『Abstract
　Global warming, greenhouse effect, and the climate change problems are long-term anthropogenic consequences that are expected to threaten water related demand and supply patterns in the near future. These problems may be identified linguistically on a logical basis to take the necessary precautions, and implement mitigation strategies after vulnerability possibilities are assessed using fuzzy logic. Climate change effects are the focus of many scientific, engineering, economic, social, cultural, and global nuisances, and these effects awaits cost-effective remedial solutions. Extreme events such as floods and droughts and modified groundwater recharge may be influenced by climate change.
