Earth's climate is currently changing in significant ways as a result of human activities, and future projections indicate continued and possibly accelerating change without reductions in greenhouse gas  emissions . Climate change affects human and natural systems; this chapter provides an assessment of present and future climate-change impacts, risks and adaptation for North America, including Mexico, Canada, the USA and coastal waters within the 370-km exclusive economic zone. We do not consider Hawaii and other island territories of the USA in depth as they are assessed in Chapter 15. Chapter 14 assesses evidence from Arctic Canada and Alaska, which is synthesised in Cross-Chapter Paper 6 Polar Regions .
