![]() ![]() It has resulted in an increase in the number of people and value of property at risk to flooding. In part this expansion is driven by population growth. This needs to be seen in the context of rapid urban expansion in the area and is characterized by a loss in impervious cover. Coupled with sea level rise, climate change has resulted in more frequent and intense flooding, especially in coastal areas. This study highlights that climate change has clearly led to increased precipitation during extreme events in southeast Texas.Taking high-resolution climate models into account, we conclude that two-day extreme precipitation events along the Gulf Coast as intense as observed on 19–20 September 2019 or higher have become 1.6 to 2.6 times more likely due to anthropogenic climate change, or 9% to 17% more intense. ![]()
