The loss of Arctic sea-ice is one of the most compelling manifestations of man-made climate change. Profound environmental change is already affecting Arctic inhabitants and ecosystems. Increasing scientific evidence, including many key papers by the PI, suggests the impacts of sea-ice loss will be felt way beyond the poles. Linkages between Arctic sea-ice loss and extreme mid-latitude weather have become an area of increasing scholarly enquiry and societal interest. Yet, significant knowledge gaps remain that demand urgent attention; in particular, the robustness of response to sea-ice loss - and its underpinning physical causes - across different climate models.The Polar Amplification Model Intercomparison Project (PA-MIP) will significantly advance the state-of-the-art in understanding and modelling the climate response to Arctic and Antarctic sea-ice loss. It will enable deeper understanding of the causes and global effects of past and future polar change, and the physical mechanisms involved. PA-MIP is a novel and unique collaboration of UK and international scientists. To promote fruitful collaboration and drive research excellence, this proposal supports two key activities: a secondment scheme and a synthesis workshop, both with direct benefit to NERC-funded science.

北极海冰的丧失是人造气候变化的最引人注目的表现之一。深刻的环境变化已经在影响北极居民和生态系统。越来越多的科学证据（包括PI的许多关键论文）表明，海冰损失的影响将超出两极。北极海冰损失与极端纬度天气之间的联系已成为增加学术询问和社会兴趣的领域。然而，仍然需要紧急关注的大量知识差距。特别是，在不同的气候模型中，对海冰损失的反应及其基础的身体原因的鲁棒性。极性放大模型比较项目（PA-MIP）将在理解和建模对北极和南极海冰损失的气候反应方面显着提高最新技术。这将使对过去和未来的极地变化以及所涉及的物理机制的原因和全球影响更深入地理解。 PA-MIP是英国和国际科学家的新颖而独特的合作。为了促进富有成果的合作和推动卓越的研究，该提案支持两个关键活动：借调计划和合成研讨会，均为NERC资助的科学直接利益。
