Journalist Nirmal Ghosh firmly believes global warming is going to cause far more chaos across India in the future. We're talking about mass migrations because of changing weather. That will have implications on politics. Nirmal Ghosh says the steady shrinking of Himalayan glaciers means the entire water system is being disrupted - global warming, he says, will cause even greater extremes. Not everyone agrees.
Some scientists say the glaciers have been shrinking for decades and other factors are to blame.
Certainly, India has a long history of extreme weather patterns - and extremes of temperature across the continent. West blamed Dr RR Kelkar, the director general of the Indian meteorological department, says it is too early for accurate data to be available yet. India is a tropical country, we must remember that. We are used to hot environments, we are used to heavy rains, we are used to cyclones, and really there is no clear statistically significant trend that things are going to change drastically. Scary stories or not, there are also concerns that knowledge being gathered about the impact of global warming is controlled by the West.
