Is the accelerated expansion evidence of a forthcoming change of signature on the brane?

We show that regular changes of signature on brane worlds in AdS5 bulks may account for some types of the recently fashionable sudden singularities. Therefore, the possibility that the Universe seems to approach a future sudden singularity at an accelerated rate of expansion might simply be an indication that our brane world is about to change from Lorentzian to Euclidean signature. Both the brane and the bulk remain fully regular everywhere. We present a model in which the weak and strong energy conditions hold on the brane, in contrast with the standard cosmologies leading to the analogous kinematical behavior (that is, with a diverging Hubble factor)
