Grassland Root Biomass Response to Atmospheric CO2 Enrichment

CO2Science.org

What it means
The six scientists say "these data suggest that root biomass in grasslands may have changed markedly as atmospheric CO2 increased since the last glacial period, but that more substantial changes are ahead if the air's CO2 content doubles by the end of this century as predicted." And, of course, these anticipated "changes" should all be positive, implying ever greater grassland root biomass -- and all that that phenomenon implies -- as the air's CO2 content continues to climb ever higher.
