Global heating supercharging Indian Ocean climate system

Indian Ocean dipole events, linked to bushfires and floods, are becoming stronger and more frequent, scientists say

Global heating is "supercharging" an increasingly dangerous climate mechanism in the Indian Ocean that has played a role in disasters this year including bushfires in Australia and floods in Africa.

Scientists and humanitarian officials say this year's record Indian Ocean dipole, as the phenomenon is known, threatens to reappear more regularly and in a more extreme form as sea surface temperatures rise.
