Hi all,
According to our paper published January 2017, available for download
at: http://www.earth-syst-dynam.net/8/1/2017/ climate warming and ice
melt begins to deactivate the vertical cycling of ocean, even by
stratifying parts of it. Increasing temperatures and pH decrease at the
ocean surfaces, further deactivates their CO2 absorption capacity. Only
after the ice melt will have increased to much more massive levels
covering increasing ocean regions with melt water layers of lower
salinity the activation of phytoplankton assimilation by iron
fertilization originating from trapped mineral dust and glacial flour
may stop further greenhouse gas increase and climate warming. Should
mankind wait until these days when nature might be as friendly as to
stop any further climate warming in this way? No! Because nature has
shown us much more efficient tools how to stop climate warming and how
to turn climate temperatures back mankind should be able to stop climate
warming now by regulating the levels of the greenhouse gases by
depleting them just with those tools nature has presented to us many
times during the last million years.

Betreff: Re: [geo] Record Increase in Air CO2
I'd only add that in your way of thinking, the drain can also get
clogged (e.g., if the rate of ocean overturning is slowed by the
warming, which would also reduce the amount of nutrients coming to the
surface, so also slow the biological pump). This is how one would
presumably represent the increasing atmospheric fraction.

This is therefore a good time to educate people. Emissions did not
increase, but the annual rise in CO2 increased. It allows you to
explain that CO2, once put into the air, sticks to it.
I find it amazing that this far more intuitive way of thinking, has
been wiped out by a conceptually much more complex flow model, which
in this case is not even correct. I think you see 30 years of
education of acid rain misapplied to CO2. It seems much more
intuitive to consider a bathtub filling up in response to an open
faucet than to consider the faucet being in equilibrium with a drain,
and that the drain rate increases with increased fill, and that
therefore a particular filling rate from the faucet is associated with
a particular level in the tub. Note that having a drain is not
enough. If the drain rate is independent of the fill rate, raising the
flow rate from the faucet will lead to a continuous and unabated rise.
A sudden increase in the CO2 level in the atmosphere, will increase
the drain rate, but the drain rate slows down as the layer in
equilibrium gets thicker. One way of looking at it is to consider the
CO2 emission rate that holds CO2 in the air constant. It drops
rapidly over time, even if instantly it might be 50% of current
emissions.
Once this is understood, we can begin to worry why the fraction of CO2
that goes out of the atmosphere seems to shrink.

I'd guess what they meant was that global emissions were about the
same (I think the Global Carbon Project report has indicated this).
There is this serious misperception that if emissions don't go up,
concentrations won't go up, and so all we have to do is stop growth in
emissions.

Hi All
The Financial Times story was about reported emissions and the NOAA
report was about atmospheric measurements.
Perhaps reports have been tweeked or CO2 sinks have become less
effective.
