Climate change is the greatest global threat to ecosystems on the Earth. Previous studies assessed the impacts of climate change on sensitive tropical coral reefs, extreme environments in European Alps and the Arctic with a focus on snow and permafrost. This article reflects on the past developments and future challenges for scientific research and policy response relating to these topics from a peer's perspective. This leads to the identification of several warning signs for potentially dangerous developments in these sensitive system and extreme environments as well as opportunities for research and policy in the future. While urgent actions are required to limit global warming, science-based policy can provide needed guidance.
气候变化是地球上生态系统面临的最大全球威胁。以往的研究评估了气候变化对敏感的热带珊瑚礁、欧洲阿尔卑斯山的极端环境以及北极地区（重点关注积雪和永久冻土）的影响。本文从同行的角度反思了与这些主题相关的科学研究和政策应对的过去发展及未来挑战。这促成了对这些敏感系统和极端环境中潜在危险发展的若干警示信号以及未来研究和政策机遇的识别。虽然需要采取紧急行动来限制全球变暖，但基于科学的政策能够提供所需的指导。
