text: As EPA's own data show, despite allegedly "unprecedented" warming, U.S. air quality has improved decade-by-decade since 1970 as emissions declined. The report blames climate change for the Midwest drought of 2012. But the government's own analysis concluded otherwise: "Neither ocean states nor human-induced climate change, factors that can provide long-lead predictability, appeared to play significant roles in causing severe rainfall deficits over the major corn producing regions of central Great Plains." The Assessment ignores substantial data and research finding no long-term increase in the strength and frequency of tropical cyclones and no trend in extreme weather-related damages once losses are "normalized' (adjusted for changes in population, wealth, and consumer price index).
