Terrestrial and Inland Water Systems

摘要: The topics assessed in this chapter were last by the IPCC 2007, principally WGII AR4 Chapters 3 (Kundzewicz et al., 2007) and 4 (Fischlin 2007), but also Sections 1.3.4 1.3.5 (Rosenzweig 2007). SPM stated “Observational evidence from all continents most oceans shows that many natural systems are being affected regional climate changes, particularly temperature increases,” though they noted documentation of observed changes tropical regions Southern Hemisphere was sparse Fischlin al. (2007) found 20 to 30% plant animal species had been time considered be at increased risk extinction if global average increase exceeds 2°C 3°C above preindustrial level with medium confidence, substantial structure functioning terrestrial, marine, other aquatic ecosystems very likely under degree warming associated atmospheric CO2 concentration.
