Top Climate Scientist: CO2 Model Assumptions “Invalid”
Concerning global sea level rise, Professor Ole Humlum believes the planet will see only “8-15 cm rise by the year 2100”. And though most scientists agree man is warming the planet through CO2 emissions by burning fossil fuels, Prof. Humlum wrote that the figure for CO2 climate sensitivity is completely in dispute.
Natural factors at play, modest cooling ahead
On what has driven the climate change observed over the past 40 years, Prof. Humlum wrote that it goes far beyond just CO2 and that the sun, clouds and oceans have played huge roles. Over the coming decades he thinks the planet will cool, but that “it won’t be dramatic”.
Concerning whether the 20th century warming has led to more weather extremes today, he answered: “No, not according to statistics known by me.”
“Natural climatic variations dominate”
He summarized:
On the global scale natural climatic variations dominate over effects caused by man. Climate models often claim to incorporate natural variations, but this is not correct, as can be shown by statistical analyses. Thus, the argument that only by assuming a large effect of CO2 can climate models reproduce global climate change since 1950 is invalid.”
Bringing expertise to climate science
Prof. Humlum has authored or co-authored some 100 publications on climate related topics. Few scientists are able to claim having such a broad and valuable interdisciplinary knowledge that Professor Humlum possesses. His specialties include:
- Glacial- and periglacial geomorphology
- Landforms derived from bedrock weathering, with emphasis on rock glaciers
- Reconstruction of Quaternary ice sheets, glaciers in the North Atlantic region
- Historical and modern climatology of the Arctic and North Atlantic region
- The impact of climate on societies the North Atlantic region
- Comparison and integration of different climate proxy series
- Numerical modelling in geomorphology
- Mapping Arctic and Antarctic surface temperature changes
- Modelling natural cold-climate geomorphic processes and -hazards
- Permafrost and periglacial processes
- Physical geography of Svalbard
- Snow avalanche risk in Svalbard

“CO2 Model Assumptions “Invalid”
Of course it’s invalid, for it to be valid we would have to measure the CO2 heating atmospheric water (through high frequency IR translation to lower frequency IR) in the lower troposphere, we would also have to find a upper troposphere tropical hot-spot. Measurements on such observations have found next to nothing.
Next step is to show that meager photon energy assumed by cAGW advocates to warm the atmosphere through CO2 re-radiation (at low frequency IR) is mostly dissipated by molecular collisions.
That is to say that the few excited CO2 molecules do not re-radiate IR energy.
