Effects of Ipcc Sres Emissions Scenarios on River Runoff: a Global Perspective Effects of Ipcc Sres* Emissions Scenarios on River Runoff: a Global Perspective

This paper describes an assessment of the implications of future climate change for river runoff across the entire world, using six climate models which have been driven by the SRES emissions scenarios. Streamflow is simulated at a spatial resolution of 0.5 o ×0.5 o using a macro-scale hydrological model, and summed to produce total runoff for almost 1200 catchments. The effects of climate chan...

Future estimates of tropospheric ozone radiative forcing and methane turnover - the impact of climate change

We present a range of estimates for future radiative forcings due to changes in tropospheric ozone (O3T ). Ozone distributions were generated by the UKMO 3-D chemistry-transport model for 1990, 2030, 2060, and 2100, using four sets of boundary conditions. Anthropogenic emissions evolved following either the IPCC SRES “high” (A2) or “central” (B2) case. Each scenario was run with both a fixed (1...

Wedge decomposition analysis: Application to SRES and Post-SRES Scenarios

We introduce a general methodology for displaying the gross assumptions behind any carbon emissions trajectory, relative to a reference trajectory, and we apply this methodology to a limited number of IPCC SRES scenarios [1]. These scenarios have been used widely for climate change analysis. We examine four scenarios (A1B, A2, B1, B2) together with three paired “post-SRES” scenarios [2, 3] that...

Daily relative humidity projections in an Indian river basin for IPCC SRES scenarios

A two-stage methodology is developed to obtain future projections of daily relative humidity in a river basin for climate change scenarios. In the first stage, Support Vector Machine (SVM) models are developed to downscale nine sets of predictor variables (large-scale atmospheric variables) for Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (SRES) (A1B, A2, B1, ...
