The fact that both the troposphere and stratosphere show warming trends would best support the argument that Earth's atmosphere is warming as a result of an increase in solar output rather than increased concentrations of greenhouse gases because greenhouse gases tend to have a greater impact on the lower troposphere, while increased solar output affects both the troposphere and stratosphere.
