  abstract = {{Scattering in the longwave domain has been neglected in the first
generation of radiative codes and is still neglected in most current
GCMs. Scattering in the longwave domain does not play any significant
role for clear-sky conditions but recent works have shown that it is not
negligible for cloudy conditions. This paper highlights the importance
of scattering by mineral aerosols in the longwave domain for a wide
range of conditions commonly encountered during dust events. The authors
show that neglecting scattering may lead to an underestimate of longwave
aerosol forcing. This underestimate may reach 50\% of the longwave
forcing at the top of atmosphere and 15\% at the surface for aerosol
effective radius greater than a few tenths of a micron. For an aerosol
optical thickness of one and for typical atmospheric conditions, the
longwave forcing at the top of the atmosphere increases to 8 W
m$^{2}$ when scattering effects are included. In contrast, the
heating rate inside the atmosphere is only slightly affected by aerosol
scattering: neglecting it leads to an underestimate by no more than 10\%
of the cooling caused by aerosols.

  abstract = {{We use an ocean-atmosphere general circulation model coupled to land and
ocean carbon models to simulate the evolution of climate and atmospheric
CO$_{2}$ from 1860 to 2100. Our model reproduces the observed
global mean temperature changes and the growth rate of atmospheric
CO$_{2}$ for the period 1860-2000. For the future, we simulate
that the climate change due to CO$_{2}$ increase will reduce the
land carbon uptake, leaving a larger fraction of anthropogenic
CO$_{2}$ in the atmosphere. By 2100, we estimate that atmospheric
CO$_{2}$ will be 18\% higher due to the climate change impact on
the carbon cycle. Such a positive feedback has also been found by Cox et
al. [2000]. However, the amplitude of our feedback is three times
smaller than the one they simulated. We show that the partitioning
between carbon stored in the living biomass or in the soil, and their
respective sensitivity to increased CO$_{2}$ and climate change
largely explain this discrepancy.
