the pre-industrial level of co2 on earth is 300 to 140ppm.
what is the pre-industrial level of co2 on earth?
300 to 140ppm
one of the principal goals for climate restoration is to bring the level down from current level of ~405 ppm (2016) towards its pre-industrial level of ~280 ppm. not only will this reduce ’s global warming effect but also its effect on ocean acidification. the removed carbon would be sequestered or used as construction material.

climate restoration
climate restoration consists of a goal and associated actions intended to reverse the current trends of climate change and, on some timescale and trajectory, to restore the earth system to a safe, sustainable and productive state, for the well-being of future generations and all humanity. such actions include the carbon dioxide removal from the carbon dioxide in earth's atmosphere, which, in combination with emissions reductions, can reduce the level of in the atmosphere and thereby reduce the global warming produced by the greenhouse effect of an excess of over its pre-industrial level. a main goal of the healthy climate alliance is the reduction of atmospheric to below 300 ppm (i.e. near its pre-industrial level) and refreezing the polar ice caps by 2050.
