  • Whether rivers are speeding up or slowing down in a warming Arctic is unclear, but has implications for carbon cycling and infrastructure. This study finds divergent behaviour in migration rates for rivers in discontinuous versus continuous permafrost, driven by changes in permafrost thaw and river ice.

  • Analysis of the sub-seasonal patterns of river migration reveals that permafrost reduces erosion rates and suggests that full permafrost thaw may lead to a 30–100% increase in the migration rates of Arctic rivers.
