A giant climate clock lit up at the Metronome in Prague’s Letná district on Tuesday evening. The eight-meter-high and 35-meter-wide pointers show the time left to avert irreversible climate change, as reported by Climate Clock.

The Festival of Freedom group commissioned the clock, which will be in operation until December 12. Prague is the first European city east of Berlin to install the Climate Clock.

Unless global greenhouse gas production is significantly reduced, the world will be less than seven years from irreversible climate change. Citing the latest scientific calculations, the event organizers said.

Two luminous dials at Letná remind us of the time remaining until the planet warms up by 1.5 degrees Celsius. The left shows the remaining years and days, and the right counts the hours, minutes, and seconds.

Studio Multiverse is behind the design of Prague’s Climate Clock. The installation was created with the lowest possible ecological burden in mind. The clock consumes as much electricity as a single domestic stove.

The Climate Clock already measures time in New York, Rome, Seoul, and Glasgow. Prague is the first European city east of Berlin to have a climate clock.

The clocks were placed on Letná by the Festival of Freedom, a group of independent civic initiatives and organizations organizing events to mark the anniversary of November 17. According to the group, the climate crisis represents one of the most significant threats to freedom, peace, and democracy in the Czech Republic. In a petition called “3 Steps in 3 Years,” they called on MPs to address the climate issue along with education reform and aid to Ukraine in the face of Russian aggression.
