Why do some scientists believe that carbon dioxide is responsible for global warming? check all that apply. carbon dioxide levels in the earth’s atmosphere have been steadily decreasing. carbon dioxide levels in the earth’s atmosphere have been steadily increasing. carbon has a longer average lifetime in the atmosphere. carbon has a shorter average lifetime in the atmosphere. other greenhouse gases amplify the effect of carbon dioxide.

Carbon dioxide levels in the Earth's atmosphere have been steadily increasing

Explanation:

Numerous scientists believe that the increase of the carbon dioxide in the atmosphere has been responsible for the global warming. This is debatable though, as there have been periods in the past of the Earth when the carbon dioxide levels have been higher than at present, but the climate has been cooler, and when the carbon dioxide levels have been lower but the climate has been warmer.

The global warming is in part connected to the amount of greenhouse gasses, such as the carbon dioxide, but there are also other major factors that dictate the global climate, factors known as the Milankovich cycles.

The panic among some scientists has mostly been because of the constant increase of carbon dioxide in the atmosphere because of the human activities. They believe that the higher concentrations of greenhouse gasses in the atmosphere will lead to an apocalyptic scenario on our planet, despite when looking at the geologic and paleoclimate data it seems that the Earth is actually a more pleasant place for living when there is global warming.
