The objective of this report is to illustrate insights into alternative policy options and the potential impact nationally and explicitly at the state level associated with a modest GHG control policy. Differences in the structure of the economy across the United States are likely to cause these impacts to diverge from those estimated for the country as a whole.

Destruction of the Earth's ozone shield due to the release of hydrogen sulphide and methane has been suggested as a cause of mass extinctions during periods of ocean anoxia over the past two billion years. This mechanism does not explain the end-Permian mass extinction, according to simulations with a two-dimensional atmospheric chemistry-transport model, which show that the ozone shield remains intact even with massive releases of hydrogen sulphide and methane.

In an era of unabated and unplanned development, there is greatest possibility of the environment being irreversibly affected. One such crisis which has created a worldwide impact in global warming. With a sudden rise in temperatures throughout the world, climates have changed drastically, endangering the existence of each and every life form on earth. Here we look into climate change issues related to India.

Black carbon in soot is the dominant absorber of visible solar radiation in the atmosphere. Anthropogenic sources of black carbon, although distributed globally, are most concentrated in the tropics where solar irradiance is highest. Black carbon is often transported over long distances, mixing with other aerosols along the way. The aerosol mix can form transcontinental plumes of atmospheric brown clouds, with vertical extents of 3 to 5 km.

The Gateway of India will be wiped off the Mumbai skyline. Bhelpuri at Chowpatty will become the stuff of grandmother's tales. No flights will take off from Chhatrapati Shivaji airport.

Changing climate patterns can lead to disastrous health impacts, especially in developing countries like India, a leading scientist has warned, and urged governments and policy makers to pay more atte

power of the big Banana: A court of appeals in the Philippines recently sided with the banana growers and exporters of the country and allowed the continuation of aerial spraying of pesticides. The

Global warming may spell doom for some of the Orissa's heritage sites, including Puri's Jagannath temple and Konark Sun temple, according to a recent Greenpeace report.

Earth Hour (8 pm to 9 pm) may have gone unobserved in many parts of the State on Saturday, but not for Aaron Pereira, a first year BA student residing at Fontainhas in Panjim.

A new technique for deriving hurricane climatologies from global data, applied to climate models, indicates that global warming should reduce the global frequency of hurricanes, though their intensity may increase in some locations.

Tropical cyclones account for the majority of natural catastrophic losses in the developed world and, next to floods, are the leading cause of death and injury among natural disasters affecting developing countries (UNDP/BCPR 2004). It is thus
of some interest to understand how their behavior is affected by climate change, whether natural or anthropogenic.
