Tatiana Schlossberg, an acclaimed environmental journalist and the granddaughter of President John F. Kennedy, passed away on the morning of December 30, 2025. She was 35 years old. Her family announced her death through the John F. Kennedy Library Foundation, revealing that she had been battling acute myeloid leukemia since May 2024. Schlossberg was known for her rigorous reporting on climate change and her ability to make complex environmental issues accessible to the public.

Born in New York City to Caroline Kennedy and Edwin Schlossberg, she carried her family's legacy of public service into the realm of journalism. She was a reporter for The New York Times, where she covered science and climate, before publishing her award-winning book, "Inconspicuous Consumption: The Environmental Impact You Don't Know You Have." Her work challenged readers to understand the hidden costs of their daily habits, from the internet to food production.

Schlossberg was diagnosed with a rare mutation of leukemia shortly after the birth of her second child. In a poignant essay published in The New Yorker shortly before her death, titled "A Battle With My Blood," she detailed her grueling treatment regimen, including chemotherapy and stem cell transplants. She wrote with candor about her mortality and her desire to see her young children grow up.

Her passing has drawn tributes from across the media and political landscapes, with many noting her intellect, grace, and dedication to the truth. She is survived by her husband, George Moran, their two children, her parents, and her siblings, Rose and Jack. Her voice remains a significant contribution to the modern environmental movement.
