Explanation

Analyzing the implications of wet-bulb temperatures exceeding 35°C: I. Peninsular India will suffer from flooding, tropical cyclones and droughts: This is not the direct implication of wet-bulb temperature warnings. While these weather events may occur due to climate change, they are not specifically related to wet-bulb temperature thresholds. II. Survival of animals including humans will be affected as shedding body heat through perspiration becomes difficult: Correct. This is the precise implication of wet-bulb temperatures exceeding 35°C. At this threshold, the human body cannot cool itself through sweating, even in the shade with unlimited water, making survival extremely difficult and potentially fatal within hours. The wet-bulb temperature of 35°C represents a critical physiological limit for human survival, regardless of health, age, or fitness level.
