Spatio-temporal pattern of cross-continental invasion: Evidence of climatic niche shift and predicted range expansion provide management insights for smooth cordgrass

•Aimed to identify global susceptible regions to smooth cordgrass invasion.•Characterized climatic niche dynamics at spatial and temporal scales.•Observed significant climatic niche expansion with a short lag period.•Future range expansion predicted with marginal climate change.•Mangroves and protected areas are at risk to ongoing and future invasions.
