The uncertain changes in the climatic conditions of the UAE will bring
Answers
Answer:
recent decades, changes in climate have caused impacts on natural and human systems on all continents and across the oceans [1]. The United Arab Emirates (UAE) and the Arabian Gulf region are no exception. The UAE, covering an area of 83000 Km2, with extended coastlines and small islands, is consequently more prone to the impact of climate change especially that it is also undergoing rapid growth and huge urban developments [2]. The UAE population is in a steady rise and its climate is changing like everywhere else, with the increase of atmospheric CO2 and temperature and the abnorm-alities in rainfall events [3]. In Abu Dhabi, by 2050, the average temperature will increase by around 2.5°C, while rainfall will change by between -21.2% and +10.3% using General Circulation Models (GCM) [3].
GCMs are numerical models predicting atmospheric physical processes, ocean dynamics and land surface processes, while presenting the most advanced predictive tools available to simulate the impact of increased greenhouse gas levels on the global climate system [4]. Relying on such models, the Intergovernmental Panel on Climate Change (IPCC) reported that the last three decades were consistently warmer than any preceding decade since 1850 [1]. Consequently, some low-lying regions and islands are required to confront high impacts that could have a cost as much as several percent points GDP [1]. Unfortunately, this recent impact of climate change may have far reaching negative impacts. The combination of water shortages and high population growth rates accelerate the risks of the Middle East to future climate change [5]. Simulations results reported by [6] reveal large magnitude of possible biospheric influences of climate change. Biodiversity, coral species, coastal sustainability and water resources could be affected by climate change in the UAE [3].
