With the unusual amount of flooding impacting Nebraska and Iowa along the Missouri and Platte Rivers, the National Center for Atmospheric Research says the U.S. Army Corps of Engineers did not plan accordingly.
Kevin Trenberth with NCAR says a lot of structures built, including levees and dams, are based upon past records obsolete because of climate change.
Trenberth says unusual patterns caused by a “La Ninia” has caused an unusual amount of heavy snows in neighboring states that have compounded the flooding situation.
“La Ninia” is part of a cycle that occurs every 3-7 years when it’s much colder than normal in the Eastern and Central Tropical Pacific. Trenberth says this event influences the heating patterns in where all activity occurs in the Pacific.
Trenberth says those heating pattern changes influences the jet streams and storm tracks across the Americas.
Trenberth says the Corps of Engineers is not a scientific organization, typically working on past weather events.
