"Climate crisis is at our doorstep, it's in our faces," warns author Amitav Ghosh and asks, "How can we pretend that is happening to other people?" Speaking to NDTV on his new book - 'The Great Derangement: Climate Change and The Unthinkable' - Mr Ghosh says climate change "is first and foremost a cultural problem". "Why do people want to buy building which is right on the sea," he asks, and that why are people in "profoundly water-stressed" Delhi maintaining lawns. He also speaks about how climate change is linked to modern security threats and why he is critical of the Paris Agreement on climate change.
