1998 ClimateGate email: "The problem of different Markers having different 1990 emissions values (and the fact that 1990s C emissions diverge from those observed) is more serious"

ClimateGate email

“very laudable scientifically, but it presents policymakers (for
whome the whole IPCC exercise is undertaken) with a problem.”

“The problem of different Markers having different 1990 emissions values
(and the fact that 1990s C emissions diverge from those observed) is more
serious.”

“Surely we need to impose a 'fix' on all 4 Markers to account for this.”

“CH4 1990 emissions range from 281 to 481Tg ... Surely this range is not defendable.”
