KKLT without AdS
  According to the KKLT scenario, metastable dS vacua are formed as a result of
uplifting of supersymmetric AdS vacua by $\overline {D3}$ branes. I describe an
extended version of this scenario where metastable dS vacua appear after an
uplift from a state where the potential of the volume modulus in the absence of
$\overline {D3}$ branes would be unbounded below. This mechanism may
considerably strengthen vacuum stabilization in the early universe.
