Download or read book The Ocean and Cryosphere in a Changing Climate written by Intergovernmental Panel on Climate Change (IPCC) and published by Cambridge University Press. This book was released on 2022-04-30 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.
Download or read book New Perspectives on Blowing Snow in Antarctica and Implications for Ice Sheet Mass Balance written by Stephen Palm and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blowing snow processes commonly occur over the earth,Äôs ice sheets and snow covered regions when near surface wind speed exceeds a threshold value. These processes play a key role in the sublimation and redistribution of snow, thereby influencing the surface mass balance. Prior field studies and modeling results have shown the importance of blowing snow sublimation and transport on the surface mass budget and hydrological cycle of high latitude regions. Until recently, most of our knowledge of blowing snow was obtained from field measurements or modeling. Recent advances in satellite remote sensing have enabled a more complete understanding of the nature of blowing snow. Using 12¬†years of satellite lidar data, climatology of blowing snow frequency has been compiled, showing the spatial and temporal distribution of blowing snow frequency over Antarctica. Other characteristics of blowing snow such as backscatter structure and profiles of temperature, relative humidity, and winds through the layer are explored. A new technique that uses direct measurements of blowing snow backscatter combined with model meteorological reanalysis fields to compute the magnitude of blowing snow sublimation and transport is also discussed.

Book excerpt: Global snow and ice cover (the 'cryosphere') plays a major role in global climate and hydrology through a range of complex interactions and feedbacks, the best known of which is the ice - albedo feedback. Snow and ice cover undergo marked seasonal and long term changes in extent and thickness. The perennial elements - the major ice sheets and permafrost - play a role in present-day regional and local climate and hydrology, but the large seasonal variations in snow cover and sea ice are of importance on continental to hemispheric scales. The characteristics of these variations, especially in the Northern Hemisphere, and evidence for recent trends in snow and ice extent are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: It is argued that deformation of the ice canopy has been neglected in past computations and considerations of the mass budget of pack ice in the Arctic Ocean. Evidence is presented to indicate that in the Canadian Basin alone, 13 to 18 percent of the ice area is covered by pressure ice considerably thicker than the 6 to 14 feet usually considered the average thickness of polar ice. A geometrical model based on empirical observations of under-ice, surface, and subsurface features is offered to permit computations of the volume of sea ice contributed by pressure ice. This model suggests that 1:3.3 is a realistic ratio between the above-water and underwater portions of an ice pressure ridge. Seasonal and spatial data from two years of aerial surveys on the frequency and height of ridges are presented, showing maximal values in winter near the North American coastlines. Similar data are presented on ice concentrations, stage of ice development, and the distribution of open and refrozen water throughout the Arctic Basin. Extensive submarine echo sounding data on the frequency of ice of various thicknesses corroborate the existence of larger amounts of open water - 15 percent more in summer - than previously estimated over large portions of the Arctic Basin.

Research and Development Branch and published by Defence Research Establishment Pacific. This book was released on 1979 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The result of 18 year's record (1958-1976) of accumulation and ablation from the Ward Hunt ice rise and of 10 years record (1965-1976) from the Ward Hunt Ice Shelf are presented. The net mass balances on the ice rise for the years 1962-1965 and on both the ice rise and the ice shelf for 1972-1975 are positive. The net mass balances for all other years are negative. There is only fair correlation between the net ablation and the mean summer temperatures at Alert since the ablation rate is sensitive to several other factors, notably the surface albedo. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The climate record for the past 100,000 years clearly indicates that the climate system has undergone periodic-and often extreme-shifts, sometimes in as little as a decade or less. The causes of abrupt climate changes have not been clearly established, but the triggering of events is likely to be the result of multiple natural processes. Abrupt climate changes of the magnitude seen in the past would have far-reaching implications for human society and ecosystems, including major impacts on energy consumption and water supply demands. Could such a change happen again? Are human activities exacerbating the likelihood of abrupt climate change? What are the potential societal consequences of such a change? Abrupt Climate Change: Inevitable Surprises looks at the current scientific evidence and theoretical understanding to describe what is currently known about abrupt climate change, including patterns and magnitudes, mechanisms, and probability of occurrence. It identifies critical knowledge gaps concerning the potential for future abrupt changes, including those aspects of change most important to society and economies, and outlines a research strategy to close those gaps. Based on the best and most current research available, this book surveys the history of climate change and makes a series of specific recommendations for the future.
