Willis Eschenbach has written a comprehensive article on adjustments to temperature in Darwin, some increasing the rate of warming by as much as 5C/century. Thanks to readers I have the daily temperatures from the Torok and Nicholls network, and plotted their minimum, maximum and mean temperatures for Darwin. The rates of warming are 1.3C/century and 1.4C/century for the min and max respectively. Moreover, the T&N adjustments are too small to distinguish.
I must admit I don’t understand what’s going on with all of these datasets, and why they need all these adjustments. Willis has a theory.
Now, I want to be clear here. The blatantly bogus GHCN adjustment for this one station does NOT mean that the earth is not warming. It also does NOT mean that the three records (CRU, GISS, and GHCN) are generally wrong either. This may be an isolated incident, we donâ€™t know. But every time the data gets revised and homogenized, the trends keep increasing. Now GISS does their own adjustments. However, as they keep telling us, they get the same answer as GHCN gets â€¦ which makes their numbers suspicious as well.
And CRU? Who knows what they use? Weâ€™re still waiting on that one, no data yet â€¦
