COVID and CO2

We have heard a lot about how you can see now see the Himalayas and air pollution has gone down markedly.

However a few stats from the Guardian’s “Green Mail”:

Weekly average CO2 readings

1) 1 March 2020: 413.84 ppm
Last year: 411.91 ppm

2) 29 March 2020: 415.74 ppm
Last year: 412.39 ppm

3) 18 April 2020: 416.27 ppm
Last year: 413.62 ppm

4) 25 April 2020: 415.88 ppm
Last year: 413.71 ppm

5) 16 May 2020: 416.79 ppm
Last year: 415.31 ppm

6) 23 May 2020: 416.97 ppm
Last year: 414.72 ppm

Despite the reduction in economic activity and visible pollution, CO2 readings are still up on last year.
