Carbon Dioxide –  – is a harmless trace essential gas in the atmosphere that humans exhale from their mouth (after inhaling oxygen). […] Carbon dioxide fertilizes algae, trees, and crops to provide food for humans and animals. We inhale oxygen and exhale . Slightly higher atmospheric  levels cannot possibly supplant the numerous complex and inter-connected forces that have always determined Earth’s climate. So-called ‘hottest year’ claims are just a fancy way of saying that the ‘global warming pause’ has essentially continued. Arctic ice changes are not ‘proof’ of manmade global warming, nor are they unprecedented, unusual, or cause for alarm, according to experts and multiple peer-reviewed studies. Sea levels have been rising since the last ice age ended more than 10,000 years ago. There is currently no acceleration in sea level rise.   Dr. Mann was at the center of the Climategate scandal. His graph and the data and methodology behind it have been scrutinized and debunked in peer-reviewed studies by numerous climate scientists, statisticians, and other experts. Many in the media repeatedly cite the various Climategate investigations as an ‘exoneration’ of the  global warming scientists. But a closer look reveals that the investigations were nothing more than the global warming industry pretending to investigate itself, and of course finding no wrongdoing. The reality is that politicians who say government ‘can do something about droughts, floods, sea levels, hurricanes, and tornadoes are practicing the equivalent of medieval witchcraft.
