Here in Fairbanks, we have been experiencing a remarkably cool and snowy spring. We had a significant snowfall during the PolarTREC orientation in late March, and then we had another snowstorm several weeks later, in April. I classify a "significant snowfall" as one that requires me to get out my snow blower. This past weekend was bright and sunny, with the temperatures (finally?) reaching up above freezing. Although winter's snow accumulation has started to melt, I am reminded of the difference between "weather" and "climate."
Fairbanks is experiencing an extended snow season this year. The local weather has been cooler and snowier than average.
Weather vs. Climate
Although Fairbanks has been experiencing below-average temperatures with additional snow in March and April this year, this is just a local weather pattern. When we speak of climate and climate change, we are referring to overall trends in the global climate. This involves much larger regions being affected by the climate conditions over much longer time periods. It is good to keep this difference in mind as we complain about or rejoice in whatever local weather event is happening. At least my dog enjoys the still-deep snow!

The Lighter Side…
Still, in regards to our local weather being rather cold and snowy this spring, I have to laugh when I see the bumper sticker proclaiming: "Alaskans for Global Warming!"
