Models
These types of models, which include plant physiological responses, reduce estimates of future drought severity compared to atmosphere-centric models.
What are Earth System Models (ESMs)?
This index, which does not account for changes in plant water needs under higher CO2, was criticized for overestimating future drought.
What is Potential Evapotranspiration (PET)?
In the Plant responses to increasing CO2 study, what does the “CO2rad” in the graphs mean?
what is CO2 radiative forcing
This common drought severity index often overestimates future drought stress by not accounting for plant physiological responses.
What is the Palmer Drought Severity Index (PDSI)?
This part of the plant is responsible for regulating gas exchange and water loss and was found to decrease in density as CO2 levels rise.
What are stomata?
The percentage by which stomatal density decreased in Woodward’s herbarium species over the last 200 years due to rising CO2 levels.
What is 40%?
This term refers to the difference between precipitation and evapotranspiration, a plant-centric metric that reduces estimates of drought stress
What is P-E?
According to Dr. Zipf (PHD,DOD,POTUS) this is often known as the rate of gas exchange and water loss through the leaf
Stomatal conductance
In the Woodward study, experimental increases in CO2 of 60ppm led to this percentage decrease in stomatal density in controlled environments.
What is 67%?
The significant global-scale bias in predicting future drought stress arises when this physiological process in plants is ignored.
What is stomatal conductance?
The impact of increased vapor pressure deficit (VPD) on stomatal conductance
Decreased stomatal conductance
The plant physiological impact of increased atmospheric CO2 in Woodward’s study
Decreased stomatal density
This coupled model type was used in the Swann et al experiment
What is the CMIP5
Stomatal conductance plays a role in these two plant processes
