At Climate Research Lab we focus on research and development that contributes to the science, monitoring, forecasts, and climate projections for South Asia and the larger Indo-Pacific region. We attempt to translate climate science to facilitate the food, water, and economic security of the region. The lab works on the mechanisms and impacts of climate change on the monsoon, cyclones, heat waves, the marine ecosystem, and human health. Future Indian Ocean How does the future Indian Ocean look like? The tropical Indian Ocean underwent basin-wide warming during the last 150 years (1871–2020). The warming in the Indian Ocean was strongest during the last seven decades, at a rate of 1.2°C per century. This is dwarfed by the projected warming of 3.8°C per century in the future, if emissions continue at the current rate. Is ocean warming pushing it into a permanent marine heatwave state? What is the extend of the warming, and what are the potential impacts? In this new article titled ‘Future projections for the tropical Indian Ocean’, we summarize our current understanding of the past and future changes in the physical and biogeochemical state of the Indian Ocean.

Dr. Koll reminded that because of climate change, heatwaves are here to stay and will intensify in the years to come. Based on an identification of regional hotspots from IMD’s maps, he argued for the development of a national heat management framework targeted at heat-prone districts. He also highlighted how temperatures can fluctuate throughout the day and the need for policymakers to consider steadily warming night-time temperatures because warm nights make recuperation difficult. Critical Gaps in the Indian Ocean Observing System The Indian Ocean Observing System collects high resolution ocean and atmospheric data, used for forecasting weather and climate events, such as cyclones, storm surges, rains and floods, heatwaves and droughts. Lack of deployment and maintenance of these ocean observation systems during the three years of COVID (2020-2022) resulted in an irrecoverable gap in our climate data and repercussions on our weather forecasts. Our new paper here, published in the Bulletin of the American Meteorological Society , quantify the critical gaps in the Indian Ocean Observing System (IndOOS), their potential impacts on weather and climate services, and provide recommendations for the way forward [ pdf ]. Gone with the Heat Gone with the Heat”, an embroidered story of coral reef bleaching under marine heatwaves. Marine heatwaves, extremely warm waters in the ocean, strip off the colorful protective membrane of the corals, bleaching and killing them. As corals die, the marine biodiversity and fishes depending them also disappear, making our oceans an ecological desert. Artwork executed by the Kolls and exhibited @ the International Indian Ocean Science Conference 2024, Lombok, Indonesia. Hawksbill turtles are critically endangered sea turtles. They feed on sea sponge, kelp and sea grass. Marine heatwaves bleach the sponges, wither the kelp and grass — and the sea turtles disappear… The coral and the marine species in the artwork are from the Indian Ocean region and found in the coral triangle. The artwork is hand embroidery by Juby Aleyas Koll (Sarah) on canvas, along with water color, acrylic, beads, and sand from the Indian Ocean. Each coral and fish species are depicted with different hand embroidery stitches. COP28: The Gulf between Climate Commitments and Reality Op-Ed on COP28 in The Times of India, December 2023 [ pdf ] There is a huge gulf” between IPCC science and the COP28 consensus. Global warming already exceeds 1.2°C and will surpass 1.5°C by 2030 and 2°C by 2050, as the trajectory of emissions and COP28 commitments to curb them are insufficient in restraining the temperature rise. COP28 came out with a pledge of $792 million for the loss and damage climate fund. The pledged amount is less than 1% of the losses developing countries face every year from global warming, which is at the scale of several trillion dollars. International Indian Ocean Expedition If you use weather forecasts, thank the monitoring systems in the ocean and the research and modeling that support these forecasts …and the people behind them! Recently, we conducted a brainstorming on the Future Road Map for the International Indian Ocean Expedition (IIOE2) at the I ndian National Center for Ocean Information Services (INCOIS) , Hyderabad. The 2nd International Indian Ocean Expedition is a major global scientific program engaging the international scientific community in collaborative oceanographic and atmospheric research from coastal environments to the deep sea over the period 2015-2025, revealing new information on the Indian Ocean (i.e. its currents, its influence upon the climate, its marine ecosystems) which is fundamental for...
