Which provides evidence that humans are causing an increase in the net movement of carbon dioxide concentration into the atmosphere
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.
