The clock shows a continuous countdown of the time remaining before we breach the 1.5 and 2°C climate targets (you can see the clock online at: www.countdown2degrees.com), with the aim of putting the urgency of the climate challenge clearly into the public consciousness.  Every year the clock will be stopped and re-set based on the latest scientific data; we can add time to the clock, but only if we work collectively and measure our progress against the targets that we have set for ourselves.
