Due to the shutdown 2018's numbers aren't down from NOAA.  Estimate put's 2018 at 408.50 ppm.  That's an increase of only 1.95 ppm over 2017.  Thanks to the super NiƱo, 2016's growth over 2015 was 3.4 ppm.

2019 will also be the first yearly average above 410 ppm.  August, September & October 2019 may be the last months to average below 410 ppm.

I have to believe that number will be corrected lower eventually!

It's 1 ppm higher than the high recorded in May and May averages are generally 4 ppm higher than January averages.

The Scripps hourly data for the 12th is too noisy for them to record a daily data point for the Keeling Curve. Let's see what tomorrow brings.
