assessing the potential impacts of 21st-century climate change on species distributions and ecological processes requires climate scenarios with sufficient spatial resolution. in this study we projected future changes in maximum temperature and minimum temperature under cmip3 sres and cmip5 rcps scenarios with two station-based datasets (arazkoseh and nodeh) of the eastern golestan province. ch...

In this study the impact of climate change on temperature, rainfall and river flows of the Zayandeh Rud basin under two climate change scenarios for two periods (2010-2039 and 2070-2099) are investigated. For the evaluation of future climate change impact on stream flow to Chadegan reservoir, the global circulation model (GCM) outputs of the HadCM3 model (monthly temperature and precipitation) ...

The climate changes have an important role in distribution of plant species. Statistical species distribution models (SDMs) are widely used to predict the changes in species distribution under climate change scenarios. In the peresent study, the distribution of Alopecurus textilis in the current and future climate condition (2050) under the influence of climate change and two scenarios of RCP 4...

Results of assessment of the future climate change impacts is associated with some uncertainties. Considering the range of uncertainties increases reliability of the results. In this study, climate change impacts on daily precipitation, maximum and minimum temperature of Sira basin are assessed using LARS-WG model, for 2036-65 period. Accordingly, uncertainty of new emissions scenarios (RCP2.6،...

increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...

Introduction and Background: The agricultural sector is one of the most important economic sectors due to extensive interaction with the environment, the greatest impact of climate change takes effect.  The agricultural sector affects climate change and affects climate change. Climate change, on the one hand, affects agricultural performance and, on the other hand, affects the price of produ...
