  We consider the conundrum of generating de Sitter space from
higher-dimensional geometry, with particular attention to KKLT-type
constructions arXiv:hep-th/0301240 and their 5d implications. We show that even
in the probe approximation with small $g_s$, a consistent higher-dimensional
solution requires a deformation of a modulus field playing the role of a
Goldberger-Wise stabilizing field in Randall-Sundrum type geometries that
occurs through a shift in a the throat length. We identify the light radion
field that sets the length of the throat, whose origin is the dynamical
conifold deformation parameter. By analyzing the theory as a 5d model of
mismatched branes in AdS5 space with a GW stabilization mechanism, we show how
energy (and supersymmetry breaking) is transferred to both the IR and UV
regions of the throat to generate a consistent 4d de Sitter sliced geometry.
This should help resolve some of the recent apparent paradoxes in explicit
higher-dimensional constructions. Moreover, the radion gives insight into the
potential for the previously identified ``conifold instability". We argue that
this instability would be a destabilization of the potential for the radion in
KKLT, which can occur when the perturbation is too large. If indeed
$\sqrt{g_s}M$ is too small, the radion would enter on its runaway direction and
the conifold deformation would shrink to zero size. It is difficult to satisfy
the required bound and a) maintain a hierarchy in the simpler CY manifolds and
b) complete the cosmological phase transition into the stabilized throat, We
also discuss the implications of this type of setup for supersymmetry breaking,
and how multiple throats can introduce hierarchies of supersymmetry breaking
masses, even in an anomaly-mediated scenario. In an appendix we consider
general compactification constraints.
