Sentences with phrase «about vegetation response»
And I suspect that vegetation models would mostly be tuned to simulate interior forest behaviour and so might not be that informative about vegetation response to changing diffuse / direct light near the tree line with open and sparse forest cover.

«the last glacial period is a good example of a large forcing (~ 7 W / m ^ 2 from ice sheets, greenhouse gases, dust and vegetation) giving a large temperature response (~ 5 ºC) and implying a sensitivity of about 3ºC (with substantial error bars).»
As we have discussed previously, the last glacial period is a good example of a large forcing (~ 7 W / m2 from ice sheets, greenhouse gases, dust and vegetation) giving a large temperature response (~ 5 ºC) and implying a sensitivity of about 3ºC (with substantial error bars).
Model studies for climate change between the Holocene and the Pliocene, when Earth was about 3 °C warmer, find that slow feedbacks due to changes of ice sheets and vegetation cover amplified the fast feedback climate response by 30 — 50 % [216].
«the last glacial period is a good example of a large forcing (~ 7 W / m ^ 2 from ice sheets, greenhouse gases, dust and vegetation) giving a large temperature response (~ 5 ºC) and implying a sensitivity of about 3ºC (with substantial error bars).»
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.
Model studies for climate change between the Holocene and the Pliocene, when Earth was about 3 °C warmer, find that slow feedbacks due to changes of ice sheets and vegetation cover amplified the fast feedback climate response by 30 — 50 % [216].
Rainfall change and variability is very likely to affect vegetation in tropical grassland and savanna systems with, for example, a reduction in cover and productivity simulated along an aridity gradient in southern African savanna in response to the observed drying trend of about 8 mm / yr since 1970 (Woodward and Lomas, 2004a).
This can tell us a lot about responses on the ground to changing climate that occur prior to actual changes in the composition of vegetation species.
