Now draw a picture of the
globe and show on it what you call «
average temperatures» for whatever zones you choose to draw on it; then show recent variations from those «
averages» — the variations from the longterm
average in a higher latitude zone don't mean as much, because we're comparing today's measurement to
averages based on fewer numbers, collected
over fewer years in fewer places, when looking at variation near the Poles.
