Polar Studies – Window to the changing Earth

The polar regions are a critical component of the global climate system, with changes taking place at high latitudes having global implications. Anthropogenic activity is affecting both the Arctic and Antarctic, but the two polar regions are responding in very different ways, which complicated the separation of the anthropogenic signal from natural variability. The contributed articles in this issue describe polar scientific studies from various national and international research organizations. The studies are largely confined to understanding the ocean-atmospheric sciences, paleoclimatic conditions and biogeochemical processes in the polar and surrounding ocean realms. This special issue on “Polar Studies - Window to the changing Earth” presents high-quality and topical scientific research concerned with both polar regions. It is an initiative to commemorate the four decades of India's activities in polar research and its international scientific collaborations. In addition, it coincides with the completion of 75 years of India's Independence being celebrated as “Azadi Ka Amrit Mahotsav (Elixir of Freedom Festival)” and the holding of the first SCAR Open Science Conference in India, August 2022.
