Ferdinand Engelbeen (@ 317): August 7th, 2011 at 1:51 am... Thus how then can we calculate the excess decay time?
For a linear model if you, say, increase all three CO2 isotope variants by 50 %, you could then measure what you call the «excess decay time» (what I meant by «residence time» as opposed to «exchange time») by watching the excess CO2 concentrations decay with time back to (or near to) the original amount.
Not exact matches
If we inject an excess amount of any one of the three isotopes, and measure the decay time of that isotope, we will measure the same decay time.
The Bomb Spike is just that «experiment» and the measurements of the excess C14 decay curve give us an 8 year half life for the atmosphere's recovery time from excess CO2.
FAQ 6.2, Figure 2 illustrates the decay of a large excess amount of CO2 (5000 PgC, or about 10 times the cumulative CO2 emitted so far since the beginning of the industrial Era) emitted into the atmosphere, and how it is redistributed among land and the ocean over time.
Decay of a CO2 excess amount of 5000 PgC emitted at time zero into the atmosphere, and its subsequent redistribution into land and ocean as a function of time, computed by coupled carbon - cycle climate models.
If there has been no actual increase in the CO2 as the historical data shows but that you and the climastologists ignore, then» the decay time of an excess amount of CO2 (whatever its source) in the atmosphere» has no meaning because there IS NO «EXCESS&excess amount of CO2 (whatever its source) in the atmosphere» has no meaning because there IS NO «EXCESS&EXCESS»
the decay time of an excess amount of CO2 (whatever its source) in the atmosphere» has no meaning because there IS NO «EXCESS&excess amount of CO2 (whatever its source) in the atmosphere» has no meaning because there IS NO «EXCESS&EXCESS»
The deep oceans take the rest of the 50 % of the sink rate, which all together gives a half life decay time for an excess amount of CO2 of about 40 years.
