Can effective marine management mitigate climate change impacts so that the Baltic Sea regains a good environmental status? Can record blue-green algae blooms and other extreme events with an impact on future tourism be averted? A team led by Markus Meier from the IOW now presents a study, in which various greenhouse gas and nutrient pollution scenarios are modelled up to the year 2100. Only in the most optimistic scenario – nutrient reduction according to a perfect implementation of the Baltic Sea Action Plan – a good environmental status is achievable and extreme algae blooms can be avoided despite increasingly frequent heat spells.
