Thirty-one people have died but at least 170 others remain missing after a glacier broke off a mountainside, triggering a flash flood through a valley in Uttarakhand. "I request the centre to not indulge in debates over whether development has negatively impacted Uttarakhand. Climate change has been a dark reality in its darkest form in the Himalayas for many years" Harish Rawat, former Uttarakhand Chief Minister, told NDTV's Akshay Dongare.
