Would humans habituate to Carbon dioxide over the years,,.¿
Answers
Answer:
Life on Earth has evolved under these conditions - note that humans did not appear until about 200,000 years ago - and atmospheric CO2 has not exceed that concentration until the industrial revolution brought with it massive emissions from the combustion of fossil fuels: coal and oil.
Explanation:
The simplified global carbon cycle; carbon reservoirs (GtC) represented within the boxes and associated fluxes (GtCyr−1) indicated by solid arrows between the reservoirs. The broken lines represent long-term (millennia) movement of carbon within the system. A simplified summary of the global carbon budget is also given. Values are for the 1990s. The most important natural fluxes in terms of the atmospheric CO2 balance are the land-atmosphere exchange (+1.4 GtCyr−1), which includes land-use change and in enhanced vegetation growth, and the physical ocean-atmosphere exchange (+1.7 GtCyr−1). Fossil fuel burning (−6.3 GtCyr−1) represents the largest anthropogenic release of CO2 to the atmosphere. The net result of these processes is an increase in atmospheric CO2 concentration of +3.2 GtCyr−1. From Broadmeadow and Matthews (2003).
