The days are getting noticeably shorter as we approach the Winter Solstice on December 21. It's been cold this week even though we've had bright sunny days. The morning sun shines on the frosty grass as we start our day at the Middle School. The frost soon disappears, but the chill remains throughout the afternoon. How can it be stay so cold despite the bright sun? Why does the winter sun provide so little heat?
