Patience, dear boy, I don't spend all day fact-checking your latest anxiety about trams ...
Do they cause cancer? Will they somehow reduce Scotland's chances of winning the World Cup?
... or indeed wind turbines. Here's the best work I've seen, but it's a bit old. Short version, up to 100 times the then install capacity would be required before there's any chance of any identifiable effect, and even then it would lead to a "near-zero change in global mean temperature".
Furthermore, if we ever did make a change: "The direct climatic changes that are due to wind power may be beneficial because they can act to reduce, rather than increase, aggregate climate impacts."
Of course, what he meant to say was that he was now persuaded that running a train down the middle of the street is barking mad, but the wind turbine article is quite good and worth a read. It's a wee bit dense but readable enough.
While we're on climatic things, news reaches my delicate lugs that the estimable Alyn Smith MEP is in Copenhagen and he seems to have been making sure that people from all over the world know what Scotland's been up to.
Well done that chap!
