In a world heated by a global warming of 2°C, the annual fishing catch will decrease by 3.3 million tonnes.

In a world heated by a global warming of 1.5°C, the annual fishing catch will decrease by 1.5 million tonnes.

Express the reduction of the annual fishing catch in a world warmed by 2°C as a fraction of the reduction in annual fishing catch in a world warmed by 1.5°C.
