Changes in clouds and the ozone layer reveal human impacts on the atmosphere


Human activity has a significant impact on the Earth’s atmosphere. The disastrous consequences of changes to the atmosphere have been widely researched regarding carbon emissions, but changing cloud formation and holes in the ozone layer play significant roles as well. Clouds are responsible for simultaneously reflecting the sun’s heat and trapping it in the atmosphere. The ozone serves as a protective layer in absorbing ultraviolet radiation from the sun. It is predicted that as climate change progresses, clouds will diminish in frequency, allowing more solar energy to reach the Earth.

Human-Induced Pollution Reaches New Heights With Space Debris

On Sept. 23, 2020, Jim Bridenstine, head of NASA, tweeted, “Debris is getting worse!” referring to floating junk particles in space, a majority of which lie in the lower Earth orbit. His tweet also mentioned that, throughout 2020, the International Space Station was maneuvered thrice to avoid any collision with the debris moving 18,000 miles per hour.
