I was born in 314 parts per million of Carbon Dioxide, my children were born in 345 ppm CO2 , and my granddaughter is born in 409 ppm.
The most commonly used definitions of time are expressed in eras. Recently I have seen more and more that environmentally conscious people use the concentration of CO2 in the air as a time indication. I think it’s a good idea we all use our date of birth from this calendar … to raise awareness
It is a good method to make it clear to everyone that this concentration is continuously increasing and can therefore even be used as a time indication. This calendar can also be a tool to make everyone aware of the changing conditions in the relatively small layer of the atmosphere around the earth.
I will not write about why and by whom … The World Wide Web is full of stories about the current climate crises.
