Quick sand, dirty Money; South Africa

Mining has already cut coastal sand supply by as much as 70 percent in the municipality of Ethekwini, which includes Durban. Each year, miners dig up more than 400,000 cubic meters of sand from Durban’s rivers, enough to fill 160 Olympic swimming pools. This sand would normally be deposited on beaches and help offset coastal erosion. At current mining rates, Durban’s beaches are predicted to contract, on average, by more than a meter each year.

Eyes on the Coast—Video Cameras Help Forecast Coastal Change

Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or disappear depends in part on what happens just offshore. If we understand these processes, scientists can include them in computer models of coastal change that can be used to forecast future changes over years, decades, or even centuries.

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.

DON’T LET TRUMP AND PRUITT TURN ALASKAN WILDERNESS INTO WASTELAND: NRDC Petition

There’s a new front in President Trump’s war on our environment: Alaska’s spectacular Bristol Bay. And if we don’t stop them, the resulting pollution and environmental destruction would be a catastrophe for the wildlife and communities that call Bristol Bay home.

Florida without its beaches: Seawall dooms state oceanfronts, By Robert Young

The Florida Department of Environmental Protection issued an emergency authorization last week that will allow individual property owners in a portion of St. Johns County to build new seawalls without the typical engineering and scientific analysis. This is a terrible mistake for the communities impacted. It is poor coastal management.

What Harvey means for future storms across the nation; Op Ed By orrin H. Pilkey

Forewarning about the path and future disastrous evolution of Hurricane Harvey proved to be quite accurate. Hurricane Harvey may be an example of the long-predicted intensification of storms resulting from the warming of the seas.

Column: High-rises spell the end for Florida beaches; By Orrin H. Pilkey and J. Andrew G. Cooper

Floridians are becoming more attuned to sea level rise and more familiar with nuisance flooding related to the rising sea. However, we believe there is less recognition that by century’s end it is likely that most of Florida’s major beaches will be permanently gone.

An Evaluation of the Ongoing Impacts of Sand Mining at the CEMEX Lapis Sand Plant in Marina, California on the Southern Monterey Bay Shoreline; By Robert S. Young, PhD

The City of Marina commissioned this report to assist in its management and decision‐making for coastal property and resources within the City’s jurisdiction. This report provides a review and synthesis of available documentary information and scientific literature addressing the impact of current sand mining activities within southern Monterey Bay.

The great climate silence: we are on the edge of the abyss but we ignore it

Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual. So today the greatest tragedy is the absence of a sense of the tragedy.
