Blog 6 Pollution making Delhi winter days colder?



According to the article, “Pollution making Delhi winter days colder?” written by Amit Bhattacharya stated that the rising air pollution might not just be a health issue but also a part of changing the weather. Bhattacharya stated that for, smog and haze, all linked to atmospheric pollution, causing temperatures during the day to drop and winter being colder than it usually was. R K Jenamani, an office’s director-in-charge had written a paper in 2007 on the link between pollution, fog and daytime temperatures in the capital, stating that the falling trend in January’s average maximum temperature is not only continued but actually had accelerated. In Jenamani’s paper, he also stated that there was a strong correlation between low maximum temperatures in Delhi’s winter, foggy days and high pollutions levels. Bhattacharya also stated that air pollution could be increasing aerosols in the air which becomes fog droplets and increased fog formation under the right conditions. In which, daytime fog suppresses the maximum temperature output by blocking the sunlight. According to Krishna AchutaRao, stated that "High concentration of aerosols in the air would dim surface temperature by decreasing the intensity of sunlight reaching the surface. This has been seen across the globe."
This article is stating that because of air pollution the weather in India had become colder. It also stated that there was a correlation between the decreasing temperatures and the high pollution levels. The only thing wrong with this article is that it didn’t state what the cause or problem of air pollution in the area was. All it stated was because of high pollution levels the temperatures started decreasing.
