Therefore, the power absorbed/incident to the Earth is equal to, where $S$ is the solar constant: $$P_\text{in}=(1-\alpha)\frac{S}{4}A$$ -Greenhouse gases are responsible for remaining increases in temperature. +Greenhouse gases are responsible for remaining increases in temperature. By absorbing and then re-emittng their natural frequencies of electromagnetic radiation (infrared for greenhouse gases), they delay the release of radiation back into space and heat up the atmosphere. ## Resources
