Air conditioning. We can't live without it. And according to a new United Nations report, if we don't fix it, we won't be able to live with it, either.<br />Switching to energy-efficient and climate-friendly A/C units could save the world up to 460 billion tons of greenhouse gas emissions over the next 40 years.<br />While air conditioner producers aren’t using CFCs anymore, they’ve replaced them with industrial chemicals called hydrofluorocarbons, or HFCs.<br />According to Gizmodo, HFCs warm the planet up to 11,700 times more than carbon dioxide, making climate change much, much worse.<br />Higher temperatures force more people to turn to air conditioning, thus creating an unfortunate feedback loop.<br />If we deal with cooling wrong, we essentially cook ourselves.
