Global change is disproportionately affecting cold environments (polar and high elevation regions), with potentially negative impacts on microbial diversity and functional processes. In most cold environments the combination of low temperatures, and physical stressors, such as katabatic wind episodes and limited water availability result in biotic systems, which are in trophic terms very simple...

Understanding the link between temperature and educational outcomes is important in assessing the efficiency and equity implications of various schooling interventions and the potential welfare impacts of climate change. Using student-level administrative data for the largest public school district in the United States, I estimate the causal impact of hot temperature on high-stakes exam perform...

In this study the impact of climate change on temperature, rainfall and river flows of the Zayandeh Rud basin under two climate change scenarios for two periods (2010-2039 and 2070-2099) are investigated. For the evaluation of future climate change impact on stream flow to Chadegan reservoir, the global circulation model (GCM) outputs of the HadCM3 model (monthly temperature and precipitation) ...

Recent advances in quantifying biochemical and cellular-level responses to thermal stress have facilitated a new exploration of the role of climate and climate change in driving intertidal community and population ecology. To fruitfully connect these disciplines, we first need to understand what the body temperatures of intertidal organisms are under field conditions, and how they change in spa...

In the present study, in order to monitor and project climate change impacts on model of the bioclimatic design, a comparative study was conducted between the Middle East and Eurasia as two different climates. This paper used the basic data from 1990 to 2010, and the CMIP5 climate models have been used to project the climate data (radiation, temperature, wind speed, and relative humidity) from ...

climate change around the world is now a reality that has adverse effects on the environment and human health. there is little information about the effect of climate change on food systems, especially seafood from the farm to the table. the aim of this study was to review the fundamental effects of climate change on seafood safety and human health. climate change is expected to increase chemic...

Thermoregulatory behaviour represents an important component of ectotherm non-genetic adaptive capacity that mitigates the impact of ongoing climate change. The buffering role of behavioural thermoregulation has been attributed solely to the ability to maintain near optimal body temperature for sufficiently extended periods under altered thermal conditions. The widespread occurrence of plastic ...

Using an extensive network of occurrence records for 293 plant species collected over the past 40 years across a climatically diverse geographic section of western North America, we find that plant species distributions were just as likely to shift upwards (i.e., towards higher elevations) as downward (i.e., towards lower elevations)-despite consistent warming across the study area. Although th...

projected global climate change may have a major influence on crop yield. the likely effects of climate change caused by increasing atmospheric carbon dioxide levels on rice yield in iran were evaluated using a mechanistic growth model for rice, gsac-rice, running under a climate change scenario predicted for a doubled-co2 (2xco2) atmosphere by the geophysical fluid dynamics laboratory (gfd...
