Current Affairs Question - 28 March 2022

Consider the following statements:

1. According to a recently published study, the difference between a scenario where the Earth will be warmed by upto 1.8 degrees Celsius by the end of the 21st century and a scenario where the Earth will be warmed by upto 3.6 degrees Celsius depends on the social system.
2. The study says that there is a “strong probability” of warming between 1 and 2 degrees Celsius at the end of the century.
3. As regards global warming, one of the most prominent temperature-control goals is the figure of 1.5 degrees Celsius, which is the target set out by the 2015 Paris Climate Agreement that was signed by 195 countries in 2015.

Which of the above statement(s) is/are true?

Consider the following statements:

1. A recent study conducted by Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, has shown that water vapour exhibits a positive radiative effect at the top of the atmosphere, suggesting an increase in overall warming in the high altitude Himalayas due to it.
2. Aerosol-cloud-precipitation interactions over this region, which are one of the most climate-sensitive regions, are poorly understood, apparently, due to a lack of proper observational data.
3. Precipitable Water Vapour (PWV) is one of the most rapidly varying components in the atmosphere and is mainly accumulated in the upper troposphere.

Which of the above statement(s) is/are true?
