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...

due to the growth of industries and factories, deforestation and other environmental degradation a well as greenhouse gases have been increasing greenhouse gases on the earth's surface in recent decades. this increase disturbs the climate of the earth and is called climate change. an increase in greenhouse gases in the future could exacerbate the climate change phenomenon and have several ...

the goal of this study was to estimate the sensitivity of reference evapotranspiration (et0) to changes in meteorological parameters in the caspian region. long-term meteorological data (1961-2008) were obtained from three synoptic meteorological stations. the region was primarily classified into three climatic zones, based on de martonne climate classification. the penman–monteith equation was...

climate change impacts on precipitation and temperature world-wide are not yet well understood (especially for precipitation), due to their complexity and regional variability. in this study in order to explicit the impact of climate change on precipitation and temperature in iran, 15 aogcm whose greenhouse gases scenarios ran under a2, a1b and b1 were used. monthly precipitation and temperatur...

Abstract Background and purpose:Climate change has an important role on the health and productivity of the occupant of the building. The objective of this study is to estimate the effects of climate change on thermal comfort in hot and wet areas, as in the case of the city of Douala. Materials and Methods:The general circulation model (CSMK3 Model, Scenario B1) was adopted for this purpose.Outd...

climate change which is derived by increase of atmospheric co2 concentration and other greenhouse gases could have considerable effects on productivity of crops in the future. climate change impacts on chickpea yield were investigated and yield maps of dryland areas of zanjan province were provided. investigated scenarios were control scenario, in which simulated current situation, and climate ...

1. introduction as strongly accepted among climatologists, climate change is a result of human activities. there is disagreement about how to define climate change, because of tremendous difference of climate changes in scale, intensity and occurrence time in various regions. recently there have been several observation analyses involving daily and extreme daily temperature trend and variabilit...
