Date: 07/29/25Time: 7:00pm - 8:30pm
Branch: Miller Branch
Age group: Adults, Everyone
Program type: History & Genealogy
Description:
“Powerful … Tidwell is an excellent reporter whose hyperlocal focus shines light on how the climate crisis shapes the lives of ordinary individuals. This will stick with readers long after they finish the last page.”
― Publishers Weekly, starred review
Join us for an evening with author Mike Tidwell as he discusses his new book, The Lost Trees of Willow Avenue.
A riveting and elegant story of climate change on one city street, full of surprises and true stories of human struggle and dying local trees – all against the national backdrop of 2023's record heat domes and raging wildfires and, simultaneously, rising hopes for clean energy.
In 2023, author and activist Mike Tidwell decided to keep a record for a full year of the growing impacts of climate change on his one urban block right on the border with Washington, DC. A love letter to the magnificent oaks and other trees dying from record heat waves and bizarre rain, Tidwell's story depicts the neighborhood's battle to save the trees and combat climate change: The midwife who builds a geothermal energy system on the block, the Congressman who battles cancer and climate change at the same time, and the Chinese-American climate scientist who wants to bury billions of the world's dying trees to store their carbon and help stabilize the atmosphere.
No book has told the story of climate change this hyper local, full of surprises, full of true stories of life and death in one neighborhood. The Lost Trees of Willow Avenue is a harrowing and hopeful proxy for every street in America and every place on Earth.
Mike Tidwell is a journalist, author, and climate activist living in Takoma Park, MD. His most recent book is a detailed examination of the dramatic impacts of global warming in his own front yard, called The Lost Trees of Willow Avenue: A story of Climate and Hope on One American Street. Mike’s previous six books include Bayou Farewell (2003) about the disappearing wetlands of south Louisiana and The Ponds of Kalambayi (1990), a Peace Corps memoir. As a past contributing writer for The Washington Post, he won four Lowell Thomas Awards, the highest prize in American travel journalism. He is a former National Endowment for the Arts fellow whose work has been published in Audubon, National Geographic Traveler, Orion, Washingtonian, and elsewhere. A passionate conservationist, he founded the Chesapeake Climate Action Network in 2002, where he has led local and national campaigns for clean energy. He lives on Willow Avenue in Takoma Park, MD with his wife Beth and their cat Macy Gray.

This novel focuses on a menacing end of the world as we know it, as seen by two rich New York families who converge on an isolated vacation house. The New York Times' review, when this novel came out in 2020, read, "Alam doesn’t dwell in the specificity of apocalypse, which has been the obsession of writers since the Flood. Instead he lobs a prescient accusation: Faced with the end of the world, you wouldn’t do a damn thing." We'll discuss the book, the climate crisis, and whether we would do a damn thing.
Ask at the customer service desk for a copy of the book, beginning 4 weeks before the discussion date.
