How long until it’s too late to save Earth from climate disaster? This clock is counting down.

How long does the world have left to act before an irreversible climate emergency alters human existence as we know it? A new digital clock unveiled in Manhattan’s Union Square over the weekend promises to tell you — down to the very second.

The Climate Clock unveiled by artists Gan Golan and Andrew Boyd warned at 1:30 p.m. Monday that there were 7 years, 101 days, 17 hours, 29 minutes and 22 seconds until Earth’s carbon budget is depleted, based on current emission rates. A total depletion would thrust the world into further turmoil and suffering through more flooding, more wildfires, worsening famine and extensive human displacement, according to the artists.
