A recent analysis carried out on a little over one thousand incidents of floods in the Himalayan region of Assam has revealed that there has been a significant rise in the frequency of floods since 2000 and that rising temperature is driving the increase. The findings of the study have been published in a recent issue of Science Bulletin, a peer-reviewed international journal, which is sponsored by the Chinese Academy of Sciences and the National Natural Science Foundation of China. It is significant for Assam and the Northeast in particular because the Northeast is situated in the same Himalayan zone where the 1,000-plus incidents of floods have been studied. Based on a new inventory of the types, patterns, and causes of floods in the region stretching back to 1950, the study has confirmed that the frequency of floods has increased over the past seven decades. Additionally, it has also been found that there has been a rise in the unpredictability of the timing of floods. It says that while most flood events continue to occur during monsoons in the larger Himalayan region, there is a marked rise in the number of floods happening outside these times too. Other issues: the study report has brought to light confirmation that planetary heating from the burning of oil, coal, and gas has been driving the rise in all four of the main types of floods seen in the region. It has been said that the two most common reasons behind the recurrence and unpredictability of floods are heavy rains and the rapid melting of snow. There are also increasing incidents of more sudden occurrences of floods due to glacial lake outbursts and landslide-dammed lake outburst floods.
