ACs can raise New Delhi temperatures

New Delhi: In a 'scary' revelation, a recent global report on urban health said that using air-conditioners at night can add one degree celsius to the temperature in a city.
It also says that "heat island effects" can make cities hotter by one to three degrees Celsius during day and one to two degrees celsius warmer in the evening.
While acknowledging that the use of air-conditioners is a difficult problem to resolve in conditions of extreme temperatures, the report by World Health Organisation and UN-Habitat said that one person's air-conditioner can keep them from suffering from heat effects, but the air-conditioner would be exacerbating the city's overall heat.
According to the report, cities experience higher temperatures than rural areas due to what is called the "urban heat island effect". This is the result of a combination of factors emerging from urban built environment and human activities including use of cooling machines and more vehicles.
It further said that the combined impact of the urban heat island effect with a heat wave can be devastating and older adults as well as infants face higher health risk.
In fact, some cities have gone for targeted interventions on rooftops. Toronto was among the first in the world to adopt a policy mandating green roofs for buildings of a certain height. Los Angeles has mandated buildings to adopt lighter coloured reflective roofs. Paris has passed legislation to pursue green roofing and solar panel roofs.
