Overview
- Since May, Greenpeace and resident volunteers in neighbourhoods such as Sunder Nagri and New Seemapuri have kept weekly heat diaries and used thermal cameras to record lived heat exposure.
- In-home and street measurements documented bedroom walls at about 37–45°C and road surfaces up to 60°C, values that are much higher than nearby official station averages.
- Doctors and diarists report heat exhaustion, heatstroke, dehydration, sleeplessness and work absences that have cut wages and disrupted study and household routines.
- Official monitoring in Delhi is sparse and sited in cooler government campuses, and the city has not classified heatwaves as a disaster, limiting access to targeted funds and relief.
- Campaigners plan to publish the diaries as a public archive and pursue legal and policy pressure while researchers warn that heat deaths are likely undercounted and require more localised planning.
