Climate change influences events such as droughts, floods, extreme temperatures and sea level changes and hence affects the global food production, energy generation, and water resources adversely. Rising greenhouse gas (GHG) concentrations in the atmosphere are considered the dominant cause of climate change. General Circulation Models (GCMs) are used for the projection of climate into future, accounting for the GHG concentrations. However, the coarse spatial resolution of GCM outputs does not permit their direct use in catchment scale studies. Therefore either dynamic or statistical downscaling techniques are used for linking GCM outputs to catchment scale hydroclimatic variables.
