New York City is sinking under the weight of its skyscrapers, new research shows, which could put its population of more than 8 million people at an increased risk of coastal flooding. [...]
Researchers estimated the weight of all of New York City’s buildings to be around 842 million tons. But to find the areas more vulnerable to sinking — or, as they call it in more scientific terms, “subsidence” — a key factor to consider was the type of soil beneath the buildings.
— The Verge
A new study authored by the United States Geological Survey (USGS) found the city to be sinking at a rate of between 1 to 2 millimeters per year, while parts of Lower Manhattan, Brooklyn, Queens, and Staten Island are subsiding at a rate of 2.75 millimeters. This comes at a time when planning... View full entry
In an effort to mitigate the impending effects of sea-level rise on coastal populations through architecture, UN-Habitat and OCEANIX are once again taking the lead with a new prototype for a floating settlement in the South Korean city of Busan.

As the world heats up and sea levels rise, communities in the U.S. could spend more than $400 billion on seawalls to try to hold the ocean back over the next couple of decades. But there’s a catch: Building a seawall in one area can often mean that flooding gets even worse in another neighborhood or city nearby. — Fast Company
A new paper from The Natural Capital Project at Stanford University that examines how seawalls might impact California's Bay Area was published this spring, adding to a slate of similar scholarship surrounding seawalls that have cropped up in recent years. Other efforts have seen a... View full entry
The City of Miami has published a draft of its Stormwater Master Plan; a $3.8 billion plan to be enacted over the next 40 years, seeking to mitigate the impact of rising sea levels on the city. The plan sets out a wide portfolio of measures, from stormwater pumps and sea walls to more novel... View full entry
Realtor.com has become the first site to disclose information about a home's flood risk and how climate change could increase that risk in the coming decades, potentially signaling a major shift in consumers' access to information about climate threats. [...]
Still, other websites such as Redfin, Zillow and Trulia have no plans to share information about flooding with users [...] say home sellers are reluctant to publish flood risk information, since it could decrease their home's value.

June marks the start of hurricane season on the Atlantic Ocean. Even amidst the ravages of a novel coronavirus and state violence, the perils posed by a heating planet are not going away. If the city turned out to be woefully underprepared for a pandemic, what about measures to protect against storms and floods? — Urban Omnibus
Amy Howden-Chapman, co-founder of the climate change and arts platform The Distance Plan, takes a closer look at a variety of climate impact interventions at New York City's most endangered stretches of coastline: from Lower Manhattan and the Lower East Side, Red Hook, Rockaway Boardwalk, all...

The US has become terrible at building big things, and negligent in even maintaining our existing infrastructure. [...]
That all bodes terribly for our ability to grapple with the coming dangers of climate change, because it is fundamentally an infrastructure problem.
— MIT Technology Review
MIT Technology Review senior editor, James Temple, penned an urgent plea for a renewed, but sustainable, American public works boom that could significantly speed up the painfully slow infrastructure planning process in the face of rapidly changing climate conditions. "To prepare for the climate... View full entry
More than 11 billion tons of ice was lost to the oceans by surface melt on Wednesday alone, creating a net mass ice loss of some 217 billion tons from Greenland in July.
The scope of Wednesday’s ice melt is a number difficult to grasp. To understand just how much ice is being lost, a mere 1 billion tons—or 1 gigaton—of ice loss is equivalent to about 400,000 Olympic-sized swimming pools, the Danish Meteorological Institute said.
— The Associated Press
The Associated Press reports that a summer heatwave that recently scorched Europe has moved north to Greenland, where the elevated temperatures have produced record glacial melt. While 82-percent of Greenland is covered in ice, nearly 60-percent of the island's total ice sheet is showing... View full entry
Venice is full of water, Venice floods, the climate is visibly changing, and sea levels are rising, so you would expect Venice, of all places, to have an official strategy for what to do about it—but you would be wrong. The management plans produced by the City of Venice for Unesco in 2013 and 2018 barely mention the subject and twice, in 2016 and 2019, Unesco’s World Heritage Committee has failed to call them out on this astonishing failing. — The Art Newspaper
"We are used to thinking that, given enough will and money, there is a solution to everything, but this report says that we must get used to the idea that in many cases there will be no solution," writes a frustrated Anna Somers Cocks for The Art Newspaper and explains how a new report by the...

MIT’s Self Assembly Lab and Maldives-based Invena have unveiled Growing Islands, a provocative underwater structural system that redirects wave energy and sand accumulation flows to build new islands and help rebuild existing beaches ravaged by rising sea levels.

While other regions grappled with destructive waves and rising seas, the West Coast for decades was spared by a rare confluence of favorable winds and cooler water. This “sea level rise suppression,” as scientists call it, went largely undetected. [...]
But lines in the sand are meant to shift. In the last 100 years, the sea rose less than 9 inches in California. By the end of this century, the surge could be greater than 9 feet.

In her LA Times long read, Rosanna Xia tells the tale of coastal cities up and down the Golden State and their increasing struggles to defend beaches, infrastructure, and (mostly pricey) properties against the rising sea that relentlessly chews away on a coastline many perceived as permanent...

New York Mayor Bill de Blasio proposed a $10 billion plan to push out the lower Manhattan coastline as much as 500 feet, or two city blocks, to protect from flooding that’s expected to become more frequent as global temperatures rise. [...]
Portions of the extended land would be at 20 feet above sea level. The city can’t build flood protection on the existing land because it’s too crowded with utilities, sewers and subway lines, he said.

New York Mayor Bill de Blasio has unveiled the city's comprehensive plan to increase resilience in Lower Manhattan, a low-lying, highly critical area that has proven to be vulnerable to storm surges and flooding. The newly published Lower Manhattan Climate Resilience Study recommends extending the... View full entry
In Florida, you will see a bewildering mix of optimism, opportunism and denial in the real estate market: luxury condominiums going up in flood-prone South Beach, and property values rising in the vulnerable Keys, post-Hurricane Irma. And though the House of Representatives passed a bill to require real estate agents to disclose flood risks, the Senate has not reviewed it, and a culture of “systemic, fraudulent nondisclosure” persists in high flood risk areas. — The Guardian
As part of her Climate Changed series for The Guardian, Megan Mayhew Bergman investigates the reluctance of Florida's condominium boom (and the wealthy investors behind it) to cool it a bit on new developments in the face of projected climate change-related devastation. "Humans tend to respond to... View full entry
In the language of climate change, “adaptation” refers to ways to blunt the immediate effects of extreme weather, such as building seawalls, conserving drinking water, updating building codes, and helping more people get disaster insurance. [...]
But some researchers are going further, calling for what some call the “deep adaptation agenda.”

Bloomberg's Climate & Environment Reporter, Christopher Flavelle, lays out a range of climate change projections—from the general consensus to the more pessimistic—and how an array of 'deep adaptation' measures could help to mitigate the damage.

Sea level rise and increased rain have posed serious flood risks for Bangkok, the capital city of Thailand, which is already close to sea level. [...]
She works to do this by reclaiming urban porosity through a network of public green spaces. [...]
She has already been planning and working on projects beyond climate resilient housing - including rain gardens, green roofs, permeable parking, urban forests and farms - to address the root causes of increased flooding in her city.
