The severity and frequency of extreme rainfall are both increasing due to the reality of warmer oceans, greater humidity in the atmosphere and overwhelmed, aging drainage systems. “Increased moisture in the air and unusually heavy rainfall are classic signals of climate change. As the world warms, storms are able to feed on warmer ocean waters, and the air is able to hold and dump more water. These trends have led to a pronounced increase in intense rainfall events and an increase in flooding risk. In the Southeastern US, extreme precipitation has increased 27 percent from 1958 to 2012.”
Did you know only 10% of these recent losses were covered by flood insurance? Statistics for flooding make major assumptions that the climate of the past is the same as the climate of today, and that’s no longer a very good assumption. The old reasons for not buying flood insurance – It doesn’t flood here, it hasn’t flooded in 40 years, the flood map says low risk-no longer apply.
It’s time to re-think the flooding myths and measurement of the past and recognize the changes we see in our weather patterns. Katharine Hayhoe, a climate researcher at Texas Tech University, told The Washington Post. “We buy a house outside the 100-year flood zone, believing that means we’re safe; we expect our storm sewer drains and our levees to protect us from all but the rarest extremes. We fail, however, to account for how these extremes are rapidly becoming more frequent in a changing climate.”
Wherever it rains, it can flood. Be realistic and responsible about your actual flood risk. Count on the weather to be unpredictable —and increasingly more extreme.
