✦ Synopsis

Many general circulation models suggest that current precipitation amounts in polar latitudes will increase under double CO 2 scenarios. Even though temperatures in such high-latitude regions should also increase under a doubling of CO 2 , as long as those temperatures remain below freezing, the increased precipitation should accumulate as snow. A study of both current and double CO 2 temperature and precipitation data for all land areas poleward of 60 latitude using three different general circulation models suggests possible changes in snow accumulation due to increasing CO 2 . Increased snow accumulation will occur in the Antarctic whereas a small decrease in snow depth is to be expected in the Northern Hemisphere. Total snow accumulation for all land areas poleward of latitude 60 is found to increase under a double CO 2 scenario.

## Abstract We used remotely sensed weekly snow water equivalent (SWE) and snow cover extent (SCE) data to investigate streamflow response to seasonal snowcover change over the Yukon watershed. We quantified the seasonal cycles and variations of snowcover (both SWE and SCE) and river streamflow, an
