Climate change is blamed for the sustained rise in the average temperature, making day to day life difficult and causing sudden changes in the weather patterns

It is clear that the increasing frequency and severity of heat waves are not mere anomalies but evidence of a sustained transformation in a weather pattern caused by climate change.

Dangerous heat waves are likely to hit much of the world more frequently – three times more often than today in some regions. Tropical regions, including India, may face extreme heat conditions almost daily by the end of this century.

The past few months saw an especially severe heat wave in South Asia. D. Raghunandan of the Delhi Science Forum talks about its impact and the possible reasons

The study predicts that the chances of extreme heat waves would increase to every 1.15 years towards the end of this century
