Climate change could lead to surge in hay fever sufferers

Millions of more people could suffer from hay fever as a result of climate change, a study has suggested.

Researchers from Europe, led by the University of East Anglia (UEA), estimated that across the continent the number of people who suffer an allergy to pollen will rise from 33 million to 77 million by 2060.

Climate change will be responsible for two-thirds of this increase, they said.
