Ragweed may expand its range northward with climate change

A new predictive model developed by ecologists and climate scientists suggests that climate change may allow common ragweed to extend its growing range northward and into major northeast metro areas, worsening conditions for millions of people with hay fever and asthma.Although other factors and modeling approaches should be explored, we offer preliminary insight into where common ragweed might be a new concern in the future. Due to the health impacts of ragweed, local weed control boards may be well advised to monitor areas of expansion and potentially increase eradication efforts.
