The Bloomberg Carbon Clock

The Bloomberg Carbon Clock tracks the level of CO2 in the atmosphere measured in parts per million. In mid-May the number exceeded 414 parts per million [ppm]. The number up-to-the- second can be found at: https://www.bloomberg.com/graphics/carbon-clock/.

From the website comes the following observations based on graphs presented on their website:

• “The higher the number climbs over time, the greater the risks from climate change. When the U.S. started measuring airborne CO2 in 1958, it stood at 316 ppm.

• “Don’t be fooled when the CO2 level falls each year between May and October. That’s when vegetation in the Northern Hemisphere absorbs carbon from the air. At summer’s end, the carbon levels climb back up. For decades, the lowest CO2 level of any given year has been higher than the year before. So in the long run……even when CO2 is going down, it’s going up.

• “The CO2 level is now around 400 ppm [the number in mid-May 2020 exceeds 414 ppm]. The danger zone? 450 ppm, which we may hit by 2040. Beyond that, the warming Earth and its inhabitants will likely experience extreme weather events, increased sea-level rise, and their consequent ecological and economic impacts.”
