I have also thought that but I do not understand why more attention is not
devoted to that what is happening is that the solar energy that was absorbed
into the system for many millions of years and stored as what is now fossil
fuels, has been largely used and that energy released within about 200
years, ultimately as heat. Thus it is not just the burning of fossil fuels
but the unbalance due to millions of years of accumulated solar energy being
released almost instantaneously. Why is that not talked about as a factor
that impacts on warming?

Frank,
While agree with your other points I can not let the first one go
unchallenged.
Burning the bush is only one step in a relatively short term cycle. As it
grows it sucks up carbon. When it is burnt, or dies and decays, the carbon
goes back into the atmosphere it came from. If the bush is burnt every X
number of years then on average nothing changes. (Note that I am only
referring here to the effect on atmospheric carbon dioxide levels, not the
ecology, which sadly is the loser in all this) The problem with climate
change is the burning of fossil fuels. They locked up the carbon millions of
years ago. Life as we now know it has evolved to be happy with the
concentration of carbon dioxide that remained in the atmosphere, until we
started adding to it by accessing and burning the fossil fuels.
