4 Acceleration Of Global 	 Warming Due To Carbon-Cycle Feedbacks In A Coupled
Climate 	 Model, Nature
 









A NAME="11.4">

Excerpt: General circulation models have generally
excluded the feedback between climate and the biosphere, using
static vegetation distributions and CO2 concentrations from
simple carbon-cycle models that do not include climate change.
Here we present results from a fully coupled, three-dimensional
carbon-climate model, indicating that carbon-cycle feedbacks
could significantly accelerate climate change over the
twenty-first century. We find that under a 'business as usual'
scenario, the terrestrial biosphere acts as an overall carbon
sink until about 2050, but turns into a source thereafter.
