more from the ragweed report: The increase in the length of the ragweed season ranged from one extra day in the southern part of the range (Oklahoma). It increased in a linear fashion to the north where it was 16 days longer in Minnesota, and 25 days longer in Manitoba. > Overall, these data indicate a significant increase in the length of the ragweed pollen season by as much as 13–27 days at latitudes above 44°N since 1995. The current study illustrates, on a continental scale, a clear association between recent warming, and an increase in the duration of ragweed pollen season, a major aeroallergen. Furthermore, this finding regarding surface temperatures and allergy season length is consistent with the IPCC projections of disproportionate warming at higher latitudes *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
