As a result, when the Earth is closer to the Sun (and the Sun is high in the southern hemisphere’s sky), the southern oceans scatter more light and heat directly back into space than occurs when the Sun is higher over the northern hemisphere during the other half of the year. Had the extra energy sent back into space when we are closer to the Sun been absorbed by our planet, the Earth would, indeed, heat more during this time than when the Sun is over the northern hemisphere.
