New paper predicts CO2 fertilization will greatly improve plant productivity by 40-60% — Paper published in Biogeosciences
Study 'finds the increase in CO2 levels since 1850 has greatly enhanced plant fertilization & a doubling of CO2 levels would be predicted to increase plant productivity by 40 - 60%'
The study derives ‘a probabilistic prediction for globally averaged strength of CO2 fertilization in nature, for period 1850 to 2000 AD, implicitly net of other limiting factors such as nutrient availability” & predicts, ‘the increase in gross primary productivity (GPP) in response to a doubling of CO2 from pre-industrial values is very likely (90% confidence) to exceed 20%, with a most likely value of 40–60%’
