So is global warming. We have known there is no rise in earth temperature for 15-years. Temperature is now dropping in some areas. Our scientists have publically admitted they invented the original data. Arctic ice mass has increased 1000s of square miles each year. This year the UN released a report that has everyone laughing, including themselves, and our Left continues to preach the gospel of global warming. Why? Global warming is big money and makes it necessary for governments to control the population in the name of saving the earth. Whenever you hear the government say, "We have to save you", run. Ronald Reagan said the worst thing you can hear is, “Hi! I’m from the government and I’m to help!”  ))) Whenever stating data, always good to cite the source. The evidence that "everyone knows this" is no evidence.  )))
