Q 2 / 11

UPSC CSE Prelims 2025

The World Bank warned that India could become one of the first places where wet-bulb temperatures routinely exceed 35 °C. Which of the following statements best reflect(s) the implication of the above-said report?

  1. Peninsular India will most likely suffer from flooding, tropical cyclones and droughts.
  2. The survival of animals including humans will be affected as shedding of their body heat through perspiration becomes difficult.

EXPLANATION

Correct Option (C)

Both statements I and II are correct implications of the World Bank's warning regarding rising temperatures and potential routine exceedance of 35°C wet-bulb temperatures in India.

Statement I: The World Bank's climate risk reports, including the 2022 assessment, indicate that rising temperatures and intensified monsoon patterns due to climate change will increase the vulnerability of regions like Peninsular India. This heightened vulnerability translates into increased risks of extreme weather events such as flooding, tropical cyclones, and droughts.

Statement II: A wet-bulb temperature exceeding 35°C represents a critical threshold for human and animal survival. At this temperature, the body's ability to cool itself through sweat evaporation is severely compromised or becomes ineffective due to high humidity. This leads to an inability to shed excess body heat, resulting in severe heat stress and potentially fatal conditions for living organisms, including humans.

Incorrect Options:

Options 1, 2, and 4 are incorrect because both statements I and II accurately reflect the multifaceted implications of the World Bank's report regarding the risks associated with rising temperatures and high wet-bulb temperatures in India. Option 1 considers only Statement I, Option 2 considers only Statement II, and Option 4 dismisses both, none of which fully capture the comprehensive implications discussed in the report.
