%X In this paper, we present a continuous time series of the mean annual and seasonal air temperatures for King George Island (KGI), for the period of 1947-1995, combining data from several meteorological stations in the South Shetland Islands. These series are analyzed for trends. The series are also compared with the mean monthly sea ice extent, recorded at 60ºW. The mean annual temperature during this period was -2.8ºC, with a minimum of -5.2ºC, in 1959, and a maximum of -0.8ºC, in 1989. This record shows a warming trend of 0.022ºC a-1, in the studied time interval, a rise of 1.1ºC in 49 years. Winter shows the most pronounced seasonal warming trend, 0.038ºC a-1, or 1.9ºC in the period. These trends are better definedthan at the Faraday station. Abrupt variations in the mean annual temperature, up to 3.9ºC over three years, have been recorded. Spectral analysis of these time series shows cycles of 5.3 and 9.6 years. A one-month lag is observed between the winter months mean temperatures in KGI and sea ice extent in the 60ºW sector.
