This graph is denialist BS. First the current CO2 level is 420 PPM. Second the natural CO2 level is 280 PPM, not 384 PPM, so their "CO2 human" value is only off by 875%.

Humans have increased the CO2 content of the atmosphere by 50%. That increase has trapped the energy equivalent about 3.4 billion Hiroshima bombs, and is trapping the energy equivalent of more than 10 more every second.

Some of those bombs went off on the Gulf coast and in Appalachia. Ignore this at your own peril.
