Man-made carbon emissions increase atmospheric CO2

The man-made carbon emissions have caused the recent increase in atmospheric CO2 concentration.

This post sums up in english the posts dated 10 June, 9 May and 28 January 2013.

This blog post refutes the article The phase relation between atmospheric carbon dioxide and global temperature [1] recently published by Ole Humlum, Kjell Stordahl and Jan-Erik Solheim (Humlum et al). They claim that there is no correlation between the man-made (anthropogenic) carbon emissions and atmospheric CO2 concentration. They more than suggest that the CO2 increase is caused by rising global temperatures. Their cause-effect explanation is opposite to the consensus among climate scientists, which is that the increased concentration of CO2 is man-made and that it has caused the increase in global temperature.

Mark Richardson [2] and Troy Masters / Rasmus Benestad [3] have published Comments to Humlum et al's article in which they show that the article contains serious errors. This blog post will do the same.
