The risks of climate change resulting from the increase in atmospheric concentration of greenhouse gases have been well-documented. There are likely to be especially adverse effects on developing countries and particularly the poor within these countries. There is a global consensus that strong actions need to be taken to ensure that the world does not face excessive risk from an increase in th...

Observations indicate that the height of the tropopause-the boundary between the stratosphere and troposphere-has increased by several hundred meters since 1979. Comparable increases are evident in climate model experiments. The latter show that human-induced changes in ozone and well-mixed greenhouse gases account for approximately 80% of the simulated rise in tropopause height over 1979-1999....

The U.S. generates more than 37 million metric tons of food waste each year, and over 95% of it is disposed of at U.S. landfills. This paper describes the development of a novel food waste collection kiosk and business model called “Greenbox” that will collect and store food waste from households and restaurants with incentives for user participation to spur food waste-to-energy production in a...

A transition from the global system of coal-based electricity generation to low-greenhouse-gas-emission energy technologies is required to mitigate climate change in the long term. The use of current infrastructure to build this new low-emission system necessitates additional emissions of greenhouse gases, and the coal-based infrastructure will continue to emit substantial amounts of greenhouse...

We present the detection of the signatures of land use/land cover (LULC) changes on the regional climate of the US High Plains. We used the normalized difference vegetation index (NDVI) as a proxy of LULC changes and atmospheric CO2 concentrations as a proxy of greenhouse gases. An enhanced signal processing procedure was developed to detect the signatures of LULC changes by integrating autoreg...

Environmental issues have become increasingly important in the political arena, particularly with growing concern over the "greenhouse effect", a potential global climatic warming caused by increases in anthropogenic emissions of greenhouse gases. The United States alone accounts for 25% of the worldwide emissions of C02, the most important of the greenhouse gases. The generation of electric po...
