German Physicist: Human CO2 Emissions Responsible For 0.05°C Of The Global Warming Since 1750

Professor Herman Harde, an environmental physicist, has authored a new position paper on the follies of assuming humans significantly impact the climate.

As detailed in his 2017 paper, Dr. Harde concludes the “anthropogenic contribution to the actual CO2 concentration is found to be 4.3% [a figure derived from IPCC AR5], its fraction to the CO2 increase over the Industrial Era is 15% and the average residence time 4 years.”

The IPCC overestimates the thermal effect of doubling CO2 by a factor of 5, as the consequent surface air temperature increase for a 120 ppm increase in CO2 is less than 0.3°C.

“Since only about 15% of the global CO2 increase is of anthropogenic origin, just 15% of 0.3°C, i.e., less than 0.05°C remains, which can be attributed to humans in the overall balance.”

“Changes of our climate can be traced back to natural interaction processes that exceed our human influence by orders of magnitude.”
