The last time researchers believe the carbon dioxide concentration in the atmosphere reached 400 ppm — between 3 and 5 million years ago during the Pliocene — Earth was about 3.5 to 9 degrees Fahrenheit warmer (2 to 5 degrees Celsius) than it is today.
The general consensus among scientists is that the young Earth's atmosphere contained much larger quantities of greenhouse gases (such as carbon dioxide and / or ammonia) than are present today, which trapped enough heat to compensate for the lesser amount of solar energy reaching the planet.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
