In this paper, according to the data of 17 weather stations in Khuzestan during 1951–2012, the trend of climate changes and its severity were evaluated. A consistent correlation was highlighted for trends of De Martonne index as indicator of climate and temperature index in some stations. Based on the results of the temperature analysis, 88.31% of the Province became warmer, 6.3% became colder,...

[1] Pronounced changes in land use and surface properties like those that have occurred in the Sahel could lead to reduced land surface emissivity and thus might have an asymmetric impact on daytime and nighttime surface air temperature. This paper analyzes the sensitivity of simulated climate and energy balance to changes in soil emissivity over the Sahel using the recently developed Community...

Global climate change is expected to have broad ecological consequences for species and communities. Attempts to forecast these consequences usually assume that changes in air or water temperature will translate into equivalent changes in a species' organismal body temperature. This simple change is unlikely because an organism's body temperature is determined by a complex series of interaction...

Climate is a complex system which is changing mainly due to the increase of greenhouse gases. Because of the importance of climate change and the effects it can have on water resources, in recent years, this topic has been taken into consideration for different basins on Earth. The objective of this study is to investigate the effects of climate change and forecasting meteorological variables o...

The water crisis is one of the important issues in the Middle East countries. Many lakes are ‎drying up and/or facing critical situations, exerting tremendous impacts on the socio-economics ‎of their region. Lake Urmia, in northwestern Iran, currently is facing critical situations and is on ‎the brink of total ‎shrinkage and environmental disaster. This paper investigates the roots of crises ‎t...
