It is well-known that HCFC refrigerants widely used in today’s air conditioning and refrigeration (AC&R) industry will soon be phased out, mainly due to their ozone depletion potentials (ODPs) and global warming potentials (GWPs). The timetable established through international agreement and national legislation calls for a 65% reduction of HCFC consumption based on 1989 level by January 1, 201...

Soil redox potential (Eh), concentrations of oxygen (O2) and three greenhouse gases (CO2, CH4, and N2O) were measured in the soil profile of a coastal forest at ridge, transition, and swamp across a hydrological gradient. The results delineated a distinct boundary in soil Eh and O2 concentration between the ridge and swamp with essentially no overlap between the two locations. Critical soil Eh ...

The more the various dimensions of climate change are just, the more an international agreement is in principle attainable. That is the reason why justice plays a major role in favouring collective action against global warming. In this article I spell out the dominant notions of justice and the consequent criteria of equity for the main domains of global warming negotiations, in order to ident...

Problem statement: Global warming is one of most significant factors affecting the biological evolution and the influenza is the disease that threatens humans with possible epidemics or pandemics. It would be important to understand if the global warming would have potential impact on the evolution of influenza virus. For this aim, the first would be to study the trend of evolution of proteins ...

. introduction the siberian high (sh) is a quasi-stationary and semi-permanent surface high pressure system residing over the eurasian continent during winter with its climatological–mean central pressure exceeding 1030 hpa. this most important atmospheric center of action controls the climate of a wide area of this continent. the sh forms generally in october mainly in response to strong radia...

gradual increase of the earth's surface temperature can cause many significant changes on the climate of our planet. this problem is progressively increasing. one of the main reasons for this phenomenon is the absorption of the sun's energy and lack of proper reflection of emissions due to man-made activities, one of which is the increase in black surfaces. in this descriptive and cross-section...
