Question
Of the two sources of energy that power Earth, the Sun is the main driver of the planet's external processes. If the Sun increased its energy output by 10%, what would happen to global temperatures? What effect would this temperature change have on the percentage of water that exists as ice? What would be the impact on the position of the ocean shoreline? Speculate as to whether the change in temperature would produce an increase or a decrease in the amount of surface vegetation? How would the change in the amount of surface vegetation affect global temperature?
Explanation / Answer
As another scientist had pointed out a few years before, ultraviolet radiation from the explosive flares that accompany sunspots would heat the ozone layer high in the Earth's atmosphere, and that might somehow influence the circulation of the lower atmosphere.Greenhouse effect warming caused by human emissions of carbon dioxide gas ( CO2) would come on top of this rise, making for a dangerously abrupt warming.surface vegetation fully decrease.ice sheets will melts ,water level will increase.due to increased solar energy climatic conditions will change as warmer.
