However, the models agree far less about streamflow
patterns during the rest of the year (Figure 3 - 12), with some projecting increases in streamflow in summer and fall, while others project reduced streamflow during these months.
Over the past 60
years, Alaska has warmed more than twice as rapidly as the
rest of the United States, with state - wide average annual air temperature increasing by 3 °F and average winter temperature by 6 °F, with substantial
year - to -
year and regional variability.1 Most
of the warming occurred around 1976
during a shift in a long - lived climate
pattern (the Pacific Decadal Oscillation [PDO]-RRB- from a cooler
pattern to a warmer one.
