I'm assuming that "physicalthe" is a typo, but I can't figure out how that sentence should read. Changing the sentence to "the IPCC has repealed the fundamental physical the Stefan-Boltzmann equation - that converts radiant energy to temperature." doesn't make any sense either.
Anybody care to venture a guess?
I'll give it a shot.
"the IPCC has repealed the fundamental physical the Stefan-Boltzmann equation - that converts radiant energy to temperature."
Just delete the word "the".
