4 sep. 2019 — Models now suggest we could get 1°C of additional warming from adding only 70 parts per million of CO2 to the atmosphere From ERS-CO2: 80 g. ERS-Sound: 70 g Noise: 14 ppm @ 400 ppm, 25 ppm @ 1000 ppm.
2021-2-5 · Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example: find how many percent are in 300ppm. x (%) = 300ppm / 10000 = 0.03%. ppm …
