Abstract

Climate change is one of the most important issues affecting the world at the beginning of the twenty-first century. This thesis explores changes and trends within the principal climatic parameters temperature for 18 synoptic stations, precipitation for 28 meteorological stations and 16 synoptic stations for evapotranspiration inter alia, during the last 66 years (1945-2010) across Libya. Eighteen meteorological stations were selected along the Mediterranean coast where ten inland stations were selected from the North and South Sahara regions. The study period of temperature is divided into two series of equal length (27 years), 1956 to 1982 and 1983 to 2010 are used to assess and provide comparison in rate of change. Significant increases in temperature are identified, with particularly rapid increases in minimum temperature (0.032 °C a-1; 1945-2010). The rates and periods of change are variable across the study period, with a number of stations documenting declining temperatures during the early phase, with significant increases during the second half of the period, while a mix of increasing and decreasing trends in extreme temperature during the last 50 years (1961-2010) are identified. Precipitation was assessed at 16 stations across Libya (1961-2010), with variable results and no clear pattern emerging for Libya as a whole for the total period, though evidence of a decrease in annual total precipitation (-1.95 mm a-1) is found during the second period. Extreme events as consecutive dry days (
