Alarming Study Reveals Potential Threat From 'City-Killer' Asteroids

According to a report from NASA and researchers at Tulane University, New Orleans is sinking at a rate of one to two inches per year, significantly exacerbated by human intervention. The city's unique landscape, formed from Mississippi River sediments, has been threatened by rising sea levels and increased flooding risks.
Scott Ploof, writing for Big Easy Magazine, explains that while natural land compression occurs over time, construction of flood control levees has interrupted sediment deposition needed to counteract subsidence. This disruption, coupled with the effects of climate change, has increased the rate at which the ground is sinking.
The Intergovernmental Panel on Climate Change (IPCC) forecasts sea levels rising between 1.4 to 2.8 feet by the century's end, with worst-case scenarios suggesting increases of nearly seven feet. Such changes pose significant threats to coastal cities like New Orleans, already vulnerable to flooding from hurricane storm surges.
In response, Tulane University has received a $3.2 million grant to study the impacts of sea-level rise on military installations globally, aiming to inform future remediation efforts in affected areas.
