Environmental Effects of Ozone Depletion: 1994 Assessment

Description: A change in the composition of the stratosphere becomes relevant to society only if it has noticeable effects. This places the assessment of effects in a pivotal role in the problem of ozone depletion. Decreases in the quantity of total-column ozone, as now observed in many places, tend to cause increased penetration of solar UV-B radiation (290-315 nm) to the Earth's surface. UV-B radiation is the most energetic component of sunlight reaching the surface. It has profound effects on human healt… more

The Terrestrial Biosphere and Global Change: Implications for Natural and Managed Ecosystems

Description: From the perspective of terrestrial ecosystems, the most important component of global change over the next three or four decades will likely be land-use/cover change. It is driven largely by the need to feed the expanding human population, expected to increase by almost one billion (109) people per decade for the next three decades at least. Much of this increase will occur in developing countries in the low-latitude regions of the world. To meet the associated food demand, crop yields will ne… more

Potential for Accelerated Bioremediation and Restoration of Oil-Impacted Marshes through the Selection of Superior Oil-Tolerant Vegetation

Description: Report describing a study of the genotypes two plants (Spartina Patens and Spartina Alterniflora) that are tolerant to oil spills that have occurred in the coastal marshes of Louisiana. The research was to determine if these two plants could utilized for restoration and bioremediation of areas effected by oil spills. A plants tolerance to oil is determined by three factors: growth response and plant production, superior vegetative regrowth in soil effected by oil, and superior oil degradation p… more

Climate Change and Extreme Weather Events

Description: The report of the Intergovernmental Panel on Climate Change of 1995 has been taken as a starting point. Since 1995 many new observations and reports have become available. Much of the information on observations and studies on climate change and its impacts can be found through the Internet. Where possible we have made references, such that the reader can easily verify and review our sources. This study addresses three main questions: To what extent can the human influence on the climate system… more
