What has happened the carbon dioxide in the atmosphere since 1958?

Since 1958, atmospheric carbon dioxide (CO2) levels have significantly increased, primarily due to human activities such as fossil fuel combustion, deforestation, and industrial processes. The Mauna Loa Observatory began measuring CO2 in 1958, recording levels around 315 parts per million (ppm) at that time. As of 2023, CO2 levels have surpassed 420 ppm, marking a rise of over 30% in concentration. This increase is a major driver of climate change, contributing to global warming and associated environmental impacts.
