ELI5: Why does New England have cold an snowy winters even though they are on the same latitude as southern Europe?
gpt
Latitude is only one part of the formula that determines local climate. One very important factor is the Gulf Stream: a flow of warm water that goes north from Florida before crossing the Atlantic around Newfoundland and then follows the European coastline. The warm water helps make the climate of Europe mild, but because the stream is a ways off from the coastline in northern North America, New England (and more so, the Canadian region of Labrador) are left comparatively cold.

Incidentally, New England also has a rather humid climate, which encourages snowfall when it is cold.
