Atmosphere–ocean coupled global climate models (GCMs) are the main source to simulate the climate of the earth climate. The computational grid of the GCMs is coarse and so, they are unable to provide reliable information for hydrological modelling. To eliminate such limitations, the downscaling methods are used. The present study is focused on simulating the impact of climate change on the beha...
بررسی تاثیر تغییرات اقلیمی آینده بر آورد رسوب معلق حوزه های آبخیز ( مطالعه موردی: حوزه آبخیز شهرکرد)
Climate change is one of the most important challenges that influenced different parts of human life on the earth. Evaluation of climate change phenomenon and its possible outcomes on hydrological processes can decrese the challenges of managers and planners of water resources in the next period. The main aim of this study is to evaluate the effect of climate change on sediment output of Share...
[1] Simulations of potential vegetation distribution, natural fire frequency, carbon pools, and fluxes are presented for two DGVMs (Dynamic Global Vegetation Models) from the second phase of the Vegetation/Ecosystem Modeling and Analysis Project. Results link vegetation dynamics to biogeochemical cycling for the conterminous United States. Two climate change scenarios were used: a moderately wa...
Quantitative information on the response of global terrestrial net primary production (NPP) to climate change and increasing atmospheric CO2 is essential for climate change adaptation and mitigation in the 21st century. Using a process-based ecosystem model (the Dynamic Land Ecosystem Model, DLEM), we quantified the magnitude and spatiotemporal variations of contemporary (2000s) global NPP, and...
Identifying the species most vulnerable to extinction as a result of climate change is a necessary first step in mitigating biodiversity decline. Species distribution modeling (SDM) is a commonly used tool to assess potential climate change impacts on distributions of species. We use SDMs to predict geographic ranges for 243 birds of Australian tropical savannas, and to project changes in speci...
b a c k g r o u n d & aim: this study aimed to estimate and project the current and future disability burden of typhoid fever in iran associated with climate and population to provide best policies for climate change adaptation. methods & materials: years lost due to disabilities (ylds) were measured as burden estimation in this study. the temperature was selected as climate variable. futu...
track assessment of the global impacts of climate change, a major input to the much-heralded Stern Review on the Economics of Climate Change, indicates that through the year 2100, the contribution of climate change to human health and environmental threats will generally be overshadowed by factors not related to climate change. Hence, climate change is unlikely to be the world’s most important ...
Economically optimal operational changes and adaptations for California’s water supply system are examined for a dry form of climate warming (GFDL CM2.1 A2) with year 2050 water demands and land use. Economically adaptive water management for this climate scenario is compared to a similar scenario with the historical climate. The effects of population growth and land use alone are developed for...
Climate change adaptation studies on urban flooding are often based on a model chain approach from climate forcing scenarios to analysis of adaptation measures. Previous analyses of climate change impacts in Copenhagen, Denmark, were supplemented by 2 high-end scenario simulations. These include a regional climate model projection forced to a global temperature increase of 6°C in 2100 as well a...
