The quick rate of retreat of the Triglav Glacier, which began in the second half of the 20thcentury, further accelerated till the beginning of the 21st century. Due to increasing intensity of ice thinning, outcropping rocks began to emerge in the middle of the glacier, which disintegrated into two parts in 1992. In the last part of the first decade of the 21st century, the glacier has been retreating at a slower rate. The last major recession of the glacier was registered after the above average hot summer of 2003.

The length of the annual growing season is increasing almost everywhere in Europe, mostly in Eastern and Northern part, and less in Western Europe, the Mediterranean and in southern Europe. In Slovenia, the length of the annual growing season is increasing, especially since the mid-1990s. According to projections, the duration of the annual growing season throughout Europe will increase in the future.

Bad

Temperature observations show increasing trend of maximum and minimum absolute temperature in between 1961 and 2018, reflecting a global warming. Number of hot days is increasing, including the frequency of extreme hot days with daily maximum temperature above 35 °C. Number of days with temperature below zero show a decline.

Bad

Total greenhouse gas emissions will increase in Slovenia up to 2020 (in relation to 2015 data). After 2020, levels will decrease. GHG emissions not included in the ETS are according to current projections up 2020 significantly lower than the target values.

Bad

Trends in annual precipitation are not as obvious as temperature trends, changes between years and regions are significant. According to the climate change projections, annual precipitation will slightly increase while changes in seasonal precipitation will be noticeable. We shall be worried about summer conditions, because less precipitation and higher temperature might result in higher frequency of droughts. In winter, more precipitation may lead to an increase in flooding events.

Bad

Precipitation is highly variable in space and time, even more than temperature (storms and hail). In the last two decades, Slovenia is observing catastrophic droughts and abundant precipitation resulting in floods, sometimes drought and floods occur even within the same year. The maximum snow cover depth and the depth of fresh snow decreased in the period 1961-2011.

Neutral

Water consumption in Slovenia represents a relatively small proportion of the annual gross water outflow from the country. In 2018, the annual WEI+ index was around 3%, or, compared to the periodic average of water availability. The Long-term Annual Average Water Exploitation Index shows a slight decrease, but the trend is not statistically significant.

Bad

In the period 2002-2017, the highest exposure to ozone concentrations were detected in the Primorska region in summer where air quality measuring stations in Koper and Nova Gorica detected highest ozone concentrations in ambient air. There are some differences from year to year in a level of ozone exposure due to meteorological conditions in the warm half of the year and other regional characteristics.
