Roxy Mathew Koll is a climate scientist at the Indian Institute of Tropical Meteorology (IITM), Pune.[1][2] His research focuses on climate change and extreme weather events in the Indo-Pacific region, with significant contributions to the understanding of Indian Ocean warming, monsoon dynamics, heatwaves, and tropical cyclones.[1][3][4][5] He was involved in writing the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate and the Sixth Assessment Report.[6][7][8]

Education

[edit]

Koll completed a B.Sc. in physics from CMS College Kottayam,[9] followed by an M.Sc. in physical oceanography from Cochin University of Science and Technology, India.[10][11] He completed his Ph.D. in Ocean and Atmospheric Dynamics from Hokkaido University, Japan, in 2007.[10][12]

Career

[edit]

Koll worked as a Research Scientist at the Euro-Mediterranean Center on Climate Change (CMCC) in Bologna, Italy, from 2008 to 2010.[10] Since 2010, he has worked as a scientist at IITM, Pune, involved in projects related to ocean observations, climate modeling and earth system research. He also holds a concurrent position as a Professor at the Academy of Scientific and Innovative Research (AcSIR). He was a visiting scientist at the National Oceanic and Atmospheric Administration (NOAA), at the National Centers for Environmental Prediction (NCEP) in Maryland in 2012, and at the Pacific Marine Environmental Laboratory (PMEL) in Seattle from 2018 to 2019.[10][13] During 2014, he held a visiting scientist position at Hokkaido University, Japan.

Koll has made contributions to understanding the rapid warming of the Indian Ocean, and how this warming is driving changes in the monsoon, the marine ecosystem, and increasing the frequency of extreme weather events across the region.[14][15] He has referred to the Indian Ocean as a "canary in a coal mine," suggesting that the climate change and extreme weather events occurring there serve as a warning for the future of all oceans, if urgent action is not taken.[16][17] His work has shown that the expansion of the Indo-Pacific Warm Pool is altering global rainfall patterns by modulating the Madden–Julian oscillation, which impacts weather systems across the tropics and beyond.[18][19][20]

Koll has been involved in the United Nations World Climate Research Programme's CLIVAR Project. He was the co-chair of the CLIVAR Indian Ocean Region Panel during 2018 to 2023 and played a role in redesigning the Indian Ocean Observing System to better understand and forecast the weather and climate for the nations surrounding the Indian Ocean.[5][21][22] He played a role in developing India's first Earth System Model and has been a lead author for the IPCC reports.[1][6]

Awards

[edit]

Koll received a National Academy of Sciences (NAS) Kavli Fellowship in 2015. In 2016 his research on the impact of climate change on the monsoon earned him the Indian Meteorological Society's Young Scientist Award.[12] In 2018 he was awarded the National Research Council (NRC) Senior Research Associateship of the US National Academy of Sciences.[12]

In December 2022 the American Geophysical Union (AGU) awarded him the AGU Devendra Lal Medal for scientists in developing countries in recognition of his research in Earth sciences and conferred him as an AGU Fellow.[5][23][24][25]

In August 2024, Koll was one of 18 scientists awarded the Rashtriya Vigyan Puraskar, a national science award presented by the President of India, in recognition of his contributions to climate science.[1][2][26]

Impact and advocacy

[edit]

Koll's research has influenced national climate policies and disaster management strategies, especially in the Indian Ocean region. He actively communicates climate science through various media outlets, aiming to bridge the gap between science and society.[17][27] He has written for major Indian newspapers and magazines including Times of India, Hindustan Times, The Hindu, Malayala Manorama, and Frontline.[28][29][30][31] He is a regular guest at TV and radio discussions about global warming and extreme weather events over South Asia.[32][33]

Koll has advocated for the establishment of climate-equipped schools in Kerala, proposing that all schools be outfitted with weather stations to serve as local climate hubs for education and real-time weather monitoring.[24][34] This initiative aims to enhance disaster preparedness while fostering climate awareness among students and communities, contributing to local resilience in the face of extreme weather events.[3][34][35] Koll was honored as a "Change Maker" at the Manorama News Conclave 2024, recognizing his impact on climate resilience and community engagement in Kerala.[36]
