History of humankind in six frames

  1. Too perfect circle to be real… fact it would have broken down before finish it…. so I wander … human should see the symptoms that the system is wreaking down as the dramatic CO2 report indicated by Alex is proving.

  2. Interesting new website:

    Arctic methane emergency group

    during the 20yy time period CH4 is about 70x stronger GHG than CO2... and about 20 to 25x stronger during 100y period...


  3. Ouch.... Alex, we'll go back to that after Xmas. At least for a few days we can close our eyes and do as if these things did not exist. Just for a few days....
