A)the earth would undergo an uncontrollable greenhouse effect.
B)the earth would eventually reach a higher equilibrium temperature.
C)the amount of longwave energy radiated from Earth's surface would decrease.
D)the earth would have a surplus of incoming radiation energy compared to outgoing radiation energy until the Sun finally burned itself out.

If the Sun increased its radiative output, the Earth would eventually reach a higher equilibrium temperature. This is because more energy would be entering the Earth's atmosphere, and the Earth would need to radiate more energy back out into space to maintain a balance. Eventually, the Earth's temperature would increase to a new equilibrium point where outgoing radiation matches incoming radiation. However, this would take a long time and the increase in temperature could have significant impacts on the planet's climate and ecosystems.
