Abstract	Evidence from climate models suggests that the global climate is changing in an unprecedented manner, mainly due to rapid increase in the atmospheric concentration of greenhouse gases. The increase in greenhouse gas emissions in most parts of the world, including India is likely to continue in the near term. The Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change [1] indicates a global warming of about 0.2°C per decade for a range of emission scenarios described in the Special Report on Emissions Scenarios (SRES) over the next two decades. Even if the concentrations of greenhouse gases and aerosols were to stabilize at year 2000 levels, a 0.1°C per decade increase in global temperatures is projected [2]. The Intergovernmental Panel on Climate Change (IPCC) report [1] clearly indicates the likelihood of considerable warming over sub regions of South Asia, with greater warming in winter than in summer. Results of multimodal Global Climate Model (GCM) run under B1 and A1F1 scenarios project an increase in average surface air temperature over South Asia, with the greatest increase being projected for winter months [3]. The projected rise in temperature for winter months exceeds the global mean surface temperature rise (1.8 to 4°C) at 2090-2099 relative to 1980-1999 under B1 and A1F1 scenarios [2]. Results of GCMs suggest that absorbing aerosols have significantly influenced warming of the lower troposphere over Asia [4]. The Himalayan region, which provides a critical source of water for China, India and Pakistan, is among the areas most vulnerable to global warming. Over the last century, global mean temperatures increased at a rate of 0.07°C per decade, but the warming has not been globally uniform, with high northern latitudes particularly affected [5]. A recent study by Ohmura [6] based on observations from the last 50 to 125 years found enhanced warming with elevation in about two-thirds of the mountain regions examined.
