Abstract

"Norway and New Zealand both experienced recent glacial advances, commencing
in the early 1980s and ceasing around 2000, which were more extensive than
any other since the end of the Little Ice Age. Common to both countries, the
positive glacier balances are associated with an increase in the strength of
westerly atmospheric circulation which brought increased precipitation. In
Norway, the changes are also associated with lower ablation season
temperatures. In New Zealand, where the positive balances were distributed
uniformly throughout the Southern Alps, the period of increased mass balance
was coincident with a change in the Interdecadal Pacific Oscillation and an
associated increase in El Niño/Southern Oscillation events. In Norway, the
positive balances occurred across a strong west-east gradient with no
balance increases to the continental glaciers of Scandinavia. The Norwegian
advances are linked to strongly positive North Atlantic Oscillation events
which caused an overall increase of precipitation in the winter accumulation
season and a general shift of maximum precipitation from autumn towards
winter. These cases both show the influence of atmospheric circulation on
maritime glaciers."

KlimaNotizen will dazu beitragen, dass die öffentlichen Diskussionen zur allgemeinen Klimaentwicklung ausgewogener werden.
Daher stehen hier vor allem Informationen, die in der öffentlichen Wahrnehmung zu kurz zu kommen scheinen.
Und daher ist KlimaNotizen selbst auch nicht ausgewogen.
Wer sich ein möglichst objektives Bild über Erkenntnisse und Meinungen verschaffen möchte, sollte selbst alle Informationen zur Kenntnis nehmen.
