The basic POD: the Norse are able to hold onto their American possessions due to a slightly improved climate in the 1000s-1100s. This has plenty of ripple effects, the most obvious being that the playing field in America is radically equalized, with more Western nations getting into the act (such as the Moorish and African Caliphates) and with Native nations having a better chance to recover from the initial waves of plague, adopt Western technology, and resist encroachment (at least for now!).
