Apparently, the historical appearance of these inscribed river stones have “expressed that drought had brought a bad harvest, lack of food, high prices and hunger for poor people,”
One had been originally inscribed with the date of 1417 but the inscription was worn away by ships anchoring. The below article points out "Scientists are particularly concerned about the current European heatwave because its increased intensity has been linked to climate change. But as the hunger stones suggest, the continent has seen its fair share of damaging droughts. A recent study, in fact, found that while 21st century droughts are “the most extreme droughts driven by precipitation deficits during the vegetation period,” they have not been as long or as severe as some of the historic droughts that have struck Europe over the past 250 years."
