Abstract This study examines the effects of climate change on runoff in the Yellow River basin in Khuzestan province. In this study, the combination of 14 general circulation models under two emission scenarios A2 and B1 were used for simulating the climatic variables in the next period (2025-2054) compared to the baseline period (1971-2000). The weighting method of mean observed temperature...
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...
Evaluating the relative importance of ecological drivers responsible for natural population fluctuations in size is challenging. Longitudinal studies where most individuals are monitored from birth to death and where environmental conditions are known provide a valuable resource to characterize complex ecological interactions. We used a recently developed approach to decompose the observed fluc...
Climate change and species invasions represent key threats to global biodiversity. Subarctic freshwaters are sentinels for understanding both stressors because the effects of climate change are disproportionately strong at high latitudes and invasion of temperate species is prevalent. Here, we summarize the environmental effects of climate change and illustrate the ecological responses of fresh...
The article advances the hypothesis that the seasonal and inter-annual variability of rainfall is a significant and measurable factor in the economic development of nations. An analysis of global datasets reveals a statistically significant relationship between greater rainfall variability and lower per capita GDP. Having established this correlation, we construct a water resources development ...
Alcamo, J., et al. (2007). "Future long-term changes in global water resources driven by socio-economic and climatic changes." Hydrological Sciences Journal-Journal Des Sciences Hydrologiques 52(2): 247-275. A global water model is used to analyse the impacts of climate change and socio-economic driving forces (derived from the A2 and B2 scenarios of lPCC) on future global water stress. This wo...
W aking up to the sound of crashing waves, ocean views and sandy beaches remains, for many, the dream. However, according to a series of recent reports and studies on rising sea levels, sleepless nights could be in store for beachfront real-estate owners and residents of coastal cities the world over. Earlier this year, the United States’ National Oceanic and Atmospheric Administration (NOAA) r...
Using NDVI satellite data, vegetation growth is shown to be closely correlated with precipitation that fell two months earlier. Aerosols are shown to significantly alter the direct and diffuse sunlight that reaches vegetation, which subsequently has an effect on carbon assimilation and transpiration. Population increases are presented as a primary driver of these regional climate changes in India.
