Increasing global temperatures wrought by greenhouse gas emissions have boosted the number of dengue cases, new research shows.

Climate change is responsible for nearly a fifth of the record number of dengue cases worldwide this year, US researchers said on Saturday, seeking to shine a light on how rising temperatures help spread disease.

Amid record year for dengue infections globally, a new study has found that climate change is responsible for 19 per cent of rising dengue burden.

New research suggests that climate change is currently driving a surge in global dengue infections and that case rates could increase by 60% by 2050.
