Which description best defines climate change?
Earth is getting hotter.
Earth's average atmopheric temperature is increasing due to additional greenhouse gases in the atmosphere and the enhanced greenhouse effect.

is confusing weather with climate
shouldn't be a senator talking about climate change if he doesn't know the difference between weather and climate
should take some more science classes so he can learn the difference between weather and climate
