Climate change means more mosquito days, increasing Zika risk.

More than 130,000 people living in Wisconsin are especially vulnerable to extreme heat.

By 2050, the typical number of heat wave days in Wisconsin is projected to increase from around 10 to nearly 60 days a year.

As the planet continues to warm from the increase in greenhouse gases in the atmosphere, the temperatures that we consider to be normal are also rising.

Summers are getting muggier as the dewpoint temperature rises

Dangerous heat days that are currently rare in Wisconsin are projected to occur much more regularly by 2050. 

Milwaukee is the 15th fastest-warming city in the U.S.

Wisconsin is projected to see an increase in severity of widespread summer drought of approximately 145 percent by 2050.

Milwaukee had one of the largest sewage overflows in the country in April 2015, spilling over 680 million gallons.

In Wisconsin, there are nearly 200,000 people living in areas at an elevated risk of inland flooding.

It’s not just April showers: more water can evaporate into a warmer atmosphere at all times of the year, and what goes up must eventually come down. 

According to the National Climate Assessment, the most extreme precipitation events (those in the 99th percentile of intensity) have increased in every region of the contiguous states since the 1950s.
