Global warming isn't a hoax. Paleogeologists have proven that if there is such a thing as a temperature the earth is "supposed to be" it is about 7 degrees warmer than today. We have dipped below that many times including this period we are in. For a period after life appeared on the earth it was 12 degrees warmer than today.
Present day and/or anthropogenic caused global warming is a hoax.
