Over the past 20 years, climate-change impacts across North America have become more frequent, intense and affect more of the population . Despite scientific certainty of the anthropogenic influence on climate change, misinformation and politicisation of climate-change science has created polarisation in public and policy domains in North America, particularly in the USA, limiting climate action . Vested interests have generated rhetoric and misinformation that undermines climate science and disregards risk and urgency . Resultant public misperception of climate risks and polarised public support for climate actions is delaying urgent adaptation planning and implementation . Drawing upon Indigenous knowledge, enhancing communication and outreach and undertaking collaborations to co- create equitable solutions are critical for successful climate action.
