2013-12-03 · Recent estimates suggest CO 2 levels reached as much as 415 parts per million (ppm) during the Pliocene. With that came global average temperatures that eventually reached 3 or 4 degrees C (5.4-7.2 degrees F) higher than today’s and as much as 10 degrees C (18 degrees F) warmer at the poles.

An indoor CO2 level of 1 150 ppm provides adequate air quality, 1 400 ppm will ensure good indoor air quality in most situations, and 1 600 ppm indicates poor

This is because the natural rate of decline is less than the current rate of human-caused increases. 400 PPM CO2 in Words. Beyond 400 PPM CO2 2020-11-16 · The CO2 limit was removed from Standard 62.1 based on the confusion that it caused and the fact that it is not a good indicator of ventilation or IAQ. Many papers, presentations and workshops have attempted to clarify the meaning of indoor CO2 concentrations and advocated that they not be used as IAQ or ventilation metrics.

Do you know such a # for a P_CO2 of 400 ppm = 0 .000400 atm. # Calcite 0 A child born today will barely have moved out of Mom's basement (at least, judging by some millennials) by the time CO 2 reaches 500 ppm. The hundred-point rise between 300 to 400 ppm took about a century; the rise between 400 to 500 ppm will take only about 35 years, and with accelerating rates, the rise to 600 ppm will happen even faster.
