Climate scientists warn that climate change is intensifying heatwaves in India, with the cooling effects of La Nia potentially becoming less effective in a warmer future. The India Meteorological Department (IMD) predicts an early summer with above-normal temperatures and intense heatwave spells, following an unusually dry winter and the warmest February since 1901. Experts emphasize the role of human-caused climate change, along with natural climate drivers like El Nio and La Nia, in shaping weather patterns. While La Nia typically brings cooler temperatures, scientists suggest that under climate change, its ability to mitigate heatwaves may be diminished.
