The history of major and minor climate changes, such as ice ages interspaced by warm periods, has been documented for thousands of years and evidenced by paleontological, geological and other research fields for millions of years. Abundant bibliography is easily accessible.
Very much, particularly industrialization and urbanization at the expense of forest has altered the carbon budget.
I'm sure that it changes the amplitude of the fluctuations, but does it change their course?
Did you have a look to the latest IPCC report?

It provides an extend view over all climate change scenerios and related expected impact.
Yes I did. But it doesn't go back for over 180 years (short term) and doesn't really discuss non-anthropogenic factors, E,g,, starting with abt. 1900 the sunspots activity is exceeding that of some recent centuries. Notwithstanding, "adaptation and mitigation" is necessary, because the pollution issued along with CO2 is killing thousands of people in industrialized areas.here and now. The projections?... well, presently we're unable to produce a reliable weather forecast for more than a week...
