In computer models, European scholars estimate substantially different climate change impacts for global warming of 1.5°C and 2°C by 2100, the two temperature limits policy makers agreed on in the Paris climate agreement.
The simulation concluded that an additional 0.5°C would mean a 10-cm-higher global sea-level rise by 2100, longer heat waves, and would result in virtually all tropical coral reefs being at risk.
