The April issue of Weather has a review of a book about the
Tambora
eruption. In the review, it says that the "eruption was bigger
by at
least one order of magnitude than any before it." Should he
have
added something on the lines of "except for the mystery
eruption that
occurred only seven years earlier which may have been as big
and had a
greater effect on the climate"?

And the Toba eruption several tens of thousands of years ago?
