Which among the following gases is most responsible for global warming?
Correct Answer:
(C)
Carbon-dioxide
Greenhouse gases in the environment are water vapour, Carbon Dioxide, Methane, Nitrous oxide and Chlorofluorocarbons. Among these, carbon dioxide is most responsible for global warming as its concentration in the environment is more as compared to other greenhouse gases. Notably, the concentration of carbon dioxide is increasing in the atmosphere.

As a result of global warming there has been:
Better global communication
Melting of glaciers
Flowering of mango trees before times
Adverse impact on health

Correct Answer:
(B)
2, 3 and 4 are correct
As a result of global warming, glaciers are melting worldwide. Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active. Global warming would have an adverse impact on human health. The main categories of health risks include (i) Direct-acting effects (ii) Impacts mediated via climate-related changes in ecological systems and relationship (eg; crop fields, mosquito ecology, marine productivity).

Global Warming is caused due to the emission of:
Correct Answer:
(B)
Carbon Dioxide
Global warming is primarily a problem of too much carbon dioxide in the atmosphere. This carbon overload is caused mainly when we burn fossil fuels like coal, oil and gas or cut down and burn forests. The presence of carbon dioxide in the atmosphere was 315 PPM (Parts per million) in 1950. Currently, it has crossed 415 PPM. If the increase of carbon dioxide continues in the atmosphere at this speed, it will reach approximately 650-950 PPM by the end of the 21st century. This will raise the earth's temperature by 6°C.

Which one of the following is the most fragile ecosystem that will be first affected by global warming?
Correct Answer:
(A)
The Arctic and Greenland Ice sheet
The Arctic and Greenland ice sheet are the most fragile ecosystem that will be first affected by global warming. The melting of ice in this area will also affect the entire earth.
Ques:

Which of the following is not related to the astronomical theories of climate change?
Correct Answer:
(D)
Solar irradiance
Astronomical theory of climate change was propounded in 1920 by astronomer Milutin Milankovic. It states that the variation in eccentricity, axial tilt and precession of the Earth’s orbit determines climatic patterns on Earth through orbital forcing. Hence, solar irradiance is not concerned with this theory.
Ques:
26
Who had suggested that shifting Earth on its axis is one of the factors, responsible for the climatic change?
Correct Answer:
(B)
Milutin Milankovic
According to the astronomical theory of climate change, Earth's movement produces an effect on climate change. In 1920, Serbian geophysicist and astronomer Milutin Milankovic theorized that variation in eccentricity, axial tilt and precession of the earth's orbit results in cyclical variation in the solar radiation reaching the earth. This orbital forcing influences climatic pattern on earth.

United Nations Climate Action Summit, 2024 was held at which of the following cities?
Correct Answer:
(D)
Baku
The UN climate conference in Baku, Azerbaijan, concluded on 24 November 2024 with an agreement calling on developed countries to deliver at least $300 billion per year to developing countries by 2035 to reduce greenhouse gas emissions and protect lives and livelihoods from the worsening impacts of climate change. The main theme of the UN climate conference was "Strengthening Ambitions and Ensuring Action"

With reference to 'Global Climate Change Alliance', which of the following statements is/are correct?
It is an initiative of the European Union.
It provides technical and financial support to targeted developing countries to integrate climate change into their development policies and budgets.
It is coordinated by the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD).
Select the correct answer using codes given below:
Correct Answer:
(A)
1 and 2 only
The GCCA was established by the European Union (EU) in 2007 to strengthen dialogue and cooperation with developing countries, in particular, least developed countries (LDCs) and small island developing states (SIDS). It started its work in just 4 countries. Today it has a budget of more than £ 300 million and is one of the most significant climate initiatives in the world. It supports 51 programmes around the world and is active in 38 countries, 8 regions and sub-regions and at the global level. It completes its goal through two interactive strong pillars. These include providing technical and financial assistance to targeted developing countries for the integration of climate change in their development policies and budgets. The overall aim of GCCA is to create a new treaty between the European Union and the poor developing countries, who have the least potential to deal with climate change. It is coordinated by the European Commission (EC).

Which of the following statements is incorrect for ‘Green Climate Fund” (GCF)?
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 the code given below.
Correct Answer:
(A)
1 Only
Statement 1 is correct: The Green Climate Fund (GCF) is designed to support developing nations in implementing adaptation and mitigation strategies to combat climate change. Its goal is to provide financial assistance to help these countries reduce greenhouse gas emissions and cope with the effects of climate change.
Statement 2 is incorrect: The GCF was not established by the UNEP, OECD, Asian Development Bank, or World Bank. It is an independent financial entity created under the framework of the United Nations Framework Convention on Climate Change (UNFCCC).
