Interesting article:,

Seems up the permies alley...

New research suggests that the flow of carbon through plants to underground ecosystems may be crucial to how the environment responds to climate change.

"Evidence is also emerging that climate change can cause both local and regional shifts in the composition of vegetation by altering precipitation patterns and temperature regimes and by further elevating atmospheric CO2 concentrations. It’s becoming clear that such long-term shifts in composition of the plant community can affect the transfer of recent photosynthetic carbon belowground and thus affect ecosystem carbon dynamics. For example, Sue Ward and colleagues at the Lancaster Environment Centre, UK, used in situ stable carbon-isotope labeling approaches to show that removing key plant species from a dwarf-shrub heath community strongly affected belowground transfer and metabolism of recently added photosynthetic carbon.9 In particular, the removal of dwarf shrubs greatly increased community-level photosynthesis rates, the transfer of this recently assimilated carbon to soil, and its use by soil microbes, thereby speeding up rates of carbon cycling. There is growing evidence from a variety of ecosystems that plant species and functional groups—different species, such as legumes, grasses, and herbs, with similar physiological characteristics—differentially influence the uptake and transfer of carbon to soil via their exudates, suggesting that global warming-induced changes in plant community structure have the potential to alter patterns of carbon exchange. In general, however, much remains unknown about how changing the composition of plant communities can affect carbon cycling, and an important challenge will be to better understand the role of plant-soil feedbacks in modifying ecosystem carbon dynamics, especially given the extent to which climate-mediated changes in vegetation are already occurring worldwide."

someone should send the researchers videos of Alan Savory and Willie Smits
land use can cause climate change (deserts, rain patterns, the resilience of the environment to adapt to stess)
this has nothing to do with global warming and atmospheric CO2 and shouldn't be in the same article
