Zero CFC emission by 2010 Retrofitting workshop in Thimphu
Bhutan, in compliance with the Vienna convention for protection of ozone layer and the Montreal protocol, will have to cut chlorofluorocarbon (CFC) to zero percent by 2010. According to the national ozone officer of the national environment commission (NEC) secretariat, Peldon Tshering, Bhutan had already phased out 85 percent CFC of the baseline.

Every short flight trip responsible for increase in carbon emission'
Inspite of rising fuel prices and air fares, the increasing number of short haul passenger trips has contributed immensely to the increase in per capita carbon emission

Pakistan making efforts for Ozone Layer protection
Pakistan is making all-out efforts for the protection of Ozone Layer and has, so far, implemented 32 projects for phasing out Ozone Depleting Substances (ODS). Iftikhar Ahmed, Technical Expert, United Nations Development Program (UNDP), and Ozone Cell, Ministry of Environment, said while talking to TheNation here on Thursday. He informed that Pakistan had agreed along with 191 other countries to phase out chemicals responsible for depleting Ozone layer by the year 2010 under an international treaty called Montreal Protocol, which Pakistan had ratified in 1992.

India-Pakistan nuclear war would cause ozone hole
Nuclear war between India and Pakistan would cause more than slaughter and destruction -- it would knock a big hole in the ozone layer, affecting crops, animals and people worldwide, US researchers said on Monday. Fires from burning cities would send 5 million metric tonnes of soot or more into the lowest part of Earth's atmosphere known as the troposphere, and heat from the sun would carry these blackened particles into the stratosphere, the team at the University of Colorado reported.

End-Permian ozone shield unaffected by oceanic hydrogen sulphide and methane releases
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.

Can amphibians tackle climate change?
Amphibians are known for their resilience. They have bounced out of mass extinctions, survived vegetation changes, and outlived the dinosaur by evolving distinctive behaviours and morphologies and
