climate change is one of the most important factors that will affect different parts of human life on earth and will be adverse effects on environmental resources, economic, social and especially water resources, with changes in rainfall and timing of runoff amount.one of the strategies to mitigate the effects of climate change is to assess its effects on precipitation, temperature and runoff i...

بررسی تغییر اقلیم و نقش انسان در گرمایش جهانی به سبب آزادسازی گازهای گلخانه ای در جو، زمینه غالب مطالعات اقلیمی در دهه های اخیر در کشورهای توسعه یافته بوده است. برای مطالعه تغییرات اقلیمی بررسی پارامترهای حساس و موثر در محاسبه تبخیر و تعرق می تواند گزینه مناسبی برای این امر باشد. در این تحقیق با استفاده از آمار هواشناسی 54 ساله ایستگاه های سینوپتیک از سال 1951 تا 2005 در پنج ایستگاه تهران، اصفه...

Climate change could alter the population growth of dominant species, leading to profound effects on community structure and ecosystem dynamics. Understanding the links between historical variation in climate and population vital rates (survival, growth, recruitment) is one way to predict the impact of future climate change. Using a unique, long-term data set from eastern Idaho, USA, we paramet...

The Solanaceae family with 49 species of 10 genera is one of the important nutritional, economical, medicinal and ornamental families in which six genera of them are classified in the group of wild relatives. Predicting the effect of climate change on the distribution of plant species is important for their management and conservation. In this study, the effects of climate change on this family...

Global climate change is felt disproportionately in the world's most economically disadvantaged countries. As adaption to an evolving climate becomes increasingly salient on national and global scales, it is important to assess how people at the local-level are already coping with changes. Understanding local responses to climate change is essential for helping countries to construct strategies...

The present study analyzes the deployment of technologies to reduce CO2 emission in the global energy sector and the implied costs using the energy-economy-climate model ReMIND. The results depend on the policy chosen for inducing changes of investments. Climate policies price emissions and therefore induce changes of investments. The mitigation costs of less than 1% of GDP are relatively small...

BACKGROUND Global climate change will have multiple effects on human health. Vulnerable populations-children, the elderly, and the poor-will be disproportionately affected. OBJECTIVE We reviewed projected impacts of climate change on children's health, the pathways involved in these effects, and prevention strategies. DATA SOURCES We assessed primary studies, review articles, and organizati...

Climate change is a reality. A warming climate will have large effects on lakes of the Boreal Shield. Our ability to forecast these effects, however, is hampered by a very incomplete understanding of the actual interactions between weather and many aspects of lake ecosystems. Climate change will affect lakes in very complex ways. Changing weather conditions will have direct effects on thermal h...

BACKGROUND Climate influences dengue ecology by affecting vector dynamics, agent development, and mosquito/human interactions. Although these relationships are known, the impact climate change will have on transmission is unclear. Climate-driven statistical and process-based models are being used to refine our knowledge of these relationships and predict the effects of projected climate change ...
