This
is from Roger Caldwell an American scientist in the Philipines
concerned with climate change. It's not good news.
"Last
year, 2015, saw the largest rise in global CO2 concentration since
records began. The rise was 2.99ppm. This year, that record will
again get smashed, as were already 3.58ppm higher than 2015.
This
is happening even though mankind emissions have stayed flat for the
last 3 years (according to the IEA) due largely to phenomenal growth
of RE (wind and solar).
This
is really bad news because it means that nature, not man, is now in
control of the extinction event that we started.
The
record El NiƱo can be credited for part of the rise, for example,
the combined years of '97/'98 saw an increase of 4.78ppm. But it
doesn't compare to the 6.57ppm were seeing thus far in '15/'16.
We've
crossed the tipping point. CO2 is now rising faster due to climate
feedback than it is to mans emissions. In other words, we're fucked."
The increase in carbon
dioxide level
The
graph shows recent monthly mean carbon dioxide globally averaged over
marine surface sites. The
Global Monitoring Division of NOAA/Earth System Research Laboratory
has measured carbon dioxide and other greenhouse gases for several
decades at a globally distributed network of air sampling
sites [Conway,
1994].
A global average is constructed by first fitting a smoothed curve as
a function of time to each site, and then the smoothed value for each
site is plotted as a function of latitude for 48 equal time steps per
year. A global average is calculated from the latitude plot at each
time step [Masarie,
1995].
Go here for
more details on how global means are calculated.
The
last four complete years plus the current year are shown here. The
last year of data are still preliminary, pending
recalibrations of reference gases and other quality control checks.
Data
are reported as a dry air mole fraction defined as the number of
molecules of carbon dioxide divided by the number of all molecules in
air, including CO2 itself, after water vapor has been removed.
The mole fraction is expressed as parts per million (ppm). Example:
0.000400 is expressed as 400 ppm.
The
dashed red line with diamond symbols represents the monthly
mean values, centered on the middle of each month. Theblack
line with the square symbols represents the same, after
correction for the average seasonal cycle.
The
latter is determined as a moving average of SEVEN adjacent seasonal
cycles centered on the month to be corrected, except for the first
and last THREE and one-half years of the record, where the seasonal
cycle has been averaged over the first and last SEVEN years,
respectively.

I think we passed the tipping point in 2012.
