Climate Change And Geodynamics In Polar Regions

"Climate Change and Geodynamics in Polar Regions covers most of the scientific aspects of geoscientific investigation undertaken by Indian researchers in the Polar Regions: Antarctic, Arctic, and Himalayan regions. A firm understanding of the cryosphere region's geological perspectives helps students and geoscientists evaluate important scientific queries in the field. It will help readers understand how the cryosphere's geoscientific evolution took place in the geological past, climate change throughout history, and how Polar Regions were affected by global warming. It also discusses how we might expect Polar climate to change in the future. A firm understanding of the cryosphere region's geological perspectives helps students and geoscientists answer some of the most puzzling scientific queries and generate new ideas for future research in this field"--

Comprehensive, up-to-date account of polar climate change over the last one million years for researchers and advanced students in polar science.

The polar regions are experiencing rapid changes in climate. These changes are causing observable ecological impacts of various types and degrees of severity at all ecosystem levels, including society. Even larger changes and more significant impacts are anticipated. As species respond to changing environments over time, their interactions with the physical world and other organisms can also change. This chain of interactions can trigger cascades of impacts throughout entire ecosystems. Evaluating the interrelated physical, chemical, biological, and societal components of polar ecosystems is essential to understanding their vulnerability and resilience to climate forcing. The Polar Research Board (PRB) organized a workshop to address these issues. Experts gathered from a variety of disciplines with knowledge of both the Arctic and Antarctic regions. Participants were challenged to consider what is currently known about climate change and polar ecosystems and to identify the next big questions in the field. A set of interdisciplinary "frontier questions" emerged from the workshop discussions as important topics to be addressed in the coming decades. To begin to address these questions, workshop participants discussed the need for holistic, interdisciplinary systems approach to understanding polar ecosystem responses to climate change. As an outcome of the workshop, participants brainstormed methods and technologies that are crucial to advance the understanding of polar ecosystems and to promote the next generation of polar research. These include new and emerging technologies, sustained long-term observations, data synthesis and management, and data dissemination and outreach.

Surveys atmospheric, oceanic and cryospheric processes, present and past conditions, and changes in polar environments.

The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. The volume addresses the following major topics: - Research results in observing aspects of the Arctic climate system and its processes across a range of time and space scales - Representation of cryospheric, atmospheric, and oceanic processes in models, including simulation of their interaction with coupled models - Our understanding of the role of the Arctic in the global climate system, its response to large-scale climate variations, and the processes involved.

This book showcases the results of studies pertaining to climate changes in the Polar Regions - Arctic-Antarctic-Himalaya. It discusses the significant variations due to thinning of sea ice in the Arctic, insights on the first Indian Arctic multi-sensor mooring (IndARC), political context of major geological and tectonic features of Arctic Ocean, climate change and its predicted impacts on fisheries and coastal communities. The book also contains the work pursued under the National Mission for Sustaining the Himalayan Ecosystems, aiming towards strengthening the capacities of farmers through appropriate Lab-to-Land intervention to combat climate change issues. Discussions on various models like WRF (Weather Research and Forecasting), Regional Climate Model (RegCM4) pertaining to Himalaya have been highlighted to gain more insights on climate change.
