The Climate Clock digital display reads "Earth" plus sign "Democracy", One Union Square South, New York City, October 6, 2024. Co-created by Andrew Boyd and Gan Golan, Climate Clock debuted in September 2020 and was adapted from a public art installation called Metronome, created by Kristin Jones and Andrew Ginzel. Climate Clock typically counts down the amount of time-less than 4 years when this photograph was made-that scientists estimate remains for humanity to take drastic actions that can prevent average global temperatures from rising an additional 1.5 degrees Celsius. Climate Clock also displays additional messages such as this one.
