Can you point me to a post where I claimed the earths temperatures don't change naturally.
Please don't make up stuff just to suit your point of view.
Those cycles you refer to happen to coincide with increased CO2, so what do you think will happen if the natural cycle happens to coincide with man made contributions.
Well lets see, if increased Co2 in normal patterns leads to higher temperatures, then higher increases in CO2 will lead to higher temperatures.
Can we change the natural cycle to slow down the temp rise - No (well actually yes we could add sulphur dioxide See Mt Pinatubo)
