Considering a 4 degree rise in temperature within 30 to 60years how high of a latitude would you need to be to farm relatively successfully?

This is something that's actually starting to happen - for instance, in the San Francisco Bay Area, there are a hell of a lot of wineries thanks to a historically Mediterranean climate that favored growing grapes.

However, lately a lot of these wineries/grape farms have been popping up in central Oregon, since now it isn't snowing all that much there anymore.

Now for some /r/theydidthemath bullshittery-

The Earth has warmed about 1.25C so far, and the difference between Napa, CA and Eugene, OR is about 6 degrees.

So that's about 4.8 degrees north for every 1C of warming (ignoring topography/geography, elevation, actual weather patterns, and pretty much everything else lol).

At +4C, that allows an additional ~+19 degrees latitude for growing the same crop.

So I'd say that +4C temp rise could result in wineries popping up in Seattle, WA and Vancouver, BC.

Again, completely ignoring pretty much all of reality.
