You are just repeating the junk science you have read on the Internet. If you go back hundreds of thousands of years you will find great variations in the earth's temperature. We are nowhere near the warmest, nor the coldest. The biggest effect on the earth's temperature is...wait for it...wait for it...the sun.
For the rest of the questions at the end, you keep typing a lot of words that have little meaning.
Wrong - the biggest EFFECT upon climate CHANGE - is the amount of energy put into the atmosphere in TOTAL - such as various gasses released into the atmosphere - either due to volcanic/tectonic activity, biological activity, or our own activities - which are also taking energy from within the planet and putting it into the atmosphere - causing it to warm up.
The climate would not exist if not for the sun, no - but the changes in energy output of the sun that we know of, do not affect the climate to that degree purely by itself!
If the energy total of the entire climate system is A, the input from the sun B, and A>B, then the sun cannot be fully responsible! If the increase of A is greater than any changes in B, then the energy must be coming from somewhere else! The ONLY reason we've been ahving problems understanding what's going on, is because of the difficulty in measuring the entire energy contained within the system as a whole. The more accurate the reading, the greater the amount of A, and the greater of increase in A, over B.
Hence the amount of energy we're placing into the system by burning fuel that's been sealed underground for millennia...
The law of energy conservation is basic physics...
