would have been >500 ppmv (parts per million by volume) rather than 280 ppmv (Maier-Reimer et al., 1996). The horizontal distribution of CO2 and ΣCO2 in the surface ocean is mainly governed by the temperature-dependent solubility of CO2 on interannual timescales. Warm low-latitude surface water generally holds less CO2 (~10 µmol kg−1) and

Today's CO2 concentration has not been exceeded during the past Jan 26, 2017 observatory in Hawaii, the CO2 level stood at 316 parts per million (ppm), just a little higher than the pre-industrial level of 280 ppm. 400 was With CO2 concentration oscillating between 180 and 280 ppmv during the last 4 climatic cycles. In a similar way the methane concentration followed closely The options are to use the spatially varying CO2 passed from the atmosphere to the land, termed BGC, or to use 280 ppmv. Using BGC essentially allows 280 ppmv.
2 concentration has increased by more than 45% since the start of the Industrial Revolution, from 280 ppm during the 10,000 years up to the mid-18th century to 420 ppm as of April 2021. The present concentration is the highest for 14 million years.
ppmV).
280 ppmv in the late middle Miocene . A stable paleo-[CO 2] atm curve with slight changes around 210 ppmv from the MCO to late Miocene was drawn based on phytoplankton δ 13 C alkene analysis [49,50]. When the concentration of CO 2 is doubled, convective velocities increase. On the left is the histogram of velocities in the 280-ppmv case.
