Maybe they forgot a keyword? It certainly isn&#x27;t the <i>sole</i> cause of global warming&#x2F;climate change, but it is real.<p>CO2 in the atmosphere--what&#x27;s historically known as the greenhouse effect--leads to earth&#x27;s warming. CO2 emissions are also undeniably connected to the the greenhouse effect, which we clearly have a role to play in. That&#x27;s science that no one disputes.<p>But somehow people come out of the woodwork as climate change denialists.<p>It doesn&#x27;t really make sense unless seen through a political lens, since politics is antithetical to science in a lot of ways.
