Abstract

Human-induced climate change has warmed the atmosphere, ocean, and land, and is already affecting every region of Earth in multiple ways; and the recent climatic changes are widespread, rapid and intensifying, and unprecedented in thousands of years (IPCC AR6, 2021). Climate change is already affecting every inhabited region across the globe with human influence contributing to many observed changes in weather and climate extremes, and larger projected changes in the frequency and intensity of extremes with every additional increment of global warming. This talk will discuss the consequences of climate change on weather extremes, monsoon rainfall and associated disasters over the Indian subcontinent, particularly focusing on the Himalayan region, and highlight the importance of satellite, remote-sensing and insitu observations; and weather / climate models for advancing our predictive understanding of the regional monsoon precipitation extremes in a warming world.

Poster

Short Biography
Dr. Krishnan Raghavan specializes in climate modeling to understand scientific issues relating to “Climate Change, Asian Monsoon and Water Cycle”. Under his leadership the Centre for Climate Change Research (CCCR) @ IITM, Pune, developed the first Earth System Model (ESM) from India that contributed to the CMIP6 and IPCC Sixth Assessment Report. He was a Coordinating Lead Author in the IPCC AR6 WG1 report (Chapter-8: Water Cycle Changes) and a Drafting Author in the Summary for Policymakers. He is a Member of the Joint Scientific Committee (JSC), World Climate Research Programme (WCRP), World Meteorological Organisation (WMO). He and his team from CCCR-IITM published the First National Climate Change Assessment Report of the Ministry of Earth Sciences, Govt of India in 2020. After obtaining M.Sc degree in Applied Mathematics from the Madras Institute of Technology, Chennai, he pursued Ph.D. research in Atmospheric Sciences at the Physical Research Laboratory, Ahmedabad. He was awarded Ph.D. degree from Univ. of Pune in 1994. He has published over 160 scientific articles/papers, supervised/co-supervised 26 Ph.Ds [20 (degree awarded) + 1 (submitted) + 5 (ongoing)] & 7 Master (M.Sc/M.Tech) dissertation. He offered training lectures in Geophysical Fluid Dynamics & Atmospheric Sciences.
