This is how India's response to the heat wave is fueling the climate catastrophe

Authorities warn of significant health risks, schools in megacities like Calcutta had to close, a news anchor collapsed due to heat stroke during a live television recording: India is suffering from high temperatures, sometimes exceeding 45 degrees.

The heat wave is currently primarily affecting the east and south of the country - and it provides a foretaste for other regions: The meteorological agency IMD expects that temperatures will be unusually high in large parts of the country until June. 

While productivity is falling because of the heat, air conditioning manufacturers are enjoying excellent business: the industry is facing the best summer in its history, a manager told the Times of India newspaper.

30 percent growth is possible this year. The market potential is huge, because only a few Indian households currently have air conditioning installed - but by the next decade, cooling systems are likely to be installed in over 50 percent of all households, estimates the government in New Delhi.
