We prove new cases of the Fontaine-Mazur conjecture, that a $2$-dimensional $p$-adic representation $\rho$ of $G_{\mathbb {Q}, S}$ which is potentially semi-stable at $p$ with distinct Hodge-Tate weights arises from a twist of a modular eigenform of weight $k\geq 2$. Our approach is via the Breuil-Mézard conjecture, which we prove (many cases of) by combining a global argument with recent results of Colmez and Berger-Breuil on the $p$-adic local Langlands correspondence.
