For thousands of years, humans have taken every precaution to avoid mosquitoes and the diseases they carry, from Malaria to Zika. But while techniques for fighting the insects have improved dramatically over time, scientists say long-term climate change could soon make protecting humans from mosquitoes much more difficult.

The link between climate change and mosquito-borne illness centers around how rising temperatures may expand the area in which mosquitoes can thrive. Most such illnesses can only be transmitted at temperatures between approximately 16°C (61°F) and 38°C (100°F), according to a World Health Organization report. Perhaps more significantly, the time it takes for mosquitoes to develop decreases significantly the closer temperatures are to around 30°C (86°F). The average global temperature is expected to rise by at least 2°C (3.6°F) by 2100 even if countries take dramatic action to limit their greenhouse gas emissions. In some areas, that shift will be much more dramatic.
