Conference resultsConference resultsIncreasing rates of climate variability and
change are observed during the last decades in SEE:
a) Global warming has been registered since the second half of the 20th century causing an increase in frequency of various extreme weather events and natural hazards (such as droughts, heat waves, intensive precipitation, floods, storms, sea level rise, forest fires, water and wind soil erosion, etc) in the region of SEE
b) This tendency is expected to continue in the future

• regional differences in cloudiness change regarding climate change in the southeastern part of Europe
• total cloudiness shows negative sign of changes, which means less cloudiness parallel with 0.5K increase in northern hemispherical temperature
• Ac, Cb and Cu increase; As, Ci, Sc, Ns and St decrease parallel with global warming
• the three geographical factors, namely the altitude, latitude and longitude explain partially the regional changes in different type of clouds
