What Will UnWinter Be Like?

Cold night temperatures with no snow create a dilemma for the crew at Rancho San Rafael Park in Reno, how to water the grass without risking the sprinkler system?

Cold night temperatures with no snow create a dilemma for the crew at Rancho San Rafael Park in Reno. How to water the grass without risking the sprinkler system at night?

282°  We still have Winter in Reno. It’s strange, but it’s still cold at night and in the mornings. The below freezing temperatures have allowed frost to form on the ground, which makes the grass damp in the mornings.

That may change in the next decade or so. NASA has tracked our global average temperatures since the 1950’s and the data shows a consistent trend of global warming. Every fact indicates that the trend of the last 60 years will continue and possibly accelerate. That may result in Winter becoming UnWinter.

Like ice melting ice in a beer cooler we still have blasts of cold air coming down from the Arctic via the Polar Jet Stream. That river of air is being reinforced by water vapor from the melting permanent ice rushing to meet warm air coming up from the equator. Once the ice melts, the Polar Jet will no longer have the engine that drives it South.

No Polar Jet Stream, no cold air. No cold air, no Winter. UnWinter. Short days, long nights, cool temperatures but no frost and no snow. It’s hard to fathom the issues that will come with UnWinter, but they will likely be unpleasant and expensive.
