May was the second-wettest month in the contiguous U.S. on record and had the highest recorded levels of carbon dioxide, the National Oceanic and Atmospheric Administration (NOAA) has announced.

In a month that saw severe flooding devastate parts of the Midwest, a total of 4.41 inches of rain fell, about 1.5 inches above average. That is the second-highest rainfall total in at least 125 years, since recording began in 1895, the NOAA said Thursday,

In the 12 months from June 2018 to May 2019, the amount of rain shattered all previous records — and was 7.73 inches above average, the agency reported.

May was the wettest month ever for Nebraska, Missouri and Kansas — some of the states where recent floods have inundated cities and disrupted day-to-day life.
