Abstract

Abstract F01 The third assessment report of intergovernmental panel on climate change (IPCC) represented a consensus among the world’s leading climate scientists that rapid climate changes were occurring on a global scale and define climate change as “any change in climate over time, whether due to natural variability or as a result of human activity”. Climate change indicators should give an overview of the climate and it’s development. Climate change indicators are primarily used to simplify the complex reality and to communicate, more succinctly of critical information regarding climate trends. In establishing indicators, a distinguish can be made between primary indicators based on analysis of directly observed meteorological data, and secondary indicators based on responses of the living world to climate changes which provoke in living organisms. Precipitation data in the region were obtained from the Libyan National Climate Center (LNCC). The runoff collected in dams records were obtained from General Water Authority (GWA). The research has assessed a few of potential indicators for western region of Libya and has established several potentially valuable data sources which satisfy or partially satisfy the requirements that a good indicators should have. The runoff monitoring began 1972 when there is no awareness of climate change, but the importance of this data has now been realized. Both the meteorological data and water resource monitoring data have been shown to provide useful information on climate change in Libya. Clearly the climate in Libya is changing, as it always has, and as it always will. The indicators examined in this study suggest that despite a maritime location buffered by the Mediterranean sea from extremes of climate. Libya is mirroring, albeit at a some what delayed the climate change rate, not as the trends apparent at global scale. This study show importance of climatological data and water resource data records, and importance of depending on charting of climate data for more accuracy in predicting climate change.
