Monthly carbon dioxide concentration since 1958 from the NOAA Mauna Loa Observatory, Hawai'i. Last month's average concentration of 426 parts per million is 36 percent higher than in November 1958. The 10-year forecast is based on nothing but the recent trajectory of CO₂ concentrations. #Climate

Prior to today, the greatest hourly precip value at PAFA since 1950 with a temp of -9F or colder was 0.04". That has been exceeded 5 times today. So while it is never too cold to snow, this is an exceptional "cold snow" event.
