Two years after a long-lasting undersea heat wave scalded large sections of the Great Barrier Reef, scientists have found that because so many corals died, much of the reef has probably been altered “forever.”

“What we just experienced is one hell of a natural selection event,” said Terry Hughes, director of the Australian Research Council Center of Excellence for Coral Reef Studies at James Cook University in Queensland. ...

For years, scientists have been tracking a large accumulation of floating trash, mostly bits of plastic, in the north Pacific ocean called the “Great Pacific Garbage Patch,” or the “trash vortex.” This region, according to the latest research, has more lost and discarded plastic inside it than previous surveys suggested—like, a lot more. And it’s still growing. ... Read more about The Great Pacific Garbage Patch Has Way More Trash Inside It Than We Thought

Due to rising sea levels, storms will make it more likely that the Port of Long Beach’s wharves will be damaged, critical roads submerged and utilities harmed, bringing activity at one of the state’s economic hubs to a disruptive lurch, experts say.

And to some extent, it’s inevitable, Rick Cameron, the director of environmental affairs and planning at the port, said Friday at the Aquarium of the Pacific during a joint hearing of the Assembly’s Select Committee On Sea Level Rise And The California Economy and the Select Committee On Ports. ...

As the demand for freshwater and energy increases in San Diego County and Northern Baja, the fresh water supply continues to shrink while energy generation remains heavily dependent on fossil fuels. Due to these opposing trends in supply and demand, it becomes increasingly imperative to identify solutions that move these communities to their preferred state in which they are largely reliant on renewable energy and use water sustainably. Large-scale energy solutions include wind power, one of the must abundant sources of energy in these regions. ... Read more about Geodesign Session 5 Road Map
