An increase in atmospheric oxygen levels could heighten the risk of fires, potentially affect respiratory systems due to increased oxidative stress, disrupt ecosystems by favoring certain species, and impact ozone distribution in the atmosphere. However, such significant changes in oxygen levels are unlikely to occur naturally over a short period. The Earth's current atmospheric balance has developed over millions of years and is relatively stable.
If the level of oxygen in the atmosphere increases, the atmosphere will thicken and scatter more sunlight. This will cause the sky to appear bluer and the air temperature to decrease.
The atmosphere will also scatter most of the sunlight that reaches the Earth's surface, resulting in less vaporization and less production of water vapors. This will also cause a decrease in temperature.
