Why does oxygen have stronger attractive forces between its nucleus and valence electrons than nitrogen?

The higher the amount of protons, the higher the amount of attraction, and the higher the attraction, the higher the electronegativity. N has 7, and O has 8. Therefore Oxygen has a higher level of electronegativity

When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down. A small part of the correspondence is due to the relationship between temperature and the solubility of carbon dioxide in the surface ocean, but the majority of the correspondence is consistent with a feedback between carbon dioxide and climate.
