It's varied form 42C to 47C (daytime highs) here this month,
with dew points from -5C to 23C. A "dry heat" it's not, at
this time of year. :-(

When it gets to that in Skye, global warming won't be deniable by anybody.

You underestimate the abilities of some people to deny. Incidentally,

"Recorded history" dating back...200 years?

 The instrumental record does not go back that far in the sense of global coverage,  though isolated areas do have longer records - but there is then the question of accuracy, reliability, and so forth.
 We know the world is much warmer than in 1824 from a mass of data, but temperature records form a small part of this.
 In later times when we have more measurements, but still not global coverage, a lot can be done with statistical methods, but the fewer and worse distributed the observations, the larger the error bars.
 How far in the past we have a global temperature estimate accurate to within .2C is a question to which I don't have an answer.  I would suspect no less than 50 years or so, and possibly a hundred.
 The good news for me is that this summer I'm not coughing up bits of tree.  Of course, that is largely because so much of the susceptible area is still ash from last year.  But I'll take all the small victories I can get.

Where are you that you got smoked last year?  I live on the east side of the Sierra Nevada, where we had very bad smoke three or four years ago. This year we've been pretty good.
