A phenomenon called noctilucent clouds is possibly one more sign that the times they are a changin’. “The clouds are on the move, brightening and creeping out of polar regions, and researchers don’t know why” according to an article I just found on AOL: Mysterious Clouds Creeping Out of the Arctic.

Satellite technology now allows us to view and track these strange clouds that are forming above both poles. We don’t seem to fully understand why the clouds form or what is behind the changes that are being seen, but hopefully new technology will allow us some insight. Some think it might be part of atmospheric changes caused by global warming, but as of now, we just don’t know.

All I know for sure is that they are magnificent to look at. And just a little scary.
