Scientists say that climate change was likely to have made the rains that unleashed catastrophic flooding across Bangladesh worse. While South Asia’s monsoon rains follow natural atmospheric patterns, the rains will become more erratic and torrential as global temperatures continue to climb, scientists say. It would take months to determine exactly how much of a role climate change played in last week’s heavy rains. But scientists note that warmer air can hold more water vapour before rain clouds eventually burst, meaning more rain eventually pours down. “The strong monsoon winds in the Bay of Bengal can carry a lot more moisture,” said Roxy Mathew Koll, a climate scientist at the Indian Institute of Tropical Meteorology. “The large amount of rainfall that we see now might be a climate change impact.” The South Asia monsoon season, from June to September, is governed by several, overlapping […]
