A new paper appearing in the journal Earth Sciences here authored by Hermann Harde of the Helmut-Schmidt-University, Hamburg Germany, is stirring up more controversy among the climate science community, which generally claims humans have been responsible for rise in atmospheric CO2 concentrations since the mid 19th century.
The opposite is true
According to Harde, it is not the added CO2 that is causing the global temperature to rise, but just opposite: “The temperature itself dominantly controls the CO2 increase. Therefore, not CO2 but primarily native impacts are responsible for any observed climate changes.”
Harde claims this is backed up by and “in agreement with all observations.”
The paper is expected to generate much opposition in a science whose claimed consensus has increasingly come under fire.
What follows below is the paper’s abstract:
The Intergovernmental Panel on Climate Change assumes that the inclining atmospheric CO2 concentration over recent years was almost exclusively determined by anthropogenic emissions, and this increase is made responsible for the rising temperature over the Industrial Era. Due to the far reaching consequences of this assertion, in this contribution we critically scrutinize different carbon cycle models and compare them with observations. We further contrast them with an alternative concept, which also includes temperature dependent natural emission and absorption with an uptake rate scaling proportional with the CO2 concentration. We show that this approach is in agreement with all observations, and under this premise not really human activities are responsible for the observed CO2 increase and the expected temperature rise in the atmosphere, but just opposite the temperature itself dominantly controls the CO2 increase. Therefore, not CO2 but primarily native impacts are responsible for any observed climate changes.”
The study builds on a previous controversial paper published in 2017: Scrutinizing the carbon cycle and CO2 residence time in the atmosphere in the journal Global and Planetary Change.
Hermann Harde is not alone in backing the hypothesis that temperature drives CO2, and not the other way around. Other scientists in Harde’s camp include, among others, Dr. Murry Salby. formerly of the Macquarie University in Sydney.
