jQuery1368780234047="58">Glaciers distinct from the Greenland and Antarctic Ice
Sheets are losing large amounts of water to the world’s oceans. However,
estimates of their contribution to sea level rise disagree. We provide a
consensus estimate by standardizing existing, and creating new, mass-budget
estimates from satellite gravimetry and altimetry and from local glaciological
records. In many regions, local measurements are more negative than
satellite-based estimates. All regions lost mass during 2003–2009, with the
largest losses from Arctic Canada, Alaska, coastal Greenland, <U>the southern
Andes</U>, and high-mountain Asia, but there was little loss from glaciers in
<U>Antarctica</U>. Over this period, the global mass budget was –259 ± 28
gigatons per year, equivalent to the combined loss from both ice sheets and
accounting for 29 ± 13% of the observed sea level rise. </P>

<P id=p-2>Glaciologists trekking onto remote, inhospitable streams of flowing
ice have brought back some especially bad news. But then 21st century monitoring
from space began to show a much smaller role for glacial ice loss in sea-level
rise. Which to believe? A new study brings together both boots-on-the-ice and
high-tech glaciologists, saying that although the field measurements were
painting an accurate picture of the few glaciers being monitored, they were not
representative of the world's glaciers. <A
href="http://www.sciencemag.org/content/340/6134/852.abstract">All 19
glacierized regions of the world are losing ice</A>, the study finds, but the
iconic glaciers long-studied by field glaciologists are disappearing faster than
most. Still, the world's glaciers are losing ice just as fast as the great ice
sheets. </P></DIV><SPAN
