Nailing down the unknown neutrino mixing angle \theta _ { 13 } is one of the most important goals in current lepton physics .
In this context , we perform a global analysis of neutrino oscillation data , focusing on \theta _ { 13 } , and including recent results [ Neutrino 2008 , Proceedings of the XXIII International Conference on Neutrino Physics and Astrophysics , Christchurch , New Zealand , 2008 ( unpublished ) ] .
We discuss two converging hints of \theta _ { 13 } > 0 , each at the level of \sim 1 \sigma : an older one coming from atmospheric neutrino data , and a newer one coming from the combination of solar and long-baseline reactor neutrino data .
Their combination provides the global estimate

\sin ^ { 2 } \theta _ { 13 } = 0.016 \pm 0.010 ( 1 \sigma ) , implying a preference for \theta _ { 13 } > 0 with non-negligible statistical significance ( \sim 90 \% C.L . ) .
We discuss possible refinements of the experimental data analyses , which might sharpen such intriguing indication .
