This chart comes from NOAA (National Oceanic and Atmospheric Administration). The bottom scale is the last 400,000 years on earth. The left side scale and bottom line show atmospheric CO2. The right side scale and top line show Celsius temperature.
Earth’s climate has definitely been changing. Too bad the IPCC (Inter-government Panel on Climate Change) is only focusing on man made CO2. Our so called “global warming” trend appears to be a re-occurring 100,000 year cycle. Normal earth weather appears to be much colder—75%—of the time. Oops!
- Video below talks about the most recent 400,000 years of climate change on earth. It comes from the Thunderbolts Project web site.
