Just to confirm what
@Subduction Zone has mentioned. Yes, the solar rotation, sun spot cycles, the Milinković cycles, variance in atmospheric volcanic ash and CO2 from volcanoes, etc…etc… have ALL been included into the calculations. No. Those things are not it.
What concerns the scientific climatological groups is what
mankind has (and still is) adding ON TOP OF all of those well known natural fluctuations. What they are reporting on is the influence that man has had on climate. That is why it is referred to as
AGW (
Anthropological Global Warming).
“Hey, Dr. Williams. Did you factor in the reflective nature of water over 3/4 of the Earth’s surface?” “
D’OH!!”
Hey, Dr. Merrigold. Did you account for the temperature fluctuations between winter and summer?” “
Drat!!”
