Sharjah24 – AFP: Indian officials said Friday that at least 40 people had perished in the flash floods that had inundated the northeast of India, and army troops were planning helicopter rescues for more of the thousands of people who were trapped in the storm.
Violent torrents stuck the remote state of Sikkim on Wednesday after the sudden bursting of a high-altitude glacial lake near India's borders with China and Nepal.
Climate scientists warn that similar disasters will become an increasing danger across the Himalayas as global temperatures rise and ice melts.
Downstream search-and-rescue teams recovered more bodies overnight as the waters cut a swathe through the countryside towards the Bay of Bengal.
V.B. Pathak, the top civil servant in Sikkim state, said that his office had confirmed 19 deaths.
Shama Parveen, a district magistrate in neighbouring West Bengal, said that an additional 21 bodies had been recovered in her state over the past three days.
Roads, bridges and telephone lines have been destroyed across much of the state, complicating evacuations and efforts to communicate with thousands cut off from the rest of the country.
Nearly 8,000 others were taking shelter at makeshift relief camps set up at schools, government offices and guesthouses, according to a state government bulletin.
An Indian army statement said that soldiers on rescue operations had been able to account for nearly 1,500 people visiting from out of state who were still marooned in the worst-hit flood areas.
"There may be a window of opportunity for evacuation of stranded tourists by helicopters" with weather conditions improving on Friday, the statement added.
Army helicopters were also air-dropping supplies to clusters of stranded people, Pathak told reporters.
"We are putting all efforts to provide relief materials to people and in restoring infrastructure," he added.
India's government said it had expedited funding for relief and recovery efforts, with Prime Minister Narendra Modi promising "all possible support" for those affected.
- 'Root cause is climate change' -
The water surge came after intense rainfall burst the high-altitude Lhonak Lake, which sits at the base of a glacier in peaks surrounding the world's third-highest mountain, Kangchenjunga.
Water powered downstream, adding to a river already swollen by monsoon rains, damaging a dam and sweeping away houses.
Himalayan glaciers are melting faster than ever due to climate change, exposing communities to unpredictable and costly disasters, according to the International Centre for Integrated Mountain Development (ICIMOD) research group.
"The root cause is climate change and this going to increase in the future," ICIMOD climate change specialist Arun Bhakta Shrestha said.
"None of the scenarios are good," he added. "Even the most modest scenario tells us that... similar glacial lake outbursts flood events are very likely."
Earth's average surface temperature has risen nearly 1.2 degrees Celsius since pre-industrial times but high-mountain regions around the world have warmed at twice that pace, climate scientists say.
Among the dead are six Indian army soldiers posted in Sikkim, which sits on India's remote frontiers with Nepal and China, and boasts a sizeable military presence.
India has been wary of China's growing military assertiveness and their 3,500-kilometre shared frontier has been a perennial source of tension, with parts of Sikkim claimed by Beijing.
