Chennai Flooding: Single Wettest December Day In 100+ Years; +/-270 Killed, 1 Million Displaced
Extreme rainfall in southern India has killed nearly 270 people and displaced about a million more, as flooding causes major problems in the state of Tamil Nadu.
Chennai, the capital of Tamil Nadu and fourth-most-populous city in India, experienced its wettest December day in over a century this week, according to AccuWeather. That follows a November that brought the city 300 percent more rain than is usual for the month. Monsoon winds typically bring rainfall to Chennai during October, November, and December, but rainfall this year has been exceptional the city and surrounding region has gotten more than 11 inches of rainfall over the last several days, which, as the LA Times reports, is about 75 percent of the average for the whole monsoon season. The rain has been abnormal. People have not seen this rain in their lifetime, Jomey Joseph, head of the Chennai office of Catholic Relief Services, told TIME.
Climate change has been shown to make extreme weather events like flooding more likely and more intense, but its hard to say how much climate change played a role in any one weather event, including Indias floods. Still, the news of Indias flooding has made it to the Paris climate talks, where world leaders are meeting to hash out an international agreement on climate. The unprecedented magnitude of the flooding confirms yet again that we no longer have time. We must take concrete and urgent action against climate disruption, French Foreign Minister Laurent Fabius said.
And its true that, though this current flooding may have been more El Niño-driven than climate-driven, the monsoon rains could be affected as the earth warms. A study last year found that extreme periods of wet and dry weather within Indian monsoon seasons have increased in the last 34 years. Another 2014 study found that Asian monsoons could intensify as temperatures warm and atmospheric carbon dioxide levels climb.
