*****

It wasn’t too long ago that we were talking about atmospheric CO2 crossing the key 400 parts per million threshold. That was 2014. But now, just three years later, atmospheric levels of this key heat-trapping gas are climbing to within striking distance of another, and still more dangerous, atmospheric milestone. 410 ppm.

That’s an increase in the peak atmospheric CO2 value of around 3 ppm per year or more. One that gibes with record annual rates of atmospheric accumulation of this heat trapping gas during 2015 and 2016. And as we approach a new high water mark for…
