Has it ever been this hot in Helsinki even once since the Big Bang?

Anthony Watts of WUWT is mocking Seth Borenstein for tweeting about "jet stream weirding", saying that it was a tad warm in Helsinki for 5 o'clock in the afternoon.  Anthony reckons it's nothing unusual.  WeatherUnderground says otherwise (it's a new record max for the date) and is on the side of Mr Borenstein.

But never mind that.  What I picked up was a classic response in the comments.  How often have you seen a fake skeptic write a response like the one below from Otter:

But seriously, do you guys think that the jet stream hasn’t been wonky for the last few years? Because the people who study it do.

Otter says:
June 26, 2013 at 9:53 am Ryan~ please demonstrate your proofs that such things have NEVER happened before in the history of this planet.

Otter's response epitomizes Anthony Watt's post beautifully.  If something has happened even once before in the 4 plus billion years of Earth's history, it's not only not a "record", it's not even extreme.
