The giant climate clock projected on the side of a building on Guy Street has reappeared.
The clock warns of a 1.5°C and 2°C increase in global temperatures by the year 2034.
According to the Human Impact Lab, global CO2 emissions continue to increase following the observed trend since 2013.
The clock was developed by Concordia University professor and research chair in climate science, Damon Matthews and Canadian musician David Usher. The clock has been projected onto the side of the building for a few days every year since 2016.
The clock’s numbers focus on global carbon dioxide emissions for 2018, the amount of temperature change caused by human emissions and the remaining carbon budget.
The clock displays the following information:

Organizers at the Human Impact Lab are urging Quebecers to sign their online petition to reduce emissions. So far, more than 230,000 people have signed.
The Climate Clock will be on display until December 7, from 4:30 pm to 9:30 pm.
