Climate change is one of the most serious environmental and socio-economic problems of our time especially in arid areas. Sudan with the new boarders, most of its land classified as arid and semiarid regions, therefore it is very important to investigate the climate change in these areas. This research aimed to investigate the climate change reality in the arid zone in Sudan using rainfall and temperature data only. Five focal points (Kassala, Wadmedni, Eldouim, Elobied, Elfasher) were selected to represent the whole zone. The climate data of monthly and annual rainfall, minimum and maximum air temperature were obtained from Sudan Meteorological Authority (SMA) during the period from 1980 to 2010. Other climatic factors were calculated and estimated from temperature and rainfall data, such as: Potential Evapotranspiration, Cumulative Rainfall Departure, Effective Rainfall, rainfall coefficient of variance, Aridity Index and Standardized Precipitation Index. The relationship between rainfall and temperature were obtained. The period of this study (1981 – 2010), was divided into three decades and analyzed the different between each sub-period on rainfall and temperature using Duncan Multiple Range (DMR) at P ≥ 0.05. The trend of annual mean air temperature had been increased with statistically significant evidences in Kassala, Wadmedni, Eldouim and Elfasher stations; where annual rainfall trend had been increased with statistically significant evidences in Elobied station. Regarding other climatic factors: Potential Evapotranspiration trend showed significant increase in Kassala, Wadmedni and Elfasher stations; Cumulative Rainfall Departure trend showed significant increase in Wadmedni, Elobied and Elfasher stations; where Effective Rainfall, rainfall coefficient of variance, Aridity Index and Standardized Precipitation Index trends showed significant increase in Elobied station only. There were negative significant correlation between rainfall and temperature in Kassala and Elobied stations. There were no significant different between the three sub-period in annual rainfall in all stations except in Elobied station, where in mean air temperature showed significant different between the three sub-period in Kassala, Eldouim and Elfasher.

Biosphere Reserves all over the world are areas that are deliberately and purposely kept to promote green economy and most importantly mitigate the effect of Global warming and climate change. The problems of climate change arise from the higher concentration of greenhouse gases in the atmosphere which exert a warming effect on the earth. Control of anthropogenic sources and greenhouse gases are constantly discussed and extensively researched in this matter, while the significance of microorganisms remained neglected. Although microorganisms has a contributory effect in global warming as in the case of methanogenes in the rumen of ruminants which has been implicated to increase the environmental methane gases during digestion, the role they play in converting greenhouse gas to useable form in the soil and water hence, reducing global warming cannot be over emphasized. The current review aimed to stress the neglected global importance of microorganisms in climate change. Overall, this review further support the key role biosphere reserves play in protecting soil and plant microorganisms in response to climate change control.

Butterflies are very sensitive insects for climate change, environmental pollution. Butterflies are model for most of the studies which focus on the effect of climate change on the species richness, change in abundance, species distribution, population size; it is also because of butterflies are umbrella species,. The conservation programme of butterflies will surely help to conserve other species from plants to microscopic organisms. In this study an attempt was made to evaluate the change in butterfly population dynamics through different seasons of the year. According to the observation made during research period it is clear that species richness was the highest from August to November (Monsoon and Early Monsoon) followed by Winter. The lowest were in Hot Summer and Summer that is from February to May. This study is an example for the impact of climate change on the diversity of butterflies from semi-arid geographical region of India; revealed the impact of climate on the species composition, species richness and abundance of butterflies. Such studies are very much important to show that the effects of climate change whether it is natural or human induced change the species composition of species directly and indirectly effecting the ecosystem balance.
