Mosquito-borne diseases get a boost from climate change

MASSIVE SCIENCE

Bugs like it hot, and evolve faster when there’s lots of carbon dioxide

We often think of climate change in terms of extreme weather, but the impacts of global warming will extend far beyond natural disasters. Scientists suggest climate change will also make more of the world hospitable to mosquitoes—and the diseases they carry. To make matters worse, new research shows that climate change may also be supercharging mosquito evolution.

Zika, West Nile, and dengue are just a few of the deadly viruses that depend on mosquitoes to spread. Human diseases like these are also carried by animals like birds and rodents, who don’t always show symptoms. But if a mosquito bites an infected animal, it can later transmit the disease to other animals, including humans. That’s why many disease prevention efforts focus on controlling mosquito populations—a task that’s about to become a lot harder.
