Final answer:

Carbon dioxide, a primary greenhouse gas from human activities, is the most widespread and long-lasting in the air, influencing global climate dynamics.


Explanation:

Carbon dioxide is the greenhouse gas emitted by human activities that is the most widespread and remains in the air the longest. It is a primary greenhouse gas contributing to recent global climate change, mainly released by burning fossil fuels and changes in land use.

Methane, another greenhouse gas, is also emitted by human activities and has significant potency in contributing to the natural greenhouse effect. However, carbon dioxide is considered more widespread and longer-lasting.

Human activities have a profound impact on increasing the concentration of carbon dioxide in the atmosphere, altering the Earth's climate dynamics and contributing to global warming.
