Climate change was a hot topic during Thursday's GOP debate in Miami. During the debate, Florida Senator Marco Rubio declined to acknowledge the scientific reality of climate change and said, "One of the reasons the climate is changing is because the climate is always changing." Rubio isn't convinced it's a man-made problem. In response, Hillary Clinton tweeted out a GIF explaining it doesn't take scientist to figure out what's going on.
Rubio, whose answer you can see above, didn't just get a rebuttal from Clinton on Twitter. His GOP rival Ohio Governor John Kasich disagreed with him, too, saying he believes in climate change, as well as policies that are both good for the environment and economy. Watch Kasich's reponse below.
