Additional Test (Part - 3) - Question 1

Consider the following statements concerning Black Carbon:

1. Black carbon is the result of incomplete combustion of fossil fuels, biofuel, and biomass.

2. It is directly emitted in the atmosphere as fine particles PM5.

3. Black carbon warms the atmosphere by reducing albedo when deposited on snow and ice.

4. Lifetime of black carbon in the atmosphere is more than 100 years.

Which of the above statements is/are correct?

Detailed Solution for Additional Test (Part - 3) - Question 1 Answer is BLACK CARBON remains in the atmosphere for only a few weeks, so cutting its emissions would immediately reduce the rate of warming, particularly in the rapidly changing Arctic.

Additional Test (Part - 3) - Question 2

Which of the following can be the possible impacts of climate change on agriculture?

1. Increased crop yields in temperate regions.

2. Decreased amount of arable land in the high latitude region.

3. Increased fertilizer requirement.

4. Reduction in agricultural production variability.

Select the correct answer using the code given below:

Detailed Solution for Additional Test (Part - 3) - Question 2 As a result of the thawing of snow, the arable land in high-latitude regions is likely to increase. Increased frequencies of droughts, floods, storms, and cyclones are likely to increase agricultural production variability

Additional Test (Part - 3) - Question 3

What does the term “internal carbon price” refer to?

Detailed Solution for Additional Test (Part - 3) - Question 3

HOW CARBON PRICING YIELDS BENEFITS FOR BUSINESSES

  • Companies employing an internal carbon price can better manoeuver in regulatory environments where GHG emissions reductions are mandatory - such as EU, Canada, and are more responsive to external carbon prices.

  • Many companies find that after setting absolute emission reduction and intensity goals, internal carbon price helps them evaluate returns on related investments and incentivize employees to meet established corporate targets.

  • Internal carbon pricing encourages innovation and sustained economic competitiveness. It also helps companies identify organizational inefficiency that is adding to overall costs.

  • It helps prepare for the forecasted low carbon economy and to increase their efficiency and market profitability.

Additional Test (Part - 3) - Question 4

What are the differences between ecology, environment, and ecosystem?

1. Ecology revolves around the relationship between environment and living organisms while the ecosystem is the functional unit of the biosphere.

2. While the environment is static, an ecosystem varies greatly in size and elements.

Select the correct answer using the code given below:

Detailed Solution for Additional Test (Part - 3) - Question 4
  • Ecology is the study of interactions between organisms, organisms and the surroundings occurring within an ecosystem or environment.

  • An ecosystem is a functional unit of the environment (mostly biosphere).

  • An environment is a group of ecosystems.

Additional Test (Part - 3) - Question 5

Consider the following pollutants:

1. Carbon Monoxide (CO)

2. Oxides of nitrogen (NOX)

3. Suspended Particulate Matter (SPM)

4. Unburnt hydrocarbons

Which of the pollutants given above are released from vehicular emissions?

Detailed Solution for Additional Test (Part - 3) - Question 5
  • Vehicles are mainly responsible for more than 80 per cent of total air pollution. The major pollutants released from automobiles, locomotives, aircraft, etc., include Carbon Monoxide (CO), Unburnt hydrocarbons and nitrogen monoxide, nitrogen dioxide, suspended particulate matter emissions.

  • In metropolitan cities, vehicular exhausts account for most of the CO, hydrocarbons, oxides, and suspended particulate matter emissions.

Additional Test (Part - 3) - Question 6

Which of the following are the possible impacts of Climate Change?

1. Improved agricultural yield in higher latitudes

2. Reduction in biodiversity in the alpine regions

3. Reduction in corals in the tropical oceans

Select the correct answer using the code given below.

Detailed Solution for Additional Test (Part - 3) - Question 6 Climate and agricultural zones are likely to shift towards the poles. Increased temperature will impact agriculture production. Higher temperatures reduce the total duration of the crop cycle by inducing early flowering

Additional Test (Part - 3) - Question 7

It is a potent greenhouse gas. The transpiration and evaporation increase its concentration in the atmosphere. Its concentration greatly varies from season to season and region to region. It is one of the highest contributors to the warming of the earth due to its capacity to absorb both incoming and terrestrial radiation.

The greenhouse gas being described here is:

Detailed Solution for Additional Test (Part - 3) - Question 7
  • The most dominant greenhouse gas overall is water vapour, but it has a very short atmospheric lifetime (about 10 days). Water vapour is also a variable gas in the atmosphere, which decreases with altitude.

  • Water vapour also decreases from the equator towards the poles. In the warm and wet tropics, it may account for four per cent of the air by volume, while in the dry and cold areas of desert and Polar Regions, it may be less than one per cent of the air.

  • One unique feature about this greenhouse gas is that it absorbs both incoming and outgoing solar radiation.

Additional Test (Part - 3) - Question 8

Consider the following statements about the causes of climate change:

(1) Evolution of life

(2) Orbital variations of Earth

(3) Anthropogenic GHG emissions

(4) Ocean-Atmosphere interactions

Which of the above are considered as ‘external climate forcing’?

Detailed Solution for Additional Test (Part - 3) - Question 8
  • Earth’s climate system is considered to be composed of five components, which include atmosphere, hydrosphere, cryosphere, lithosphere and biosphere.

  • Any change in climate arising due to automatic changes in these is considered to be ‘internal variability’. Evolution of life and Ocean-atmosphere interaction falls in this category.

  • On the other hand, climate change resulting from sources other than Earth’s climate system is considered a result of external forcing.

  • Orbital variations of Earth and Anthropogenic GHG emissions fall in this category. It can be noted that GHG emission can also be natural (e.g. from peatlands) in which case it will not be part of external forcing.

Additional Test (Part - 3) - Question 9

Which of the following statements is/are correct?

1. The coral reefs that India has in its biosphere reserves are also saline sensitive and thus the rising sea level threatens their existence.

2. Mountain ecosystems are hot spots of biodiversity. However, the increase in temperature and human activities are flourishing biodiversity.

Codes:

Detailed Solution for Additional Test (Part - 3) - Question 9
  • The coral reefs that India has in its biosphere reserves are also saline sensitive and thus the rising sea level threatens their existence.

  • Mountain ecosystems are hot spots of biodiversity. However, the increase in temperature and human activities are deteriorating biodiversity.

Additional Test (Part - 3) - Question 10

Consider the following statements:

1. Carbon sequestration describes short- term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming

2. Sulphur-dioxide gas useful for mitigating global warming

3. Green Carbon refers to coastal, aquatic and marine carbon sinks held by the indicative vegetation, marine organism and sediments.

Which of the above statements is INCORRECT?

Detailed Solution for Additional Test (Part - 3) - Question 10
  • Carbon sequestration describes short- term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming.

  • Green carbon is the carbon stored in the biosphere. We call it ‘green’ because carbon is taken up from the atmosphere by plants through the process of photosynthesis, which is dependent on the green chlorophyll pigment found in plant leaves.
