Today’s action by Pruitt is a wake-up call for those who continue to falsely claim carbon dioxide is a pollutant. It isn’t, so get over it! Carbon dioxide is a colorless, odorless, and tasteless gas that is essential for life on Earth. It will never cause the dangerous global warming that climate alarmists and their failed models predict. Future legal challenges to reverse Pruitt’s action are welcomed, as they will only fail in the end.
