Ron Johnson is a Climate Change Denier

Sen. Ron Johnson

"I absolutely do not believe in the science of man-caused climate change," Johnson said. "It's not proven by any stretch of the imagination. It's far more likely that it's sunspot activity or just something in the geologic eons of time."


What climate change means for Wisconsin

  • Changing temperature and precipitation patterns can affect the life cycle and distribution of insects, many of which transmit diseases that already pose problems to public health in Wisconsin. In 2010, there were 2,505 cases of Lyme disease in the state.
  • In Wisconsin, there were more than 4,800 hospital admissions for asthma in 2011, with an average charge of close to $13,300 for each stay.
  • Ragweed, which can cause hay fever and trigger asthma attacks, may bloom earlier due to warmer spring temperatures. Madison and Lacrosse experienced 13 and 14-day increases in their ragweed pollen season respectively between 1995 and 2011.
  • Midwesterners will experience increased frequency and intensity of extreme weather events due to climate change, including heat waves, floods, and lake-effect snow. In 2011, 11 of the 14 U.S. weather-related disasters with damages of more than $1 billion occurred in the Midwest. While severe flooding is already an issue in the region—in 2008, floods caused 24 deaths and $8 billion in agricultural losses—likely increases in precipitation in winter and spring and more heavy downpours mean it is expected to become more commonplace. Greater evaporation in the summer is also likely to result in water deficits. Longer and more extreme heat waves will impact human health through reduced air quality and increases in insect and waterborne diseases, and require increased use of electricity for cooling, further increasing carbon pollution. While the longer growing season provides the potential for increased crop yields, increases in heat waves, floods, droughts, insects, and weeds will present growing challenges to managing crops, livestock, and forests.
