Page 2-15 - Precipitation Increase (probable). As the climate warms, the increased poleward penetration of warm, moist air should increase the average annual precipitation in high latitudes. Rise in Global Mean Sea Level (probable). A rise in mean sea level is generally expected due to thermal expansion of seawater in the warmer future climate.
Page 2-15 - ... latitudes. Rise in Global Mean Sea Level (probable) . A rise in mean sea level is generally expected due to thermal expansion of sea water in the warmer future climate. Far less certain is the contribution due to melting or calving of land ice.
Page 2-15 - Warming (likely in the long term) Several studies have predicted a marked long-term drying of the soil moisture over some midlatitude interior continental regions during summer. This dryness is mainly caused by an earlier termination of snowmelt and rainy periods, and an earlier onset of the spring-tosummer reduction of soil wetness. Of course, these simulations of...
Page 1-2 - Following the hearings, committee members sent a formal request to the EPA Administrator, asking the Agency to undertake two studies on climate change due to the greenhouse effect. One of the studies we are requesting should examine the potential health and environmental effects of climate change. This study should include, but not be limited to, the potential impacts on agriculture, forests, wetlands, human health, rivers, lakes, and estuaries, as well as other ecosystems and societal impacts.
Page 2-15 - Global mean precipitation increase (very probable). Increased heating of the surface will lead to increased evaporation and therefore to greater global mean precipitation. Despite this increase in global average precipitation, some individual regions might well experience decreases in rainfall.
Page 2-15 - Despite this increase in global average precipitation, some individual regions might well experience decreases in rainfall. Reduction of sea ice (very probable). As the climate warms, total sea ice is expected to be reduced. Polar winter surface warming (very probable). As the sea ice boundary is shifted poleward, the models predict a dramatically enhanced surface warming in winter polar regions. The greater fraction of open water and thinner sea ice will probably lead to warming of the polar surface...
Page 2-15 - Large Stratospheric Cooling (virtually certain). Reduced ozone concentrations in the upper stratosphere will lead to reduced absorption of solar ultraviolet radiation and therefore less heating. Increases in the stratospheric concentration of carbon dioxide and other radiatively active trace gases will increase the radiation of heat from the stratosphere. The combination of decreased heating and increased cooling will lead to a major lowering of temperatures in the upper stratosphere.

Page 4-7 - ... is the significant factor. I think perhaps there are now some additional disciplines and factors that could be programed which could not have been programed a few years ago. Dr. Kaufman: In this area we do have mathematical models of the polluted streams. We do have, or have had, an analog model of the delta at the confluence of the Sacramento and San Joaquin Rivers. We have now another analog CONFERENCE ON SPACE, SCIENCE, AND URBAN LIFE model of the sizable watershed on the North Platte involving...
