What's your winter favorite - ice or snow?

Sailing on top of the world – Part 2
In the last column, I wrote about the physical changes occurring in and around the Arctic Ocean. Those changes are occurring due to climate change. Shipping lanes are being used for commerce,...
Sailing on top of the world

Morgan Spurlock, a documentary filmmaker, went on a 30-day McDonald’s fast-food diet and he ended up with health problems. He documented his feast in his film “Super-Size Me.” When we satisfy ou...
El Niño and the ENSO
In past columns I’ve talked about the El Niño Southern Oscillation (ENSO), or as some call it, the Southern Oscillation. Let me briefly review what this thing does. There are two ocean temperature...
Shimmering clouds and good wine

And the snow fell, a little
Early November teased us a little bit with measurable snowfall that apparently has stalled. Not to worry, ski fans and snow junkies, it will snow again. I spent some time looking at what winter may...
Do we really know our air quality?
Air quality alerts are common in many regions of the world. The United States experiences air quality alerts regularly too. The causes are wide ranging and many are seasonal in nature. Of concern in...
What will winter bring?
I’ve licked my finger, held it up to the air; now I can tell you what winter will bring. If only it were that simple! So, let me share what is being stated by our federal agencies that work in the arena of weather prediction. First, let’s take a...
