This is all you need to know: When temperatures on Earth went up... so did the temperatures on Mars and Venus. Pretty sure there’s no carbon-spewing SUVs on those planets.
The Sun is a giant fusion furnace that heats planets at several-light-hours’ distance. When its output fluctuates, everything in the solar system is affected.
“When its output fluctuates, everything in the solar system is affected.”
Well, that’s not fair. We need to organize for solar justice.
It’s amazing, really, how the sun affects everything about our planet....no wonder God set it there... and it does “RULE the day.”
The sun's magnetic field affects the Earth's. The sun's eleven year primary sunspot cycle is a symptom of the sun's fluctuating magnetic field. The Earth's field is alternately compressed and expanded by the sun's magnetic field cycle, and more or less cosmic rays rain in and cause cloud formation at different rates and altitudes. Water vapor is orders of magnitude more significant than CO2 as a "greenhouse" gas, hence Earth goes through cycles of warming and cooling coupled to the sunspot cycle.
It is not possible to determine how CO2 affects climate until an accurate model incorporating the naturally driven fluctuations of water vapor in the atmosphere are constructed and validated. I understand that the current climate models typically ignore this difficult problem.
