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.
Researchers have been working to swiftly demonstrate how human-driven climate change directly contributes to individual extreme weather events such as the hurricanes, fires, droughts and floods that have battered the world this year.
But linking how global warming affects health — such as driving outbreaks or spreading disease — remains a new field.
Rising temperatures are expanding the range of dengue, a climate-sensitive disease transmitted by mosquitoes. A study estimates that 19 per cent of current dengue cases are linked to climate change.
In the next 25 years, areas in Latin America and Asia could see a 200 per cent rise in cases due to warming, affecting over 257 million people.
