New York Climate Clock just 7 years before irreversible climate change
SEASON 1 – EPISODE 9 – New York Climate Clock just 7 years before irreversible climate change
The New York metronome’s digital clock in Manhattan that told the time now tells the time remaining and it is truly terrifying.
The Climate Clock shows two numbers. The first, in red, is a timer, counting down how long it will take, at current rates of emissions, to burn through our “carbon budget” — the amount of CO2 that can still be released into the atmosphere while limiting global warming to 1.5°C above pre-industrial levels. This is our deadline, the time we have left to take decisive action to keep warming under the 1.5°C threshold. The second number, in green, is tracking the growing % of the world’s energy currently supplied from renewable sources. This is our lifeline. Simply put, we need to get our lifeline to 100% before our deadline reaches 0.
This clock follows the methodology of the carbon clock made by the Mercator Research Institute on Global Commons and Climate Change (MCC) which uses data from the recent IPCC Special Report on Global Warming of 1.5°C. The report states that starting from 2018, a carbon dioxide budget of 420 Gt of CO2 gives us a 67% chance to stay under 1.5°C of warming.
“The concept of the carbon budget is based on a nearly linear relationship between the cumulative emissions and the temperature rise. Nevertheless, this does not mean that the earth would necessarily be 1.5⁰C warmer at the very point in time when the remaining carbon budget for staying below the 1.5⁰C threshold was used up. This is due to, among others, the fact that there is a time lag between the concentration of emissions in the atmosphere and the impact thereof on the temperature”.
