The increased levels of CO2 in the atmosphere are causing sunlight to be trapped, leading to a warming effect known as the greenhouse effect. This can result in changes to the Earth's climate and weather patterns.
The meteorite collision at the end of the Mesozoic era led to widespread fires, dust, and debris in the atmosphere, resulting in a significant temperature drop and altered sunlight reaching the Earth's surface. This caused a mass extinction event, including the extinction of the dinosaurs and about 75% of all species, leading to significant changes in the Earth's biosphere and ecosystem dynamics.
During the Precambrian time, the Earth's atmosphere underwent significant changes, transitioning from a reducing atmosphere dominated by gases like methane and ammonia to an oxidizing atmosphere with increasing levels of oxygen, due to the development of photosynthetic organisms. This increase in oxygen levels laid the foundation for the evolution of complex multicellular life forms.
Oxygen levels have decreased slightly due to human activities, while carbon dioxide levels have increased significantly due to the burning of fossil fuels. Other gases, like methane and nitrous oxide, have also increased due to agricultural and industrial activities.
The burning of fossil fuels such as coal, oil, and natural gas for energy production releases CO2 into the atmosphere. This process is a significant contributor to the increased levels of CO2 in the atmosphere and is a major driver of climate change.
Global temperatures have increased as atmospheric levels of carbon dioxide have risen, due to the greenhouse effect trapping heat in the atmosphere. This phenomenon is known as global warming, leading to climate change and resulting in more frequent and severe weather events.

Early photosynthetic bacteria, such as cyanobacteria, were responsible for changing the formerly poisonous atmosphere to an oxygen-rich atmosphere through the process of photosynthesis. These organisms released oxygen as a byproduct of converting sunlight into energy, which gradually increased the atmospheric oxygen levels over time.

No, in fact, the opposite will happen. Increased carbon dioxide (CO2) levels in the atmosphere are producing an enhanced (or accelerated) greenhouse effect which is causing global warming.
Increased levels of greenhouse gases in the atmosphere are causing global warming.
The burning of fossil fuels is the largest contributor to increased levels of CO2 in the atmosphere. This includes activities such as driving cars, generating electricity, and industrial processes, which release CO2 as a byproduct.
