The occurrence of wind erosion and the spread of dust particles can be regarded as one of the most important and threatening environmental factors. Climate change and the frequency of droughts have played an important role in exacerbating or weakening these events. The primary objective of the present study was to investigate the trend of changes in four important climatic elements (precipitati...
the scientific community agrees that climate change is one of the greatest challenges that oursociety will have to face this century. indeed, the fourth report from the intergovernmental panel on climatechange (ippc) confirms the certitude of this phenomenon and its impacts, which can range from droughts tofloods, health problems and food shortages. the principal objective of this paper is to a...
Extreme climatic events have a major role in the structuring of biological communities, and their occurrence is expected to increase due to climate change. Here I use a manipulative approach to test the effects of extreme storm events on rocky mid-shore assemblages. This study shows that an extreme storm can cause more negative effects than several mild storms, primarily by bringing the biologi...
Extreme Value Theory is the branch of statistics that is used to model extreme events. The topic is of interest to meteorologists because much of the recent literature on climate change has focussed on the possibility that extreme events (very high or low temperatures, high precipitation events, droughts, hurricanes etc.) may be changing in parallel with global warming. As a specific example, t...
Climate-related agricultural vulnerabilities, as well their implications for food security and farm livelihoods, have been extensively documented. Extreme weather events such floods, droughts, heat cold waves, hailstorms, strong winds, cyclones, other increased the exposures of agriculture to climate risk. These processes are hampered by a lack appropriate climatic elements, resulting in an unf...
Bioclimatic models aimed assessing a species’ sensitivity to climate change incorporate mean shifts in climate variables; however the more acute threat to the persistence of species may result from increased frequency of extreme climatic events, including increased duration and severity of droughts. Here we assess climate-change sensitivity using niche modeling that unlike bioclimatic modeling ...
Extreme climate events have significant influences on ecological systems and social economic systems. The global climate is becoming warmer and warmer, so extreme climate events will probably increase in both frequency and intensity, and the Northwest arid region of China is situated in the middle latitudes, all of which combine to make this area become the most sensitive region to global clima...
