3.     In this review, we explore these findings to ask two interconnected questions: (a) how does sociality impact vulnerability to climate change, and (b) how might climate change impact social organization in bees? In doing so, we generate predictions about the impacts of climate change on the expression and distribution of social phenotypes in bees. Furthermore, we emphasize that social and solitary bee populations could be differentially impacted by climate change due to important behavioral, physiological, and life history differences.
