As Miami Battles Sea-Level Rise, This Artist Makes Waves With His 'Underwater Homeowners Association'

Miami artist Xavier Cortada lives in a house that stands at six feet above sea level. The Episcopal church down the road is 11 feet above the waterline, and the home of his neighbor, a dentist, has an elevation of 13 feet. If what climate scientists predict about rising sea levels comes true, the Atlantic Ocean could rise two to three feet by the time Cortada pays off his 30-year mortgage. As the polar ice caps melt, the sea is inching ever closer to the land he hopes one day to pass on to the next generation, in the city he has called home since the age of three.


"It is with incredible pain that I say I know my city is doomed by climate change," said Cortada, who is the artist in residence at Pinecrest Gardens, a recreation center a few blocks from his home in South Miami. "But as a Miamian, my job is to do everything I can to help us through this chaos."

That explains the big sign in Cortada's front yard. In watery blues and greens, it displays the property's elevation with a bold number 6. It's also why the artist has invited other residents of this upscale district to join his wryly named Underwater Homeowners Association project. Across the community, elevation markers designed by Cortada are now standing in front of his neighbors' homes and businesses—a colorful, albeit painful, reminder of what's at stake.

"The underwater markers are basically me trying to let people know that Antarctica is coming to town," said Cortada, who has traveled to both the southernmost continent and the North Pole to witness the rapidly melting glaciers that are contributing to the rise of ocean levels around the globe. In a converted laboratory in Antarctica and on the pitching deck of a Russian icebreaker in the Arctic Ocean, he created more than 100 paintings out of glacial meltwater mixed with paint and sediment from Antarctic mountain ranges.

Cortada wants to use the elevation markers to get neighbors talking about the changing climate and its effects on their lives and homes by mapping the destruction and chaos in advance. "The residents of Florida are at ground zero when it comes to sea-level rise," he said. "Unfortunately, our politics and mind-set don't reflect that we need to do some serious problem solving. I wanted to create a way of helping us understand that, by making the invisible visible and just a little bit strange."

The Underwater HOA project launches this month during Art Basel Miami Beach, an annual festival that draws art lovers from all over the world. Miami is already feeling the consequences of sea-level rise in the form of widespread flooding during storm surges and seasonal king tides.

"The reason I know we can do something about this is that we've done it before," he said. "Everybody from Miami could tell you their hurricane stories, when neighbors come together like they never have before. That sense of community and purpose when there's a problem in front of us—it's something we know how to do. With sea-level rise, it's an existential problem."

As part of the artist's multifaceted project, high school students have painted huge versions of Cortada's elevation markers on the pavement of intersections along Pinecrest's main thoroughfare. At Pinecrest Gardens, the artist will also be exhibiting a selection of 60 his "Antarctic Ice Paintings" that have never been seen before. He made these haunting abstract compositions with ice samples from the Ross Sea and fragments of earth gathered by climate scientists nearby in the McMurdo Dry Valleys.

The combination of community activism and striking artistry is typical of Cortada, said Barbara Matilsky, curator of art at the Whatcom Museum in Bellingham, Washington, who has included his work in two exhibitions. "The 'Antarctic Ice Paintings' are a beautiful idea—they physically embody the continent, so that we have a remnant of Antarctica in the museum—but they are also very beautiful visualizations" to look at, she said.

Matilsky also admires how Cortada's projects have raised awareness and galvanized action on climate issues. For his Reclamation Project, launched in 2008, he persuaded merchants in Miami Beach's trendy Lincoln Road district to care for mangrove seedlings grown in planters outside their shops. After being on public display for a month and a half, the mangroves were transplanted by volunteers along the shore of Biscayne Bay, where they act as natural barriers against storm surge. The project was such a success that it was adopted as an ongoing program by Miami's Frost Museum of Science. So far, eight acres of mangrove swamp have been created.

The artist hopes he'll reach even more people with Underwater HOA but says he isn't concerned with the actual numbers. "At the end of the day," he said, "I'm just trying to get this conversation beyond a whisper."

Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged more than $1 trillion over the next seven years to address the crisis of a rapidly heating planet.

In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.

With eight million metric tons of plastic entering the world's oceans every year, there is growing concern about the proliferation of plastics in the environment. Despite this, surprisingly little is known about the full impact of plastic pollution on human health.

But a first-of-its-kind study released Tuesday sets out to change that. The study, Plastic & Health: The Hidden Costs of a Plastic Planet, is especially groundbreaking because it looks at the health impacts of every stage in the life cycle of plastics, from the extraction of the fossil fuels that make them to their permanence in the environment. While previous studies have focused on particular products, manufacturing processes or moments in the creation and use of plastics, this study shows that plastics pose serious health risks at every stage in their production, use and disposal.

Air pollution within the home causes 3.8 million deaths a year, according to the World Health Organization. A recent University of Colorado in Boulder study reported by The Guardian found that cooking a full Thanksgiving meal could raise levels of particulate matter 2.5 in the house higher than the levels averaged in New Delhi, the world's sixth most polluted city.

But soon, you will be able to shop for a solution in the same place you buy your budget roasting pans. IKEA is working on a specially-designed, air-purifying curtain called the GUNRID.
