> Speaking of worlds, climate change is real. Even my amateurish, admittedly clunky analyses makes that glaringly obvious

A warming trend in Boston does not make global climate change "glaringly obvious", and for somebody with an obvious statistical training to say so is even more disappointing.

(Please read my argument carefully: I am not arguing anything at all about the existence of global climate change!)

I was also very surprised that the author didn't mention the urban heat island effect. While some of the temperature increase can be attributed to global warming, some of it might also be showing that Bostan has become more urbanized since 1890.

True. To people living in Boston, that still implies the climate has changed, though. It just means it's a stretch to infer anything about the world from it (not that this would be a good idea even in the absence of the heat island effect.)

That's "local climate change" and he clearly said "global climate change".

It does show a glaring change in Boston's climate. If you read the page carefully, nowhere does the author say anything about global climate.

1) "Speaking of worlds," implies that he's talking about global climate change.

2) "climate change is real" refers to the idea of global climate change, you will be unable to convince me that he's referring to a common belief in "Boston climate change".
