After a warm dry summer this is a good time to take a look at the global warming scorecard for our region. Using Olympia Airport as perhaps our best measure of temperature in the Puget Sound region, we find the following:
50.68 F — Mean temperature 1990 – 1994
50.76 F — Mean temperature Sept 2016 – Aug 2017
We see over the past 25 years the temperature rise in our region has been about +0.08 deg F. The forecast by the U of WA Climate Impacts Group (CIG) in the 1990s was for a temperature rise of +3.1 F by the 2020s. With only 3% of the anticipated warming in hand so far, and with only two years remaining until the start of the 2020s, the climate has a lot of catching up to do. Either that or the Climate Impacts Group forecast will end up being considerably too warm.
Winter has arrived in Oregon! This morning has seen sub-zero temperature readings in eastern Oregon.
