Economic sectors highly reliant on climate, such as agriculture, tourism, fisheries and forestry, have higher levels of exposure and sensitivity  and greater overall risk to climate change compared with other economic sectors such as mining, construction and manufacturing . However, the cascading nature of climate impacts related to trade , labour productivity  and infrastructure  means that there is no economic sector in North America that will be unaffected by climate change  . For Canada, this assessment is further supported by the Canadian Climate Assessment . The combined economies of Canada, Mexico and the USA represented ~28% of the global GDP in 2019, with the USA accounting for almost 90% of the total activity for North America . The risks posed at different global warming levels  for any given economic activity or sector are presented in Figure 14.10. By combining expert judgement with a systematic review of the literature for each sector, the information in Figure 14.10
