A report released this week by Environment Missouri suggests climate change could make extreme weather events, such as droughts and storms, more common and possibly more severe.
The report states that research shows the U.S. has experienced an increase in heavy precipitation events, with the rainiest 1 percent of all storms delivering 20 percent more rain on average at the end of the 20th century than at the beginning.
That is called radar, which didn’t exist at the beginning of the twentieth century. Heavy rainfall events are not increasing, we just have much better spatial coverage now. Radar captures the peak rainfall in a region, whereas the odds of a rain gauge catching the peak are extremely low. The Joplin author has convinced himself that heavy rain events are increasing, but it simply isn’t true.
The report does not cite any information about the possibility of more tornadoes or the probability of more severe ones, such as the EF-5 tornado that struck Joplin on May 22. The research into climate change and tornadoes is inconclusive, said Ted Mathys, state advocate for Environment Missouri.
Actually, the data is quite conclusive. Severe tornadoes are declining.state climate of missouri
