Heathrow has always set the highest temperatures in the UK for obvious reasons. I grew up in rural England in the seventies and every kid who did so remembers, remembers the fifth of November because they were freezing their butts off watching fireworks, wrapped up in duffle coats and gloves. These days you can pretty much go out in a T shirt at that time of year. Must be all the planes at Heathrow.
I take it the Heathrow reference was a very lame attempt to reintroduce the completely discredited urban heat island effect. That was utterly disproved years ago.
The thing about arguing against science is that you don't actually have to prove anything. Hey, you don't even have to be consistent. The denial movement can say that manmade global warming isn't happening because the temperature records are being fabricated and then say that temperatures are going up because of sunspot activity and then it's underwater volcanoes and all these are equally valid arguments in the denial mindset although they contradict one another.
That doesn't really matter because all that matters is that they're against the predominant scientific evidence and they'll help to obfuscate the reality that 97% of the peer-reviewed science is telling us.
