    @Killian, #199

    ” I don’t see how this pattern could come from anything other than natural emissions.”

    Uhm, if so, just talk to some clever designers.

    What must we do?

    To Killian: we are in agreement. I think we are seeing atmospheric CO2 continue to climb and present anomalies. I think a significant part of the increase we are seeing since 2016 is related to changes in the natural carbon cycle of the planet that has gotten a bit warmer.

    May CO2

    May 2019: 414.83 ppm
    May 2018: 411.30 ppm

    3.53 ppm increase is higher than we would like to see.

    Cheers

    Mike

    Nemesis @200, Russel’s comments and website look like they are satire to me, ie: don’t take it at face value, and read between the lines.

    UAH has posted the June global TLT anomaly at +0.47ºC, the warmest anomaly of the year-to-date (May was the coolest anomaly of the year-to-date). It is the 2nd warmest June in the UAH TLT record behind 1998 (+0.57ºC) and ahead of 2016 (+0.33ºC), 2010 (+0.32ºC), 2015 (+0.31ºC), 1991 (+0.31ºC), 2002 (+0.30ºC), 2014 (+0.25ºC) & 2017 (+0.22ºC).
    June 2019 sits at =17th warmest month in the UAH TLT all-month record.
    With the first half of the year behind us, 2019 sits firmly in the top-five warmest years and perhaps likely to end up placed 3rd the behind big El Niño years 2016 & 1998.
