Estimates for man-made global warming and need for global decarbonization The CO2-hoax could be easily unmasked with some roughly estimated numbers: 1. Since the beginning of temperature records in the 19th century the global mean temperature is said to have raised about 0,8 degree Celsius while the atmospheric CO2content has increased about 50%. If solely CO2 would affect the global temperature rise then a simplified linear approach for the logarithmic IPCC-function leads to (2 * 50% CO2 @ 2 * 0,8 °C with most atmospheric feedbacks from the past already included): ð Climate Sensitivity of CO2 @ 1,6 [°C/2xCO2] (exclusively from CO2, natural sources are neglected). You will find an IPCC-conform calculation here from page 9. 2. Furthermore, a “global CO2-budget” would be continuing renewable: The atmospheric CO2-content at 280ppm was about 3,000 Gigatons. Doubling the atmospheric CO2-content needs another 3,000 Gigatons while the lifespan of atmospheric CO2 is about 100 years. One receives then: ð An annual CO2-budget of 30 Gigatons/year (=3,000 Gigatons/100 years) is continuing renewable within the 1,5 degree IPCC-limit. You will find a detailed calculation at KalteSonne. Consequently, even if one should believe in Anthropogenic Global Warming, AGW. there is no rational reason for global decarbonisation… 1
