In “Clean Air Act” (Feb. 10), Miranda Carter of Environment Illinois claimed global warming is causing more extreme weather. She then said this alleged increase in extreme weather justifies Environmental Protection Agency restrictions on carbon dioxide emissions. Yet scientists working with the National Oceanic and Atmospheric Administration’s Twentieth Century Reanalysis Project have just released a climate and weather study going back to 1871 finding no increase in extreme weather events. I guess we can scrap the EPA regulations after all.
