I’ll get back to dissecting renewable fuels shortly, but I thought I’d share with you the reading of Mauna Loa’s CO2 concentrations for Dec. 31, 2015. It was 402.07.
That total in and of itself does not mean much. It has been much higher in the past and much lower more recently. Most plants would express pleasure in the new total if they were capable of doing so. Most climate scientists feel the opposite.
What gets my attention is the fact that it grew 3.05 ppm in one year. It has jumped that much on more than one occasion since 1959, but certainly not often. In recent years it has tended to grow about 2.25 ppm per year.
When I couple that observation with the fact that emissions did not grow at all in 2014, it bothers me.
It doesn’t panic me. It doesn’t make me change my perceptions of the climate debate or the climate itself. I still have a Lukewarm view of sensitivity, temperature and sea level rises and impacts on our planet.
But I confess that it bothers me.
