Global warming will affect the world’s coral reefs.
In a world heated by a global warming of 2°C, we will lose 99% of coral reefs.
In a world heated by a global warming of 1.5°C, we will lose 81% of coral reefs.
Express the percentage of coral reefs lost in a world warmed by 2°C as a fraction of the amount of coral reefs lost in a world warmed by 1.5°C. Give your answer in its simplest form.
