Focuses on the climatology of an eight-state region in the southern and southeastern United States. Discusses general controls of climate and spatial patterns of various climatic averages. Examines mapped extremes as a means of fostering increased awareness of the variability that exists for climatic conditions in the region. (CMK)

The International Antarctic Glaciological Project has collected information on the East Antarctic ice sheet since 1969. Analysis of ice cores revealed climatic history, and radar soundings helped map bedrock of the continent. Computer models of the ice sheet and its changes over time will aid in predicting the future.

"Nuclear Winter" was recently coined to describe the climatic and biological effects of a nuclear war. These effects are discussed based on models, simulations, scenarios, and projections. Effects on human populations are also considered. (JN)

Discusses a theory suggesting that large-scale extinctions of marine animal families occur in cycles of 26 million years. Research methodology consisted of analyzing and charting fossil records showing the decline and disappearance of these animals over the past 250 million years. Other theories are considered. (BC)

The design of any solar heating system is influenced heavily by climate; in this bulletin, information on climate as related to solar heating is as related to solar heating is provided. Topics discussed include: (1) solar radiation; (2) degree days; (3) climate and calculations which make use of solar radiation and degree days; and (4)…

Discusses conflicting theories that explain how and why bombardment by comets spells periodic disaster for life on earth. Dislodgment of comets occurs from a vast cloud that envelops the solar system by gravitational forces of either a companion star of the sun or a dust cloud. (BC)

Examines samples of southern literature from the first half of the century that can be used to understand, geographically, the rural landscapes of the Coastal Plain from North Carolina through Mississippi. Addresses the socioeconomic imprint upon the land, climatic perceptions, and the role of the forest in literary works. (CMK)

The chemistry of the ocean, whose constituents interact with those of air and land to support life and influence climate, is known to have undergone changes since the last glacial epoch. Changes in dissolved oxygen, calcium ions, phosphate, carbon dioxide, carbonate ions, and bicarbonate ions are discussed. (JN)

Presents direct and indirect causes of erosion in developing countries. Identifies soil conservation developments ranging from major international policy reforms to small-scale, local farming programs. Suggests that strategies at all levels, and the political will to implement them, are needed if erosion is to be reduced to a sustainable rate. (23…

Scientists and educators examined long-term national and world trends related to the web of interrelationships involved in climate, food production, population, land use, and environmental quality. Current information and projections for the next quarter century were discussed. In reviewing scientific findings, it was noted that global weather…

Explores the Columbia River Basin, its ecosystems, and challenges faced by natural resource managers. By studying the basin's complexity, students can learn about common scientific concepts such as the power of water and effects of rain shadows. Students can also explore social-scientific issues such as conflicts between protecting salmon runs and…
