    Hoegh-Guldberg, O, Jacob, D, Taylor, M, Bolaños, TG, Bindi, M, Brown, S, Camilloni, IA, Diedhiou, A, Djalante, R, Ebi, K, Engelbrecht, F, Guiot, J, Hijioka, Y, Mehrotra, S, Hope, CW, Payne, AJ, Pörtner, HO, Seneviratne, SI, Thomas, A, Zhou, G & Warren, R, 2019, ‘The human imperative of stabilizing global climate change at 1.5°C’. Science, vol 365.


    Increased concentrations of atmospheric greenhouse gases have led to a global mean surface temperature 1.0°C higher than during the pre-industrial period. We expand on the recent IPCC Special Report on global warming of 1.5°C and review the additional risks associated with higher levels of warming, each having major implications for multiple geographies, climates, and ecosystems. Limiting warming to 1.5°C rather than 2.0°C would be required to maintain substantial proportions of ecosystems and would have clear benefits for human health and economies. These conclusions are relevant for people everywhere, particularly in low- and middle-income countries, where the escalation of climate-related risks may prevent the achievement of the United Nations Sustainable Development Goals.
