On the day I was born, 2 February 1954, carbon dioxide concentration in Earth’s atmosphere was approximately 312 parts per million.
Now, on my 71st birthday, CO₂ levels are at 425 ppm and rising fast.
That's an increase of 113 ppm during my lifetime — more than 36%!
By contrast, in the 71 years before I was born, only 21 ppm of CO₂ were added to the atmosphere. Yikes.
I don’t feel much like celebrating today. 😕
