The EPA’s revocation of the 2009 endangerment finding shifts the burden of proof from federal agencies to state capitals. Governors who declared climate emergencies must now demonstrate with regional data that rising carbon dioxide (CO2) endangers their residents. Wisconsin cannot meet that burden.

In 2019, Wisconsin declared climate change a crisis requiring the state’s electricity to be carbon-free by 2050, citing worsening extreme weather as justification. Since then, the state has spent $6 billion on renewable infrastructure while residents pay 15% more for electricity than the Midwest average.

A new report by the Weiss Energy Policy Institute analyzed 130 years of Wisconsin climate data and found that as atmospheric CO2 rose 45%, Wisconsin experienced 63% fewer days over 90°F, heatwaves 71% shorter in duration, powerful tornadoes down 70%, and significant drought decline since 1894. This isn’t just absence of evidence, it’s negative correlation. As CO2increased, climate extremes decreased.

In addition to the improving climate, the report also notably found that rural Wisconsin’s average temperature has not changed since 1894. Urban areas, on the other hand, have warmed about 2.2°F since the late nineteenth century. The report finds that this urban warming is nearly entirely due to the Urban Heat Island effect from concrete and development, not CO2. In many measurable ways, Wisconsin’s climate has become more conducive to human flourishing over the past century.
