Holocene, thereby placing the magnitude and rate of change in recent years within a longer perspective. This need is especially true in the High Arctic, where global circulation models (GCMs) predict an amplified response to greenhouse gas-induced warming (Zwiers, 2002), yet few long-term high-resolution climate data sets exist. In the Arctic

effects of end-of-the-century projected Antarctic sea ice loss extend much further than the tropics, and are able to produce considerable impacts on Arctic climate. Specifically, our model indicates that the Arctic surface will warm by 1 C and Arctic sea ice extent will decline by 0.5 × 106 km2 in response to future Antarctic sea ice loss.

Arctic climate change: observed and modelled temperature and

Changes apparent in the arctic climate system in recent years require evaluation in a century-scale perspective in order to assess the Arctic s response to increasing anthropogenic greenhouse-gas forcing. Here, a new set of century-and multidecadal-scale observational data of surface air temperature (SAT) and sea ice is used in combination with

A Paleoclimatic Perspective on Abrupt Climate System Change

1)Abrupt change is not exceptional, but rather is a normal way in which the climate system responds to changes in forcing. 2) Regional forcing can trigger widespread changes (global and far-field remote). 3) Abrupt climate change occurs naturally in aspects of climate that are highly relevant to society (e.g., droughts,

Antarctic Climate Change and the Environment

We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have

direct effects of climate change is, of course, an increase in ambient temperature in the Arctic. This warming, in particular, has reduced the amount or extent of sea ice, which is very important for protecting coastal villages from erosion.
