Global heating supercharging Indian Ocean climate system
The Guardian, 11/19/2019

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.

It is similar to El Niño and La Niña in the Pacific, which cause sharp changes in weather patterns on both sides of the ocean.

Recent research suggests ocean heat has risen dramatically over the past decade, leading to the potential for warming water in the Indian Ocean to affect the Indian monsoon, one of the most important climate patterns in the world.

“There has been research suggesting that Indian Ocean dipole events have become more common with the warming in the last 50 years, with climate models suggesting a tendency for such events to become more frequent and becoming stronger,” Ummenhofer said.

She said warming appeared to be “supercharging” mechanisms already existing in the background. “The Indian Ocean is particularly sensitive to a warming world. It is the canary in the coalmine seeing big changes before others come to other tropical ocean areas.”

This is our future. The world is either on fire, or under water.
