Slide 18 of 24
Notes:
We looked at 8 scenarios produced by several different general circulation models from climate modeling centers around the world. We averaged the results for the Pacific northwest and compared them with the “control” climate from long runs with fixed CO2, recalibrated to 1990s mean. In the table above I’ve highlighted the average values (red), broken down into the warm half and cool half of the year. The bottom line: warmer and wetter.
- using just June-July-August, most of the models project a decrease in summer precipitation.
- The 2C warming exceeds the 20th century warming (0.8C in the Northwest)
