Discussion

It is now known that high carbon dioxide emissions caused by global warming can significantly accelerate the occurrence of severe droughts by reducing the amount of arid land required for seed dispersal.천안출장안마 The resulting climate effects are, however, extremely small, mainly because dry soils are able to absorb most of the CO 2 and thus can be grown much more slowly than dry soils. By contrast, the presence of dry soils means that high carbon dioxide emissions can lead to an increased frequency of flooding events, which in turn are often more severe. However, the high frequency of flooding events can be partly compensated by an increased yield, at least in places where rainfall is sparse. The yield in regions that are not flooded is less than in densely flooded regions because increased water availability decreases the water demand f제주출장만남or plant cover and reduces erosion, leading to fewer and smaller cracks and erosion. Thus, the increase in carbon dioxide and decreased frequency of floods are compensatory, and both are required for the continued survival of cultivated fruit trees.

The occurrence of severe droughts could increase the amount of arid land necessary to grow crops, which could ultimately lead to the loss of agricultur바카라 검증 사이트e, with or without global warming (Dijkstra et al., 2010; Jääskeläinen, 2000; Tätzänen and Pääläinen, 2004). This suggests that, with future warming, it could be even more important that arid lands are reforested before CO 2 emissions increase. As climate sensitivity increases (i.e., increasing its warming-induced impact over time), so does the need for reforestation, and thus the relative abundance of arid lands in agricultural fields. For example, during the Holocene extinctions, a large proportion of arid land on Earth was lost. As this number increased, the proportion of arid land increased and so did the need for reforestation (Mann et al., 2001). Therefore, arid land could be the dominant factor in sustaining agriculture in the future, or it could be reduced to a small proportion.

The ability of some species to recover in response to greenhouse warming is now clear, in some cases by a relatively large degree (Stott et al., 2004). The most recently studied taxon, the African grasshopper, is a relatively large species, and so has been able to recover remarkably rapidly in response to global warming. The African gras
