Climate restoration

Today's CO2 is roughly 120 ppm higher than the highest levels humans have actually survived long-term. Nature has removed similar massive amounts of CO2 preceding ice ages, ten times in the last 800,000 years. The CO2 that reduces levels by 120 ppm is mostly converted to biocarbon by phytoplankton and stored in the deep ocean, and released when the ice-age ends. The phytoplankton growth corresponds with ocean iron concentration.[1]

Climate restoration is the climate change[2] goal and associated actions to restore CO2 to levels humans have actually survived long-term, below 300 ppm. This would restore the Earth system[3] generally to a safe state, for the well-being of future generations of humanity and nature. Actions include carbon dioxide removal from the Carbon dioxide in Earth's atmosphere, which, in combination with emissions reductions, would reduce the level of CO2 in the atmosphere and thereby reduce the global warming[4] produced by the greenhouse effect of an excess of CO2 over its pre-industrial level. Actions also include restoring pre-industrial atmospheric methane levels by accelerating natural methane oxidation.

Climate restoration enhances legacy climate goals (stabilizing Earth's climate) to include ensuring the survival of humanity by restoring CO2 to levels of the last 6000 years that allowed agriculture and civilization to develop.

(p1) ... there is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations. * * * (pp. 21–22) Some scientific conclusions or theories have been so thoroughly examined and tested, and supported by so many independent observations and results, that their likelihood of subsequently being found to be wrong is vanishingly small. Such conclusions and theories are then regarded as settled facts. This is the case for the conclusions that the Earth system is warming and that much of this global warming is very likely due to human activities.
