The main aspects of the climate changes and variability, climate change scenarios, vulnerability to climate change and adapting options in Slovakia are presented. Significant rise of atmospheric temperature and decrease of precipitation were observed in Slovakia in the 20th century. The most of climate change scenarios elaborated for Slovakia are predicting an increase in annual mean temperature by 2 - 4 OC and uncertain changes in precipitation. The climate change issues were the topics of research in the Slovak National Climate Program and the U.S. Country Studies Program. The two documents - First and the Second National Communication on Climate Change - were prepared by the Slovak government in 1995 and 1997.
