Runaway Greenhouse Warming: Earth and Venus against Milky Way
Will Earth suffer runaway greenhouse warming like Venus. Pictures from NASA (PD).

Runaway greenhouse warming has been a concern of the Warming Alarmist for many years. They fear that Earth will become like Venus. And the fear is quite understandable, but also poorly founded. The following video shows why. Below the video are the sources for material used in the video as well as credits for media.

Runaway Greenhouse Warming: Graph estimating CO2 average for last 600 Myrs
To answer our question about runaway greenhouse warming, we need to understand the CO2 levels of the past. This graph helps us map out the average CO2 for the last 600 Myrs. Click on the graph to view it a little larger.

1,600 ppm average CO2 for last 600 Myrs
This is a rough estimate based on the work of R.A. Berner (2001), utilized on a CO2-temperature graph found at,
Because of the large uncertainty in the earlier proxy records, I erred on the conservative side.
The curve of CO2 on the graph yields an average of 2383 ppm. My conservative rough estimate was only about 2/3 of this.

4,000 ppm CO2 during Cretaceous Thermal Maximum

Cretaceous Thermal Maximum duration 6 Myrs

+20C global average temperature
Rough estimate from the amount of tropical warming stated at
[Note: In Al Gore’s film, he stated a fact that a global warming of 5 degrees would result in about 1 degree of tropical warming, but 12 degrees of polar warming. The UCSD article states that tropical warming was 5-7°C above today. If global climate were linear (and it’s not), then global average temperature would have been 25-35°C warmer than today, using Gore’s example. I welcome a more accurate estimate from this data.]

8,000 ppm Ordovician
This is a high-side estimate based on the graph at
This graph was also used earlier in estimating the average CO2 levels for the last 600 Myrs.

210,000 ppm Earth’s CO2
Actually, this is a minimum estimate. Very likely the CO2 level on Earth was much higher, because CO2 was sequestered by all manner of natural, chemical reactions in the Earth’s early history. Some estimate that Earth may have had as large a percentage of CO2 as does Venus now, but never that Earth had 91x today’s atmospheric pressure.
