Allergies: Europe’s ragweed pollen counts to quadruple by 2050?

28 mayo 2015

Airborne concentrations of common ragweed pollen, a potent allergen, could increase fourfold in Europe by 2050. Researchers believe climate change will be responsible for two thirds of this increase, while the remainder will be due to the plant’s spread, as a result of human activity. These estimates show that it is now necessary to implement coordinated management of this invasive plant on the European level, through long-term pollen monitoring and mapping of the weed’s distribution.
