Greenhouse Gas

During the last glacial-interglacial cycle, northern hemispheric (NH) ice-sheets experienced dramatic changes in radiative forcing, due to orbitally-driven insolation changes and varying greenhouse gas concentrations. This direct forcing caused temperature changes and eventually ablation anomalies. Orbital-scale variations in the atmospheric circulation caused anomalies in temperature advection and precipitation/snowfall that also strongly contributed to the mass balance and hence the time-evolution

The rapid economic growth and the depleting fossil fuels direct the Indian economy towards renewable energy sources. Among the renewable, the most sought after technologies are nuclear energy and solar energy. The paper compares nuclear energy to solar energy to choose a more viable option, given the abundant incident solar flux. Also, the paper proposes a negative green taxation regime to aid replace the solar panels after their lifetime.

Today, over-consumption, pollution and resource depletion threaten sustainability. Waste management policies frequently fail to reduce consumption, prevent pollution, conserve resources and foster sustainable products. However, waste policies are changing to focus on lifecycle impacts of products from the cradle to the grave by extending the responsibilities of stakeholders to post-consumer management. Product stewardship and extended producer responsibility are two policies in use, with radically different results when compared for one consumer product, refrigerators. North America has enacted product stewardship policies that fail to require producers to take physical or financial responsibility for recycling or for environmentally sound disposal, so that releases of ozone depleting substances routinely occur, which contribute to the expanding the ozone hole. Conversely, Europe's Waste Electrical and Electronic Equipment (WEEE) Directive requires extended producer responsibili...

... In addition, waste glass seemed to positively contribute to the mortar micro-structural properties resulting in an evident improvement of its mechanical performance [Corinaldesi et al. 2005a]. Mixed colored glass can be utilized in flowable self-compacting slurry or concrete [Naik ...

At the present stage, economic research on climate change and its main problem requires in-depth scientific study and analysis of various factors. An important source of air pollution is the energy sector, especially solid and liquid fuels used for technological purposes in thermal power plants. In Georgia, 1/5 of the total electricity generated is produced in thermal power plants. The article analyses Greenhouse gas emissions in Georgia by sectors and sub-sectors as well the criteria for estimating fuel combustion, such as net calorific value of fuel and carbon content standard indicators. The formula for calculation of CO2, CH4 and N2O emissions from the transport vehicles is developed in this work.

Anaerobic digestion is an appropriate technique for the treatment of sludge before final disposal and it is employed worldwide as the oldest and most important process for sludge stabilization. In general, mesophilic anaerobic digestion of sewage sludge is more widely used compared to thermophilic digestion. Furthermore, thermal pre-treatment is suitable for the improvement of stabilization, enhancement of dewatering of the

This article argues that, except in California, environmental justice considerations have not received sufficient attention in climate change policy debates. It explores the environmental justice implications of emerging domestic climate change policies and provides policymakers with specific suggestions on how to integrate environmental justice concerns. The article begins by introducing the environmental justice movement and its central principles, and then
