Beyond mitigation : potential options for counter-balancing the climatic and environmental consequences of the rising concentrations of greenhouse gases

Global climate change is occurring at an accelerating pace, and the global greenhouse gas (GHG) emissions that are forcing climate change continue to increase. Given the present pace of international actions, it seems unlikely that atmospheric composition can be stabilized at a level that will avoid"dangerous anthropogenic interference"with the climate system, as called for in the UN Framework Convention on Climate Change. Complicating the situation, as GHG emissions are reduced, reductions in the offsetting cooling influence of sulfate aerosols will create an additional warming influence, making an early transition to climate stabilization difficult. With significant reductions in emissions (mitigation) likely to take decades, and with the impacts of projected climate change-even with proactive adaptation-likely to be quite severe over the coming decades, additional actions to offset global warming and other impacts have been proposed as important complementary measures. Although a number of possible geoengineering approaches have been proposed, each has costs and side effects that must be balanced against the expected benefits of reduced climate impacts. However, substantial new research is needed before comparison of the relative benefits and risks of intervening is possible. A first step in determining whether geoengineering is likely to be a useful option is the initiation of research on four interventions to limit the increasing serious impacts: limiting ocean acidification by increasing the removal of carbon dioxide from the atmosphere and upper ocean; limiting the increasing intensity of tropical cyclones; limiting the warming of the Arctic and associated sea level rise; and sustaining or enhancing the existing sulfate cooling influence. In addition, in depth consideration is needed regarding the governance structure for an international geoengineering decision-making framework in the event that geoengineering becomes essential.Montreal Protocol,Climate Change,Energy Production and Transportation,Energy and Environment,Environment and Energy Efficiency

Succession, Invasion, & Coexistence: PDEs in Ecology

We study the behavior of diffusive Lotka-Volterra systems in environments with spatially varying carrying capacities. In particular, we use numeric and analytic techniques to study two similar models for population growth, in order to determine their qualitative differences. Additionally, we investigate competition models in the presence of periodic disasters, in order to determine what factors affect competitive dominance. We found that under conditions of high spatial heterogeneity, the model for population growth was the main factor determining coexistence. Under low spatial heterogeneity, the effect of disturbance on the stronger competitor was the main factor determining coexistence

An Italian Complaint for the Death of Pierre de Lusignan

The death of Pierre Ier de Lusignan, King of Cyprus and Jerusalem, on the I6th of January, 1369, aroused the fear and horror of Christendom as few assassinations have done. The poem of Nicolò di Scacchi which is here printed, I believe for the first time, is one of several efforts to portray in literature the genuine consternation roused not only in Italy, but in France and England as well, by the loss to the Christian powers of so staunch a defender of the faith

The challenge of identifying greenhouse gas-induced climatic change

Meeting the challenge of identifying greenhouse gas-induced climatic change involves three steps. First, observations of critical variables must be assembled, evaluated, and analyzed to determine that there has been a statistically significant change. Second, reliable theoretical (model) calculations must be conducted to provide a definitive set of changes for which to search. Third, a quantitative and statistically significant association must be made between the projected and observed changes to exclude the possibility that the changes are due to natural variability or other factors. This paper provides a qualitative overview of scientific progress in successfully fulfilling these three steps

Letter from Samuel F. MacCracken to James B. Finley

Finley had promised MacCracken that he would come to Lancaster Station for a visit. It has been two months and nothing has been planned. MacCracken and Rev. Granville Moody are growing impatient and make one more request that Finley come. You was the pioneer that first organized this church. I now trust you will make some sacrifice for our spiritual good. Abstract Number - 346https://digitalcommons.owu.edu/finley-letters/1544/thumbnail.jp
