Question

Which describes the relationship between the concentrations of atmospheric carbon dioxide and average global temperatures over time

Answer 1

There is a positive correlation between the concentrations of atmospheric carbon dioxide and average global temperatures over time. As carbon dioxide levels have risen due to human activities such as burning fossil fuels and deforestation, the Earth's temperature has also increased. This is known as the greenhouse effect, where carbon dioxide acts as a trap for heat radiating from the Earth's surface, leading to global warming.
