NCPOR Shines at the Arctic Science Summit Week

By

 The Arctic Science Summit Week (ASSW) was held in Vienna, Australia in February in 2023. The National Centre for Polar and Ocean Research (NCPOR) participated in the event displaying its commitment to advancing scientific research in the polar and ocean sciences, and its contribution to better understanding and addressing the impacts of climate change. The session led by NCPOR in ASSW focused on the causes and effects of changes in Arctic sea ice on weather and climate in lower latitudes was much appreciated. It provided valuable insights into the current state of knowledge on this topic and highlighted the need for further research.

The Arctic Science Summit Week (ASSW) is an annual event organised by the International Arctic Science Committee (IASC) to foster collaboration and coordination among scientific organisations involved in Arctic research. In odd number years, the ASSW includes a Science Symposium. These symposia create a platform for exchanging knowledge, cross-fertilization and collaboration of scientists, students, policymakers and other professionals from all over the world. In even number years, the ASSW includes the Arctic Observing Summit (AOS), a high-level, biennial summit that aims to provide community-driven, science-based guidance for the design, implementation, coordination and long-term operation of Arctic observing systems. This year's event, ASSW 2023 Science Symposium, was held in Vienna, Austria from February 17-24, 2023.

Session on Arctic Sea-Ice Changes by NCPOR

During the Science Symposium, one of the sessions held was titled Arctic sea ice changes: Causes and their effect on weather and climate in lower latitudes,  was chaired by Dr Avinash Kumar, a scientist from the National Centre for Polar and Ocean Research (NCPOR), Ministry of Earth Sciences Goa, India and co-chaired by Dr Rohit Srivastava, Scientist NCPOR and Prof Seong-Joong Kim, Principal Scientist, Korea Polar Research Institute. The open session was held in a Hybrid mode and a total of 11 presentations were delivered in this session, out of which five were from NCPOR on the topics: Role of lower atmosphere air temperature on decadal sea-ice variability in the Arctic; Influence of Arctic Sea Ice Extent on South Asian Monsoon during Mid-Piacenzian Warm Period; Arctic to tropics, whether a two-way teleconnection mechanism exists; Investigation of aerosols properties over the Arctic region using a regional climate model; Possible linkages between spring Arctic Sea ice and Indian summer monsoon rainfall. The rest of the presentations in this session were from Indian Institute of Tropical Meterology (IITM), Indian institute of Technology Kharagpur, Norwegian Meteorological Institute, Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research and University college, London. NCPOR's participation in the ASSW reflects the institution's commitment to advancing scientific research in the polar and ocean sciences and its contribution to better understanding and addressing the impacts of climate change. The session aimed to explore observational and model-based studies on Arctic ocean-atmosphere processes and their teleconnection with lower latitudes.

The session focused on the causes and effects of changes in Arctic sea ice on weather and climate in lower latitudes. It aimed to bring together researchers working on various aspects of Arctic science to exchange ideas and share their findings. There were around fifteen oral and poster presentations covering various topics, including the role of Scandinavian blocking in Arctic-mid latitude linkages, the impact of lower atmosphere air temperature on Arctic sea-ice variability, and the creation of the MISR Arctic and Antarctic Sea Ice Albedo 2000-2022 product. Other presentations included research on the relationship between the Azores High and the Indian summer monsoon, Arctic sea ice's influence on the South Asian monsoon during the Mid-Piacenzian warm period. Additionally, possible linkages between spring Arctic sea ice and Indian summer monsoon rainfall and investigation on aerosol properties over the Arctic region using a regional climate model were presented. The session highlighted the interconnected nature of the global climate system and the importance of studying the Arctic region as a key component of this system.

 Outcomes

Overall, the session was successful in bringing together experts from various fields across the world to discuss the complex and pressing issues related to Arctic sea ice changes and their impacts on lower latitudes. The discussions and presentations provided valuable insights into the current state of knowledge on this topic and highlighted the need for further research to understand and mitigate the impacts of Arctic sea ice changes on the global climate system.

India is set to host the 46th   Antarctic Treaty Consultative Meeting in 2024 at Kochi, Kerala. Experts view this meeting as crucial for the future of Antarctic Climate Change and tourism. Besides, the expiration of the Antarctic Treaty in 2048 is another area of concern for both policy-makers and the scientific community. As a Consultative Party to the Antarctic Treaty, the ATCM 46 holds great significance for India from both environmental and strategic perspectives. Introduction The recently concluded XLV  Antarctic Treaty Consultative Meeting (ATCM45)  held at Helsinki focused on the  urgency of climate action. Climate change is one of the greatest threats facing Antarctica. The sea level rise caused by melting ice sheets is concerning the scientists and policy-makers as its effects are being felt world over. Besides, maritime safety in the Polar regions, growing tourism and geopolitical interest in Antarctica were also the important focus areas of the Helsinki ATCM. As India is

How important is Earth (and Earth Science) to society?

The paper on which this article is printed, reading glasses, paste, blade, kitchen slab, spoon, plate,  tiles, cell phone, battery, car, petrol….. What is the common thread that passes through these diverse items? They all contain materials obtained from Mother Earth! This article, being published sometime after Earth Day (April 22), showcases the significance of the earth and earth science to humans. Geology is generally understood as a subject that deals with the study of rocks but it is much more than that. It deals with the study of solid earth, its structure and composition, and all the processes that go on beneath and on the earth’s surface. Today we know that Planet Earth is not just solid earth but is a system that includes the atmosphere, hydrosphere (all water bodies), and cryosphere (glaciers, ice caps, and sea ice) in which biosphere (plants, animals, and microbes, including humans) thrives. Therefore, we call this discipline not geology but Earth System Science ; the o

Rising Sea-level and its Sinking Consequences

By
Image
Sea level rise refers to the gradual increase in the water level of the earth’s oceans, primarily caused by the melting of glaciers and ice sheets, as well as the expansion of seawater as it warms due to climate change. This phenomenon has become a major concern in recent years due to its potential impacts on coastal communities, infrastructure, and ecosystems. Rising sea levels can result in increased coastal erosion, flooding, and storm surges, leading to displacement of people and loss of property. It also threatens critical infrastructure such as ports, airports, and power plants, and can impact marine ecosystems by altering the habitat of marine species. Sea level rise is a complex issue that requires urgent action to mitigate its effects and protect vulnerable communities and ecosystems.                                                                Image Source: Unsplash Sea level rise may be defiend as relative sea level change, considered as the change in the height of oceans
