California’s Coastal Harbors, Beach Compartments and Sand Dredging; By Gary Griggs

Every year the dredge at the Santa Cruz Small Craft Harbor along central California’s northern Monterey Bay sucks up about 250,000 cubic yards of sand, on average, from the entrance channel and pumps it out onto Twin Lakes Beach where it continues its journey down coast. If it were put in dump trucks, it would fill about 25,000 of them, but the waves can move all that sand without any human labor, and without any noise or carbon emissions.

The US would suffer some of the biggest costs of climate change

Climate change is a classic tragedy of the commons: every country acting in its own self-interest contributes to depleting a joint resource, making the world worse for everyone. The social cost of carbon (or SCC) is a way to put a price tag on the result of that tragedy, quantifying just how much climate change will cost the world over the coming generations.

As sand mining grows, Asia’s deltas are sinking, water experts warn

Sand mining from rivers is depriving many low-lying Asian deltas of the sediment they need to maintain themselves, raising the risk of worsening land loss to sea level rise, researchers say.
