In an article from the Herald Scotland, Fresh Evidence Global Warming Is Man-Made, absolutely no evidence is provided to support the hyperbolic headline. Nor is the alleged "review" article cited, so we can't go see for ourselves this astounding evidence of an impending man-made catastrophe.
As it turns out, there is no evidence, no fingerprint, no smoking gun.
There are, however, computer models that have been molded, tweaked, fiddled with and poked about until, if this bit of media fluff is to be believed, they bear some vague resemblance to external climate reality.
And yet, even if the model does parallel some observations (not all observations), it's still only an interpretation on the part of the UK Met Office that this comprises a "fingerprint" of human influence.
When one has only a hammer for a tool, everything resembles a nail.
