Analyzing the effects of unforced natural variability and anthropogenic forcing on ENSO variability using CESM
… the representative concentration pathway 8.5 (RCP8.5). With this ensemble, and a ~5000 year control run with constant pre-industrial conditions, we examine ENSO variability under different forcing regimes. We compare the effects of anthropogenic climate change with the effects of natural …

The development of Intensity Duration Frequency curves under climate change considerations using Remote Sensed rainfall data in Uganda
… but decreases at higher return periods. Under RCP8.5, most stations recorded increased intensities, whereas Jinja and Gulu showed decreases, reflecting localized climate variability. To support application in ungauged catchments, multilinear regression analysis (MLR) models were then developed …

Future changes in extreme rainfall events and circulation patterns over southern Africa
… concentration pathway 4.5 (RCP4.5) and 8.5 (RCP8.5). Two approaches are followed to identify and analyze extreme precipitation events. First, indices for extreme events, which capture moderate extreme events, are calculated on the basis of model data and are compared with indices from two …

Quantifying biophysical and biogeochemical influence on northern high latitudes greenhouse gases dynamics
… extent driven by two scenarios, RCP4.5 and RCP8.5. Estimated net CH4 emissions for the 2000s are 13.8 TgCH4 yr-1, mostly from wetland soils. Estimated net emissions under RCP4.5 and RCP8.5 are 30% and 64% higher, respectively, in the 2090s than in the 2000s due to 1) higher temperature and …

Modelling broiler chicken health and welfare in a changing climate
… alternative climate change scenarios (RCP2.6 and RCP8.5). Risk of abnormal colour/fever was found to increase as mean temperature dropped below 0℃ on the day of slaughter. Risk of ascites increased as mean temperature rose above 15℃, on the day of slaughter and day 9 before slaughter. Hot (≥16℃) …
