Increases in Extreme Precipitation Cost the U.S. $73 Billion
Torrential. Rainstorms can flood homes. Wash out roads and bridges and destroy crops over the past. Three decades flooding from heavy precipitation has caused about two hundred billion dollars of damage in the. Us francis davenport is a phd student. In earth system science at stanford university. She wanted to know how much of that enormous price tag can be blamed on global warming. We've seen that extreme precipitation events are increasing in frequency or intensity and so we wanted to quantify what are the financial costs of those changes in precipitation. Her team analyzed historic rainfall trends and financial data about flood damages over decades. They estimated that between nine thousand nine hundred eighty eight and twenty seventeen about seventy three billion dollars. A flood damage can be attributed to increases in extreme precipitation. That's more than a third of the cost of flooding over those thirty years. So devonport says that people are already paying the financial cost of warming world. I think having those hard dollar amounts is really important for some of these policy conversations about what to do.
