Why Is 1.5°C Important?

  • At 1.5°C, over 70% of coral reefs will die, but at 2°C, all reefs over 99% will be lost.

  • Insects, vital for pollination of crops and plants, are likely to lose half their habitat at 1.5°C but this becomes almost twice as likely at 2°C.

  • The Arctic Ocean being completely bare of sea ice in summer would be a once per century likelihood at 1.5°C but this leaps to a once a decade likelihood at 2°C.

  • Over 6 million people currently live in coastal areas vulnerable to sea-level rise at 1.5°C degrees, and at 2°C, this would affect 10 million more people by the end of this century.

  • Sea-level rise will be 100 cm higher at 2°C than at 1.5°C.

  • The frequency and intensity of droughts, storms and extreme weather events are increasingly likely above 1.5°C.
