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...
Emissions of more than three-quarters of greenhouse gases by the energy sector have affected climate change in various economic, political and social sectors. Climate change is affecting energy consumption, including natural gas. This article deals with the future of natural gas consumption in the country with regard to climate change until 2030 using a combined approach of econometrics and sce...

Introduction: Climate changes are one of the factors associated with human activities for the destruction of the ecosystem. This factor leads to global warming, changing rainfall patterns, increasing the amount and severity of climate factors such as storms, and rising sea levels. Parasites are also an integral part of this ecosystem; therefore, the present study considered the effect of climat...

abstract this chapter describes how the climate change is potentially the mostsevere threat to pollinator biodiversity. mounting evidence demonstrates that therehave already been biotic responses to the relatively small climate changes that haveoccurred this century. pollinators such as birds, bees, butterflies, moths, flies, wasps,beetles bats and even mosquitoes are essential for food product...
agricultural land conversion (alc) has been introduced as one of the most important factorsaffecting ecosystem. this type of conversion has led to several challenges in agricultural development andhuman life. monitoring alc plays a crucial role when dealing with such challenges. the main objective of thisstudywas to monitor the trend ofalc in theqazvin province located in northwest iran from 19...
prediction of climatic variables on a local scale by general circulation models of the atmosphere is impossible because the models have large-scale network of resolution. therefore, downscaling methods are used to solve this problem. since the climate change phenomenon can affect different systems such as, water resources, agriculture, environment, industry and economy as well, selection of the...
