Despite advances in renewable energy, most efficient appliances and vehicles, and saner lifestyles, carbon emissions grew 2% last year. Part of the reason is an unfortunate feedback system between energy use and climate change. As climate change produces greater swings in local weather, energy use increases to counter winter storms and summer heat waves. Climate change, which is partly created by pollution, induces more pollution which induces more climate change. Until we decrease carbon emissions, climate change will make our struggle more difficult.
