“Now it’s more CO2 that will threaten crops“. But plants love CO2! Anthony Watts is confused by this UC Davis press release. Apparently “Rising CO2 levels threaten crops and food quality”. What’s confusing about this, Anthony:
…findings from previous research by Bloom and colleagues suggested that elevated levels of carbon dioxide decreased photorespiration and inhibited nitrate assimilation in plant shoots.
Oh, maybe that ‘whole CO2 is good thing’ isn’t going to stick, even though the partisans at CO2Science.org have an “amazing video”.
