The claim that greenhouse gases warm up the Earth by 33°C
refers a joint statement by national academies of Brazil, Canada, China,
France, Germany, India, Italy, Japan, Russia, UK and USA in 2005: “the
existence of greenhouse gases in the atmosphere is vital to life on Earth – in
their absence average temperatures would be about 30 centigrade degrees lower
than they are today.” This claim has
been widely endorsed since by numerous academic institutions including the IPCC
around the world.
However, this claim turns out false; it is simply a result
of misuse of the Stefan-Boltzmann law by climate scientists. When deriving this conclusion, climate
scientists made technical errors:
1)
treating
the Earth as a blackbody while it never is;
2)
using wrong temperature quantity that is not the
temperature quantity defined by the physics essence of the Stefan-Boltzmann
law;
3)
classifying temperatures raised by greenhouse
gases as a different physical quantity outside the Stefan-Boltzmann as well as other related physics laws.
