The Role of Northern Ecosystems in the Global Methane Budget to the current level of 1.7ppmv (Bolin et al., 1994; Khalil and Rasmussen, 1987). Blake and Rowland (1988) estimated the globally averaged increase of atmospheric CH. between 1978 and 1987 to nearly 16ppbv (parts per billion by volume) yr.; however, this increase declined substantially during the l斗争 发表于 2025-3-27 13:46:07
The Responses of Vegetation to Past and Future Climate Changesse gases” is the amplification of these changes at higher latitudes, especially in the northern hemisphere and in winter (Houghton et al., 1990, 1992). Arctic and Boreal ecosystems thus may experience the greatest impacts of “global warming.” Palaeoenvironmental evidence, however, suggests that past地壳 发表于 2025-3-27 19:14:37

The Arctic has been predicted to warm more rapidly and to a greater extent than the rest of the biosphere (Maxwell, 1992). Also, these once pristine and relatively isolated places are now subject to considerable disturbHarass 发表于 2025-3-28 00:33:33
