Effects of Climate Change on West Nile Virus

A study projects how climate change may affect virus-carrying mosquitoes across the southern U.S. Changes are expected to vary with region, and the southern states should see a trend toward longer seasons of mosquito activity and smaller midsummer mosquito populations

The varied influence of climate change on temperature and precipitation may have an equally wide-ranging effect on the spread of West Nile virus, suggesting that public health efforts to control the virus will need to take a local rather than global perspective, according to a study published this week in the scientific journal Proceedings of the National Academy of Sciences.

Got Milk? Climate Change Means Stressed Cows in Southern U.S. May Have Less

“Cows are happy in parts of Northern California and not in Florida” is a good way to sum up the findings of new research from the University of Washington, said Yoram Bauman, best known as the “stand-up economist.”

Bauman and colleagues found that the decline in milk production due to climate change will vary across the U.S., since there are significant differences in humidity and how much the temperature swings between night and day across the country. For instance, the humidity and hot nights make the Southeast the most unfriendly place in the country for dairy cows.

Their study combined high-resolution climate data and county-level dairy industry data with a method for figuring out how weather affects milk production. The result is a more detailed report than previous studies and includes a county-by-county assessment — that will be available to farmers — of the impact climate change will have on Holstein milk production in the U.S. through 2080.
