The Mauna Loa Carbon Dioxide Observatory Added 424 ppm to the Graphic of Daily Readings.
I wonder why that is...
Trends in Atmospheric Carbon Dioxide
Nineteen years ago, when I first started writing at DU, carbon dioxide concentrations measured at the Mauna Loa Observatory were 372.68 ppm. I'm not sure what the corresponding graphic showed as the upper number on the ordinate, but I don't think it was 424 ppm.
Over the years I was continually informed here - although I never actually believed it - that solar and wind energy would save the day.
Tell me, is the day saved?
