“When Sandy hit, New York City had zero coastal protections,” says Daniel Zarrilli, special advisor for climate and sustainability at Columbia University…”I credit Sandy as that pivotal moment that not only launched billions of dollars of resilience investments across the city…It also provided the spark for a whole range of other climate policies…”

Gigantic tsunamis have been decimating coastlines since time immemorial. We ignore these prehistoric warnings at our own peril.

A boulder weighing more than 40 tonnes sits on the sand high above the ocean. Dwarfing every other rock in view, it is conspicuously out of place. The answer to how this massive outlier got here lies not in the vast expanse of the Atacama Desert behind it but in the Pacific Ocean below…

No debate anymore: Climate change makes extreme weather worse, federal scientists say – WUSF Public Media

Scientists at the U.S. National Oceanic and Atmospheric Administration (NOAA) delivered a clear message: Climate change is — unequivocally — making extreme weather events worse.
South Florida has always been hot, rainy and vulnerable to hurricanes. So it’s understandable that some longtime residents remain skeptical that climate change is doing anything to make the region’s age-old problems any worse…

On the Coast: Before and After the Parade of Atmospheric Rivers – Planet Snapshots issue 59 via Medium

California is left drenched, flooded, and perhaps a little hopeful after recurring atmospheric rivers pummeled the state for 2 weeks straight. The rains are a small reprieve for the area’s years-long drought. But the sheer volume of rainfall was much more than the parched landscape could handle. With a turn of the faucet, the state went from too dry to too wet in what’s called a “weather whiplash,” transforming the Golden State to shades of brown…

Global Weather Patterns and Coastlines

Coasts are sensitive to sea level rise, changes in the frequency and intensity of storms, increases in precipitation, and warmer ocean temperatures. In addition, rising atmospheric concentrations of carbon dioxide (CO2) are causing the oceans to absorb more of the gas and become more acidic. This rising acidity can have significant impacts on coastal and marine ecosystems.

The impacts of climate change are likely to worsen problems that coastal areas already face. Confronting existing challenges that affect man-made infrastructure and coastal ecosystems, such as shoreline erosion, coastal flooding, and water pollution, is already a concern in many areas. Addressing the additional stress of climate change may require new approaches to managing land, water, waste, and ecosystems…

Atmospheric rivers hitting California will become even more intense. Here’s how they work – the San Francisco Chronicle

The same weather that replenishes California water supplies could bring the next megaflood.

A procession of storms is drenching Northern California this week, with rainfall already topping 2 inches in San Francisco and surpassing 8 inches in the Santa Cruz Mountains. More precipitation is on tap through the weekend, prompting concerns of widespread urban flooding and potential landslides…
