The video was created from photographs taken in early November on a nearly full-moon night. The lasers appear curved due to a projection effect.

Updating my Arctic amplification slides... Pick any month and you will see accelerated warming.
So, even if there are linear trends elsewhere, there has to be an acceleration globally, if somewhat more muted compared to the larger changes happening at high latitude. #climate 🧪
