Atmospheric CO2 levels accelerate upwards

All the numbers we have heard about causes, haven't altered the overall increase in the PPM co2 number. I don't trust that we won't discover more about this situation. My hunch is flying is one of the biggest feedback mechanisms, because of where it happens (high in the atmosphere), how it interacts with the ecosystem (contrails), and the sheer volume of fuel used daily (economic vested interests).

I see contrails every day above my head, they fill the sky on some days.

There is a problem with the sky, the coincidence seems striking to me.

Like smokers in the 1930's being prescribed cigarettes - common sense should be able to indicate a truth that is yet to properly emerge.

This should be some interesting reading for you if you haven't read it already: Some scientists believe that from the days after 9/11 (when everybody was grounded) that planes and their pollutants actually have a cooling effect on the planet; they reflect sunlight more into space.

I did read that at the time, and it is interesting. But as James Lovelock says - one of the first people to alert us about rising co2 - smoke or soot is the only countermeasure we have now, but it is a very short term fix and the other gases mixed with it lead to rapid longer term warming.

Water vapour from planes (contrails) have a complex effect and is not yet fully understood see:
