While the annual monsoon brings rainfall that farmers depend on, scientists say climate change is making the phenomenon more erratic, unpredictable and deadly across the South Asia region. India's northeastern state of Assam is among the hardest hit by the annual rains, with at least 89 people killed, according to Chief Minister Himanta Biswa Sarma. Neighbouring Sri Lanka has also seen unusually heavy monsoon rains that have caused flash floods and mudslides, claiming the lives of at least eight people since Monday, according to the Disaster Management Centre.
