My current research focuses on the increasing frequency of inter-annual climate variability, driven by phenomena like the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD), even amid a long-term global warming trend. Based on recent studies using CMIP5 and CMIP6 models, my concern lies in the growing disruptions to climate-vulnerable countries.

These climate events significantly affect rainfall patterns, sea levels, and the frequency of tropical cyclones. The latest IPCC AR6 report highlights the urgent need to prioritize climate adaptation strategies, particularly for regions like South Asia.

Water-stressed countries, including Bangladesh, are especially vulnerable to heat stress during El Niño and flooding caused by La Niña. Both pose significant threats to the water resources sector in Bangladesh, which, in turn, has wide-ranging social and economic impacts.
