Snow Cover

Note: Global warming is increasing the moisture content of the atmosphere due to warmer oceans. This could manifest as an increase in snow extent. The warmer atmospheric temperatures altering season lengths should melt the snow faster in the spring. The data does indicate this to be true. We will add to this section if direct attribution studies are conducted.
