In October 2018, a week after his daughter’s birth, Gan Golan received some stunning news: the Blue Planet had a deadline. The Intergovernmental Panel on Climate Change had just published a report saying global warming would soon surpass [1] 1.5 C, a critical threshold [2].
This news felt personal to Golan, a new father; he wanted the Earth to remain a safe place for his daughter. He wanted to shout from the rooftops that the planet is rapidly approaching a point where climate change would cause irreversible [3] damage, and that we should act now to reverse course. To shift public awareness and prompt [4] action, Golan launched a project with activist Andrew Boyd: the Climate Clock.
In September 2020, the clock first appeared in Union Square, New York City. Above ordinary stores like Best Buy and Nordstrom Rack, a string of giant digital numbers overlook the streets, displaying the years, days, hours, minutes, and seconds left before global warming would reach a 1.5 C mark. This timeline is calculated based on carbon budget estimates to limit the planet’s temperature rise to 1.5 C, and the annual rate at which we burn through these budgets.
Golan and Boyd’s project represents a critical window for action. Research suggests that a 1.5 C increase in the planet’s average temperature will wipe out coral reefs, significantly increase the number of severe thunderstorms, and flood cities with melted ice.
While the clock has elicited [5] mixed public responses, it also offers a glimmer of hope. In April 2021, the two activists decided to add a second set of numbers to the clock, tracking measures to counter climate change, such as the percentage of global energy generated from renewable sources. Today, the clock hangs in Seoul and Glasgow as well, inspiring and informing onlookers.
