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 cause rising global temperatures, understanding how greenhouse gases (like CO2) affect earth's temperatures is key. Knowing pre - human global temperatures, human activities adding CO2, or CO2 levels before 1750 doesn't directly link CO2 to temperature rise as directly as understanding the greenhouse gas - temperature relationship.

Answer:

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