Global CO2 now at 424.55 parts per million (ppm), according to Mauna Loa Observatory, Hawaii (NOAA).

It went up 4ppm the past year, compared with 1ppm the year before.

Past three years of methane increase have been unprecedented. Methane is a far stronger greenhouse gas than CO2. Figures from NOAA, I stitched the table together.
