|a The glaciers of Alaska and northwestern
Canada have long been considered
important contributors to global
sea level, but their remoteness has complicated
efforts to quantify how their mass is
changing. Nearly 30 years ago, the first
regional assessment—based on data from
only three glaciers and a largely intuitive
regional extrapolation scheme—suggested
that Alaska’s glaciers accounted for more
than one-third of the total sea-level contribution
from glaciers and ice caps (excluding
ice sheets) ( 1). Recently, global maps of
water-mass variations, developed using satellite
measurements of Earth’s gravitational
fi eld (gravimetry), confi rm with remarkable
clarity the large role Alaska glaciers play in
the global sea-level budget (see the fi gure).
Far from solving the puzzle, however, these
and other new observation technologies are
revealing unexpected complexities in the
magnitude and rate at which Alaska glaciers
respond to climate. |
