Trace of rain fell yesterday at MSP.
4th warmest. Combined land-sea global temperatures in August tied 2005 for the 4th warmest since 1880, according to NOAA NCDC.
All I want for Christmas is some time away from my laptop, quality time disconnected from The Matrix. That, and an emergency generator would be nice.
Yesterday I spoke to utility executives at The Midwest Energy Association, where I talked about weather & climate trends. Extreme weather has triggered a 10-fold increase in electric grid incidents since 1992 across the USA. Keeping the lights on has become even more challenging. Take nothing for granted.
That, and an update on the sun, at the peak of the solar cycle. It's been very quiet as of late, but in any given decade there's a 12 percent risk of an X-class solar flare capable of bringing down parts of the power grid. Have a nice day!
This is my cue to turn to the sports page.
No weather-gotchas lurking out there anytime soon close to home, although a morning thundershower may jolt you from your stupor. Behind this warm front highs top 80F by late afternoon. A September summer serenade. Soak it up because a fresh push of 60s arrive via Canadian Air Mail Friday & Saturday; weekend lows dipping into the 40s.
Fresh air - low humidity - fewer bugs. Now if we can just get a 2-3 day soaking rainstorm to replenish soil moisture we'll be in great shape!

0.1 percent, the probability of such a rainstorm occurring in any given year in Boulder County (“Such values shouldn’t be taken as gospel—there are important caveats, including the hard-to-model behavior of the most extreme events—but they do suggest how truly noteworthy this week’s rains were,” writes Bob Henson, of the National Center for Atmospheric Research)..."

No one has been able to access the town until late Sunday afternoon when crews finalized repairs of the upper portion of the road for emergency traffic only. The town has no infrastructure or running water. Some parts of town amazingly enough have electricity. A dozen or so residents stayed as most of the town was evacuated by helicopters."

What's Causing Global Warming? Look For The Fingerprints. Here's an excerpt of an article at The Guardian: "...What did they find? Certain patterns emerge that are consistent with the "human only" scenario. For instance, the heating of the lower atmosphere and cooling of the upper atmosphere, which satellites clearly see, could only happen if human emissions were the culprit. But the study went further; they actually stacked the deck of cards in favor of nature. They used solar and volcanic variations much larger than those that actually occurred since 1979. The strategy was to see if even a worst case "world without us" could be made to look like the current measurements. But, even that didn't work. The human influence still stood out. Perhaps the best summary is in the abstract of the paper.
"We show that a human-caused latitude/altitude pattern of atmospheric temperature change can be identified with high statistical confidence in satellite data. Results are robust to current uncertainties in models and observations … Our results provide clear evidence for a discernible human influence on the thermal structure of the atmosphere".
