Challenged Start: Condensation, clouds and precipitation → Moist air rises and cools
Line says uplift initiates cooling but cites Oki and Kanae 2006 (doi:10.1126/science.1128845), a paper on global hydrological cycles and water resources that says nothing about uplift or cooling. The uplift-weathering-CO2-cooling…

Challenged Land water partitioning and plant water fluxOki and Kanae 2006 give land precipitation about 113,000 km3/yr with evapotranspiration about 73,000 (about 65 percent) and runoff about 40,000 (about 35 percent), not 60/40; the claim misstates the paper split.

Drainage, groundwater recharge and runoff (about 65 percent of rain returns to air, 35 percent runs off)
Where land precipitation that is not evapotranspired goes: surface runoff, interflow, and deep drainage that recharges aquifers and later returns as baseflow.…

Evapotranspiration partitioning (about 61 percent transpiration, range 35-90)How the water that returns to the air from land splits into plant transpiration, soil evaporation, canopy interception evaporation and open-water or snow loss.…

Infiltration and surface partitioning of rain (rain intensity vs 1-1000 mm/h soil capacity)How rain that reaches the ground is split between entering the soil matrix, bypassing it through macropores, and leaving as overland flow. Rain intensity relat…

Biological weathering by roots, mycorrhizal fungi and microbes (plants speed weathering about 2-10 fold)Plants, fungi and bacteria speed up rock breakdown by exuding organic acids, raising soil CO2, tunneling minerals with hyphae and shifting rhizosphere pH. They…
