Speaking of what many have called the progressive nitrogen limitation hypothesis, Iversen says that “a disconnect between observed root dynamics and modeled nutrient availability has confounded projections of forest responses to elevated CO2,” stating that “while models predict that soil nitrogen availability will limit forest responses to elevated CO2 (Thornton et al., 2007), many of the forested FACE experiments found a sustained increase in nitrogen uptake from the soil in response to CO2 enrichment (Finzi et al., 2007),”...

The Medieval Warming also brought higher levels of water in lakes and rivers.
