Glaciers can be caused by global warming this way:
The warming up reduces the temperature difference between
arctic seas and tropic seas. This makes the gulf stream stop moving or
change path.
As a result, the north pole is blocked off the warm waters and starts to
cool down,
creating further tundra and arctic tiles at the north pole.
