«Very much the same results» isn't how I would describe a 0.1 K /
decade trend attribution to UHI [Jones et al. 2008] compared to 0.05 K / century [Jones et al. 1990].
Not exact matches
No
attribution is given, but the satellite data appears to be an early version of the UAH data series, with an apparent linear
trend of 0.04 °C per
decade.
My estimate is that between ~ 80 % to 120 % of the observed
trend in recent
decades is human - forced — i.e. which allows for 0.1 to 0.2 degC / dec either way for internal variability — natural forcings are a slight cooling factor on these timescales so that would imply a higher
attribution to human causes.
