The consumption of HCFCs has grown at an average annual rate of over 11.3 per cent in the past 15 years ndia will phase out hydrochlorofluorocarbons (HCFCs) by the year 2030. These chemicals are widely used in refrigeration and airconditioning systems and are major cause of global warming. While unveiling country's roadmap to phase out the ozone depleting chemicals.
Mumbai Mumbai's weather has been erratic since December, an indication of the worldwide phenomenon of climate change, says Dr R V Sharma, deputy director general, India Meteorological Department (IMD).
Despite its long-recognized importance, nitrous oxide (N<sub>2</sub>O, also commonly referred to as laughing gas) sometimes seems like the forgotten atmospheric gas. Concerns about the stratospheric ozone layer have largely focused on reactions of ozone with chlorine and bromine atoms released from the atmospheric dissociation of chlorofluorocarbons and other anthropogenic halocarbons.
By comparing the ozone depletion potential
This article is an attempt to assess possible changes in the climate of Port Blair, the capital of the Union territory of Andaman & Nicobar Islands.
The most commonly-known f-gases are the early, so-called first generation F-gases: the CFCs that destroyed the ozone layer and were banned by the Montreal Protocol. However, in the race to save the ozone layer, the use of their second generation cousins was accelerated: HCFCs, now also banned under the Montreal Protocol.
The comprehensive road map for phasing out hydrochlorofluorocarbons (HCFCs) in various sectors as per the reduction targets of Montreal Protocol released by the Ministry of Environment and Forests. India plans to cut the use of the HCFCs by 10 per cent by 2015 and then to zero by 2030.

WHILE we are yet to ascertain whether aerosols are warming or cooling our planet, a scientific team has traced a new source: deciduous trees. These are plants that shed their leaves seasonally. So far aerosols were described as particles of pollutants like sulphur dioxide, black carbon (soot) and sea salt that remain suspended in the air. Deciduous plants release around 500 teragrammes
