Why will climate change aggravate floods?

It is reported that on August 29th, 2007+2065438 local time, Hurricane Harvey brought about 1250 mm of rainfall to a place in southern Texas, setting a record for the largest rainfall caused by a single tropical cyclone in 48 states except Hawaii and Alaska. Climate change has aggravated the flood.

According to the report, Claire Nalis, a spokeswoman for the World Meteorological Organization, said that climate warming means that when we encounter a meteorological event like Harvey, the rainfall may be higher than the original level, and warmer air can hold more water vapor, which will also produce more rainfall. As the sea level rises, coastal storm surge floods will become more serious.

Meteorologists also said that climate warming is still a polarized issue in the United States, and there are already differences in the United States. Every time a major climate event like Harvey occurs, the meteorological community begins to debate whether it is necessary to start discussing the potential relationship between extreme weather and climate change.

It is reported that as of August 29th, at least 18 people have died in the disaster or accident caused by Harvey, and about17,000 victims in Houston have entered the shelter. At present, the disaster has not been effectively controlled.
