Guy Barter described the findings as interesting and said it could have an important effect on lightly scented flowers. “We think about climate change in terms of rising temperatures and sea level, but there are more delicate potential effects which we have not thought about,” he said.

Last year, experts warned the average global temperature had risen by 0.5 in 50 years. They predicted temperatures will increase by 3 over the next century, causing a rise in sea level, flooding, disease outbreaks and mass migration of refugees(难民).

The researchers looked at a variety of plants. In the paper the researchers said, “The species with the highest increases in emissions(排放物) were those with the lowest fragrance rates. The increases calculated for floral terpene emissions show that very important increases in the amount of floral scents will likely occur in a warmer world. The rates of floral terpene emissions by the end of the century could increase 0.34 -9.1 times because of a 5 increase in the average maximum temperature during the flowering peak of the season.”
