The fossil plant assemblages,
including spores and pollen grains, provide useful information on past
vegetation and the
response of the
vegetation to climate changes.
Gentine's team is the first to isolate the
response of
vegetation from the global warming total complex
response, which
includes such variables for the water cycle as evapotranspiration (the water evaporated from the surface, both from plants and bare soil) soil moisture, and runoff.
[
Response: There is a Hadley Centre / HadCM3 study on this, using a version of the GCM with
vegetation model
included — William]
For instance, the sensitivity only
including the fast feedbacks (e.g. ignoring land ice and
vegetation), or the sensitivity of a particular class of climate model (e.g. the «Charney sensitivity»), or the sensitivity of the whole system except the carbon cycle (the Earth System Sensitivity), or the transient sensitivity tied to a specific date or period of time (i.e. the Transient Climate
Response (TCR) to 1 % increasing CO2 after 70 years).
Current research focusing on terrestrial animals
includes several studies on the island fox, one on the role of deer mice in affecting
vegetation community recovery, and one on the
response of lizards to the removal of rats on Anacapa.
[
Response: The models that
include a carbon cycle and dynamic
vegetation should have such effects — but this is still a rather experimental class of models.

Instead, to constrain the Charney sensitivity from the ice age cycle you need to specifically extract out those long term changes (in ice sheets,
vegetation, sea level etc.) and then estimate the total radiative forcing
including these changes as forcing, not
responses.
The fast
response from oceans and
vegetation (opposite to each other) leads to a change of about 3 ppmv / °C, while the long term
response (
including ice sheet /
vegetation surface area and - deep - ocean current changes) is about 8 ppmv / °C.
The
response of atmospheric CO2 and climate to the reconstructed variability in solar irradiance and radiative forcing by volcanoes over the last millennium is examined by applying a coupled physical — biogeochemical climate model that
includes the Lund - Potsdam - Jena dynamic global
vegetation model (LPJ - DGVM) and a simplified analogue of a coupled atmosphere — ocean general circulation model.
A research team
including Riikka Rinnan and Magnus Kramshøj from the Center for Permafrost at the University of Copehagen, Denmark recently conducted studies to assess the Volatile organic compounds (VOC) emission
response of
vegetation to warming temperatures in the Arctic.
