Is Global Warming Making Flooding Worse?

Throughout time, society has become more and more industrialized, and global warming has really started to make an impact on our environment. As the effects of global warming are starting to be seen around the world, one aspect of our environment that is going to change are natural disasters, or more specifically flooding.

One thing that long term climate change does is make for more extreme weather patterns.

Recent trends according to NOAA

As global temperatures rise, so will the amount of rainfall because the warmer the atmosphere the more rainfall an area will receive. This might be problematic for flooding since the main cause of floods is excessive rainfall. The NOAA actually went in and examined the record breaking rainfall in Louisiana in 2016 and came to the conclusion that the rains were 10% more intense due to climate change. This trend is only expected to increase in the future as temperatures continue to rise unless we can find a solution to stop or slow down global warming.

A warmer atmosphere holds and subsequently dumps more water. As the country has heated up an average of 1.8 degrees Fahrenheit since 1901, it has also become about 4 percent wetter, with the eastern half of the United States growing soggiest. In the Northeast, the most extreme storms generate approximately 27 percent more moisture than they did a century ago. Basically, because of global warming, when it rains, it pours more.
