Ancient storms could have hurled huge boulders, scientists say – raising new concerns of rising seas
An international team of researchers has come up with a new theory to explain how two giant boulders could have made their way atop a cliff on the Bahamian island of Eleuthera. They suspect it has something to do with the Atlantic Ocean far below them.
Malibu, CA: Broad Beach Sand Project Costs Jump to $55-60 Million Per Decade
The Broad Beach Geologic Hazard Abatement District (GHAD) is now contending with another set of lawsuits over a project originally estimated to cost about $20 million, which is now estimated to cost $55 to $60 million every 10 years. The project will involve bringing in megatons of sand every few years to restore the disappearing beach and dunes.
How cities are defending themselves against sea level rise
Superstorm Sandy and a series of lesser coastal storms since that 2012 disaster compelled some coastal communities to defend themselves by elevating homes and critical infrastructure, building sand dunes, widening beaches and erecting or raising sea walls.

Waiting for the tide to turn: Kiribati’s fight for survival

The only answer to rising seas is to retreat; By Orrin H. Pilkey & Keith C. Pilkey
Except for the timing, there is no controversy among scientists regarding sea level rise. Defending the coast and holding the shoreline in place ultimately will be futile. With a three-foot or a six-foot sea level rise, we will retreat, probably beginning within the next 50 years.
Sea levels to rise 1.3m unless coal power ends by 2050, report says
Coastal cities around the world could be devastated by 1.3m of sea level rise this century unless coal-generated electricity is virtually eliminated by 2050, according to a University of Melbourne new paper that combines the latest understanding of Antarctica’s contribution to sea level rise and the latest emissions projection scenarios.
Rising seas threaten nearly $1 trillion worth of US homes, and most of them are moderately priced
