (Mains) 2013]

Correct Answer: (a) It was established in the Durban Conference on Climate change.
Solution:Green Climate Fund (GCF) was formally established during the 2010 United Nations Climate Change Conference in Cancun, Mexico.

It is a fund within the framework of the UNFCCC founded as a mechanism to assist developing countries in adaptation and mitigation practices to counter climate change. The GCF is based in the Songdo Business district of Incheon, South Korea.

It is intended to be the centerpiece of efforts to raise climate finance of $ 100 billion a year by 2020.

37. Which of the following statements regarding the 'Green Climate Fund' is/are correct? [I.A.S. (Pre) 2015]

1. It is intended to assist the developing countries in adaptation and mitigation practices to counter climate change.

2. It is founded under the aegis of UNEP, OECD, Asian Development Bank and World Bank.

Select the correct answer using codes given below:

Correct Answer: (a) 1 only
Solution:Green Climate Fund (GCF) was founded as a mechanism to assist developing countries in adaptation and mitigation practices to counter climate change. The fund is governed by GCF Board.

Hence statement (2) is not correct.

  • It is the world's largest dedicated climate fund which was set up at COP 16 held in Cancun in 2010.
  • It is an operating entity of the financial mechanism of the United Nations Framework Convention on Climate Change (UNFCCC).
  • It accelerates transformative climate action in developing countries through a country-owned partnership approach and use of flexible financing solutions and climate investment expertise.
  • The GCF is a legally independent institution with a fully independent secretariat headed by an Executive Secretary.
  • The Secretariat, located in Songdo South Korea, began its work in December 2013.

38. Consider the following statements regarding 'Earth Hour' : [I.A.S. (Pre) 2014]

1. It is an initiative of UNEP and UNESCO.

2. It is a movement in which the participants switch off the lights for one hour on a certain day every year.

3. It is a movement to raise awareness about climate change and the need to save the planet.

Which of the statements given above is/are correct?

Correct Answer: (c) 2 and 3 only
Solution:Earth Hour is a worldwide movement for the planet organized by the World Wide Fund for Nature (WWF).

The event is usually held worldwide annually encouraging individuals, communities, households and businesses to turn off their non-essential lights for one hour, from 8.30 to 9.30 p.m. towards the end of March, as a symbol of their commitment to the planet.

It was famously started as a lights-off event in Sydney, Australia in 2007. In 2024, Earth Hour was celebrated on March 23.

39. United Nations Climate Action Summit, 2019 was held at which of the following cities? [U.P.P.C.S. (Pre) 2019]

Correct Answer: (d) New York
Solution:United Nations Climate Action Summit 2019, was held at the headquarters of the United Nations in New York City on 23 September 2019. The summit was convened on the theme, "Climate Action Summit 2019: A Race We can Win. A Race We Must Win."

The Climate Action Summit reinforced the global understanding that 1.5°C is the socially, economically, politically and scientifically safe limit to global warming by the end of this century, and to achieve this, the world needs to work to achieve net zero emissions by 2050. The Summit also demonstrated the need to urgently update and enhance countries' short-term commitments by 2020, and their mid-term commitments by 2030, which will be captured in their national climate plans, known as Nationally Determined Contributions to the Paris Agreement.

40. Scientists of Manchester University Recently suggested controlling global warming by cloud brightening over the Pacific Ocean through geo-engineering. Which of the following substances is used for this? [U.P.P.C.S. (Mains) 2009]

Correct Answer: (c) Sea water
Solution:Scientists of Manchester University have suggested using sea water for creating brightening clouds for maximum reflection of sun rays. This will help control global warming. Marine cloud brightening (MCB) aims to increase the brightness of marine clouds by enhancing their reflectivity. It achieves this by releasing tiny sea water droplets into the atmosphere using water cannons or special ships. When these droplets evaporate, they leave behind salt particles. These particles act as nuclei for cloud formation, leading to denser and brighter clouds.
