Climate Change Could Bring Misery for Hay Fever Sufferers

Experts have warned, climate change could help a notorious invasive weed known to trigger severe allergy attacks gain a foothold in the UK.
Ragweed, or Ambrosia artemisiifolia, is native to North America but has been spreading rapidly across warmer parts of Europe since the 1960s. It is still rare in the UK, but by 2050 could be scattering pollen throughout much of England, inflicting new levels of hay fever misery, research suggests.
The plant’s pollen not only induces severe allergic reactions but also extends the hay fever season from summer to autumn. Last year, researchers from the University of Leicester recorded airborne ragweed pollen levels in the East Midlands high enough to cause significant hay fever attacks.
