Using data from the India Meteorological Department (IMD) or newspaper records, find the average monsoon rainfall (June–September, or the local season) for your city or district for 5 years during two decades, such as the 1980s and 2020s. Note any trend (increasing, decreasing, or the total number of days with heavy rain over 50 mm). How can this be connected to warmer Arabian Sea temperatures or changes in land use (forests to farms to cities) as discussed in the chapter?

Tabulate the five-year averages for each decade and compare them. Note whether total rainfall or the number of heavy-rain days has risen or fallen, then link any trend to warmer seas (more evaporation and intense bursts) or land-use change (urban heat and altered albedo affecting local rainfall).
