How climate change is contributing to flash flood events across the country
"A warmer atmosphere can hold more water vapor, which is a fundamental component for showers and storms. More water vapor in a storm leads to heavier rainfall."
"A one-degree rise in air temperature correlates to a 4% increase in water vapor content in a cloud, impacting rainfall levels significantly."
"San Antonio has observed a 6% increase in rainfall intensity from showers and storms. In flood-prone regions, this increment can escalate a heavy rain event into a dangerous flash flood."
"Climate change influences flash floods, evident in the recent deadly floods across central Texas, New Mexico, and the Carolinas."
Recent deadly flash floods across central Texas, New Mexico, and the Carolinas were exacerbated by slow-moving thunderstorms and heavy rain. While climate change is not the sole cause, it significantly affects rainfall patterns. A warmer atmosphere increases water vapor capacity, which contributes to heavier rain. Research indicates that a one-degree temperature rise corresponds with a 4% increase in water vapor in clouds, leading to increased rainfall intensity in flood-prone regions such as San Antonio. A seemingly small increase in rainfall intensity can transform heavy rains into life-threatening flash floods.
