The world started cooling 1995: conditions vary over the world, but the world weather correlates with predictable solar cycles, 1995+28=2023.
CO2 is irrelevant 0 global average CO2 is capped by photosynthesis on the land and seas. NOx is at 0.000000001%. as NOx is washed out of the air by natural; rain fall.
The dominant source of NOx is natural lightening – one bolt every 3 minutes around the Earth. The surface of a lightening bolt reaches 10milionoC.
1 H2O+TU->He2++02- lightening creates the potential difference, that at 5,000V, fires off a lightening bolt. Positive charge collects above the clouds, negative falls to the ground.
This is a big enough and constant energy system, there will be bacteria living above the clouds.
2 H2O+e-+TU->He2++O-+E2 E2=2.5x1030W per bolt.
Neither petrol or diesel cars is important enough a source of NOx, to be detectable.
NOx forms nitric and nitrous acids, which fertilizes natural plant growth. Which converts extra CO2 BACK into biomass within 5 minutes: in the Jurassic there was 65% more life on Earth – and 60 meters LOWER sea levels. At the mass extinction, that life went into the Fossil Fuels.
So as we burn the Fossil Fuels we are increasing lie on Earth. But CO2 is capped at 0.000002% by global photosynthesis. The oil countries went with Global Warming, as it riased oil prices. As the volume of oil shipped fell. It appears that yes, the world is that stupid.
Petrol cars produced as much NOx as diesel cars – which boosts natural plant growth. And is too low a trace gas, to even be measured. Any biology teacher will confirm this.
If we pass CH4 gas up a titanium honeycomb catalyst, we drip biodiesel down, we get biopetrol – a carbon 0 fuel: as it takes is the same CO2 to form as it releases when burnt.
We can form non fossil CH4, by passing CO2 and steam into a reactor vessel, at 350oC, at 1 atmosphere
3 CO2+3H2Os->CH4+He+4O2+O3 CO2 unburns!
So we do not need fossil natural gas. Any town or city can chill CO2 from the air. B oil water at super heat the steam using steam plasma tubes, and produce nearly free, and unlimited natural gas.
So neither petrol or diesel cars/engines need Fossil Fuels. Saudi Arabia just lost the oil trade. As steam plasma tube does H fission, the most potent energy source in the universe.
8 times as energetic as hyper toxic uranium nuclear fission. 1,600 times as energetic as a diesel flame.
