The importance of water and air in our daily life is clear to everyone, though they represent fragile Earth resources that can change abruptly at times. Understanding the mechanics of climate change provides us with an essential need to prepare for the future. Saudi Arabia has huge ancient groundwater reserves that are continuously under increasing demand. The total number of wells in Saudi Arabia increased by more than 100% from 1982 to 1990, and the total irrigation demand in 1997 was 22,933.4 million cubic meters (Rasheeduddin et al., 2001). This type of research has been applied over Saudi Arabia for the first time and will open many opportunities to investigate the effects of climate change on various sectors and resources in Saudi Arabia. In this study we will shed light on what is expected to face us with regard to precipitation, wind speeds, runoff, temperature, and evaporation. This information can point the sensitive areas that might be affected by climate change and help in designing a proper plan to manage our water resources. This research will provide future climate variables for scenario A2 which calls for high emission of carbon dioxide and explosion of the world population (Treut et al., 2007). Those climate variables can be used by hydrologists to predict the effects of climate change on the recharge of aquifers and consequently the future status of aquifers in terms of storage and yields by implementing available hydro-logic models.
