北极的陆地冰正在融化，海冰正在减少，永久冻土正在融化。这些北极要素的变化是相互关联的，大多数相互作用加速了变化的速度。这些变化通过海平面上升、风暴和飓风影响恶化以及变暖加剧，影响到北极内外（包括温带和热带地区）人民的基础设施、经济和文化。世界各地的沿海社区已经经历了更经常的洪水，饮用水污染和海岸侵蚀。我们描述和总结了北极永久冻土，陆地冰和海冰的变化的性质，及其对低纬度地区，特别是美国的影响。我们强调，除非个人、企业、社区和政策制定者积极参与减缓和适应活动，以减少北极变化的影响，保护人民和社会，否则未来的影响将进一步恶化。
Arctic land ice is melting, sea ice is decreasing, and permafrost is thawing. Changes in these Arctic elements are interconnected, and most interactions accelerate the rate of change. The changes affect infrastructure, economics, and cultures of people inside and outside of the Arctic, including in temperate and tropical regions, through sea level rise, worsening storm and hurricane impacts, and enhanced warming. Coastal communities worldwide are already experiencing more regular flooding, drinking water contamination, and coastal erosion. We describe and summarize the nature of change for Arctic permafrost, land ice, and sea ice, and its influences on lower latitudes, particularly the United States. We emphasize that impacts will worsen in the future unless individuals, businesses, communities, and policy makers proactively engage in mitigation and adaptation activities to reduce the effects of Arctic changes and safeguard people and society.
