Abstract: Solar variability models which account for contemporary irradiance variations in terms of modulation by dark sunspots and bright faculae on the solar disk are used to estimate solar radiative output during the Maunder Minimum by postulating the absence of such sources, and additional reduction in the basal solar emission. When the resultant irradiance reduction of 0.25% relative to contemporary mean levels is input to the GISS GCM, the global mean temperature is reduced by 0.46°C. However, as a result of differential heating of the land and oceans, some regions may cool, and others warm, by as much 1°C, in response to the reduced solar irradiance.

Abstract: The development of realistic climate change scenarios requires consideration of the range of potential feedbacks between the atmosphere, the oceans, and the land surface. Such an understanding is essential in order to adequately describe natural climate variability and man-made climate change, as well as the uncertainty in their ability to represent the physical and biogeochemical process in the modeling of climate. There are serious misconceptions, however, regarding the use of models to estimate climate change. First, general circulation models (GCMs) are not global climate models, and although ocean feedbacks have begun to be included in GCMs, current state-of-the-art GCMs are incomplete tools to be used to represent the entire spectrum of potential climate change. The GCMs provide only a subset of possible future climate conditions and represent sensitivity experiments, not prebiogeophysical feedbacks that are sufficiently nonlinear.

Abstract: Anthropogenic emissions of carbon dioxide and other "greenhouse" gases have the potential to substantially warm climates worldwide While the timing and magnitude of global warming is uncertain, scientists on the Intergovernmental Panel on Climate Change (IPCC) predict that average global temperature may increase by 15- 45³C (27-81³F) over the next 100 years Changes in precipitation will likely accompany any changes in temperature However, the magnitude, and even direction of these changes is difficult to predict with much confidence on a regional basis The agricultural sector may be profoundly affected by future changes in temperature, precipitation, solar radiation, and carbon dioxide concentrations Over the past decade, there has been a growing body of research examining the potential impacts of climate change on agriculture The purpose of this paper is to report and summarize recent research on the potential economic impacts of global climate change on agriculture To that end, an annotative bibliography of articles is presented in this paper

Abstract: The question of global climate change has been a major item on the political agenda for several years now. Politically, the main concern has been the impact of anthropogenic increases in minor greenhouse gases (the major greenhouse gas is water vapor). The question is also an interesting scientific question. Restricting ourselves to issues of climate, the answer requires that we be able to answer at least two far more fundamental questions, both involving strong fluid mechanical components:
