Newton's law is for convection of heat into the air. The cooling of the earth happens by radiation into vacuum, so it's actually much MORE temperature-sensitive: the heat radiated is proportional to the fourth power of the temperature. https://en.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann_law https://en.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann_law
