Pollen season has begun: the consequences of climate change are affecting allergy sufferers. Alder and hazel are already starting to bloom, “willow, elm and poplar are just getting started,” says Dominik Jung.

“It's almost the rule that hazels bloom at Christmas time.” In the past, the winter months were considered a break for allergysufferers. The fact that climate change is bringing new plants and new allergies could also become a burden to Germany.
