The Strategic Plan for the U.S. Climate Change Science Program (CCSP 2003) calls for the preparation of 21 synthesis and assessment products. Noting that “sound, comprehensive emissions scenarios are essential for comparative analysis of how climate might change in the future, as well as for analyses of mitigation and adaptation options,” the Plan includes Product 2.1, Scenarios of Greenhouse G...

Seasonally dry forests in the neotropics are heavily threatened by a combination of human disturbances and climate change; however, the severity of these threats is seldom contrasted. This study aims to quantify and compare the effects of deforestation and climate change on the natural spatial ranges of 17 characteristic tree species of southern Ecuador dry deciduous forests, which are heavily ...

This paper aims to explore the analysis of climate patterns embedded in the Global Climate Data Sets generated by the Community Climate System Model (CCSM) for the 4 Assessment Report of the Intergovernmental Report for Climate Change (IPCC). A Geographic Information Systems (GIS) approach is taken to examine spatiotemporal correlates among climate processes and to draw insights into their rela...

The Central Valley of California is one of the most important regions for wintering waterbirds in North America despite extensive anthropogenic landscape modification and decline of historical wetlands there. Like many other mediterranean-climate ecosystems across the globe, the Central Valley has been subject to a burgeoning human population and expansion and intensification of agricultural an...

Results As expected, all the three factors, propagule pressure, climate suitability and host availability, significantly explained quarantine arthropod invasions in Europe, but the propagule pressure only had a positive effect on invasion success when considered together with climate suitability and host availability. Climate change according to the A1F1 scenario generally increased the climate...

Climate change due to increasing the concentration of greenhouse gases (especially CO2) in the atmosphere causes changes in the rainfall regime, runoff rate, wind speed and solar radiation of atmosphere. In the present research, the maximum and minimum temperature parameters were simulated during the base period of 1979-2088 and two future periods of 1979-2070 and 2070-2090 using daily ...

The country's economy is dependent on many variables that play a role in growth and development of the country. There are many variables in the economy that effect on country's economy. On the other hand rainfall is one of important factor of climate change that affected on economic strategic programs such as agriculture sector programs. Rainfall Changes effect on many economic variables that i...
