I have been watching the curve for several years.  Because of the seasonal variation it only makes sense to compare dates from the same time of year.  For this reason I publish a comparison to what the CO2 level is for the current month (actually last month) against the matching month one year ago at:

KDog's excellent adventure.

Today I published July:

Atmospheric CO2

July 2023      422.14 ppm
July 2022      418.85 ppm
Annual change:      +0.79%

The important thing is what the automatic percentage calculation yields.  Last month showed an annual increase that is huge.

Annual change:      +0.79%

Kinda close to a one percent increase in only 1 year.  Doom is served.  Green plants are not sucking CO2 as hard as they were last year.  Could it be because it is getting too warm for verdant growth?  I hope not!

The problem is CO2 concentration limits plant growth.  More CO2 means more plant growth, because there is ample sunlight to support faster growth.  CO2 is the normal limit.  Water is also needed for verdant plant growth.  Higher temps could dry plants out.

Higher summer temps could also raise plant metabolism causing plants to respire and release CO2 trapped earlier in the day.

The highest year to year variation I have seen is from last months' data.  This is not good.
