Global
Warming to
Triple Frequency of
Drought, Floods Along Indian Ocean
The
Frequency of extreme forms of a climate cycle that can cause devastating droughts and flood events from Indonesia to India to Kenya, may
Triple in the coming decades, according to a new study published Wednesday. The study, published in the journal
Nature, ties manmade
Global Warming to shifts in the behavior of a naturally-occurring climate cycle, k**wn as the
Indian Ocean Dipole (IOD).
Like the Pacific Ocean, which gives rise to
El Niño and La Niña events, the
Indian Ocean has its own inherent instability, with constant fluctuations between trade winds and sea surface temperatures across the
Ocean basin. These fluctuations, like oceanic and atmospheric mood swings, can interact in reinforcing feedback cycles, leading to positive or negative Dipole events that lead to huge changes in where it rains and how frequently and heavily it does so
