We all now know that the global average temperature passing the threshold of 2°C is the point where really bad things start to happen, and it becomes much more difficult to slow down the devastating effects of climate change.
But, if you look online and in the media, it’s very hard to find a good reference for when 2°C will actually happen. Presently, the 2°C target floats abstractly in the public mind. The Countdown 2° Clock acts as a public line in the sand which says, “This is the date.” It will act as a measuring stick by which we can evaluate our progress.
Each year, a week before Earth Day (April 22), the clock will be stopped. A group of leading climate scientists from around the world will evaluate the latest data. Then, on Earth Day, they will restart the clock with a new time. We will be able to see how we are doing in relation to 2°C. Have we gained or lost time?
Humanity has the power to add time to the clock, but only if we work collectively and measure our progress against defined targets.
