Oh, the Places Mosquitoes Will Go!

Because of climate change, Aedes aegypti and Asian tiger mosquitoes will move north in large numbers, a new study finds.

Historically, mosquitoes have gone where humans go, with tropical species relying on global migration, international trade, and urbanization to spread from their native habitats in Africa and Asia to the rest of the world. Over the next 60 years, climate change will allow them to move even farther north in larger numbers, to places that have in the past been unfavorable to them.

That’s according to a new study in Nature Microbiology, in which an international team of researchers mapped how global warming could become the primary driver of mosquito expansion.
