Sentences with phrase «vegetation feedbacks»

There's a general feeling that dynamic vegetation feedback may be necessary to get this right, but it's a subject that's much in flux.

In addition, they find that accounting for vegetation feedbacks leads to increased warming in summer at higher latitudes and a reduction in summer warming at lower latitudes.

Betts, R. A., Cox, P. M., Lee, S. E. & Woodward, F. I. Contrasting physiological and structural vegetation feedbacks in climate change simulations.

Considering the carbon - cycle feedback, some models (e.g. Cox et al.) estimate large positive vegetation feedback (increased soil respiration, lower photosynthesis due to increased vegetation stress, increased fire frequency...) and some of the most extreme scenarios predict the CO2 concentration to be up to 980 ppm.

However, models have a tendency to overestimate the mid-continental drying in Eurasia, which is further amplified when vegetation feedbacks are included (Wohlfahrt et al., 2004).

We calculate land ice, sea ice and vegetation feedbacks for the 18K climate to be fland ice ∼ 1.2 - 1.3, fsea ice ∼ 1.2, and fvegetation ∼ 1.01 - 1.1 from their effect on the radiation budget at the top of the atmosphere.

Is this in fact the case, or do the climate - vegetation feedbacks overwhelm the land disturbance effects?

Climate change, phenology, and phenological control of vegetation feedbacks to the climate system.

Vegetation feedbacks were invariably reported as an amplifying feedback — which is interesting because that encompasses both «fast» and «slow» feedbacks.

Assessing 20th century climate — vegetation feedbacks of land - use change and natural vegetation dynamics in a fully coupled vegetation — climate model

You can get abrupt change in ocean and atmospheric regimes that change the global energy budget with ice, cloud, dust and vegetation feedbacks.

Climate model tests of the anthropogenic influence on greenhouse - induced climate change: The role of early human agriculture, industrialization, and vegetation feedbacks

Their projections show an increase to growing season length, vegetation productivity (outside of the southeastern US) and biomass, as well as increased plant water - use efficiency.They also find that vegetation feedbacks may increase warming in summer at higher latitudes and reduce summer warming at lower latitudes.
