Lucia Liljegren has discovered Kevin Trenberth being naughty with one of his graphs. I mean very naughty.
One can...speculate why Trenberth didn’t compare the 12 year flat (and negative) trend ending in 2012 to 12 year ‘flat’ trends in the past. The current period is the only period with a “flat” (or negative) trend. Presenting that comparison would certainly give “impression[.] that the global mean temperature is not increasing at its earlier rate”.
Oh dear. Read the whole thing.
