Question

1. look at figures 2 and 3. a classmate argues that the rise in carbon dioxide (co2) levels in the atmosphere is causing the rising global temperatures. which of the following students questions, if answered, would provide information to help support this argument?

\how do greenhouse gases affect the earths temperatures?\
\what was the average global temperature before humans existed?\
\what types of human activities add to the amount of co2 in the atmosphere?\
\what did co2 levels look like before 1750?\

Explanation:

To support the argument that rising CO2 levels are causing rising global temperatures, understanding the impact of greenhouse gases (CO2 is a major one) on Earth's temperatures is crucial. The other questions are about past CO2 levels or human - related CO2 sources rather than the direct link between CO2 and temperature.

Answer:

"How do greenhouse gases affect the earth's temperatures?"
