Detailed explanation-1: -Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

Detailed explanation-2: -Most Americans recognize climate change, but some are still unsure about its causes. Tens of thousands of scientists in more than a hundred nations have amassed an overwhelming amount of evidence pointing to a clear conclusion: Humans are the main cause of climate change.
