Analysis of Average Temperature in Libya According to CCKP Data During the Period 1901-2022

This research analyzes the average temperature in Libya during the period from 1901 to 2022, based on data from the World Bank's Climate Change Knowledge Portal. The aim is to determine the trend of this long-term series. The data was processed using statistical software EViews 13. The findings indicate that the series is non-stationary and exhibits a statistically significant positive trend, as confirmed by the Augmented Dickey-Fuller test and the KPSS test. This trend is attributed to the global climate change currently affecting the world. The extreme weather phenomena witnessed in Libya are features of this change. The dry desert climate has expanded at the expense of semi-arid and Mediterranean climates. Furthermore, the last three decades have been the hottest in 120 years, with the average increase potentially reaching one degree Celsius compared to what was prevalent before the 1990s.
