John Kerry (78) – Aurora, Colorado

John Kerry has proved himself worthy of the United States’ citizenship in more ways than one. Aside from the fact that he courageously participated in the “Winter Soldiers” hearing on American War Crimes in Vietnam, the American politician, diplomat, and the attorney has served the nation for decades now with a particular emphasis on climate change.

His support helped engineer the passage of financial reform and health care bills in the United States. In 2021, he became the first special presidential envoy for the climate in the Biden Presidential administration, and in 2022, he was already focusing on other smaller countries’ climate change differences.
