The litter that slowed down the carbon cycle
@joseppenuelas
@GlobalChangeBio
Great analysis by Yue He just published. A slower litter carbon turnover is a good news for carbon sinks, at least in the short term. Yet missing an accounting of woody debris.

Greening drylands despite warming consistent with CO2 fertilization
Cool paper

@GlobalChangeBio
showing that the same increase of soil moisture makes more green leaves than 30 yr ago. Rising CO2 -> plants reduce their marginal water loss
