Assessing the impacts of both climate and land use changes on hydrologic variables is crucial for sustainable development water resources natural ecosystems. We conducted a case study catchment in southwestern Australia to assess future changes, separately combination, resource availability. For this evaluation, Soil Water Assessment Tool (SWAT) model was first calibrated then forced by 34 glob...

[1] Detection and attribution studies of observed surface temperature changes have served to consolidate our understanding of the climate system and its past and future behaviour. Most recent studies analysing up-to-date observations have relied on general circulation models (GCMs) to provide estimates of the responses to various external forcings. Here we revisit a methodology which instead es...

BACKGROUND This study aims to assess the hepatoprotective potential of Commelina nudiflora against CCl4-induced hepatic injury in rats. METHOD Antioxidant activities were determined. Phytochemical analysis was performed by gas chromatography mass spectrometry (GCMS). In the in vivo study, Sprague Dawley rats were pretreated with C. nudiflora (150, 300, and 450 mg kg body weight (b.wt.)) once ...

Internal climate variability at the centennial time scale is investigated using long control integrations from three state-of-the-art global coupled general circulation models. In the absence of external forcing, all three models produce centennial variability in the mean zonal sea surface temperature (SST) and sea level pressure (SLP) gradients in the equatorial Pacific with counterparts in th...

captures the maximum possible range of changes in surface temperature and precipitation for three continental-scale regions. We find that, of the CMIP5 GCMs with 6-hourly fields available, three simulate the key regional aspects of climate sufficiently poorly that we consider the projections from those models ‘implausible’ (MIROC-ESM, MIROCESM-CHEM, and IPSL-CM5B-LR). From the remaining models,...

The relative performance of global climate models (GCMs) phases 5 and 6 the coupled model intercomparison project (CMIP5 CMIP6, respectively) was assessed in this study based on their ability to simulate annual seasonal mean rainfall temperature over Bangladesh for period 1977–2005. Multiple statistical metrics were used measure GCMs at 30 meteorological observation stations. Two robust multi-c...

The impacts of climate change on groundwater are poorly constrained, particularly in regions such as sub-Saharan Africa where global circulation models (GCMs) project different directions precipitation change. Moreover, the timing when can be differentiated from natural variability has not been quantified. Here, for first time, we estimate time emergence (ToE) levels, using series eight sites a...

In this study, a pattern detection method is applied on the RCP4.5 and RCP8.5 simulation outputs of seven GCMs—disseminated by Coupled Model Intercomparison Project Phase 5 (CMIP5)—to determine whether atmospheric teleconnection patterns detected in ERA-20C reanalysis from European Centre for Medium-Range Weather Forecasts (ECMWF) will be observable future projections CMIP5 GCMs. The technique—...

The process of estimating the effect a changing climate on severity future ocean storms is plagued by large uncertainties; for safe design and operation offshore structures, it nevertheless important that best possible estimates effects made given available data. We explore variability in 100-year return value significant wave height (HS), changes over period time, output WAVEWATCH-III models f...
