What Relationship Has Been Shown by the Data from Antarctic

Question

What relationship has been shown by the data from Antarctic ice cores?
A) a positive correlation between carbon dioxide concentration and ice core temperature
B) a negative correlation between carbon dioxide concentration and ice core temperature
C) no correlation between carbon dioxide concentration and ice core temperature
D) a confusing relationship between carbon dioxide concentration and ice core temperature

Accepted Answer

Antarctic ice cores have shown a positive correlation between carbon dioxide concentration and ice core temperature, indicating that periods with higher CO2 levels are associated with warmer temperatures. This relationship is a key piece of evidence for understanding historical climate changes and the role of greenhouse gases in influencing Earth's climate.
