Indian projections, under future climate change scenario of increase Green House Gas(GHG) concentrations, indicate marked increase in both rainfall and temperature into the 21st century, particularly becoming conspicuous after 2040’s. Increase in GHG concentrations may lead to overall increase in the rainy day intensity by 1-4 mm/day except for small areas in northwest India where the rainfall intensities decrease by 1 mm/day.
According to India Meteorological Department, the monsoon rainfall at All India level does not show any trend but there are some regional patterns. This in turn would impact yields of crops. The process of climate change is slow and its effects on agriculture are projected to be apparent over several decades. 
                                               The emerging results of analysis of impact of climate change on forest biomes in India seem to be highly vulnerable to the projected change in climate. Majority of the vegetation in India is likely to be less optimally adapted to its existing location and consequently vulnerable to the adverse climatic changes. Biodiversity is also likely to have adverse impact due to this.
