Growing Season Length and Climatic Variation in Alaska
The growing season has lengthened in the contiguous United States since 1900, coinciding with increasing northern hemispheric air temperatures. Information on growing season trends is needed in arctic regions where projected increases in air temperature are to be more pronounced. The lengths of the...

The growing season has lengthened in the contiguous United States since 1900, coinciding with increasing northern hemispheric air temperatures.
