Satellite Observed: Longer growing season trend in the north(1980s)From Myneni et al. (Nature, 386:698-701, 1997)Analyses of two independent data sets for the period1981 to 1994 suggest that -- Vegetation greenness averaged over the peak boreal growingseason months of July and august increased by 10%- The timing of spring green-up advanced by about 6 days- The satellite data are concordant with an increase in the ampli-tude of the seasonal cycle of atmospheric CO 2exceeding 20%since the early 1970s, and an advance in the timing of thedraw-down of CO 2in spring and early summer of up to 7 days(Keeling NDVI et al., averaged Nature, over 382:146-149, boreal growing 1996) season months ofMay Greenness to September during the increased boreal by forest about growing 10%, seasonthe months timing of May of spring to September green-up increased advanced by about 10%, 6 days.the timing of spring green-up advanced by about 6 days.- greening in the north/the northern latitude greening trend during the 1980s & 1990s
