Q 1.Consider the following statements:

1. As per the recently released Special Report on Global Warming of 1.5˚C India could annually experience conditions like the 2015 heatwave if the average global temperature rises by more than 1˚C from the present.

2. The Paris Climate Pact calls for efforts to be pursued to limit the temperature increase to 1.5˚C above pre-industrial levels.

Which of the statements given above is/are correct?

a) 1 Only
b) 2 Only
c) Both 1 and 2
d) Neither 1 nor 2
Solution:   c Explaination    https://www.thehindu.com/todays-paper/india-faces-threat-of-deadly-heat-waves-says-un-climate-report/article25162124.ece
The 2015 agreement in Paris, considered a landmark achievement, had the world agree to keep temperatures below 2 degrees Celsius and "pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels."

Q 2. The term 'Ghost nets' refer to

a) An American private military company security contracting in the Iraq War
b) Fishing nets that have been left or lost in the ocean
c) Internet that isn’t visible to search engines
d) None of the above
Solution:   b Explaination    https://www.thehindu.com/sci-tech/energy-and-environment/picking-out-silent-ghosts-in-the-deep/article25146517.ece
Ghost nets are classified under Abandoned, Lost or otherwise Discarded Fishing Gear(ALDFG), which includes lines, traps, hooks, dredges and buoys. Ghost nets can kill marine wildlife, including vulnerable species, and destroy the benthic ecosystems that exist at the lowest level of a body of water. The problem has been worsening with the global expansion in fishing operations, and the availability of more durable gear.

Q 3. To limit global warming to 1.5˚C, the Special Report on Global Warming of 1.5°C sets which of the following targets?

1. By 2030, global emissions must decline by 45% from 2010 levels.

2. By 2040, global net zero emissions must be achieved.

3. By 2050, renewables must provide up to 85% of global electricity.

Which of the statements given above is/are correct?

a) 1 Only
b) 2 Only
c) Both 1 and 2
d) Neither 1 nor 2
Solution:   c Explaination    https://www.thehindu.com/todays-paper/tp-life/safari-in-wild/article25152184.ece
Five steps to 1.5°C –

1. Global emissions of CO2 need to decline by 45% from 2010 levels by 2030

2. Renewables are estimated to provide up to 85% of global electricity by 2050

3. Coal is expected to reduce to close to zero

4. Up to 7 million sq km of land will be needed for energy crops (a bit less than the size of Australia)

5. Global net zero emissions by 2050

2. They are amphibiotic

Which of the statements given above is/are correct?

a) 1 Only

Q 5.With reference to key points from the Special Report on Global Warming of 1.5°C released last month, consider the following statements:

1. As opposed to previous approaches of IPCC’s study of warming, this report clearly links lifestyle choices with warming.

2. Rapid and far-reaching changes must take place in energy generation, land use, cities and industry to limit warming to 1.5˚C.

3. Limiting warming to 1.5˚C brings a lot of benefits compared with limiting it to 2˚C.

a) 1 and 2 Only
b) 2 and 3 Only
c) 1 and 3 Only
d) 1, 2 and 3
Solution:   d Explaination   https://www.bbc.com/news/science-environment-45784892
Where this new study from the IPCC differs from previous approaches is that it clearly links lifestyle choices with warming. The report’s authors say that rapid changes must take place in four key parts of society: • energy generation • land use • cities • industry
