Arctic Litter - NOT amateur radio
At my U3AC course yesterday at the Scott Polar Research Institute in Cambridge we were told an amazing fact. Litter in the Arctic Ocean has increased 20-fold in the last 10 years.

Cold Arctic
See http://www.spaceweather.com/ .
The Space Weather website has some great images of stratospheric polar clouds saying the Arctic Circle is getting very cold.
Mesospheric clouds (higher than the stratosphere) are often associated with 6m DX from Europe to Japan. I don't know if such propagation is possible at this time of year. These openings are usually in late June, I think.
I don't know if stratospheric clouds reflect radio waves as do mesospheric clouds.
See https://www.nasa.gov/mission_pages/sunearth/science/atmosphere-layers2.html for details of atmospheric layers.
