1. Industrial activities: The burning of fossil fuels such as coal, oil, and natural gas releases large amounts of carbon dioxide into the atmosphere.
2. Deforestation: Clearing forests for agriculture, urban development, and other purposes reduces the number of trees that can absorb carbon dioxide from the atmosphere.
3. Increase in atmospheric carbon dioxide levels: Measurements of atmospheric carbon dioxide levels show a clear increase over the past century, coinciding with the rise of industrial activities.
Which provides evidence that humans are causing an increase in the net movement of carbon dioxide concentration into the atmosphere
