Should we lay down er sumfin? Putta bag o'er our 'eds?

This is the best summary I could come up with:

Earlier this month, a sudden atmospheric warming event caused the Arctic's polar vortex to reverse its trajectory.

The swirling ring of cold air is now spinning in the wrong direction, which has triggered a record-breaking "ozone spike" and could impact global weather patterns.

The polar vortex circling the Arctic is swirling in the wrong direction after surprise warming in Earth's atmosphere triggered a major reversal event earlier this month.

The current reversal is the second of its kind this year, following a smaller event in January that did cause a brief cold snap in some states, Butler wrote in NOAA's polar vortex blog.

Historical records show that SSW events are more likely to occur during El Niño or La Niña, the two contrasting phases of a natural cycle of planet-wide warming and cooling.

During these phases, global weather systems become more unstable, which sets the stage for more frequent reversal events, Butler wrote in the NOAA blog.
