Climate change Solutions Summit 

In October 2016, Delaney had the great honor of introducing Former Secretary of State and 2016 Presidential Candidate, Hillary Clinton, and Former Vice President and the founder of The Climate Reality Project, Al Gore, at their Climate Change Solutions Summit, held at Miami-Dade College, in her hometown of Miami, Florida. 

Miami March For Science 2017

Scientists, teachers, students, and parents all joining arms with activists to march through the streets of cities all over the world for a single cause – science. That’s precisely what happened on Earth Day 2017 in Downtown Miami as thousands gathered for the inaugural March For Science Miami to support scientific research and evidence-based facts at an event that Delaney co-conceived and acted as Executive Outreach Coordinator and host. 


The chant that echoed down Biscayne Boulevard from a power-packed rally at Museum Park, “Science, not Silence… Science, not Silence,” was broken only by a cacophony of horns and hollers of supportive passersby. An endless mix of Thomas Dolby’s 1982 hit, “She Blinded me with Science,” blared from more than a few Bluetooth boom boxes on wheels. The well-mannered but determined crowd ultimately landed at the Miami-Dade County Government Center for a huge Science Expo that lasted all afternoon on this glorious and successful day for science enthusiasts and practitioners. 

South Miami's & Florida's Historic Solar POwer Law 


When Delaney learned that the City of San Francisco had enacted a law requiring that the maximum amount of solar power possible was required on all new homes and material renovations she instantly knew that Florida, a place nicknamed The Sunshine State, needed such a law. San Francisco’s law (click here for a copy of their Ordinance) intrigued her and led Delaney to write a letter to a dozen local Mayors requesting that they consider implementing a similar law in their municipality. 

Visionary Mayor Phil Stoddard of the City of South Miami, a resident of a solar powered home himself, was quick to respond and offered his support under one condition: that Delaney help him author the law. Their first meeting lasted nearly six hours, but it also laid the foundation of the Ordinance the South Miami City Commission passed with a 5-0 vote upon its first reading in May 2017 (Click here for the draft of the ordinance) and with a 4-1 vote upon its final reading in July 2017. The Solar Mandate became law in the City of South Miami in September 2017. 

The law mandates that any new construction of a house or material renovation of an existing home must install the maximum amount of solar panels on its roof. 

This historic law makes the City of South Miami the first City in the State of Florida and Florida the second State in the United States to have such a law and holds the promise that South Miami will lead the State of Florida into our sustainable future by turning the Sunshine State into Delaney's dream that we one day become THE Solar State. 

Florida'S Landmark Constitutional Climate Lawsuit

Reynolds V. State of Florida


On Monday April 16th 2018 Delaney became the lead Plaintiff in a lawsuit against Florida Governor Rick Scott and the State of Florida (click here to read the lawsuit) in a project she'd been working on for three years. Along with seven other brave children from all over Florida, the lawsuit seeks to have the promises made in the Florida Constitution and The Public Trust Doctrine kept and that our Public Trust Resources including our atmosphere and waters be protected from man-made carbon dioxide pollution caused by burning of fossil fuels. Delaney and her friends believe that the State of Florida and its current Governor and his Cabinet, the Legislative and Executive branches of the government, have failed to uphold their duties outlined in the Florida Constitution and Public Trust Doctrine that obligate them to protect our natural environment and thus they have turned to the Judicial branch to bring climate justice to the State. 


Delaney is joined by seven amazing co-Plaintiffs, the Floridians standing with her to fight for climate justice including Levi, Isaac, Luxha, Andres, Oscar, Oliver and Valholly. She's also joined by an amazing legal team of lawyers from all over Florida including Guy Burns, Andrea Rodgers, Meg Ward, Caitlin Howard, Dick Jacobs, Mitchell Chester, Sandy D’Alemberte, Wally Pope, Jane West, Erin Deady, Deb Swim, and Matthew Schultz.

Social entrepreneurship & Community Service

The Sink or Swim Project

Founder & CEO

Delaney believes that our planet’s warming climate is the most important challenge that her generation will face in their lifetimes and unless they solve the crisis, the impact to every aspect of society and environment could be catastrophic. That is especially true in South Florida, a community that has been labeled America’s ‘ground zero’ in the global warming war given the risks we face from sea level rise. Trillions of dollars in real estate, the entire region’s tax base, the health and welfare of millions of our residents, and the potential extinction of our environment are at risk during her lifetime if we do not solve this dire problem. We simply do not have a day to waste in educating our community about the problem and solutions.

Given the magnitude of these problems and her concern for our future, Delaney founded an NGO, The Sink or Swim Project, as a device to educate people about the risks our community and the world faces, as well as the solutions that we must embrace in the future if we are to solve this crisis. She gives presentations and lectures to groups ranging from elementary through high schools, colleges, and adult organizations. She is also deeply involved in political advocacy and lobbying on a wide range of climate and environmental issues at the heart of South Florida’s existence.

She has shared her message in live lectures to tens of thousands of people, distributed over 20,000 of her comic books, has had her written and video work viewed by nearly 200,000 people on social media, and has been seen by millions of people on television.

Meet The Teen Trying To Keep Miami From Going Underwater

By: Julie Zeilinger, MTV News

By age 13, Miami Native Delaney Reynolds had published her third in a series of children’s book about Floridian ecology. But what started as a project to enlighten young people about the beauty of Miami's coastal environment turned into a somber realization about that environment's expiration date. Reynolds’ research led her to learn about “sea level rise,” the harrowing reality that while the levels of our seas have been stable for thousands of years, they've risen about 10 inches in the past century alone.

That may not seem like much, but this is already causing increased flooding and altered shorelines along coastal cities like Miami, Boston, and New York. And if things continue at this rate, sea levels could rise as much as 10 feet by the end of the century. The city of Miami could be underwater by 2100, and up to 2.5 million Miami residents could become climate refugees.


An Inspiring Environmental Education

By: Delaney Reynolds, Community News Coral Gables

With high school graduation a few weeks away I’ve been thinking a lot about my experiences in the classroom as well as what I’ve learned while exploring our magnificent environment and the challenges that our ecology and society will face in my generation’s future. I’ve been fortunate to have hiked to the top of a volcano in the Andes Mountains, swam with Giant Manta Rays at night in Hawaii, chased White Tip Sharks over a coral reef in the Galapagos, slept under a sky illuminated by millions of stars in the Everglades and on an Indian Reservation in South Dakota, and watched lions, elephants, and giraffes roam in the wild while on safari in Africa.

And along the way I’ve been inspired by my teachers, the people I’ve met around the world, my family and friends here at home and most certainly the things I’ve seen in our beautiful, natural world, especially those related to the water. Whether the marshes of the Everglades and our colorful coral reefs, or our sandy shores and whimsical mangrove habitats, it is the water that always touches my soul.

8 Young Environmentalists Working to Save Earth

By: Helaina Hovitz, Teen Vogue

Delaney grew up surrounded by water, splitting her time between her modern city and a remote, 1,000-acre island that housed just 43 solar-powered homes. In third grade, her class collectively wrote a book, Laws of the Universe, that inspired her to learn more about the environment she came to love so much.

She continued to research issues like rising sea levels and gradually learned about climate change and the significant threat that rising oceans pose to South Florida, and began to interview local political leaders, climate scientists, business owners, and others being impacted by sea rise or working on solutions to help them. Our planet's warming climate, she says, is the most important challenge that our generation will ever face.

"This Is Not A Partisan Issue": Here's What Participants In "March For Science" Had To Say

By: Amanda Rabines, WLRN Miami

Thousands participated in Miami’s “March for Science” on Earth Day and walked down Biscayne Boulevard wearing lab coats and holding up signs with rising seas, periodic table elements and vaccine shots.

They rallied in unison with the marches around the nation - fueled by threats coming from the White House to cut federal funding from agencies like the National Institutes of Health and the Environmental Protection Agency (EPA).
