Plants and bacteria scavenge CO2 from the air, to turn into active life.
1 mCO2+(n+r)H2O->Cm(H2O)n+r(He+E2+L+X-ray) Cm(H2O)n is carbohydrates – the stuff of life
So plants exit a faint blue light, when illuminated by ultraviolet light – as they do Molecular Nuclear Fusion. All the Fossil Fuels were active life, mostly in the Cretaceous and Jurassic.
In the Jurassic there was 65% more active life on Earth, and sea levels 60m lower. So last year CO2 emission FELL by 6%: but again, free CO2 limited by plants and deep water bacteria doing photosynthesis to 2 parts per million.
So CO2 a STATIC TRACE gas. Which affects nothing. I sent this to Donald Trump, who is backing out of the Paris accord as you read this.
Another static gas is NOx (NO & NO2) which is washed out of the air by rain, to act as plant fertilizer. It facilitates life on Earth. No NOx, Earth is a lifeless lump of rock.
All this known to all 1st year high school pupils. But apparently not the man-made Climate Change pundits – in the pay of nuclear power.
