Why is the sun brighter than usual?

Answer 1

The Sun may seem brighter than usual as the Earth's ozone layer has degraded ~80% since the mid 1970's due to the prodution and use of fossil fuels. The Ozone layer is the part of the atmosphere which absorbs the vast majority of solar radiation, and thus a detriment of 80% of it's original composition will impose an inverse effect on it's ability to absorb the sun's radiation. Human beings, and all of the 30 million species on the planet were evolutiuonarily designed for an ozone layer about 5 times the strength ours is now, as we evolved prior to the environmental stresses indirectly imposed by over use of fossil fuels. This can be characterized medically by the increase in melanoma and skin-diseases since 1974 (Initial melanoma incidence 1/1800 in 1970, melanoma incidence 1/50 nowadays, 1/20 by 2025). We can use sunscreen to mitigate the risk of getting these diseases, though the other 30 million species on the planet, which are typically outside and exposed to the sun, will likely die off or mutate in time and will thus offset the ecosphere mechanics to an endgame state, such that our pedestal at the top of the chain will not be so supported.

The tradeoff of the use of fossil fuel benefits (cheap transportation, heating, air conditioning) happens to offset the entire sustainability of the earth's ecology, a very sad thing. On the other hand, air conditioners are very pleasant on a hot day.

Answer 2

The sun may seem brighter than usual due to a combination of factors such as atmospheric conditions, the angle of sunlight, and potentially reflective surfaces like snow or water. It can also appear brighter during certain times of the day, like sunrise or sunset, when the sunlight has to pass through more of the Earth's atmosphere.
