The line chart WW-I-1 ’Terrestrially stored water’ shows the deviations of the entire terrestrially stored water masses from the long-term mean for the months of the period 2002–2021 in millimetres. The time series is marked by distinct fluctuations. While there is still a tendency towards positive anomalies at the beginning of the 2000s, it is clear that in Germany, the terrestrially stored water masses have been decreasing substantially since the beginning of 2010.

GE-I-3 ’Birch pollen burdens’ contains a biaxial chart. For the years from 1995 to 2021, the lines show the annual mean total of birch pollen in thousand pollen per cubic metre air. A differentiation is made between the central, northern, eastern, southern and western regions. In addition, the mean pollen total across all regions is illustrated. The curves fluctuate between 2 and 20 thousand pollen per cubic metre air.

The bar chart GE-I-2 ’Heat-related mortalities’ shows the estimated number of heat-related mortalities for the period from 1992 to 2021. A particularly high number of heat-related mortalities occurred in 1994 with the highest maximum value so far amounting to some 10,000 mortalities. In the years of 2003, 2006 and latterly 2018 the heat also led to an extraordinarily high number of mortalities. There is no significant trend discernible.

The illustration GE-I-1 ’Heat stress’ contains two lines indicating the number of hot days and the number of tropical nights respectively, in terms of the German area mean for the years from 1951 to 2021. Besides, the bar chart shows, for the years from 2005 to 2021, the mean number of days on which warnings were issued regarding major as well as extreme heat stress in the GWS warning districts. There is no significant trend discernible for the development of the number of days with heat warnings.

A graph shows the agricultural nitrogen surpluses for individual years and as rolling 5-year means between 1990 and 2022. The 5-year-mean nitrogen surpluses in kilogrammes per hectare dropped from 117 to 77. The target for 2028-32 is 70 kilogrammes per hectare and year.

A graph shows the proportion of vulnerable ecosystems in Germany where the critical loads for eutrophication were exceeded between 2000 and 2019 and the target for 2030. In 2000, the share was 84 % and in 2019, it was 69 %.

The chart consists of two rows of six nationwide maps each of Germany. The top row of maps shows the annual mean number of days with a soil humidity of less than 30 per cent usable field capacity for winter wheat on sandy clay, while the number of days in the bottom row refers to clay-rich sand. The six maps each cover the following periods: 1963–1972, 1973–1982, 1983–1992, 1993–2002, 2003–2012 and 2013–2022.

The chart consists of two illustrations – one showing the number of days with soil humidity of less than 30 per cent usable field capacity (nFK) for winter wheat on sandy clay while the other shows – for the same number of days – the comparable value for winter wheat on clay-rich sand, each for the period of 1961 to 2022. The multi-annual mean for the period of 1991 to 2020 for sandy clay amounts to 5.3 days. The linear trend for Germany regarding the period examined amounts to an increase by 8.6 days.
