I read somewhere that the *gulf stream (orig jet stream, thanks!) makes similar latitudes more temperate in Britain/Europe than Canada/America. whether it's attributable to the jet stream or other effects, it seems to be true for many locations. Much of the UK lines up with Hudson bay in Canada, or Scandinavia vs northern Canada/mid Alaska. It's telling that most European colonizers moved south as they crossed the Atlantic.
