By now, humanity should know that the clock is ticking on climate change. Without a literal clock ticking away in our faces, however, we seem to conveniently forget. That’s why artists Gan Golan and Andrew Boyd installed a climate clock in Manhattan’s Union Square, 10 stories high for everyone to see.
On September 17, the clock began counting down from seven years, 103 days, 15 hours, 40 minutes, and seven seconds. When the clock runs out, the average global temperature will be 2.7 degrees Fahrenheit above industrial levels, if greenhouse gas emissions remain the same, and we face irreversible climate disaster.
