It matters because it changes how we would try to stop it. If it&#x27;s caused by something we&#x27;re doing, we could just change what we&#x27;re doing. If it&#x27;s natural, then we need to find a way to alter nature. That gets into terraforming, which we really don&#x27;t know how to do, and it&#x27;d probably be safer to to learn to live with the climate change rather than trying to stop it.
