Cyclones in the Bay of Bengal are becoming more intense, potent, and destructive because of climate change, which is warming the oceans at an alarming speed and allowing cyclones to retain their energy for longer. Bangladesh and Myanmar are particularly threatened because they're low-lying and are home to some of the world's poorest populations.
There's no real evidence that cyclones are arriving more often due to climate change. While some types of extreme weather can be directly attributed to global warming, more research is needed to conclude that climate change directly affects cyclones' frequency and power. As cyclones are unavoidable natural disasters, policies to boost disaster preparation are crucial to limiting damage once calamity strikes.
There's a 50% chance that there be at least 2.37˚C of global warming by 2100, according to the Metaculus prediction community.
