In the Trulock Bay area of Pine Bluff, Arkansas, June 6,2019. Areas along the Arkansas River saw record-setting flooding caused by heavy rain. As global temperatures continue to rise Arkansas is expected to experience more frequent and intense flooding.

The increase in global greenhouse gas emissions, which traps heat in the atmosphere, is causing temperature to rise. With higher temperatures, more water evaporates from sea and land and the atmosphere holds more water vapor. This in turn increases the chance of more intense rainstorms and the chance of flooding.

How does climate change lead to flooding? Below is the references.

1.Heavier Precipitation

A warmer atmosphere holds and subsequently dumps more water. Due to climate change, the probability of rainfall is at least 40% higher and the intensity is at least 10% higher. Of course, heavier rainfall does not automatically lead to floods, but it increases the potential for them. And even moderate amounts of rainfall can cause serious damage, particularly in places where urban flooding is on the rise.

2.More-Frequent Hurricanes
Climate change is increasing the frequency of our strongest storms. In the Atlantic basin, an 80 percent increase in the frequency of category 4 and 5 hurricanes (the most destructive) is expected over the next 80 years. And stronger storms bring greater rains.
