We finally have cold weather and snow. That polar vortex is back too. This morning is barely "subzero" (-1F/-18C, windchill -14F/-25C), but it's been a lot colder recently.

I spent this week a little farther north than usual. Where I work (with The Nature Conservancy), they have a conference once every three years that brings together employees from Minnesota, North Dakota, and South Dakota. We met at a location close to all of us, a small resort in Ottertail, Minnesota. Unfortunately, the weather there reached a low of -13F/-25C (windchill -30F/-34C), so I never went outside during the event. The weather didn't cooperate, so they cancelled the sleigh ride, cross-country skiing, ice fishing, and even the evening campfire.

The experience was good, though. I have a much better sense of what my coworkers are doing. I learned some cool stuff too. The state of Minnesota makes available some great datasets from LiDAR surveys. They are very detailed, and they can detect both tree canopy and ground level. I also learned that North America's grasslands are useful as carbon sinks, storing several tons per acre under the roots of those grasses. Unfortunately, we're losing grasslands at a faster pace than the world is losing rainforest. Meanwhile, I gave a presentation with my tech support coworker on what to do when your email inbox reaches its quota. It's not a particularly exciting topic, but people seemed to take away tidbits that they thought were useful to their own work life.

drive in snowWe heard the bad weather forecasts, so organizers sent the South Dakota people home early to escape the expected bad driving conditions. The next morning, however, it seemed that South Dakota escaped the snowfall while the rest of us were just beginning to receive it. Instead of a final buffet lunch, we got boxed sandwiches so we could get in our carpools and head home immediately. No luck, though, because the weather system was already covering our route. It took much longer than usual to get back.

I took this photo while we were traveling slowly along the interstate highway back to Minneapolis. We saw several accidents and near-accidents, but I was delivered by my carpool safely back home.

We're forecast for above-freezing days soon, so we'll get more thawing in January.  Winters here are getting easier each year.  Normally, we'd have an arctic landscape outside, with boring snow cover from first snowfall (November or December) until thaw (around April).  Now, though, it seems that we will have "punctuated" winters where the snow actually melts between downpours.

Climate change is interesting, at least.
