Between 1891 and 2020 only 50 cyclones have formed in September in the Indian subcontinent. They are mainly formed in October and November -the main cyclone regenerating months. Since cyclones started getting officially monitored in 1975, only 11 have formed in September – 6 in the Bay of Bengal and 5 in the Arabian Sea.

On July 1, 2021, Delhi experienced a heatwave, when the maximum temperature rose to 43.5°C. At the same time, Ganganagar, in west Rajasthan, reported India's highest temperature of 44.5°C.

IPCC’s* sixth assessment report (AR6) has bad news for the future. The warming beyond 1.5°C or 2°C will be breached much earlier. Average global temperatures will continue to rise and could increase by 5.7 °C by the end of this century compared to 1850–1900.Consequently, the land surface will continue to warm more than the ocean surface. The Arctic will continue to warm more than global surface temperature. Extreme changes become larger with every addition to global warming.

China’s central Henan province witnesses its heaviest rainfall in 1,000 years. At least 25 people, including 12 subway passengers, have been killed in the rainstorm so far.
