6. Land cover changes influence regional climate
Human-induced land cover changes (LCCs), such as the clearing of forests for farming, can affect climate. To study the regional and global effects of LCC, Pitman et al. analyze seven different climate models. Each model simulation is run several times, with prescribed land cover reflecting conditions in 1870 and in 1992. The authors find that in all models, LCC has a statistically significant regional effect on latent heat flux and near-surface temperature. Furthermore, they find that LCC affect temperature only in the region where the land cover change took place, not in remote regions. While all models show significant regional effects, these vary across models for several reasons arising from diffe
