The high latitudes of the Arctic and Antarctic, together with some mountainous areas with glaciers and long-lasting snow, are sometimes called the cryosphere-defined as that portion of the planet where water is perennially or seasonally frozen as sea ice, snow cover, permafrost, ice sheets, and glaciers. Variations in the extent and characteristics of surface ice and snow in the high latitudes are of fundamental importance to global climate because of the amount of the sun's radiation that is reflected from these often white surfaces. Thus, the cryosphere is an important frontier for scientists seeking to understand past climate events, current weather, and climate variability. Obtaining the data necessary for such research requires the capability to observe and measure a variety of characteristics and processes exhibited by major ice sheets and large-scale patterns of snow and sea ice extent, and much of these data are gathered using satellites. As part of its efforts to better support the researchers studying the cryosphere and climate, the National Aeronautics and Space Administration (NASA)-using sophisticated satellite technology-measures a range of variables from atmospheric temperature, cloud properties, and aerosol concentration to ice sheet elevation, snow cover on land, and ocean salinity. These raw data are compiled and processed into products, or data sets, useful to scientists. These so-called "polar geophysical data sets" can then be studied and interpreted to answer questions related to atmosphere and climate, ice sheets, terrestrial systems, sea ice, ocean processes, and many other phenomena in the cryosphere. The goal of this report is to provide a brief review of the strategy, scope, and quality of existing polar geophysical data sets and help NASA find ways to make these products and future polar data sets more useful to researchers, especially those working on the global change questions that lie at the heart of NASA's Earth Science Enterprise.

Bold Endeavors: Lessons from Polar and Space Exploration presents the results of 15 years of research for NASA and the Department of Defense concerning the factors that contribute to adjustment and sustained human performance under conditions of isolation and confinement. The research involved the study of previous space operations and conditions on Earth, such as submarines, Antarctic stations, polar expeditions, and voyages of discovery, that are comparable to what might be expected for future long duration space missions. Bold Endeavors is read by students, engineers, behavioral scientists, modern explorers, and the personnel staffing US Antarctic stations, among others; it has been described as “required reading” for members of NASA’s Expedition Corps, astronauts who are preparing for expeditions to the International Space Station and beyond. Bold Endeavors is of interest to the fields of psychology, psychiatry, human factors and ergonomics, anthropology, aerospace engineering, space medicine, personnel selection, organizational management, and the history of exploration. The chapter on Food is even used as a reference in culinary and hospitality-management programs.

Providing clean water to earth's rapidly growing human population is one the major issues of the 21st Century. The climatic effects of global warming on water supply has made this a hot-button issue.

This guide provides coverage of the new tools available to predict and manage urban water supply demand. It provides methods for analyzing urban water demand, and techniques and software packages for optimally integrating planning and management activities.

The processes and consequences of climate change are extremely heterogeneous, encompassing many different fields of study. Dr David Rind in his career at the NASA Goddard Institute for Space Studies and as a professor at Columbia University has had the opportunity to explore many of these subjects with colleagues from these diverse disciplines. It was therefore natural for the Lectures in Climate Change series to begin with his colleagues contributing lectures on their specific areas of expertise.This first volume, entitled Our Warming Planet: Topics in Climate Dynamics, encompasses topics such as natural and anthropogenic climate forcing, climate modeling, radiation, clouds, atmospheric dynamics/storms, hydrology, clouds, the cryosphere, paleoclimate, sea level rise, agriculture, atmospheric chemistry, and climate change education. Included with this publication are downloadable PowerPoint slides of each lecture for students and teachers around the world to be better able to understand various aspects of climate change.The lectures on climate change processes and consequences provide snapshots of the cutting-edge work being done to understand what may well be the greatest challenge of our time, in a form suitable for classroom presentation.

The International Polar Years and the International Geophysical Year represented a remarkable international collaborative scientific effort that has been largely neglected by historians. This groundbreaking collection seeks to redress that neglect and illuminate critical aspects of the last 150 years of international scientific endeavour.
