(No) Ice on Erken

The Erken Laboratory has monitored the duration of ice cover of lake Erken since the 1940s. The data shows a strong decrease in the average duration of ice cover over time. This year, in particular, the situation is special as the lake has so far only been frozen for 5 days this winter. If the situation remains like this, it would be by far the shortest duration of ice cover since the start of measurements.
