BBC News - Carbon emissions linked to Europe's hay fever rise
Carbon dioxide emissions may be raising pollen counts in European cities, according to a continent-wide study.
Researchers from 13 EU nations analysed pollen levels for more than 20 species of tree and plant.
They found that many, including several that cause allergies such as hay fever, correlated with rising CO2 levels.
Are they sure it's not caused by pirates?
