Thanks for your comment. We agree, it would be useful to compare the forecasts for the polar vortex with how they actually performed; we can look into this for the winter recap.

We appreciate your suggestion to include less uncertainty in the discussion and will consider this for future posts. However, it is our view that while to the public eye it might appear that there is peer review consensus on this subject, in reality this is a pretty new area of research, and some of the mechanisms and causality remains untested. Nonetheless we want to acknowledge that these theories are out there and actively being researched.
