Abstract: We argue that de Sitter vacua in the LARGE-volume scenario of type IIB string theory are vulnerable to various unsuppressed curvature, warping and g_s corrections. We discuss how these corrections affect the moduli vevs, the vacuum energy and the moduli masses. Our analysis reveals that the corrections are parametrically larger in the relevant expressions than one might have guessed from their suppression in the off-shell potential. Some corrections appear without any parametric suppression at all, which makes them particularly dangerous for candidate de Sitter vacua. Other types of corrections can in principle be made small for appropriate parameter choices. However, we show in an explicit model that this is never possible for all corrections at the same time when the vacuum energy is positive.
