Amid growing concerns about climate change and long-term petroleum reserves, the food system looms large as a major user of fossil fuels and, as a result, producer of greenhouse gases (GHG). Indeed, these twin problems may be the significant drivers that catalyze change in the food system in the 21 century. Already we are witnessing a stream of new policies aimed at reducing greenhouse gases, i...

Now in these days’ green house gases is the main cause of global warming and affects the climate in the world. Environmental arguments centre on the need to reduce greenhouse gases (GHGs) emissions for the sake of both the global and local climate, particularly in large cities. Excessive exploitation of natural resources for development has been resulted into many environmental problems like en...

There is considerable, if not conclusive, scientific evidence that the atmospheric accumulation of carbon dioxide, methane, and other "greenhouse" gases emitted through the combustion of fossil fuels will lead to major changes in the earth's climate, with important economic effects. The nations of the world have agreed at the Kyoto Conference in 1997 to put in place some system of economic ince...

This new regulation, under the Environmental Management Act, is anticipated to come into effect on January 1, 2009. The Environmental Management Act, brought into force in July 2004, is a key environmental statute in British Columbia. Amendments to the Act, currently before the Legislature, would provide enabling powers to regulate the management of greenhouse gases. The proposed Landfill Gas R...

1.Background of the Problem The global climatic warm-up is a common challenge facing mankind, and also one of the global ecological crises most concerned by mankind. Such concern has been fully reflected in the Framework Convention on Climatic Changes (FCCC) signed by more than 150 countries, and several negotiations afterwards. Meantime, in view of the ambiguity in the statements of the framew...

The increase in atmospheric greenhouse gas concentrations of CO2 and CH4, due to human activities, is the main driver observed surface temperature by more than 1 °C since pre-industrial era. At 2015 United Nations Climate Change Conference held Paris, most nations agreed reduce emissions limit global 1.5 °C. Satellite remote sensing CH4 now well established thanks missions such as NASA’s OCO-2 ...

The last decade has seen an unprecedented rise in greenhouse gases in the atmosphere mostly due to anthropogenic activities. In order to cutback on the greenhouse gas emissions we need to calculate accurately the greenhouse gas budget. The paper being reviewed here delineates a fine approach in that direction. The paper describes measurements from an old radio tower in Switzerland. Tall tower m...
