The role of anthropogenic heat for global warming in the middle and far future is often underestimated. In the 4th IPCC report of 2007, it has been treated only casually, and in its 5th report of 2013/14 it was not mentioned at all. The latter holds also for commercial applications of nuclear fusion techniques that are driven by contrast on expensive international projects. Due to the anthropogenic heat production, these techniques are not sustainable - contrary to the claims of their advocates. Under those aspects, the online publication „Global Warming by Anthropogenic Heat Release“ of 2009 (URN: urn:nbn:de:gbv:ilm1-2009200065) has been updated and extended, again starting with the fundamental model calculations by Robert Döpel of 1973 (https://www.db-thueringen.de/receive/dbt_mods_00012380).
