Large jump in this projection, as El Nino is just about to start,
returning to the value of Feb 2023, only matched by
July 2023 with July and Aug 2024.
For each of these graphical monthly outputs, I do a scale-matched blink
comparison for any changes in the earlier data.

For Mauna Loa data output 05 June 2025 at
https://gml.noaa.gov/webdata/ccgg/trends/co2_trend_mlo.png

and the earlier tabulated data

Using the off-line javascript curve-fitter at statpages.info
Of curve types , linear=no acceleration, exponential=increasing
acceleration, quadratic=fixed acceleration, indicial= falling
acceleration; indicial was best fit by R^2 factor again, but only very
marginally over the quadratic and exponential forms.

then adding yearly sine component,
y= a + b*x^c +  d*sin(e*x+f)*(1+g*x)

where x is year minus 2000 for data subset start year of 2003 to
avoid the decade of post-Pinatubo geodata recovery, 6
figures retained for anyone else repeating/checking this exercise (bear
in mind the graphical most recent data )
For June 2025 output
a= 371.262643
b= 1.070377
c= 1.219741
d= 3.001688
e= 6.264681
f= 6.411354
g= -0.001925
