s evidence of shorelines of a lake more than 450 meters (1,476 feet) deep that formed about 3.4 billion years ago. The study indicates that conditions favorable for flowing water and lake formation may have existed for thousands of years on Mars during the Hesperian epoch, which has been thought to be a period during which surface conditions did not allow significant hydrological activity. The authors suggest that the sedimentary deposits associated with the lake in Shalbatana Vallis should be considered a priority for further study by future landed Mars missions.

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
