Bangalore: Has CO2 really made the winters colder?

Bearing the chill

...this winter, the chill was too cold for many Bangaloreans to step out, a scene that had many old tongues wagging whether the climate change had finally transformed the City’s weather decisively.

Yet, the scientists have an explanation for the perceptible rise in summer temperatures. “In scientific terms, we call the increase in temperature the urban heat island effect,” says Ravindranath. “Tar and cement roads, concrete buildings, infrastructure projects, lack of greenery and pollution are some of the contributors to the change in the weather pattern,” he explains.

The big spurt in the City’s population has invariably been a factor.

However, the Director of the Bangalore Meteorology Department, B Puttanna, is not convinced by that argument. “It is a common practice that whenever sensitive people find a slight change in the weather, they react immediately. But the data available with us show that there is no substantial change in the weather in the last 100 years,” he says.
...In relative terms, Bangalore’s summers are perceived as hotter and winters colder. The man-made eco-disasters triggered in the name of development is not doing anything to change that perception.
