All Scientists are Sceptics ~Professor Bob Carter

“Climate is and always has been variable. The only constant about climate is change; it changes continually.” ~Professor Tim Patterson

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

Peer-reviewed: man-made CO2 is not the driver of global warming

Ole Humlum, Professor of Geosciences at the University of Oslo has an important new paper published in Global and Planetary Change which finds that changes in CO2 follow rather than lead global air surface temperature and that "CO2 released from use of fossil fuels have little influence on the observed changes in the amount of atmospheric CO2

Dr. Humlum summarizes the main findings of his paper:
  • [Observations show] The temperature rise begins at sea level and spreads gradually to the land and atmosphere several months later. This is contrary to the IPCC CO2 hypothesis that atmospheric CO2 controls land and ocean temperature.
  • The geographical distribution of a CO2 increase doesn't start at 30-50 degrees North latitude, which one would expect if the source were mainly created by the fossil fuel industry and transport in the Northern Hemisphere.  Instead, the increase of CO2 starts just south of the equator. This is contrary to the IPCC hypothesis that use of fossil fuels is the primary cause of increased CO2 levels.
Dr. Humlum notes that existing climate models are based on the improper assumption that CO2 controls temperature and have not provided skillful predictions so far

The highlights of the paper are:
  • The overall global temperature change sequence of events appears to be from 1) the ocean surface to 2) the land surface to 3) the lower troposphere. 
  • Changes in global atmospheric CO2 are lagging about 11–12 months behind changes in global sea surface temperature. 
  • Changes in global atmospheric CO2 are lagging 9.5-10 months behind changes in global air surface temperature. 
  • Changes in global atmospheric CO2 are lagging about 9 months behind changes in global lower troposphere temperature. 
  • Changes in ocean temperatures appear to explain a substantial part of the observed changes in atmospheric CO2 since January 1980. 
  • CO2 released from use of fossil fuels have little influence on the observed changes in the amount of atmospheric CO2, and changes in atmospheric CO2 are not tracking changes in human emissions.

    1. just received an email that I was asked for here,

      what's up doc ? It takes two long here to get comments up, come on over to uknowispeaksense and you can ask questions in real time unopposed.
