State of Canadian Pacific Salmon in 2019 and 2020: Responses to Changing Climate and Habitat

Abstract Excerpt:
Global climate change is the overarching driver of Canadian Pacific salmon trends (Grant et al. 2019). Average land-ocean temperature has risen by 1°C over the last century (IPCC 2018), and the last six years were the warmest on record (Fig. 1; NOAA 2020). This trend is accelerating, emphasizing the need to dramatically reduce greenhouse gas emissions globally (IPCC 2014; White et al. 2016; Holsman et al. 2018; Bush and Lemmen 2019).
