How is it that palm trees thrive in the middle of winter at a place farther north than cities that have some of the harshest winters in North America? Sea surface temperatures can tell you something about out how this can happen. In this step, you'll record sea surface temperatures (SST) for Canadian and European cities at similar latitudes.
! Click
the red dot labeled "Canadian Cities" and record average
July SST for Halifax and St. Johns, Canada. Click the
dot labeled "European Cities" to record July data for
Cork, London, and Amsterdam. Click January below the
