Front

Why do carbon dioxide concentrations and surface temperatures show the relationship seen in the graph from 1880 to 2000? Options: because lower carbon dioxide levels mean more heat is retained in Earth's atmosphere, because higher carbon dioxide levels mean more heat is retained in Earth's atmosphere, because lower carbon dioxide levels mean less heat is retained in Earth's atmosphere, because higher carbon dioxide levels mean less heat is retained in Earth's atmosphere

Back

because higher carbon dioxide levels mean more heat is retained in Earth's atmosphere

Front

What is climate change?

Back

a long-term change in the earth's climate, especially a change due to the increase in the average atmospheric temperature.
