    Are you sure about that? I’ve read that that the main source of heat / temperature on earth is Sun. CO2 is produced mainly by oceans and it is a derivative of temp. Human activity is responsible for maybe less than a 1% of all CO2 emissions. And this was proven years ago. Also - on the scale from my link a million years is like maybe a pixel, so are you sure there were no short periods (50-100 years) when temperature changed rapidly?

      Are you serious? I’m not sure you’re arguing in good faith.

      Yes the energy, comes from the sun. More of it stays in the atmosphere because of CO2, making it warmer.

      Yes, human CO2 emissions only make up a small percentage of total CO2 emissions. Nobody is denying that. But the natural emissions are part of a cycle that is stable. They get reabsorbed.
      The relatively tiny amount humans added to the atmosphere (about 100 ppm since the start of industrialization) still has a huge effect.
